OK, this is the coolest thing ever – I decided to download the beta for the upcoming Ubuntu Precise Pangolin (12.04 LTS) release and do some testing. And I start installing it in a VM, and *while* it’s installing, I see it populate a dialog with Ubuntu-relevant links, and curiously, I click one… and BAM, [...]
I just finished the LibreOffice Impress presentation I’ll be using when I give my first Linux Sysadmin 101 talk at IT-ology this weekend. The hardest part is always making graphics!

It’s licensed Creative Commons non-commercial share-alike; if you’d like a copy, you can grab one [...]
As a proof-of-concept for USC computer science labs, I set up eight Windows 7 VMs on the same physical host in the Windows Server demonstration below, and recorded firing them up simultaneously and doing some light web browsing, etc. on several of them. Performance is pretty solid; you could probably cram double this many [...]
I’ve been surprised and pleased at just how well Windows Server 2008 runs virtualized under Debian Squeeze. I first started running virtual Windows Servers purely for the disaster recovery and portability aspects, expecting to pay with a drop in performance… but what I found was that in a lot of cases, Windows 2008′s performance [...]
One of the things that I’ve missed on the Linux desktop is simple audio tone control in the sound volume applet. It particularly annoys me that Gnome allows you to set cruddy little reverb profiles (wow, all my audio sounds like a dog barking now… uh… thanks…), but if your speakers need a little [...]
Another consultant emailed me a .evt file recently for review. Which is great, except I frequently go days now without sitting in front of a Windows workstation – or at least, not one that isn’t broken and in need of fixing. So, I needed to find a Windows Event Log viewer.
There isn’t currently [...]
If you have to deal with foreign languages and character sets (Cyrillic, Katakana, Hiragana, Kanji, etc) you need to have UTF support on your server. If you don’t already have it, here’s how you get it:
1. nano /etc/default/locale.gen and uncomment the line with en_US.UTF-8 (assuming your default language should be English)
2. locale-gen
3. edit /etc/profile [...]
The performance of the built-in RDP clients in Ubuntu as of 10.04-LTS Lucid Lynx (and previous) is plagued with difficulties – Windows machines, among other things, frequently have events which refresh the local desktop every second or so which Windows’ native RDP client doesn’t trigger on, but for some reason the TS Client and Remote [...]
add a Router block to the end of /etc/exim.conf.local:
@ROUTERSTART@

If you’ve never seen a machine equipped with a good Solid State Drive (SSD)… they’re pretty impressive. In this clip, I’m putting an Ubuntu 9.10 workstation with an Intel SSD through its paces.
Some of the reason that machine is so fast is Ubuntu – the newest release has some pretty significant disk speed related enhancements [...]
