I had the crazy thought that drones ladden with deliveries could dispatch from the top of a central tall structure (like a skyscraper or antenna), take advantage of the height differential to efficiently glide toward their delivery destination, and then make their return with less weight to carry. Probably very few locales where this could make sense compared to automated sidewalk deliveries like Starship. The speed of the delivery could be astoundingly fast though.
This really isn't new. It looks like instead of treating the "Neural Engine" as an I/O device like the GPU, it's accessed as a coprocessor. It makes sense for them to only expose their functionalities through libraries as the underlying hardware implementation will go through changes in the future. After all, does, say, Nvidia, document their GPU's ISA?
Slightly off topic, but I recently went through my most challenging interview cycle and for the first time in my life I did a lot of interviews that I was not hired for. It was very exhausting and I was pretty down about it for several months (luckily I was employed still). Most recruiters I worked with ghosted.

I interviewed at one of the big companies and did not get the job, but I remembered one of the hiring managers I met during the interview process and followed up with them on LinkedIn and ended up getting another interview for a similar role and got that job.
I think might work well, at least until the "hot" part of your dataset exceeds the available memory in the cache, unless you made the cache distributed and sharded.

This doesn't solve writes. I guess a writer will write to a memory buffer and only flush to S3 when a block is complete; but that wouldn't work in a multiprocess/multi-node environment if they can't share memory buffers.
> it mostly false positives only for dark-skinned people.

Dunno what the technical reason is, but if there was one, I bet it went something like this:

v1: sales 'engineer' says: "Our FR product works great on light skin but terribly on darker skin so we've largely disabled that" and made zero sales.

On v2 (version2 or vendor2), they just dialed up the acceptable false positive rate, said "ya, it works on everyone, no problem!" and sold sold sold!
We have worked closely and transparently with Apple over the past few months not only on the product definition and platform design, but also on multiple architectural decisions for this offering. Many a times - even though not apparent in those moments (but only in hindsight) - Apple has nudged us in right directions that aligned with their future plans. Granted - it's challenging to keep up with the pace of both Apple and AWS - inadvertent regressions do get introduced with certain releases, but we're building mechanisms to catch and jointly remediate them early. Ultimately, both Apple and AWS are excited about this offering, and share the vision of bringing AWS benefits to all Apple developers. We only expect this collaboration to further deepen going forward.
Intel's compiler is basically free for plebs but not for datacentres.

LLVM and GCC are good enough (brilliant, even) for general purpose compilation, but for a (say) supercomputer which is guarded by guns having Intel on the phone can be worth it.
The Dex authors are also core Autograd & JAX authors, so they're not unaware of the benefits of the dense Numpy-style APIs. The challenge is that many numerical kernels and algorithms are just not easily or naturally expressed in this vectorized language. (Think sparsity, irregular access patterns, control flow, etc.)

Current languages, runtimes and hardware currently force most work into this dense, rectangular, vectorized style to achieve reasonable performance, but we would like our ideas to not always remain stuck in this "rut" [1]. Dex is one exploration of how we can improve expressiveness and generality while still allowing for performant compiled artifacts.

I'm definitely not knowledgeable enough in this area (old video game implementations), I was referring to the FPU on the 486 (386 didn't have one), it seemed to me that it might be a useful thing. Interesting it is all fixed point math in Doom.
> Sometimes I don't - that task falls through the cracks.

That line to me is unacceptable. Your(recruiters) job is entirely dealing with people, no coding, no architecture, no design mockups, no capacity analysis or quality testing.

The fact that you cannot even get the people portion right means there is alot of recruiters that should not be in that position. I get that the company itself may be somewhat to blame but not getting back to a candidate should be an offense similar to an engineer pushing untested changes to a production application blindly(meaning it should never happen).
> Steeping minutes: Green at 3, black at 4, herbal at 5. Good tea is that simple!

This is simply not true unless you drink cheap tea bags. Some good teas, for example green, should sit for only 10-20 seconds.
+1 to that book suggestion.
Your analysis of ethnic biases sounds plausible in the general case, but in my specific case I'm fairly ignorant of all athletes and sports - I find them all equally unexciting regardless of ethnicity. I realize this puts me in the minority as rest of humankind is concerned.
> The way I see it is that punishing people is work I'd have to do to make a company more effective at something. I want a reward for that. No one will reward me for that. What they will reward me for is shotgunning everyone else

This genuinely doesn’t seem like a strategy that would work.
They don't take a cut of your earnings, they get a commission from the employer - it's a subtle but very important distinction. If there's a $150k job out there and a recruiter gets $30k for a placement, guess how much that job would pay without the recruiter? $150k. It's an expense to the business and one that doesn't impact how much you're going to get paid at the end of the day.

Pretending the recruiter takes "a cut" of your salary creates an unnecessarily adversarial tone.

> I don't really understand the logic behind not being worried about your daughter being infected, because the odds of that are not in fact all that low.

1) Citation needed?
2) Definition of 'all that low' needed?

