Uh-oh, this is sooo important, some title on the Internet is wrong ! If I read it correctly, the same app, compiled from the same code, for the same OS, but different CPU architectures, exhibits wildly different memory consumption for the

Well, for what it's worth - and as mentioned by a sibling poster - most verbs, and certainly all arithmetic operators, obey a few simple rules for determining which behavior you'll get. I should have noted this, before I started w

I think this is pseudo-code? `flatMap` and `=>` for lambdas look like Scala, but there are no array literals using `[]` there. Assuming you mean Scala-like semantics, your second example wouldn't work at all: scala> Array(A

> without the ambiguity There's no ambiguity! In J, all (with some exceptions) operations work on arrays, period. `1 + 1` is not an addition of two scalars, but instead of two arrays of length 1. As I mentioned, you can have scalars

Unfortunately, I have no idea about the implementation and what optimizations are done in J or APL for which operations :( I know that there are hardcoded "fast path" expressions (particular combinations of operations) which have

No, an array language is one in which all the built-in operations are applicable to arrays. Take addition as an example: 4 + 4 8 In array languages the same operator can be used for arrays; or equivalently you can say that

Both are valid, and were the only ways of initializing objects before C++11, I think. Brace initialization has an advantage in that it allows you to initialize compound values, like containers and structs, even if they're nested:

That's actually what pattern_tap's tap macro expands into :) See: https://github.com/mgwidmann/elixir-pattern_tap/blob/master/...

I think you mean `with`, not `where`? Yes, it helps a bit in some cases, but it's not a replacement for a pipeline - mainly because you'd need to name your intermediate results and "thread" them through the calls yoursel

I was very, very disappointed that the `tap` macro has nothing to do with pattern_tap: https://github.com/mgwidmann/elixir-pattern_tap Basically, in Elixir pipelines are not very friendly to simple destructuring: if a

No! Eiffel should be the default OOP language for any kind of course. Being forced to think about pre- and postcoditions and invariants by the language is a really good thing for beginner programmers. While the syntax is somewhat verbose

Elixir's stdlib is great. It's small, based on a just a handful of concepts, but thanks to how powerful the concepts are it covers a lot of use cases. Every module contains pretty much everything you'd ever need to work wit

Wow, I missed its introduction. Nice. On a cursory glance Celery doesn't make use of it yet, unfortunately.

And pay in memory for that luxury: when using lots of complex libraries (like in ML) the Python process can eat quite a lot of RAM.

qt-console is great, but it's not a notebook, ie. you don't have cells you can go back to and edit. It's more of a classic console, with great readline emulation and ability to display images easily.

Worth noting that org files can also embed images inline. Unfortunately, I don't think it's enough to attract new users: images are non-interactive, you can't embed any other media, you have to pop a separate window to edit c

The second option seems much more convenient - I didn't know you can do that!

D is garbage collected language. I've spent the past weekend writing some toy programs in D, and it was very pleasant experience, mainly because of the GC - I didn't have to think about allocating arrays or strings, I could just u

I don't disagree, but "simpler to use" and "easier to read" are almost orthogonal things :)
