I am protanomaly...

Submitted by admin on

Peam just finish his version of street fighter puzzle and I while i was playing with him, I had problem detecting a yellow gem from a green gem. I can detect, but hardly. I have to adjust the color value of the gem a bit so that I can clearly distinguish green from yellow. That is quite strange coz other guys in the lab can tell which one is green or yellow very easily.

So I took Ishihara Test, and it turned out that I am a color blind :O. Furthur investigation at wikipedia reveals that I am a kind of protanopic, i.e., having problem with the red color (so that I have a problem telling yellow and green apart). On the Ishihara test, i pass 4 out of 6. I cannot answer the number in the bottom test. Well, there are two kinds of protanopic, protanomaly and protanopia. The first one is anomaly, i.e., lesser sensitivity to the red color (both saturation and brightness) while the other is completely red defunct. I am protanomaly (the web said that it is about 1% of male population for white ppl.) Most color blind people is Deuteranomaly, green-weekness.

Linux Library

the stupidity attemp

I have to set up something.. (linux box, kind of..) but there are some problems about shared library. I never understand nething of shared lib, except that it ends with .so. After a few googling around, here are some useful links.

http://www.tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html http://www.visi.com/~barr/ldpath.html

Here are some new knowledges for me

  • shared libraries are stored in /usr/lib or /usr/local/lib with a few exception for the very important ones used while booting which are stored at /lib.
  • the number behind .so (e.g., libvorbis.so.3.0.1) is the major and minor version of the library. Usually, the actual file is fully qualified and symlinked to the less clarity name (e.g., libvorbis.so.3.0 and libvorbis.so.3 and libvorbis.so are symlinked to the libvorbis.so.3.0.1).

In Joy of a Touch of a Good Story

Submitted by admin on

I always feel excited when experiencing a good story. A good story differs from person to person. I, myself, define a good story as ones that make me joy. Recursive definition, though, but it is the most correct definition. Anyway, the common of a good story is that it provides some good idea, some vista to which I never considered, a conspiracy that is hard to predict, blah blah blah. I love this, dunno why. Reading a good manga, playing FF series or other RPG with deep story, a nice novel, all of these make me happy. The recent one is The Moon is a Harsh Mistress. This is one of a good story. (I would not deny any PR money from ASK Media. Just finished it this morning. The concept propsed by Prof. de la Paz in the story is quite, well, in Aj. prabhas's words, ถูกจริต. The story is not quite complex as I expected but it is enough to keep me reading.