EDIT: the boss at my daughter's kindergarten had C19 earlier this year, the mandatory quarantine was more of a big deal for her than the C19 itself. She's not talking about "Long Covid", she's not complaining about how bad it was, instead she's back at work looking after our kids.

As a parent of three kids, I've made multiple trips to a local hospital to a) watch the kids be born, and b) get out-of-hours urgent treatment when no local doctor's practice was open.

With multiple kids, it's not a surprise that we're on good terms with the staff at our local doctor's practice. [Un]surprisingly they're [also] pretty skeptical about the whole C19 story. They're even more skeptical about getting tested for C19, something our local government seems to be pushing.
Ask HN: Describe the Perfect Smartwatch
I'm creating a new smartwatch.

I will probably start with off-the-shelf hardware (PineTime?) and focus mainly on the OS/UI/UX. I plan to make everything open source.

I'm looking for the opinion of experienced smartwatch users to better understand what a smartwatch should do.

What's your favorite smartwatch?

What do you like and dislike about existing smartwatches?

What are the most useful and important features?

What are unnecessary features and/or battery hogs?

Describe the perfect smartwatch.
Yes. Not as much as the average CPU but still documented: https://developer.nvidia.com/blog/nvidia-ampere-architecture...

It's Apple's new license agreement specifically for "rental" companies like AWS and MacStadium. Apple specifically says that Mac hardware and software licenses must be for a minimum time period of 24 hours, and cannot be shared between customers.

> Apple requires companies lease hardware and software "in its entirety to an individual or organization," ensuring peak performance and a one customer to one machine setup. Lease periods must be 24 consecutive hours and customers need to review and accept licensing terms for all first- and third-party software.

I understand these abstract cases, because crypto enthusiasts bring them up in every conversation about "dApps" or whatever term they're called now.

I'm looking for specifics, though. As a typical person, what problem do I have that these solve? And why is that problem large enough that I will go out of my way to find a dApp to solve it?

> There's no place to say "I did X" with my item in a way every other app agrees happened, without relying on a central party, and this is really what Bitcoin solves.

That doesn't prove that anything happened with X at all, though. It just proves that someone logged it to a blockchain as such. There is no actual evidence that it's true, only that it's being retold to you as it was originally told to the blockchain.

Worse, there's no proof that any app is exclusively storing/retrieving data on a blockchain. As a user, I'd need a second app to verify that the first app actually did what it claimed -- logged my data to a public chain.
They do look very alike, it's the kind of mistake a human would make. But that's not the problem. The fact that it is automated means these mistakes will happen a lot more, will target dark skinned people more and since a tool can't be fined or put to trial then nobody will be held accountable.
They should add this to the "In The News" section of clearview.ai's website.
> It might be a numbers game for you, but to each of the people you are recruiting they have a lot on the line whether it is leaving a bad job or putting food on the table for their family or whatever else...

It's a numbers game for the candidate, too, as they often apply for dozens of jobs simultaneously. Recruiters also aren't doing it for fun, they're on commission. If they don't make a placement, they don't put food on the table for their families.

Ghosting is impolite, but people do it all the time, including to their dates, friends, etc. The best thing to do is don't take it personally and move on.

How do you go from this story to "ego problem"? It sounds like they have other problems - but doesn't sound like ego is one of them, at least from the story.
The account you quoted describes the police pulling out their guns before he got into the car at all. Evading arrest is not a capital offense and they don't mention that he had a weapon or that they believe he intended to harm anyone, so it's hard to see how pulling their weapons is justified.

It doesn't make sense to use the fact that he hit some stuff while fleeing from the men with guns to justify drawing the guns. In fact, provoking panicked flight seems like a pretty foreseeable outcome of drawing a gun on someone. If I had a gun drawn on me I might very well flee in a panic, potentially hitting cars with mine. They drew the guns before he did any of that and it's reasonable to think them drawing them made those outcomes more likely.

Edit: Here are the NJ deadly use of force standards [1]. My reading of the standards would not allow the use of deadly force in this situation. The rules also state that officers should only unholster their weapons when "circumstances create a reasonable belief that display of a firearm as an element of constructive authority helps establish or maintain control in a potentially dangerous situation." It's hard to see what was "potentially dangerous" in this situation before the guns were drawn.

"cognition gap"

Yeah... this is why I suspect we may see signs of alien life, but just not know what we're looking at. You're not alone in thinking of intelligence as some kind of scalar quantity from bacteria to super beings, and if only we could find creatures in our range, we'll be able to communicate

Embedded in our conception of intelligence is us. We measure intelligence by what we think is important. But creative approaches to fitness in radically different environments will be multidimensional and multivalent, extremely difficult to judge by our own standards

I speculate that if we were to find aliens, we could never communicate beyond basic Skinnerian reward and punishment schema, if that, never mind prime numbers and such, no matter how sophisticated they are. We wouldn't even really be certain if we were witnessing intelligent behavior or autonomic processes, and neither could they. We can't even understand whales or dolphins, and those would be vastly easier to understand than anything without DNA, emergent from a completely different planet

How could we possibly communicate with a civilization that communicates in the time scale of oaktrees, or are sessile, or communicate using flashes of microwaves in patterns we have no hope of even discerning?

