35C3: Biggest Communication Congress, Yet Little Chaos

January 10, 2019 by Elliot Williams 4 Comments

Every year for the past 35 years, the German Chaos Computer Club has met just after Christmas for a few days of “Spaß am Gerät” — having fun with the machines. And that’s everything from trying to bring an old PDP-8 back into running condition to forging new software to replace the old and busted social media platforms that permeate our lives. The sum total of around 17,000 people doing the nerdy stuff that they love, and sharing it together, is both amazing and inspiring. Four days of little sleep and much socializing later, I bet there was still another four days’ worth of stuff to see.

The official theme this year was “Refreshing Memories” which honestly sounds a bit too much like a cola slogan, but was a great opportunity to think back on the hacks of the past that got us where we are. Assemblies put up shrines to their hacker heroes of the past. Retro computers were everywhere, in the talks and on the floor. This year’s Congress was a great time to look back and remember, but also to create new memories for the future. On that front, it was a total success.

But the unofficial theme this year was “Smooth Running”. Everything went very well, which is no small feat considering that the infrastructure, decoration, security, and even the medical response teams are from the Chaos community. It’s the depth of engagement that makes this work: of the 17,000 people who showed up, just over 4,000 of them volunteered for “angel” shifts — meaning they helped guard the doors, staff the info desks, or build up or tear down. It was the largest ever CCC, and you could feel it, but they pulled it off, and then some.

The angels are geeks just like you and me, and since everything went so smoothly, they had time to play. For instance, the phone operations people offer DECT phone service so that attendees can bring in their home phones and use them at Congress. In years past, the lines to register and enroll phones were painfully long. This year, it all happened online, and the result is that the phone ops crew got bored. That explains how they had time to establish roaming home-phone wireless service in some of the normal Leipzig city trams. Wait, what?

Hackaday Assembling At 35C3

November 26, 2018 by Elliot Williams 5 Comments

Hackaday is going to be at the 35th annual Chaos Communication Congress (35C3), December 27th – 31st, and we’re putting together an assembly. If you’re coming to 35C3, come join us!

If you’ve never been to a Congress before, it’s an amazing scene. This year over 15,000 hackers will take over the Leipzig Congress Hall, bringing whatever they’re working on with them, and showing off their last-minute dazzlers. Congress is awesome in both senses of the word: simultaneously incredible and a little bit intimidating.

With the scale of the Congress approaching absurd proportions, it’s nice to have a home base. “Assemblies”, small-ish gatherings of friends, members of a hackerspace, or even just like-minded folks, join forces and get some table space and Ethernet connections to call their own, and this year we’ll be flying the Jolly Wrencher.

November 28th is the deadline for changing our headcount, so if you’d like to take part, click over to the Hackaday 35C3 Assembly IO project ASAP and leave a comment or join the team so we have a good estimate. If you’ve already got a home away from home, we’ll keep some extra seats warm for you to come by and chat. [Elliot] will also be wearing his press hat, so if you’ve got a project in desperate need of a Hackaday writeup you’ll know where to find him.

Hackaday, assemble!

Great People And Culture At 34th Chaos Communication Congress

January 2, 2018 by Elliot Williams 18 Comments

If you’ve been to a Chaos Communication Congress, you know the feeling — the strange realization after it’s all over that you’re back in the “real world”. It’s somehow alienating and unfriendly in comparison to being surrounded by computer freaks, artists, hackers, activists, coders, and other like-minded individuals over the four days of the Congress. A hand-written poster by the podcasting center read “Endlich, normale Leute” — “At last, normal people” — which is irony piled on irony but the sentiment is still right for certain strange values of “normal”. Normal hackers? You’d probably fit right in.

We cover a lot of the talks from the Congress, because they’re first-class and because you can play along at home, but the real soul of the Congress is people getting together, making something temporary and crazy, talking over their common plans, learning new things directly from one-another, and simply having fun. Here’s our chance to give you a little of the other side of the Congress.

34C3: Ultimate Apollo Guidance Computer Talk

December 28, 2017 by Tom Nardi 14 Comments

While it might not be as exciting as the Saturn V rocket itself, the Apollo Guidance Computer (AGC) was one of the most important developments of the entire Apollo program. While comically underwhelming compared to modern hardware, the AGC was nothing short of revolutionary when it was developed in the 1960’s. Before the AGC, the smallest computers were about the size of a refrigerator and consumed hundreds of watts; both big problems if you’re trying to pack them into a relatively tiny space capsule with limited resources. Not only did the AGC get humanity to the Moon and back, but it also redefined the state of the art for microcomputers, paving the way for the desktop systems of the 1970’s.

