I’m in for the second time. Last time I participated in Ludum Dare was over a year ago. Since then I could find the time to do it again, even though I enjoyed it a lot! This time I however can participate and so I will.
Here is some stuff you might be intrested in and that everyone seems to post in the “I’m in” posts:

• Language: Java
• Libraries: LibGDX and extensions
• IDE: Eclipse Luna
• Graphics: Inkscape, Paint.NET
• Audio: Audacity, pixitracker, sxfr
