When 2017/04/01 At Elixir Conf Japan 2017 LT Self Introduction ちきさん (Tomohiro Noguchi) Twitter/GitHub/Qiita: @ovrmrw I've started to learn Elixir 1 month ago. What I talk about Reading a JSON file and doing MapReduce. (JSONファイルを読み込んでMapReduceしたい。) Differences between Eager, Lazy and Flow(Concurrent). (Eager, Lazy, Flow(Concurrent)の違いについて。) Flow & GenStage is extremely fast. (Flowめちゃくちゃ速い。) === Git
[翻訳] ElixirとErlangの変数を比較する - Qiita
José Valimさん1の2016年1月12日付のブログ記事"Comparing Elixir and Erlang variables"の翻訳です。 時々Erlangのプログラマは「Elixirの変数は隠れたバグの温床になるのでは」と心配するようです。この記事ではそういう心配についてと、Erlangでの変数も「隠れたバグ」を生み出しかねず、一方でElixirはそれらのうちのいくつかを除去するということについて議論します。 話を始める前に短い放棄声明を…: Elixirは可変(mutable)な変数を持っていません。あるのは再バインドです。可変性はよくストレージと関連付けられます。Elixirでは保存された値を変更することはできません(Erlangと同じです)。可変な変数の例としてF#を見てみましょう。F#では明示的にmutableキーワード(例えばlet mutable x = 5)に

Benchmarking a Go AI in Ruby: CRuby vs. Rubinius vs. JRuby vs. Truffle – a year later
Thoughts on different Ruby implementations Let’s wrap this up with a couple of thoughts on the different implementations: TruffleRuby TruffleRuby is making steady and great progress, which I’m thoroughly impressed with. To be honest, I was wondering if its performance increased since the last benchmark as I was worried that implementing new Ruby features would lead to decreased performance. Seeing

Clojure vs Ruby, Part I
2008-12-13 I’m a performance guy, I’ll admit it. I love performance tuning and comparing code to see why one thing is slower than another. I’ve recently taken a shine to the Clojure programming language as it seems to combine two good things: an incredibly fast and reliable VM and a functional language designed for concurrency. Here’s my first performance test: the ever-reliable fibonacci method.
Erlang/Elixir Syntax: A Crash Course
Erlang/Elixir Syntax: A Crash Course This is a quick introduction to the Elixir syntax for Erlang developers and vice-versa. It is the absolute minimum amount of knowledge you need in order to understand Elixir/Erlang code, support interoperability, read the docs, sample code, etc. Running code Erlang The fastest way to run some code is to launch the Erlang shell – erl.
