I have tested this and they are very capable, replacing the modern windows calc (38mb mem) with an identical app (ux, looks, features, accessibility, localization) ended up with an app using 2MB memory.
You just need to point it in the right direction (c/rust/go etc) and be harsh with the requirements, especially memory usage.
If I was Microsoft I would use AI for this rather than badly embedding AI everywhere, a lot of power users would be overwhelmed by a win 11 update where OS apps/features dropped mem usage by 90%+
They kind do if you prompt them, I had mine reimplement the Windows calc (almost fully feature complete) in rust running with 2mb RAM instead of 40mb or whatever the win 11 version uses as a POC.
A handwritten c implementation would most likely be better, but there is so much to gain from just slaughtering the abstraction bloat it does not really matter.
Last maintenance I did on my Volvo was to replace the battery which should be quick for a non-mechanic as myself.
I spent more time building a make shift tool to detach/attach the battery than I did actual work. This due to them placing a bolt really bad so you can't access it with a normal wrench.
Not offering a paid upgrade to a 4G modem for the app features when they kill the 3G network in Sweden is also a bummer (they do in the US though, guess they are afraid of law suits).
I like the car in general, but they do some bad decisions that make me look at other brands when considering a new car.
Did a similar thing when we needed to do complex operations towards aws.
Instead of wrapping the aws cli command I wrote small Go applications using the boto3 library.
Removed the headaches when passing in complex params, parsing output and and also made the logic portable as we need to do the builds on different platforms (Windows, Linux and macOS).
The last part missing is "build a flawed product and bake it into the contract so you charge high consultant costs to the customer to fix it" which is where the cash cow is for many enterprise / B2G products.
I would like to say thank you for posting this, I am currently building a similar toolkit in Lua and will most likely restart and just port your code instead :)
I am thinking of the more basic air/air units rather than this air/water.
One well placed air/air can reduce the need for direct electricity heating a lot, even though some might be needed to assist in a bedroom or so.
My parents installed a air/air unit in the middle of the house (180kvm) for $2.5k this summer and it keeps the whole house heated except one bedroom that needs some assistance from a radiator.
On the topic there are a category of preschools in Sweden called "Ur och skur" which have most education outdoors.
Back in the 90s I know some primary schools in Sweden also had education outside, but I think that have changed with schools becoming more competitive lately.
I had an idea for a similar project (1) a few years back, but abandoned it after reaching the state where I had a node module to attach an Electron window to the wallpaper in Windows.
Fun to see a project that has reached further, remember how cool I used to think dashboards/widgets for the PC stats were when I was younger.
In Sweden most government data is public which includes individuals tax records.
That generates things such as news articles "The 50 people in your area that had the highest income last year" with home address and everything and that you can look up income instantly on the web.
Some level of privacy for this would be nice to have.
I can also strongly recommend Gandi. Used them to manage 40+ domains for my old company. Professional and good coverage of the TLDs.
Nice is also that you can buy credits - that way I could renew a bunch of domains that expired at different times and filing only invoice to bookkeeping.
