Cancun Climate Change Conference

It's not over yet.
But I would like to say that the president of COP16/CMP6 has done a great job. She coordinated and lead the conference toward a positive way.
At the beginning of the Informal meeting of the COP 16/CMP 6 President, resumed 2nd meeting, which is currently going on, the participants gave standing ovation to her.

Derecho de la madre tierra

I think that's what the president of Bolivia said, meaning the right of the mother earth.

Derecho de naturalesa

I think it means the right of the species - all the species on the planet have the right.

This is what I understand for a long time about population growth. It's just that this video explains it visually very clearly.

Soutenance au doctrat - c'était formidable

J'ai eu de la chance d'assister à la soutenance au doctorat à l'université.

Le candidat, les professeurs, les étudiants, les familles et les amies – tout le monde était très gentil et poli à moi. Je vous remercie tout le monde.

C'était une experience merveilleuse.

Cette soutenance me rappelait des souvenirs du temps ou j'était dans le domaine universitaire. Ça me manque beaucoup. Je voudrais y retourner.

I had a chance to attend a doctoral defense at a university.

The candidate, the professors, the students, the families and friends, everybody was very kind and polite to me. I would like to express my appreciation to everybody.

Installing Ruby 1.9.1 with Ruby Version Manager (RVM) on Mac OS X Snow Leopard

For some reason, Ruby 1.9.1 didn't install on my Mac OS X Snow Leopard because of an error:


Error running 'make ', please check /Users/home_dir/.rvm/log/ruby-1.9.1-p378/make*.log


The error in ~/.rvm/log/ruby-1.9.1-p378/make*.log:


compiling readline



readline.c: In function ‘username_completion_proc_call’:
readline.c:1159: error: ‘username_completion_function’ undeclared (first use in this function)
readline.c:1159: error: (Each undeclared identifier is reported only once
readline.c:1159: error: for each function it appears in.)
make[1]: *** [readline.o] Error 1
make: *** [mkmain.sh] Error 1


So compiling Ruby 1.9.1 with the default readline installed on Snow Leopard didn't work.

By looking at "rvm --help" or ~/.rvm/README, there is an option to specify custom configure options, i.e. -C|--configure. Also there is a flag to force ./configure on install even if Makefile already exists, i.e. --reconfigure.

So I installed readline with MacPorts and installed Ruby 1.9.1 with the option and the flag:


$ sudo port install readline

$ rvm install 1.9.1 --reconfigure --configure --with-readline-dir=/opt/local


Then installation succeeded.
