  1. Those over-complicated, bloated, borderline-useless and paywalled tools are targeted at Windows users who have no idea about command lines.

  2.  @MK-bs3dq  is Swoole compatible with Laravel?

  3. Is that a Microsoft thing? I use Emacs, which doesn’t do squiggles (though there is probably a module for it somewhere). I don’t even have syntax colouring enabled.

  4.  @maccsguitar  You have to learn to treat comments as an essential part of the code, not some optional extra.

  5.  @rumfordc  No, they are not “optional”, “extra” or “redundant”. They are vital.
    1
  6.  @rumfordc  That’s what I mean by “vital”. Imagine trying to get the program functional without understanding what it does. For non-trivial code, that can be come an impossible task.

  7. Fun fact: “Y-combinator” is a mathematical concept from λ-calculus. It’s a function for creating recursive functions.

  8. Use the GNU “date” command to check: ldo@theon:~> TZ=CET date -d "now" Fri 18 Mar 2022 23:07:59 CET ldo@theon:~> TZ=CET date -d "+ 2 weeks" Sat 02 Apr 2022 00:08:01 CEST

  9. There is a whole website devoted to embarrassing mistakes resulting from entrusting important data analyses to Excel jockeys.

  10. Python has the NumPy engine for operating efficiently on large multidimensional arrays, including sparse ones. With custom operator overloads, you can express complex manipulations in a single line of code.

  11.  @Migoyan  I don’t see any Fortran code in the NumPy source tree. Can you point me at any?
    1
  12.  @vincentgoudreault9662  And not FORTRAN, either.
    1
  13.  @vincentgoudreault9662  If they were originally written in FORTRAN, why change to C? Unless perhaps FORTRAN wasn’t good enough.
    1
  14.  @vincentgoudreault9662  I wonder why, if FORTRAN is such a good language, you can’t find “people good enough” to work in it.
    1
  15.  @vincentgoudreault9662  Why is it not being taught in schools? Does it take more “discipline” to “master” FORTRAN than C?
    1
  16.  @vincentgoudreault9662  What is the point of FORTRAN, then, if you can do the same things more easily in C?
    1
  17.  @vincentgoudreault9662  Wonder why that old “fast” FORTRAN code was recoded into C, then. Have you looked at the NumPy code? Maybe you could offer to speed it up by rewriting it in FORTRAN.
    1
  18.  @vincentgoudreault9662  It is up to you to back up your claim with actual, working code. Otherwise, why bother to make it? We have plenty of such code for C; show us some for FORTRAN, if you can. And if you can’t ...

  19. 5:53 Why couldn’t you just put the -1 inside the square brackets? Because then it would be interpreted as a dictionary key of “-1”.

  20. Would you entrust mission-critical business functions to an OS that can only handle 26 drive letters?
    1
  21.  @adriantrummer6126  Or how about basic office functions like reliable printing, or trusting that the system will not suddenly delete all your files? In other words, the sort of areas where Windows has been spectacularly lacking of late?
    1
  22.  @adriantrummer6126  It happened to others.
    1
  23.  @adriantrummer6126  So you were not really here to argue any kind of objective truth, but merely to bore us with your own personal opinions.
    1
  24.  @adriantrummer6126  But you can’t find anybody else who does.
    1
  25.  @adriantrummer6126  Aren’t Windows users supposed to be in the majority? Yet you know I’m right.
    1
  26. @Adrian Trummer You were the one trying to claim “the majority isn’t always right” ... are you now walking back on that? Yes, they do deliver a better user experience, actually. If only because they are more customizable than the one-size-fits-all Windows interface. You see this in the number of people complaining about limitations of the Windows UI that don’t happen in Linux. And in how Microsoft keeps copying features from Linux.

  27. I basically learn stuff as I need to. And keep things like MDN (and of course the Python docs) in my bookmark list!

  28. Here’s one: are you still using hex codes to specify colours? Or have you discovered the CSS colour functions yet?

  29.  @aoeu256  Tools exist, but they don’t work reliably.

  30. At least you know about LibreOffice, instead of hoary old OpenOffice.
    1
  31. Python has ASGI for Web development. PHP doesn’t seem to have any equivalent.

  32. That logo looks too close to the X11 logo.

  33. Having created your edit list, this is the sort of engine you could use to render out the final video.

  34. Microsoft itself won’t use it for anything important. For example, VS Code is built on Electron with TypeScript/JavaScript.

  35. To me, the app includes both client and server.

  36. Yes, continue with Python. Think of the Excel jocks who get excited by this, until they discover that, to take full advantage of it, they have to learn Python. Or hire someone who knows it. That’s where you come in.

  37. Can a Windows machine be the control node?

  38. In my first job outside of University, everybody had a degree, but mine was the only one in Comp Sci.

  39. If they don’t update their browser, then clearly they are not part of most companies’ target market.

  40.  @goldydog1  Companies are only going to pay attention to customers, or potential customers. No point wasting time and money on anybody else.
    1
  41.  @goldydog1  It’s not “user data” that matters, it’s “customer data”. If they’re running outdated systems, why should they spend money on your product?

  42. Automating a GUI is a recipe for despair.

  43. Variables should not be global by default.

  44. 1:36 Echoes of λ-calculus! See, the thing with JavaScript is, it’s a mix of really dumb things and really advanced things that only CS majors (and LISP programmers) can appreciate. Compare this with PHP, which is a mix of really dumb things ... and that’s it.
    1
  45. But surely it is the site’s own fault for including all that JavaScript bloat -- a lot of which is specifically designed to make such scraping difficult.

  46.  @AyrtonGomesz  Java objects are always on the heap.
    1
  47.  @gmodrules123456789  It’s already been explained: it’s to specify which namespace the name comes from.
    1
  48.  @SimonWoodburyForget  Functions and methods are also objects, with their own memory allocations, in Python. This issue has already been explained, anyway (see above).
    1
  49.  @philipp1717  It’s to distinguish between the two namespaces, one for method names and one for field/class names, as already explained.

  50. Amazing the number of incorrect answers that continue to crop up, even after the correct one has been given.
