If you are using a lightweight Linux desktop environment built with Wayland Compositor (such as Labwc, Sway, Niri, etc.), you will often encounter the problem of connecting Bluetooth headphones or Bluetooth speakers in daily use.

There are many screenshot annotation tools for Linux. I have used Swappy, Ksnip, Flameshot, etc., and I recommend Satty.

Chinese input under Linux is a long-standing problem, and I've written many articles on it. Since the new versions of Chromium and Electron, I haven't encountered the problem of not being able to input Chinese for a long time. However, recently, while playing Dota 2 at home at night, I suddenly found that I couldn't type Chinese (the candidate box wouldn't pop up!). Switching to the terminal with Ghostty, Firefox, and Obsidian didn't solve the problem either. My teammate picked Nyx Assassin, reached level 6 but didn't gank and instead stayed in lane hogging carry resources, so I was frustrated because I couldn't type Chinese (I could only type Pinyin).

A while ago, I mentioned that after connecting log monitoring to my website, I discovered that someone was maliciously scanning it every day. The scans resulted in a lot of 404 access records, wasting bandwidth and hindering my troubleshooting. The online world is treacherous; there are always malicious people trying to harm me.
