If you’ve committed some code into to CVS, and made a mistake on that commit, you will want to know how to revert to a previously saved version. Here is the command line command for CLI versions of CVS:

$ cvs update -D '1 week ago'

Run this command in the main directory of your checked out working copy. This will revert your working copy to the version of the code that was checked in ’1 week ago’ from the present date. You also use commands like “1 day ago” and “5 days ago”.

Then simply commit the changes with a log message:

$ cvs commit -m "Oops! Made a mistake, had to revert back to the 21/1/2011 version"

I’ve been writing some simple Java GUI applications using the Netbeans IDE. It allows you to quickly make event-driven GUI applications, and generates a lot of skeleton code that you’ll need, but don’t necessarily want to type out. It reminds me of the IDE designer of Visual Basic 6, which allowed you to mock up simple GUIs with code in almost no time at all, although the VB language itself often proved difficult. With Netbeans you are using Java, and so you can make some powerful software with little effort.

Lately I’ve been thinking about making a Flash game or application. Although I haven’t made one yet, my current understanding is that most projects of this type require a lot of artwork.

I found this article, and was impressed at the quality and the resources mentioned: http://freelanceflashgames.com/news/2009/03/25/the-big-guide-to-hiring-an-artist/

I’m going to take a break from the purely technical posts to get more people to see this video. Here the late Dan Osman speed-climbs a cliff without any safety equipment.

Risky? Just a bit. A few years later he lost his life during a similar attempt. But no-one can doubt the guts required, and the level of skill he achieved, in this type of climbing.
