Addicted to Open Source
I have been using GNU/Linux and open source software for the past few years. It started as a way to give life to old PCs that I retired for more powerful machines to run Windows. Those GNU/Linux machines were mostly experimental acting as file servers and web servers. It wasn't until this past year I went to the other side and started using GNU/Linux as my preferred OS.
The last server I built, I designed to run Ubuntu Linux instead of Windows. Now I run Windows on my older machines. There are still plenty of applications I use my Windows machines for and they work well, but when I look for a application to fill new need I look to run it on my Ubuntu machine. More specifically, I look for web 2.0 applications using LAMP (Linux/Apache/MySQL/PHP). This allows me to use the applications from any browser on any machine.
My current web applications running on on this server are:
The most recent addition was dotProject. It meets all my needs for project management that Microsoft Project offers yet is free and always available online (as long as my server is up). As a web enabled application there are other features not available in MS Project such as easy collaboration by multiple users via the web and automatic emails of tasks assigned and reminders when they are due.
