IntelliJ IDEA 9 Subversion Functionality Is Buggy as Sin
21. February 2010
I already blogged about running into problems with IntelliJ 9’s SVN operations once before, and here I am again, unable to check a goddamn thing into my repository because it’s done it again “Checksum mismatch while updating…”
Previous to this error I tried to commit 10 changed files that had a refactored common method in them [...]
How I Fixed the “Subversion Checksum Mismatch” Issue
13. February 2010
From where I’m standing SVN seems to bring with it a lot of the issues that CVS had with regards to “too much” changing on your local disk and then that getting you into trouble when you went to check it into the repo.
I never figured out why exactly CVS would frequently balk at this [...]

10. February 2010
I’m documenting this issue (and fix) here for anyone else Googling for an answer. I just did for about an hour and found no answer, but instead stumbled across the solution.
If you are using anything from the javax.xml.stream packages in Java 6 or later, you are using the Sun Java Streaming XML Parser (SJSXP) implementation [...]
Did You Know enums Can Define Their Own Methods?
20. April 2009
… I sure as hell didn’t, but found myself in a position the other day where I was thinking “Damn, I wish I could define a common method in this enum that I could call and not have to write another utility method…” Well, ask and ye shall receive… or something like that.

Huge thanks to Marc Chung for sending along this great reference.

25. January 2009
As a beginner to the Ruby language, I often found myself needing feedback listing which files are in a given directory. Ruby, for that reason alone, has been a quick savior. A couple of Google searches on this topic will land you somewhere near the Ruby class Dir. Dir is a part of the [...]

If you haven’t heard yet, there is good news on the application development platform front. Recently Qt Software, owned by Nokia, announced that the next version of their flagship product, QT 4.5, will be distributed under the LGPL.

4. January 2009
It has been a while since I’ve had a chance to play with Ruby, and with 1.9.1 coming out in January I figured I’d go ahead and install 1.9 to get a feel.
Since speed was always an issue in 1.8 I figured I’d re-run my fib.rb script to find the fibonacci number for 35. [...]

A couple weeks ago I wrote an article on a fantastic framework called Play!.
