I am reevaluating my decision of becoming an Apple fan or not… And I tend towards becoming one. Just because of the excellent marketing and the excellent hardware! But the software isn’t that bad either! Mac OS X, once you get a bit used to it, might become your favorite OS! Of course, it has […]

If you’re using Windows and you have some projects synced with SVN, you could have sometimes the need to remove the folder’s SVN references.
