In theory you only need to trust the hardware to be correct, since it doesn't have the decryption key the worst it can do is give you a wrong answer. In theory.

But can you trust the hardware encryption to not be backdoored, by design?

That's my point, this sounds like a way to create a backdoor for at-rest data.


By design, you don't trust it. You never hand out the keys so there's no secret to back door. The task is never unencrypted, at rest or otherwise.

You can if the manufacturer has a track record that refutes the notion, and especially if they have verifiable hardware matching publicly disclosed circuit designs. But this is Intel, with their track record, I wouldn't trust it even if the schematics were public. Intel ME not being disable-able by consumers, while being entirely omitted for certain classes of government buyers tells me everything I need to know.

There is no hardware encryption or decryption.

I encrypt some data and keep the key. I send the encrypted data to you (probably some cloud provider). I tell you to do some operations on the data. I don't tell you the key or what the data is or what the operations mean. You send the results back to me. I use the key to decrypt them.

You have helped me with my compute task, but the data you have is totally meaningless without the key, and only I have the key.

It's hard to believe that it's possible to make encryption where this can do useful work, but it is.


Well yeah... You do the initial encryption yourself by whatever means you trust

I get the feeling honestly it seems more expensive and more effort to backdoor it..


American microwaves almost always have a fairly easy way to change the power level, it's just nobody bothers to use it.


Usually the 'look' is not the issue as much as the geocoder (which you are only allowed to use with a google basemap, no that clever idea you have isn't going to work), like clients are often excited to use a more customizable basemap but balk when it comes to other geocoders which are nice but are not the google one which people really really are used to.


Yeah this was a major problem for us as well. Luckily we can just replace the map, and we'll continue to use the Geocoder and address lookups elsewhere. Its kind of crazy how much better it is with "newer" US addresses vs everything else we've tried.


not OP but the google maps API doesn't actually support other vector tiles (and other map libraries are not allowed to use the google map basemap) which means it's not easy to just have two versions of the site that differ only in basemap


In your example crypto would only replace the visa network. Most of the fee you are playing is to Airbnb for getting you the client in the first place.


Correct, but these fees are trending up and not down, its not uncommon in this space to see payment fees hitting 15%. Removing the primitives of payment requirements, rails which are hard to build and practicably a monopoly, would free the state, this would power end-users instead of building more monopolies.


Actual payment fees are hitting a couple % max, all the rest is platform fees which are orthogonal to how you are paying. If you sell something through airbnb, they will get a cut no matter how you pay.

Credit card fees are a great deal for consumers even when they are added as a surcharge or there is a cash discount. Not having to deal with cash AND being able to dispute transactions are significant benefits.


A Veteran health ID card is a government issued photo id card used to prove your identity with the government to get health care, why wouldn't it be allowed for proving your identity with the TSA.

It's because technically the dollar is divided into Dimes, Cents, and Mil. (this is why dimes say 'One Dime' on them instead of 'Ten Cents'.

So while the mil isn't really used anywhere else that regular people see any more due to inflation, it is a valid division of the dollar and that's why they are able to get away with it.


> (this is why dimes say 'One Dime' on them instead of 'Ten Cents'.

No, it's purely stylistic. We tend to spell out denominations on coinage and "dime" is just the American spelling of disme, meaning a tenth.

The capped bust dime from 1809-1839 had "10 C." rather than "One Dime". Similarly, the capped bust quarter said "25 C." instead of the modern "Quarter Dollar", the half dollar said "50 C." rather than the later "Half Dollar" and the half dime said "5 C." rather than the later "Half Dime."

Most of the 18th century and early 19th century coinage, besides half pennies and pennies didn't have their denomination written on them at all.


There is no such decipence division in the UK, but fuel is still sold with a vestigial .9 pence on the end. In fact, since the denomination is per litre, not gallon, the .9 is about 4 times more significant.

When the final calculation of XX.YYY litres * AAA.9 pence/litre is done, it's then rounded off to 1 pence.

Currency conversions are also frequently done with readers that aren't a round multiple of pence, even in official government tables: https://www.trade-tariff.service.gov.uk/exchange_rates/view/...


I'd like to clarify that point a bit.

They're allowed to get away with it because of a dysfunctional lobbying driven government. Mils don't exist in the common knowledge and if any reasonable person looked at this they'd call it out. It is useful in accounting but a Mill has never been minted and the last half penny was minted in 1857. It has never been possible using issued physical legal tender in the US to pay a debt of $3.129

The Mill doesn't exist because of some archaic need - it's pure dysfunction and the utilization of it in gas prices is a practice that should and very easily could be made illegal.


Yes, the "Mill" discussion looks to be totally irrelevant. [1] and [2] seem to back up my claim that, at least in modern times, it's purely a "just-below pricing" psychological trick and has nothing to do with the Mill unit.

$4.999 looks a lot smaller than $5.00 to everyday people and it makes the gas company more money than $4.99. That's all there is to it.

Certain states have manufactured plastic mill tokens in the 1920s and 30s to aid in the payment of taxes: https://en.wikipedia.org/wiki/Sales_tax_token


So do whatever they do with mils but for the penny too. They don’t nor have they ever minted a mil coin, so the procedure for this is already well established if this is correct.


Has a Mil ever been minted?


It has not - and it's been more than 150 years since the last sub-cent denomination (the half penny) was minted.


Not by the US mint but they exist: https://en.wikipedia.org/wiki/Sales_tax_token


Any time you have to divide up a range of things into distinct buckets you get weird corner cases. Many states tax restaurant meals different from groceries and thus must decide on where the exact difference between buying a single donut (this is obviously food for now and this treated like restaurant food) and a dozen donuts (this is food for later so obviously a grocery).

Comic books are much more "magazine like" then "book like" in practice so it's not surprising they are treated similarly.


You are confusing "democracy as used colloquially for government" and "democracy as used by computer scientists to design systems that still work on failure prone networks"


So first off, no shit the college board things the SAT measures good stuff, it's their test.

Second nobody said the SATs don't measure something, but that something is ability to take an SAT test which is highly predictive of how well you can take other tests. Which as our society puts lots of stock into tests isn't nothing but it's not measuring anything inate.
