A little over two years ago, a tiny piece of code was introduced to the internet that contained a bug. This bug was known as Heartbleed, and in the two years it has taken for the world to recognize its existence, it has caused quite a few headaches. In addition to allowing cybercriminals to steal passwords and usernames from Yahoo, it has also allowed people to steal from online bank accounts, infiltrate governments institutions (such as Revenue Canada), and generally undermine confidence in the internet.
What’s more, in an age of cyberwarfare and domestic surveillance, its appearance would give conspiracy theorists a field day. And since it was first disclosed a month to the day ago, some rather interesting theories as to how the NSA and China have been exploiting this to spy on people have surfaced. But more on that later. First off, some explanation as to what Heartbleed is, where it came from, and how people can protect themselves from it, seems in order.
First off, Heartbleed is not a virus or a type of malware in the traditional sense, though it can be exploited by malware and cybercriminals to achieve similar results. Basically, it is a security bug or programming error in popular versions of OpenSSL, a software code that encrypts and protects the privacy of your password, banking information and any other sensitive data you provide in the course of checking your email or doing a little online banking.
Though it was only made public a month ago, the origins of the bug go back just over two years – to New Year’s Eve 2011, to be exact. It was at this time that Stephen Henson, one of the collaborators on the OpenSSL Project, received the code from Robin Seggelmann – a respected academic who’s an expert in internet protocols. Henson reviewed the code – an update for the OpenSSL internet security protocol — and by the time he and his colleagues were ringing in the New Year, he had added it to a software repository used by sites across the web.
What’s interesting about the bug, which is named for the “heartbeat” part of the code that it affects, is that it is not a virus or piece of malware in the traditional sense. What it does is allow people the ability to read the memory of systems that are protected by the bug-affected code, which accounts for two-thirds of the internet. That way, cybercriminals can get the keys they need to decode and read the encrypted data they want.
The bug was independently discovered recently by Codenomicon – a Finnish web security firm – and Google Security researcher Neel Mehta. Since information about its discovery was disclosed on April 7th, 2014, The official name for the vulnerability is CVE-2014-0160.it is estimated that some 17 percent (around half a million) of the Internet’s secure web servers that were certified by trusted authorities have been made vulnerable.
Several institutions have also come forward in that time to declare that they were subject to attack. For instance, The Canada Revenue Agency that they were accessed through the exploit of the bug during a 6-hour period on April 8th and reported the theft of Social Insurance Numbers belonging to 900 taxpayers. When the attack was discovered, the agency shut down its web site and extended the taxpayer filing deadline from April 30 to May 5.
The agency also said it would provide anyone affected with credit protection services at no cost, and it appears that the guilty parties were apprehended. This was announced on April 16, when the RCMP claimed that they had charged an engineering student in relation to the theft with “unauthorized use of a computer” and “mischief in relation to data”. In another incident, the UK parenting site Mumsnet had several user accounts hijacked, and its CEO was impersonated.
Another consequence of the bug is the impetus it has given to conspiracy theorists who believe it may be part of a government-sanctioned ploy. Given recent revelations about the NSA’s extensive efforts to eavesdrop on internet activity and engage in cyberwarfare, this is hardly a surprise. Nor would it be the first time, as anyone who recalls the case made for the NIST SP800-90 Dual Ec Prng program – a pseudorandom number generator is used extensively in cryptography – acting as a “backdoor” for the NSA to exploit.
In that, and this latest bout of speculation, it is believed that the vulnerability in the encryption itself may have been intentionally created to allow spy agencies to steal the private keys that vulnerable web sites use to encrypt your traffic to them. And cracking SSL to decrypt internet traffic has long been on the NSA’s wish list. Last September, the Guardian reported that the NSA and Britain’s GCHQ had “successfully cracked” much of the online encryption we rely on to secure email and other sensitive transactions and data.
According to documents the paper obtained from Snowden, GCHQ had specifically been working to develop ways into the encrypted traffic of Google, Yahoo, Facebook, and Hotmail to decrypt traffic in near-real time; and in 2010, there was documentation that suggested that they might have succeeded. Although this was two years before the Heartbleed vulnerability existed, it does serve to highlight the agency’s efforts to get at encrypted traffic.
For some time now, security experts have speculated about whether the NSA cracked SSL communications; and if so, how the agency might have accomplished the feat. But now, the existence of Heartbleed raises the possibility that in some cases, the NSA might not have needed to crack SSL at all. Instead, it’s possible the agency simply used the vulnerability to obtain the private keys of web-based companies to decrypt their traffic.
Though security vulnerabilities come and go, this one is deemed catastrophic because it’s at the core of SSL, the encryption protocol trusted by so many to protect their data. And beyond abuse by government sources, the bug is also worrisome because it could possibly be used by hackers to steal usernames and passwords for sensitive services like banking, ecommerce, and email. In short, it empowers individual troublemakers everywhere by ensuring that the locks on our information can be exploited by anyone who knows how to do it.
Matt Blaze, a cryptographer and computer security professor at the University of Pennsylvania, claims that “It really is the worst and most widespread vulnerability in SSL that has come out.” The Electronic Frontier Foundation, Ars Technica, and Bruce Schneier all deemed the Heartbleed bug “catastrophic”, and Forbes cybersecurity columnist Joseph Steinberg event went as far as to say that:
Some might argue that [Heartbleed] is the worst vulnerability found (at least in terms of its potential impact) since commercial traffic began to flow on the Internet.
Regardless, Heartbleed does point to a much larger problem with the design of the internet. Some of its most important pieces are controlled by just a handful of people, many of whom aren’t paid well — or aren’t paid at all. In short, Heartbleed has shown that more oversight is needed to protect the internet’s underlying infrastructure. And the sad truth is that open source software — which underpins vast swathes of the net — has a serious sustainability problem.
Another problem is money, in that important projects just aren’t getting enough of it. Whereas well-known projects such as Linux, Mozilla, and the Apache web server enjoy hundreds of millions of dollars in annual funding, projects like the OpenSSL Software Foundation – which are forced to raise money for the project’s software development – have never raised more than $1 million in a year. To top it all off, there are issues when it comes to the open source ecosystem itself.
Typically, projects start when developers need to fix a particular problem; and when they open source their solution, it’s instantly available to everyone. If the problem they address is common, the software can become wildly popular overnight. As a result, some projects never get the full attention from developers they deserve. Steve Marquess, one of the OpenSSL foundation’s partners, believes that part of the problem is that whereas people can see and touch their web browsers and Linux, they are out of touch with the cryptographic library.
In the end, the only real solutions is in informing the public. Since internet security affects us all, and the processes by which we secure our information is entrusted to too few hands, then the immediate solution is to widen the scope of inquiry and involvement. It also wouldn’t hurt to commit additional resources to the process of monitoring and securing the web, thereby ensuring that spy agencies and private individuals are not exercising too much or control over it, or able to do clandestine things with it.
In the meantime, the researchers from Codenomicon have set up a website with more detailed information. Click here to access it and see what you can do to protect yourself.
And we’re back with more of the 2014 Williams’ Family Eurotrip. Today’s subject: the three days and two nights we spent in the historic town of Bayeux in the Normandy region. The highlights while staying there involved learning of my grandmother’s cousin, Wilmot Pettit, touring the historic city, visiting several World War II cemeteries, seeing the Bayeux Tapestry, and visiting the D-Day landing sites of Gold and Juno Beach. And of course, our accommodations were once again kick-ass!
Tuesday, April 15h – Thursday, April 17th – Bayeux: Tuesday morning began as all our mornings did, with breakfast in the hotel followed by us packing up the car and hitting the road for the day! Our next destination was the Normandy town of Bayeux, which is located just 7 km (4.3 miles) from the coast and sits on River Aure. In addition to being very scenic and well-situated for our purposes, Bayeux also had two things going for it in terms of its history. One, it was the first town liberated by the Allies during the Battle of Normandy. And two, it is the home of the Bayeux Tapestry, an historic artifact that is listed as a “Memory of the World” by UNESCO.
But before we could arrive there, there was the matter of retracing some family history. Prior to leaving, my folks had been informed by my grandmother that one her cousins – who lived next door to her growing up in Bramford, Ontario – had been shot down in Normandy and was buried there. After some quick research, they had a name and some clue as to his whereabouts. Wilmot Pettit, who enlisted with the Royal Canadian Air Force in 1940 and was shipped to Britain.
Four years later, he was promoted to the rank of Squadron Leader and participated in the greatest undertaking in history – Operation Overlord, the invasion of Normandy. As part of the Eastern Task Force, his air unit was responsible for escorting members of the British 6th Airborne to their landing sights south of Sword Beach to the north-east of Caen. This consisted of his Shorts Stirling Mk IV bomber towing a glider packed with British Airborne troops to their destination. Unfortunately, his plane was shot down by German anti-aircraft artillery, and went down near the town of Grangues.
Armed with that knowledge, as well as what could be gleamed from the town’s website, we programmed the town of Grangues into Betty (our semi-affectionate name for the GPS), we set off for the Normandy countryside. Eventually, we found the hamlet, which consisted of a church and a school located a little farther on, which just happened to have the mayor’s office attached. This we entered, hoping they might have some information on this event that took place outside of his town some 70 years ago.
The Church at Grangues
To our surprise, the Mayor had more than a little; in fact, he had volumes! In addition to his office containing a case filled with the remains of a glider, pictures of some of those who survived, and a painting of the Stirling flying above the trees with its wings on fire, he had pictures, documents, and pointed us in all the right directions. He even escorted us to the field where Wilmott’s plane, in addition to several other gliders, crashed – which was at one time the estate known as the Chateau Grangues.
It was a wonderful opportunity for my mother and I to practice our French, and the Mayor extremely helpful and patient with us. We quickly learned that Wilmot’s plane was one of several Allied craft that went down in the region. According to the 591 Antrim Parachute Squadron‘s ongoing inquiry into the matter, Two Stirlings and four Horsa Gliders have been shot down by German anti-aircraft guns, and landed in the fields outside of this small village.
