> I also took the only subroutine that was actually classified (it did great circle distance calculations between any two points)

Circa 1984 (ish) I was in Australia and we didn't go looking for such wizardry .. it was easy enough to derive Great "Circle" paths about an oblate spheroid from first principals and, if required, weight the problem by wind strength, etc.

I was coding, at the time, for airbourne geophysical surveys at continent scale, so we were also pulling in IGRF models, normalising for diurnal magnetic flux, calibrating radiometric systems for air colum mass under craft | cosmic breakdown gammas from above, and all that jazz.

Was there anymore to your classified great circle code snippet than the correct geometric answer for a "not an actual sphere" .. or was the secret sauce just the exact series terms chosen and the order of computation in order to minimise error and reproduce consistent answers?

( I'm not asking for the revelation of the actual classified details, just curious about shape of the classified hole from the outside )

Evernote was really great for a little while. In 2015, when I purchased my first mobile device, I realized I needed to get up into the cloud, and one of my local-only apps was note taking in Ubuntu Linux. So I auditioned a few apps and decided that Evernote was really nice, and cross-platform, and had plenty of offline functionality. It was good, it had good features that I appreciated, and in fact I used it so heavily for notetaking that it became my de facto password manager. I found that I was recording lots of notes about every account I had (many real-world-related accounts, such as utilities and benefits) and so it was totally logical to just put credentials in there too. Yep, unencrypted!

Evernote really helped during an intensive job search. I could clip the entire job listing to an article on Evernote, and I could refer to the full text later on. I could also add notes to it in any form! Nice!

At the time, I was also using Dropbox for cloud storage. I exited both Dropbox and Evernote eventually. Now I just use Google Workspaces for everything; no complaints.
I wish they included a proper spec sheet for their cpu: SOPHGO CV1800B

I've spent few minutes searching and I don't know, can I use this for machine vision applications? Does it support serial cameras (Csi)? Does it have hardware support for h264(h265 or even better vp9) encoding/decoding? What is the number of Tops of its "vector accelerator"?

I suspect they don't put info like this out front is that it probably is lower than established rockchip chips.

The price is significantly lower too, but for when I need to run embedded Linux I also need video/camera acceleration etc. For devices that don't need a camera/voice interface like a Smart switch, a weather station etc this is massive overkill.

So it is a case risc v being cool, but there is still no clear winning niche for it that I know of.
I’m wondering what kinds of APIs will be available.

It would be a hoot to see people write modifiers for the displayed eyes, to show things like cat pupils.

As for the rest, we’ll have to see. There’s a long history of really difficult problems with 3D/VR/AR, but Apple has more money than some countries, so, if anyone can solve them, they can.

I remember when the iPhone came out. I worked for a camera manufacturer, at the time. One of my employees brought one of them, and I looked it over. One of the things that immediately jumped out at me, was the built-in rear camera. It was pretty limited, with crappy resolution, poor light-gathering, weird depth-of-field, shaky image quality, and noticeable latency, but you could preview the image, live, on a fairly big screen.

People may also remember, that, when the iPhone first shipped, there was no SDK, and the App $tore did not yet exist. No one could write any apps for the phone. The JS Web apps thing sucked (even though many folks now write iPhone apps in JavaScript). Even Steve Jobs couldn’t make developing for iPhone attractive.

Nonetheless, using the device was incredibly convenient. I knew that if they could improve these issues, it would be a winner.

I mentioned it to our marketing folks, and was laughed out of the room.

A few years later, our entire consumer camera division, which had made us billions of dollars, was in the toilet. Even our pro camera division took some serious hits. A couple of major newspapers fired all their pro shooters, and told their reporters to use iPhones.
No, a flight simulator manufacturer, but we ended up not being remotely the only team it bit (for that matter it may have been you guys' mailing list trail we followed to find the kernel tweak to work around it since Red Hat's answer was "yeah don't do that")

By C standards that’s perfectly fine. No crazy macros, just plain old bit-twiddling. The and-not combination is a very traditional pattern for bit masking.
I actually disagree strongly with (part of) this. Having a singular target menu I think is a good design decision (I used OSX in the past, but currently use windows+wsl at home, and linux for work).