That said, the design and operation of the AGC is downright bizarre to modern eyes; it comes from a time of limitations we can hardly fathom. With this in mind, [Michael Steil] and [Christian Hessmann] put together “The Ultimate Apollo Guidance Computer Talk” for 34C3.

This hour-long presentation walks viewers through every aspect of not only the AGC itself, but how it interacted with the Saturn V rocket and the overall lunar mission. Even if you aren’t enough of a vintage computing aficionado to appreciate the complexities of core rope memory, the presentation gives a fascinating look at the gritty details of one of humanity’s greatest achievements.

Though very slick and easy to understand graphics, [Michael] and [Christian] break down the alien world of the AGC. Even if a lot of this part of the presentation goes over your head, just listen for the sounds of laughter or applause from the audience: that’s when you’re looking at something really off-the-wall.

Of particular note during this presentation is the explanation of how the astronauts actually interacted with the AGC. The AGC’s display and keyboard (referred to as DSKY) may seem rather obtuse even to those who used to hack on a VT100, but [Michael] and [Christian] explain how it’s not quite as complex as it seems. Comparing the input and output of the DSKY with what we would see on a more contemporary command line interface, the presentation makes the case that it’s actually a very straightforward way of talking to the computer.

There’s also a complete breakdown of the different phases of the Apollo mission from launch to landing, explaining what the AGC would be doing at any given time. The DSKY is overlaid on actual footage from the Apollo missions, giving a unique perspective as to what the astronauts would see on their computer during iconic moments such as stage separation or lunar touchdown.

If this presentation has you hungry for more Apollo-era computer technology, we’ve covered plenty of projects to keep you occupied. From building a replica DSKY to leisurely paging through the printed version of the AGC’s source code.

34C3: The First Day Is A Doozy

It’s 5 pm, the sun is slowly setting on the Leipzig conference center, and although we’re only halfway through the first day, there’s a ton that you should see. We’ll report some more on the culture of the con later — for now here’s just the hacks. Continue reading “34C3: The First Day Is A Doozy” →

Hackaday At 34C3

December 24, 2017 by Elliot Williams 19 Comments

It’s that time of year. While the rest of the Christmas-celebrating world sits around and plays with the toys that they got out from under the tree, German nerds head off to the biggest European hacker con: the 34th annual Chaos Communications Congress, running Dec. 27th through 30th.

The CCC is both a grandparent among hacker cons, and the most focused on using technology to improve the world and bringing folks together. (The “communications” in the name is a dead giveaway.) This year’s motto, “tuwat!” is slangy-dialecty for “do something!” and is call to get up off the couch and use your super-powers for good.

If you can’t get over to Leipzig to join us, you’ll be able to read our extensive coverage starting up shortly after the opening ceremonies, and probably stretching well into 2018. And since the CCC media folks manage to stream every talk, hackers all over the world can follow along live. Most talks are in English, so get together with folks in your hackspace and have a video night!

And if you are in Leipzig, be on the lookout for [Elliot] who will be wandering around, attending workshops, and writing down as much as possible. Show me something cool, rave about a particularly good talk, or just say “hi”.

33C3: Works For Me

December 30, 2016 by Elliot Williams 20 Comments

The Chaos Communication Congress (CCC) is the largest German hacker convention by a wide margin, and it’s now in its thirty-third year, hence 33C3. The Congress is a techno-utopian-anarchist-rave with a social conscience and a strong underpinning of straight-up hacking. In short, there’s something for everyone, and that’s partly because a CCC is like a hacker Rorschach test: everyone brings what they want to the CCC, figuratively and literally. Somehow the contributions of 12,000 people all hang together, more or less. The first “C” does stand for chaos, after all.

What brings these disparate types to Hamburg are the intersections in the Venn diagrams. Social activists who may actually be subject to state surveillance are just as interested in secure messaging as the paranoid security geek or the hardcore crypto nerd who’s just in it for the algorithms. Technology, and how we use it to communicate and organize society, is a pretty broad topic. Blinking lights also seem to be in the intersection. But on top of that, we are all geeks. There’s a lot of skill, smarts, and know-how here, and geeks like sharing, teaching, and showing off their crazy creations.
