Julia's biggest success[es] so far?

[NiclasMattsson]

Here’s a short testimony by @Satvik about a commercial success that I bookmarked last year. It’s (probably deliberately) vague about the details but I found it impressive and convincing nonetheless.

Julia's applicable context is getting narrower over time?

We recently added Julia to our codebase, where we’d previously used Python only for 3 years. This was motivated by optimizing a major process that was a key part of our product and cost $15k/month to run. As you can imagine, we had already heavily optimized it in Python. Everything was using numpy and calling C libraries beneath the hood, but besides that we employed many performance tricks that resulted in very ugly and unpythonic code. We had several very talented engineers look at this, inclu…
