<h2 id="gnupg_sign_verify">GnuPG Insta-Party Signature List Verification Script</h2>
Some key-signing parties are conducted in a way that the
a file containing the fingerprints is distributed to everybody, and is then
verified to be correct by its SHA1 hash. Then, the keyring is made available
to the public. Now the question is whether the signatures in the keyring are
the same as those in the file.
To resolve it, I wrote <a href="<bit_link "gpg-verify.pl" />">a script</a>
that checks the signatures in the file and verifies that they are the same
as those reported by GPG in the key-ring. You can freely use it under
the terms of the MIT X11 license.
Using it I signed the keys, by first running it, and then using kgpg (part
of kdeutils) to sign all the keys at once. Truly an improvement over the
time, where I signed each key individually, using my password like a zillion

<h2 id="xchat_xmms_nowplay"><a href="<bit_link "nowplay-xchat.pl" />">X-Chat /nowplay command using XMMS</a></h2>
What this little Perl script does is register an
<a href="http://www.xchat.org/">X-Chat</a> command called <tt>/nowplay</tt>,
that whenever invoked displays a message of “/me is listening to My Artist -
My Song” in the current channel. Feel free to make any use of it whatsoever
under the terms of the MIT X11 license. It queries either
<a href="http://amarok.kde.org/">Amarok</a> or <a href="http://www.xmms.org/">XMMS 1.x</a>.
You need to install the
<a href="http://search.cpan.org/dist/Xmms-Perl/">Xmms-Perl distribution</a>
and have the X-Chat Perl interface. To use, make it executable and put it
under your <tt>$HOME/.xchat2</tt> directory.

The format used for the distribution lists has changed from earlier versions

<h2 id="amarok">Amarok Scripts</h2>
<a href="http://amarok.kde.org/">Amarok</a> is a powerful and easy to use

allow one to customise the player using practically any language.
Here are links to the Amarok scripts I wrote:
Volume Script for Amarok 1.x</a>,
Volume Script for Amarok 2.x</a> - This script maintains a per-song volume
information. What it means is that a volume is associated with each song,
which is recorded whenever the volume changes, and is restored to its last
value when the song is played again. This is useful if you have several songs
which sound louder or softer than the rest.

<h2 id="fluttering_flag"><a href="<bit_link "sdl-flag-0.2.0.c" />">SDL
This is a fluttering flag, not quite unlike the one presented at the
beginning of <a href="http://en.wikipedia.org/wiki/Unreal_(demo)">the
Future Crew’s Unreal Demo</a>, but still not as polished. It’s one
self-contained ANSI C file, that requires <a href="http://www.libsdl.org/">the
SDL (Simple DirectMedia Layer) Library</a>.
See <a href="$(ROOT)/prog-evolution/pre-elpas.html">this page</a> for the
story of how I originally recreated the fluttering flag effect.

reduced and evolved. It supplies use of the left and right arrow keys for
moving between slides (<tt><li></tt> elements

provides the “n” and “p” keys to follow the links with the appropriate
If the global variable <tt>rtl_keys</tt> is set to true, then the left and
right keys are reversed to be suitable for a language that is written
from right to left.