My folks and I listening to the Mayor (far right)
When Wilmot’s plane went down, he and most of the airborne troops died in the crash. The handful that survived were taken prisoner by the German 711 Division that were occupying the region. Several of these men were later shot, in what the German soldiers claimed was “an attempted breakout” (though this has never been confirmed). To the mayor’s knowledge, Wilmot and all the others who perished on that “day of days” were interred in the Commonwealth Cemetery at the nearby town of Ranville.
He also said he had some photos which he would send us home with, but he never was able to find them. He did however promise to mail them as they turned up. We thanked him for his immense help and did a little searching of the fields, hoping to find some remains that we ourselves could take home and show to my grandmother. It was quite an exciting thing, finding a personal connection to the war and being able to walk on the very land where it happened.
The commemorative plaque outside of the Grangues church
Unfortunately, the crash site consisted of grown-over fields and a lot that had been set aside from construction, and all we could find after a few hours of looking was a rusted piece of metal that we took for an old bullet fragment. Still, we felt our mission was a grand success, thanks in no small part to the lovely people of Grangues and their infinitely helpful mayor. We also were sure to visit the commemorative plague that sat outside the church, which had the names of all those who perished in the crash and at the hands of the German soldiers, along with the French and British flags flanking it.
I should also note that the church had a lovely spring out in front of it. Water poured down a stone chute from the hill’s underground aquifer and entered into a basin with a statue of the Virgin Mary over top of it. People came from all around while we were there to fill up their jugs and take it home. And this was in spite of the fact that the water basin had a warning sign that said that the town was not responsible for any illness incurred from drinking it. Ah, legalities!
Wilmot Pettit’s headstone, Ranville War Cemetery
And then, it was off to Ranville, which proved to a small town – though compared to Grangues, it was a minor megapolis. Once there, we grabbed some lunch from a local bakery, which consisted of water and/or Orangina and some sticks of bread with cheese and ham baked in. We downed these at the local park, and entered the Ranville War Cemetery, and found Wilmot Petitt’s grave (pictured above). As it states on his stone, he was awarded the Order of the British Empire and the Distinguished Flying Cross for his actions.
We placed a Canadian flag pin on his headstone and my mother planted a copy of his story that we printed off next to it. We also planted a Canadian quarter in the soil, and my father sprinkled some dirt from Bramford he had been keeping in a small bottle. He then filled said same bottle with some dirt from next the cemetery, with the intention of bringing it back to BC and showing to my grandma. After that, we went around to pay our respects to other Canadians who had died on D-Day and during the Battle of Normandy.

Then it was into Bayeux, where we found our way to the Lion D’Or (Golden Lion) where we would be spending the next few nights. After finding our room, my folks and wife wanted to go for a walk and visit the local Cathedral. Unfortunately for me, I was far too tired and feeling the effects of a long day out in the sun to join them. So I napped and showered while they explored the cobblestone streets and saw the magnificent Cathedral. Luckily, my wife took plenty of snapshots and told me about their time.
As they inspected these piece of Norman-Romanesque architecture – which is the seat of the Bishop of Bayeux and the original home of the Bayeux Tapesty (more on that later) – the organ music came on. This cathedral has two, incidentally, one which is huge and the other which is massive! As they learned, it was practice time for the organ player, and they were playing everything from hymns to the theme from the Phantom of the Opera.
The Bayeux Cathedral crypt
Then they visited the station’s of the Cross chapels – the Cathedral has one for every station – took some pictures of the beautiful stained glass windows, and then visited the crypt. Down there, frescoes, columns and some trace light coming in from the windows are the only company to those who have been entombed over the years. My wife also claimed that the place could admittedly use some conservation work, but heritage conservation is her field, so this is generally her opinion!
We then met up for dinner at a place near the hotel – La Maison de Terroir (House of the Land) – where we delicious eats that were washed down with a few glasses of Affligem Blonde (the local beer of choice). We then retired to our room for some restful sleep and got up the next day to do the next leg of our tour of World War II sites. Up next was Juno Beach, the Normandy beach where the Canadian forces made their amphibious landing on D-Day.
Juno Beach Centre
It was at this point that we were doing things that I was responsible for researching. World War I had been my father’s project, as he was more than familiar with all the cemeteries, sites and battles that had taken place in the Ypres Salient. But D-Day and the Battle of Normandy were my baby, so allow me to share with all the information I dug up in preparation for this part of our trip. So as always, here is some background. Don’t worry, it’s short this time!
On June 6th, 1944, the Allies unleashed the greatest invasion in history. After several years of chipping away at Nazi Germany’s war machine with successful campaigns in North Africa, Sicily, Italy, and in the Atlantic, it was decided that the time for a “Second Front” in Western Europe had finally come. In the east, the Russians had been steadily dealing defeat after defeat against the Germans forces for two years, beginning with Moscow in 41′, Stalingrad in 42′, and then Kursk in 43′. With a full-scale invasion that would at long last liberate France, Hitler’s ultimate defeat would become an inevitability.
Having learned the lessons of Dieppe, the Allies understood the importance of both naval and air support. Because of this, the landing on the Normandy coast would be preceded by a massive bombing campaign by the US, British and Canadian air forces. All along the coast and interior, German fortifications, supply depots, supply lines, and even towns were bombed heavily. The US and British navies also positioned themselves off the coast and began bombarding the beaches a few hours in advance of the landings.
While this was taking place, members of the American 101st and 82nd Airborne Divisions would be landing in the Western Sector of Normandy near the towns of St-Mère-Église and Carenten. In the Eastern Sector, the British 6th Airborne dropped in near Ranville and Bénouville using gliders. Landing behind enemy lines, their mission was to secure causeway exits to ensure that the Allied landings would be able to reach inland without opposition, as well as to destroy inland batteries and securing and destroying bridges to prevent a German counter-attack.
As part of these preparations, the Allies also conducted a massive campaign of deception leading up to the invasion of Normandy. Having learned of the value of secrecy and surprise, they had been circulating false information for months that claimed they were preparing for an invasion of the Pas de Calais in July. The Normandy landings, according to the false information that was being fed to the Germans, was merely a diversion to force the occupiers to pull forces away from this region.
In addition to false radio broadcasts and reports fed to German double-agents, a fictitious First U.S. Army Group was created, supposedly located in Kent and Sussex under the command of Lieutenant General George S. Patton. Using dummy tanks, trucks, and landing craft that were positioned near the coast, the illusion was very much believable, and Hitler became convinced that the Normandy landings genuinely were a feint to lure German forces away from the real invasion.
But in reality, the Allied assault on the five beaches of Normandy – Omaha and Utah in the American sector; Gold, Juno and Sword in the British sector. And at Juno, the 3rd Canadian Infantry Division and the 2nd Canadian Armored Brigade was responsible for clearing the beachhead. As part of the British 2nd Army’s assault on Gold, Juno and Sword in the Eastern Sector, they were tasked with entering the beach at Courseulles-sur-Mer, Bernières, Saint-Aubin, and reaching inland as far as the town of Caen.
To make all this information more personal and relevant, my father recommended I research a soldier (one who was possibly related to our family) and find out what role they played. After doing some preliminary digging, I learned that two Williams’, both of whom were interred at the Commonwealth Cemetery at Beny-sur-Mer. Since my father had already researched Fred Williams of Cornwall, Ontario (whom we may very well be related to), I chose William Gordon Williams of Moose Jaw, Saskatchewan.
As a sergeant with the 1st Battalion, Royal Regina Rifles (7th Regiment), in the 3rd Canadian Infantry Division, he landed at Nan Green sector of Juno Beach, just outside of Courseulles-sur-Mer. The assault began at 0630 hours (that’s 6:30 am in civilian speak); and during the first hour, Canadian forces sustained 50% casualties (similar to what occurred at Omaha Beach). Sergeant William G. Williams was one of the fallen, along with 358 other young men. Despite these losses, the Canadians managed to outperform their peers when taking their objectives.
By 1120 hours, the 3rd Division had cleared the beach and entered the town, seizing the bridge over the river Seulles. By 1415 hours, the entire beach was secured and the division moved inland, and were the first forces to secure their objectives. However, they were unable to reach Caen due to the fact that the British at Gold and Sword were unable to link up with them, and due to increased resistance from the 12th SS Panzer Division, a fanatical unit with the Hitlerjugen (“Hitler Youth”). Other objectives, such as the town of Bayeux, also remained in German hands for the time being.
However, over the course of the next week, the Canadians reached farther inland than anyone else, and secured the towns of Autrie and Carpiquet west of Caen. They also managed to hold their ground against the fanatical 12th SS, who lost a third of their armor against the entrenched Canucks. It was also during this time (July 7th) that the SS executed 20 Canadian POWS at the Ardennes Abbey, located northwest of Caen. Lieutenant Fred Williams was one such person. When the Canadians liberated the Abbey on the following day, they found the bodies of their comrades.
Thenceforth, the Canadian forces operated under the “No quarter asked, none given” rule, which in practice amounted to shooting all SS soldiers on sight. For the remainder of June, all operations were aimed at capturing and holding the high ground southwest of Caen and waiting for reinforcements and the 1st and 30th British Corps to arrive north of Caen and south of Bayeux. By July, efforts to secure Caen and its strategic bridges over the Orne River would be altered. Whereas the D-Day plan called it for it be seized in the same day by direct assault, future attempts would involve outflanking it. More on that later…
Juno Beach Centre, front entrance
Anyhoo, we arrived at Juno Beach at the edge of Courseulles-sur-Mer and proceeded to the Juno Beach Centre that sits at the edge of the beach. Inside, we saw an impressive range of displays that spoke of Canada’s involvement in the Second World War, culminating in a video that addressed the Juno Beach landing, the Battle of Normandy, and the importance of remembering their sacrifice. We then popped outside, and walked the beach, taking some pictures and grabbing some more keepsakes.
Naturally, there weren’t pieces of shrapnel or bullet casings lying around, as the tides cleared those away a long time ago. However, we did manage to pick up some scallop shells and a few interesting-looking stones. We also visited the observation bunker that still overlooks the beach, one of several preserved fortifications that is tight by any definition of the word. Farther down, we spotted another that is slowly sinking into the beach, since these heavy concrete structures are just sitting on sand.