Having a singular menu position is consistent. It gives you an 'infinite' Y target...you just slam your pointer into the top of the bar and get menu options, and only have to care about X accuracy.

The persistent menu on minimise, I do agree, is daft. But having a consistent location I think is a good decision. Need menus? Look at the top. Need menus? Mash your mouse into the top of the screen.

The article takes for granted this bizarre assertion that these businesses NEEDED to layoff people this year.

I'd noticed mention of the Readability extension, which no longer exists.
Yeah, this sounds like textbook price discrimination via market segmentation to me. Producers do this to capture more of the consumer surplus value (willingness of some consumers to pay more than others). The alternative is to offer a single model for a price somewhere in between. Without the segmentation the richer / more willing to spend consumers save some money, but some of the poorer / less willing to pay consumers get priced out of the market. With effective price discrimination, the supplier gets higher profits, but there's also some cross-subsidy from bigger spenders to the more thrifty ones, so there's also some progressive redistribution.

Also raises questions on how this is perceived. For example some study said introverts have a higher emotional response from inanimate objects, such as when chatting on the computer.

So could one person perhaps perceive a virtual discussion to be synchronized when it in fact is not?
Meta says its new speech-generating AI model is too dangerous for public release
It's an open model so if you want, for a fraction of the training price, you can fine tune it with adult fan fiction to generate even more adult fan fiction if you really want to.

An open source model allows for that. Compare this to ChatGPT/GPT-4 which are closed and filtered at the API level.

How do you feel about the fact that all your institutional knowledge is now not visible outside of Discord, not indexed and barely searchable?

How do you feel about the fact that the long-term survival of this knowledge is at the whim of a company that is mostly focused on the gaming community and has no vested interest in preservation over longer time periods?

When was the last time you found an answer to a question from an ancient newsgroup or mailing list that's archived on the open web? It happens to me fairly regularly.

(for context, I help maintain a Discord for an open source project and I feel like I'm betraying the web as an ideal - and constanty wish we had chosen differently)

EDIT - I didn't look to see who I was replying to. Simon -not you of all people! I'm less concerned about your specific community than I am about the example you're setting and the the fact you're lending your voice to support a worrying trend that affects the long-term health of open source.
I only looked over your code for a minute but found some stuff I would comment on in a code review.

Comment for a method says "null safe" - why not use an annotation?

A package called "util" is a code smell for me.

Ah, that's fair. If you're running software packaged by others, that might be less well-covered because you'll have to wait until all of the vendors you care about add in that supprort.

If you're developing software in arm64 Docker, I think that case is pretty good today.

I agree in principle; a reasonable spec that doesn't change all the time is what's needed for supporting next-gen browser development (as in inspire a new generation). But that's not what's happening at all; collaborators of github.com/whatwg even welcomed the rejection of HTML profiles/subsets and target device classes when the idea was brought up by MS (to save IE, but still ;)

But the ones responsible for the piece of shit that is CSS are actually W3C, Inc. Not that the bad looks of Google having them by the balls is better than your scenario eg the impression W3C on its last legs receiving money to keep the illusion of a multi-party effort of web standards.

I don’t think their goal is to make something to use along with heavy machinery. I’d say they’re leaving that market for other operators. All their promos (and of almost all their hardware) pitch a pretty consistent crowd.

> It might not be desirable for the Linux team to accept patches for every standalone piece of hardware.

I believe this may warrant an “extended mainline” kernel project that has all those extra modules and that works to consolidate them into the least amount of different variants as possible, all the while providing some continuous hardware testing. It could be maintained in part by the manufacturers themselves who’d need to provide hardware and high quality code at the very least to be able to claim support from this extended mainline.

