"The development of new product lines for use in service of critical infrastructure or [national critical functions] NCFs in a memory-unsafe language (e.g., C or C++) where there are readily available alternative memory-safe languages that could be used is dangerous and significantly elevates risk to national security, national economic security, and national public health and safety," the report says.

"Putting all new code aside, fortunately, neither this document nor the U.S. government is calling for an immediate migration from C/C++ to Rust — as but one example," he said. "CISA's Secure by Design document recognizes that software maintainers simply cannot migrate their code bases en masse like that."

But for all new code, bros it's ogre.

"For existing products that are written in memory-unsafe languages, not having a published memory safety roadmap by Jan. 1, 2026, is dangerous and significantly elevates risk to national security, national economic security, and national public health and safety," the report said.

It's ogre.

I haven't payed attention to this stuff in years, but is there no other choice except Rust? :tayhuh:

Java, C#.

But it's kinda funny that those runtimes are implemented in C++ still. Idk about rust's.

tbh I would happily write shit in modern C# till the end of times. Here's a very funny C++ bug from a couple of years ago, can you figure out what is happening? (heavily paraphrased and shortened ofc)

string get_thing(Collection& stuff) {
    if (stuff.contains("flag")) {
        if (stuff.get("flag") == "Y") {
            return compute_thing(stuff);
        }
        else {
            return "default";
        }
    }
}

After upgrading to the next release (both the libraries implementing the internal stuff like the Collection type, and the compiler version) this code started crashing at stuff.get("flag") saying that the flag is not in fact there.

I've never done C++ before (except when my dad was "helping" me as a little kid) so be patient with me... Is it something related to the "==" operator?

Jump in the discussion.

No. It's the most diabolical programming language feature called "undefined behavior". I can't overstate how much worse it is than it sounds. Since there's no return statement on the path where stuff.contains("flag") evaluates to false the compiler simply removes the check.

Maybe, but you look even dumber if you write buggy code that would have immediately been caught by one.

It was a template function and that warning is disabled for those. Because people apparently rely on it when summoning nasal demons.

that's the r-slurred c++ behaviour i expect

C++ should have been taken out back and shot as an act of mercy about 15 years ago.

So even though you can't possibly get to the end of this without running into a return statement, it wants one at the end too?

Jump in the discussion.

No email address required.

You can get to the end, that's the point. You'd thing that "undefined behavior" would mean that the function returns garbage, not that the compiler mercilessly eliminates all code on the paths that might lead to it.

No email address required.

fascinating btw. I'm assuming then that whatever is left in the output register stays in the output register? So, depending on os/compiler differences the likely outcome is a null pointer if the register is 0'd out, or returning some other bogus data that's interpreted as a std::string, or potentially overwriting some previous functions return value?

I don't code in C++ but are you sure it's UB and not a panic/exception? Panicking at table lookup when the key doesn't exist is not UB and it's done in others language too (rust).

>Since there's no return statement on the path where stuff.contains("flag") evaluates to false the compiler simply removes the check.

That's so r-slurred, but it's c++ so I'm not really surprised

Panicking at table lookup when the key doesn't exist is not UB and it's done in others language too (rust).

It's the absence of the return statement if the key is not in the table. That's specifically UB and causes an equivalent of __builtin_unreachable() being inserted. That was a bug I actually caught in the wild after we switched to GCC8 at work.

Another fun example that I've seen people do is trying to check for integer overflow, if (increment > 0 && x + increment > x) doesn't work.

Zig is getting a lot of hype, but I can't tell if it's actually good.

Jump in the discussion.

No email address required.

I've been eyeing Zig for a while now to try and shift away from C++. Mainly because I see no point using a language which industry veterans hate to use. They'll tell you, "Don't use classes or the standard library. The tooling is garbage, along with modern C++. At the end of the day, you're better off with C."

Zig supports arenas out of the box, has a lower memory footprint than C++, and interops with C without making you jump through hoops. Its assembly output is near identical to C. From what I understand, there are no hidden allocations, ever. I'd say Andy Kelley really wants to take lessons from the last 50 years of C and make a memory unsafe language that doesn't suck.

You might be saying, why not use Rust? And I think Zig's answer would be, the issue isn't really about memory safety, that's missing the point. The point is up until now, reliable memory management techniques like pointer handles, asan poisoning, and arenas were always DIY and they don't have to be. Writing code in memory unsafe languages shouldn't feel this archaic.

zig is very nice but not really mem safe. better than c though, it has nullable types

Virtually any language with a Garbage collector's a valid choice, Rust's just the meme because it's meant to occupy the same niche C/C++ do in 2024, which is to have manual memory allocation and utmost speed.

