Going through it & really enjoyed it. 2147483647 is a great exhibit. Funny how a number you recognise from debugging has a whole other life in mathematics. A museum for numbers is a lovely idea.

Perhaps it still is, if vibe was not really looking at code (but still at output) tbh, this has worked better for me than one shotting with /goal and /loop.

Show HN: Ez FFmpeg – Video editing in plain English

josharsh — Sat, 27 Dec 2025 08:45:46 +0000

I built a CLI tool that lets you do common video/audio operations without remembering ffmpeg syntax.

Instead of: ffmpeg -i video.mp4 -vf "fps=15,scale=480:-1:flags=lanczos" -loop 0 output.gif

You write: ff convert video.mp4 to gif

More examples: ff compress video.mp4 to 10mb ff trim video.mp4 from 0:30 to 1:00 ff extract audio from video.mp4 ff resize video.mp4 to 720p ff speed up video.mp4 by 2x ff reverse video.mp4

There are similar tools that use LLMs (wtffmpeg, llmpeg, ai-ffmpeg-cli), but they require API keys, cost money, and have latency.

Ez FFmpeg is different: - No AI – just regex pattern matching - Instant – no API calls - Free – no tokens - Offline – works without internet

It handles ~20 common operations that cover 90% of what developers actually do with ffmpeg. For edge cases, you still need ffmpeg directly.

Interactive mode (just type ff) shows media files in your current folder with typeahead search.

npm install -g ezff

Show HN: AI Terminal Course – Learn AI Engineering Like Learning Vim

josharsh — Wed, 12 Nov 2025 07:19:21 +0000

I spent months watching AI tutorials on YouTube. Took notes. Felt like I learned a ton. Then I sat down to build something and... couldn't. I didn't actually understand a lot of stuff!

The problem: Passive learning doesn't work for engineering skills.

What makes this different:

• You TYPE every command (no copy-paste) • You SEE real API responses (not fake demos) • You PAY real costs (~$10 total) • Terminal-only (no context switching)

Think vimtutor, but for AI engineering.

20 modules covering: - Tokens, embeddings, RAG - Structured outputs, tool calling, agents - Cost optimisation, evals, production monitoring - Real OpenAI/Anthropic API calls

Try it: npx ai-terminal-course

No installation. Just run it.
