Finally user-friendly virtualization for Linux
Linux just keeps getting better and better. Back in 1994 it was just cool that it ran and would do PPP over my modem. Now we have KVM and other virtualization technologies.
"The upcoming 2.6.20 Linux kernel is bringing a nice virtualization framework for all virtualization fans out there. It's called KVM, short for Kernel-based Virtual Machine. Not only is it user-friendly, but also of high performance and very stable, even though it's not yet officialy released. This article tries to explain how it all works, in theory and practice, together with some simple benchmarks."

SSH your Debian servers without password
Secure Shell is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over unsecure channels. It is intended as a replacement for telnet, rlogin, rsh, and rcp. For SSH2, there is a replacement for FTP: sftp.This might be useful if you are trying to connect everytime to your server remotely. Read Full Story

Apache and Lighttpd configure mod_rewrite
Here's a nice howto on using mod_rewrite under Apache and Lighttpd for temporary site outages. This tip will help you to disable a site for maintenance using mod_rewrite without redirecting url.

Mac Carputer
Nice series of articles describing building a very cool car computer from a Mac Mini.
"Todays package from UPS completes my collection of parts that will be required for my car computer install. I already had the mac mini, and today I got the screen, the custom bezel, the power supply, and an adapter cable I need. I will just need a few more little things from the hardware store to complete the install."

OpenVZ On Debian Etch For Webservers
Virtualization is a good practice for servers, since it makes things more secure, scalable, replacable, and replicable, all this at the cost of little added complexity. This guide was written during an install of a Supermicro machine with two dual-core opterons (64-bit), two identical disks (for RAID) and a load of memory. Why OpenVZ and not XEN or the recent KVM kernel module? Well, XEN is not very stable for 64-bit architectures (yet), and it comes with quite a bit of overhead (every VM runs its own kernel) due to its complexity. KVM is very simple but restricts you to run a kernel as one process, so the VM cannot benefit from multi core systems.

Why ZFS Matters to Mac Users
Nice explination of what ZFS is and why it matters to us.
"This description totally misses the point of ZFS, focusing on a number that means less than megahertz for CPUs. I imagine that most Mac users who haven't been following ZFS development incorrectly assume that ZFS probably doesn't matter to them unless they are running some sort of Xserve server farm. Nothing could be further from the truth."
