Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

Sete Atitudes para Hackear a Indústria de Software

By Klaus Wuestefeld

1) Torne-se excelente.

Seja realmente bom em alguma coisa. Não fique só choramingando ou querendo progredir às custas dos outros. Não pense q pq vc sentou 4 anos numa faculdade ouvindo um professor falar sobre software q vc sabe alguma coisa. Jogador de futebol não aprende a jogar bola tendo

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

Design rules

General resources

• Fortran Wiki - This is a user maintaned website containing many links to resources on Fortran (generic programming, string handling, interoperability with other languages, object oriented programming, GUI development, compilers, build tools, unit testing, etc.)
• Fortran Wikipedia Page - The Fortran page on Wikipedia is quite resourceful on the history and semantics of the language. A list of language features for Fortran 95 has it's own page.
• User notes on Fortran programming - An old practical guide to the Fortran language (FORTRAN 77 and Fortran 90).
• Fortran Best Practices - A collection of modern canonical ways of doing thins in Fortran.

Welcome

Who is this guy?

Goal(s)

1. Don't WTF quite so much when looking at C++ PRs
2. Know what you don't know (so you know what to look up to learn more)

Agenda

Install Wine with Mono & Gecko in Ubuntu 20.04

Warning: Do not try those command in your main PC, I test in a virtual Machine

Note: Most of commands are from the Dockerfile in Reference section. If you want to test wine, just run their docker container

1. Setup PPA

sudo dpkg --add-architecture i386
wget -qO - https://dl.winehq.org/wine-builds/winehq.key | sudo tee /etc/apt/trusted.gpg.d/winehq.asc
