• Hacksgiving Left-overs

  Last week we hosted our first Hacksgiving event, a two-day virtual hackathon with a number of recorded sessions and plenty of pull requests submitted, I would say it was a success!

• Celebrating Hacksgiving!

  Next week in the US we have a national holiday where, generally speaking, lots of turkey gets converted into left-over turkey sandwiches. For many software developers the Thanksgiving holiday also represents a lull in project schedules, freeing up some time to hack on pet projects or even contribute to open source projects. Taking a cue from the Adopt a Plugin program...

• What JVM versions are running Jenkins?

  Preceding some of last week’s Jenkins 2.0 discussions, there had been some threads on whether we should move Jenkins to require Java 8. The introduction of Java 8 last year brought performance improvements and highly desirable API changes, which make developing Java-based applications (arguably) much easier than before.

  With more than a thousand public plugins in the Jenkins community now, it should come as no surprise that some of them are no longer actively maintained.
