Bringing back dial-up: the internet over SMS
summary
Builds an Android app and a Node.js server that tunnel HTTP over SMS via Twilio, stripping JS/CSS/images, short‑coding links into Redis, mapping common words and HTML patterns (Greek characters) to compress pages. A 250k‑char Google page drops from ~1,300 SMS to about 3 SMS and renders in a WebView in ~10 seconds (compared to ~45s dial‑up); limitations: no JS/CSS, no cookies, SMS is unencrypted, and delivery/order can fail.
