More efficient conversion of sunlight electricity doesn't mean the cells are cost effective for putting on a house.

On a luxury car like this, area is constrained and money is no object, so it may make sense to use otherwise prohibitively expensive cells to win a few extra percent efficiency. Similarly, such multi-junction cells are used on spacecraft, where the lower mass per watt makes it worthwhile.
These sorts of "currency" are typically invested in short term, low-risk deposits. Think bank certificates of deposit, US treasuries and the equivalents in foreign currencies.
> This is one of the reasons I dropped out of crypto for years, most of its supporters were completely delusional and tragically uninformed about actual banks.

The reason I stayed in is because Bitcoin solved a seemingly intractable problem, it works in the real world, and it's survived and even thrived in the face of fierce attacks for a decade.

Yes, there are many shills who are delusional and ignorant. Yes, speculators and fraudsters are running wild.

None of that changes the fundamental characteristics that make this a fascinating and promising technology, network and social movement.
Panels are heavy, cells aren’t. In the extreme (https://en.wikipedia.org/wiki/Thin-film_solar_cell) ”Film thickness varies from a few nanometers (nm) to tens of micrometers (µm)”

That still has to be mounted on something, but that something easily could be the car’s structure (and it is. The site says ”The roof and hood of Lightyear One comprise of five square meters of integrated solar cells within safety glass”)

But yes, the power budget still will be small.
Javascript might not add much value to the reader/end user, but it can/might have made building the above 3 functionalities much faster and easier for the developer. Without Javascript we simply might not have all those great content to begin with.

I just quit a gig at a semiconductor supplier that makes EUV light. Keep in mind this is just one major component in the chain:

- EUV comes from a plasma of metal created in a vacuum chamber.

- the plasma is created by concentrating a beam of light on a tiny pellet of molten metal

- that beam of light is a 25kw laser, which is borderline weapons-grade. To the point that countries hesitate to even allow it to be imported.

- the laser must be pulsed precisely to vaporize the metal as its flying through the chamber

- residue from the metal vapor quickly builds up and deteriorates the process

getting this stuff to work requires armies of engineers and scientists. the machines themselves are the size of a tour bus.

The Tanakh also has the distinction of being one of the few works of literature that has survived for 3000 years largely intact, and I think it's considerably longer than the older parts of the Egyptian Book of the Dead.
Alternative take: some mental illnesses, anxiety disorders in particular, are exacerbated by knowledge of them and their immediate effects. Anxiety is much easier to deal with when you're not anxious about the fact that you are or will be anxious.

Maintaining a "stiff upper lip" means learning to ignore unpleasant symptoms, which can both reduce their frequency and severity. There is usefulness in "manning up", to use an increasingly unpopular turn of phrase. I disagree with the increasingly common idea that suppressing one's negative emotions is generally harmful.

You're glossing right over what's happening here. Customs is expecting FedEx to _enforce_ law. Not comply with it, enforce it. Preventing a package from crossing the border on a legality basis is not the responsibility of any private entity in the United States. We have official agencies who act in that capacity and have authority to do so.

So, no, it is nothing like putting seatbelts in cars or not polluting rivers. Equivalent would be forcing car makers to ensure customers wear their seatbelts or companies keep rivers at a certain level of pollution (regardless of their complicity in its pollution).

I'm honestly surprised Cameo is doing as well as it is. To me, I personally find it sort of cheesy. I didn't purchase a Cameo or anything, but I did sign up on the service to see what it was like, and who all was on it. It seemed to be filled with quite a range of actors/actresses/celebs/etc. but since each of them were basically just reading a cliché "happy birthday" type script with insert {blank} name into the Cameo, it just felt disingenuous to me. A lot of actors also seemed to really "phone it in" for it. I was surprised how much people were paying for these, to be frank. If I received one from a friend, I just don't think I'd see the value, and I'm even a big tv/movie fan. "So, you just paid a celeb to say a few lines? Okay, neat, I guess?" I feel like it was probably more unique at the start when X friend didn't realize you had easy access to the celeb, so it felt like "OMG, how did you get them to do/say that?!" But now that it's getting more popular, it seems to me the value of it being unique would get washed out fast. ¯\_(ツ)_/¯

I think the best way for Cameo to actually expand would be to open it up to allow you to book a celeb for more than just a quick little video blurb. Like being able to invite them to parties, or events, and pay them for an actual true "cameo." It would obviously come with a price, but to me, that would be much more innovative.
There is so many things you could do to make things go well on very small devices that would cost almost nothing today, if we decided to adopt interface and software standards to run on durable hardware.

