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.

Elixir installation guide

Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.

Como criar uma gem ruby?

Como criar uma gem ruby?

Escolhi tratar sobre esse assunto hoje simplesmente porque foi uma das primeiras coisas que me perguntei "como eu faço isso?" no mundo ruby. Acredito que muita gente se pergunte a mesma coisa e espero que eu possa ajudar em algo para elas. 😀

O que é uma gem?

Bem, se você é um programador java, você chama sua gem de jar, se você é um programador C#, você chama de dll. Resumindo, é uma lib, uma biblioteca contendo códigos que você pode reaproveitar importando em outros projetos.

E usar gems no ruby é muito fácil, se você já deu uma brincada com rails por exemplo, é só você adicionar o código gem 'nome_da_gem' no arquivo Gemfile que está no root, depois executar o comando bundle install para baixar sua gem do repositório e pronto, só sair usando a biblioteca!
