Readit News"So in the fall of 2019, the SoniKube team based at Hill Air Force Base in Utah set out to get Kubernetes running on an F-16 jet."
Am I wrong for being horrified by this statement? This seems like a lot of added complexity where you want minimal complexity. Then again, can't say I've ever tried to run a container orchestrator on a F-16.
This seems like a slippery slope - I think I'd prefer waterfall to a MVP driven workflow for this kind of stuff.
I'm guessing this deployed on a secondary computer, not on any flight-critical computers; no way it would have passed airworthiness otherwise (even in a demo). As a result, the worst that could probably happen would be the pilot having to power-cycle the secondary computer.

I don’t get why would anyone carry that much crypto currencies on their laptop. Fake story or crooks ?
Never attribute to malice that which can be explained by incompetence. A small-ish exchange, run by a small number of developer-employees, with limited computing assets. I can easily see someone making the argument that moving cold wallets to an encrypted, offline company machine would (1) free up resources that could be used elsewhere and (2) would make a less obvious target for hackers. Follow that up with no backups -- because let's face it, most individuals and probably a lot of small businesses have no backups -- and voila: you get a bus factor of 1.

Thanks for pointing this out.
Can you give an example of the strncpy problem?
Also is there a precaution programs can take to use memset more safely?
Replace strncpy and strcpy altogether with calls to snprintf. It takes a fixed buffer size, terminates correctly with the null character, and safely does everything strncpy does and more. It's a POSIX standard, so it should be portable to most systems too.
And yes, maybe it'll impact performance. Worry about that _after_ you profile your code and have the numbers to show it -- I'd bet good money that 95% of developers will never need to worry about it.

Why is open() in fcntl.h and close() in unistd.h? Why does bcopy go src,dst
I don't know about the rest, but open(), close() and bcopy() are not in the C standard library. They are either POSIX or Linux specific. The C standard library functions for files start with f e.g. fopen(), fclose().
On a tangential topic, I don't know of a good reference for exploring what is included in the standard library.
The classic book The C Programming Language covers most, if not all, of the standard library. The whole thing can be found in an appendix. Admittedly reading an appendix isn't normally the best way to learn about something, but the library is so small and the amount not already covered in the text is even smaller so it wouldn't take long to skim. Of course it doesn't cover Unix-specific functions, like the unistd.h header; for that, I recommend Advanced Programming in the Unix Environment.
I'd add that The C Programming Language should be seen as a tutorial (albeit an older one that no longer is fully up-to-date in best practices, in my experience) that can serve as a reference in a pinch (it skimps a bit on the corner cases if memory serves). Advanced Programming in the Unix Environment, conversely, should be seen as a reference book with fantastic examples and discussion on error handling -- yes, you can use it as a tutorial, but it's a tad dense and you'll likely never need a lot of it.
tonysdg commented on Ask HN: What should a systems/low-level software engineer know? · Posted by u/avrmav
I don't do embedded systems, but as a self-respecting software engineer, I am intending to develop proficiency in C/C++ over this next year. Does anybody have any recommended books/courses/projects?
A quick word of warning: be sure to treat C and C++ as two completely separate languages that just happen to have similar syntax. Yes, you can use C++ as "C with classes" (I and many others sure have at times), but you're doing yourself a disservice most of the time if you do.

> 48% of wager earners had net compensation less than or equal to the median wage
I'm surprised. I expected that 50% of wage earners would make less or equal to the median wage. If for no other reason than the definition of median.
Uh, are you thinking mean? Median is lining up every salary, counting to N/2, and selecting the number you happen to fall on.

Is there a reason no one has built a Cygwin-like environment for iOS yet? As in, is it because (1) it's time-consuming, (2) it's tricky, or (3) Apple won't allow it on their App Store?

Mom: "There are starving kids in China, eat all your food!". Thanks Mom; kids are still starving there, and now America is fat. --unkown comedian.
I was told, as a kid, that it was rude to not eat all the food put in front of you, especially at other people's houses. Other parents would comment on how polite we children were for clearing our plates.
I know that Allen Sherman did a version of that joke in his "Ode to Fat People" :-)
> It's the same with Applebee's, Chili's etc. at one point all these places were decent to good before corporate greed and mismanagement steps in and starts selling over-priced sugar cocktails and appetizer specials. It's no longer about providing good food and atmosphere to families but about extracting maximum value from a customer engagement.
There needs to be a single catch-all phrase for this type of process, which (I think) we've seen more and more regularly in recent years. We see it in physical businesses, and it's also probably behind the huge shift to subscription-based services online. My interpretation is that it's essentially the capitalism that we've had for decades, but taken to ever-greater extremes. It seems to be rooted in America (and indeed, arguably behind a decent proportion of America's increasing woes) but is gradually infecting Europe too.
Whenever I see examples, I think of /r/latestagecapitalism, or "hyper-capitalism" but I'm not sure these terms would be widely-enough understood to be helpful in discussing or explaining the phenomenon.
