high performance JSON encoder/decoder with stream API for Golang
...Also, I wanted to build a decoder that could consume an io.Reader of line or comma delimited JSON, in a JIT way. To consume a flow of JSON objects from a TCP connection for example or from a standard output. The same way I wanted to build an encoder that could encode a flow of data to a io.Writer.
An rtl-sdr receiver for Itron ERT compatible smart meters
...Smart meters transmit consumption information in the various ISM bands allowing utilities to simply send readers driving through neighborhoods to collect commodity consumption information. One protocol in particular: Encoder Receiver Transmitter by Itron is fairly straightforward to decode and operates in the 900MHz ISM band, well within the tunable range of inexpensive rtl-sdr dongles. This project is a software-defined radio receiver for these messages. We make use of an inexpensive rtl-sdr dongle to allow users to non-invasively record and analyze the commodity consumption of their household. ...
