    A #RosettaCode contribution for #ATS -- the old insideness of a convex hull algorithm. I decided to do this because I am likely to stick the algorithm within my next Bézier intersection algorithm (which will be coded in Ada using homogeneous geometric algebra, not in ATS using euclidean, but whatever) --

    There is a new #ATS example at #RosettaCode, part of my nascent tendentious series of simulations that show quantum physicists are entirely wrong in some of their beliefs:

    rosettacode.org/wiki/Simulated

    This #ATSlang code is all or mostly free of the proofs and complicated call by reference you often see in my ATS code. You could translate it straight into OCaml or SML. It is a simulation, supposedly impossible, of experiments you sometimes see hyped in the news, but which are stupid.

    Some #RealTime #ObjectOriented programming in #ATS for #RosettaCode. And I mean really #OO, not type hierarchy masquerading as OO. Communicating objects.

    There is no type hierarchy, because none is needed. One can use a closure to connect two objects, as long as the connection is compatible at both ends.

    And there is just one thread, because why in heck would you need two threads, just to read the time on the clock??????

    Another #ATS example for #RosettaCode fans!

    rosettacode.org/wiki/Long_mult

    This is long multiplication, which I have used here to solve two distinct problems.

    The designer of the task must never have realized you could do this in something other than BCD and end up not having a carry ever occur.

    (Yes, nested loops/tail recursions might be slightly faster, but in #ATSlang are likely to be wordier and not enough faster to matter. Though for this particular problem you could use the for-loop notation with relative ease.

    Whether nested loops or one overall loop is simpler to write depends on the language and style.)

    Sure, one can use SDL2 or whatever to draw lines, and, sure, these figures have "aliasing", but the tasks call for aliased figures. (I already did antialiased lines in ATS for a different task.)

    I have started a set of #pixmap = #bitmap manipulation tasks (since when do we pretend a color image is a ‘bitmap’?) with an #ATS contribution to the very first of the tasks:

    rosettacode.org/wiki/Bitmap#AT

    I went back to doing things at a low level, which my readers surely will appreciate. So the code is lengthy, given what is being done.

    And safety is important, so notice that if a ‘load’ fails you still get valid image data (an image filled with one color).
