Linus Torvalds Switched Back To Gnome

Linus Torvalds, Linux's creator, dislikes the GNOME desktop. There was a big flame war(s) between Linus Torvalds and the GNOME community. At one point he claimed that - "Gnome seems to be developed by interface Nazis and that its developers believe their users are idiots". And guess what? Who made the switch to Gnome?

Free Software Usability Issues and Solutions

Matthew has published a nice easy titled as "Why Free Software has poor usability, and how to improve it":

Many of these problems are not specific to Free Software in particular, but to volunteer software. Hobbyist proprietary programs often have poor designs for many of the same reasons. But the easiest way of getting volunteers to contribute to a program is to make it open source. And while thousands of people are now employed in developing Free Software, most of its developers are volunteers. So it’s in Free Software that we see volunteer software’s usability problems most often.

Misunderstandings of the GPL Licensing is a common issue. It can create problem for both developers and sys admins. Most developers and admin think that they understood all legal mumbo jumbo associated with GPL. You can take the Free Software licensing quiz and test your knowledge of the GPL and LGPL.

Nice idea.

Michael Ogawa has created some stunning visualizations for open source software projects such as Apache, Python, Eclipse IDE, and Postgres. From the project home page:

This visualization, called code_swarm, shows the history of commits in a software project. A commit happens when a developer makes changes to the code or documents and transfers them into the central project repository. Both developers and files are represented as moving elements. When a developer commits a file, it lights up and flies towards that developer. Files are colored according to their purpose, such as whether they are source code or a document. If files or developers have not been active for a while, they will fade away. A histogram at the bottom keeps a reminder of what has come before.

Programmers deliberately avoiding association with Vista, and habitually keeping away from Vista for Mac OS and Linux. According to a survey issued last week by Evans Data Corp. The headline was that most developers are still not targeting Windows Vista when they write new apps. Only 8% of the 380 developers surveyed were writing for Vista; 49% were still targeting Windows XP.

It appers that programmers may be developing an interest in something beyond the size of the installed operating system base, which is good news for Linux.
