Reads your Bluesky and Mastodon home timelines, asks a language model which posts are about topics you'd rather avoid (politics, war, whatever you list), and writes a calm, merged timeline to an HTML page.

• Works with Claude, a local model (Ollama, LM Studio, llama.cpp and others), or any command-line tool that reads a prompt and prints a reply.
• Only uses the Ruby standard library (Ruby 3.1 or later).
• Remembers verdicts, so each post is sent to the model only once.
• Filtered posts are listed at the bottom of the page by author and topic only, without their content, so you can check for mistakes without reading them.

#!/usr/bin/env ruby
# Joins videos end to end into one video, in the order they are given. The new
# video is as long as all of them added together. Nothing is cut.

# rate of the first, and a video of a different shape gets black bars rather
# than being stretched. A video with no sound is joined with silence, so the
# sound of the others stays lined up with the picture.

❯ You seem to have discovered a lot about the map "scripting" in Zanac. E.g. @tools/decode_mapscript.py . Can you summarize what the
  script for the first area does for me?

⏺ Here's the area‑1 script (bank5 $A411, decoded with tools/decode_mapscript.py; commands documented at src/bank7.asm:4617
  MapScriptExecCmd).

  How to read it

  The script is paced by map distance $A2/$A3 — one unit per generated map row, not per frame. At the default 2.0 px/frame scroll, ~4
  frames per row. Each command fires when distance reaches its trigger, so everything below is at a fixed position in the level, never

Q:

in super mario bros for the nes, are walking, running, and jumping speeds identical for both small mario and super mario?

A:

No, the speeds are not identical — small Mario and Super Mario have the same walking, running, and jumping speeds in the original NES Super Mario Bros., but there is one critical difference: small Mario dies on any enemy touch, while Super Mario shrinks to small Mario first.

Let me verify this more specifically about the actual speed mechanics:
