This post is part of  a series on Git and Subversion . To see all the related posts, screencasts and other resources, please  click here .  In preparations for presenting "Living with Git and Subversion in parallel" at GearConf  in a few weeks, I've been practicing a Git+SVN exercise, going through all the steps from Git-cloning a Subversion repo, to full centralized Git-SVN mirror. While I was doing this, I figured I might as well make some more use of this, and record some screencasts as I go along. I've just posted the first three on YouTube , and collected all my various works on Git and Subversion on this page . Feedback is much appreciated! Update: I'll try embedding the videos here on the blog too: Git+SVN #1: Cloning a repo Git+SVN #2: Some commits back and forth Git+SVN #3: Conflicts

I recently did a lightning talk at the local Java User Group in Cologne. Topic was  Agile in a Year in 5 minutes , a shortened version of the talk I did earlier at FrOSCOn. I'm gonna be doing the full talk at the Cologne JUG on the 8th of November, so be there! Well, if you're in the area, anyhow.

Some time ago,  Ole Morten tried a concept called MyWeeklyLinks , but he stopped after the eighth one. I speculate this was because he defined an audience that had no need for this kind of information, namely us: his readership. We rely on Twitter, blogs and other community-driven sites (Digg, Google Reader, DZone) for the fitting stream of links we consume. That's not to say that that weekly links is a useless practice. Remember that you, dear readers,  are "information power users": We like to stay on top of what's going on out there, we stay updated. We devote a certain amount of time for this activity. Perhaps we have no need to consume "weekly links", but we can produce it for our colleagues. I wrote my first mail like this to the team mailing list little over a year ago, simply three links: Hi folks, I just wanted so share some interesting resources I found the last few days:   This is a short overview of some Java programming styles that can g...

In the newest Javamagazin , there's an article by Bastian Helfert and Steffen Hohn about CodeCity , a really interesting tool for visualizing code. I just ran it over our 300k LOC Java project, and got this model ( click to see larger version ): Buildings are classes.  Height is based on class LOC Building ground-area is based on number of attributes City blocks are packages. If you actually run the program, you can interact with the model, fly around, click to see which package is which block, etc. This is all fun and cool-looking, but does it have any practical usage, I wonder? I think we want to work in small friendly villages, where most houses are evenly-sized, nicely sized neighborhoods, no big ugly gray parking lots, and no towering sky-scrapers. Here I ran it again on a smaller, nicer project: Certainly a lot easier to find your way around this neighborhood. I know Michael Feathers has made quite a few thoughts around code aesthetics . Perhaps ...

After tirelessly blogging about how to work with Git and Subversion in parallel for some time now, I fired off an abstract to GearConf , as this looked like a subject that would be right up their alley (they had talks about Git and Mercurial last year). They accepted the talk a couple of days ago, so it looks like I'll be driving up to Düsseldorf on the 11-12. October. Interestingly enough, GearConf is sharing the event with the Atlassian Software Conference Düsseldorf ,.  I've been up close and personal with their products before , so it'll be cool to see how far they've gotten since back in the day (when their products were already awesome). For anyone in the area, the people behind GearConf are also arranging  WebAppDays  in Düsseldorf from 27-28. September. I would go there too, but I think I'm all out of conf-days for this year :)
