Last six weeks i’ve been working on the firmware’s for the three parts of the first version of our laser tagging system. They are finished and released now, but aren’t fully tested yet.

I’ve made a little test platform to test the firmware’s. Only the PU is missing. Also i am using not that powerfull IR leds. For firmware testing this does not matter.

Google Chrome disk activity

Tuesday, September 9th, 2008

I am using Google Chrome (version 0.2.149.29) now for a few days and i noticed that once in a while Chrome is heavily using Disk IO while i’m not browsing and there’s only one website open. After each IO operation(s) Chrome uses a lot more CPU time for a second and then waits for IO again. I wonder what Chrome is doing…

Edit: After some investigating on the web it seems like disabling phishing and malware protection will do the trick.
