You need some sort of smart card/secure element to ensure the ID itself can't be duplicated.
You could have an optional service where the DMV sends you a push notification/SMS every time your ID is scanned.
That makes sense.

Personally, I am not a fan of these ads because their frequency depends on who's willing to pay the most. Also, ads mean that not they are actively looking for revenue. So it's just a matter of time before more things change towards data collection, ads and revenue generation.

Those of you with a webapp or SASS who are currently making $, how did you validate product/market fit? Did you sign up paying customers before quitting your day job? Just trying to get some perspective here.

correct. this is a geocentric device, but that doesn't change how good it is at predicting movements in the sky as viewed from Earth.
It wouldn't surprise me if at least one factor contributing to the higher yield of Asian American students is that they are being discriminated against at Ivy+ schools and have to "settle" for UCs that don't practice affirmation action.
Who cares about whats these (b)(m)illionaires do with their "space" toys?

Virgin galactic would have been interesting 17 years ago right after scaled composites actually won the Ansari X Prize and put a human in "space". 17 years later and multiple spaceX failures and successes later? Much more underwhelming.

Back in 2001 Denis Tito paid 20mil to spend 10 days at the ISS. That is a milestone. Not that Bezos spent 10min in "space" in 2021.
You're correct to observe that more sophisticated value parametrisation might be useful. At least &str (imagine roughly a nicer std::string_view as a built-in type) is on the horizon for Rust.

Because Rust cares a lot about soundness, this gets very tricky for user-defined types. The current idea is that they could be allowed if they derive Eq. What "derive Eq" means in practice is that the compiler is comfortable believing that either you can compare instances of these types to one another with a bit-match or they're composed of types with that property.

You wouldn't be allowed to implement Eq instead for this, because such implementations are safe in Rust, and thus their promises are worthless (Rust has unsafe traits like Allocator, and if you choose to implement those and get it wrong your program has Undefined Behaviour, but by definition that won't happen for a safe trait, even if you deliberately implement it contrary to the specification)

So that rules out floating point numbers because you shouldn't try to compare those to each other with bit matching - NaNs for example.

What does C++ do here? Just YOLO, if you make poor choices the resulting code is nonsense and too bad?

--

We still don't have an example, the constant function pointer thing feels unergonomic to me, I think I'd cook up a Trait representing whatever it is that these functions have in common, and then implement that Trait as necessary to get the same effect by parametrising on the Trait -- but I may very well be missing some affordance your preferred approach has since the equivalent C++ is just to use a Class and finalize the implementations yet you aren't doing that.
I gave it a try in a web browser. To be honest it barely seemed to work, had a frame rate of about 1fps in very simple scenes, and there didn't seem to be anything actually there, just a few empty low-poly rooms. I didn't see any sign of social or metaverse features. The mouse controls are backwards, and that combined with massive lag means looking around is pretty difficult. If you're serious about making such a product, some screenshots and description of the good bits (if you're serious there must be some somewhere) on the home page would be way more effective than making people go into it and mostly just be confused and frustrated.
> That power derives in part from the influence Jewish voters have on presidential elections.

The definition of democratic. This constituency has an issue they care about, and votes for it.

Everyone has a top issue. Some folks vote based on gun control. Some vote based on healthcare. Some vote based on foreign policy. Everyone only gets one Most Important Thing, and if they organize around it shit happens. If there was a constituency that cared as much about changing our Israeli policy then things would change, but alas the folks complaining don’t actually care very much.

If you want a parallel example, look at how the US foreign policy towards Cuba is successfully shaped by a rather small number of Cuban Americans in Florida. They care, they advocate, shit happens.
>NASA could grab someone right now and send them to do science on the ISS for a few months without intensive training.

Wikipedia's page on astronaut training suggests otherwise[0] - becoming an astronaut takes a year and a half to two years of training, and of course to do science on the ISS, you need to be a qualified scientist to begin with. NASA's requirements page[1] says you need a masters' degree in some STEM field.

