A Strategy Game in Linux Environment, 0 AD (zero-ey-Dee)

Tweet

If you are fond of strategy game, 0 A.D. (zero-ey-dee) is one of the best game, which is available in Linux (also in Windows and Mac). It is a free, open-source, historical Real Time Strategy (RTS) game.

The game winning secrets resembles with the “age of empire 2,” i.e., build more and more modern weapons and attack as soon as possible. Defensive strategy hardly works.

However, currently it is available only in alpha version, by Wildfire Games. Even though it is in alpha phase. I have tested and it is working well in Ubuntu 12.04 LTS except the movement became very slow in some missions.

0 AD provides a platform not only for playing game, but also we can build a scenario and map ourselves. Here are some print-screens.

Is Debian the Most Stable Linux Distro?

I have been using Fedora for many years. Fedora is the leader out-breaking new software. I have found many research related software are more comfortable in fedora than some other Dostros, which I have tested. But the greatest drawback of this OS is the instability and crashing of several times. Surprisingly windows 7 showed great improvement, however, it is not freeware.

Because of YUM and RPM system and is bluish configured, I had shifted in CentOS. Although CentOS is designed for server, it was good in desktop also. And I could install research related software and they were working well, however, not good for Skype. But when I made update a few days after installing 6.3, the system did not start. There was no facility for bug report at that case. It booted only and hanged on log in screen. I had restarted several times but same problem persisted.

Then I tried Linux Mint. I surprised with its awesome feature. Really, it was very good looking. But yesterday when I updated Linux Mint 14, Nadia, I got the same problem as CentOS. Does it mean Linux OS are still in infancy in terms of reliability and stability.

Probably, I have to try Debian but may I install the latest version of some software such as Libreoffice, VLC, Autodock, Chimera, etc.

At this stage I need such Distro, which is stable for at least for 2-3 years without compromising for the latest software and security. I mean the software / application could be installable a few months later than the final release date, if not immediately. Please comment if you have any idea.

No doubt, Nepal is one of the poorest countries, however, our education and courses, syllabus is still competitive. Further study in reputed university is very difficult for us because our government never supports for any scholarships, unlike other developing countries. Here are some websites where we can find some lectures offered by MIT, Harvard University, etc. These are absolutely free. Though, we have very slow internet and limited time of electricity supply, still we can try.
EdX (Most of the courses are about electronics, computer, physics, etc.)
Coursera (This offers a wide range of courses including physics, computer, biology, etc.)
