Sikosis sent me this cool link for an easy to fold origami cd holder. Thomas Hull also has a PDF of the same folds.
This has much better side designs than the one I used to fold. I’ve already started improvising with the slide in tab area.

HostIP have a firefox plugin to let you know where links are physically hosted. There is also an API which makes it easy to lookup the host location without having to store that huge database of locations.
I thought that qmail was a nice and simple mail server that did the job. At least it’s never given me any grief.
A server that I admin has grown it’s data to the size of the partition holding it and needs a reinstall to change the partition size.
On investigation I’ve found a lot of qmail detractors extolling the virtues of postfix. The bookshelf within reach features more than a casual mention of installation procedures etc, so I think I’ll be up for auditioning postfix with dspam to replace qmail.
It always amuses me when I read a tech article that creates it’s own set of example domain names, when RFC 2606 gives us a way out of the confusion.
ipband is a pcap based IP traffic monitor. It tallies per-subnet traffic and bandwidth usage and starts detailed logging if specified threshold for the specific subnet is exceeded. If traffic has been high for a certain period of time, the report for that subnet is generated which can be appended to a file or e-mailed. When bandwidth usage drops below the threshold, detailed logging for the subnet is stopped and memory is freed. ipband man page.
Also useful for simliar stats is tcpstat.
The advent of home robots isn’t far away. Check out the new 914 series from Whitebox robotics.
“Unleash your imagination with this revolutionary new open-standards robotics platform from White Box Robotics. Create your own one-of-a-kind machine from readily available, off-the-shelf PC parts…we invite you to Dream in White.”
Review here. “In all fairness, this is a new product that’s creating an entirely new segment in the PC & Robotics industries (yes PC-Bots). People need to understand right off the bat that the 914 has all… and I mean all the functionality of a PC. Hook up a monitor, keyboard and mouse to the 914 and you could use it do your homework, answer emails, surf the web etc., connect to speakers and you could listen to your MP3 collection.”
“On top of that it is a mobile robot. Yes it looks like R2D2, and yes it comes with software beyond the OS that can enable movement and navigation and more”
After trying Nagios a year or two ago, I stopped using it because it was too much effort to update all the various config files to make it work.
Zabbix is a simple monitoring package that allows you to interact entirely through a web interface to add hosts (BSD or W32), the items you want to track from that host, triggers to send you email, graphs of combinations of items, screens of selected graphs and more.
