Thanks for the recommendation, I'll check out Flowx.
A while back I installed quite a few weather apps on Android, at the time, I felt wX and QuickWeather (from F-Droid) were the best. Maybe Flowx will be even better :-)
In the countries that you think of as having 'strong, fair, and just judicial systems' governments typically control only the fiscal policy. Monetary policy is left to some independent entity. For countries with fixed exchange rates it is also impossible to have autonomous monetary policy without imposing restrictions on capital mobility. This also applies to blocks of countries, e.g., none of the individual governments of euro countries have control over the bloc's monetary policy.
But that was my point exactly. Sure, you can live in Sweden without even knowing how cash looks like so it is cashless in a way. But, if the cash register is not functioning then you are done* with or without cash in your pocket.
* I'd wager that if you know the prices and keep track of what you sell, you'd be fine recording the transactions after the fact.
I wouldn’t be surprised if it’s illegal to accept payment without offering a receipt with all of the correct info, which among a bunch of things include a unique incrementing receipt number.
> Yes but how does the cashier know what the price is?
My understanding was that it was just payment processing that was affected, not the point of sale systems. The scanners and things probably work fine, and I think they could accept cash payments without issue. It’s just not worth it when almost no customer pays with cash.
In this code, the main problem---I think---is that there are intermediate results that are being allocated, e.g., Fk_1 * Pu * Fk_1'. I will speculate that you could improve on the baseline code by preallocating these in the same way as Pp, K, aux1, and Pu are initialized outside of the loop.
They'd need to grow to a certain size first and even then, they could just hire remotely.
My hope is that these rules will only apply to large multinationals but somehow I doubt it - governments are unlikely to leave money on the table and will likely use this opportunity to expand the scope to include smaller businesses as well.
