  54. Line breaks in

    A really frustrating issue I had when writing my project report, was that of dealing with source code formatting.

    Two reasons you might want to do this. You want to host a Rails application using Mongrel via Apache and mod_proxy_balancer.

  64. Subversion 1.4.0 from source via Apache 2.2 on Ubuntu Dapper

    This howto assumes you’ve already followed my Building Apache 2.2 from source article. Now we’re going to install Subversion 1.

  65. Ubuntu Dapper Web Server How-to

    It’s finally here, my updated how-to on how to get Ubuntu Dapper up and running as a home web server.

    Note: Didn’t have time to really write this article up - maybe some time I will - but I’m posting it here just in case it comes in handy for someone.

  68. Using Tomcat Ant tasks

    I’m now really loving Ant for compiling my Java projects together. It really has solved the problem of figuring out what to update, or going through countless commands to compile each package etc.

    My group project at University now consists of three smaller projects that provide an overall RSS service.

  71. Mac friendly Java apps in a few lines

    If your one of my regular readers (ha!), then you’ll know I’m starting a Group Project for University.

    At University, they’ve blocked ports for all IM applications, including IRC. This sucks, because IRC can actually be really helpful for asking for advice on things such as C++ or C.

  74. Ubuntu 5.10 web server howto

    I reinstalled my home server today (well, I actually started yesterday, but today I finished from scratch again) and wrote down what I did.

  75. Java foreach loop

    Coming from a PHP background, it’s always annoyed me that I can’t use something as simple as a foreach() loop in my C++/Java applications.

  76. Setting up XDMCP for Mac

    I just finished setting up a spare PC I had with Ubuntu on it. Thing is, it’s damn noisy so I want it stuffed up in the loft out of the way.

  77. Sorting a Vector using Collections.sort()

    Collections.sort() allows you to sort a Collections framework that is inherited from the List class. The Vector class is, so that’s great!