Entering the observation bunker
And then, since it was midday, it was time for lunch, which consisted of burgers, hotdogs or sandwiches (and fries) from a vendor down on the boardwalk. Then it was back into the car, as we had to visit the Beny-sur-Mer War Cemetery, where both William G. Williams and Fred Williams are interred, along with 2047 other members of the 3rd Canadian Infantry Division and airmen who perished in the Battle of Normandy. In addition to these two headstones, we also visited the graves of the other soldiers who died at Beny-Sur-Mer, as well as some that shared my mother and wife’s (well close enough) last name – Wilson and Jack.
After all that, evening consisted of eating at La Maison de Terroir again, followed by an evening walk by my wife and I. While were out, we did a little shopping, and chose to buy a bottle of Calvados. For those unfamiliar, this is a special form of apple brandy named after the region of Lower Normandy where it originated. This was something that was recommended to us by a friend, and my father had said he wanted to try it. We also picked up a bottle of Bayeux Cider, another local specialty, and head back to the hotel.
Beny-sur-Mer War Cemetery
Another sound sleep, and Thursday was upon us! As our last day in town, we hoped to cover all the remaining items on our list. This included visiting Arromanches, the town that overlooks Gold Beach and where the Allies constructed the massive artificial harbor that ensured they were able to get supplies to their forces during the Battle of Normandy. We also hoped to see the Bayeux Tapestry (well some of us anyway), and visit the Bayeux War Cemetery – the largest World War II Commonwealth cemetery in France.
First up, it was the Bayeux Tapestry, which was housed in a museum not far from our hotel. Having seen it already, and feeling unimpressed with it, my father decided to revisit the Cathedral and meet up with us later. And so, after breakfast, we walked on over to the museum to get a look at this UNESCO piece of world heritage. Inside, we were given audio devices that told the story of the Tapestry and explained what each section of it meant.
The gate of the Bayeux Tapestry musuem
I have to admit, this portion of the museum was not as fun as I would have thought. The Tapestry is long and quite interesting, but listening to a half-hour audio description and moving along slowly in line with dozens of other people is not such a great way to see it. Luckily, the museum has multiple floors and plenty of exhibits that help put the lengthy historical account into context. There is also the new theater they added that shows a short film that illustrates it quite well.
To break it down, the Tapestry tells the story of William the Conqueror, the King of Normandy who conquered England in 1066 CE. As part of a war of a succession, the story begins with Edward the Confessor sending William’s rival (Harold) to Normandy to name him Edward’s successor. However, while en route, Harold accidentally detours to a neighboring realm where he is taken hostage by Guy, the Count of Ponthieu. After William pays the ransom for Harold, William invites him on a campaign to conquer Brittany.
A section showing the Battle of Hastings
Successful in their campaign, William knights Harold and makes him swear on the Bible and a holy relic to swear his allegiance to William as his future king. Harold accepts, though he is humiliated to do so, and is given leave to return to England to let Edward know that he has accepted. However, Edward dies shortly thereafter and Harold proclaims himself King of England. This coincides with the arrival of Halet’s Comet, which is seen as a bad omen.
News of the coronation reaches William, and he declares war and orders a full mobilization of his troops and ships. They sail to England to meet Harold in battle, but Harold must first do battle in the north. This is known as the Battle of Stamford Bridge, where Harold and his army of Saxons prevail against an invading force of Vikings. His army then rides south to meet William at Hastings. And after a pitched battle, Harold is killed and his army routed. William is proclaimed king in 1066.
The Bayeux War Cemetery, with the Memorial in the distance
Of particular interest to us was the end of the film where it says that in the Bayeux War Cemetery, a sort of riposte is made to the Bayeux Tapestry. At this Commonwealth Cemetery – which honors British and other soldiers who fell during the Normandy campaign – there is a memorial that states in Latin “We, once conquered by William, have now set free the Conqueror’s native land.” In short, they present the Battle of Normandy as the latest in an ongoing saga between France and England, one which began with conquest and war and ended with friendship and liberation. Kind of heartwarming when you think about it!
Later that same day, we visited this cemetery and paid our respects. Completed in 1952, this cemetery contains 4,144 Commonwealth burials of the Second World War, 338 of them unidentified. And unlike other cemeteries we visited, this one also has over 500 war graves belonging to other nationalities, the majority of which are German. This was an especially sobering sight to see after we visited the many British, Canadian and Commonwealth graves we paid our respects to.

Mulberry Harbor in 1944
Then, we reconvened with my father and headed off to the coast again. Our next stop was Arromanches and the Gold Beach Museum, where we were treated to the site of the artificial harbor that is still visible there today. Here, we grabbed some lunch, took some nice pics in front of the Allied and German vehicles and guns that are displayed there, and entered the museum to learn about the history of the beach and learn more about the massive feat of engineering that took place there 70 years ago.
Known as Mulberry Harbor, this artificial port was constructed by the British from 1942 to 1944 in order to assist the Allies in Operation Overlord. Basically, they understood that no army would be able to survive in Normandy for long without a great deal of supplies, which in turn would require the deep waters and heavy cranes of a port facility to park the freight ships and unload them. They also knew from the Dieppe Raid how difficult it would be to seize a heavily-defender harbor.
Arromanches and Mulberry Harbor as it appears today
Because of this, they set to work building a series of cement barriers which were then taken in sections across the English Channel and assembled off the coast of Arromanches. A series of tankers were also sunk in strategic positions around these “Mulberries”, forming an artificial breakwater with a series of pontoon causeways built within it. Once completed, Allied supply ships would sail into the protective harbor and unload along the causeways, sending tons of goods into the Normandy coast.
Had it not been for this harbor, the Allied invasion would surely have been doomed. Not only did the invasion require an endless stream of ammunition, food and fuel, it would be some twenty-four days before Allied forces would capture a port facility. This port was Cherbourg, which fell to American forces on the 30th of June, but which had been so thoroughly wrecked by the Germans occupants that it did not enter into even limited use until the middle of August.
Gold Beach Museum
All of this was explained in detail in the Gold Beach Museum, which contained detailed models of the harbor, amphibious landing craft, and countless bits of wartime artifacts. The multimedia presentation, which consists of viewers standing in a simulated amphibious craft and looking at the coastline on the dawn of June 6th, 1944. On the second floor, a short film also explains the harbor’s construction and the challenges in building and maintaining it.
Afterwards, we retired to the street again and tried desperately to find a public bathroom. My father and mother lamented the fact that during their last visit, one proved difficult to find then too. These and water fountains were both pretty rare in Arromanches, one has to wonder if there’s a connection! But having taken care of all that, we loaded back into the car and discussed our next destination. My father suggested that we check out a coastal battery that was still intact and not that far away, and we agreed.
German Flak 18 88mm cannon at Arromanches
Unfortunately for us, Betty was not the best at finding landmarks. And so, we had to drive for some along the coast and through our share of small towns before we found our destination. Luckily, some signs eventually pointed the way, and we made it the German coastal battery at Longues-sur-Mer. When we arrived, we noticed how the one battery, which had been hit during Battle of Normandy by an Allied ship, had a camera crew inside it. A tarp was lain over the collapsed roof, and the crew had a sign up saying “excavation in process”.
We couldn’t be sure exactly what they were doing, but we anticipated it was something for the History Channel or some such documentary stuff. Moving on to the batteries that were still intact, we began to explore inside. Though rusted, the guns were still there and aimed out to sea. They were also filled with gooey green water and algae, the result of seventy-plus years of rainwater collecting in them without interruption.
Coastal Battery at Longues-sur-Mer
There were two such batteries, both of which were relatively intact. Carla took some amazing pics of these, and then we proceeded to the very bluffs, where an intact observation bunker still sits. This bunker proved to be larger and less claustrophobic than the one at Juno Beach, and so I decided to do some deep exploration. This consisted of me going inside, despite my wife’s grievances, where I let my imagination loose and began pretending I was a commando raiding a German fortified position.
Unfortunately, when I moved to one side to dodge the imaginary bullets, I stepped in a hole filled with that same green, gooey water. Talk about an ugly soaker. As you can see, my wife was there to get it on camera. Yes, she wouldn’t follow me into the bunker and take some pictures of the preserved history, but she was more than willing to photograph my embarrassment. I love her dearly… After that, I stepped to the front end to look out the slat at the English Channel. I also waved hi to my folks who were standing at the bluff and looking out to sea. It was a mighty inspiring sight…
Then, it was back to the car, and off to the Bayeux War Cemetery for our last cemetery visit. After laying the last of our Canadian flag pins and paying our respects, we retired to the hotel to change (especially my socks!), and out for a dinner. This time around, we went to a restaurant near the Cathedral, where we enjoyed some interesting eats that consisted of gourmet burgers, pizza, and a buckwheat pancake with meat and veggies on it.
Back at the hotel, we also down a large bottle of Leffe Blonde together, and mercifully saved the Calvados for another night. I tell ya, that stuff could clean the grease off engine parts and isn’t too kind to stomach lining either! And when all that was said and done, we slept our final night at the Lion D’Or. The next day, we would be pushing off for Caen to do a little more touring of World War II sites, and then settling in to Chartres for the night.
Bayeux War Cemetery
I should also note that we took the opportunity to say goodbye to the cat that was living at the hotel. During our voyages, my folks kept mental list of the places that had animals, as they are avid cat lovers and have nine of them back home! Heck, my wife and I are crazy cat (and dog) people too, and we missed our cat Jasper terribly. So we were all pretty happy whenever and wherever there were household animals to keep us company. Alas, this would be the last time we ever saw another house creature…
Ah well. In any case, that was our time in Bayeux and environs. What came next was also pretty cool and informative, and involved the lion’s share of research that I did for our trip. More on that soon enough! Stay tuned…
So long, little black kitty! We hardly got to see ya…
Last month, the Hubble Space Telescope celebrated its 24th birthday. And in honor of this occasion, NASA has released a video entitled “Evaporating Peaks – Pillars in the Monkey Head Nebula”. This video, which showcases visible and infrared light views of a collection of pillars along one edge of the Monkey Head Nebula (also known as NGC 2174) is just the latest in series of simulations that attempt to recreate what it would be like to step into a major stellar body.
