Hey, kudos!
You don't run arbitrary scripts either!

My apologies for the JS on this page…
it's prettify.js for syntax highlighting
in code blocks. I've added one line of
CSS for you; the rest of this site
should work fine.

  1. 28c3 & Kontakt Informationen

    I’m going to be traveling abroad for about six weeks, so anyone who is trying to contact me during this period should know that it may take a while to get back to you. I’m going to the Chaos Computer Club’s 28c3, so I’ll post updates on things that I learn there. I also believe that I will be giving a short talk on the artificial intelligence work I’ve been involved in.

    I’ll be getting a German SIM card when I get off the plane in Berlin, and I’ll probably not post the new number here, or maybe I will. Normally I’m worried about people tracking me down, but hey, why not — it’s a throwaway SIM afterall. It’s not like anyone’s going to stalk me all across Europe.

    After Germany, I’ll be in Austria, Denmark, Czech, Sweden(?), The Netherlands, and maybe a few other countries. I want to mention that the only reason someone as poor as I is able to go all these places is due to a couple of amazing hackers at Noisebridge in San Francisco, who felt like I should be able to go, provided tons of support, help, and encouragement. Their only request for me was that one day I pay it forward.

  2. Progress & Problems: Tmux for Android

    One of the things I need for xqdr, the flying robot that I’m building, is a terminal multiplexer, like screen or tmux. I use tmux, personally, and jeepers wouldn’t it be neat to have it run natively on my phone so that I don’t have to use ConnectBot to an outside server and then do “tmux attach”?

    Fortunately (or so I thought when starting this project), tmux is written entirely in C. This turned out to be difficult, and so I’ll outline how I did it.

    The Android kernel uses a slimmed down version of standard C libraries (libc.so), called bionic. This is where all the allowed calls are stored. It’s possible to either:

    Surprisingly, I attempted the second option first. This was insane. I had to compile a compiler to compile a compiler to compile a compiler to compile a shared object library through a perl wrapper to compile the code. I think I made it through all the compiling compilers parts, and then my finished compiler crapped all over its pants.

    It was at this point that I decided to check my phone, and I realised that CyanogenMod7 already has a shared object library for standard C. (It’s at /system/lib/libc.so). There is the possibility that I could use this pre-ARM-compiled library, bundle it with tmux, and then use Android NDK to compile tmux for ARM. This would also necessitate creating a .JNI makefile for the frontend, which includes a trivial amount of Java to wrap the native code.

    I’ll update when I finish or fuck myself over, but right now I’m getting on brutal series of international flights for Chaos Computer Club‘s 28C3 in Berlin, and my connection is slower than liberal reformist tactics are at creating a freer society.
