The purpose of this tutorial is to get you started programming in C3 as soon as possible. Some familiarity with the C language is recommended, but general programming concepts will still be covered.https://codapi.org/try/python/Sat, 08 Mar 2025 00:00:00 +0000https://codapi.org/try/python/Python was created by Guido van Rossum in the early 90s. It is now one of the most popular languages in existence. I fell in love with Python for its syntactic clarity. It's basically executable pseudocode. ✨ This is an open source guide.

Curl runs on 92 operating systems and has over 20 billion installations worldwide. Curl supports a crazy number of protocols, from HTTP, FTP and TELNET to IMAP, LDAP and GOPHER. It runs on 92 operating systems and has over 20 billion installations worldwide.https://codapi.org/try/grep/Fri, 29 Mar 2024 00:00:00 +0000https://codapi.org/try/grep/grep is the ultimate text search tool available on virtually all Linux machines. While there are now better alternatives (such as ripgrep), you will still often find yourself on a server where grep is the only search tool available. So it's nice to have a working knowledge of it.

It's not the latest trend in programming language theory, but it is a way to solve real-world problems. Go draws concepts from imperative languages with static typing. It's fast to compile and fast to execute, it adds easy-to-understand concurrency because multicore CPUs are now common, and it's used successfully in large codebases. Go comes with a rich standard library and a large, thriving community.https://codapi.org/try/ripgrep/Tue, 19 Mar 2024 00:00:00 +0000https://codapi.org/try/ripgrep/ripgrep is a command line tool that searches your files for patterns that you give it. It's similar to grep, but provides a better user experience and is (generally) faster. Basics · Recursive search · Useful options · Replacements · Configuration · Further reading ✨ This is an open source guide. Feel free to improve it! Basics ripgrep behaves as if it were reading each file line by line: If a line matches the pattern given to ripgrep, that line is printed.https://codapi.org/try/git/Thu, 14 Mar 2024 00:00:00 +0000https://codapi.org/try/git/Git is the distributed version control system used in software development today. It's very powerful, but also known for its not-so-obvious syntax. Concepts · Basics · Branch & merge · Local & remote · Undo · Advanced · Final thoughts ✨ This is an open source guide. Feel free to improve it! Concepts This is the only piece of theory in the guide. I'll keep it short and simplified to the π == 3 level.https://codapi.org/try/caddy/Sun, 03 Mar 2024 00:00:00 +0000https://codapi.org/try/caddy/Caddy is a powerful, extensible server platform to serve your sites, services, and apps. Most people use Caddy as a web server or proxy. This interactive guide introduces the basics of Caddy, Caddy API and the Caddyfile.
