I'm not sure I would source non-Chinese electronic components from Aliexpress... (unless it's just to play with them, definitely not for a product): you might need to check their reliability and quality. Pretty sure that Sensirion themselves are not selling there, so they are probably either clones, fakes, recycled ones, or if you are lucky authentic ones that for some reason ended up there (but I can't imagine a way).

Chinese fabs are notorious for running secret shifts that make their customers’ chips to sell themselves. They’re the exact same chip but made without authorization, using the customer’s exact design.
That said, Sensirion has their own CMOS fabs in Switzerland so that’s very unlikely to be the case here. If they work at all, the counterfeit chips are probably some Chinese CO2 sensor IC that's small enough to fit into the same package, lightly customized to fit the pinout of the original. Or it's just a microcontroller inside faking it a la FTDI.
Huh, good points.
It doesn't seem to be just a micro sensor faking it, as it reacts as expected for example when opening the windows.
I guess the only way to tell if they are any good is to buy a verified good CO2 sensor and compare the outputs then.
Has any paperless user found a good way to "deskew" scanned pages?
Sometimes, when scanning from my Brother printer through the ADF, the pages are skewed/rotated and it can be pretty jarring.
My guess is the difference lies in the fact that the EU limits credit card fees to something around 0.5%
That means the CC companies can't offload the financial burden of this onto the vendors (and they in turn onto their customers), which leads to them having an actual incentive to improve security.

Most CC company (CCC) revenue comes from charging the poor people who can't pay their bills ("interest"). Merchant fees are only a small portion of revenue for most cards [1]. In the case of Discover for example it's less than 10% of their revenue, and in the case of Amex it's less than 33%. Other cards fall in-between.
Your link explains that the issuing banks charge interest, not the credit card companies - which are merely the payment processors. I don't know all of the companies listed, it's possible that some are two in one and have their own bank as well. Some payment processors are partly owned by major banks too. But take the largest CC company, Visa: They don't extend credit at all, they don't even issue their own cards iirc. All their profit comes from fees, because the fees are too damn high™.
They've successfully convinced the public of the opposite though. It's a very common misconception that only "suckers" who buy on credit pay for it and that everyone else is getting a free service as long as they pay off their cards in time. In reality everyone pays because the merchants have to pay those fees and they pass the cost on to the consumer.
There's a recurring myth, very prevalent in the US, that credit card companies would prefer people who pay off their bills every month as cheap margin versus being predatory. It's bizarre, and as you've pointed out, completely unsupported by how they actually make their money.
This seems to ignore losses and credit risk entirely. Someone who pays off their bill every month has no credit risk and the fees earned are unimputed revenues. I’m not saying their analysis is entirely wrong, but I would expect unsecured credit losses to be fairly high in the consumer credit market.
French residents are most likely still paying income tax in France (and in Switzerland too), as France most likely has a bilateral tax agreement with Switzerland. They are also taxed according to where their company (or their main place of work) is located. French citizens living in Switzerland only pay taxes in Switzerland.
It‘s also surely only for „security“ that all the neutered adblockers only work with Safari itself and not on any other apps using the Webkit Rendering …
As far as I understood it, Hyper-V is a native hypervisor like Xen or ESXi. So if you're using Hyper-V even your Windows is running as Guest alongside any other Hyper-V VMs and WSL2.
> The DID stop adding stretch goals/scope creep.
Probably because it drew major criticism and they simply found out people would throw even more money at them if they simply kept "releasing" new ships (or rather their concept art).
I think it's an unfair comparison only because they make it clear that a "pledge" is to support development of the game. Like getting a keychain from a patreon artist.
But it's ultimately unprecedented, and we are all learning as we go. I doubt there will be a crowd funded game like this again for a while.
The problem is that as soon as you're getting value from users solving captchas, there's an incentive to show them more captchas to solve before accepting that they're human.
