Мой форк перевода OSQA: у меня на Github.
Before you begin OSQA installation, you first need to get the source code from subversion. You can receive instruction on how to do this from our Download OSQA page . This guide covers the installation of OSQA on the Ubuntu operating system using a MySQL database. If you’ve achieved a successful installation on Windows, Mac, or any other OS, we are interested in adding your installation methods to our upcoming guides for those systems. To successfully install OSQA, simply perform the instructions in each section as you scroll down the page. Continue reading
OSQA is an opensource Q/A engine. In this article I’ll describe the way I installed it on my VPS.
I like Debian/Ubuntu OS. Debian lacks new packages, that’s why I chose Ubuntu 12.04 LTS.
I had Lighttpd installed on my machine, so firstly I tried to install OSQA on Lighttpd. Googling around I found that running OSQA in fcgi mode is not OK (when you have a VPS). WSGI is the right way. Unfortunately, Lighttpd’s WSGI is very unstable, experimental and unsupported. That’s why I decided to move to nginx.
Django projects are great with pure WSGI servers. So I decided to install nginx with WSGI server (uWSGI, GUnicorn, etc.). Spending 3 days, writing LOTS of site blocks, tuning nginx, messing around with various WSGI servers, I finally switched to Apache.
My Apache/Ubuntu way was as described in article on meta.osqa.com. After doing the steps I received 500 errors as well as this:
Middleware module "django.middleware.csrf" does not define a "CsrfResponseMiddleware" class
OSQA is not compatible with Django 1.4.0, but works OK in 1.3.1. Check your version:
python >>> import django >>> django.VERSION
If necessary install 1.3.1:
sudo easy_install django==1.3.1
In my spare time I’ll continue playing with nginx + uWSGI (or gunicorn), I think it’s the best way of running OSQA.
Bulk email sending with bash:
for email in mail1@example.com mail2@example.com mail3@example.com; do echo -e 'Some text\nWith new lines' | mail -s "MySubject" $email; done
With this bash script one can encode videos for his Android with 480×320 screen.
for f in *.avi;
do ffmpeg -i "$f" -s 480x320 -vcodec mpeg4 -acodec libvo_aacenc \
-ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 `basename $f.mp4`;
done
Enjoy the videos on your commute! 🙂
При установке MeeGo от LinuxCenter Yota работает сразу же. Но что делать тем, кто ставил оригинальную ОС с сайта MeeGo? Скачав MeeGo 1.2 для Cedar Trail с официального сайта, я принялся за настройку моего брелка Yota SWC-U200.
Для работы Yota под Linux необходимо установить пакет madwimax, которого нет в репах по умолчанию. Madwimax имеет зависимость dhclient, которого тоже нет в репах.
Сначала подключил репы Linuxcenter (спасибо Якову Мироничеву за полезный пост). Репы 1.1 катят для 1.2:
sudo zypper addrepo http://meego.linuxcenter.ru/MeeGo/releases/1.1/core/repos/ia32/packages/ "linuxcenter"
Затем их обновил:
sudo zypper refresh
Поставил dhclient:
sudo zypper install dhclient
Качнул madwimax у Mezon и запустил:
cd ~/Downloads wget http://meego.linuxcenter.ru/Mezon/builds/trunk/daily/core/repos/ia32/packages/i586/madwimax-0.1.1-2.mezon.1.0.i586.rpm sudo rpm -i madwimax-0.1.1-2.mezon.1.0.i586.rpm sudo madwimax
Проверил, в ifconfig появился новый интерфейс, а MeeGo сообщил, что я успешно подсоединился к Wired Network. Проверил IP (2ip.ru), действительно, Yota 🙂
На всякий случай кидаю сюда RPM:
dhclient-4.0.1p1-6.10.i586.rpm
madwimax-0.1.1-2.mezon.1.0.i586.rpm
1. Для установки Windows 7 с флешки нужно изначально отформатировать её в NTFS. Флешки, отформатированные в FAT32 не подойдут.
2. Скачать Unetbootin версии 494 (или 490). В последних версиях Unetbootin убрали галочку “показать все устройства”. Без неё вам Unetbootin не покажет устройства с NTFS. Также для Linux необходимо добавить права на выполнение (в Windows нужно просто распаковать архив):
chmod 755 unetbootin-linux-494 ./unetbootin-linux-494
3. Указать путь к образу ISO
4. Дождаться (минут 15) пока система скопирует на флешку файлы и сделает её загрузочной
5. Вставить флешку в нужный компьютер, загрузиться с неё.

Bash script:
#!/bin/bash
#sudo apt-get install imagemagick
for i in {0..31};
do convert -rotate 180 -crop '3262x2330+192+72' img-$i.jpg jpg:- | \
convert -crop '50x100%' jpg:- imgout-$i%d.jpg; \
rm img-$i.jpg; \
done
Code:
find . -name '*.AVI' -exec ffmpeg -i {} -b 1600k {}.mpeg \;
Using ffmpeg to encode video for my Android phone:
find . -iname "*" -exec ffmpeg -i {} -s 480x320 -vcodec mpeg4 \
-acodec aac -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 \
-strict experimental {}.mp4 \;
Explanation:
find command searches for all files with AVI extention and for each of them executes command after —exec switch (which is ffmpeg -i input file -b bit rate). Curly brackets stand for currently found file.
This article explains how to connect to a ssh server located on the internet from a local network protected by a firewall through a HTTPS proxy.
Requirement are :
The ssh daemon need to listen on 443 port. To accomplish this, just edit this file (on debian system) /etc/ssh/sshd_config and add this line :
Port 443
Then restart the daemon :
sudo /etc/init.d/ssh restart
I suppose you are on a Linux system (debian for example). First you have to compile the connect binary which will help your ssh client to use proxies (HTTPS in our case). Then you have to configure your ssh client to tell him to use HTTPS proxy when he tries to connect to your ssh server.
connect software :connect-proxypackage :
sudo apt-get install connect-proxy
cd /tmp/ wget http://www.meadowy.org/~gotoh/ssh/connect.c gcc connect.c -o connect sudo cp connect /usr/local/bin/ ; chmod +x /usr/local/bin/connect
~/.ssh/configfile and add these lines :
## Outside of the firewall, with HTTPS proxy Host my-ssh-server-host.net ProxyCommand connect -H proxy.free.fr:3128 %h 443 ## Inside the firewall (do not use proxy) Host * ProxyCommand connect %h %p
ssh my-ssh-server-host.net
For example to connect to in ssh github.com :
Host github.com ProxyCommand=ssh my-ssh-server-host.net "/bin/nc -w1 %h %p"
