Last night, I enjoyed reading "Owari-monogatari(latter)" written by Ishin Nishio-san.

In the book, the scene that the hero and heroine competed in singing songs with scores from the karaoke-machine appeared.

As an engineer, I can determine that the score is not trustworthiness absolutely.

The parameters of the machine must be tuned by engineers.

I can estimate how the engineers make the score algorism.

(1)analysis of key frequency, (2)calculation of the time between specified points of sound, (3)making score as synchronic ratios from the (2)(3).

Maybe there looks like the above three points.

No engineer tries to load another function from the view points of memory and CPU and have spirit to do them.

According to the above parameters, the score becomes worse, the better she sings a song.

So, I think that Ms. Hitagi Senjyougahara doesn't let her down.

When I was a college student, there were many branches that showed "Computer fortune-telling" in college festival. I know well that are squiffy doo.

My wife who majored in English literature input the programming code to personal computer.

"Great! Did you design the algorism?"

I was surprised to heat it from her, she said,

"I just input meaningless many characters from a PC magazine"

The period absolutely existed that

Everybody believe anything with the word "computer”, and everybody respected me only because I could use computer.

Once, the days made me happy overwhelmingly with no reason.
