琐记

我没有离开，只是暂时无言。日子还在进行，一切都不是终点，只要活着，就会有很多麻烦也会有幸福。不是吗。
好久没有更新日志，都忘了上次写东西是什么时候。应该过了蛮久了吧，你们好吗？
Only you can hear
in Diary
When I was a kid, I loved a song by Jay Chou termed Only you can hear. I remember the bland and uninspired story in the MV about a couple of young lovers. The story about the meeting, falling in love, disagreements, arguments, and separations has little to do with my life of the time. While that was the story I understood as a child - the importance of communication in intimate relationships. So much so that I wanna steal the song title.
She told me she was following the real-time result of the 2020 U.S. presidential election.

The common usages of SSH login
in Note
SSH is a network protocol for encrypted logins between computers.In 1995, the Finnish academic Tatu Ylonen designed the SSH protocol, which became a fundamental solution for Internet security. This article is my notes on configuring SSH logins and summarizes the common uses of SSH.
There are roughly three ways to use SSH to log in to a remote Linux server: password, key, and certificate. This post will focus on how to use these three methods of SSH login to remote Linux and will not go through the SSH principles or the underlying protocols. Furthermore, this article only discusses Linux and macOS-based SSH usage. If you want to use ssh in windows, you need third-party software support.

人群中的我身边没有陪同者，我拥有的仅仅一个相伴三年的背包，但不意味着我始终孤单。我曾有过美好的回忆，此刻亦拥有挂念之人，也许他们同样也在某一刻思念着我。想到如此，不禁如释重负，我低头对挪不动的双腿默默说，走吧，走吧。
