【No. 0013】Only Today, I Came Home Early

Dec 31, 2014 20:45
Basically, I have no day off.

As always, I went to my university and did my work.

As a matter of fact, I just like studying and don't want to get rest, rather than there are no day off.

Some juniors also came our laboratory.

That's because the deadline of their master thesis is approaching.

They look desperate, and maybe I might be like them next year due to my doctoral thesis deadline.

However, the new year's eve of this year, I came home early leaving juniors.

And now, I spend my time slowly while watching TV shows and eating oranges.

Best wishes throughout the coming year.

【No. 0012】Today, I read a bool titled "Gupta in Wonderland (Fushigi no k...

Dec 30, 2014 23:55
Today, I read a bool titled "Gupta in Wonderland (Fushigi no kuni no Gupta)".

In this book, Indian named Gupta living in the world of TOEIC test realize various things gradually.

I had took TOEIC tests several times, so when I read the book, I thought "It could happen!!" frequently and I enjoyed it.

For example, in the world of TOEIC, there are many laws as following;

1. A Flight will always delayed definitely.

2. A Photocopier will be broken or paper will run out always.

3. A reservation of dentist will be made change always.

4. Indian names of the world are Gupta or Singh always.

Besides, the other various laws are exist in this world.

I realized the world of TOEIC test is strange certainly.

Since now I know these laws, I think taking a TOEIC test become a little fun.

【No. 0011】OMG! I Caused A Car Accident! (ﾟдﾟ)

Dec 29, 2014 21:24
It was snowing a lot this morning.

After I shoveled the snow that was piled around my car, I was trying to back the car from the parking area.

I couldn't see behind securely due to the snow, and there is a parked car on my car's behind.

"Bump!" The sound made my face pale, and my heart was in my mouth.

The car's license plate and my car's left-side rear were dented.

However, there was nobody in the car and the owner was close by, so we could talk to each other immediately.

(I think these things were a blessing in disguise.)

First, I tried to call the police, but he said "You need not to do that."

As a result of our talking, it was decided only that I will pay a fee for repairing his car.

Definitely, I was relieved because there were no injured, and the car's owner was a good man.

I'll be careful from now on.

【No. 0010】Practice of A TOEIC Test

Dec 28, 2014 23:50
Since a TOEIC test is just a month away, today I practiced solve problems assuming an actual exam.

It took 2 hours to solve the 200 problems, and it took about 3 hours to score them and to understand their commentary, then I was very tired.

My score was 650 points... it's awful.

I have to acquire 730 points at least on the TOEIC test in order to satisfy graduation requirements.

But I think 730 points isn't enough because I have to write doctoral thesis in English next year.

From today, I will try to solve TOEIC problems every day.

And today, after I finished the practice, I played "The Legend of Zelda: Skyward Sword" that I bought six months ago.

It's really funny, so I'm afraid I can't stop playing it.

However, I decided the game play up to maximum an hour a day.

【No. 0009】I Gave an Xperia Z3 for myself as a Christmas Present.

Dec 27, 2014 23:46
Today, I bought an Xperia Z3 which is a smartphone made by Sony in an electronics store.

I could purchase it at 0 yen because I used MNP(Mobile Number Portability system) and then discount campaign of MNP was applied.

However, since the monthly fee is 1,000 yen during 2 years, so practically I bought it 24,000 yen.

It was a little bit late, but as a christmas present, I gave the Xperia Z3 for myself.

Hehehe.

【No. 0008】New Year's Greeting Card using Mandelbrot Set

Dec 26, 2014 23:14
Today, I wrote new year's greeting cards.

In Japan, there are twelve types of zodiac(animal symbol) for each year, and we often draw the animal in the new year's card.

The zodiac of next year is sheep, but I thought it's boring to draw sheep merely.

So, I searched sheep in the mandelbrot set which is represented as follows:

z_n=(z_n)^2+C,

where C is a complex number, and interestingly, this complex sequence represents fractal(fractal means the shape has many various self-similar patterns).

And after a while, I found sheep-likes shape in the square of the diameter 4.57321575822222e-8 which was centered at the coordinate (-1.74972831529409, -3.35584316649456e-10) .

I decided to use the sheep hidden in the mandelbrot set, and then, I drew sheep's eyes additionally and printed it.

[ Result of trimming and rotating and adding an eye. ]

Beautiful sheep shaped mathematical was completed!

【No. 0007】Large Cleaning and A Year End Party

Dec 25, 2014 23:54
Today, we performed a large cleaning of the end of the year.

I was so tired because we cleaned every nook and corner.

However, our room became clean and its environment is really comfortable.

After that, we held a year end party again.

It's the fourth time we had held the party this year.

We ate a hot pot cooking while watching a movie of Doraemon.
（Draemon is a Japanese animation character famous in Japan.）

When I watched the Draemon animation, I relived my childhood and sentimentalized.

Ah, I'm already an adult ....

【No. 0006】I Participated A Programming Contest.

Dec 24, 2014 23:16
This year, I have nothing to do with Xmas.

I went to school, researched, worked, came back to home and participated a programming contest.
And misery as well, I was crushing defeat in the contest.

The first problem of the contest demanded the result of A+B.
It looks like really simple and easy, however, it was forbidden to use addition/subtraction operator, and we could use multiplication/division operator and "if" sentence only (comparison operators are not included).
Furthermore, the code was limited to 1000 lines and the number of available variables was limited to 26.

I tried to solve this problem, and about 4 hour later, the contest finished while the problem is not solved.
(Accordingly, just one participant could solve it completely.)

Finally, the answer will be published, but I don't see it and keep trying to solve it by myself for a while.
Because I want to taste the sense of accomplishment and bliss.

Hehehe!
