Unix system administrators develop their own customizations and configuration file templates over time. These customizations could be either personal customizations or system-wide customizations. Personal customizations live under each users home directory and the files name usually starts with a dot (which is why these files are usually called dot-files). And the system-wide customizations can be [...]
I was following the story of stuxnet from the very early days when it was just discovered and recently came across Wired’s very thorough story on stuxnet. Now everyone knows it was not yet another ordinary computer worm. While it might not [...]
I heard this so many times from different people that CLI in FreeBSD is much less user-friendly than CLI in Linux. But is it true?

One of the most important parts [...]
I suddenly came across this old post from 2004 in which I explained my early experiments in OS X. Now after being a hardcore OS X user for more than a year, I found how much the world has changed since. The Firefox is a really usable browser now and IM clients are up [...]
Keeping accurate time on a host (either a server or a workstation) is important because:
1- You need to know accurately when you should go for lunch or back home
2- You need accurate time in your event log files for further analysis
3- Many programs need to have the correct date and [...]
I managed to migrate my blog to WordPress after more than 5 years. I had a bad feeling about the old MT and perhaps that was the reason I was not posting too often.
I redirected the old feed URLs to the new one, but I suggest you update your links and let me know [...]
