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 non-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:
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 real them at least once a month. We also reserve the right to ignore enforcement of the guidelines at the discretion of the janitorial staff. Be funny, or at least compelling, and pretty much anything legal is welcome provided it's on-topic, and even then.

C is still useful in some embedded contexts where you don't want to bring along an entire C++ runtime but yeah that's about it.

This feels less and less common, no?

It is. People tend to focus on cost improvements with high-end hardware but the same is true of low-end stuff, actually the effect is probably felt even more there. Realistically there's just little reason to have extremely weak microprocessors anymore. You can get something that can run C++ just fine for very very cheap and with low power draw. There are obviously still some specialty applications where you run on a tiny microcontroller with 128 KB RAM (for example) but that's become less and less common.
I just checked and you can buy a Raspberry Pi Zero 2 W for $15. That's a full butt computer that runs Linux with 512 MB RAM, a wifi chip, various connectors (including mini HDMI and video output) for $15. Obviously a major engineering firm would be designing their own boards and stuff and not using this but that's just an example for how cheap low-end microprocessors are these days.
tbh at this point I think most of the embedded systems that are only running C and not at least C++ are doing so for legacy reasons.

I'm seeing rumblings of Rust being popular for embedded too but clearly that'll take another five years to be really established.
But yeah, I remember the cool HN post of a guy finding a cheap enough chip to run Linux on for his business cards.

I actually really like Rust and hope it takes off in this space. The community is
garbage but the actual language and ecosystem are good.
I haven't worked in embedded development for many years, but even when I did, the newer hardware we were rolling out was like 20x more powerful than what came before, and cheaper. It was actually kinda annoying because they figured with the substantially more powerful microprocessor, they didn't need any dedicated chips to run the serial buses. Works fine in practice but it means if you have to debug anything on the board, every time you hit a breakpoint (even a conditional breakpoint that misses) it fricks all the serial connections up. Made debugging a bit of a pain.

Any opinion on the Zephyr RTOS?
Kind of funny that it’s C when we were talking that becoming less and less popular but it seems to have a really good build system.

Sorry no, it's been many years since I've worked with an RTOS. I had to look up a list of them to find the one my old job used, it was ThreadX. It seemed fine, at least while I was there I didn't uncover any bugs in the RTOS so that's about as good as it gets. All the boards it ran on were custom/proprietary as well so I doubt any of the free ones would work right out the box.

Makes sense. It definitely seems like a “good rtos” would be silly with modern chips if you can just run friendly Linux![:marseyshrug: :marseyshrug:](https://i.rdrama.net/e/marseyshrug.webp)

Yeah, it really is - I work in embedded and the hardware I'm working with is powerful enough that we can easily use modern C++ and not care. The efficiency gains (whether in execution speed or memory usage) are so small they're not worth the trade-off in developer time.

When I don’t use C I use Go or, if really lazy, Python

Python is just so cozy
I use it for the vast majority of my personal projects since the data sets I'm working with aren't large enough to need better performance and they aren't complicated enough to require static typing.
