Happy New Year 2013!
We’ve managed to avoid devastation just days prior to Christmas as the Mayan calendar took a new turn. We’ve even survived celebrating the New Year, although some of us weren’t so lucky due to careless handling of fireworks. If you’re into computer science, then Don Knuth‘s 18th Annual Christmas Tree Lecture entitled “Trees and chordal […]

Sometimes the default location of the Client-side Caching database is just plain unsuitable. Client-side Caching, or CSC, is used for storing offline files, local copies of files normally stored on Windows shares, stored on Windows servers. (The Norwegian term is «frakoblede filer».) The default location for the CSC database is C:\Windows\CSC. If you like to […]

Today, I decided to upgrade PostgreSQL from 9.1.5 to 9.2.0 on one of my computers. Ironically, PostgreSQL 9.2.1 was released today, but until the FreeBSD ports hierarchy catches up, the most recent version available is 9.2.0, unless of course you want to do everything yourself.

An acquaintant posted the following question on an IRC channel earlier today: How many IPv4 addresses are there? The quick and simple answer is 232 = 4,294,967,296 addresses.

ICANN #44 is taking place in Prague these days. Sadly I was unable to attend, but the presentations are available in the open. Today’s IPv6 session would be the highlight in my very biased opinion.

I have wondered what emails sent from smartd would look like. Interestingly, I received such a sample from one of my systems a couple of days ago.

Someone found my old ZFS snapshot script rather useful and wanted to improve it. Unfortunately I used the GPLv2 license in the original script. To accommodate my friend, I have re-released the snapshot script under the 2-clause BSD license. Feel free to use whichever license, 2-clause BSD or GPLv2, that suits your needs.

clang is a breath of fresh air when it comes to deliver meaningful diagnostic of errors in program code. Not only is the diagnostic colourful on screen, clang also points out where in the source file changes ought to be made.
