Oh wow, according to @codetrendr (account should start mirroring soon) #LavinMQ was 🚀 trending on #GitHub two weeks ago? 🤩

For those who don't know: it's a #MessageQueue written in :crystal: #CrystalLang supporting #AMQP 0-9-1 (like 🐰 #RabbitMQ) and #MQTT (popular in 🤖 #IoT).

And it was born at @84codes / #84codes. 🙏🏻

Very cool:

if you're using #VSCode and you program in :ruby: @ruby, :crystal: @CrystalLanguage or 🐍 @Python, then you might want to use @ninoseki's #vscode_extension Mogami, which shows the latest dependencies in #Gemfile, #shards and #requirements_txt.

Keep in mind that #crystalshard checks are only working on #github repos for now though!
