Black Duck Software, a company best known for its services and software for the procurement and re-use of open source software, has acquired Koders, and with it the popular Koders.com search engine for free and open source software code (FOSS).

Bradley Kuhn, the technology director of the Software Freedom Law Center (SFLC) expressed dismay this week after learning that Black Duck Software was granted a patent that covers software methods for detecting and resolving open source software licensing conflicts.

What's the most popular open source license currently in use? If you said GPL you would be right. But how did you know?

What is the most popular programming language used by open source developers? The answer depends on how you define popularity. According to a new study from Black Duck, a software-license code analysis vendor, C represents more than 40 percent of all code written for open source software. Black Duck made its determination by counting the actual lines of code.

Black Duck Software, the leading global provider of products and services for accelerating software development through the managed use of open source software, marked the first anniversary of the release of version three of the open source GNU General Public License (GPLv3) with a study of trends in its use.

BLACK Duck Software, a proprietary software company which was founded by a (former) Microsoft employee, has just entered an agreement with Microsoft.

More proof time flies. GPL v. 3 is one year old. To “celebrate,” Black Duck Software looked at some of its own license resources , including its list of V.3 licensees, concluding that the divide between V.2 and V.3 licenses still lives, one year on. Black Duck founder Douglas Levin said inertia is on V.2’s side.

The last time we wrote about Microsoft insiders, we also mentioned Black Duck as a possibility. Some insiders don’t perceive themselves as such, yet they naturally function in this way.Here you have a Microsoft employee founding and heading a company that sells services around Free software FUD. The company has developed proprietary software only.

Since acquiring the Koders.com code search engine earlier this year, Black Duck Software has added more than 200 million lines of code to the Koders.com search repository. Black Duck says that an analysis of search requests reveals, "Ruby is now the fourth most requested language on Koders.com, after Java, C/C++ and C#." That's interesting information, to be sure, but what does it mean?