Meanwhile phones are always getting faster and faster and always becoming obsolete every year. Throwing software away means we are forced to throw hardware away.

I wish that someday we could just decide to stick to a single system and not change things, so that system can last 10 years and work on the same durable phone. It would require making hard choices in OS and software design, but it would be really worth it.

I hope a day will come where computers or smartphones will be able to last 10 or maybe 20 years and still be affordable. To be honest I don't think I want to be involved in learning how to develop apps on any phone for those reasons. At least microsoft and linux are able to maintain a minimal amount of backward compatibility. For developers that's really important. You don't have a good ecosystem or a good phone if you cannot attract developers to build apps.

It's almost guaranteed to get challenged in court, at which point the judiciary will determine whether it is congruent with existing legislation.

Worst-case it's not, and congress will probably take up a similar initiative so as not to appear ineffective.
Learning it is challenging but achievable by most interested programmers. It's vastly different than most mainstream languages so it's not as easy to pick up as C# is to a C++ programmer because so few concepts translate from C++ to Haskell. But it's not impossible if you're seriously interested.

You also don't have to learn all of it to start using it. The majority of code I write in Haskell doesn't use anything more fancy than function composition, ADTs, and some type classes. You can do programming at the type level but that's not a requirement for entry.

A bank takes in deposits then lends them out, when trying to understand a bank it makes sense to talk about them in those terms, because if it isn't doing those things, it is really a bank.

Thank you. I would add to this that prior to it coming before the judge there is the leverage of "We can get 600 mil now or go into years and years of litigation that we have a non-zero chance of losing, and all we have to do is agree to let them hide their documents." hindsight is 20/20, how many would really choose the years and years of litigation over the payout?

I actually fall into a third bucket, at least when it came to math courses: I'd attempt to work ahead of the instructor during the lecture, instead of just writing notes or just listening.

Because of the way well-done math courses are structured, with topics building on each other, I was able to do this about half the time. Most importantly, any mistakes I made would be almost immediately corrected, so I never learned the material wrong, like if I'd waited until the homework.

The value of the false positive rate is that it lets you know the probability of a true-miss. Depending on the classification exercise, you may be concerned with false positives, where the consequence of a missed call is significantly greater than an unwarranted checkup from a human doctor.
> a life saving drug

I think you are technically correct that Truvada is a life saving drug but I feel you are being dishonest. If you exclude occupations where you could be exposed to HIV, most of the US users of Truvada could choose to change their behaviors and reduce their chance of contracting HIV to <1%.

There is also the general trend that US companies pay large amounts of money to develop drugs, charge US customers enough to cover R&D costs and then sell the drugs at cost internationally. Does that suck for us? Yes, but it helps the rest of the world significantly.

This seems to be a general problem across the peer-to-peer rental industry. My friend had her car stolen while renting it out on Getaround and ended up in a similar situation.

These things seem to come and go in cycles. Airbnb and Uber faced several similar trust & safety issues of their own before they started building in much stronger safety and insurance protections and, crucially, convincing their customer base to continue trusting them. Now that their hard work has once again given people confidence in the P2P rental model, these upstarts are swooping in with none of the protections and reaping the benefits.

> The white paper explicitly gives the Libra Association (i.e. Facebook and its partner validators) governance control over the cryptocurrency.

> Here's an easy scenario to imagine that shows how incentives would get misaligned: Facebook and the other validating nodes of Libra are financially compensated by interest from the collateral for Libra tokens. If Libra is successful in its mission, it will become a global currency that's stronger than the assets that underly its collateral.

