I sometimes find it annoying that IPv6 still isn’t readily available. This raises the following question in my head: what can we, as tech-savvy individuals, do about it, now?
Using Flex and a Bison GLR parser in the Facebook Hackercup
In this post I’ll discuss how Bison’s GLR-parser feature can be used to solve a Facebook Hacker cup parsing problem. The problem at hand requires parsing text that is ambiguous, i.e. there exist multiple correct interpretations.
Back after mod_wsgi & Python 3
The Python-powered bits of this website (my portfolio as well as the redirection to the blog that’s active for ‘/’ unfortunately) threw up HTTP error 500’s since Nov 18. Unfortunately I only now noticed this, though I’m not sure if Django’s email reporting system would’ve alerted me about this. I got the following errors: [usual …
Raspberry Pi + 7 segment display = wireless device counter
This blog post will look at using the GPIO (General Purpose Input/Output) ports of the Raspberry Pi to drive a 7 segment display, which will display the number of wireless devices on a wireless network. I think this is a project where the Raspberry Pi can really shine – it would take more work and …

Moving from Amazon EC2 to a VPS
In my “hello world” blogpost, I mentioned that I used an Amazon EC2 micro instance to host this website (as well as other content, like my personal bugtracker, repositories etc). This was very attractive at the time, since using the Amazon Web Services Free Tier meant that I could do that for free (or well, …

I unfortunately haven’t had the best experiences with ISP-provided routers so far, so when I got the O2 wireless box IV (a rebranded Thomson TG587nv2), I wanted to configure it as a bridge or “modem only”, so that I could let one of my routers (that has an Ethernet WAN port) do the routing. Ideally, …

WPA 2 Enterprise from scratch using a Raspberry Pi
Have you ever seen one of these username/password dialog boxes popping up when connecting to your university or work wireless network? This is commonly known as WPA2 Enterprise. Wouldn’t it be cool to have this at home, too? 🙂 This blogpost will describe the steps required to setup such a system from scratch, using a …

Raspberry Pi – first impressions
My Raspberry Pi finally arrived yesterday! Here are some of my first impressions. I had two SD cards prepared, a blue SanDisk SDHC class 4 with the latest Debian “squeeze” and a Transcend class 10 with Arch Linux (01-03-2012). Both were 16GB, both booted. Debian somehow didn’t allow me to use my keyboard and mouse …
Hello world!
Welcome to my little website. Currently it mainly houses a portfolio with some of the projects I’ve been involved in (it’s not an exhaustive list), and then this blog. In case you’re interested in the technicalities: I chose WordPress because it’s a mature blogging system, but wanted to use Django for my portfolio… So, in …
