Is there an argument for ambivalent function definitions other than "keyword" recycling (possibly in a mnemonic fashion)? I hadn't seen Dzaima's APL, thanks! I like that he made a processing binding; APL always seemed li

So if you have odddouble.m with function y=odddouble(a,b) y=2*x+1 endfunction you can do >>> h = under(@(x) 1/x, odddouble) >>> h(3) ? If so, yeah, I agree you can implement under in m

What on earth are you talking about? If I add `def bar...` to a file foo.py in my PYTHONPATH, it does not suddenly become available in my interactive session, I need to import it first. Further if I change foo.py even importing it again in

Matlab is much lower friction than python. You write a function, using nice linear algebra syntax. Already python is worse: you do a bit of import boilerplate and write linear algebra in a gimped notation. You call the function. Not so in

I have used matlab quite a bit in the past, but not the symbolic math toolbox: can you make a "normal" function definition symbolic retroactively? I thought you need to define the function explicitly as symbolic to start with, or

Here is toy example: I define a function f(x):=1+x 2. J will automatically work out the inverse for me, as you can see below: f=:(1+*&2) f 1 2 3 4 3 5 7 9 (f^:_1)f 1 2 3 4 1 2 3 4 (f^:_1) 1 2 3 4

If you think APL is less expressive than Matlab, you probably haven't really grasped it, IMO. Having said that, Matlab is optimized for manipulating matrices and replicating the notation of normal linear algebra and has excellent imple

Not being overweight is nowadays a prime status marker, so you can absolutely show it off! Once you start shaving off 4g at a time, it's probably time to switch to gear though.

Only garbage like autotools or CMake generates Makefiles, all remotely sane build systems (including the various bazel/blaze derivatives) do away with make, which even sucks as a low level abstraction.

Ugh, sorry, I misread that. The workaround I would recommend on iOS is just turn javascript off in Safari and install another (Safari-skin) browser like Chrome for the times when you need javascript -- or vice versa, depending on what your

This is why I qualified with "general-audience" -- I have no doubt that different industries/companies etc worked out vocabularies to optimize costs, or even that there were some common shared codes. But did the vestigal tele

China does not need random US engineers. It needs a comparatively small pool of people who have the specific know how that China currently lacks and it can probably afford to pay them some large multiple over the US market rate. Why would a

C++ completely dominates games, browsers (and a few things you don't list, such as competitive programming). It is certainly not marginal in the other areas you list either, but were do you get the weird idea that most operating syst

Yes? If you write zero or low allocation code in Java you pay a price for working against the language and you also lack several tools for writing fast code that C++ provides you with (as well as a bunch of useful abstractions), but your de

Isn't it 1000MB/s now? Anyway, a decent consumer grade 500GiB SSD that will give you ~5GiB/s is in the ~$100 ballpark. If you take an io1 or io2 volume and crank up the IOPS you will get at most 1/5th of that throughput,

You know, hedge funds can afford to hire, and in fact in many cases do hire, good programmers. So not every financial institution that uses java does so because its programmers suck.

Debatable. Java's dominance in the data engineering space rests a bit on clay feet: it's unsuitable for scientific computing in a number of ways: for example you can neither write fast nor clean numerical code in java and it does
