Patch Zig Stdlib

Zig is great. But its aggressive minimum Linux kernel support policy—only supporting versions newer than the current Debian LTS kernel, 5.10—makes it unusable on older systems like Kindles, Termux on Android, and old servers.

This guide introduces a simple, minimally invasive patch for the standard library to maximize compatibility with these older devices.

What not supported?

The specific syscall that's breaking compatibility with old kernels is statx, which was introduced in Zig 0.14 (replacing POSIX's fstat).

It appears to be [called in only two places in the standard library](https://github.com/search?q=repo%3Aziglang%2Fzig+language%3AZig+linux.statx%28++NOT+path

MECHREVO Wujie 14XA (Ryzen 7 8845HS) Reverse-engineering

This log documents ACPI calls and driver calls found through reverse engineering the MECHREVO Wujie 14XA laptop (marketed as 机械革命无界 14X 暴风雪版, or Mechrevo Boundless 14X Blizzard Edition).

I am playing with:

• BIOS version: N.1.14MRO17
• AP (control center) version: 5.56.51.17

"How did you capture these calls?"

Network Manager Auto Reconnect

Motivition

I have an Orange Pi that connects to the network via WiFi, and since my network is not very stable, the wireless router side often forcefully disconnects all devices, requiring manual reconnection. This is an annoying thing when I'm out: first, I have to figure out how to SSH to my Pi!

The network manager I use is NetworkManager, which is very modern and user-friendly. Unfortunately, until today its developers were not interested in adding an option to automatically reconnect to hotspots.

In this issue, some developers have suggested using the dispatcher to accomplish this. Well... I wrote a simple script to do this. It will try to restart the NetworkManager service 3 times when the network is disconnected (down event received).
