GREAT description on customizing GRUB in order to multi-boot multiple Linux distributions/operating systems,

An excellent, 27-part video tutorial series on using SuperCollider.

Old-school free RTS. Looks amazing. Cross platform as well.

A number of free soundfonts for download.

Open-source, cross-platform software for scoring results from Scouts BSA Pinewood Derby events. Looks promising.

Freeware software for tallying results for Scouts BSA Pinewood Derby events. Windows only, unfortunately.

Here's a ridiculously fun open-source RTS game that reminds me a bit of Warcraft 2. Has single-player campaigns as well as multi-player.

First it was Cakewalk Pro Audio, then it was Sonar, and now it's Cakewalk by BandLab. Regardless of name, it's now a powerful (and free!) DAW.

Windows only, unfortunately. It also requires a BandLab account.

Yet another flat-file (no database) CMS that looks promising. This one has built-in blogging, multiple users, a media manager, and the ability to schedule posts. Oh, and RSS, too.

Another flat-file CMS that looks interesting. I believe it split from the (now undeveloped) Monstra CMS. Utilizes shortcodes and an API.

A flat-file CMS with a number of Github contributors. Has an export feature. Worth investigating.
