Finish to read C++ GUI Programming with Qt 4

I've finished to read C++ GUI Programming with Qt 4 and to code its tutorials finally. My sample of last widget on this book is below:

This book is useful for my basic learnings. But this book had published when Qt version was 4.1, and 2nd edition of this book is for Qt 4.3. Of course, current version is Qt 4.5 and Qt 4.6 will be released soon. So I hope someone will publish Qt 4.5 / Qt 4.6 book in English ... or in Japanese if possible.

Evaluate RubyMine 2.0

While NetBeans 6.8 RC1 has never released (and been postponed 3 times), JetBrains releases yet another Ruby IDE ... RubyMine 2.0.

It's same with NetBeans that RubyMine runs on JVM. But it's not same with NetBeans that RubyMine 99 dollars while NetBeans is 0 dollars. So I have signed up its 30-days evaluation and install on openSUSE 11.2.

And I using it some days and I'm not feel bad. When evaluation period will be over and If NetBeans 6.8 FCS will not be released in that time, I will pay 99 dollars for RubyMine!?

Release of NetBeans 6.8 RC1 is postponed three times!

The release day at first plan was 11/09. The release day at second plan was 11/15. And the release day at latest plan is today, 11/24. But today, it is postponed also.

Installing QtRuby on Ruby 1.9.1 from openSUSE source rpm

At 1st, install Ruby 1.9.1 with same instruction of this article:
phosphorescence: Install Ruby 1.9.1

Then I should go to install QtRuby with source from repository, but smoke/generator of QtRuby is still unstable yet as I had write in this article:
phosphorescence: Confusing about smoke/generator

So I decide to install from source RPM package of openSUSE 11.2 - my own environment.

What version of Qt and QtRuby are bundled on openSUSE 11.2?

To see the version of Qt and qmake, type the command below:

> qmake --version
QMake version 2.01a
Using Qt version 4.5.3 in /usr/lib

Qt on openSUSE 11.2 is version 4.5.3 ... latest stable version.

And to see the version of QtRuby, familiar commands below:

> rbrcc -version
Ruby Resource Compiler for Qt version 4.5.3
> rbuic4 -v              
Qt User Interface Compiler version 4.5.3   
> rbqtapi -v             
QtRuby 2.0.5 using Qt-4.5.3

QtRuby on openSUSE 11.2 is version 2.0.5 ... it's trunk version.

I have installed openSUSE 11.2

I have installed openSUSE 11.2 on this weekend. It was very easy because of YaST installer and KDE 4.3 is more beautiful than older openSUSE's one.

But there is one curious point. It's non-English directory names in home directory. For example, my environment is below:

openSUSE 11.2 release memorial party

In yesterday, openSUSE 11.2 release memorial party was held at Tokyo, Japan. This party has became a count-down party because iso images of 11.2 were not mirrored yet, and had finished mirroring at the end of party.

So I try to download DVD iso image from now.

Ruby initialize puzzle (more exercises)

(continued from phosphorescence: Ruby initialize puzzle (answer part))

If you want to call both initialize methods, you should write initialize method of Bar module like below:

module Bar
  def initialize(b)
    super
    puts "#{b} World"
  end
end

irb(main):018:0> Sample.new('qux')
Hello qux
qux World
=> #<Sample:0x256e918>
