C# と F# の Async: C# の非同期の落とし穴

2月に、私は毎年恒例のMVPサミット ── Microsoft が MVP のために主催するイベント ── に出席しました。私はボストンとニューヨークを訪問する機会を利用して、二つの F# に関する講演と Channel9 lecture about type providers の収録を行いました。他のすべての活動（しばしばパブで他の F#er を議論に巻き込んだり、朝まで長い睡眠）にもかかわらず、私はいくつかの講演に参加し果せました。

R'0'RSを読む

これは`Lisp Advent Calendar 2013`_の19日目の文章です。

はじめに

表題に出てくるR'0'RSは正式な名称ではありません。表題で私がR'0'RSと呼んでいる文章はSchemeの言語仕様を記述した報告書、いわゆるRnRSの元祖といえる"Scheme: An Interpreter for Extended Lambda Calculus"です。この文章はAI Memo 349としても知られています。以下ではAIM 349と呼びます。

Reader Macros in Common Lisp

This post also appears on lisper.in.

Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.

Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):

The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. ...read-macros... do their work at read-time.

Scala の省略ルール早覚え

このルールさえ押さえておけば、読んでいるコードが省略記法を使っていてもほぼ読めるようになります。

メソッド定義

def concatAsString(a: Int, b: Int): String = {
  val a_ = a.toString();
  val b_ = b.toString();
