Advent Calendar 9

While solving some local work tasks, I had a wild idea: what if data packets were sent again over mobile networks. I could not come up with anything better than proposing data transfer in DTMF format during a phone call, as well as through plain old SMS. I dug into it a bit, studied the topic, and realized the data packets would need to be optimized to make transmission practical.

I spent several days experimenting, studying existing approaches, and generating ideas. In the end, a compact format called CJON was born, and it showed pretty decent compression. I published my first article on Habr and built a prototype encoder to convert JSON into CJON and CBOR. It turned into an interesting little product that I will definitely come back to later.
