A bountiful year for open source

The feasting on open source software continues but some wonder if the check might be coming due

It is now just over 12 years since seven people sat down in a conference room in Silicon Valley to fix what they saw as the marketing problem with the words "free software." Most people thought that the word "free" meant only that no one had to pay. It seemed they didn't have an attention span long enough to try to grok what Richard Stallman was saying when he kept repeating, "'free,' as in speech."

After considering dozens of combinations, Christine Peterson hit upon "open source," and the phrase has grown to represent a section of the software marketplace big enough to merit its own end-of-the-year roundup.

If anything, rounding up the news about open source is impossible these days because there's just so much of it. Still, gross generalizations are easy to make as long as everyone realizes they're wrong as often as they're right. There are hundreds of thousands of projects floating about the Web, and any statement is probably correct for some subset, however small.

There's little doubt that open source projects are flourishing, at leasta as measured by their sheer numbers. There are 1.49 million projects at GitHub. SourceForge tallies more than 2 million downloads a day.

Code is everywhere, and it is more and more likely to be open source from the bottom to the top of the stack. Ruby, Python, Perl, JavaScript, and PHP dominate the list of top languages at GitHub. This code, in turn, runs on open source libraries that sit on Linux. Although proprietary coding tools and extensions continue to proliferate, the core is increasingly fully open source.

This domination is pushing into other areas. Open source content management systems like web.py, phpBB, CakePHP, Lift, Drupal, Joomla, and probably hundreds of other open source CMS frameworks are packaging up most of the information you read today. It is rare to find a website that depends on just Apache to deliver the content.

Scientists and academics are pushing open source software even further. Mathematicians are exploring bundling their equations in Sage notebooks, and biologists seem to love Python. Moodle is the dominant courseware tool. The list from the world of research is endless, especially since it's now common for colleagues to expect open source code and data to accompany the text.

There's even more good news on the business side. Champagne corks were popping as open source advocates everywhere celebrated the predictions that Red Hat -- one of the original believers in openness -- should clear $1 billion in revenue for the year if IT departments keep spending at the current rate. This milestone is all the more noteworthy because MySQL was earning much less when Sun paid $1 billion for it. At current stock prices, Red Hat is worth more than $9 billion.