Like all nebulas, NGC 2174 is a star-forming region in which bright, newborn stars near the center of the nebula illuminate the surrounding gas, creating the brilliant images we see in the video. The radiation from these stars, combined with strong stellar winds, also erode areas of lower density gases, which in turn causes pockets of higher density gas to turn into visible formations. This is what leads to the creation of the pillars and peaks of gas that run along the inner edge of this roughly circular cloud.
The sequence begins with a view of the night sky near the constellation of Gemini and Orion and then zooms through observations from the Digitized Sky Survey 2 to reveal a Hubble Space Telescope visible light view of the top of this region of pillars.
For decades, scientists have dreamed of the day when cold fusion – and the clean, infinite energy it promises – could be made possible. And in recent years, many positive strides have been taken in that direction, to the point where scientists are now able to “break-even”. What this means is, it has become the norm for research labs to be able to produce as much energy from a cold fusion reaction as it takes in triggering that reaction in the first place.
And now, the world’s best fusion reactor – located in Oxfordshire, Engand – will become the first fusion power experiment to attempt to surpass it. This experiment, known as the Joint European Torus (JET), has held the world record for fusion reactor efficiency since 1997. If JET can reach break-even point, there’s a very good chance that the massive International Thermonuclear Experimental Reactor (ITER) currently being built in France will be able to finally achieve the dream of self-sustaining fusion.
Originally built in 1983, the JET project was conceived by the European Community (precursor to the EU) as a means of making fusion power a reality. After being unveiled the following year at a former Royal Navy airfield near Culham in Oxfordshire, with Queen Elizabeth II herself in attendance, experiments began on triggering a cold fusion reaction. By 1997, 16 megawatts of fusion power were produced from an input power of 24 megawatts, for a fusion energy gain factor of around 0.7.
Since that time, no one else has come close. The National Ignition Facility – the only other “large gain” fusion experiment on the planet, located in California – recently claimed to have broken the break-even point with their laser-powered process. However, these claims are apparently mitigated by the fact that their 500 terrawat process (that’s 500 trillion watts!) is highly inefficient when compared to what is being used in Europe.
Currently, there are two competing approaches for the artificial creation of nuclear fusion. Whereas the NIF uses “inertial confinement” – which uses lasers to create enough heat and pressure to trigger nuclear fusion – the JET project uses a process known as “magnetic confinement”. This process, where deuterium and tritium fuel are fused within a doughnut-shaped device (a tokamak) and the resulting thermal and electrical energy that is released provides power.
Of the two, magnetic confinement is usually considered a better prospect for the limitless production of clean energy, and this is the process the 500-megawatt ITER fusion reactor once its up and running. And while JET itself is a fairly low-power experiment (38 megawatts), it’s still very exciting because it’s essentially a small-scale prototype of the larger ITER. For instance, JET has been upgraded in the past few years with features that are part of the ITER design.
These include a wall of solid beryllium that can withstand being bombarded by ultra-high-energy neutrons and temperatures in excess of 200 million degrees. This is a key part of achieving a sustained fusion reaction, which requires that a wall is in place to bounce all the hot neutrons created by the fusion of deuterium and tritium back into the reaction, rather than letting them escape. With this new wall in place, the scientists at JET are preparing to pump up the reaction and pray that more energy is created.
Here’s hoping they are successful! As it stands, there are still many who feel that fusion is a pipe-dream, and not just because previous experiments that claimed success turned out to be hoaxes. With so much riding on humanity’s ability to find a clean, alternative energy source, the prospects of a breakthrough do seem like the stuff of dreams. I sincerely hope those dreams become a reality within my own lifetime…
Happy (early) May the Fourth everyone! This year, I thought I’d get on this fandom anniversary early by passing on some franchise news that was just released from Lucasfilm and Disney regarding the upcoming relaunch of the Star Wars franchise. After months of speculation, the cast for the upcoming Star Wars movie has finally been announced! The news came this past week in a post on StarWars.com, where companies spelt it out for all the fans who have been eagerly awaiting the news.
In addition to Mark Hamil, Harrison Ford and Carrie Fisher – who will receive top billing as Luke Skywalker, Han Solo and Princess Leia – Peter Mayhew, Anthony Daniels and Kenny Baker will also be reprising their roles as Chewbacca, C-3PO and R2-D2. Also, the movie will star several notable actors in new roles, including acting great Max von Sydow (The Tudors, Minority Report, Snow Falling on Cedars, Judge Dredd, Needful Things).
Also, Adam Driver (Girls, Lincoln), Oscar Isaac (Robin Hood, Sucker Punch, Drive), Andy Serkis (who brought Gollum to life in LOTR and the Hobbit franchises), Domhnall Gleeson (who played Bill Weasely in the Harry Potter series), and British television stars John Boyega and Daisy Ridley were announced, though has is not yet been announced what characters they will be playing. But since the upcoming movie will be taking place 30 years after Return of the Jedi, it’s fair to assume that the focus will be on these characters rather than on the original cast.
In a photo release this past Tuesday (seen below), director JJ Abrams is seen having a roundtable discussion with the cast at Pinewood Studios in the UK. Note the body of R2-D2 which sits unboxed behind them, having no doubt just been brought out of storage. JJ Abrams, identified by his spiky hair and glasses, can be seen sitting to the left of R2, with Harrison Ford to his right, Carrie Fisher two seats down, and Mark Hamil seated opposite to the far left of the photo.
When news of the cast was released, Abrams was quoted as saying:
We are so excited to finally share the cast of Star Wars: Episode VII. It is both thrilling and surreal to watch the beloved original cast and these brilliant new performers come together to bring this world to life, once again. We start shooting in a couple of weeks, and everyone is doing their best to make the fans proud.
This, the seventh film in the Star Wars franchise, and is slated for a December 18th, 2015, release. In addition to Abrams directing, he is also collaborating on the screenplay with Lawrence Kasdan, the man who co-wrote The Empire Strikes Back,Return of the Jedi and Raiders of the Lost Ark. Kathleen Kennedy, J.J. Abrams, and Bryan Burk are producing, and John Williams returns as the composer.
I think I speak for fans and geeks everywhere when I wish them all luck! Lord knows we could all use a really decent Star Wars sequel, especially when so many of us felt so utterly let down by the prequels! However, I think it is fair to say that Abrams and the rest should not be too concerned about what the fans and expect. If this latest installment is to be a success, it must not be overly aware of itself or its legacy. Such was part of what brought the prequels down in my estimation, and like everyone else, I just want to enjoy what comes next!
And we’re back with the third installment in the Williams’ Family Eurotrip 2014! As I’m sure I’ve said a few times now, this trip could hardly be summed up in a single post. Even with two posts – a sum total of 6000 words – I’ve managed to cover only the first five days. I might be able to cover the rest with an additional two, but I can’t promise a thing! Nevertheless, the next segment of our trip, which took us from Ypres to Dieppe, was a very interesting time.
Not only did we learn about some very interesting battles, which included a major victory for a Canada and a national tragedy, this part of our trip also served as a transitional point between the time was dedicated to World War I sites and those dedicated to World War II. In between all that, we also got to enjoy ourselves in the scenic Normandy countryside. Here’s how it all happened…
Monday, April 14th –The Vimy Memorial and Dieppe:
The Canadian National Vimy Memorial in the distance
Monday morning, we packed up, ate our last breakfast at the Albion Hotel, told them how much we enjoyed staying with them (my parents wrote a three page stellar review!), and prepared to head out again. This consisted of stopping by the market to get some sandwiches and bottles of water for the day, a necessity when you’re doing walking tours, and then see the Ypres Market, Cloth Museum and Cathedral one last time.
We then packed up the car and began driving for the French border, got on another toll highway, and drove through the sunny, canola flower-filled countryside. Eventually, we made it to The Vimy Monument, the last World War I site on our trip and the only stop along our way to Dieppe along the northern Normandy Coast. Long before we arrived, we could see the monument cresting the Ridge where it is located, not to mention the many slag heaps that mark the landscape.
The Battle of Vimy Ridge by Richard Jack
Again, a little background on this historic battle is in order. As part of the Battle of Arras (April 9th to May 16th, 1917), the Canadian assault on Vimy Ridge was part of an allied offensive against German positions around the town of Arras. The objective of the Canadian Corps was the high ground at the northernmost end of the front, an area which had remained in German hands despite previous offensives by both French and British forces.
By taking this position, the Canadians would ensure that the Germans would not be to observe the French and British advance further south, or direct artillery fire along the long axis of their advance. Supported by a creeping barrage, the Canadian attack would begin on April 9th and aimed to the fortified German positions along the ridge, as well as the strategic town of Thélus and Givenchy-en-Gohelle. Thanks to a combination of factors, the attack went off without a hitch.
Ultimately, the success of the assault was due to a combination of technical and tactical innovation, meticulous planning, powerful artillery support and extensive training. For weeks prior to the offensive, Canadian soldiers underwent training using models to represent the battlefield, and General’s Sir Julian Byng and Sir Arthur Currie made sure that every single soldier had a map of the ridge and knew exactly what would be needed of them.
The artillery support would rely on a relatively new tactic known as the creeping barrage, rather than the standard preparatory bombardment. In this latter case, artillery would shell the enemy line for days or weeks in advance of the attack, and then stop as the soldiers went “over the top” to charge the enemy positions. By contrast, a creeping barrage would begin shelling No Man’s Land to take out enemy barbed wire, and then crept forward to keep pace with the advance of the infantry.
In so doing, the Canadian’s artillery support was able to catch the German defenders as they were coming out of their dugouts to set up their machine guns and defenses. New methods and equipment were also used to triangulate the positions of the German artillery guns and take them out in advance of the attack. This way, the Germans had no reprieve from the bombardment, and no way to shell the Canadians as they moved up the ridge.
