In my past experience, any decently long lived bit of software (i.e. 5-10 years) goes through migrations to at least 2 different database engines (Usually as part of various other migrations like on-prem->cloud, or due to some licensing/$ reason) over its lifespan. And when you do it does tend to be quite a bit of work.
Get a copy of the Open University (UK distance learning uni, been around since the 70s) books on EBay.
A full set of books for MU123 (The most basic maths course, basically school [age 16] level books) can be had for under £50 on Ebay. Work through them, then move on to the MST124 books which are college [age 18] level), and are also widely available on EBay. Those begin to cover cover calculus, vectors, etc...
I'm 1/3 of the way through doing a maths degree with them, having scraped a C at school almost 20 years ago.
Yeah, we used Hetzner in Germany a lot at a former workplace where I was for a number of years, for production traffic, and we had a good experience. Most of our other infra was in physical DCs we owned, but we used Hetzner for production DR for the EU region, and also for internal stuff like CI/CD. Was slightly more reliable than AWS was at the time (2011-2014ish) , if I recall!
Other than some occasional small restaurants/pubs, and a few small indie shops, its basically accepted everywhere here in Edinburgh, I have a corporate amex and use it for expensing business dinners very often, and supplies from office shops, supermarkets, etc..
Quite the opposite in the UK, at least over the last 10 years or so.
99% of debit cards are Visa, and most people buying stuff on Amazon would be using a debit card, folks only really use credit cards for large purchases and things like travel, here.
Even when it comes to credit cards, I would say Mastercard has like a large chunk - like 80% in terms of institutions (but who knows in terms of actual customers), I would say.
Barclays and HSBC are the only majors that do Visa as far as I know. And Vanquis which is a junky one for people with bad credit.
The other majors like Lloyds, TSB, Bank Of Scotland, Halifax, Natwest, RBS, are all Mastercard. Same with most smaller banks like Virgin and CapitalOne, and store branded ones like Sainsburys/M&S/Tesco, too, as well as the remainder of the popular bad-credit cards like Ocean, and Aqua. Mastercard.
If you are wearing a suit, a smartphone makes the trouser pockets bulge a lot, so it's common to keep it in your shirt pocket or jacket inside pocket - Both of which is next to your heart.
> Taking your beautiful game that you've spend 5+ years on building and hacking it to pieces to run on older hardware
My understanding is that it was the other way around, which is why in my eyes there is no excuse for how badly it runs - It wasn't a case of adding support for older consoles at some point in development, rather, the PS5 etc... didn't exist (even as a spec) when they first started development of Cyberpunk, and as far as I had heard, they actually added support for next-gen something like halfway through development. They had no idea really of when the next gen consoles were going to release when they started it.
eInk would be a poor choice, the flash caused by updating the screen, every time you type a character, would be extremely fatiguing.
This refresh would be very very slow on a decent size screen which would lead to a very noticable typing lag.
I imagine it would also cause rapid wear of the screen, too.
In the few cases of EInk screens being used for signage, they avoid having things like clocks on there, for that reason, and they structure the display so its actually built of many different panels, which can be refreshed individually.
We used Hetzner in Germany, when I worked for a startup a few years ago, for some stuff which was getting too expensive on AWS, and which had to be located in Europe for certain reasons. A lot cheaper and reliability was good. We had many tens of servers there, at one point, at least.
Same goes for java app containers.
