Back in the days where I used Windows having video and audio conversations with Skype was really easy. Just plug in all the devices and configure the volume of the microphone and you are done.
Today I tried the same with my Ubuntu 10.04 installation and I encountered a few problems. This is how I got my webcam working with Skype: continue reading…
A while ago I used VMware server to running a few virtual instances for testing purposes. Everything worked really flawless. Yesterday I wanted to have some virtual server on my home computer again and encountered many problem with the current version of VMware Server on my Ubuntu 10.04 LTS.
There where some problems with the installation, some to get the VMware console running and also a few the keyboard input on the console.
It took a while to get everything running and I pulled all the information I needed from many different sites. So pulled them all together in this blog entry: continue reading…
In my last post I wrote about some problems that I had with my virtual server that freezes under heavy load. The improvements I suggested worked really nice but the server still sometimes freezes – not often as before but it still happened. So I “googled” around and also asked at ServerFault.com.
It seems that keeping up the the apache mpm_prefork and mod_php will not be the solution anymore. Most sites suggested to use mpm_worker instead, because it uses less memory (and my problem was, that my Apache consumed all my memory). On the other hand there could be some problems with thread-safety, but I liked to give it a try. PHP will not me used as an Apache module any more.

On the last blog I wrote for was an article which described who to install eAccelerator on a Ubuntu server. As this blog entry had a lot of visits I decided to put it on this blog again:
PHP is not the fastest scripting language, that truly a fact. Except from optimizing the scripts there a few possibilities to speed everything up. One is to install a byte code optimizer and cache on your server. They cache the byte code created by the PHP parser and try to optimise it. So every time some one requests for a page on your server the script does not have to be parsed again. This brings a speedup of 120 – 250% depending on you script. There are several byte code caching program available, the one I like most is eAccelerator. Sadly eAccelerator is not available through the Ubuntu repositories so you have install them yourself. Here is a short description how to archive this!
