подскажите про IR

2009-11-17T23:45:35Z

наткнулся на такую вот штучку: http://www.dealextreme.com/details.dx/sku.12902
стало интересно - где взять подключаемый по usb(rs232) управляющий элемент ? управляемых руками - хоть одним местом есть можно, а вот что б через комп управлять - не нашел :-(

идея состоит в следующем - периодически в руки попадают девайсы, которые легко завесить наглухо. в таких случаях помогает ресет или включение-выключение питания. хотелось бы воткнуть девайс в управляемую розетку, а управляющий элемент подключить к рядом стоящему системнику, что можно было удаленно перезагружать устройство ;-)

понравилась фраза

в C с этим проще - код делает то, что написано

kde4. попытка N не помню

сабж.
второй день.
на этот раз глюков значительно меньше.
и на этот раз желания вернуться на kde3 не возникает.

раздражает отсутствие поддержки flash в konqueror и отсутствие нормальных плагинов - особенно переключение между несколькими проксями на лету.

PS начал посматривать на более другие браузеры. что-то файрфокс стал напрягать.

я поражен степенью сжатия 7z

arm дистрибутивы

2009-11-05T20:09:00Z

а какие есть ?

уже грузятся:
1. ubuntu
2. ALT

на очереди:
1. Gentoo
2. Debian
3. Fedora
4. FreeBSD

Больше не знаю. Разве что специализированные, но это неинтересно.

PS очень жалко, что девайсы у нас тяжело достать - было бы интересно на лабах дать возможность студентам побаловаться в свободном режиме, а то они кроме x86 ничего и не трогают толком. Ядрышко только придется без поддержки mtd пересобирать ;-)

хочется :-(

а вот подскажите

2009-11-04T13:56:25Z

задумался и сам не знаю, что использовать.

Дано:
- сервер Linux за NAT, на который можно пробросить любые порты
- клиент Windows за NAT - может использовать несколько разрешенных портов.
Задача:
расшарить на сервере часть файловой системы по паролю в режиме r/w

как-бы linux-linux - проблем нет: ssh/scp+fuse/mc/fish - и даже неподготовленный пользователь сможет заливать/качать файлы.

а вот что использвать из-под винды ? да еще так, что б не из консоли ;-) не знаю просто. посоветуйте.

ftp - отпадает из-за обоюдных натов
smb/cifs - не знаю, умеет ли венда работать по нестандартным портам, потому как стандартные прибиваются провайдерами

WebDAV ? что еще ?

UPD: решено.
ftp - можно. winSCP - встраивается куда нужно.

PS спасибо за советы

Закон vs СПО

2009-10-10T16:45:24Z

Тут ребе kong_en_ge слил, якобы достоверную инфу про запрет свободного ПО в РБ для юрлиц.

Мое мнение, что такого не может быть ~~потому что такого не может быть~~, т.к. СПО (а заодно куча проприетарщины ;-)) является общественным достоянием, согласно закону РБ «Об авторском праве и смежных правах»

определение: "общественное достояние — объекты авторского права и смежных прав, имущественные права на которые истекли или отсутствовали;"

<cut>

Проверьте меня: это фактически все ПО с открытым исходным кодом у нас распространяется под локальным аналогом BSD ? А с учетом, что GPL не действует - можно "продавать бесплатные линуксы" (с) без предоставления исходного кода ? ;-)

UPD: ребе kong_en_ge поправил, так что перевести в общественное достояние не получится, скорее всего :-/

Попытка номер 2:
"запрещено дарение в отношениях между коммерческими организациями" - ну и отлично!
debian - некоммерческая организация, CERN (CentOS) - тоже, как и много других. соответственно не попадает под эту норму установка скачанного из сети дистрибутива, который был произведен некоммерческой организацией.
Проблема будет с RedHat, SuSE, ALT (с этим и я решить помогу ;-)), Ubuntu и т.д.

Отдельные пакеты - вообще произведения частных лиц.

48. Safe Exam Browser

This app locks down students' PCs so that they can't use any unauthorized materials while taking an online exam. By default, it prevents students from closing or leaving the testing window, using keyboard shortcuts, using the right-click menus, switching to other applications, or surfing the Internet. Operating System: Windows.

Typing

49. TuxType

In addition to typing lessons, TuxType includes two games for practicing your keyboarding skills. In Fish Cascade, kids help Tux the Linux penguin eat fish by typing the correct letters, and in Comet Zap, they save Tux from destruction by typing the correct letters. With its simple nature and cartoon character, this app is best for elementary-school kids who are just learning their way around the keyboard. Operating System: Windows, Linux, OS X.

50. Klavaro

In addition to the standard "qwerty" keyboard, Klavaro supports five other international keyboards and even lets you custom design your own keyboard.

я уж молчу про рекурсивные вызовы rpm и удаление фалов, принадлежащих пакету, во время инсталляции :-E

2009-08-28T21:25:36Z

постоянно забываю, как в шелловских скриптах сделать вывод stdout и stderr на экран, а потом еще отдельно обработать один из потоков. вот одно из решений:

exec 3>&1
{
# здесь должны быть команды
} 2>&1 >&3 3>&- | tee -a errorlog

# или так для логгинга только stdout
#} 2>&3 3>&- | tee -a goodlog