> When this happens, suddenly Libra being a collateralized stablecoin stops making sense. Kind of like when the US Dollar no longer needed to be backed by gold since it was a strong enough currency/unit of financial measurement on its own. The US then got rid of the gold standard and has since saved itself untold money in custodial expenses they would have been paying to hold all that gold.

> The Association would never do this for the Libra however since it is literally how they are funding their own operation. Even if it's in the best interest of all Libra users, the centralized governance association with all of the authority to make this improvement would choose not to because it's not in their best interest to do so.

> There's no leap of imagination there - it's just how power and incentives work.

Your basing this argument on the fractional reserve monetary policy that the libra association is hedging against. I believe we are moving towards a world in which global currencies become the norm. There will be 2 types of global currencies, corporate currencies and decentralized currencies, aka Libra and Bitcoin.
Both forms will have to have a mechanism that prevents inflation, Libra will do that by being fully backed, Bitcoin does that through Nakamoto consensus.
With digital currencies it becomes possible to move your entire "cash" holdings in a matter of minutes, so a fixed supply currency like Bitcoin insures that Libra will never dilute it's supply because the barrier to exit the currency is so low. In democratic countries like the US the mechanic that prevents massive inflation is mostly voters' influence over the federal reserve. Of course it isn't perfect the dollar has been inflated ~300% since leaving the gold standard. With corporate global currencies we don't have such voting powers.

Also after doing a little math the battery is larger than the entry level Model 3 and the same size as the Bolt. Plus this car is longer and wider than both the Model 3 and Bolt (although it is shorter than both so I guess it could be somewhat more aerodynamic). I just don't see where they cut any substantial amount of weight. I am rather dubious on all their claims.
As another nuance, some dry counties have had pretty strict enforcement of public intoxication laws as well (as in if you can't legally drive, don't try walking home from a friends house either), while others were no different than wet counties.
Seems really convenient to claim that because of an edge-case that no price-transparency is possible. Americans seem to have a habit of claiming things are impossible/infeasible that plenty of other western nations have managed to implement successfully decades ago.

Edit: To clarify I am an American myself and this irritates me.
I don't know how long a pen lasts, but the insurance in my country pays about 40€ for five pens.
My wife and I agreed years ago that we would have a discussion before either of us makes a purchase of about $20 or more. (We haven't adhered to that perfectly, but it has been a great guideline.) Oddly, we failed to notice that we never have that discussion when it comes to health care, even though the vast majority of our interactions with the health care system are certainly not emergencies. We routinely go to a doctor, we don't ask what it will cost, we do whatever the doctor asks, and insurance covers only part of the bill. Health care is the only exception to our $20 rule. How odd...

We realized we've been bamboozled. Nearly every hospital and clinic uses the same trick: the doctors apparently don't know what anything costs, the office staff say they don't know what anything will cost us because it depends on the insurance, and the insurance company won't reveal the price until the office staff charges the insurance. All the indirection makes it difficult to determine even a ballpark figure. (It no longer surprises me when the hospital charges $4000 per night to merely sleep in a bed with nurses and doctors nearby.)

We decided we're no longer going to make an exception for health care (except in emergencies). We're going to require a price ahead of time so we can discuss it like we do everything else. We intend to annoy the office staff and insurance company until they comply and tell us what the prices will be. We think about it this way: heavy expenses can easily cause stress that reduce our quality of life, significantly offsetting whatever we might gain from medical procedures.

I'm glad the legislation seems to be working in our favor.
Using the :D emoji at the end is a way for the author to reiterate the "No offense but..." type statement. The problem is, if they use that, it's likely they recognize their comment can be taken the wrong way and should have just rephrased it instead of taking the easy way out with the :D.

I mean in the context of creating a new account, when the 1p app pops up in a password field, AFAIK there's no way from that to create a password. So you have to go into the app, generate one, then back out of the app and back to the app you're creating the password for.

Ah, if I misread then from the results section of the linked paper:

For the malignancy prediction objective, the algorithm obtained an area under the receiver operating characteristic curve (AUC) of 0.91 (95% CI: 0.89, 0.93), with specificity of 77.3% (95% CI: 69.2%, 85.4%) at a sensitivity of 87%.

I haven't read the papers methods, but the data set size is small-ish for this sort of analysis.