Sounds like my second business idea for the day. I’d love if someone would run with it.

eBPF seems to be almost exclusively used by the Linux kernel. Are there other uses by other operating systems / environments? And what about WASM?

Can't speak for abseil and tbb, but in folly there are a few solutions for the common problem of sharing state between a writer that updates it very infrequently and concurrent readers that read it very frequently (typical use case is configs).

The most performant solutions are RCU (https://github.com/facebook/folly/blob/main/folly/synchroniz...) and hazard pointers (https://github.com/facebook/folly/blob/main/folly/synchroniz...), but they're not quite as easy to use as a shared_ptr [1].

Then there is simil-shared_ptr implemented with thread-local counters (https://github.com/facebook/folly/blob/main/folly/experiment...).

If you absolutely need a std::shared_ptr (which can be the case if you're working with pre-existing interfaces) there is CoreCachedSharedPtr (https://github.com/facebook/folly/blob/main/folly/concurrenc...), which uses an aliasing trick to transparently maintain per-core reference counts, and scales linearly, but it works only when acquiring the shared_ptr, any subsequent copies of that would still cause contention if passed around in threads.

[1] Google has a proposal to make a smart pointer based on RCU/hazptr, but I'm not a fan of it because generally RCU/hazptr guards need to be released in the same thread that acquired them, and hiding them in a freely movable object looks like a recipe for disaster to me, especially if paired with coroutines https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p05...
I'll die on the hill that James Camerson was also just plain wrong. Multiple scenes in Avatar are done in ways which either fail to take advantage of 3D, or are shot in a way which plays right into it's weaknesses.
I was supporting my argument for hundreds of years of bureaucracy built up.

Reducing support for local councils has been deeply unpopular, but pointing out 32 + 1 local councils for London is overly bureaucratic and long agreed to be inefficient doesn’t connect to that in any way? The actual solution is to get rid of most of them, but a stopgap is to reduce their funding and thus waste.

Statement by the CTOs of seven of the world’s major aviation manufacturers
I'm in the same boat- I just want a simple headset that overlays a big, high-resolution monitor on my normal vision.
The closest thing I know of is the [Simula One](https://www.simulavr.com/), which seems to be a VR "virtual monitor".

VR instead of AR is a dealbreaker for me though- I want AR virtual monitors that overlay the displays on my actual vision. Even VR which uses a camera to pass through to the display isn't really what I want.

My ideal hardware would just be a "dumb" AR display with wide FOV and an HDMI input that just overlays the video data onto my normal vision.

From what I understand a big challenge is the wide FOV though, but I don't know enough about optics to really understand why this is the case.

That sounds very interesting. Would you be able to reference any such exotic data structure and maybe the process of getting to defining it?

EDIT: To be clear, I was not being flippant, I was assuming that there is some nuance to how "assets" is used here that I'm not aware of since I'm not a 3D artist which would make this work novel compared to the work in the demoscene. Beyond being a general purpose asset generator, which is indeed very impressive but not what is being argued here.
As pavlov said, it's readable enough to many (those that understand bitfields).

It's literally current size + (current size/8) + fiddle

( the fiddle is there to prevent a fail to increase for small input (exercise for reader?) )

followed by a mask to ensure a multiple of 8.

The rational would be no floating point ops and all the weirdness that can entail plus the speed of raw shift | addition | mask.

You're correct that it deserves a twice over as the fiddle raises an eyebrow that invites investigation across inputs.

This could also be an AppleTV moment, where it takes a long time to turn into a real product that a lot of people will want. And even then might still not be a new core pillar of the Apple ecosystem.

I dunno. I've had problems with every AR/VR system I've ever tried in the past 20+ years, so I don't know that Apple will be able to solve this one.

But of all the companies who have at least announced products in this space, I think Apple is best equipped to make it happen. If anyone can do it, I think it's Apple. Just maybe not this decade.
