red (pronounced "ready"): An attempt.

View source(pretty printed) -- Plain

A lame attempt at doing what ReadyBoost does. But really, this is more like a spoof on ReadyBoost. I guess code parody is the next big thing? If so, here is an early submission.

red: A script that tries to emulate what ReadyBoost does (but not quite).

apt-o: The "oblivious" tweak.

View source(pretty printed) -- Plain

We all know of apt-get and apt-cache. Having used Fedora and living in the yum world, I wasn't aware of which command belonged to apt-get or apt-cache specifically. Thus, apt-o. Now you don't need to know which verb command like "search", "install" or "update" belong to what apt-*? the syntax simply becomes: $ apt-o search xmms or $ apt-o update and so on. Srichand (of Java-GNOME fame) further tweaked the code to get rid of the things which were not required and added those that he thought were.

To install: chmod +x apt-o -> su -> mv apt-o /bin/

get-servers.py

This is very much work-in-progress. It gives you a list of sorted servers based on the round trip time from your system to them. get-servers.py, as of now, probes PlanetLab nodes (320 servers distributed across the globe) and returns the sorted list.

Automated Tomcat installation for network-wide systems.

Something Srichand and I wrote back in 6th sem (I think). Was used for "Java/CGI Lab" at MSRIT. Since going to each system and installing it manually would be cumbersome, this shell script was written.
