Hi all,
I'd just like to say that I am all right after the earthquake that occured yesterday in Japan.
Most people have normal life here in Tokyo.
TVs and newspapers say that a power plant nearby has meltdown but, at least for now, it doesn't seem very serious.

Socket.
I was solving the puzzles (Mortal Coil etc.) with C++. So I could just reuse a function for communicating with the server. That was the easiest way for me at that time.

I did it with C++, but I'd recommend C# for today.

Thanks for the invitation, Teebee.
I tried some problems there.
It's fun!

I think it's still lengthy:

Threading sounds good. I couldn't do that because I used a laptop with Celeron M (single core, single thread).
Also, I didn't even use SSE (just because I was lazy :-)).
So, I'm pretty sure we can do much quicker.

Hi, it took 18 seconds for me to solve the last level.
I think we can do much quicker if we use a better algorithm and a better computer.

How do cities cast radio signals?
To my understanding about cities, only "build" is called and "think" is not called. And "build" can only return an integer, thus unabe to cast radio.
Am I missing anything?

d) users who can find those three ...?

Hi, There are some C libraries that handle images. But, if you are really interested in understanding images, then I first recommend you to learn some major image file formats. It should be fun. BMP and TGA are relatively simple ones, so I think you can start with one of them. Well, I solved this ch...

After optimization, my code has become 189 instructions long.

Thanks for enjoying this challenge

My code is 370 instructions long.

The example runs exactly the same way on both PHP and JS to me.
What difference do you have?
What do you mean by "include"?
