Typesetting pseudocode in Latex

Tuesday, January 27th, 2009

Searchs on google for typesetting pseudocode in latex usually refer you to the algorithm/algorithmic package. So it seems that it is the most recent/popular/complete package.

Yet somehow it is not included at all in any package in ubuntu, and it was reasonably difficult (read, it took me 5 or 6 google searches and around 20 minutes) to find the repository for the package online to download it.

So let’s change the meta. Here is the link.

On other news, I’m looking for people with Mario Kart Wii to exchange friendcodes, to play online and mainly compare scores for their monthly challenges.

Last.FM

Tuesday, November 11th, 2008

Today I have finally discovered Last.FM. It is an internet radio service with a large collection of artists and music.

In the past, I have used music successfully to help myself concentrate whenever I wanted to study. At that time, I used the now defunct Pandora Radio (not really defunct, but unusable outside the U.S., which in practice means the same to me).

I think I have said it in previous posts, but I was having difficulty recently concentrating on my current tasks in my research. Today, surfing around, I stumbled on last.fm - not exactly a new website, but I never used it before.

My first contact was positive. Write in Beethoven in the search box, click play - there you go, a nice “Beethoven Radio”. Creating a profile to make a more personalized radio is a bit less intuitive, though - lots of clicks to add an artist to your profile, and you can’t play your own library until you have 15 artists. Of course, you could only listen enough reccomendations to fill up the quota and have your own library. That said, I was quite content with the automatic reccomendations he gave me when I assembled my study set.

The problem was when I tried to separate my study set and my personal set. I like to listen to instrumental music when I’m studying. But when I’m not, I have a more varied musical taste. In Pandora, I could set up a number of different radios, but it seems that last.FM only allows each user one radio station. Also, the reccomendation system can’t seem to find a good “middle ground” between multiple different music styles. After making another radio station with a few MPB artists and a few Rock artists, the reccomendation after a while started sending me only MPB songs, and no rock songs. Having a more varied sample would be nice.

Now, it seems that this can be circumvented by creating multiple users, each dedicated to a different style. I’m not sure if that is the best solution, though, and I’m willing to hear more.

Where in the world…

Saturday, February 9th, 2008

Recently I saw in a forum this very neat flash based game. It is a geography quiz, where you have to try and get right the position of many cities in the world.

Try it!

That’s a lot of people.

My everyday commute goes something like:
Komagome->Nippori by JR yamanote
Nippori->Kitasenju by JR joban
Kitasenju->Kashiwanoha Campus by Tsukuba Express

This is an inverse commute, in the sense that I leave tokyo to study in the suburbs, while the vast majority of people leave the suburbs to work/study in tokyo. So I almost never get full train.

The “Nippori->kitasenju” leg of the trip, though, is particularly full in the opposit direction. If I happen to exchange trains in Nippori before 9:00 in the morning, I can see what is literally an army of commuters marching in my direction, as they leave the joban line to go to both sides of the platform. You can hear their footsteps ressonate.

Anyway - today I saw an interesting sign at Nippori - “passengers to Akihabara, please change trains at ueno, and not here”. To get to akihabara from Nippori, you can finish riding the joban line until ueno, and then change to the yamanote line, or you can just get off here and change to the yamanote line right away.

So I was a bit puzzled by this - Nippori is a much smaller station than ueno, with much less lines going through. It is much easier and faster to exchange trains here. Until I read today’s newspaper - it seems that the yamanote line in this section has been determined as the most packed train line in all of Japan, with a 211% fill rate of the train wagons.

I’m so glad to do reverse commuting :-)

A Chimp never forgets

Tuesday, December 4th, 2007

An interesting article where scientists compare the memorization abilities of chimps and humans - the test is to try and memorize a sequence of numbers that briefly flash across the screen.

http://news.yahoo.com/s/ap/20071203/ap_on_sc/chimp_memory_1

I wonder if the fact that humans try to process the meanings of the numbers affects the results. I hope that they also do a test where, instead of numbers, meaningless symbols are used.
