"Gitsum provides a mode to do interactive partial commits with Emacs. Run `M-x gitsum' inside a Git repository and kill everything you don't want to commit with `k'. You can navigate easily between hunks with `n' and `p' and between files with `N' and `P'. A whole file can be killed with `K'. If you want to refine the patch, you can split it with `C-c C-s'. If you toggle read-only with `C-x C-q', you can edit everything freely (be careful!)..." -- http://github.com/chneukirchen/gitsum

"NimbleX 2008 Beta has finally been released! After many months of using it, I finally decided is good enough to be released as a Beta version of NimbleX 2008.

RPM Fusion aims to end the confusion over 3rd party repositories and Fedora by merging Livna, Dribble and Fresh RPMs: they hope to be a one-stop shop for all the extra packages Fedora can't ship by default for various different reasons.

Most home computer users think of servers as the complex machines that form the backbone of corporate computer networks. But the functional definition of a server is far more flexible than that. Essentially, any computer that “serves” data to other machines on a network is a server. And as American households become populated with multiple PCs, the idea of a central hub that can be used for backup, storage and even remote access becomes reasonable, even essential.

FlyBack is a tool similar to Apple's TimeMachine. It is intended to create snapshot-backups of selected directories or even your full hard drive. From the FlyBack project page: "FlyBack is a snapshot-based backup tool based on rsync. It creates successive backup directories mirroring the files you wish to backup, but hard-links unchanged files to the previous backup. This prevents wasting disk space while providing you with full access to all your files without any sort of recovery program. If your machine crashes, just move your external drive to your new machine and copy the latest backup using whatever file browser you normally use." This article shows how to install and use FlyBack on Ubuntu 7.10 (Gutsy Gibbon).
