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:

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).
Fine. After years (heck, even decades!) of staring into distorting, flickering, radiating and mirrorlike CRT screens we finally managed to banish those darn things from our desks and to use distortion-free, flicker-free, radiation-free, coated TFT screens instead. Time to put glares and reflections back into the GUI (just try to read the labels on the taskbar)! Hallelujah! ;)
(I bet Microsoft will get back to this once the dust has settled. Apple made a similar experience with Aqua’s transparency effect which was significantly reduced in later versions.)
I’ve now enabled a basic captcha system provided by a Movabletype plugin called SCode. In order to make it work I had to do a couple of things that are not mentioned in the official installation instructions:
1. make the mt-scode.cgi CGI script executable:
# chmod a+x mt-scode.cgi
2. make sure that SCode is enabled and configured both on a MT global level and on a per-weblog basis
3. Correct a bug in SCode.pl:
replace security code you see here\” src=\”$path/plugins/SCode/mt-scode.cgi by security code you see here\” src=\”$path”.”plugins/SCode/mt-scode.cgi
#3 is not essential, but a bug nonetheless.
Hopefully, the comment spam problem is now solved for a while by enabling this plugin. Trackback spamming is still possible, though.
Please contact me if you are visually impaired and would like to post a comment on this blog. Ideally, the captcha image should also be available as a sound file/stream, but I haven’t found the time yet to implement sth like this.
Nice to know:

Putty has such a “keep alive” option too (in the “Connection” category). Had to set it to 100 seconds as the according proxy is very restrictive indeed.
