Running a Genetic Algorithm on an Amazon EC2 Cluster

I've started working on a simple tool to run genetic algorithms on a Linux cluster. I'm using MIT's StarCluster utility to create an on-demand Linux cluster on Amazon's EC2 cloud computing service. Using this as a starting point it should be pretty easy to deploy as much computing power as I want (budget permitting).

Step one was Amazon Web Services ( sign up. I already had a normal Amazon account,...

Kate indentation

Posted 09-27-2010 at 07:36 AM by robertvi

One of the most annoying things for a programmer is a text editor which is trying to automatically

I'm using Kate version 3.4.2. [Jump to the summary at the end if you're in a hurry]

today I took the disk (see previous post /questions/blog/robertvi-358970/problems-with-new-external-hard-disk-1711/) back to the shop with my receipt, and a helpful attendant plugged it into a windows laptop there, and noticed that it said "this device can perform faster" meaning that it was only working as a usb1 device (uhci, not ehci) under windows as well. so i swapped the disk for a 320GB one, after she first checked the new disk by plugging it into the windows laptop.

at home, I can...
