  • Cobol Has Been "Dead" For So Long, My Grandpa Wrote About It

    Jump

  • And COBOL is listed as third-generation on Wikipedia, too.

    I now remember reading about this concept of generations in a book about Ada, it seemed fascinating then but turned out to not be as good as expected 🥲

    Also, Unix Shell is listed as 4GL example. There are SPSS, MATLAB, R, and Wolphram Alpha in the same list of examples, that kind of shows where 4GL went today.

  • Pretty much sums my experience with windows, something you want will either work fine, or be mysteriously broken beyond repair with no apparent reason. MacOS is like that sometimes, too. Linux is not perfect, but it usually allows for a fix to exist.

  • Are we still talking about COBOL?

  • Why I Prefer Exceptions to Error Values

    Jump

  • To be fair, I disagree with all the points author makes, except for performance which is important but may be less important than code clarity in different cases. I am surprised that exceptions perform that well, and I am surprised the author said that compared C++ exceptions to Rust results, but actually did the right thing and compared C++ exceptions with C++ expected first. I thought it was going to be one of those "let's compare assembly to lisp"

  • Why I Prefer Exceptions to Error Values

    Jump

  • Yeah, I shaped my words poorly. What I meant is that errors are sort of equivalent to exceptions, but errors are first class citizens of type system, and this is an improvement over exceptions being kind of independent of type

  • Have you ever worked at large old corporation? Wasting money is a bit of an underestimation on that scale.

    Also, not all banks use COBOL, but the ones that don't are usually much younger.

    Besides, Ada would've been a better example, as it is used by telecoms and seems to be held in high regard, unlike COBOL. The only issue with Ada I heard of is that it's on par with C++ in complexity which is far from being simple.

  • I'm just going to ask, without making assumptions. Have you managed to cut some time to read the article and find an answer?

  • Why I Prefer Exceptions to Error Values

    Jump

  • you never know what code your function or library calls that can produce an exception

    As far as I remember, there were several attempts at introducing exceptions into type system, and all have failed to a various degree. C++ abandoned the idea completely, Java has a half-assed exception signature where you can always throw an unexpected exception if it's runtime exception, mist likely there were other cases, too.

    So yeah, exception as part of explicit function signature is a vast improvement, I completely agree

  • I feel like this will have zero protection against

     c++
        
if (result.isSuccess()) {
    handle_error(result.error);
} else {
    do_something(result.value);
}

    Besides, this is exactly what the comment said about having to constantly check for return values at call site. I think this may be mitigated by some clever macro-magic, but that will become a mess fast.

  • It's used because the ones who use it have enough money to pay for any problems that may arise from it's use, and known problems are deemed better than unknown ones.

    It is a viable model when you have enough money and resources, but a conservative one

  • it's one of the most popular languages used for C/C++ build scripting

    Unfortunately 😅

  • That way we'll just find maintainers went near extinct over time, just like COBOL developers that are as rare as they are expensive. Only Linux kernel isn't a bank, and maybe will not have as much money to pay to rare developers capable of maintaining C codebase

  • Well, as they say, "common sense is not very common", but thinking a bit before rushing in may always do good.

    ::: spoiler about the "quote" It actually should read

    It is sometimes said, common sense is very rare

    as written by Voltaire, it appears, but I didn't know that and only met derivatives of this quote.

  • It's the number of the signal sent, 9 is for SIGKILL. You can send various signals with kill, and depending on how application was made it may react on all signals with dying, or meaningfully process most of them. Afaik, SIGKILL can't be processed by the app, and it always means just that: "die already".

    Checked in Wikipedia, that's about right but there are more details I left out, mostly because didn't know about them, too: POSIX signals

  • No, it's when someone wanted to change docs to say "they" when referring to the user. I don't think it was really necessary, but refusal to do that looks like a statement I don't like.
