Migrating from Gitter API to Matrix

We have a script that post to a Gitter channel using their API. But Gitter is migrating to Matrix soon, and they will shut down their API. Here is the code for our Gitter API client: #!/usr/bin/env bash source .env curl -X POST -i -H "Content-Type: application/json"

Testing bash scripts

A few years ago, I was looking into the idea of writing unit testing for bash scripts, and that's when I stumbled across a project called bats. Coming from a Perl background, It caught my attention due to its use of the TAP protocol (Test Anything Protocol). However the opensource

RFC 862 (echo) in PHP, Part 3: From stream to socket

So, in the previous two instalments [1] [2], I've wrangled together a basic echo server over TCP and UDP respectively. Before merging both code so we have a server that fully implement RFC 862, we need a wee bit of... Refactoring To explain the main motivation, we need to come

RFC 862 (echo) in PHP, Part 2: UDP mysteries

In my previous post, I've implemented an echo server functioning with the TCP protocol. However the RFC indicates that echo should work with both TCP and UDP [1]. When I implemented the TCP version I consider two different sets of network functions in PHP. the stream_socket_* set and the

RFC 862 (echo) in PHP, Part 1: TCP fun

A self-contained server implementation in PHP (8.1) of RFC 862 (echo). That old (1983) RFC describes an IP-based client-server application where the client sends data to the server, and the server returns the same data back to the client (hence the name "echo"). It used to be

Migrating from Octopress to Ghost