I'm always a little surprised that Allan Bromley's work is not mentioned in stories about the Antikythera mechanism.

He was one of Michael Wright's collaborators and wrote a lot about it .. unfortunately he died in 2002, cutting short his research.

Ask HN: Interviewing, how much take home work is OK?
I'm interviewing for the first time in a long time.

I'm a 10+ year systems/networking/DevOps eng. I've seen some shit. I've interviewed over 400 people for a FAANG company.

In my current round of interviews, I've been asked hardly any questions of substance. No situational 'how would you solve this?' type questions. There's some basic questions, a coding interview, and then they want to send me home with homework. It feels like a red flag to me. As if the company is fine with pushing off their incompetence into my free time. Every one of these I've gotten, I think, 'You could have spent 35 minutes walking through a similar problem with me to see if I'm in the right path to solve the issues you have in your day to day. So far, I've just dropped any company that assigns homework. I'm not applying for a Sr. level role, just wanna make widgets and like most of us in this industry, I just read a book and then pull up the docs of the stack I'm working with and figure it out.

It's been so frequent in this recent job search that I can't tell if that's just the way things are done now or if it's a real red flag that says the company won't respect my time or competency.

What gives? Have things changed? Am I out of touch? Is that a red flag or just the way we do things now?
The fact that people have to speculate this shows IMHO nicely not just that there are no clear borders between peoples "race" but that the concept of race seems pretty pointless.

Sounds like GW copied that from Heinlein's Starship Troopers, or maybe Enders Game.

In practice, it could be done pretty securely and cheaply.

In the US, the 2D barcode (PDF417) contains no signature, only a plaintext duplicate of the information on the face of the card. It's intended purely for convenience. Nonetheless, it's not too uncommon for bouncers to use an app to read the barcode because counterfeiters will surprisingly often generate the barcode improperly (causing failure to parse against the AAMVA specification) or outright duplicate it from another ID such that none of the information matches the face of the card. The specification for the barcode payload is a bit obtuse but it's available online and there are plenty of libraries out there for parsing and generating them.

Most US driver's licenses also include a 1D barcode along the top edge that contains just an excerpt of the information from the face. This is also according to an AAMVA standard.
Note the spaceshiptwo pilots already have commercial astronaut wings from earlier flights.
NASA has 13 astronauts, the entirety of the 2017 class, who have a combined total time in space that is less than Jeff Bezos has. Which is to say none of them have been in space and when they do go t will be aboard commercial spacecraft. If they happen to take a trip on top of a falcon 9 rocket in a crew dragon capsule, they will be passengers. Yet they are currently called astronauts and would likely be given “wings” upon completion of their first flight as a passenger on a crew dragon.
I'm sure you could and do.
Well, it depends what you meant when you said "why they continue to be so successful.". If you compare iOS to Android, Android outsells it by vast numbers. If you compare macOS to Windows, Windows outsells it by vast numbers. How do they hold a niche by making nice products? Well they make nice high-end luxurious feeling products and that's surely enough.

If you take it more like "why do so many devs use macOS when they could have open source fully customisable Linux/BSD" which is in some ways their real "surprising" success given that they are more expensive and less customisable, the answer falls out in every HN thread about Apple - they build things which let people get on with their work. People get fed up of fighting suspend mode or wifi config or high-DPI displays or sound drivers or web video or breaking upgrades or regularly needing to edit config files to keep things basically working, and Apple makes all that go away. And that increasingly applies to Microsoft/Windows, people on HN often say things like "Win 10 ads in the start menu and telemetry is the last straw, I bought a Mac" or "I'm fed up of Windows update reboots interrupting me, I bought an M1 laptop", but they don't say nearly as much "I use macOS for the consistency of UI aesthetic". [Although people do say things like that about choosing iOS instead of Android]

Syncthing would compare to Google Drive or Microsoft OneDrive, but it's the ecosystem and developer attitude towards users that I'm pointing to, not the file sync part. Apple walk the fine line between taking options away vs forcing you to deal with plumbing, easily well enough to keep their niche market share. "I actively dislike a lot of the way they dumb down interfaces, but I acknowledge that's something the vast majority of users won't ever care about." - including plenty of tech users who don't care.

