Mon, 20 Apr 2026 00:30:29 +0800

I recently redesigned this blog. The visual direction came from GOV.UK Design System. I checked alphagov/govuk-frontend for implementation details, then asked codex-cli with gpt-5.4 to do most of the coding.

A Finder Resume Copy Issue

Sun, 17 Aug 2025 00:30:29 +0800

I hit a weird Finder copy failure the other day.

This was on macOS Sequoia. The copy failed halfway, and Finder said I could resume it. I didn’t really want to trust that.

Mesa EGL Notes

Sun, 07 Jul 2024 12:05:11 +0800

Mesa sits in the middle of most Linux graphics stacks. On a modern desktop it is usually the layer that turns EGL calls into driver operations, talks to DRM/KMS, and connects rendering APIs to the native window system.

Android Photo Export Pitfall

Mon, 17 Jun 2024 00:30:29 +0800

adb pull can mess up file timestamps when exporting photos from Android if you forget -a.

Emacs Dired Mimeicon mode

A Notification Design Idea

I recently saw the new front-screen design on the iPhone 14 pro series, which Apple calls “Dynamic island”, and that’s where I got the idea.

Cutefish Menu Bar Chameleon

macOS Big Sur introduced a new top menu bar behavior: the menu bar background color adapts to the desktop wallpaper, so it feels more integrated than before.

C++ PIMPL Pattern

Sat, 27 Oct 2018 12:22:11 +0800

PIMPL means pointer to implementation, or private implementation. It shows up a lot in C++ projects and libraries. The basic idea is simple: keep private data and methods out of the public interface. Put the class implementation details behind a separate pointer-owned class. This is useful when building a stable ABI for a C++ library interface, and for cutting down compile-time dependencies.
