Bringing back dial-up: the internet over SMS
summary
Builds a working text-only browser: an Android app in Java that sends URLs to a NodeJS + Twilio server, which fetches pages, strips CSS/images, whitelist-tags forms/anchors, replaces common words and long words, maps links to short tokens stored in Redis/Reddit, and encodes frequent HTML patterns into Greek letters. A Google HTML (~250k chars) goes from ~1,300 SMS to three SMS; pages load in ~10s over SMS. Limits: 160-char segments, unordered delivery, plaintext SMS is not secure.