Most folks don't want to share the roads with drunken teenage drivers.

Don't get me wrong -- some teens are probably more than responsible enough to be trusted with controlling their own drinking. However, it's those that aren't that're the concern.

Parents generally don't want to have to worry about bars being allowed to serve their kids, either. Maybe not all parents feel that way, though I'd guess that those who'd be against their kids drinking would tend to have stronger feelings on the topic than those who'd be okay with it.

That makes about as much sense as current scientific naming.

The way we name people makes sense - with a family name, and an individual name.

Conversely it makes no sense for scientific objects. As an example, 'Higgs boson' does not make sense. 'Higgs' gives no clue what the particle is. Is Peter Higgs a worthy person? Etc. Since it is the mass-carrying particle, it should clearly be called the 'masson', 'massion' or similar.

I’m not insisting that’s what the word means. That’s how it’s defined in the dictionary.

https://www.dictionary.com/browse/conspire

It’s usually used to describe something secretive, or illegal, or wrongful on some level (and anything can be considered wrongful or harmful depending on your perspective), but that’s certainly not a required condition by definition.

Just about everything the government does is by definition part of a conspiracy. Everything the government does in secret is most certainly part of a conspiracy.

The word has just be morphed into having a seperate implied meaning, where people simply describe something as a “conspiracy” or “conspiracy theory” as a way of dismissing a claim or criticism without actually engaging with it on any level. This article describes a conspiracy fact, and as far as I can tell, none of the facts reported in the article are in dispute.

One of the parent commenters postulates a motive, a claim which is dismissed by suggesting that would be a conspiracy. That response lacks any level of substance whatsoever, because it is factually a conspiracy no matter what the motive.
As far as control interface goes, it seems almost inevitable that we'll eventually have a breakthrough/refinement for some sort of mental control without physical movement (similar to how some amputees control their advanced prosthetics). It would be a game changer for VR.
The counterargument to this is that there is evidence young people are neurologically not full adults at 18 years of age, and alcohol impedes neurological development.

I have no doubt war also has neurological effects, but they don't seem to be age specific.

It is challenging, if not impossible, to otherwise defend it. If someone has the possibility to choose (or be forced) to harm themselves and shorten their life in war, then why shouldn't a choice apply to alcohol?
> We live in a country that has the rule of law, you can't just arbitrarily use a vague characterization of a country being "hostile" to abridge the rights of someone.

There is no ambiguity in the classification of North Korea as a hostile regime. Not only there is the fact that the Korean war never ended with a peace treaty an only had an armistice, there is also the hostile and recently degrading relationship that in 2020 escalated to the total elimination of official communication lines between north and south Korea.
Seems like an appeal to nature fallacy. If humans are ensuring that the plants reproduce, you don’t need to ‘set the dial lower.’ Almost all of our fruits and vegetables provide more nourishment than their naturally occurring counterparts. This is merely a continuation of that process.

Pretty sure it's just a public data format with the same info as on the physical license. The design specs are here: https://www.aamva.org/DL-ID-Card-Design-Standard/

Decent quality fakes will have the correct info in the barcode as well. I guess it weeds out the cheap ones at least? At my cousin's sorority they'd just find a similar-looking girl over 21 who would "lose" her ID and request a replacement, not sure how a bouncer would be able to detect that.
No, they definitely can. I just don't expect someone who cannot relate at all to care. I would want everyone to get a livable wage.
That's not what "died within 28 days" means; correlation does not imply causation. In fact, the data linked lacks any cause of death; without that column, we should assume these numbers are all cause of death, from respiratory failure to blunt-force trauma.

When I was in college, the laws were not quite so strict as they are now: in that state, persons over 18 could purchase 3.2 beer (3.2% alcohol by volume). Still, a fraternity or fraternities would bring in a fake-ID manufacturer every fall. Somebody on the student paper wanted to do an article on it. But his boss or bosses had had such a fake id. The article never ran.

