Welcome! This guide will teach you about Elixir fundamentals - the language syntax, how to define modules, the common data structures in the language, and more. This chapter will focus on ensuring that Elixir is installed and that you can successfully run Elixir's Interactive Shell, called IEx. Let's get started. InstallationIf you haven't yet installed Elixir, visit our installation page. Once yo

Hey yo! This is Learn You a Haskell, the funkiest way to learn Haskell, which is the best functional programming language around. You may have heard of it. This guide is meant for people who have programmed already, but have yet to try functional programming. The whole thing is completely free to read online, but it's also available in print and I encourage you to buy as many copies as you can aff
ご存知かとは思いますが、これまで仕事場では皆様のツイートと呼ばれる140文字程度の投稿を読んで適切なタイムラインに仕分けしたり、ハッシュタグを見て検索結果に追加したりとなかなか骨が折れる作業をしていて、随分慣れてきたのですが、どうしても最近はじまった「60秒でツイートを届けるキャンペーン」で間に合わないことが多く、中にはUnicodeの合字を組み合わせた塩抜きポテトみたいなツイートも多く、一部、Ruby を使って自動化したりしてみたのですが、そろそろ体力の限界を感じていたところでした1。 そんな折、同僚が、「オレ、Scala を使ってるんだけど肩こりも治ったし、60秒キャンペーンも余裕だよー」って言ってるのを聞いて、そんなにいいなら、とちょっと使ってみることにしました。 新しい言語を覚える 実際のところ、仕事場ではかなり前から Scala で書かれたプロジェクトがありましたが、この公開され
Clojure is a dynamic development environment where you interact with your program while you write it, growing and adding to it while it’s running. To work with Clojure you need an editor that supports evaluation in source files and structural editing (working with nested forms in addition to character editing). Clojure provides the language, a REPL (Read Eval Print Loop), library support, and prog
Emacs エディターで C 言語のプログラムを書く人向けに、入門用の解説がないように思う。そこで、知っておくと便利な機能をまとめてみた。 読者は、Emacs の操作とカスタマイズが最低限できる人を対象にしている。つまり、C-x C-f といったショートカット・キーが使えて、.emacs の設定ファイルがいじれる人。各機能について、基本的な使い方とその効果、あと最低限の設定について書き出した。 目次 ソースの色付け インデント アラインメント コメント info マニュアル スペル・チェック タグ・ジャンプ 関数名の補完入力 コンパイルとエラー行ジャンプ ChangeLog ファイル 1. ソースの色付け Emacs は、C 言語のソース・ファイルを解析して、if や for といったキーワードに対して、自動で色を付ける。 色を付けることでソースにメリハリが生まれ、可読性が上がる。また、ス

Last updated November 18, 2025 Ruby on Rails is a popular web framework written in Ruby. This guide covers using Rails 8 on Heroku. For information on running previous versions of Rails on Heroku, see the tutorial for Rails 7.x or Rails 6.x. The tutorial assumes that you have: Basic familiarity with Ruby, Ruby on Rails, and Git A locally installed version of Ruby 3.2.0+, Rubygems, Bundler, and Rai
Grunt and Grunt plugins are installed and managed via npm, the Node.js package manager. Grunt 0.4.x requires stable Node.js versions >= 0.8.0. Before setting up Grunt ensure that your npm is up-to-date by running npm update -g npm (this might require sudo on certain systems). If you already have installed Grunt and are now searching for some quick reference, please checkout our Gruntfile example a
At the heart of GitHub is an open-source version control system (VCS) called Git. Git is responsible for everything GitHub-related that happens locally on your computer. Using Git To use Git on the command line, you will need to download, install, and configure Git on your computer. You can also install GitHub CLI to use GitHub from the command line. For more information, see About GitHub CLI. If
So What's Meteor? Meteor is at the forefront of a new wave of frameworks that make building web apps easier, simpler, and faster. Not only is Meteor entirely real-time (meaning any change to your database is automatically reflected live in the browser), but the fact that it uses JavaScript on both the client and server means that you won't have to juggle with multiple languages and environments an
