# raphlinus/nibnib > A 4bpp image compression format tuned for extreme decompression speed, originally for DVI output on microcontrollers like the RP2350. It uses a delta palette and decodes two pixels per input byte. - Magnitude: 2.7 out of 10 — Steady - Stars: 45 total · +25 stars measured 2026-11-01, 21:22–22:50 UTC - Star trust: star growth looks organic - Category: Hardware, IoT & robotics · Language: Rust · License: Apache-2.0 · Created: 2026-10-30 · Last push: 2026-10-30 - GitHub: https://github.com/raphlinus/nibnib · Page: https://gitnova.dev/en/r/raphlinus/nibnib ## Useful for - Embed the decoder in microcontroller firmware for DVI display output - Compress sprites or backgrounds to 4bpp to save memory on embedded devices - Study the asymmetric encoder using Floyd-Steinberg error diffusion ## Why it’s here - Star-counter measurements on 2026-11-01 (UTC), 21:22–22:50: 20 → 45 stars (+25). This is the change over that interval. - The repository is 2 days old and already has 45 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet. - Hacker News: “Nibnib: Image compression with extreme decompression speed” — 61 points, 2 days ago. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 2 - Issues and pull requests: 0 - Watchers: 0 - Average over the last week: 10 per day - Usual pace: too little history (under two weeks) - Stars in the last hour (measured): 17 ## Stars per day, last 3 days (oldest → newest, today is partial) 2026-10-30 … 2026-11-01: 3, 0, 25 ## Hacker News - Nibnib: Image compression with extreme decompression speed — 61 points, 7 comments: https://news.ycombinator.com/item?id=50299811 ## Spotted in now - Spotted on Hacker News ## More in this category 1. **physicsdolphin/nv-uefi-unlocker** — 7.3 · Early signal · Hardware, IoT & robotics · Rust · +397 stars measured 2026-11-01, 00:02–22:45 UTC UEFI pre-driver unlocker for NVIDIA GPUs (RTX 20/30/40) that runs a firmware transaction chain before the driver loads to activate hidden GPU performance.

It is not a quality score. Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
