Go Channels: A Critical Re-evaluation

2025-04-13

A seasoned Go developer delivers a critical assessment of Go's channel mechanism. While acknowledging Go's theoretical grounding in CSP and its reliance on channels and goroutines, the author argues that their practical implementation suffers from several shortcomings. These include potential goroutine leaks, performance inferiority to traditional synchronization primitives, and complex interactions with other concurrency mechanisms. The author advocates for cautious channel usage, suggesting mutexes and callbacks as superior alternatives in many scenarios. Improvements to the channel system are proposed, such as enabling selection on condition variables and enhancing garbage collection to manage unused channels.

Running Python and Pygame on a $30 Handheld Linux PC

2025-02-01

This post details how the author installed Debian and ran Python and Pygame on the ~$30 Miyoo A30 handheld. After flashing spruceOS, a Debian chroot environment with Python 3, Pygame, and necessary libraries was created using debootstrap. To solve graphics and input driver issues, essential libraries were copied from spruceOS into the chroot. Finally, a script was written to add a Pygame game to the spruceOS interface, successfully running a custom game on the Miyoo A30. While a 90-degree screen rotation issue remains, this post provides a complete guide to running complex programs on a low-cost handheld.
