Алфавит по версии версии google suggest:

а=анекдоты
б=билайн
в= в контакте
г=гороскоп
д=дом 2
е=евросеть
ё=ёж
ж=жди меня
з=зайцев нет
и=игры
й=йога
к=контакт
л=любовные смс
м=музыка
н=новости

ч=чат
ь=ьнызфсу(myspace)
ш=шкода
щ=щитовидная железа
ъ=ъж
э=эльдорадо

Интересно то, что алфавит для .ru и для .com немного отличаются.

JRuby improves performance with minor versions!

sv — Sun, 22 Jun 2008 22:10:00 +0200

I’ve done some simple benchmarking with typo bloging engine and here is some graphs on this.
Benchmark was done on jruby and mri with untuned versions of ruby and openjdk 6.0 for jruby.

It’s really awesome improvements! But we have a lot more room for further improvements!

GSoC - Week 3

NoKarma — Sun, 15 Jun 2008 20:33:00 +0200

Week #3 of Google’s Summer of Code is now over, so what have I been working on?

Rubyspec compatibility with 1.8.7 and newer 1.8.6 patchlevel versions

Due to internal changes to the way newer Ruby versions checked for the existance of magic methods like #to_str and #to_int, many of the already existing specs started failing (roughly more than 100 failures). After I started a discussion about this on the #rubyspec channel, Vladimir Sizikov raised his objections on this change on the Ruby-Core mailing list, where there are talks going on about potentially reverting this behaviour.

Finished work on StringIO specs

After many new specs for StringIO and changes to existing StringIO specs, I think StringIO specs have reached a very high level of coverage and quality. This helped the JRuby guys to enormously improve the compatibility between the JRuby version of StringIO and the version that ships with MatzRuby. The specs also point out many differences and bugs in the StringIO implementation currently used in Rubinius.

Also, the specs helped to find some smaller inconsistencies between StringIO and IO behaviour, which have been fixed in the Ruby SVN:

Finished work on smaller libraries

Additionally, I have finished my work on the tmpdir and OpenStruct libraries.

Next Week

Next week, I’ll try to finish specs for the Tempfile library and pick up work on some of the Net libraries.

GSoC - Week 2

NoKarma — Mon, 09 Jun 2008 14:18:00 +0200

And the second week of Google’s Summer of Code comes to an end.

Over the course of the last week, I’ve been working on Net::FTP specs (really, that’s no fun!) and on specs for the Set library.

Thanks to the new specs I’ve added for Set and SortedSet, some bugs have been exposed, for which I’ve submitted bugs to Ruby’s shiny new bugtracker, based on RedMine:

Also, the newest Ruby 1.8.6 version, 1.8.6-pl166, has some bugs, that got exposed by the rubyspecs :D

Module#remove_method broken in 1.8.6-p166

I also started fixing the rubyspecs to comply to Ruby 1.8.7, the “new” stable version of Ruby. It caused over 100 (!) spec failures, as it fixed a lot of bugs and changed behaviour in many places. There have also been backports from the Ruby 1.9 branch, (sadly) causing confusion throughout the whole Ruby Community.

Over the course of the next week, I’m planning to complete specs for Ruby’s StringIO library.

Cygwin git-svn doesn't work

sv — Sat, 07 Jun 2008 21:02:00 +0200

All JRuby maintainers use git-svn for managing their versioning. But jruby on github supported manually.
I’ve also try to use git-svn on my Windows machine and encounter an error:
fatal error - unable to remap cygdb-4.2.dll to same address as parentAfter some googling I’ve found similar problem for python on cygwin(git-svn uses perl).
Again 2-step solution:

Exit all Cygwin processes and stop all Cygwin services.Execute ash from Start/Run… or a cmd or command window. In my case that was ssh,init, svn services and cygwin terminal.
/bin/rebaseall
