mirrorbrain: download redirector 2.12.0 released

11 Feb 10

MirrorBrain is an open source framework to run a content delivery network using mirror servers. It solves a challenge that many popular open source projects face - a flood of download requests, often magnitudes more than a single site could practically handle.

A central (and probably the most obvious) part is a "download redirector" which automatically redirects requests from web browsers or download programs to a mirror server near them.

Choosing a suitable mirror for a users request is the key, and MirrorBrain uses geolocation and global routing data to make a sensible choice, and achieve load-balancing for the mirrors at the same time. The used algorithm is both sophisticated and easy to control and tune. In addition, MirrorBrain monitors mirrors, scans them for files, generates mirror lists, and more.

watch is one of these useful linux/unix commands. I am right now generating files that take some time and simply by typing

 watch ls -lhr

I keep the status in one screen. Really useful!

Vimperator - gain back your time

20 Jun 08

[print link all ]

Thanks to Brenden for passing me this link.

vimperator.mozdev.org/

First there was a Navigator, then there was an Explorer. Later it was time for a Konqueror. Now it’s time for an Imperator, the VIMperator :)

Vimperator is a free browser add-on for Firefox, which makes it look and behave like the Vim text editor. It has similar key bindings, and you could call it a modal web browser, as key bindings differ according to which mode you are in.

Now I need vim bindings for openoffice, so that I stop typing :w.
