While we all have our own reasons for liking Linux and open source, here are my top five (and a half!) reasons why, as a power user, I prefer to use Linux. You’ll notice that these reasons are quite a bit different from why I think Ubuntu makes a great operating system for Mom, which just goes to show how versatile Linux can be.

Ubuntu community leader and Server and Cloud Ubuntu Developer, Dave Walker, explains the processes behind bringing Maverick Meerkat to the masses…

A hybrid engine that runs on gas and electricity. A football star who plays both defense and offense. A politician who understands social justice and capitalistic expansion.

Let’s say you are doing research on your desktop browser and you need to leave your computer to run some errand. Wouldn’t it be great if you can sync what you are reading to your mobile phone so that you can continue your research on the move? If you are using an Android phone (running Froyo) and Google Chrome/Firefox, you just got yourself a great deal.

The GNU Compiler Collection (GCC) project occupies a unique niche in the free software community. As Richard Stallman is fond of reminding us, much of what we run on our systems comes from the GNU project; much of that code, in turn, is owned by the Free Software Foundation. But most of the GNU code is relatively static; your editor wisely allowed himself to be talked out of the notion of adding an LWN weekly page dedicated to the ongoing development of GNU cat. GCC, though, is FSF-owned, is crucial infrastructure, and is under heavy ongoing development. As a result, it will show pressures that are only seen in a few places. This article will look at a couple of recent episodes, related to licensing and online identity, from the GCC community.

Twitter does not generally allow you to have a discussion. At least not me, who can barely say anything in less than a 1000 words, but here is a recent thread. The opinion about the software not being feature rich is a valid issue and being too complicated is something that I too find with writing software in general. But that the author feels it is less feature rich because it is Open Source, or more correctly, because it is free is something that bothers me.

If you are creating a custom Dialog for Android, and following the Android Developers’ Creating Dialogs tutorial, then most likely you would have faced a Force Close with an exception showing up in logcat.
