Audio quality
This is just one of those topics which comes up from time to time in my life (probably because I consume a lot of media). I was recently watching the Jim Zemlin interviewed by Jeremy Allison (Jim Zemlin is the Executive Director of the Linux Foundation) on the Google Open Source YouTube channel and was…

mytrendyphone.co.uk review
My assignment – which I choose to accept 🙂 – was to review a mobile accessories site, namely mytrendyphone.co.uk. All the signs for this site check out: It was registered a couple of years ago and didn’t move around much It has several real seals (real meaning that they are linked to the originating site,…

Setting up IMAP with Yahoo! Mail
I’m a long time Yahoo Mail user. Just to illustrate how long I’ve been with them: when I joined the space available was a couple of MBs! I staid with them because I was mostly satisfied (never really caught the GMail bug), however recently I started looking for options to consolidate the different email accounts…

Manually enabling IP routing in Windows XP
While Internet Connection Sharing is a nifty tool, there are some cases where you would like to do the steps manually. One such case would be if the “primary” network is already using the 192.168.0.1/24 address space, since ICS is hardcoded (as far as I can tell) to use the same network. One concrete case…

Is hand-writing assembly still necessary these days?

Performance was always something I’m interested in, so I repeated and extended the experiment. Here are the numbers I got. This is on a Core 2 Duo T5500…

Why you should use 0.0.0.0 in your hosts file – redux
Some time ago I (wow, time files!) I suggested that using 0.0.0.0 for host-file based blocklists would be faster than using 127.0.0.1. Above you can see an other reason for using 0.0.0.0: some applications take up port 80 on the localhost and accessing it can (potentially) create havoc. In the example above TeamViewer (which is…

Augmenting Log4J stack traces with class versions
If you have multiple versions of your code in production, it is extremely useful for the log to include the version of the classes when producing a stacktrace, otherwise it is very hard to match the lines in the stacktrace with the lines of the source code (sidenote: there is an optimization in the Sun…

Remote debugging with Java
Sometimes you have the situation that an issue is only occurring on certain machines or only at a certain time of day. There are a couple of possible methods to investigate such an issue (like: adding extra logging), however I would like to add an other one: remote debugging trough TCP/IP. To do this, start…
