Well, even after many years of using Linux, I can still learn new things every day. What I learnt today:
Raising Skinny Elephants Is Utterly Boring
The reason I never used this keystroke sequence so far might be related to the fact that Linux almost never crashes ;)
As you’ve probably noticed, I’ve finally managed to migrate the posts and comments to the new publishing software (which is WordPress, mainly due to the fact that it can be conveniently kept current using Gentoo’s portage system). The outgoing links/blogroll is still not migrated though (as I don’t have them ready in an OPML file for easy importing) – it will be done ASAP.
Note that links of RSS/XML/Atom feeds and of the blog itself are not necessarily final yet (expect some changes during the next couple of weeks)
Stay tuned and thanks for your patience!
Dani
P.S. If you’re wondering: The design of the blog will be migrated too, of course ;)
If you want to deny public access to a parent location (let’s say /projects/), but allow public access to a sub-location (/projects/myproject/), use the following statement in httpd.conf:
<Location /projects>Order allow,deny</Location> <Location /projects/myproject>Order deny,allow</Location>
(can also be used for <Directory> statements etc.)
Note that the URL of the sub-location must include a trailing slash (e.g. “https://news.numlock.ch/projects/myproject/”)
FireBug is a new tool for Firefox that aids with debugging Javascript, DHTML, and Ajax. It is like a combination of the Javascript Console, DOM Inspector, and a command line Javascript interpreter.
In preparation for an upcoming Java EE project, I’m also doing some advanced GUI prototyping using DHTML, Javascript (and eventually AJAX, where it fits in). FireBug comes in handy :)
The -vt option of emerge is very useful for finding strange dependencies when doing world updates. E.g. when the question is “Which ebuild is causing X11 to be installed on my headless server all of a sudden?”. Just add -vt to emerge -puD world:
emerge -puDvt world
..and take a look at the root of the relevant tree. In this case, the culprit was “fte”:
[nomerge ] app-editors/fte-20050108-r3 -X +gpm +slang [ebuild N ] virtual/x11-6.8 0 kB [ebuild N ] x11-base/xorg-x11-6.8.2-r6 -3dfx -3dnow (etc.) [ebuild U ] x11-apps/ttmkfdir-3.0.9-r3 [3.0.9-r2] 19 kB
What time is it? The US Naval Observatory Master Clock Time page also shows the seconds, unlike most other world time web pages:
Neat idea. I often remember things visually only. Funny detail: The proof that numlock.ch suffers from maintenance downtimes too, from time to time ;)
Since version 0.95, grub supports booting a cascade of fallback kernels if the default kernel doesn’t boot correctly:
Gentoo Wiki: HOWTO Remote Kernel Upgrade
Grub manual: 4.3.2 Booting fallback systems
I hope it will work when needed..
Happy New Year to all of you! As my public pledge for 2006 I hope for more diversity in thinking and doings again (which requires a deeper understanding of differences).
