I was fortunate enough to visit the Trenton Computer Festival last weekend. The show struck a very interesting mix of new and old, commercial and educational. Attendees were writing programs in BASIC on an Apple I (courtesy of the Vintage Computer Federation) not more than five feet from where students were demonstrating their FIRST robot.
The one-day event featured over fifty demonstrations, talks, and workshops on topics ranging from a crash course in lock picking to the latest advancements in quantum computing. In the vendor room you could buy a refurbished laptop while just down the hall talks were being given on heady topics such as using neural networks and genetic algorithms for day trading on the stock market.
Recent years have seen a widening of the content presented, but TCF’s longevity means there is a distinct “vintage” vibe to the show and the culture surrounding it. Many of the attendees, and even some of the presenters, can proudly say they’ve been attending since the very first show in 1976.
There was simply too much going on to see everything. At any given time, there were eleven talks happening simultaneously, and that doesn’t include the demonstrations and workshops which ran all day. I documented as many highlights from this year’s TCF as I could for those who haven’t had a chance to visit what might be the most low-key, and certainly oldest, celebration of computing technology on the planet. Join me after the break for the whirlwind tour.

Where’s Cardboard Snowden?
On the last day of DEF CON, I talked to some charity hackers, checked out the lockpicking village, and learned how insecure my router is in the wireless village.

What Maker Faire would be complete without teaching children the joys of jiggling and twisting locks until they’ve opened? Toool, the open organisation of lockpickers made their way to New York this weekend to show off their bumping skills and get the kids interested in manipulating small mechanical devices.
The guys from Toool had a very cool setup – just a bunch of tables and chairs with a few picks and torsion wrenches. There were a few classic Master Locks on the table, but also a series of six tumbler locks each labeled with a number 1 through 6 signifying how many pins were in the lock. The idea is to get someone started on a one-pin lock, and eventually have them work their way up to the full six pins.
In the video after the break, one of the more animated guys from Toool explains why they were there, and also shows off picking a Master Lock twice in under 30 seconds. Seriously, people: educate yourself on locks before buying one.

[Steffen Wernéry] has published a video of the impressioning contest at LockCon. We learned about key impressioning at this year’s HOPE conference. You start the process by inserting a key blank into the lock. By turning the lock until it stops and then moving the key up and down you create marks on the blank’s face. Take a file to those marks to remove the extra material and then repeat the process. Once the pins are set properly, they’ll stop leaving marks on the blank. It takes a lot of skill to do this right, but you end up with a perfectly functional key. [Barry Wels] managed to win the competition in 5:30 with second place coming in at 6 minutes.
The Open Organisation Of Lockpickers (TOOOL) is planning a new annual gathering for lockpickers. October 9-12th they will hold the first ever LockCon in Sneek, Netherlands. The event was spawned from the Dutch Open lockpicking championships, but they’ve decided to expand beyond just competition into a full conference. This year the conference is limited to just 100 lockpickers, technicians, manufacturers, hackers, and law enforcement members. They’ll compete in picking competitions, safe manipulation, and key impressioning.
On a related note: Organizer [Barry Wels] just became the first non-German to win an SSDeV competition with his key impressioning skills. We covered key impressioning when we saw his talk about high security keys at The Last Hope. He says it’s only been about two years worth of study and 500 keys to become a master. He managed to open the lock in 5:13 filing two whole keys during that time.

Despite, Hack a Day seeming to be fairly lock heavy lately, we’ve yet to cover a major story from The Last HOPE. At the conference, [Jon King] talked about vulnerabilities in Medeco locks and presented his Medecoder tool. Medeco is really what makes this story interesting; unlike the EU, the US has very few high security lock manufacturers. You pretty much have to use Medeco and it’s found in many government agencies.
The Medeco locks have a vertical row of six pins arranged like most pin tumbler locks. Unlike your average lock, the rotation of the pins is important. When the key is placed in the lock, it not only moves the pins to the correct height, it also rotates them to the correct orientation. A sidebar blocks the cylinder unless the pins are rotated properly. Each pin has three possible orientations. They’re biaxial as well, which means the pin’s offset point allows for three more possible positions.
