On October 10th, the two-day RICON 2012 conference kicks off with a focus on distributed systems. Yes, there will be a large focus on Riak. The talk schedule makes that clear. However, the focus on the conference is really about distributed systems and getting smart people to come together and hang out for a couple days. Like many conferences, the most memorable element is going to be the people you meet and the side conversations over coffee and beer.

Hi. My name is Sadayuki "Sada" Furuhashi. I am the author of the MessagePack serialization format as well as its implementation in C/C++/Ruby.
Recently, MessagePack made it to the front page of Hacker News with this blog entry by Olaf, the creator of the Facebook game ZeroPilot. In the comment thread, there were several criticisms for the blog post as well as MessagePack itself, and I thought this was a good opportunity for me to address the questions and share my thoughts.
To the best of my understanding, roughly speaking, the criticisms fell into the following two categories.
Dear MessagePack developers,
This is Sadayuki Furuhashi. This email proposes my plan to update the following resources which are shared by all implementation projects:
- GitHub (http://github.com/msgpack)
- Web site (http://msgpack.org)
- JIRA (http://jira.msgpack.org)
- Hudson (http://ci.msgpack.org)
We made it possible. Next, we'll make it beautiful.
Suffering-oriented programming
- 柔軟性向上
- 予想以上に複雑な使い方をしているケースが多かったので、設定ファイルも複雑化して対応する
#NoSQLデータモデリング技法
原文:NoSQL Data Modeling Techniques « Highly Scalable Blog
I translated this article for study. contact matope[dot]ono[gmail] if any problem.
NoSQLデータベースはスケーラビリティ、パフォーマンス、一貫性といった様々な非機能要件から比較される。NoSQLのこの側面は実践と理論の両面からよく研究されている。ある種の非機能特性はNoSQLを利用する主な動機であり、NoSQLシステムによく適用されるCAP定理がそうであるように分散システムの基本的原則だからだ。一方で、NoSQLデータモデリングはあまり研究されておらず、リレーショナルデータベースに見られるようなシステマティックな理論に欠けている。本稿で、私はデータモデリングの視点からのNoSQLシステムファミリーの短い比較といくつかの共通するモデリングテクニックの要約を解説したい。
本稿をレビューして文法を清書してくれたDaniel Kirkdorfferに感謝したいと思う
