This article aims to be the simplest introduction to constructing an LL(1) parser in Go, in this case for parsing SQL queries. It assumes minimal programming competence (functions, structs, ifs and for-loops).
In the past few weeks we’ve rolled out a Go microservice called ‘KIB’ to production, which reduced a huge portion of the infrastructure necessary for Movio’s main product, saving considerable AWS bills & maintenance, significantly simplified our architecture and made our product 80% faster on average. We wrote KIB on a Hackathon.
I’ve written a blogpost for Movio about two Go CLI tools we’ve created, sql and chart, to improve our data tinkering workflow
A chess engine that solves several use-cases that there are no good free online sources for, and a good candidate for AI research or for a backend for chess sites.
I’ve written a blogpost for Movio about our squad’s decision to migrate part of our Scala codebase to Go.
In this blogpost, I describe the most popular tools currently used to diff streams on the terminal, their differences and limitations. Then I introduce a new tool I’ve developed, sd, to address some of these limitations.