Let me add that the age of drinking was set to 21 across the country because the Reagan administration did not wish to make airbags mandatory. It was argued that raising the drinking age would produce an equivalent or greater savings in life compared to mandating airbags in new cars. The Department of Transportation could withhold funds from any state that allowed those under 21 to purchase alcoholic beverages.

Those of you younger than I am will know how much effect raising the drinking age really had. My impression is, Not much.
This author is almost as skilled as the staff at my local AMC Theatre, where I was a bystander to a woman getting denied a beer on account of her Washington, D.C. driver's license not being a "state-issued ID".

Can't speak for parent commenter, but there is a nugget of supreme wisdom in the remark nonetheless. Gamedev is notoriously punishing and mentally grueling. Pushing through these roadblock moments CAN lead to huge runaway successes if the market timing is right.

I'm in a field in no way orthogonal to gaming, but I can attest myself that pushing though the moments I -wanted- to quit the most, were the moments that yielded the most amount of advantage to me. I knew I could go further, work harder, learn to be smarter, because I knew that I had persevered where most others would've called it quits.

Hopefully that's what they mean.
I forgot to add one other factor .. taxes. The Canadian tax system is a bit weird when it comes to dealing with married people. Do understand that vs. USA. If you and your partner work, you might do pretty well making 150-180K (assuming partner makes same). The tax rate goes up pretty fast.
That's similar to the way you could say the founder's startup Moonfruit which launched back in 2000 was more about producing Flash SWF files than websites. Maybe the model has some traction for a group of people who find that sort of help applicable or not harmful to their own business model.
> Anything related to income will be (statistically speaking) associated with intelligence and other personal traits (perseverance etc). Any of this will be obviously correlated with your kid's SAT --- it's called genetics.

No, it's called social darwinism.
There's been multiple efforts towards some type of PKI verification of driver's licenses, but they've all failed to gain adoption for various reasons. Perhaps the simplest is this one: driver's licenses are not really intended by the state to be verifiable offline, as in basically every case the state has to verify a driver's license they will need to perform an online check anyway (for revocation, for example, if not also for warrants and the whole NCIC gamut). So the level of motivation for the state (and more specifically the AAMVA which promulgates standards for driver's license) to implement this kind of verification is pretty low. Add to that the moral hazard of normalizing digital imaging of driver's licenses (which is a real concern as "digital ID" schemes or anything that looks like one face significant political opposition in the US) and practical challenges (cryptographic signatures compact enough to add to the PDF417 are possible but not as well standardized, the federal government has consolidated cryptographic ID efforts on ICC "smart cards" which are costly) and it's just a hard sell.
There is nothing wrong with them. The HashiCorp touch maybe envisions something I did not think about before.

A common measurement standard for a cup of coffee is 6 oz.

If this is a 6 oz cup of normal-strength (i.e., weak) coffee, then that's only 36 oz, or three soda cans. What if you consume what's now considered normal, which seems quite strong? Two soda cans?

How large is a mug, which people associate conceptually with "a cup"?
> No we are not. The constitution specifically says that only congress can declare war, and congress has made no such declaration.

Do note that the US never declared war on Iraq, and that did not stopped it from fighting two wars that were very real, both of which with the support of an international coalition.
Only takes a couple folks who want to use all the esoteric features of c++ at your workplace in a culture where nobody can tell them “no” (which is increasingly common) and big chunks of your codebase can evolve into unmanageable mess. Tbf i found the same to be true with Python but not with languages like Java, C# and especially Go

How so?

> Also this works nicely for self contained dependencies, and much less nicely for not self contained dependencies.

Doesn't matter. You said: "You can speak for everyone." which is simply not true, as I have outlined. You didn't say anything about not self contained dependencies or whatnot. The person you replied to said "I spent an unconscionable amount of time managing dependencies and libraries in C++" and I... well, don't. So clearly not everybody does.
