I've got it setup and working such that I can send email to gmail, Yahoo! and my work address. However, my work email gets caught up in our spam filter. I'm new to setting up mail servers so...
Hi, I wrote a small app and I am using pynotify to show some messages to the user. It all works fine here in arch, but when I tested it in Ubuntu, the behaviour was very weird. Because of the way Ubuntu shows notifications (as what seems to be a rip of of growl), I can't click on them, or interact with them in any way, for that matter....
Hello I've recently discovered an interesting thing. I've made my own Speedmeter using Flash CS4 and ActionScript 3.0. The Download side is based on downloading 2 Mp3 noise files. Using the built-in method getBytesLoaded() and a simple math it's easy to calculate actual connection speed. Actual speed is evaluated every second. It works...

I have a basic web server that I generated from the mochiweb framework. To start it I use the start.sh script that the framework automatically generates. Everything works fine and the server starts up. Now I have one more mochiweb server that I want to start along with the first one. Again, this starts up perfectly standalone with its st...
For research purposes, I copied a SVN repo to my Windows machine using svnsync so I can replay on my machine without loading the actual server. I've been using PySVN in scripts to control the revision number I want the repo to be in and have been using it fine so far. Now I got a repo from a different project and svnsync got it fine. Wh...

If you are unfamiliar, the command git branch returns something like * develop master , where the asterisk marks the currently checked out branch.
