Maybe one way to change the rules is to stop writing code that needs big hardware. The old options were C or C++ for speed and efficiency (which are difficult and dangerous) or Python, Ruby, NodeJS, Perl, PHP for quick and easy coding (but which are fat and slow). But we have better options now, better compromises... #RustLang, #NimLang, #GoLang, #CrystalLang ... the legacy languages have become the tools of the oppressor

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. 🙏🏻
