日本語JRuby: 3月 2010
http://jruby-ja.blogspot.com/2010_03_01_archive.html
JRubyはRuby言語の実装の中では一際起動が遅い事で悪名高くなってしまいました。一部は、JITの生成品がなくてブートストラップして動き出すまでに時間がかかってしまうJVMを使っているせいです。起動の際のボトルネックが報告されて原因が解明されればそれを除く努力を我々はしていますが、JRuby自体にも問題があります。起動の問題は、実は簡単な設定問題である事もしばしばです。JRubyの起動を早くするコツを幾つか見ていきましょう。 注意。JRuby自体の起動は、他のJVM言語に較べると結構いい線いっていますが、MatzのRuby（一般的には最も速い実装とは言えない）の起動は素晴らしく早いです。 26085;本語JRuby.

日本語JRuby: JRubyのメモリを観察するには
http://jruby-ja.blogspot.com/2010/07/jruby.html
Ruby言語の各実装において、どんなメモリ消費を解析するツールがあるのかが近頃ちょっとした話題になっています。 それもその筈、Rubyで書かれたアプリケーションの（不具合の調査は言うに及ばず）メモリ消費の具合を詳しく調べるのは容易い事ではありません。 JRubyを使わないのなら、そうです。 本稿では実際にこのうちの二つのツールをどの様に使いこなすか見ていく事にします。 取り上げたツールは起動中のJVMを観察するグラフィカルなツールであるVisualVMと、 ヒープをダンプして事後解析を可能にするjmapとjhatのタッグチームです。 ここで紹介するツールはJRubyのどのバージョンでも使う事が出来ますが、JRuby 1.6の開発に当たり、 様々な改良を施してあります。 特記すべきは、RubyでのオブジェクトとJavaに於けるオブジェクトが並んで表示されるようにしてある点です。 ここでもう少し解説しましょう。 Projects/jruby ➔ cat foo heap example.rb. 10000times { ary Foo.new }. Puts "ready for analysis!

今日ツイッターで、「JVM及びJDKが、あらゆるプログラミングにおいて真にイケてるプラットフォームになる為には未だ幾つかの欠陥が有る」と呟きました。沢山の人から「もっと詳しく」とせっつかれたので、ここに短く書き起こしておきます。勿論、これで全部という訳ではないのでしょうが、今日思いついたのはこれだけです。 JVM上でJRubyが動く事の利点は折りに触れて述べてきました。JRubyのパフォーマンス数値はそこそこの結果を出しているのですが、多くの人々の期待に反して「抜群に素晴らしい」というものではありませんでした。詰まる所、他のRuby言語の実装に較べて良い結果を出したとしても、静的な型システムを用いる他のJVM言語には敵わないのでした。 26085;本語JRuby.

Helping Ruby and Java Evolve Together. Thursday, September 23, 2010. This is a repost of an article I wrote in 2004, which I stumbled upon this evening and thought worthy of a reprint. Feel free to rip it up and offer your own commentary. I think it is still 100% valid.). I came up with the most compelling idea for a Disney-style film the other day. (Ok, perhaps not the most compelling idea, but certainly a fair shot at one). So then, you ask, if nature isn't "good", then what is it? Da Vinci Machine Pro...

The first two were on Browsing Memory the JRuby Way. And Finding Leaks in Ruby Apps with Eclipse Memory Analyzer. Hello again, friends! I'm back with more exciting memory analysis tips and tricks! That's what I'm going to show you today. The APIs we'll be using are part of the Java Debug Interface (JDI). Which also includes a C/ API. You can either have t...

Helping Ruby and Java Evolve Together. Thursday, December 23, 2010. Improved JRuby Startup by Deferring Gem Plugins. Another present for you JRubyists out there! JRuby has had notoriously bad startup times. Not as bad as, say, IronRuby (sorry guys! Before, and these mostly apply to vanilla JRuby startup performance. The good news is that it looks like my proposed change – making plugin scanning happen *only* when using the "gem" command. Projects/jruby ➔ git stash pop. Changed but not updated:. I've alre...

Helping Ruby and Java Evolve Together. Wednesday, January 19, 2011. JRuby on Rails on Amazon Elastic Beanstalk. Amazon this week announced Elastic Beanstalk. A managed Apache Tomcat. Service for AWS. Naturally, I had to try JRuby on it. First, the bad:. AWSEB is really slow to deploy stuff. Several times it got "stuck" and I waited for more than 30 minutes for it to recover. It did not appear to be an app issue, since the app came up just fine. There is no step two. Once the instance has been prepared, y...

Helping Ruby and Java Evolve Together. Wednesday, January 05, 2011. Representing Non-Unicode Text on the JVM. JRuby is an implementation of Ruby, and in order to achieve the high level of compatibility we boast we've had to put in some extra work. Probably the biggest area is in management of String data. Strings in Ruby 1.8. There's also another major benefit: we can support Ruby 1.9's "multilingualization". Strings in Ruby 1.9. S excellent post on Ruby 1.9 Encodings: A Primer.

Helping Ruby and Java Evolve Together. Tuesday, January 04, 2011. Flat and Graph Profiles for JRuby 1.6. Sometimes it's the little things that make all the difference in the world. To help improve the situation, we recently got the ruby-debug maintainers to ship our JRuby version, so JRuby has easy-to-use command-line Ruby debugging support. You can simply "gem install ruby-debug" now, so we'll stop shipping it in JRuby 1.6. To continue this trend, we enlisted the help of Dan Lucraft. For the uninitiated...

Posted by Nick Sieger Mon, 22 Nov 2010 18:30:00 GMT. I intended to give this brief as a lightning talk at RubyConf 2010, but unfortunately did not get a chance. Though I kept the message simple, I think if you sympathize with being a perfectionist you can find some part of these points that rings true. I know I still have a ways to go. In heeding my own advice, and not only in software but in my life as a whole. Thanks to Hiro Asari. For the Japanese translations and Jeremy Hinegardner. I hate this word.

JRubyKaigi 2011、RubyKaigi 2011 で喋ってきました。 凱旋（？）. 2011年7月14日、Rubyで飯を食うようになって初めて帰国しました。タイトルにある通り、JRuby会議とRuby会議で喋る為です。東京への出張は2004年に一回ありましたけど、その時は別の会社で、しかもその会社のCEOの通訳みたいな感じで詰まる所「おまけ」だったので、今回は少し箔がついた感じの帰国でした。 余談ですが、今回の帰国便はデトロイト発の羽田行きでした。ボーイング777型機で、私の座った席には電源が付いていて、ラップトップの電池の残量を気にする事なく道中を楽しむ事が出来ました。惜しむらくはWiFiがなかったのでネットで. 調べものが出来なかった事です。乗機率がかなり酷くて、乗っていた人全員が最低三席を占拠して横になって眠れるくらいでした。東京への便が（昨今の事情で）全てそうなのかと思ったのですが、成田への便は結構混んでいたという同僚の話でした。 JRuby 1.6.0 がリリースされました。 ホームページ: http:/ www.jruby.org/. このリリースは、ユーザから報告...