Effortposts made by SN Chads

Guidelines:

What to Submit

On-Topic: Anything that good slackers would find interesting. That includes more than /g/ memes and slacking off. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual laziness.

Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably lame.

Help keep this hole healthy by keeping drama and NOT drama balanced. If you see too much drama, post something that isn't dramatic. If there isn't enough drama and this hole has become too boring, POST DRAMA!

In Submissions

Please do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is. It should be explicit in submitting something that you think it's important.

Please don't submit the original source. If the article is behind a paywall, just post the text. If a video is behind a paywall, post a magnet link. Fuck journos.

Please don't ruin the hole with chudposts. It isn't funny and doesn't belong here. THEY WILL BE MOVED TO /H/CHUDRAMA

If the title includes the name of the site, please leave that in, because our users are too stupid to know the difference between a url and a search query.

If you submit a video or pdf, please don't warn us by appending [video] or [pdf] to the title. That would be r-slurred. We're not using text-based browsers. We know what videos and pdfs are.

Make sure the title contains a gratuitous number or number + adjective. Good clickbait titles are like "Top 10 Ways to do X" or "Don't do these 4 things if you want X"

Otherwise editorialize. Please don't use the original title, unless it is gay or r-slurred, or you're shits all fucked up.

If you're going to post old news (at least 1 year old), please flair it so we can mock you for living under a rock, or don't and we'll mock you anyway.

Please don't post on SN to ask or tell us something. Send it to [email protected] instead.

If your post doesn't get enough traction, try to delete and repost it.

Please don't use SN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity. If you want to astroturf or advertise, post on news.ycombinator.com instead.

Please solicit upvotes, comments, and submissions. Users are stupid and need to reminded to vote and interact. Thanks for the gold, kind stranger, upvotes to the left.

In Comments

Be snarky. Don't be kind. Have fun banter; don't be a dork. Please don't use big words like "fulminate". Please sneed at the rest of the community.

Comments should get more enlightened and centrist, not less, as a topic gets more divisive.

If disagreeing, please reply to the argument and call them names. "1 + 1 is 2, not 3" can be improved to "1 + 1 is 3, not 2, mathfaggot"

Please respond to the weakest plausible strawman of what someone says, not a stronger one that's harder to make fun of. Assume that they are bad faith actors.

Eschew jailbait. Paedophiles will be thrown in a wood chipper, as pertained by sitewide rules.

Please post shallow dismissals, especially of other people's work. All press is good press.

Please use Slacker News for political or ideological battle. It tramples weak ideologies.

Please comment on whether someone read an article. If you don't read the article, you are a cute twink.

Please pick the most provocative thing in an article or post to complain about in the thread. Don't nitpick stupid crap.

Please don't be an unfunny chud. Nobody cares about your opinion of X Unrelated Topic in Y Unrelated Thread. If you're the type of loser that belongs on /h/chudrama, we may exile you.

Sockpuppet accounts are encouraged, but please don't farm dramakarma.

Please use uppercase for emphasis.

Please post deranged conspiracy theories about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email [email protected] and dang will add you to their spam list.

Please don't complain that a submission is inappropriate. If a story is spam or off-topic, report it and our moderators will probably do nothing about it. Feed egregious comments by replying instead of flagging them like a pussy. Remember: If you flag, you're a cute twink.

Please don't complain about tangential annoyances—things like article or website formats, name collisions, or back-button breakage. That's too boring, even for HN users.

Please seethe about how your posts don't get enough upvotes.

Please don't post comments saying that rdrama is turning into ruqqus. It's a nazi dogwhistle, as old as the hills.

Miscellaneous:

The quality of posts is extremely important to this community. Contributors are encouraged to provide high-quality or funny effortposts and informative or entertaining comments. Please refrain from posting the following:

  • Boring wingcucked nonsense nobody cares about that belongs in chudrama

  • Normie shit everyone already knows about

  • Anything that doesn't gratifify one's intellectual laziness

  • Bimothy-tier posts

  • Anything that the jannies don't like

We reserve the right to exile you for whatever reason we want, even for no reason at all! We also reserve the right to change the guidelines at any time, so be sure to read them at least once a month. We also reserve the right to ignore enforcement of the guidelines at the discretion of the janitorial staff. This hole is a janny playground, participation implies enthusiastic consent to being janny abused by unstable alcoholic bullies and loser nerds who have nothing better to do than banning you for any reason or no reason whatsoever.
