VMWare ESXi Vsphere
May try moving my Xenserver setup to Vsphere to allow me the option for PCI passthrough, which Xenserver doesn’t offer.
This is a great guide (for both hardware and installing) ESXi 5 and setting up UnRaid on it, which is what I plan on doing as well.
The case my current unraid server is in has more then enough space for more drives, (just need another drive tray) and I’d be good to go. I am already running out of ram in the current Xenserver system so to try and upgrade the DDR2 ram in that box would cost a lot of money. Probably as much as getting a new system built uing DDR3 ram (yes, it’s that much cheaper right now). As an example, I just upgraded my desktop machine and for the cost of getting 4gigs DDR2 ram, I got 8 gigs DDR3 ram + a new motherboard.
I’d probably want 16gigs of ram in the new system, (going from 8gigs in the xenserver box). I just need to choose components as apparently ESXi is a little more picky about hardware then XenServer (which seems to run on pretty much anything)

Casting plastics
Excellent read on one man’s journey through 6 years of experimentation with making plastic parts:

ZFS for home storage, and backups
I took the plunge and moved part of my home storage to FreeNAS using ZFS to manage the files on it.
Now comes the tough part of managing a file system I know nothing about how to use (which on paper seems excellent).

Virtualbox installation on openSuSE
I keep having issues every time I install VirtualBox on my machine, and figured this time I would document what I did to get the kernel modules to properly compile upon installation.
First make sure openSuSE is up to date
zypper update
Then install kernel sources
zypper install gcc make automake autoconf kernel-source kernel-syms
Adding delay
So adding a capacitor and resistor in series, adds a delay.
So for a 0 .1 sec delay, I need a 100μF capacitor and a 1kΩ resistor.
For a 0.5 sec delay, I need a 100μF Capacitor and a 5kΩ resistor.
