(This is meant to be the first entry of a series which will cover individual points more in depth. We’ll see how that goes.) We’re the tech industry. We have ideas. We have ideas all the time. And we’re used to turn our ideas into applications. So, how does it go… here’s the back-end component… here’s the front-end component. We’ll write the former in Python, or perhaps JavaScript, to optimize for prototyping. After all, we have so many ideas, we need the ability to iterate quickly. Sprinkle in a few dependencies, that will speed us up. Oh, and let’s use ChatGPT and Copilot, we’ll be even faster. Oh, and performance, yeah, performance: microservices, Kafka, Redis, Kubernetes… we’re now ready to scale up. Oh, Sentry, Prometheus and Grafana, too, where would we be without ’em? For the front-end, we’ll write a website, and for mobile, Electron. Oh, wait a second, we need to make money and to fidelize our users! Let me see… ads, tracking, and good reasons to revisit our app, perhaps a little NFT here, gamification… alright, we should be good. Three… two… one… and we have shipped v1! Also, the world is burning. Perhaps it’s time we revisited how we do things?

Credit While I’m the author of this blog post, 99% of the work was done by Nicolas B. Pierron. So far, my role in this project has largely been to play the wise old advisor, nodding and smiling mischeviously whenever Nicolas started exploring new ideas, and emitting cryptic comments in Reverse Jedi Notation. A few months ago, we published a short (and mysterious) blog post in which we mentioned HolyJIT, an early research project towards a novel approach to writing JITs. In this blog post, I would like to detail a bit more the ideas behind HolyJIT.
