NGINX tuning for best performance

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Get VI bindings in IEX (Elixir REPL)
# VI bindings in iex:
brew install rlwrap # on OSX
echo "alias iex='rlwrap -a foo iex'" >> ~/.bash_profile
echo "set editing-mode vi" >> ~/.inputrc

Откат ошибочной команды git push --force

Откат ошибочной команды git push --force

Иногда при работе с несколькими удалёнными репозиториями в git, может произойти страшное: git push --force в не тот remote и/или не в ту ветку.

Такое может случиться, например, если вы используете [Deis], в котором деплой запускается при git push нужного коммита в сборщик, когда при отладке деплоя после очередного git commit --amend по запарке вместо git push deis master --force делается просто git push --force. Упс.

Как результат, последние коммиты коллег безвозвратно потеряны, и вы чувствуете неотвратимость их ярости…

Но это git, а значит всё можно починить!
