The signaling in this case is typically a shared atomic though not some OS primitive that a process can wake/epoll/etc on?

What... its shared memory? What is asynchronous about touching a few atomic vars and shared memory (shared pages) exactly? You could absolutely poll on this sort of thing in a non blocking manner, but there is not OS primitive here to trigg

iceoryx2 uses shared memory and is implemented in rust if anyone wants something off the shelf

It’s dead in the water from my perspective. Tied to windows baggage, not actually faster, arm windows apps are… yeah not exactly vast in number.

I’m not seeing the numbers where it blows away the M3 myself, maybe I missed them? Some modest uptick over yesteryears part from Apple doesn’t blow me away.

Leetcode tells you little to nothing about an individual’s actual skill set? I wouldn’t work for a place that required this sort of bs? Imagine if for every job as a carpenter you need to show you can cut wood properly. It’s fucking ridicul

No doubt defense in depth is good, but frankly there's a cost to mpu/mmu (mpu does much the same in terms of memory protection but without the benefit of a dynamic page table...). There's a cost to jump from memory protected

yeah we'll see... the historical evidence is entirely contrary to this
279.
by bfrog 2y ago
The entire premise that you need an MMU is about invalid memory accesses. Safe rust does much the same job with much finer grain and at compile time not runtime where dealing with page faults can lead to some strange loops. No need for IP

Qualcomm has some work to do to build trust. Step one make the docs as easy to get as say the Intel x86 references without a bunch of horseshit lawyer shite. Step 2, actually document the part well enough for third party implementers. Step

Seems like the goal of RTO is working

This seems like the kind of thing that would benefit a great deal from rust usage.

He was right about licenses with compilers as well.

People coming to rust attempting to apply typical OOP terms and patterns are likely to hit walls quickly. There’s are some things that of course look familiar. But it’s not where Rust came from, and it’s not what Rust provides.

Will there be a lunar lake model this fall? I’ll be shopping for sure then

Ah yes another sub language made from c++, every author has their own What we really need is C2 C with constexpr, type traits, and generics… oh wait this exists! Rust, Zig, etc Sadly tool chains for some platforms are proprietary variants o

At an OS level its kind of a sad state of affairs, even on tiny devices the goto solution is an RTOS with threads (they aren't cheap memory or latency wise!) If you look at what things like RTIC and embassy are doing I have to say its

This is the kind of amazing news I come here for. And the kind of hard science real life tech that makes lives truly better. Love it. Thanks hacker news!

This is really neat! I’ll have to take a closer look and see if some ideas could be reused in zephyr’s new elf loading facilities

sadly so much is tied into cmake with all its eccentricities of being a weird custom macro language, hard to see using anything besides cmake unless I stop using C

Most US citizens seem to agree something needs to be done there regardless of political lean? 74% according to NBC polling (surely not right wing crazy land) https://www.documentcloud.org/documents/24172785-230343-nbc-.

This is the FSF situation in a nutshell, gcc has slowly been eroding in favor of llvm and clang because of this. FSF donor listing/sponsorship listing is... spartan at best. Compare this to Linux Foundation and LLVM Foundation, and g

Perhaps Elon should step down? It seems his golden boy image is more than a little tarnished and he’s leaving bodies in his wake in sizable proportions.

Using shared rings of buffers is almost but not quite what io_uring provides? It looks like it takes an io_uring style approach and natively so unless I’m misreading? Have the performance numbers somewhere been validated?

Intel 20a and 18a are the really exciting processes yet to come out from everything reported. It seems like a game of catch up until then.

Microsoft in a nutshell… I swear they offplanered their ux people to the moon where they couldn’t do anything. Or they have no ux people. Or their ux people have no effect.
