Mac OS(u)X

So I want to shutdown my Macbook Pro. I hit the power button, choose “Shutdown” and close my lid. Poof ! OSX decides its a great time to go to sleep. And after a few hours I open my laptop again in a hurry to start it before a meeting and what do I see ? The computer waking from its sleep, only to resume its shutdown process. Drat, let me boot it back. Sorry, ran out of battery sleeping all this while !

BeleniX 0.7

BeleniX 0.7 has been released just a few seconds ago.

http://www.belenix.org/

This is the most kick-ass version of BeleniX ever. Among the most important features is the ability to install it to the hard disk and use it as a regular desktop OS. Release Notes details the other changes:

I am just waiting for one more feature – An IPS repository of BeleniX packages and then I will make BeleniX my primary Desktop Operating System

Visual Call Graph using DTrace

Here is an example of how incredibly powerful DTrace can be. I had to solve a problem where a nice high-level overview of the code flow in a single threaded userland application would save me some pain the backside. Lo and Behold, Dtrace – The Universal Hammer for every nail.

Here is a simple visual call graph generator using 5 lines of DTrace combined with the outstanding Graphviz graphics library.

Eka in Top500

India appears in the Top 10 of the Top500 supercomputers list for the first time: http://top500.org/site/systems/2838

EKA, is a Linux cluster of Clovertown based Intel Xeon systems connected via Infiniband. Congratulations to Tata Sons and HP !

Quite shamefully, Solaris runs on only two of the Top500 supercomputers. Blame it on the pathetic HPC userspace and community when compared to Linux !

BeleniX Crazy !

The world is going BeleniX crazy ! I setup links to the isoHunt torrents on the BeleniX download page a few weeks back and the isoHunt folks responded most kindly by setting up a special box for seeding (Have you ever heard of that ?) and ran a front page article on BeleniX as a model project to use BitTorrent constructively.

As of today, the BeleniX DVD has more than 18000 (Yes Eighteen Thousand) seeds ! How many other torrents can claim as many seeds ? aXXo’s latest torrents have no more than 5000 seeds.

Is that frigging cool or what

P.S: For those who don’t know, isoHunt is the world’s most comprehensive BitTorrent search engine !
