Wait until they hear about nuclear powerplants and similar things still working on PDP-11s.
I have a client who has a very very specialised radiation therapy device that works with a very antique iteration of Unix. Its software has been reviewed thousands of times over the years and so has the operating system. They have plenty of spare parts and both the software and OS have been custom updated to work with 32-bit hardware over a decade ago as a precaution,but no hardware replacement has been needed so far - probably due to the relatively good protection from background radiation and very well done temperature management.
Should they upgrade to a modern OS just for the sake of being “up to date”? Fuck no.
That would mean:
-
Getting a new OS that is providing either drivers for the old hardware or getting new hardware. (Replacement costs for new hardware is around 20 million euro +X)
-
Additionally it would mean the new hardware or the new OS will be regulated under the new MDR regulation of the EU, so you can easily add another 20 Million (at least) just for that.
-
Additionally they would have to redo the complete radiation safety certification to prove that the OS does not accidentally fuck with the therapy. (See Therac-25 for that)
-
And the benefit. Minimal. The system is not connected to any network. While in theory an updated hardware could provide some minor advantages, e.g. using the patients data from the hospital information system or storing treatment data in there directly (it’s currently being done with a printer emulator), the therapy planning itself would not change as the very special circumstances this device is used for has only a limited range of treatment options.
So. Is it bad that this is not updated? Fuck no.
Cooking at home. The wife cooks “everyday” meals because somehow she is much faster than I am, I cook for special occasions (e.g. when we have guests),but she became so good over the years she also does that often.
We rarely (like twice a year) use convenience food due to allergies and quality and most of the time cook “from zero”, so that’s a bit more time consuming but still manageable.
Mealie or Tandoor help a lot here, as you can better plan your cooking and build a menu for the week. (E.g. “If I do this on Monday, I have ingredients B and broth left over/can easily do more so I will do something with B on Tuesday and Soup on Wednesday. Oh, when I do noodles for soup I can also do a bit more and make pasta for Thursday”) Additionally it makes it easier to adapt new recipes - we do various European dishes,from Portugal to Romania, some African and Arabian ones, some Indian, some South-East Asian ones and some Japanese and a lot of Korean ones. (We both lived abroad for a long time when we were younger). Especially for these rather “unusual” dishes planning is required as we sometimes need to order things online. (As getting some things is hard in rural central Europe). Grocy helps with that.
Delivery or Take Away is a rare choice,not only because it’s often inferior quality, it’s also fucking expensive. I can literally cook for a workweek for the money greek takeaway costs here. While we would have the financial means it’s simply, well, wasteful. In all aspects.
Eating out is something we rarely do. We both do have probably four times the “eating out” occasions due to our jobs than private ones. But when we do it, we plan it very carefully. It can be everything from a “hole-in-the-wall” in a sketchy backyard to a Michelin three star restaurant,but when we do it, it’s never out of “we are hungry, let’s go” and more a “we are interested in this and this, let’s find a restaurant that serves this.”(E.g. the last time we went out it was a Persian/Iranian restaurant that various Persian/Iranian friends recommended. It was absolutely worth it)
The funny side effect? The kiddo(s) have been to three Michelin star restaurants before they were three. They know how to behave in a restaurant. They only sometimes used to get angry when someone handed them the kids menu. K1 cooks African, Georgian, Romanian, etc. dishes on the same level as my wife and went to shop alone at the African store in town when they cooked for us. Which is run by a few very scary looking (but in reality very nice and very correct - they saved two girls from sexual assault a few years ago) Nigerian dudes that half the town js scared off. They drag their grandparents - which on one side were born behind the iron curtain and rarely eat out- into hole-in-the-wall backalley restaurants in Berlin, etc. This is one of the achievements I am really proud of.
People: Learn to cook. Seriously.
