Yesterday I wrote about my search for a hosting provider for a Xen DomU [1]. One response was the suggestion to run a Dom0 and sell DomU’s to other people [2], it was pointed out that Steve Kemp’s Xen-Hosting.org project is an example of how to do this well [3]. Unfortunately Steve’s service is full […]

I’ve been trying to get ipsec to work correctly as a basic VPN between two CentOS 5 systems. I set up the ipsec devices according to the IPSEC section of the RHEL4 security guide [1] (which is the latest documentation available and it seems that nothing has changed since). The documentation is quite good, but […] Matt Bottrell has written about some issues related to the acceptable weight of laptops for school use [1]. Matt cites a reference from the Victorian government stating that a school bag should not be heavier than 10% of the body weight of the child who carries it [2].

Now choose a suitable Ethernet MAC address for the interface (see my previous post on how I choose them [1]). […] The way Xen works is that the RAM used by a virtual machine is not swappable, so the only swapping that happens is to the swap device used by the virtual machine. I wondered whether I could improve swap performance by using a tmpfs for that swap space. The idea is that as only one […] TED has a post about the design of the new OLPC [1]. I never liked the previous OLPCs [2], for my use a machine needs a better keyboard than the tiny rubber thing that they had. I understand why they designed it that way, for use in places where it would be an expensive asset […] |
