Now With Extra Added Fellowship

English
 

Last week I was surprised to receive an email from Shane Coughlan inviting me to become a Fellow of the OpenForum Academy. The current Fellowship has some of my personal heroes in there and so it was exciting and humbling to receive such an offer.

From their website:

Cyrus IMAP: What Happened When They Switched To GIT?

English
 

So recently Jeroen van Meeuwen asked me to take a look at Cyrus IMAP. He had been involved in their switch from CVS to GIT and was curious to see what the results looked like. Let’s start with the usual green blobs:

Getting Cohesive

English
 

So, in my mission to see how we can automatically detect “core” teams, I need a measure for how closely people work together. Those of you with strong memories will remember I once coined the term “cohesion” for this measure. I introduced it in a paper at the International Conference on Software Maintenance, three years ago and blogged about it around that time.

KDEPIM: A Little Look At 2011

English
 

So this is about the time I usually do my annual review of activity in KDE SVN. Of course I have now stopped my analysis of KDE SVN and moved on to git. Instead of analysis every repo in KDE git, I will focus on what happened in KDEPIM in 2011 (KDEPIM exclusively, no PIMLIBS or PIMRUNTIME).

OK, to kickoff, the green blobs (click to enlarge):

Collatz Conjecture: Dabbling with Python and Graphviz

English
 

[This is slightly off topic from my usual Free Software analysis.]

So the Collatz Conjecture came to mind. I took a look at the Wikipedia article and was struck by a couple of things: I liked the stopping time (the number of steps you have to take to get from the given starting number to 1) plot and the graph showing the paths from certain starting numbers to 1.

Delving Into Git (KDEPIM)

English
 

OK, now KDE is 15 years old, it is time for my work to grow up and start looking at git. One of the questions I get asked from time to time is how much code rewriting I will need to do in order to for with git. Thankfully… none.

All of my scripts parse SVN logs and it is easy enough to get git to give back logs in SVN format. Just like this:

git log –reverse –format=”<logentry revision=\”%H\”>%n  <author>%ae</author>%n  <date>%ci</date>%n</logentry>”

So What Does 15 Years Of KDE Look Like?

English
 

So, I thought I would take a quick look at what KDE community “looks” like after 15 years under development. So here I will briefly show off three visualisations with no particular comment. I will just leave them here for your amusement.

So let’s start with the now-infamous green blobs (click to enlarge):