Within three days, the Canadians had secured the entire ridge and their objectives and forced the Germans to retreat to the Oppy–Méricourt line some five kilometers away. In addition, they took 4000 German prisoners and inflicted an estimated 20,000 killed or wounded, while suffering 3,598 dead and 7,004 wounded of their own. This too was a first, in that all previous offenses of the war involved the attacker sustaining far greater losses than the defender.

In addition to being a victory for the Canadian Corps and the first successful Allied offensive of the war, the success of this assault – much their performance at the Second Battle of Ypres – was a defining moment for the fledgling nation of Canada. As Brigadier-General Alexander Ross would famously say of the battle: ” . . . in those few minutes I witnessed the birth of a nation.” The triumph at Vimy also led to Byng’s promotion out of the Corps, and to his replacement by Arthur Currie — the first Canadian commander of the Corps.
Another outcome of this victory was the reputation earned by the Canadian Corps as being the army that could get things done where others could not. This reputation would further be tested in ensuing battles – the foremost of which was the Battle of Passchendaele – and The Hundred Days Offensive, the last one hundred days of the war when the Canadian Corps led the advance against the crumbling German lines through France and Belgium.
The four of us together at the top of the monument
Anyhoo, we arrived National Memorial in the late morning and were immediately struck by its sheer size. It’s two pylons, shown above, reach 30 meters into the sky, one bearing the maple leaf of Canada and the other the fleur-de-lis of France, symbolizing the unity and sacrifice of both countries. At the top of the two pylons is a grouping of figures known collectively as the Chorus, the senior of which represent the figures of Justice and Peace. The figures of Hope, Charity, Honour and Faith, Truth and Knowledge are located beneath (as seen in the image below).
Between the two pylons is the Spirit of Sacrifice, a young dying soldier is gazing upward in a crucifixion-like pose, having thrown his torch to a comrade who holds it aloft behind him. A lightly veiled reference to the poem In Flanders Fields by John McCrae, the torch is passed from one comrade to another in an effort to keep alive the memory of the war dead. Other figures around the monument include Sympathy of the Canadians for the Helpless, as represented by a standing man surrounded by kneeling people stricken by hunger and disease.
The Two Pylons of the Monument
Two more representations, named the Breaking of the Swords and cannons covered in laurel, further symbolize the monument’s commitment to peace. Facing east from the monument is the saddened figure of Canada Bereft, also known as Mother Canada, which personifies the young nation of Canada mourning her dead. The Mourning Parents, one male and one female, are reclining on either side of the western steps on the reverse side of the monument.
Inscribed around the outside wall of the monument are the names of the 11,285 Canadians killed in France, and whose final resting place is unknown. Some 60,000 Canadians died in the First World War, but even after all these years, 11,169 still remain unfound. To see these names listed in a continuous band, and knowing that they represent only a fraction of all those who died, really serves to drive home the terrible reality of the Great War and its brutality.
View from the monument, with sheep grazing in the distance
Looking upon the field that surrounded the monment, we were also quick to notice how the land was gnarled and lumpy, similar to what we had seen at the Beaumont-Hamel Newfoundland Memorial. Also like the Newfoundland Memorial, the land is surrounded by an electrified wire fence and warning signs that caution against venturing into it, and the only things allowed to walk freely there are grazing sheep. As someone who raised sheep as a child, my wife was naturally concerned about their safety.
However, the guides were quick to confirm that not a single sheep had died in the twenty years that they had been conducting tours. This was certainly a relief to hear, but it didn’t really detract from the reality of the war that this display drove home. As soon as the war ended, the farmers and their flocks returned; and over the course of the years, unexploded mines and munitions accounted for more than a few lives – human, bovine and ovine!
The Mourning Mother, and more sheep grazing in the distance
After scaling the steps of the monument, we began placing Canadian flag pins here and there to pay our respects. We also snapped some photos of the monument, the surrounding landscape, and of ourselves as a family standing on it. After this, we ventured to the far end of the site to see the Grange Subway – a preserved underground tunnel and stretch of trenches – and the site’s museum. On the way, we saw plenty more trenches, shell holes, and one massive crater that had clearly been left by a mine.
We reached the Grange Subway and booked a tour, and a kindly guide gathered us and about ten others and brought us inside. I can tell with you with no trace of shame that the place was pretty claustrophobic and I might have had some trouble if we hadn’t kept moving. Still, it was extremely impressive to see this tunnel that the Allies had dug during the course of the war. In addition to the walls carved from the chalk and flint that make up the ridge, the tunnel was replete with dugouts, side tunnels, officers messes, and message stations.
The preserved German trenches and mortar position
And of course, the whole place stunk of mold, wet stone and chalky residue. Our guide then took us back outside, to where the tunnel ended in a recreated section of Canadian trench that overlooked another massive crater. Here too, a mine had been exploded just short of the German front lines, which also had a section of preserved trench that showed us how well dug in and fortified their positions were. Unlike the Allied lines, the Germans had had time to pour concrete and build outposts and “pillboxes” to both observe and shoot from.
After the tour finished, we headed back to the museum to take one last look around and then eat our lunch. On the way, we found some additional artifacts, which included a piece of chalk and flint (pieces of the Ridge) and a piece of what appeared to be ceramic with a letter B stamped on it. From its size, contoured shape, and the way it was marked, we could only guess what it was. But the prevalent theory was that it might have been an officers china cup.
The cliffs of Dieppe
And then it was to Dieppe for the night! Despite some problems with our GPS navigator – whom we named Betty since of the female voice – we made it to the hotel down by the beach. Kudos to my mother for her good job of booking the place! After getting into our rooms, we had a nice beer down at the hotel bar, and then decided to get in a beach walk before dinner. Now I should note that this walk, despite the lovely sand and stone beach, was not strictly for enjoyment. You see, a lot happened on that beach some seventy-years ago…
In 1942, this region of France was still firmly in the hands of Nazi Germany. In addition, the Germans were still occupying much of Russia and had the British tangled up in North Africa. The United States had just entered the war and was facing a fight on two fronts – Europe and the Pacific. And with Russian losses numbering in the millions, a great deal of pressure was on the Allies to open a “Second Front” on the Continent again.
To test the German’s coastal defenses, and evaluate the likelihood of making a successful amphibious assault, the Allies began making plans for a raid against the Atlantic coast. In what would come to be known as Operation Jubilee, a force of 6,000 infantrymen – predominantly Canadian and supported by a Canadian Armoured regiment and the Royal Navy and Air Force – the plan was to seize a port town, destroy the military facilities, and then evacuate before a German counter-attack could arrive.
Commander by Lord Louis Mountbatten, a British Admiral and 1st Earl of Burma, the attack was also intended to show that such an assault – which was the first step in liberating Europe – could be done. On August 9th at 5:00 am, the assault began as Canadian and British troops, as well as 100 US Rangers and Free French Commandos, began landing on the beach. By 10:50 a.m., the Allied commanders were forced to call a retreat.
The Dieppe Raid, or the Battle of Dieppe, would go down as one of the greatest blunders in military history, and is considered a national tragedy here in Canada. After less than 10 hours since the first landings, the last of the Allied troops had either killed, evacuated, or left behind and captured by the Germans. All told, a total of 3,623 of the 6,086 men who made it ashore were either killed, wounded, or captured, and demonstrated that the Allies could not hope to liberate Europe for some time.
There are several reasons why the raid was a failure. For starters, Allied fire support was grossly inadequate and failed to take out the German defenses. As a result, the advancing infantry was quickly trapped by machine gun fire, mortars and coastal batteries that sighted them as they tried to run up the rocky coastline. The Royal Air Force also failed to lure the Luftwaffe into open battle, and took some heavy losses themselves (96 aircraft compared to 48 lost by the Germans).
Dieppe Raid by Charles Comfort
What’s more, the operation was repeatedly downsized, reducing its troop strength several times before it was approved. The Allied commanders, most notably Mountbatten, claimed that this would not be a problem as the attacking force would have the element of surprise. However, this was immediately squandered due to the British government openly talking about the raid for weeks before it happened. In short, the Germans knew they were coming.
While a more recent interpretation of the raid – which claims it was done as part of a clandestine operation to seize a four-rotor Enigma machine – have reevaluated it’s purpose, the outcome of the operation was anything but successful. In the end, the only good to come of it lay in the fact that it taught the Allies precisely what not to do when staging a coastal assault. These lessons greatly influenced their preparations when drafting Operation Torch (the landings in North Africa) and Operation Overlord (the D-Day landings in Normandy).

While walking the beach, my father and I noted the way that it sloped upward and was covered in r0und stones. It wasn’t hard to see at all how tanks would be immobilized by these once they got stuck in their treads. What’s more, the thought of charging up the inclined beach with a rifle and sixty pounds on gear on our backs seemed like absolute folly. Especially if we knew there were machine guns and cannons aimed at us.
Such was our attempt to understand what it must have been like for the young Canucks, Brits, French and Americans who were expected to capture this town. And when we mounted the top near the breakwater, we came to a couple of monuments dedicated to the soldiers who fell on the morning of the 19th of August. This included the Red Beach Monument, which honors the members of the Essex and Kent Scottish Regiment, and all those who fell on the eastern sector of the beach.
Financed by members of the Windsor community in Ontario, this monument was erected at town’s edge overlooking the beach and was carved from black granite with the cutout of a maple leaf in it. This cutout is aligned so that when the sun shines at 1 p.m. on Aug. 19 — the exact hour that the regiment stormed the beach — it will cast a perfect shadow of a maple leaf on the ground below. Farther down, we found another monuments commemorating the units that fell in other sectors of the beach. At both, we laid a Canadian flag pin and paid our respects.
Then it was back to the hotel for some much needed grub and some sleep. It had been quite a long day, as you can no doubt tell from the lengthy recap. And we certainly needed plenty of rest, because what came on the next day would test us both physically and emotionally. But more on that later, as it deserves a separate post for sure. Thanks for reading, more to follow, and stay tuned!