You'd think being here on "Hacker News", you'd know that the term "hack" has a variety of usages and meanings. In the case of Americans calling the 2016 Russian propaganda a "hack", it isn't a literal computer hack, it's leveraging Facebook to brainwash the populace into believing an alternate reality in which Clinton is running an underground pedo ring or whatever nonsense conservatives will buy into these days. You know...Obama is coming to take your guns and put you in FEMA camps. It's a hack because it achieves the goal indirectly.

Additionally, you're glossing over the literal computer hacking of Clinton's emails and the DNC.
They have done, but with not so great success (see: VW e-golf) - those cars just aren't designed for it.

I'm not making a prediction, I'm explaining an observation. I don't need implication, just inclusion.
In my opinion to qualify as ghosting a) you need to have had some form of interview beyond the initial half-hour phone screen that went well so that b) the recruiter or hiring manager/person tells you that they are going to 'call you next week' or something similar so that the next action to take is clearly theirs, then c) you never hear from them again.

I've experienced this often enough that whenever I have an interview that goes exceptionally well then I joke with my wife that I'll probably never hear from them again (and that tends to be the case.)

The cost of generating electricity is not really a useful way to think about it if it doesn't look at the cost of generating reliable electricity.

Solar and wind are unreliables and can't actually be used consistently which means that you need to not just factor in the cost of the backup energy but also to take into account that solar and wind are parasitic forms of energy and thus drives up the cost of other forms because they are politically preferred through among other things wind tax credits.

So I don't believe that you are actually describing anything close to the true cost until you start doing something like the above.
Bit of a nit but it often puts people off a service/product if something appears deceptive, even unintentionally:

Have you ever been annoyed about an Amazon review saying "Package arrived flawless after one day, 5 stars"

Amazon doesn't allow that kind of review, I'm sure some slip by but they do have policy against this and enforce it.
"it’s a bit annoying when you don’t know when exactly you should be doing so."

I think that's right, and it isn't very annoying to me because of this exact rule: Don't stop the job hunt until I have one in the bag. It's easier to move on if I don't come to a rest.

I've interviewed enough to have had very good ones that went nowhere and poor ones that got me hired. Having low or no expectations from any one prospect is healthy.

And yeah, even sending a short thanks but no thanks form-email can be emotionally taxing.

> It's very hard to work yourself up about a job without actually caring about it.

I'm very lucky in that my current job hits on most of my skills as well as many of my non-work interests, and that's not a job I'd have to fake anything for, but it's not as if every startup coming down the pike is the greatest thing since sliced bread. This is a skill, and it is one that you can learn to be good at.

That enthusiasm is just the polite enthusiasm of a sales call. It may require a few minutes of reading and thinking (because tbh I also see a lot of folks who have no idea what a company does when they go in to interview), but it is almost always either a baseline "do they get what we do here?" check (which is what you can learn and practice for) or it is a cult you should avoid.
From the hiring side of the table, I can tell you that we're not simply looking for over-eager candidates who are brimming with enthusiasm. We're looking for someone professional who can get the job done without being a pain to work with.

You don't have to show up with exaggerated, faked interested in the company or industry. In fact, it can come off as very fake if a candidate shows up and pretends they're supernaturally excited to work in our industry that they just learned about 2 days prior.

However, you can't expect to show up to a job interview and ooze disinterest and boredom and still be considered for the job.

Don't think of it as getting excited to work for a company. Think about it as getting to know your potential future coworkers. If you need to become emotionally invested in a company before applying, I'd strongly recommend that you work on breaking that habit before it makes your job search artificially difficult.

I found a decent analogy for what I'm talking about:

https://www.history.com/news/beanie-babies-value-criminal-ac...

With a bubble in Beanie Babies there was accompanying fraud and other criminal activity, with most consumers not wittingly participating, but they were affected by it.

So with the asset bubble of the 2000's, this kind of behavior affected everyone, as everyone needs a house.

In another thread I have said I don't blame the masses who may have made bad decisions in hindsight, as they did not have access to all the relevant information. So I do blame the fraudsters, but in the end I really only blame the Fed for keeping interest rates too low, and of course that can circle back around to society as well if you like.

No matter what, there will be consequences for DIY/hobby aircraft, just because cost/weight/complexity are critical factors in a small drone. Most of the planes I fly now are wood/cardboard with a few dumb electrical components. Adding any component will make it harder for newcomers to enter the field.

The FAA has decided that unregulated drone flight is an issue, and no matter what, they're going to tackle it. So I'm happy to see any solution that allows for the continued existence of the DIY part of the industry.

In my mind the "ideal" solution for DIY aircraft is a separate RC receiver-sized transmitter, powered over BEC, that you add to your aircraft when you are flying in conditions that require Remote ID. The transmitter would become another fixed cost in the hobby, but you could use it on whatever aircraft you're flying -- It would be linked to a pilot, instead of a particular aircraft. I have zero knowledge of RF physics and engineering, but I'd be happy if that was possible without a heavy transmitter and significant power consumption.
