If you look at the current set of lv commands on most linux distros there ... http://www.kernelcrash.com/blog/reverting-lvm-snapshots/2009/12/11/ For some time now, my old Thinkpad T42 has been running as a lightweight server at home. Some people think I'm a bit mad using a laptop as a server, but my vague reasons are a) they're generally quiet, b) they don't use a heap of power, c) the battery ... http://www.kernelcrash.com/blog/so-i-bought-an-r60/2009/12/11/ My main linux box here is about 3 years old now. The case is older, but I bought the cpu, motherboard, graphics card and some of the ram when the first Core 2 Duo's were announced. It was expensive at the time, but it was well worth it. I bought ... http://www.kernelcrash.com/blog/time-for-an-upgrade/2009/11/15/ I'd read about quite a few new features in the linux 2.6.31 kernel,so I thought I'd download the official source for 2.6.31 from kernel.org and build a custom kernel on my Debian Lenny 64 bit core2duo system.

Again I somehow got it to go. I'm not too sure how good it works, but it works well enough for me at home. If you can't ... http://www.kernelcrash.com/blog/using-a-marvell-lan-card-with-esxi-4/2009/08/22/ I've been setting up an ESXi system for a client recently, and I must admit there is a lot to like about ESXi.

When I bought it (an apple refurbished model), I noticed that a lot of keys didn't register very well, and I ended up replacing the macbook keyboard. That second hand replacement keyboard has served me well for the past 10 months or ... http://www.kernelcrash.com/blog/yet-another-macbook-keyboard/2009/06/30/ Warning; The discussion below relates to my attempts to use rsync to back up a directory on a MAC to a directory on a remote linux host. I never worked out how to get it to back up 100% of all the unusual metadata that MAC filesystems include, but it ... http://www.kernelcrash.com/blog/using-rsync-to-backup-from-osx-to-linux/2009/06/20/ Google Web Toolkit (GWT)  has a great development environment using the built in jetty server, but the default setup is aimed at developing servlet style server-side programs.
