Since I started to use the internet telephony, the Quality of Service (QoS) started to be important. When my girlfriend opened a web page, the sound was going choppy. So what I want to is:

  • Have a responsive remote terminal sessions over SSH
  • Stable VoIP telephony
  • Fast web browsing, but not hurting SSH nor VoIP

CLIPS expert system for Gentoo

I’ve created an ebuild for CLIPS, the tool for building expert systems. After submitting the ebuild to the Gentoo Bugzilla, I was told it was a duplicate and I should’ve searched. Well, I did, but I only found Eclipse related bugs and couldn’t filter them out to see this sole CLIPS bug.

Skype for Linux is dead

I've checked on the Skype forum and there are few threads about the lack of Skype development for Linux. There wasn't any new version in few (8?) months, Windows has Skype 2.0 with video support, while the latest Linux version is still 1.2 without video support, and with some long known problems unresolved.

I'll stick with Wengophone now, as the Classic version does its job and I enjoy free calls to the land-lines!

Operative mortality

Let me tell you a joke.

There was a hospital that had only one patient and the patient had died. The authorities asked this hopital to report its mortality.

“What is your mortality?”
“We have 1% mortality.”
“But you had only one patient which have died! You should have 100% mortality!”
“Yes, but we have operated him 100 times!”

Maybe this sounds funny, but this is how EACTS and STS report the mortality.
