To preface, this is just one person’s attempt to help people save some time and engage with a new language with more reasonable expectations, not a standalone or authoritative source of information. I expect learning about Julia or any mentioned topics to be mostly accomplished by studying other sou…

Rang a bell, which is something Brian Kernighan wrote—rather than resorting to wishful thinking to improve performance by piling on “optimizations,” find a better algo.

If the title promises “frequent myths”, then each section heading should state such a myth (e.g. “Julia aspires to be the last programming language”) and not its negation (“Julia does not aspire to be the last programming language”). Otherwise the section headings become quite confusing.

@Benny It doesn’t look like writing targeted at beginners at all.

I think you should reorder the myths on dynamic typing and multiple dispatch. The actual myth that you’re battling is that many people don’t have a very clear definition of static vs dynamic types in mind. I would emphasize that static types are a property of a program, while dynamic types are a p…

I didn’t expect any feedback after a couple days so this was a pleasant surprise. A lot of what was commented were on my mind, but I ended up leaving them alone because I didn’t think of any good resolutions, so thanks in advance for any help. [image] mgkuhn: each section heading should state s…

[image] Benny: I had “clearing up misunderstandings” before I gave up. FWIW, I think “Clarifying common misconceptions” or “Clearing up frequent misunderstandings” (or some mix of the two) would be perfectly fine. I also agree that repeating the falsehoods as (sub)headings has risks and its …

[image] Benny: I’m not exactly sure what you mean here, but I did have concerns that I was talking about too much that many people would reasonably not know. I did try to simplify it as much as possible, but there’s a point where simplifying it further would result in loose, handwavy phrases tha…

The headings are not myths. They are the counterstatements.

[image] abraemer: one could try to state both the misconception and the correction I think I’ll just do that. It’s just a handful of extra sentences and it’s the part of a listicle that people reasonably pay attention to.

I’m not sure if the promise of an easy transition from Matlab, Octave, Scilab, etc. to Julia is also a myth, but if it is, this other post better describes the challenges faced by Julia beginners than anything else.
