Hacking Software Development with LLMs: A Workflow for Speed and Efficiency

This post details a highly efficient workflow for building software using Large Language Models (LLMs). The author breaks down the process into three stages: idea honing, planning, and execution. First, a conversational LLM refines the project idea into a detailed specification. Next, a reasoning model breaks the spec into small, iterative steps and generates corresponding code generation prompts. Finally, code generation tools (like Claude or Aider) implement each step incrementally, with testing at each stage. The author also covers handling legacy code and shares useful LLM prompt engineering techniques. While this boosts development speed, challenges remain, including team collaboration difficulties and downtime waiting for LLM processing.

One Year Debugging Sleep-Wake Hangs on Linux with AMD GPUs

2025-02-17

The author encountered a persistent issue where their Linux system, equipped with an AMD RX 570 GPU, would crash or hang after attempting to sleep, often resulting in a black screen upon waking. After over a year of intense debugging, involving journal analysis, systemd configuration tweaks, a debug shell, even Ghidra reverse engineering, the root cause was identified as an amdgpu driver bug related to VRAM backup during high memory usage. The solution, finally implemented, leverages the power management notifier API to preemptively back up VRAM before sleep, preventing memory exhaustion errors. This fix is expected in the stable Linux kernel 6.14 release.
