Unix/Linux hacks and confs

I haven't had time to blog for a while, but I have an arsenal of Unix hacks to post about, so just stay put fellas. The world of Unix Linux is turning into virtualization, it seems. This has it's pros and cons of course, mostly pros in my opinion, as you will need less servers to provide your services. The investment will also be greater, at least initially, as virtualization can be rather expensive. But if you are administrating lots of servers, this might be worth the extra bucks, as the administration will be much easiser and smoother.
