Goldman Sachs security incident
Allegedly the source code for Goldman Sachs “low latency (microseconds) event-driven market data processing, strategy, and order submissions” systems have been stolen by an insider (via Zero Hedge here and here). Personally I find this (and similar cases) overblown for several reasons: Sourcecode by itself is worthless. The important thing is the mathematical model behind…

Panda Challenge
I know that it is kind of short notice, but I too have only found about it recently: the Panda Challenge (from Panda Security). It begins tomorrow (on the 7th of July) at 10 AM GMT+1 and consists of three rounds. Picture taken from Joachim’s photostream with permission.

More benchmarking in the 127.0.0.1 vs 0.0.0.0 issue
I’ve done a little more benchmarking in the 127.0.0.1 vs. 0.0.0.0 issue: <script>var start=new Date();</script> <script src="http://ad.a8.net/foo.js"></script> <script src="http://asy.a8ww.net/foo.js"></script> <script src="http://a9rhiwa.cn/foo.js"></script> <script src="http://www.a9rhiwa.cn/foo.js"></script> <script src="http://acezip.net/foo.js"></script> <script>var stop=new Date(); alert(stop.getTime() – start.getTime());</script> What this code does, is to try to include javascript files from five sites and measure the time it takes to process these tags.…

Posting links from delicious to Blogger
I collect quite a long list of links while I “surf the web”. Until now I’ve done the Mixed Links series, but I’ve been looking for ways to automate it. Enter delicious (or del.icio.us as it was formerly known): it has a nice Firefox plugin and theoretically it can post your bookmarks automatically to your…

URIBL.COM – Realtime URI Blacklist Posted: 03 Jul 2009 10:17 PM PDT URIBL provides different RSS feeds (based on registrar, nameserver, etc). Cool! fb-contrib™: A FindBugs™ auxiliary detector plugin Posted: 03 Jul 2009 06:57 AM PDT Alternative FindBugs detectors.

Speedy hosts blocklists
One of the ways to block your machine from connecting to “unwanted” hosts (however you define this criteria) is to list the DNS name of the host in the hosts file of your system and associate it with a different IP address than the real one. While this solution has some limitations (for example: it…

Profile first!
I was using my code to parse a medium-sized CVS log and it was being slow (~1min). So, like an idiot I said: I know that the algorithm is quite slow, so I optimize it. Here is a version which is twice as fast as the original version: use strict; use warnings; use Test::More tests…
