The Architecture Centrum Amsterdam (ARCAM) (a.k.a Architectuurcentrum Amsterdam) is an odd looking building. Originally built in 1997 to be part of the nearby NEMO science centre, in 2003 it had a “blob” wrapped around it.
The first update of eMusic/J in about 4 years has been released. Nothing exciting about it, it just fixes some compatibility issues with newer Java things on Windows and Linux. Download it here.
I have just acquired a YubiKey (the standard one) and wanted to use it to provide 2-factor authentication for SSH. In case I lose the key, I also want a fallback option so I don’t lose access to the server. The documentation for this seems a bit scattered, so here’s my reference for how I… Read More: YubiKey logins with SSH »
Today I had cause to want to track the per-user (per-MAC address, really) traffic counts on an OpenWRT-based router. There’s nothing I could see that was built in, so I dug around and found wrtbwmon, which is a pretty good script for this sort of thing. However, it doesn’t work with the OpenWRT version I’m… Read More: Per-user traffic monitoring on OpenWRT »
I meant to post this here a while back, but kinda forgot to. Anyway, on Monday last week I finally submitted my thesis. The title is “The Impact of Representation on the Evolution of Genetic Algorithms.” Now I just need to sit back and wait until the examiners get it, mark it, and probably send… Read More: Thesis Submitted! »
I’ve been setting up a Puppet system at work so we can easily set up virtual servers, and also so that all the configuration is in one place. Yesterday, someone suggested to me how I can have our existing Nagios system monitor the state of the puppet configuration. This allows me to be notified if… Read More: Monitoring Puppet with Nagios »
The opportunity has come up for me to escape Dunedin, and go a long way away for an indefinite time. So, I’m jumping on the idea, and planning on moving to the Netherlands, Deventer specifically, to work for Topicus. I’ll have a 6-month contract with them to start with, that is evaluated after 3 months… Read More: Returning to Europe (hopefully) »
I realised that I’d forgotten to mention this here, so now I’ll amend that.In July/August, I’ll be spending five weeks in Europe. I leave NZ on the 13th of July, and get back on the 22nd of August.It’s just for a holiday, so should be a fairly cruisy time. And I miss out on some… Read More: Going to Europe »
First update in a while, just fixes to various things. Overhauled the filename cleaning stuff, hopefully finally fixing issues on windows. — found more filenames that windows dies on, so this deals with them. Hopefully that’s the last of them. If the option ‘spacesToUnderscore’ is ‘true’ then spaces will be converted to underscores in filenames.… Read More: eMusic/J 0.25 released »
Here’s something a bit more computer-sciencey than usual. For something at work, I have had to implement a function parser, so you can type ‘1+2*b‘ and it’ll work it all out, with correct operator precedence and so forth. To do this, I use a three-step process: Tokenise the input, and at the same time convert… Read More: Extension to the ‘Shunting Yard’ algorithm to allow variable numbers… »
