This is a confusing rebuttal, because cars have an aerodynamic design primarily for performance reasons, and Evan is very clear in this article that his primary concern is performance. I think you've misread him.
And yet he doesn't care about type systems, which are largely implemented to help with optimization, you see.
This sounds like premature-optimization to me. Maybe it's just me, but in the apps I write in dynamic languages, the bottleneck is rarely in the language. It's usually in some IO. EDIT: some sentence in the article gave me the impression he was using this for non-math-heavy stuff which is why I said this
There are a lot of reasons to want speed in a dynamic language.
I'm excited by Julia, but I don't think this article makes a very good sell. It's neat that you can dump the generated assembly, but I'd rather see a demonstration of a robust profiler so that I know which functions I need to dump in the first place. I also disagree that the popularity of Node stems from "getting disparate groups of programmers to code in the same language". From what I've observed, it's not that bac…

> Node.js has only a few great use cases where it shines and in the real world, the vast majority of shops have not switched to using it. Of course not. 'Switching' is usually more pain than it's worth, especially if your previous solution works. New start-ups are likely the ones who will be using it, just as Rails took off in the start-up world. Likewise, R and Python are going to continue to be in use in existing p…
In my experience, most people are turned off by using Javascript on the backend of web-development. Your experience may be different, but I just don't think the analogy made in the original article is a very good one.
Or you could use something like Coffee-script from front-to back. It's a very easy eco-system to get into.
Wait a minute! Can you embed Julia into a C program like Lua? Can it interface with complex C types cleanly?? This might be the scripting language I'v been looking for in my side project!
Julia may have just saved my project (which was dying because it needed a good scripting language that was fast)!

Really? My impression is that it's largely correctness.

That's arguable - I hear more people talking about how types reduce bugs in code than how it improves performance. Besides, that's one of the three examples he mentioned, and the the other two are not features involved with said optimisation.
