AICoding
Oh My OpenCode is an orchestration harness on top of OpenCode, not a replacement. Install OpenCode first, run /init, then add the harness with bunx oh-my-opencode install. Includes fixes for opencode not found and stale OpenAgent commands.
AICoding
Install Codex CLI with npm i -g @openai/codex, then use the 5 tips that make it reliable: plan before implementing, set scope and non-goals, move repo rules into AGENTS.md, delegate to subagents, and always verify. Plus CLI vs App vs IDE and large-repo best practices.
Streamlit
Set up Streamlit in VS Code, run `streamlit run app.py`, fix interpreter and `command not found` issues, and debug common port and breakpoint problems.
Python
The __pycache__ folder stores compiled .pyc bytecode that makes Python imports faster. Learn why it appears, whether it is safe to delete, how to gitignore it, and how to disable it with PYTHONDONTWRITEBYTECODE.
Python
Learn how to run Python scripts in different ways, depending on your environment and skills. This guide covers command-line, IDEs, and file managers for efficient and effective script execution.
