Because you can make it so that the required certificate/signature has to meet certain criteria to work. For instance, imagine there was a PayPal equivalent type app for paying QR codes, and they required all codes to be signed by one of their business customers (who they have on file). Or with a certificate they themselves issue their customers.

A tea bag floats though. It’s better to use the traditional balls or anything else metal that will make the tea sink so it soaks better. Alternatively, there are ceramic teapots that keep the tea leaves below the water level.

It wouldn’t need a separate app if, for instance, a standard QR payment format way created. If you just want a link to a website to pay, then naturally that would be less secure, but you could always put the URL below the QR code for redundancy (QR would only save time typing then).

QR codes are mostly meant to let you get an amount of info (they’re mostly text-based) without having to type or enter it manually when you might make mistakes or when the process is just faster for the amount of text involved.

If it becomes standard for public parking to be signed, everyone would know. If payment QR codes in general start being signed, your payment app might even know. Lastly there could even be signage by the code to help novices.

Plenty of people I know have gotten the little echo dots or the bigger alternative with larger speakers for Christmas or birthdays. Technically they didn’t spend money, but their friends and family did.

Does it make a difference that the tea is never in the microwave? It’s only the method for heating a single cup of water, not of heating the water+tea set.

I think part if the motivation here would be to allow the doctor present at a school to determine whether a child is participating in the correct sex-appropriate placement. Like using the correct locker rooms or bathrooms in case teachers or other students bring up an issue (for example if a boy were to go into a girl’s locker room and claim to really be a girl). Since appearance doesn’t line up with sex in many cases nowadays, the inspection would be to determine the real sex of the individual. Some school activities will involve nudity (changing before entering a swimming pool, communal showering after a sports match or gym class, etc.) so the authors of this were initially pushing for any teacher (such as the supervisor in a locker room or the teacher of the associated class) to be able to inspect/determine the sex of the individual.

Neither. Tea bags are for chumps. It’s so much tastier to use fresher loose tea leaves of whatever mix you prefer (and you can control how strong you make it, plus you end up with less waste). I just boil the water in the microwave then when it’s hot I take it out and add the tea.

This seems to be a gross misunderstanding of public key cryptography. Public keys allow you to verify an existing signature is valid and made by the correct entity, but they absolutely don’t allow you to forge a signature: that’s actually what they are designed to prevent.

You pay CAs for certificate issuance, not for signing. You could sign all the QR codes in a city with a single CA-issued certificate as long as the standards for it were all accepted.

Well, because it won’t be signed by a trusted CA for that task. Like if CAs had a category of certificate issuance that applied here (the standardisation issue) then it would be easy to spot a fake (which wouldn’t be correctly signed). Alternatively, you could take the European approach of having everything government related (like public street parking, though Europe mostly uses apps for that, not signed QR codes) rely on government entities and those in turn on a national set of government CAs.

Licking a wound isn’t grooming or maintenance though.

Well that’s rather concerning about the future rule of law, and the ability of the FBI to conduct investigations without political interference…

They’d be able to help secure Europe, could get some sales to EU countries and such, but I see this as a project that would deal directly with established armies (and countries’ defence budgets) rather than going through the EU.

While that’s fine for a situation in which an European army existed, Orban would almost certainly veto such a proposal. In fact, he’d probably veto the EU spending a substantial amount together and call the EU warmongers. The solution is to have countries act independently on paper (with leadership coordinating) so that the EU doesn’t have to get involved in such a way that vetoes can block progress. That’s just the state of affairs at the moment.
