Java Timezone Information 2011g … The community release is here :)

Egypt has recently stopped working with DST time, so we need to update our timezone information with the latest updates, as a normal user for java, I used to download the TZUpdater tool which was always available for free from SUN … But not anymore, as Oracle started to show its ugly face, if you [...]

Brain Dump…

Today, a friend of mine and I had some wonderful time… Not skiing, not playing a game, not chasing beautiful women, but rather chasing awesome thoughts, reverse engineering, and cracking into some software, and here’re some ideas… In fact the idea of having a page containing such content (as this one) and calling it “Brain [...]

Amazon Kindle, Working around regional restrictions…

Few weeks back, a friend of mine was visiting the US for some business of his own, and I couldn’t help to ask him to bring back an Amazon Kindle for me… I choose the cheapest model, the one with the WIFI only, with 6" screen, it seemed satisfactory to my needs, I won’t need [...]

Privacy becomes more precious everyday, and so does Open Source…

Yesterday I was visiting my friends in ITWorx, and they were totally bugged by the new gateway that the IS has installed to monitor and control users’ access to the internet… That new gateway is called “Thread Management Gateway” from Microsoft, and guess what? it SUCKS, BIG TIME… Their 1st impression that it made things [...]

More Steps ahead…

Another step ahead… RTOS…

Yesterday I finished a training course that was about RTOS, the instructor was Amr Ali, and Wasiem Hashim, the course covered some topics about RTOS, concepts, scheduling, threading, synchronization, and best of all, concepts of porting… It turned out that I know much already to get me started, and already have the foundations I need [...]

A quick glance about filesystems…

Cluster vs. Distributed Filesystems Cluster filesystems and distributed filesystems are two different things, but sometimes they’re mixed together, so it’s time to shed some light on that…

Anaconda boot time options…

In a previous post, a friend replied that I didn’t really need to modify initrd.img to embed ks.cfg just because I can’t use eth0 … He was totally right, I’ve gone through much without looking for the easiest and obvious… http://fedoraproject.org/wiki/Anaconda/Options, this page has all the options that anaconda (the installer for CentOS/RHEL/rPath and more) [...]
