Good Bye, Osaka

Had 3 months (October to Jan 2012) research attachment in Imase Lab of Faculty of Information Science and Technology, Osaka University.

It’s time to say good bye.

Thanks for all the guidance and care. I will miss you all >_< ……………

A memorial.

p/s: 残念desu, I have yet to visit any MEIDO CAFE.

ChromiumOS/Chromebook

I must say, I like the idea of  ChromiumOS (or Chromebook).

My girl spends most of her leisure time on movies and Internet – surfing the web, chatting in Facebook, watching movies, etc. And Chromebook just happens to suit her lifestyle.

The Chrombook does a little thing more than just a browser-machine. Besides surfing the net with Chrome, you can play music and video in Chromebook without connected to Internet. There is a “file manager” in Chrome that allows you to browse the files inside the solid-state harddisk or the external SD card.

So, why Chromebook? Well, it has 8-second boot-up time, hassle-free user experience, no annoying viruses or patches, thousands of web-apps and games. They are installation-free. You just need to sign-in and used.  Unfortunately, the sales of Chromebook is not doing well in US (2011). However, believe me or not, Chromebook will be a big thing after html5 is mature, perhaps after 2015.

Uniqueness of Mathematics

A very meaningful sentence from Introduction to Proofs and Real Analysis, written by Richard C. Penney:

“There is a fundamental difference between mathematics and other sciences. In most sciences, one does experiments to determine laws. A “law” will remain a law, only so long as it is not contradicted by experimental evidence. Newtonian physics was accepted as valid until it was contradicted by experiment, resulting in the discovery of the theory of relativity.

Mathematics, on the other hand, is based on absolute certainty. A mathematician may feel that some mathematical law is true on the basis of, say, a thousand experiments. He/she will not accept it as true, however, until it is absolutely certain that it can never fail. Achieving this kind of certainty requires constructing a logical argument showing the law’s validity–i.e. constructing a proof.”

Something in My Mind

Let A and B be two events of an experiment.

Given a statement:
A implies B but B does not imply A (or simply A implies B).

e.g.
A: Otaku.
B: Watch Anime.
That is: Otaku watches Animes. But those who watch Anime may not be an Otaku.

In Set Theory, we may say A is inside B but B is not inside A. Or A \subset B.

To put them into conditional probability:

\Pr(B|A)=\frac{\Pr(B \cap A)}{\Pr(A)}=\frac{\Pr(A)}{\Pr(A)}=1

\Pr(A|B)=\frac{\Pr(A \cap B)}{\Pr(B)}=\frac{\Pr(A)}{\Pr(B)}\leq 1

 

Thus, the statement: “A implies B but B does not imply A” may be written as:

\Pr(B|A)=1 and \Pr(A|B) \leq 1.

Proofreading

Writing report to supervisor is a pain. Not to mention writing for public.  For that reasons, a non-English speaker like me have no choice, but to use the online free/paid service to improve my writing.

Geany – Python Source Code Editor

Geany is good Python source code editor in as it fulfills my required features (i) code-folding and (ii) dark colour theme.

By default, Geany only shipped with white color background. However, different color schemes can be downloaded from here. Currently I am using the geany-dark-scheme.

*In Ubuntu, one of parameters of the config file “filetypes.python” should be: stringeol=0xE23636;0xe0c0e0;false;false.

To Meet the Ultraman


Out of nowhere, I have this idea to visit the motherland of Ultraman.

To see how they train the Ultraman.

To learn how they use the laser beam to kill the raksasa.

Update:

16-Jun-2011. I am still waiting the invitation letter. Will my plan be cancelled?

17-Jun-2011. Finally got the invitation letter. Now submit with the application to my institute.

21-Jun-2011. HoD approved RAtt.

1-July-2011. CoE is still in processed. Without CoE I cannot apply VISA.

5-July-2011. R-Leave application has been rejected due to insufficient publication (I guess).  Applying I-Leave now.

6-July-2011. Management agreed to change full I-leave to half A-leave and half I-leave.

4-Aug-2011. Haven’t got the CoE…. hm.. such a long time.

8-Aug-2011. Finally see some light from Osaka. The accommodation should be OK now. I am waiting a very important document now.
