How not to make coffee

In the past few weeks we've had a number of humourous (and dangerous!) coffee experiences such as mixing boiling water in the coffee grinder, turning the coffee maker off after the first cup, etc etc.

Here's a picture of today's coffee.

Online storage with Box.Net

Signed up for a free account with box.net today. You get 1GB of storage space with the limitation of 10MB files.

This size limitation on the "free" account is a little annoying, but it's easy enough to split my files first.

We'll see if I'm still using the service in a month.

Some benchmarks

Did a few simple benchmarks on a couple of FreeBSD machines at work that are used to VPN our Hamilton & Toronto locations.

Been offline for some time

Just writing to say that I haven't abandoned this blog. Just with work full time, and family full time, I haven't found the time (or motivation?) to sit down and write anything of substance or worth in a while. Here's a quick list of things that have happened in the past few months:

• Winnifred started pre-school
• Started work full-time
• ...
• That's about it

Well, the list is rather small and not very impressive, but its contents have been keeping me very busy!
