Yes indeed. While Julia does generally eschew the "model.fit(X,Y); model.predict(new_data)" style, it's not because it's functional, it's because it's dispatch-oriented , which is arguably a superset of class-

While you have a valid perspective, the HN guidelines [1] do specifically ask us to assume good faith. [1] https://news.ycombinator.com/newsguidelines.html

Composability via dispatch-oriented programming, e.g. [1] It also pretty much solved my version of the two-language problem, but that means different things to different people so ymmv. [1] https://www.youtube.com/watch?v=kc

On top of that, Julia's non-lispy surface syntax has a perfectly valid s-expression representation that can be displayed with `Meta.show_sexpr`, and for which you could hypothetically enable a repl in only a few lines (e.g. [1]) [1] h

I also started in Matlab + C, and didn't personally like Python very much, but wound up liking Julia after a bit of adjustment. Still a work in progress, but I've written up a few of my lessons learned in the process [1] in case t

On that topic, I'll throw in a shoutout to Cormullion's excellent JuliaMono font [1,2]! Typing certainly does add more friction between u and µ than a chalkboard would, though it is perhaps also notable that mathematicians seem to

If you need to run small scripts and can't switch to a persistent-REPL-based workflow, you might consider starting Julia with the `--compile=min` option. If you know which packages you're going to need, you can also reduce startup

Honestly you were probably fine the first time, given that you can easily disable the GC, and that it's really not that hard to entirely avoid generating garbage (in which case the GC generally wouldn't have been triggered even if

You can just turn off the GC with `Base.GC.enable(false)`

There are a few tricks to getting Julia to be actually fast, and while it's not hard per se if you know them all (at least for numerical work), it's definitely not trivial. IMHO, you really have to embrace dispatch-oriented prog

Ah yes, Python, the famously statically compiled general-purpose programming language :p More seriously though, just because some language may be considered "general purpose" doesn't mean it's the best language for eve

I think the main reason they stopped referencing that claim is that "two-language problem" means too many different things to different people. But yes, real static compilation would be great.

Hmm, good question. There is generally expected to be plenty of decomposition (or in biogeochemical speak "remineralization") happening any time you have enough organic carbon around (and enough of a chemical potential gradient be

As a geologist, we can definitely have an unusual idea of what counts as "fast" :) That's a good question, I would say if anyone found fungi before the GOE that would be a big surprise. Finding them after the GOE makes sens

I don't think that's particularly what's going on. I think it's more just that Julia has a relatively small but incredibly zealous group of users. If Julia solves your personal version of the two language problem, and es

While the underfunding and collapse of the observatory is a tragedy, I think it is perhaps less surprising in the context that much of the original political will behind the observatory was motivated by potential military applications, whic
