Trouble of the UNIX system

Today, I could not start an assignment on CG class. I could not execute any binary file, but they were compilable. I found the cause is due to the system itself, but I did not know well. I called a professional he works at university as an SE, and he solved the problem soon. I rewrote system file illegaly, so UNIX system could not call the c language library file. I remembered I wrote system file to set an application. Then, I had written an extra code which made an error.

Below are some useful UNIX commands I learned today.

setenv

unsetenv

printenv

Sunny day

It is sunny day. I felt a little hot in spite of winter. I wanted to go to the garden of university with my friend, but we had no time. We had to prepare for a midterm exam. We were unlucky.

Persimmons

I have many persimmons, and the taste is very good. I got them from my father. He said he soaked them into shochu after he plucked them. I asked him why he did that. The aim is to remove the astringency. That is the secret of so sweet persimmons. I love both my father and persimmons.

Honey

I ate honey on two slices of bread. It was very good. I have not eaten honey for a long time, so the taste was better. I like sweet breakfast like jam or honey. I love them, and I can not live without them.

I found the reason why people call their lovers honey.

Tired but Confortable

I went to university for swimming and topology class. I swam 1000 meters. I ran 2km after the class in spite of my tired body. I am very sleepy now.