For over two years now, Elon Musk and his private space company (SpaceX) have been working towards the creation of a reusable rocket system. Known as the Falcon 9 Reusable Development Vehicle (F9R Dev) – or “Grasshopper” – this system may prove to be the greatest development in space travel since the invention of the multistage rocket. After multiple tests that reached greater and greater altitudes, the latest attempt at a takeoff and soft landing took place this past month.
Timed to coincide with SpaceX’s launch to the International Space Station (which took place on Friday April, 18th) the landing was apparently a success. Several days after the launch, Elon Musk tweeted that the “[d]ata upload from tracking plane shows landing in Atlantic was good!” This update came on April 22nd, and as of yet, no definitive data of whether the first stage landed correctly, or whether it was still in one piece by the time the recovery boats got to it.
Presumably SpaceX will provide another update in due course. In the meantime, they took the opportunity to release a rather awesome video of what the Falcon 9 Reusable should look like when successfully performing a vertical takeoff and vertical landing (VTVL). The video has accumulated an astonishing 3,598,143 views in the last two weeks, which is indicative of the level of interest this project and its impications have garnered over the past few years.
Meanwhile, the resupply mission went off without a hitch. Officially designated as CRS-3, this mission was even more significant due to the fact that its Falcon 9 launch vehicle featured the same retractable landing legs and the ability to soft land as the Grasshopper test rocket. However, in the case of the ISS mission, it was the first time where a Falcon 9 was tested in a real-world scenario where the rocket would return to Earth after reaching Low Earth Orbit (LEO).
Though the rocket was successfully picked up by the ISS, the jury is still out on whether or not the soft landing was a success or not. To minimize any risk, the first stage of the Falcon 9 attempted to “soft land” in the Atlantic. Unfortunately, according to Elon Musk, due to “13- to 20-foot waves… It’s unlikely that the rocket was able to splash down successfully.” Using telemetry data gathered from a SpaceX spotter plane, it appears that everything else went to plan, though.
Because of the rough seas, though, the retrieval boats couldn’t make it to the landing site, and thus the rocket is unlikely to be recovered. In the meantime, SpaceX will spend the following days and weeks analyzing more detailed data from the launch, and then update the Falcon 9 design and launch protocol accordingly. However, it is clear at this point that these latest tests are not being considered a failure, or reason to cease in their efforts.
As Musk himself explained in a series of public statements and interviews after the launch:
I would consider it a success in the sense that we were able to control the boost stage to a zero roll rate, which is previously what has destroyed the stage — an uncontrolled roll…I think we’re really starting to connect the dots of what’s needed [to bring the rocket back to the launch site]. I think that we’ve got a decent chance of bringing a stage back this year, which would be wonderful.
Considering the benefits of cheap, reusable rockets, and all the things they will make possible – space-based solar power, the construction of a Moon settlement, missions to Mars, the construction of a Space Elevator – there’s simply no way that a single unsuccessful rocket recovery will deter them. In the meantime, be sure to check out this video of what a successful Falcon 9 VTVL test looks like. Hopefully, we’ll be seeing a real-world example of this happening soon:
Though I am a week late in expressing this sentiment, I feel I must acknowledge this rather interesting of events. As it stands, this past April 22nd was the sixty-first anniversary of the molecular structure of DNA being revealed to the world. What began as a publication in the magazine Nature has now become emblematic of the programming language of life, and our understanding of DNA has grown by leaps and bounds over the past six decades.
To commemorate such an important landmark in the history of humanity, a look back at some of the more recent developments in the field of genetic research would seem to be in order. For example, it was on April 22nd of this year that a rather interesting study was published in the Proceedings of the National Academy of Sciences. The lead on this study was none other than Svante Pääbo – the world’s foremost expert in Neanderthal genetics.
Based on the genomes of three neanderthals that were found in disparate locations in Eurasia, Pääbo and his colleagues have concluded that the genetic diversity in Neanderthals is significantly less when compared to present-day Homo sapiens. It also appears as if the Neanderthal populations were relatively isolated and tiny, so gene flow was extremely limited for these groups. In short, our homonid cousins didn’t get around and interbreed quite as much as we’ve done, which may shed some light on their disappearance.
On the very same day, an article was published in the Proceedings of the Royal Society B that proposed that skin cancer from the sun’s damaging UV rays was actually a driving force in the national selection for dark skin in early humans. In the article, Mel Greaves delivers a compelling argument that the deadliness of skin cancer in young albino children in Africa and Central America demonstrates just how vital it was for early humans to develop dark skin.
And on April 25th, National Geographic and Family Tree DNA teamed up to announce the release of a brand new version of the human Y-DNA tree. This new tree of Y chromosome mutations has over 1,200 branches — almost double the number of branches that the Genographic Project was displaying before. With this much refinement, it’s now even easier to track the historical migrations of your distant ancestors.
To celebrate this monumental roll-out, Family Tree DNA offered a 20% discount on the 37-marker Y-DNA test and all individual Y-DNA SNP (single-nucleotide polymorphism) tests, an offer which sadly expired on April 27th. However, interested parties can still have this cutting-edge anthropological genetic test performed for $200. And it’s something to keep in mind for next year certainly. What better way to celebrate DNA day than to have a full genetic profile of yourself made?
And let’s not forget, 2012 was also the year that the Encyclopedia of DNA Elements (ENCODE) Consortium – an international collaboration of research groups funded by the National Human Genome Research Institute (NHGRI) – released the world’s most complete report on the human genome to date. Unlike the Human Genome Project, which released the first catalog of human DNA back in 2003, ENCODE was not only able to catalog the human genome’s various parts, but also what those components actually do.
Among the initiative’s many findings was that so-called “junk DNA” – outlier DNA sequences that do not encode for protein sequences – are not junk at all, and are in fact responsible for such things as gene regulation, disease onset, and even human height. As I’ve said before, these findings will go a long way towards developing gene therapy, biotechnology that seeks to create artificial DNA and self-assembling structures, and even cloning.
Yes, it’s an exciting time for the field of DNA research, and not just because of the many doors its likely to open. Beyond medical and bioresearch, it helps us to understand of ourselves as a species, our collective origins, and may perhaps help us to see just how interconnected we all truly are. For centuries now, a great many evils and prejudices have been committed in the name of “racial superiority” or racial differences.
Armed with this new knowledge, we might just come to realize that this great organism known as humanity is all fruit of the same tree.
One of the greatest benefits of additive manufacturing (aka. 3-D printing) is the way it is making everything – from finished goods to electronic devices – cheaper and more accessible. Modern medicine is also a beneficiary of this field of technology, with new tests and possibilities being produced all the time. In recent weeks, researchers have announced ways in which it might even help lead to a cure for cancer and combat one of the greatest health epidemics of the world.
When it comes to testing cancer drugs, researchers rely on the traditional two-dimensional method of seeing how they work on cancer cells within the confines of a Petri dish. If the drug works well, they move onto the next stage where they see how the drug deals with 3-D tumors in animals. If that goes well, then, finally, researchers start clinical trials on humans. But if it were possible to test these drugs in a 3-D scenario right away, time and money could be saved and effective treatments made available sooner.
And now, thanks to a team led by Dr. Wei Sun of Philadelphia’s Drexel University, this may be possible. Using the techniques of 3-D printing and biofabrication, the research team was able to manufacture tumors by squirting out a mixture of cancerous and healthy biomaterial, dollop by dollop, and create a three-dimensional replica of a living tumor. Because of this, the field of cancer research could be revolutionized.
According to Sun, there’s just as huge a disconnect between what works in two versus three dimensions as there is between what works in animals versus humans. These disconnects are what make developing new cancer drugs so time consuming and expensive. You can’t just rely on a formula when switching to each new environment, testing takes time, results must be documented along the way, and adjustments made at every step.
With Sun’s 3-D printing technology, a living tumor can be printed just as easily as cancer cells grow in a Petri dish. The machinery used is capable of printing with extraordinarily high resolution, which allows cells to be placed with incredible precision. The average cell is 20 microns, where as Sun’s system can place individual cells within two to three microns. That means Sun can print out extraordinarily specific, spheroid-shaped tumors in a multitude of different shapes and sizes.
But testing cancer drugs more easily is only one of the many uses of Sun’s technology. Since each tumor is different, there’s the possibility that the technology could be used to simulate individual patients’ cancers in the lab and see which drugs work most effectively on them. What’s more, Dr. Sun indicates that cancer testing is really just the beginning:
Doctors want to be able to print tissue, to make organ on the cheap. This kind of technology is what will make that happen. In 10 years, every lab and hospital will have a 3-D printing machine that can print living cells.
On another front, 3-D printing technology is offering new possibilities in the treatment of diabetes. Often referred to as a “rich man’s disease”, this condition is actually very prevalent in the developing world where nutrition is often poor and exercise habits are not always up to snuff. To make matters worse, in these parts of the world, the disease is not considered a serious health problem and proper means and facilities are not always available.
Enter the Reach, a cheap new diabetes test developed by a group of students from the Schulich School of Business at York University in Toronto. Relying on 3-D printing technology, the device is aimed at urban “slum-dwellers” who may be threatened with diabetes, but very likely haven’t been checked for it. It’s one of six finalists for this year’s Hult Prize, which challenges students to create social good enterprises.
This year’s goal, which was set by Bill Clinton, is to reduce rates of non-communicable diseases among the urban poor. As part of their Social Enterprise Challenge, the 2014 Hult Prize is intended to address the challenge of building “a social health care enterprise that serves the needs of 25 million slum dwellers suffering from chronic diseases by 2019.” And as Dhaman Rakhra, one of the students on the York research team, put it:
We saw that diabetes is growing at the fastest rate among the slum population. It is also a disease that can be addressed, and where you can have an immediate impact. A lot of it is about a lifestyle change, if it’s detected early.
Roughly the size of a postage stamp, the Reach is similar to a home pregnancy test, in that it tests a patient’s urine. If someone’s urine has a certain level of glucose in it – indicating propensity for diabetes – the test changes color. Most importantly of all, the test can be printing out on a normal 3-D printer, making it unbelievably cheap (just two cents a pop!) The students plan to distribute the Square using the Avon business model, where local people will sell on the enterprise’s behalf.
