Now I'm challenging project euler in scheme. Project euler is, with the words at the site, "a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve."

At first, scheme was not comfortable language for me because I have studied scheme only in CS class in university as one of functional languages several years ago. Now I enjoy to solve problems in scheme, using another part of my brain than thinking with procedual language like C.

You can see my works at hatena diary. Although additional descriptions is written in Japanesse, you could understand my program if  you are interested in project euler and/or scheme.

I tried John Resig's processing.js, which is processing implementation on javascript.

This is a program to draw the Sierpinski carpet fractal.

var max = 3;
void draw_iter(x,y,w,h,n){
   var wn = w/3;
   var hn = h/3;
   pushMatrix();
   translate(x,y);
   rect(wn,hn,wn,hn);
   popMatrix();
   if( max <= ++n ) return;
   for( var i = 0; i < 9; i++ ){
      if( i == 4 ) continue;
      draw_iter( x+wn*(i%3), y+hn*Math.floor(i/3), wn, hn, n );
   }
}

void setup(){
   size(144,144);
   background(120);
   stroke(255);
   draw_iter(0,0,144,144,0);
}

As you see, it's quite simple. You can see the output picture  of this program in my another blog

A weeks ago, twitter in Japanese was released. on 3rd May, A member of Twitter Japan (a.k.a @twj) hold off-line meeting in Yoyogi park, Tokyo. Unfortunately, however, it was raining, but more than ten people came there. @twj gave us two sticker to each people.

Do you agree Flickr videos? Of course, I agree.

If you can't accept Flickr video anyway, why don't you use my greasemonkey userscript?

When a page listing images including videos is loaded, what is shown at first is not a embed flash object but just a image of its first frame. It is not until you click 'play button' image that a video object is loaded. And, the video plays automatically when you see a page for a certain video. However, a first frame image is loaded in HTML and hidden by CSS.

So, hiding 'play button' and with some DOM scriptings, this greasemonkey takes you non-video flickr-verse as before although I don't think it is fun.

If you are a pro member of flickr, you can see referrers from which they came to your photo pages in your flickr stats. In those stats pages showing referrer s, not a whole url, but only query parameters are displayed if domain of a referrer is search engine such as "yahoo.com" or "google.com".

However, it supports only referrers of major search engine and doesn't support those of other domains.

To improve this, I made a greasemonkey user script for firefox.  I'm sorry that it should be configured to display query parameter of domains you want to see. This sciprt also supports to decode non-ascii query parameter (see a image on the right). Please let me know if you know other domains whcih may have query parameter. I will update my script.
