É difícil falar de Ruby sem mencionar seu framework web mais famoso, Ruby on Rails. Mas não adianta muito encarar o framework sem um prévio estudo da linguagem (o que de fato já observei acontecer inúmeras vezes). Esse post tem como intuito auxiliar na aprendizagem tanto da linguagem como do framework, para evitar que erros comuns como esse tornem a utilização de ambos um desastre.

Ruby

Ruby é uma linguagem de programação que apareceu para o mundo em 1995, criada por Yukihiro "Matz" Matsumoto. Tem como características o fato de ser uma linguagem de uso geral, com tipagem dinâmica e forte, orientada a objetos e que incorpora diversos paradigmas de programação, como o funcional e o imperativo.

• Install Arduino IDE to /opt/arduino
• Install PubSubClient and MsgFlo
• Edit /opt/arduino/libraries/PubSubClient/src/PubSubClient.h and set a bigger buffer size (for example 512)
• Add ESP8266 board URL:

/opt/arduino/arduino --pref "boardsmanager.additional.urls=http://arduino.esp8266.com/stable/package_esp8266com_index.json" --save-prefs

• Install board package

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

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.
