  • There were breaking changes between C and C++ (and some divergent evolution since the initial split) as well as breaking changes between different releases of C++ itself. I am not saying these never happened, but the powers that be controlling the standard have worked hard to minimize these for better or worse.

    If I took one of my earliest ANSI C programs from the 80s and ran it through a C++23 compiler, I would probably need to remove a bunch of register statements and maybe check if an assumption of 16-bit int is going to land me in some trouble, but otherwise, I think it would build as long as it’s not linking in any 3rd party libraries.


  • I think the thing with C++ is they have tried to maintain backward compatibility from Day 1. You can take a C++ program from the 80s (or heck, even a straight up C program), and there’s a good chance it will compile as-is, which is rather astonishing considering modern C++ feels like a different language.

    But I think this is what leads to a lot of the complexity as it stands? By contrast, I started Python in the Python 2 era, and when they switched to 3, I was like “Wow, did they just break hello world?” It’s a different philosophy and has its trade-offs. By reinventing itself, it can get rid of the legacy cruft that never worked well or required hacky workarounds, but old code will not simply run under the new interpreter. You have to hope your migration tools are up to the task.


  • Storm surges can be insane. I’ve never been in a hurricane, but have witnessed the aftermath. My parents had some property in coastal Mexico that got hit. When we got there to assess damages, the town’s main street was essentially a giant sand dune over 2 storeys tall. The surge had basically lifted the entire beach and dumped it 2 blocks in. The town square was likewise covered in sand with all sorts of debris sticking out of it. And by debris, I mean stuff as large as a fridge.

    (Regarding the property, we kind of lucked out. About a year before it hit, a hotel went up between the house and the beach, which blocked the view but had a major silver lining in terms of protecting all the houses behind it from the worst of the storm. And then speaking to the hotel owner, he said he’d spent a small fortune to build a giant concrete foundation that stretched almost a city block’s length under the beach. People thought he was insane to do that, but it was literally the only waterfront building still standing, so he clearly knew what he was doing.)


  • I haven’t done so personally. A lot of my old activity had to do with helping people with programming questions, so if it’s still useful to someone on occasion, I don’t feel inclined to remove it.

    I left reddit a little over a year ago now, and I don’t really care about what goes on over there. I made my statement of displeasure by simply ending all activity on the platform. I figure whatever legacy I left will eventually descend into irrelevance without my having to physically delete it all. At this point, that just sounds like work.



  • The thing about the MPW Shell is it was sort of the only game in town if you actually wanted a command line with the classic Mac OS. (There’s an awesome little emulator called SheepShaver if you ever want to explore it btw.) Well, I suppose there was A/UX. I thought it was a miracle when that came out. You have to realize in those early days a good chunk of the operating system itself was actually baked in to ROM. (You had to do desperate things to squeeze a GUI out of such limited resources as existed back then!) So to this day I have no idea how they managed to spin off a 'nix despite that.

    Anyways. I wonder, if you made some sort of template format today, to what extent you could write some sort of conversion tool that would scrape a man page or whatever to rough it in and then you could tweak it to get what you want? man pages aren’t super standardized in their format I guess, so it’s probably more trouble than it’s worth. I like to use Python’s argparse when rolling out scripts myself, and its --help format is pretty rigid given that it’s algorithmically generated. Might be more plausible with something like that? I had a quick look just now to see if you can drill down into the argparse.ArgumentParser class itself to pull out the info more directly, but it seems a rather opaque thing that doesn’t expose public APIs for that. Oh well…


  • This reminds me of something from my ancient past. Back in the early-ish days of Apple, there was a development system called MPW (Macintosh Programmer’s Workshop) which included its own little kludgy shell.

    The weird thing about it though was while you could enter commands on the command line like in any shell, you could prefix them with the word commando (presumably a portmanteau of “command” and “window”) and this window would pop up showing various buttons, checkboxes, etc. correponding to command line options. When you ok’d the window, it would generate the command line for you.

    I’m rather hazy about how all this worked, but I think there was some sort of template language to define the window layout if you wanted to add commando support for your own tool? And presumeably, as you say, you could restrict what’s possible with the window interface as you deemed fit?


  • You mean like the comment fields we’re using right here on lemmy?

    As others have pointed out, it’s usually some markdown that’s embedded within the text. Lemmy is using a format that’s actually called “markdown” if I’m not mistaken, or a slight variation/subset thereof.

    I’ve gotten used to the double-star for bold and what not to the point that it annoys me when some message client or whatever doesn’t support it. I share code snippets with people fairly often, and the code markdown is particularly useful to maintain its legibility.


  • I started in C and switch to C++. It’s easy to think that the latter sort of picked up where the former left off, and that since the advent of C++11, it’s unfathomably further ahead. But C continues to develop and occasionally gets some new feature of its own. One example I can think of is the restrict key word that allows for certain optimizations. Afaik it’s not included in the C++ standard to date, though most compilers support it some non-standard way because of its usefulness. (With Rust, the language design itself obviates the need for such a key word, which is pretty cool.)

    Another feature added to C was the ability to initialize a struct with something like FooBar fb = {.foo=1, .bar=2};. I’ve seen modern C code that gives you something close to key word args like in Python using structs. As of C++20, they sort of added this but with the restriction that the named fields have to come in the same order as they were originally defined in the struct, which is a bit annoying.

    Over all though, C++ is way ahead of C in almost every respect.

    If you want to see something really trippy, though, have a look at all the crazy stuff that’s happened to FORTRAN. Yes, it’s still around and had a major revision in 2018.




  • Falsehoods About Time

    Having a background in astronomy, I knew going into programming that time would be an absolute bitch.

    Most recently, I thought I could code a script that could project when Easter would land every year to mark it on office timesheets. After spending an embarrassing amount of…er…time on it, I gave up and downloaded a table of pre-calculated dates. I suppose at some point, assuming the code survives that long, it will have a Y2K-style moment, but I didn’t trust my own algorithm over the table. I do think it is healthy, if not essential, to not trust your own code.

    Falsehoods About Text

    I’d like to add “Splitting at code-point boundary is safe” to your list. Man, was I ever naive!



  • Ah so it’s not only Tkinter then. Interesting. Maybe this is one of the reasons why Python-specific GUIs like Kivy came about? When I first started learning Python though, I came under the impression that Tkinter was the “official” Python GUI with privileged status in the standard library, so I started there and was surprised at how it actually doesn’t play all that nice with the language.

    Oh well. I’m glad OP brought it up because I’m sure everyone who’s tried to write a GUI in Python for the first time hits this before long and has that same wtf moment. :)
