The Thirty Second Chaos Communication Congress

I still can't describe CCC, you have to go.

I wrote a post about how to survive congress, but didn't publish it. It contained a list a little like this:

  • All of the talks are recorded, streamed and put online at media.ccc.de.
  • The self organised sessions are not recorded.
  • The most interesting things are happening at the assemblies.

These points hold true, my original suggestion because the talks are available after the fact there isn't much point sitting in the lectures. At 32c3 I didn't attend any of the talks, this was a mistake. I really regret not going to any talks.

Going to the talks gives you something to talk about with the people at CCC.

The self organised sessions I went to were great and hanging out with people at their assemblies and at the Scottish Consulate was great. If I had been in a lecture instead of at our table I definitely would have missed #toiletparty . But I think if I had gone to some of the talks early each day I would have gotten much more out of the event.

Next CCC I will head to the event with more of a plan. I don't think there is a right way to do congress, it is just too insane, but I will try to go to each one in a different way.

DSO138 Kit

Around the December holidays I received three sets of the jyetech lcd scope kit. This cheap kit (~£10) builds a small low frequency (1Msps) oscilloscope.

In all it took me about 2 hours to solder everything together, that includes me misplacing a resistor and a capacitor. I wish I had sorted the resistors with a multimeter that scales automatically before starting.

I am planning to build these kits into some audio projects later in the year, getting three of them was great luck. The kit was really straightforward to build and didn't take too long, there are serial logging features on the board as well. This kit could be built into a portable work bench without much thought.

Happy Hackmas from 57North

We have two old Black and White CRT monitors in the hackerspace, they look really cool. I put together a Card and gif for the holidays:

I used a raspberry pi running FreeBSD for each monitor. The bottom monitor is running aafire which gives a nice fireplace effect. I did some big text in figlet for the message.

I also put together a paper card by using the gcard package in latex to put together some cards. This relies on double sided printing to get the message inside the cards. It was a bit of trouble(I had to trim the cards down), but the cards came out quite well for an hours work.

This generates two pdf files, I used pdfjoin to join them together into one file:

Quick gifs

In the last post I showed an animated gif of the of the post source run through sent.

This gif was super easy to make manually, I ran sent on the post source file, then I ran my screenshot tool from dmenu on each slide. I stepped through each slide manually.

For a long presentation, or if I might do this more often I would probably automate this in some way.

I was left with a directory of files call 1.png, 2.png, for each of the slides. I used the convert tool from imagemagick to turn these into an animated gif.

$ convert -delay 100 -loop 0 *.png sent.gif

Animated gifs can be played with the animated tool from imagemagick to see how the delay is working.
