Title: I'm not really parallelisable
Date: 2015-05-20 01:15

I had a lot of fun last weekend:

- I played the [defcon ctf qualification]( https://blog.legitbs.net/2015/05/def-con-ctf-2015-qualifiers-are-complete.html ) with 
(thanks to [crowell]( http://jeffreycrowell.com ) who invited me) the (amazing) [Shellphish]( http://shellphish.com ),
and we got the 12<sup>th</sup> place over 1472 teams!
- I played the [hashrunner]( https://hashrunner.phdays.com/ ) contest with the [john]( http://www.openwall.com/john/ )-user team, and we ranked 2<sup>nd</sup>,
a bit behind the [hashcat]( https://hashcat.net/hashcat/ ) one. Trying to get as much broken hashes per second on a machine like the [HPC village]( http://openwall.info/wiki/HPC/Village )
with little experience about such kind of hardware was a though challenge, especially when [solar designer]( https://twitter.com/solardiz) is making clear that it is *my* responsibility to keep this machine loaded ;) 
I had a lot of fun trying to guess patterns, wordlists, and assembling, *crafting* rules, seeing john spiting results, … you can read the team writeup [here]( http://openwall.com/lists/john-users/2015/05/24/4 ).
- I managed to install and run an [old game]( http://archive.planetvampire.com/Bloodlines/ ) on wine, running inside GDB (I might blog about this.): it was awful.
- I wrote a [blogpost]( http://radare.today/defeating-baby_rop-with-radare2/ ) on the radare blog about how to pwn with radare2.

The point is that I'm not really wired to be highly parallelisable: Saturday was so exhausting that
I was highly unproductive during the whole Sunday. I should have followed the UNIX motto "*Do one thing and do it well*"
instead of the emacs one ;)


Anyway, lesson learned.
