Termtter Skype Public Chat Room

Developpers of a cool twitter client termtter have their own chat room the termtter lingr room. Unfortunatelly, Lingr is going to get closed. Accordingly I created the Termtter Skype Public Chat Room.

http://www.skype.com/go/joinpublicchat?skypename=ujihisa23&topic=termtter&blob=Rngw4xGf8Be5Ss0oxpe_wEHXO0SpFrAe4YOH1GwGYHtU84wInDRSQCxw4wePdYVZ

If you cannot join this room, feel free to contact me.

git-mv completion

Since one day, I've been unable to complete argument filenames of git-mv. So I've had to mv filename1 filename2 and then add git at the head of the command. It's too much of a bother.

Today I found the casus of trouble and its solution. Put the following patch:

Obviously, the cause was the change of git subcommands' usage.

enjoy!

Now Rubygems Can Generate a Graph

RubyGems 1.3.2 now has plugins feature. The gem plugins feature is like subcommands of git, and is able to be added easily.

• RubyGems 1.3.2: Now with Plugins
• rubygems now has plugins!

For example, rubygems can show a dependency graph of installed gem packages. Let's try!

$ sudo gem update --system
$ sudo gem install graph
$ gem graph

An error occured. I need graphviz library. OK.

Noooooooooo

After a struggle for two hours, I just found an ommision of the ! of shebaing. The first line of code was treated as just a comment.

Why Ruby doesn't have the IO.write method

While Ruby has a class method IO.read to read the whole contents of a file, Ruby doesn't have the corresponding method IO.write. The reason why Ruby doesn't have the class method IO.write is already mentioned by Matz in Japanese.

Q. Is there any positive reason why IO.write isn't there even though IO.read is there?

A. No. I have only the negative reason that IO.write won't be used as many times as IO.read. I'm also afraid the method causes users to waste memories. I ignore the symmetrical property.

I also found another disscussion about it in English.

Although Ruby doesn't have IO.write, we can define it in just three lines. That's OK. But, it's laborious to define it every time we need IO.write or to write equivalent one. There must be shortcuts.

I searched that from Rails' ActiveSupport::CoreExtentions and Merb's Extlib. There are a lot of utility methods, but there isn't IO.write! Does nobody feel bothered by it?

Move to Vancouver, Canada from Osaka, Japan

I took some photos and uploaded them:

• Flickr: Move to Vancouver, Canada from Osaka, Japan

At KIX

Ate Japanese lunch at NRT

That was very expensive. 1,000 yen!

Flight across the Pacific

That monitor system was broken. Even when we were arriving Seattle Airport, the monitor showed us that we were now on the Pacific.

Seattle! (SEA)

It was rainy that day. Seattle was a nice wooded town.

Ate breakfast at Seattle Airport

I ate Asian Veggie Wrap with coke. It was not bad.

And finally I arrived in Vancouver. The airport was badly crowded. I had to wait for the immigration for two hours! I never want to get lined up the immigration queue again.

Our new house

I was surprised that our new house was located in a such place. The view seemed very nice even if it was rainy.

The first day was rainy. The second day was cloudy. Since third day, it has been sunny! yeah!

We can see the Olympic Stadium from the window of our room.

Comparison between Japan, Canada and the US about the MBA price

• Japan: 214,800yen

• Canada(tax 12%, 1$ = 80yen): 159,920+19,190 = 179,110yen

• US(tax 8.5%, 1$ = 100yen): 179,900+15,291= 195,191yen

Canada is the country that sells the cheapest MacBook Air!
