For a computer, software content is king. Programmable computers began the home computer revolution over 20 years ago. The modern revolution is Open Source software, giving immeasurable utility with no cost or risk. Sadly a lot goes under the radar but here are five sleeper apps really worth checking out.

We found open source apps that could help you get started in a new hobby, read more, improve your mind, and become more spiritual. And for the (admittedly small) group of people whose New Year's resolution is to try open source for the first time, we assembled a small group of apps for open-source neophytes.

A quick look at KDE-Apps.org reveals that new apps are added daily. I periodically browse through the latest KDE apps to see if anything stands out, and I found these five, some of which are in early development.

Security company Qualys has released a new open source tool, 'BlindElephant', which can accurately fingerprint web applications down to version level in order to better manage the security issues which now plague such software. According to the company, the need for such a tool is pressing.

Comic books, DVDs, old vinyl albums, Star Wars figurines -- collecting things is fun. What's not fun, though, is keeping track of it all. Here are five open source collection management apps to help you organize your stuff.

When it comes to cooking apps, Mac OS X has SousChef and Windows has MasterCook. Not only can open source developers whip together good applications, it turns out some of them are also whizzes in the kitchen. Let's take a look.

Ever so often, I take a stroll over to KDE-Apps.org and look at some of the fantastic creations people from the KDE community develop. There are a wide range of apps in nearly every category, but I have selected 5 that stand out and would be very useful additions to my desktop and hopefully yours too. All of these apps are either new or have been recently updated within the past few months.

Among the open source apps we'll see this year are browsers and operating systems, mobile platforms, productivity applications, and IT admin tools -- and a few hard-to-classify items. Many will give you the wriggly "Oooh, cool!" sense of discovery.
