ld.so, ld.so.cache and ld.so.conf
When you modify /etc/ld.so.conf, it won't have any effect until you regenerate /etc/ld.so.cache with ldconfig! Manpage for ld.so misleadingly mentions ld.so.conf while it doesn't affect dynamic loader's behaviour in any way.
In practice this is important when you create a chroot environment. Copying host's ld.so.cache into chroot would be wrong ( Read more... ) -
accessing .onion sites HOWTO
If you use "torbrowser" for browsing, .onion sites should be working out-of-the-box. In ordinary browser, .onion sites are usually inaccessible because such names can't be resolved via DNS to IP addresses even if you use "tor" daemon as your DNS resolver:
xrgtn@m2n32bk:~$ nslookup protonirockerxow.onion
Server: 127.0.0.1

asyncts buffer drop
Если при перекодировании видео ffmpeg-ом он выдаёт сообщения типа "[Parsed_asyncts_2 @ 0x956a40] Non-monotonous timestamps, dropping whole buffer.", это означает, что разброс (jitter) временных меток в аудиопотоке входного файла превышает размер буфера asyncts (по умолчанию 0.1сек.). В таких случаях нужно подобрать больший min_delay вручную -- ( Read more... ) -
split-cue
Во время новогодних праздников я написал утилиту для нарезания audio CD образов (.clone, .ape, .flac или .wav с парным .cue или .toc индексом) на отдельные аудио дорожки в формате .mp3, .ogg, .wav или .flac со всеми причитающимися тэгами (year, album, genre, tracknumber, artist, title, albumartist). Например, на входе имеем six-string_samurai.clone ( Read more... ) -
transparent tor proxying HOWTO
Прозрачное проксирование tor-а необходимо, когда нужно перенаправить через tor не только браузерный траффик, но и траффик плагинов и приложений: к примеру, flash, torrent, email, jabber, icq и т.д. Теоретически можно обойтись непрозрачным, т.е. явным проксированием, копаясь в настройках каждого приложения и плагина по отдельности, однако прозрачное ( Read more... ) -

linux on sony vaio vgn-ux230p
First of all, thanks to Constantinos Pitris for his great Ubuntu on UX50 guide!
There are several problems though with UX230P and Debian squeeze (linux kernel 2.6.32-5-868, but I'm sure ALPS stickpointer problems are same in all kernels from 2.6.32 up to 2.6.39 because the code in alps.c is the same):- ALPS stickpointer is too sensitive and keeps ( Read more... )
