Manny Lehman dies
| January 14, 2011 | Posted by Karl Beecher under News |
Sad news. Professor Manny Lehman passed away a few weeks ago. Someone I would very much like to have met, he was the originator of the laws of software evolution, a subject which served as a foundation stone of my own PhD thesis, thus making me particularly indebted to his contributions. read more
An Open Source Eco-System?
| September 6, 2010 | Posted by Karl Beecher under Research |
To summarise the prior writings from my doctoral thesis: I’ve shown how there are both notable differences and similarities between certain measures of FLOSS repositories (such as number of contributors attracted, rate of contributions, complexity control work, etc.) The pattern of similarities and differences that emerged clearly differentiated one group (containing Debian, GNOME, and KDE)… read more
The Catalyst Effect in FLOSS Repositories
| April 26, 2010 | Posted by Karl Beecher under Research |
In the course of my PhD studies, I proposed that when a project makes a transition from one repository to another, you could expect to see significant changes to a project’s evolutionary characteristics. Indeed, I covered this in earlier posts, discussing the transition from SourceForge to Debian. Here, we saw that the number of developers… read more
Continuing the Empirical Results: Anti-Regressive Work
| April 19, 2010 | Posted by Karl Beecher under Research |
It has been a while since I wrote about my research into FLOSS, for which there are a few reasons. When last I wrote I was approaching my PhD defence, and for the whole PhD process to come to an end I had to wait until January this year, when my thesis was officially approved.… read more
The Six-Way Epic: Digging Further into FLOSS Repositories
| September 1, 2009 | Posted by Karl Beecher under Research |
Not too long ago, I announced the publishing of my first journal article co-authored with Andrea Capiluppi and Cornelia Boldyreff. My mother was very proud — even if she did not understand a single word of it. I will give a brief summary of the article in this post, and if I succeed in whetting… read more
Journal Publication Confirmed
| March 25, 2009 | Posted by Karl Beecher under News, Research |
Excellent. The journal publication I co-authored with Andrea Capiluppi and Cornelia Boldyreff (“Identifying exogenous drivers and evolutionary stages in FLOSS projects”) has now been confirmed for publication in the May 2009 edition of Journal of Systems and Software. It is currently available online. read more
Digital Archaeology
| March 10, 2009 | Posted by Karl Beecher under Research methods and tools |
Part of the use to which I’d like to put this blog is to disseminate information about research methods and tools. But before I start writing posts with involved details it’s probably prudent to present some sort of overview of the whole thing. Of course, there is no single method that is used by all… read more
Debian vs. SourceForge – Round 3
| February 22, 2009 | Posted by Karl Beecher under Research |
The tour through the comparison between Debian and SourceForge comes to a close by questioning whether Debian acts as a catalyst to evolutionary activity when a project is inserted into the repository. It has already been strongly suggested that projects packaged in Debian are recipients of significantly greater rates of activity. Of the 50 projects… read more