The Schulich students, who are all undergraduates, plan to refine the idea over the summer, first spending time with a Hult accelerator in Cambridge, Massachusetts, then during a month-long pilot test at a large slum in Mumbai. If they should win the Hult Prize, they will be awarded one million dollars to further develop, refine and finance it. But as Rakhra claimed, the real fun comes in the form of bright minds coming together to come up with solutions to modern issues:
It’s exciting to really show that young people really can make a difference by creating a social enterprise that’s self-sustaining. It’s not something that many young business students really think about as a career path. But it’s definitely something we hope to influence.
The on-site manufacturing of cheap, effective drugs, prosthetics, and medical devices are undoubtedly one of the most exciting aspect of the revolution taking place with additive manufacturing. For starters, it is creating more cost effective ways to address health problems, which is a saving grace for patients and medical systems that are strapped for cash.. At the same time, it shows the potential that new technologies have to address social and economic inequality, rather than perpetuating it.
And I’m back, with the second installment of what the family and I did on our recent trip to Europe. Like I said before, there is a lot to cover and I couldn’t possibly deal with it all in one post. And after we flew in and did our first day of driving and visiting the Beaumont-Hamel Memorial Park, we drove to the first town where we would be rooming on our trip. This is the historic town of Ypres, Belgium (pronounced either as Eep, or Ee-pairs, depending on whether its spoken in French or Flemish).
And arguably, some of our best times and experiences were here. Not only were the townspeople incredibly friendly, the food and accommodations good, and the local culture something to behold, the way the war is commemorated and those who fell honored is truly astounding. For those of us who only mourn the losses of the Great War and observe the lessons obtained therein once a year, it truly boggles the mind. But I digress, here’s what happened…
Saturday, April. 12th – Sunday, April. 13th –
The Ypres Experience: As I said last time, Ypres was our first stop after two days of ongoing travel and very little sleep. And after we rested up and showered, we had some pretty full days experiencing the town and the many cemeteries, memorials and museums that dot the landscape. It was also while touring Flemish city and the surrounding countryside that we made what was perhaps the biggest find of our trip – pieces of shrapnel from the war!
Now for those unfamiliar, this ancient town is the municipal capitol of West Flanders that dates back to before the time of the Roman conquest. During the Middle Ages, it was renowned for its cloth and textile industry, and was even mentioned in the Canterbury Tales due to its extensive trade with England. However, the town is best known due to the fact that it was contested ground for three separate battles during the Great War.
During the First Battle of Ypres, which took place from October 19th to November 22nd, the Allies retook the town from the Germans, who had captured it during their initial advance through Belgium. The Second Battle of Ypres – April 22nd and May 25th, 1915 – was where the German army attempted to break the stalemate in the west by using poisonous gas for the first time. It was at this time, as already mentioned, that the 1st Canadian Infantry Division distinguished itself by standing their ground and beating back the German assault.
To put this in perspective, the Canadians were an untested unit that had recently arrived in Flanders to witness the terrible carnage that had become of the war. When the Germans unleashed the poisonous clouds of chlorine gas into the city, these soldiers did not yet have gas masks (or proper helmets) and thousands of men began to die. The French and British lines crumbled under the onslaught; but at St. Julien, where the Canadian Division was stationed, an inventive Canadian officer came up with a novel idea that saved them from death and retreat.
Remembering a lesson from chemistry class, he ordered his men to urinate on rags and apply them to their faces. Knowing that ammonia, which urine contains, neutralizes chlorine by turning it into harmless ammonium chloride crystals, the Canadian soldiers simply breathed naturally through their urine-soaked rags and waited for the gas to roll over them. When it did, they took up their positions and were there to meet to the Germans when they assaulted.
Because of this, the German attack failed, and led Sir George Perley (Canada’s High Commissioner in Britain) to state that the “saved the situation”. British Lieutenant General Smith-Dorrien followed this up with the conciliatory statement that had it not been for the Canadian troop’s gallantry, the initial German breakout that took place early in the battle “might well have been converted into a serious defeat for our troops.” All told, this gallantry came at a terrible cost – with some 5,975 casualties, of whom roughly 1,000 were killed.
The ruins of Ypres in 1919
The battle raged on for many more months, with some 100,000 men being killed, captured or wounded before the end. However, it was The Third Battle of Ypres – also known as the Battle of Passchendaele (July 21st – November 6th, 1917) that was the best-known and bloodiest of the war. After months of fighting, this battle resulted in nearly half a million casualties on all sides, and only a few miles of ground were won by the Allied forces. During the course of the war, the town was also all but obliterated by the artillery fire.
These events are commemorated on a daily basis by the town’s people, and the names of those who fell are inscribed on the Mennin Gate, which sits at the east end of the old city. But I’m getting ahead of myself here! Before I can cover all the historic sites we took during the course of our stay, I should mention the hotel where we slept, which was none other than the Hotel Albion. In addition to being located in a building in the old city, the rooms were spacious and beds king-size, which came in handy upon arrival!
The old city, as it is today
After waking up on Saturday and getting some much-needed shower time, we enjoyed the hotel’s traditional Belgian breakfast spread. This consisted of hard boiled eggs, sliced meats, cheeses, assorted breads (baguette, croissants, pain au chocolat, etc.), jams, and of course some really good coffee. After eating and drinking our fill, we set out about town, and our first stop was the Cathedral located next to our hotel. After appreciating the centuries-old architecture, we lit some candles and headed for the center of the old town.
Next up was the bookshop my parents had seen on their last visit and wanted to see again, a place called The British Grenadier, which specializes in war memorabilia, books, and historic keepsakes. The guy who runs its, a man by the name of Steve Douglas, just happens to hail from Waterloo, Ontario, where my parents lived and studied for many years before I was born. While there, we chatted with Steve (a rather stoic figure who nevertheless seemed to remember meeting my folks) bought some postcards, poppies, a hat for myself, and marveled at his large collection of wartime artifacts and commemorative goods.
The Ypres Market, with the spires of the Cloth Museum (left) and Cathedral (right) in the distance
After that, it was off to the town market which, since it was a Saturday, was out in full force! Basically, the center of the old town was filled with vendors of every kind peddling snacks, clothing, shoes, fresh meats, fish, cheeses, and even some livestock. After walking through this crush of human activity, we came upon the Cloth Museum. This massively long medieval structure was the heart of the city’s linen and textile trade, and was made incredibly long so that bolts of cloth could be unwound completely to check for authenticity.
After being almost completely destroyed in the war, the town rebuilt it and renamed it the In Flanders Fields Museum, in honor of the John McCrae poem of the same name. Once inside, we got to see just how amazing it was. The entire museum is kept dark, somber music plays in the background, and multimedia displays show reenactments of various aspects of the war. There are also photographs, maps, and artifacts as far as the eye can see. And every visitor is asked to make an account for themselves in the museum database and given a poppy-shaped wrist band that is programmed to identify you.
These identifying wristbands not only allow you to get in and out, they also let you access to terminals and have what they call “Personal Encounters”. Basically, this amounts to you accessing various terminals throughout the library and being given information on people who served in the war. Once obtained and compiled to your account, you can request that the museum email it all to you, which I naturally chose to do. The names of my Personal Encounters were Elsbeth Schragmuller, William Flack, and Mike Mountainhorse.
Click here to see the museum certificate that contains their bios, and be sure to check out the museum’s website for more information on who they are and what they do. After exiting the museum, we had some lunch from a sausage cart (foot longs with fried onions and some interesting choices of sauce) and headed over to the Cathedral located next door, which was also destroyed during the war. Here, we watched as the local choir was warming up for a big show and lit some more candles.
The Mennin Gate, as seen from the street
Then it was a quick nap back at the hotel to combat the lingering effects of jet lag followed by some dinner in the market at a place known as Antonio Vivaldis, which my parents had been to the night before. We drank Leffe Blonde, which is available here in Canada but is something of the beer of choice in Flanders. Last time my folks came back, they made it quite clear that this and Kronenbourg (also a local favorite) were now their beers of choice!
Then, we walked down to the Mennin Gate to take in the Saturday night ceremony that honors all the Commonwealth soldiers who died during the Great War. This great archway, which you can see above, has the names of every single soldier inscribed on it, and ceremonies to honor their sacrifice take place every night. Yes, you read that right. EVERY SINGLE NIGHT the people of the town gather at the gate, the local choir sings songs, the Mayor comes out to speak, The Last Post is played, and wreaths are lain.
Inside the Mennin Gate. Note the names inscribed on the walls
And even though this is a daily occurrence, Saturday is a special night, when the largest and most elaborate ceremony takes place. I should also note that in Ypres, the poppy – as a symbol of remembrance – is worn year round and can be seen just about everywhere one looks. To put that in perspective for us foreign folks, its like having Remembrance Day (Veterans Day, Poppy Day, Armistice Day) every day. None of this once-a-year on November 11th stuff.
We then walked the wall, which overlooks the moat that circles the old part of town and also has its share of commemorative plaques and statues. I tell you, every corner of the town pays homage to its long and rich history, and even a short walk can reveal all kinds of interesting things! And that was Saturday. Sunday morning, we woke up, had another sumptuous breakfast, and headed out of town to visit all the Commonwealth Cemeteries we could find, as well as a German one.
Yorkshire Trench
We began with the Concrete Farm Cemetery, a smaller Commonwealth cemetery located outside of town. After stopping here to pay our respects to these soldiers and lay some Canadian flag pins on the Canadian graves, we continued on to Yorkshire Trench. This trench and the park that now features it was first uncovered in 1992 by a group of amateur archaeologists known as “The Diggers”, people who are dedicated to finding the bodies of the fallen that were never retrieved and giving them a proper burial.
Between 1998 and 2000 they spent many hours digging and examining the trench, which also had tunnelled dugouts. At the time major construction work for new buildings in Ypres’ northern industrial zone was also being carried out. Hence, like so many other trenches, graves and unexploded munitions, this small piece of the Ypres Salient was discovered entirely by accident. And in addition to many artifacts “The Diggers” discovered, the remains of 155 First World War soldiers were uncovered – the bodies of British, French and German that were lost in battle and never recovered for seventy years.
