CPython の Core Developer になりました - methaneのブログ
Python 3.6 に取り込まれた dict の新実装などでコアコミッターに興味を持ってもらい、 Core Developer (要するにコミッター) に推薦しようか？という提案をもらいました。 最初はコミッターとか面倒そうだし、コミットメッセージとかNEWSエントリー（通常パッチをコミットするときにコミッターが書く）とかを英語で書くのも英語が得意な人がやったほうがいいだろうし、とりあえず github に移行するまでは様子見しておこうと思ってたのですが、 dict 関係のパッチがいくつもレビュー待ちでなかなかコミットされないのを見て「やっぱりアクティブなコミッターが全然足りてない」と考え直し、志願することに。 で、先月末にコミット権をもらった（というか push できる権限を持った hg アカウントに ssh 鍵を登録してもらった）のですが、新米コミッターは簡単なパッチでも他のコアコミ
Why Uber Engineering Switched from Postgres to MySQL
We’ve represented the old version in red and the new row version in green. Under the hood, Postgres uses another field holding the row version to determine which tuple is most recent. This added field lets the database determine which row tuple to serve to a transaction that may not be allowed to see the latest row version. With Postgres, the primary index and secondary indexes all point directly
Announcing GenStage
Today we are glad to announce the official release of GenStage. GenStage is a new Elixir behaviour for exchanging events with back-pressure between Elixir processes. In the short-term, we expect GenStage to replace the use cases for GenEvent as well as providing a composable abstraction for consuming data from third-party systems. In this blog post we will cover the background that led us to GenSt
Difference between protocol & behaviour in elixir
Behaviours define callbacks & protocols define methods without signatures. Modules implementing a protocol should give definition for all those methods. Same for modules using a behaviour. What is the semantic difference? One difference I can think of is, a protocol can be implemented for a single type only once where as we can implement a behaviour for a module multiple times based on our require

Phoenix 1.0から1.1へのアップデートガイド - Qiita
本日（12/17）、Phoenix 1.1が正式にリリースされましたので早速使ってみた。 1.1にはgettextを使った国際化対応のサポートや、channelのパフォーマンス改善、Instrumentation hooksの追加などがあるそうな。 前提 既に1.0で動いているPhoenixアプリケーションを1.1にアップデートすることが前提。 注意点 基本的にmix.exsへの変更が中心だが、1.1での後方互換の無い変更として、以下がアナウンスされているため、そこだけコードをいじる。 Backward incompatible changes [View] The @inner assign has been removed in favor of explicit rendering with render/3and the new @view_module and view_temp
Top 10 Python libraries of 2015
Everyone and their grandma seems to be writing top 10 lists, so we couldn't be less and compiled our own. Here is a list of the best 10 Python libraries you should know about that we have used in 2015, in no particular order. We try to avoid most established choices such as Django, Flask, Django Rest Framework, etc. and go for libraries that might not be as well known. Fasten your seatbelt, here w
