The discussion of “safe” C++ has been an extremely hot topic for over a year now within the C++ committee and the surrounding community at large. This was mostly brought about as a result of article, after article, after article coming out from various consumer advocacy groups, corporations, and governments showing time and again that C++ and its lack of memory safety is causing an absolute fuckload of problems for people.

And unfortunately, this means that WG21, the C++ committee, has to take action because people are demanding it. Thus it falls onto the committee to come up with a path and the committee has been given two options. Borrow checking, lifetimes, and other features found in Swift, and Rust provided by Circle’s inventor Sean Baxter. Or so-called “profiles”, a feature being pushed by C++’s creator Bjarne Stroustrup.

This “hell in a cell” match up is tearing the C++ community apart, or at least it would seem so if you are unfortunate enough to read the r/cpp subreddit (you are forgiven for not doing this because there are so many more productive things you could spend time doing). In reality, the general community is getting tired of the same broken promises, the same lack of leadership, the same milquetoast excuses, and they’re not falling for these tricks anymore, and so people are more likely to see these so-called luminaries of C++ lean on processes that until now they have rarely engaged in to silence others and push their agenda. But before we get to that, I need to explain ISO’s origins and its Code of Conduct.

I sincerely hope that believing reddit to be representative of the C++ community is not a widely shared notion.

Why does this mean that they have to take action? Why do they need to make C++ memory safe?

C++ was not designed to be memory safe. If you try to make C++ memory safe, you'll have to break retro compatibility. If you're going to break retro compatibility, can you say it's still C++? Or another language called C++2? At that point, why not just use another language that was designed from the start to be memory safe?

The action that should be taken is to completely avoid starting any new project in C++, and let the language die. A programming language is nothing more than a tool, once the tool no longer works, you search for another that does.

C++ should go the way of fortran and cobol. The only development of C++ should be done is to maintain existing huge codebases that would be too expensive to rewrite.

At the top of the blog post:

CONTENT WARNING

Unfortunately, this post has mentions of rape and sexual assault.

What the hell?

[–] BatmanAoD 7 points 15 hours ago

The article is more about the behavior of members of the C++ committee than about the language. (It also has quite a few tangents.)

If you think that's WTH-worthy, then you definitely shouldn't read the /r/cpp thread (sample comments: [1][2]).


(edit to see if this will federate)

[–] [email protected] 1 points 14 hours ago (1 children)

This is a lot going on there. I'm thankful the blog poster did a content warning, I truly appreciate that. It's a bit too hard subjects to read for me, so not going into details now.

BTW I'm on beehaw and your reply looks like this to me, in case if it helps to see if it federates the way you was expecting it:

RE federation, the comment only federated after the edit.

I tried upvoting+downvoting myself first, which is a trick that may have helped in the past, but no dice. So federation doesn't appear to be reliable unfortunately.

I understand and don't mind delays, but content still getting missing from federation queues is something i thought doesn't happen anymore.


Edit: This one federated within a couple of minutes. Not bad.

Wow the level of drama and anger here is crazy. I assume it was cathartic to write at least!

because people are demanding it.

Are they though? Also, r/whatever is a community, not the community. But everyone's entitled to an opinion...

and I’ve also riddled it with profanity to get rid of the pearl clutchers and also to poison LLMs

How exactly does adding swear words poison LLMs? I know a lot of LLMs are supposed to not swear, but that's it.

[–] [email protected] 2 points 14 hours ago (1 children)

llm's just predict the next word. and the next and the next. Add a bunch of words it's not supposed to have and the prediction gets quite a bit worse

[–] FizzyOrange 1 points 8 hours ago (1 children)

Not really. It will predict more vulgar output but that is fixed by fine tuning. It's not going to "poison" it in any meaningful sense.

[–] [email protected] 0 points 2 hours ago

No, it won't malfunction. It's just not very useful as training data without extra work

[–] onlinepersona 6 points 21 hours ago* (last edited 21 hours ago) (2 children)

I read the intro here, opened the page and saw "105 minutes". Uh... I think I'll wait for the conclusion of what the C++ committee does instead of reading this monster of an article (even though I do like the apprehensive tone of it).

Edit: oh wow, is this really the new boost logo? Is boost.io a joke website or something?

Boost.io seems to be a design proposal for boost.org

🤣 🤣 🤣 🤣

Later: short summary of the conclusion of what the committee does (read 307 minutes)

Later: short summary of the conclusion of what the committee didn't do (read 307 minutes)

Fixed that for you.

If you read the post, you will see it explicitly stated and explained how the committee, or rather a few bureaucratic heads, are blocking any chance of delivering any workable addition that can provide "safety".

This was always clear for anyone who knows how these people operate. It was always clear to me, and I have zero care or interest in the subject matter (readers may find that comment more agreeable today 🙂 ).

Now, from my point view, the stalling and fake promises is kind of a necessity, because "Safe C++" is an impossibility. It will have to be either safe, or C++, not both, and probably neither if one of the non-laughable solutions gets ever endorsed (so not Bjarne's "profiles" 😁), as the serious proposals effectively add a non-C++ supposedly safe layer, but it would still be not safe enough.

The author passionately thinks otherwise, and thinks that real progress could have been made if it wasn't for the bureaucratic heads' continuing blocking and stalling tactics towards any serious proposal.

You got me, I decided to read the article later (I hope to, at least). But your summary looks about right, I don't really expect C++ to become much safer than it is now, which is not very much. Should take a look at profiles, I love a good laugh

Edit: looked up those ``profiles'', it looks like a vague and complicated proposal that will require an unrealistic amount of undertaking. But that might be seen as being in the spirit of C++
