Home video security with Zoneminder and Ubuntu

by

zoneminder logoThis weekend my colleague brought to our office simple 20$ webcam. I have to say that my previous attitude to such toys was quite ambiguous. But idea to build home/office video security system based on such webcam(s) and Ubuntu changed my mind especially taking into consideration extremely low cost of end system and it’s capabilities. First of all I was interested in events replay, multiple camera zones and web interface. As it was discovered later, such system provides tons of useful features.

ubuntu logoIn this post I’ll provide you with a free-style guide on how to set up home video security system that supports above mentioned features and is based on rather cheap webcams, free as beer software ZoneMinder and Ubuntu. I used Hardy Heron Ubuntu (8.04) for the installation but this guide should also work for 8.10 (Intrepid Ibex) and Jaunty Jackalope (9.04).

Adjust LCD brightness from command line

by

As many other Ubuntu users several days ago I’ve upgraded my Feisty to Gutsy at my Dell Inspiron 1501. Unfortunately many things that worked for me in Feisty doesn’t work in Gutsy just after upgrading. Among them are: suspend/hibernate and brightness adjustment. At this moment I’m trying to get these features working and certainly share results here but not workable brightness adjustment really disturbed me. So, until I didn’t find a solution how to adjust LCD brightness with keyboard, there is nice workaround: execute the … Read more

Linux + 8*PS3 = Cluster for gravity simulation

by

[digg-me] A certain Gaurav Khanna from University of Massachusetts Dartmouth created computing cluster based on 8 (eight) Sony PlayStation 3 consoles that is meant to simulate gravity processes. The project is named as “PS3 Gravity Grid” and allows to model Binary Black Hole Coalescence using Perturbation Theory. Actually it’s not first case when PS3 is used as a component for cluster as it has not bad Cell Processor and it’s open platform. How do you think, what operating system manages cluster? Windows? Nope. It’s Linux. … Read more
