This time I review a piece of code by https://twitter.com/sandeepdinesh, from his repo https://github.com/thesandlord/logpipe
The program simply reads from standard input and sends each line both to standard output and a logging service.

To do this we will use Go, the anaconda library by ChimeraCoder, systemd, and ... a free micro instance from Google Cloud Platform that turns out to be free!

This is the second part of CSVQL: https://youtu.be/bcRDXAraprk CSV files are the basic format for data sharing, but they're not always the best way to consume it. So, what if we created a SQL server that reads the content directly from the CSV files in a folder ... all of it in Go? 5 points posted by kenny

Many people have asked me about videos on gRPC, and I decided that before getting into those technical topics it'd be nice to have an intro video to Protocol Buffers (aka protobufs), which are one of the basic technologies at Google, and which is part of most of Google APIs and services.