Outside Langemark Cemetery
Then, it was off to Langemark, the German cemetery that was set aside by the Belgian government. Compared to the Commonwealth grave sites, this cemetery was very somber. Pruned trees surrounded the outer edge of it, the concrete bunkers that had served as dugouts during the war were now filled with leaves and detritus, and the many, many German fallen were interred four to a grave marker. And near the front gate, a single, mass grave known as the “Comrades Grave” contains the bodies of no less than 24,917 servicemen, including the flying ace Werner Voss.
Inside the gatehouse, the names of the more than 44,000 soldiers who died during the many battles of Ypres are etched into the wooden walls. Of particular interest were the names of the 3000 German students who fell while crossing the field that next to the cemetery. Legend has it that these German students walked arm in arm and sang “Deutschland, Deutschland über alles” as they charged across the battlefield, and to their deaths. Yet another reminder of the futility and folly that characterized the Great War for all sides.
My father examining the map of the Ypres Salient inside the cemetery’s gatehouse
It was also here that my father and I, while searching in the farmers field next to the cemetery, came across our most important keepsakes from our trip. As he knew from his previous visits to the countryside, the fields that once made up the Ypres Salient constantly turn up pieces of shrapnel, spent shell casings, and even unexploded munitions when the weather changes. In this last case, farmers come across these shells when the winter weather causes the ground to freeze and the soil pushes these shells to the surface. Typically, these are then removed and placed by the side of the road to await for bomb disposal crews who take them away and detonate them.
But in the case of shrapnel, bullet casings and other pieces of wartime history, one doesn’t have to look very hard to uncover them. Simply walk into a farmer’s field or a dig anywhere in the region, and odds are good you will find something. We had a hard time searching the nearby field since a tractor was out turning the soil with some rather large blades. Still, we managed to find several fragments of exploded shells at the edge of the field, and after only a few minutes of looking.
The shell and bullet fragments we found by Langemark Cemetery
The grizzly significance of this was not lost on us: that so many artillery shells and bullets were fired in this region over a century ago that bits and pieces are still being found, and it took us only a few minutes of searching in a tiny parcel of land to find some. And of the four pieces that we pulled out of the ground, the first and largest was certainly the most recognizable. Roughly three inches long, an inch and a half wide, and over half an inch in thickness, this hunk of rusted metal had a curvature and striations on one side that indicated that it was an artillery shell.
We guessed that it was British, and given its size, it most likely came from a 18-pounder field gun. The other two, much smaller, looked to be large bullet fragments, in that they were cored in the center and not that big. Still, they appeared rather large for a standard rifle or machinegun, so it’s possible they were from a heavy machine gun. Of course, its difficult to say since 100 years of caked-on dirt, rust, and wear can kind of obscure a fragments true size and dimensions.
The St. Julien monument
After that, it was on to St. Julien, the town outside of Ypres where the monument to the Canadian soldiers who held their ground during the first gas attack is located. While admiring the monument, my father spotted a fellow Canuck, who was identifiable from his Hamilton Tiger Cats jacket (his hometown). After spotting him, my father went over and promptly chatted him up. He does that a lot! And then, it was off to our last stop for the day – the Tyne Cot Commonwealth Cemetery.
This cemetery, which is the final resting place of 11,954 soldiers who died in the Ypres Salient during the Great War, is the largest Commonwealth cemetery in the world. Of these, some 8,367 are unidentified, and their headstones are inscribed with the words “Known unto God”. In addition to these graves, there’s also the four memorial that honor the roughly 90,000 British and Commonwealth soldiers who died here – most of whom were never found or properly identified – with the names of each inscribed on the walls.
Tyne Cot Cemetery
We started with the Visitor’s Center, a small and somber museum, before working our way into the cemetery proper. Inside and out, we heard a recording playing where the names of all those who fell in the Ypres Salient were spoken on a loop. To give you some sense of how many men that was, the recording takes a full FIFTEEN YEARS to get through the entire list. Yes, more men fell in this region within the space of four years than can be even be named in that same amount of time. Unbelievable!
Once outside, we walked amongst the headstones and looked for the telltale Maple Leaf that indicated that it was a Canadian soldier who had been buried there. On these, we placed Canada flag pins and thanked them for their service. I can tell you, being surrounded by so much death, and knowing the sheer scale of it, was quite overwhelming. After we had run out of pins and written our names in the visitors book, we hopped back in the car and drove back into town.
My parents and I looking through the headstones
The rest of the day was spent separately, with my folks having dinner on their own and Carla and I going out for a run. We spent about an hour running around the wall that encircles the old city, visited the Cathedral again, found a place to eat (a nice bistro called “The Goose”), and gorged ourselves on curried chicken, chicken wings, and salad, all of which was washed down by some lovely Belgian Trappist beers and a tall Pilsner. It was a nice, gentle way to conclude a day characterized by sober reflection and somber reminders.
And then, the quiet sleep, knowing that it was our last night in Ypres and we would be leaving for the Normandy coast, and visiting the Vimy War Monument, the next day. It would be the day when we made our final visit to a monument dedicated to those who served and died in the Great War, and the first day of visiting World War II monuments, museums, and cemeteries. And to do it justice, I am going to need to give it it’s own post!
Until next time, thanks for reading, and always remember how fortunate we are to live in a world where total war is a thing of the past. May we never forget, and never be forced to repeat the mistakes of the past!
A little over two years ago, a tiny piece of code was introduced to the internet that contained a bug. This bug was known as Heartbleed, and in the two years it has taken for the world to recognize its existence, it has caused quite a few headaches. In addition to allowing cybercriminals to steal passwords and usernames from Yahoo, it has also allowed people to steal from online bank accounts, infiltrate governments institutions (such as Revenue Canada), and generally undermine confidence in the internet.
First off, Heartbleed is not a virus or a type of malware in the traditional sense, though it can be exploited by malware and cybercriminals to achieve similar results. Basically, it is a security bug or programming error in popular versions of OpenSSL, a software code that encrypts and protects the privacy of your password, banking information and any other sensitive data you provide in the course of checking your email or doing a little online banking.
What’s interesting about the bug, which is named for the “heartbeat” part of the code that it affects, is that it is not a virus or piece of malware in the traditional sense. What it does is allow people the ability to read the memory of systems that are protected by the bug-affected code, which accounts for two-thirds of the internet. That way, cybercriminals can get the keys they need to decode and read the encrypted data they want.
Several institutions have also come forward in that time to declare that they were subject to attack. For instance, The Canada Revenue Agency that they were accessed through the exploit of the bug during a 6-hour period on April 8th and reported the theft of Social Insurance Numbers belonging to 900 taxpayers. When the attack was discovered, the agency shut down its web site and extended the taxpayer filing deadline from April 30 to May 5.
Another consequence of the bug is the impetus it has given to conspiracy theorists who believe it may be part of a government-sanctioned ploy. Given recent revelations about the NSA’s extensive efforts to eavesdrop on internet activity and engage in cyberwarfare, this is hardly a surprise. Nor would it be the first time, as anyone who recalls the case made for the NIST SP800-90 Dual Ec Prng program – a pseudorandom number generator is used extensively in cryptography – acting as a “backdoor” for the NSA to exploit.
According to documents the paper obtained from Snowden, GCHQ had specifically been working to develop ways into the encrypted traffic of Google, Yahoo, Facebook, and Hotmail to decrypt traffic in near-real time; and in 2010, there was documentation that suggested that they might have succeeded. Although this was two years before the Heartbleed vulnerability existed, it does serve to highlight the agency’s efforts to get at encrypted traffic.
Though security vulnerabilities come and go, this one is deemed catastrophic because it’s at the core of SSL, the encryption protocol trusted by so many to protect their data. And beyond abuse by government sources, the bug is also worrisome because it could possibly be used by hackers to steal usernames and passwords for sensitive services like banking, ecommerce, and email. In short, it empowers individual troublemakers everywhere by ensuring that the locks on our information can be exploited by anyone who knows how to do it.
Regardless, Heartbleed does point to a much larger problem with the design of the internet. Some of its most important pieces are controlled by just a handful of people, many of whom aren’t paid well — or aren’t paid at all. In short, Heartbleed has shown that more oversight is needed to protect the internet’s underlying infrastructure. And the sad truth is that open source software — which underpins vast swathes of the net — has a serious sustainability problem.
Typically, projects start when developers need to fix a particular problem; and when they open source their solution, it’s instantly available to everyone. If the problem they address is common, the software can become wildly popular overnight. As a result, some projects never get the full attention from developers they deserve. Steve Marquess, one of the OpenSSL foundation’s partners, believes that part of the problem is that whereas people can see and touch their web browsers and Linux, they are out of touch with the cryptographic library.
When news of the cast was released, Abrams was quoted as saying:
Ultimately, the success of the assault was due to a combination of technical and tactical innovation, meticulous planning, powerful artillery support and extensive training. For weeks prior to the offensive, Canadian soldiers underwent training using models to represent the battlefield, and General’s Sir Julian Byng and Sir Arthur Currie made sure that every single soldier had a map of the ridge and knew exactly what would be needed of them.
In so doing, the Canadian’s artillery support was able to catch the German defenders as they were coming out of their dugouts to set up their machine guns and defenses. New methods and equipment were also used to triangulate the positions of the German artillery guns and take them out in advance of the attack. This way, the Germans had no reprieve from the bombardment, and no way to shell the Canadians as they moved up the ridge.
Presumably SpaceX will provide another update in due course. In the meantime, they took the opportunity to release a rather awesome video of 
As Musk himself explained in a series of public statements and interviews after the launch:
These identifying wristbands not only allow you to get in and out, they also let you access to terminals and have what they call “Personal Encounters”. Basically, this amounts to you accessing various terminals throughout the library and being given information on people who served in the war. Once obtained and compiled to your account, you can request that the museum email it all to you, which I naturally chose to do. The names of my Personal Encounters were Elsbeth Schragmuller, William Flack, and Mike Mountainhorse.
