### Description

Linux 下有些时候我们运行一个进程需要一直挂着（这就是 VPS 的意义啊……），这时候需要把前台进程放到后台去。一般可以用 screen，但是如果这种后台进程挂多了，每个都开一个 session 会很不方便。前几天配置 aria2 的时候看到一个神奇的操作：可以配置成一个 service，直接 service aria2c start/stop/restart 就可以了！

## Description

Ivan wants to make a necklace as a present to his beloved girl. A necklace is a cyclic sequence of beads of different colors. Ivan says that necklace is beautiful relative to the cut point between two adjacent beads, if the chain of beads remaining after this cut is a palindrome (reads the same forward and backward).

The cool breeze blows gently, the flowing water ripples steadily.

"Flowing and passing like this, the water isn't gone ultimately; Waxing and waning like that, the moon doesn't shrink or grow eventually."
"Everything is transient in a way and perennial in another."

Kanno doesn't seem to make much sense out of Mino's isolated words, but maybe it's time that they enjoy the gentle breeze and the night sky — the inexhaustible gifts from nature.

Gazing into the sky of stars, Kanno indulges in a night's tranquil dreams.
