  • Home ACs are just wasteful.

    I don’t know, ours eats 400-500W to cool the entire ground floor, which is a fraction of what the solar panels produce on a sunny day, and a fraction of the surplus energy we have no choice but to sell the utility company for a pittance.
    In spring and autumn it can also heat the inside and has a COP of between 4 and 5 then, so much more efficient than a regular electric heater and probably more environmentally friendly than if the central heating would burn more oil - the circulation pump alone uses close to 400W.

    Of course we could live without it (people have lived in the house without an A/C before), but it’s much more agreeable like this, not to mention that it allows us to use the winter garden as an office in summer, which has a great view over the garden and allows us to keep an eye on the dogs. There are many much less sensible ways to use that energy than the A/C.

    Back to the battery, some EVs can be used as battery storage (vehicle to house, vehicle to grid or vehicle to load). Maybe one of those would make it more viable to have both an EV and storage space for your harvested sun? Not mavy EVs can do it at present, but it may pay to keep an eye on new models.


  • I don’t know if you’ve already heard of them or if they’re even available where you live, but if it’s the cold air that bugs you, there are water-cooled ceiling plates that work just as well as a conventional A/C. An office I used to work at had them and they were lovely. They cost quite a bit more though.

    As an alternative if you just want to avoid feeding surplus energy into the grid, what about a battery of 5-20kWh? It could store more energy than the A/C uses during the day, probably costs about the same or less, and you can use that energy at night.


  • I’m not sure “cooling degree days” are a good way to measure environmental impact. They neither represent the amount of heat pumped into the atmosphere (as the energy per degree depends on several factors such as mass and heat capacity of the cooled stuff) nor the amount of electricity used (as different A/C’s have wildly different degrees of efficiency) nor the amount of CO2 released (as that depends on how the electricity has been produced).

    The power hunger of AI has already been mentioned, so I’m not going to repeat that point, though IMHO it’s by far the bigger issue than residential cooling.

    Having said that, if you’re worried about the enviromental impact of your home, the power consumption of a reasonably efficient A/C can easily be offset by just a couple of medium-sized solar panels. Of course both the solar panels and the efficient A/C cost money that not everybody can afford to (or cares to) spend, so you’d have to take cheap and inefficient A/C’s off the market, thus effectively making chilled air a privilege that only the rich can afford. That’d probably lead to lots of heat strokes and other health problems amongst low-income families, so you’d have to weigh the environmental impact of inefficient A/C’s against another rich/poor gap.



  • It depends on what you’re looking for.

    File storage - plenty of solutions, though make sure you don’t pick one that rents their storage space from AWS or Azure.
    Personally I use Tresorit at it is end-to-end encrypted, easy to use and has a native client for almost every system I use (except for FreeBSD) in addition to the web interface. On your PC you get a network drive but can also include folders located elsewhere. It’s by no means the cheapest solutio though.

    For pictures there’s Ente. It works very well, is cross-platform, and you can even set up your own server if you’re so inclined.

    Sadly there’s no real alternative to Microsoft’s 365 offers - maybe a combination of lifetime MS Office licences or LibreOffice plus some cloud storage provider comes close.

    To replace Teams you could use a secure messenger such as Threema Work (this version comes with user management and a versatile inbuilt MDM) and your own Jitsi videochat server. We’ve replaced Teams with this combo years ago and never looked back.

    Hosted Exchange can be rented from many service providers, running on either genuine MS Exchange or a compatible third-party system such as KerioConnect.

    There are also other places such as Proton that offer several services at once.

    Or are you looking for something completely different?






  • Yes, but every sensible person would likely be vaccinated*. Antivaxxers often get away with being unvaccinated just because of sheer dumb luck (they don’t get infected). A mass (self-)infection event could quickly rectify that situation.

    • Everybody with immuno deficiency would probably have to stay indoors for a couple of months, but all things considered I’d say that’d be a small price to pay if it means millions of antivaxxers and Trump supporters get to see the error of their ways or outright kill themselves.



  • FWIW, Android offers a one-handed mode to shrink the available screen estate so you can reach the top of the screen with your thumb. It needs to be enabled in settings once and can then be toggled by double-tapping the home button or a swiping gesture at the bottom of the screen.
    In my experience (6.1" Samsung Galaxy S2x user with slightly above-average hands) this is a good compromise between occasionally wanting to do things one-handed on the shrunken screen, and still being able to hit the right keys on the on-screen keyboard most of the time on the regular-size screen.

    Bing DuckDuckGo says the iPhone has a similar feature, though I haven’t touched one in years so can’t say anything about it.




  • That question is going to be impossible to answer without a lot more details. The number of websites is largely irrelevant (each website will use a negligible amount of RAM for the web server process to know about). What you want to know is the total number of HTTP and HTTPS requests per minute (the latter being a bit more expensive) in peak times to estimate the required CPU horsepower, the amount of data transferred (network bandwidth and CPU to some degree), whether it will be mostly static pages or dynamic/scripted content (CPU and RAM), and of course disk space to store everything (a stock photo library will likely use more space than a pizza place).
    If there’s a database backend you’ll want to add even more RAM and faster storage (both in terms of throughput and IOPS).
    Also, acceptable waiting times. An under-powered server will work just the same, just slower.

    If you know a bit about the websites you want to host but need some pointers, maybe start by checking out some packages by other hosting providers (how much CPU and RAM does their ‘local chess club WordPress site’ package offer?) and go from there.
