Sometimes I want to connect the AirPods2 headset to the Ubuntu computer. After recently reinstalling the system, I encountered a situation where the headset could not be paired. I hereby record the exploration process.

My small broken site is placed on a beggar host in a foreign computer room, and the code is hosted in a github private warehouse. When I push the code, I hope to automatically update the website. There are actions in github. You can write relevant logic by yourself and implement it on the runner of github.

In mainland China, the need for scientific Internet access has always existed for technical personnel and certain groups. From the earliest VPNs to Shadowsocks, to V2Ray, and the latest Xray, the goal is to freely access the internet and obtain necessary information. This article describes the configuration of scientific Internet access in command-line mode on a Linux PC.

It turned out that due to open source licensing issues, the kernel doesn't include a corresponding ZFS processing module like ext4. If there was a dispute, Oracle's lawyers would send a letter. Without further ado, since Ubuntu officially provides a corresponding file system option, and BSD and other systems also use the ZFS file system, it must have its unique advantages. For the poor, the ZFS snapshot feature is definitely practical. The test process is as follows: LVS deployment
