A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

Tinder API documentation

Note: this was written in April/May 2014 and the API may has definitely changed since. I have nothing to do with Tinder, nor its API, and I do not offer any support for anything you may build on top of this. Proceed with caution

http://rsty.org/

I've sniffed most of the Tinder API to see how it works. You can use this to create bots (etc) very trivially. Some example python bot code is here -> https://gist.github.com/rtt/5a2e0cfa638c938cca59 (horribly quick and dirty, you've been warned!)

Redis Cluster のリシャーディングとorphaned masterの話

（2019/04 追記 こちらの情報は非常に古く、またRC版での結果となります。記録として残していますが参考になさらないでください）

CyberAgent エンジニア Advent Calendar 2014 2日目です。

昨日に引き続き、秋葉原ラボの柿島が担当します。仕事ではHadoopクラスタの運用を中心に、秋葉原ラボのインフラ/ミドルウェアまわりを担当しています。今年はHadoop、mesos、Aerospikeと分散型のシステムを触る機会が多い1年でした。

この記事のテーマはRedis Clusterです。Redis Clusterが使えるようになるRedis 3.0.0は10月にRC1がリリースされました。2015年のQ1にstableリリースを目指しているようです。

マージ済みのリモートブランチを全て削除

git branch -r --merged master | grep -v -e master -e develop | sed -e 's% *origin/%%' | xargs -I% git push --delete origin %

1. remote の master に merge済み の branch をすべて表示して
2. master と develop は消えてほしくないので除外して
3. origin/ を削除して
4. xargs （-I% % で ブランチ名を渡しつつ、全て削除する）
