The World IPv6 Day is upon us.
A handful of everyday web services such as Google, Facebook, Yahoo!, Akamai, and Limelight Networks, have turned on the use of IPv6 addresses for their servers and/or load balancers, but only for the next 24 hours or so.
Last year at work we acquired an Epson DiscProducer PP-100N as an aid for creating in-house CDs and DVDs. No more manual labour other than creating the ISO images and designing the layouts to be printed on the disc’s surfaces, and yes, placing the finished discs in their paper envelopes or jewel cases. Continue reading Epson DiscProducer PP-100N and Total Disc Net Administrator 1.21
When moving from one major FreeBSD branch to another, you are almost compelled to upgrade all of your installed FreeBSD ports. If you move from the
RELENG_7 branch to
RELENG_8, as an example, the old
pty interface is deprecated, and ports such as
sysutils/screen) must be recompiled and reinstalled to take advantage of the new
pts interface. Continue reading How to forcefully upgrade all your FreeBSD ports using portupgrade

One of the recent versions of the hyperref package (version 2011/04/07 v6.82e) crashes with the beamer document class (development version 3.10), or is it the other way around? Temporary and permanent solutions follows. Continue reading beamer and hyperref on a collision course?
My favourite editor is no doubt GNU Emacs. I spend most of my time at work using Microsoft Windows, so why shouldn’t I use this excellent editor on that OS? Continue reading My .emacs file for use with GNU Emacs 23.3 on Microsoft Windows
Tell rkhunter to ignore
/etc/passwd by inserting
EXISTWHITELIST="/etc/passwd" in your rkhunter configuration file. If you prefer not to make this change to your configuration file, make sure you run
rkhunter --propupd with the same
PATH as given in
/etc/crontab. A command like
env -i PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin rkhunter --propupd
should suffice. Thanks to Mr. Torfinn Ingolfsen for his effort to track down this problem.
