Linux Conf Au 2011
If you missed the chance to participate in linux.conf.au this year or, like me, you’re thousands miles away from Down Under then this link http://linuxconfau.blip.tv/ would help you stay tuned and feel the pulse of Linux kernel development.

Set a limit on a process’s size
At times it’s require to limit a process’s memory size by some value. In such cases “ulimit -m” is our best friend. But what if the task to limit not only a certain but all processes on the given system. I didn’t know how to do that, and frankly speaking have never faced with such […]
How to create many ifcfg-ethN files in one shot
I had a quick task to create 254 ifcfg-eth1:N configuration files for a Linux installation and certainly spending the whole day doing that manually wasn’t part of my plan. Here is a quick and dirty one-liner I used for that:

I know it’s a lame excuse but the last few weeks were indeed very hectic not only because I’ve joined a freelance community but mostly because I was snowed under on my permanent position. Anyway, today I’d like to guide you through the steps required to migrated […]
Ominous gap in pmap’s output
I couldn’t help posting this link which is a must-read if one day you notice that there is something uncanny in the way pmap depicts memory layout of any process under Linux x86_64: # pmap -x `echo $$` 28917: -bash Address Kbytes RSS Anon Locked Mode Mapping 0000000000400000 712 – – – r-x– bash 00000000006b2000 […]
