In plain words

Compression-Resistant Data Transfers is a tool that enables efficient file sharing while maintaining data integrity regardless of compression attempts. Designed for developers and IT professionals who need reliable data transmission, it stands out by guaranteeing that files remain uncorrupted even when passed through systems that apply compression algorithms. The project is available on GitHub for those seeking transparent, open-source solutions for secure data handling.

From the sources

This repo contains some experiments that involve encoding arbitrary data into video files that survive Youtube compression. The current solution works 99% of the time and only rarely encounters errors in practice. It works 100% of the time under ideal conditions (i.e. when not round-tripped through Youtube). When encoding some data, each byte is converted to a "tile", which is a rectangle of arbitrary size filled with one of 256 colors. The "palette" used for these colors was specifically tuned to maximize resistance to Youtube's compression. One "frame" of video is made up of as many tiles as will fit. In a 720p (1280x720) video, for example, we can fit 3600 16x16 tiles, or 3.6kB of data.…from github.com

    Overfitted a 900KB Transformer to Compress a 100MB CSV into 7MBJun 2026 · ▲112

    I built an experiment that uses an overfitted transformer and arithmetic coding to compress individual files. Instead of training the model to generalize, I train a 900KB transformer to memorize a single file and predict the next byte. Those predictions are fed into an arithmetic coder to produce the compressed output. On a 100MB NYC taxi CSV, it compresses to about 7MB (~0.5 bits/byte). On a 100MB slice of enwik9, it compresses to about 21MB (~1.68 bits/byte). It's pretty slow right now (roughly 20–30 minutes of training and 45 minutes each for compression and decompression on my…

  • I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

  • Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
