The 1st day of RubyKaigi 2010 was held (only afternoon) at here.



I attended some sessions and try to report them.

• If the session has a movie in English, I just write summaries of the article. Please see that movies if you want more details.
• If the session has a movie in Japanese, I write the article with translating and little-summarizing.
• If the session has no movies in any languges, I try to write the article with little-summarizing.
• But, for Ceremonies and Lightning Talks, I only put the link of movies.
• And I don't translate Q&As in the article because these are the gift for attendees in there.

Ruby 1.9.2 p0 is FINALLY released

In two days ago, Ruby 1.9.2 p0 has been released. Before installing it, remember the 2nd day of RubyKaigi 2009 (Morning) and this article I mentioned. Ruby team recommends we are installing Ruby 1.9.2 and later with '1.9.1' path. So let's install and check

> ./configure --prefix=/opt/ruby-1.9.1 --enable-shared --srcdir=.
> make
> sudo make install
> /opt/ruby-1.9.1/bin/ruby -v
ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux]
> /opt/ruby-1.9.1/bin/ruby -e 'puts RUBY_VERSION, $:'
1.9.2
/opt/ruby-1.9.1/lib/ruby/site_ruby/1.9.1
/opt/ruby-1.9.1/lib/ruby/site_ruby/1.9.1/i686-linux
/opt/ruby-1.9.1/lib/ruby/site_ruby
/opt/ruby-1.9.1/lib/ruby/vendor_ruby/1.9.1
/opt/ruby-1.9.1/lib/ruby/vendor_ruby/1.9.1/i686-linux
/opt/ruby-1.9.1/lib/ruby/vendor_ruby
/opt/ruby-1.9.1/lib/ruby/1.9.1
/opt/ruby-1.9.1/lib/ruby/1.9.1/i686-linux

As you see, $: does not contain . directory.

How to add official tweet button on each blogspot posts

In yesterday, Official tweet button has been released. But, as out-of-box, this is not optimized for each blog posts like facebook's like button I wrote in phosphorescence: How to add facebook like button on each blogspot post. So I do the "try and error" to customize tweet button for each blogspot post, then I found the approach with referring official tweet button API page.

1. [Layout] -> [Edit HTML]
2. Turn on the checkbox "Expand widget templates"
3. Into the tag of class='post-header-line-n' or class='post-footer-line-n', put the snipet like below:
   

   <a class='twitter-share-button' data-count='horizontal' data-via='your_twitter_name' expr:data-text='data:post.title' expr:data-url='data:post.url' href='http://twitter.com/share'>Tweet</a>
   <script src='http://platform.twitter.com/widgets.js' type='text/javascript'/>

We need to take care of containing ' in title. If contained, page title is omitted after '. So we should check all page titles and convert from ' to &apos;.

Clean Ruby 1.9.2's remaining older gems manually

When I install Ruby 1.9.2 RC2, update gems and clean up older gems, but there are some remaining older gems like below:

> /opt/ruby-1.9.1/bin/gem update
> /opt/ruby-1.9.1/bin/gem cleanup
> /opt/ruby-1.9.1/bin/gem list

*** LOCAL GEMS ***

minitest (1.7.0, 1.6.0)
rake (0.8.7)
rdoc (2.5.9, 2.5.8)
test-unit (2.1.1)

What happened? In /opt/ruby-1.9.1/lib/ruby/gems/1.9.1/specifications directory, there are files like below:

> ls /opt/ruby-1.9.1/lib/ruby/gems/1.9.1/specifications
minitest-1.7.0.gemspec  minitest.gemspec  rake.gemspec  rdoc-2.5.9.gemspec  rdoc.gemspec  test-unit-2.1.1.gemspec

As you see, minitest.gemspec and rdoc.gemspec are remaining. So I remove manually and re-list gems.

> cd /opt/ruby-1.9.1/lib/ruby/gems/1.9.1/specifications
> rm minitest.gemspec rdoc.gemspec
> /opt/ruby-1.9.1/bin/gem list

*** LOCAL GEMS ***

minitest (1.7.0)
rake (0.8.7)
rdoc (2.5.9)
test-unit (2.1.1)

openSUSE 11.3 doesn't contain QML

Unfortunately, openSUSE 11.3 doesn't contain QML. So we cannot evaluate QML as out-of-box. We should use Qt 4.7.0 beta2 or should wait that Qt 4.7.0 final will be released. But QtCreator is ready for QML.
