  • Fyi the syncthing-fork guy (catfriend1) who’s still updating has a donating button on F-droid via Liberapay. It’s up to you if your financial situation allows you to donate, but the more of us help the remaining developers for their time, in particular those of us that rely so much on their work, the better off we’ll be. Let’s give them a little motivation to keep working on this.

    FYI2 syncthing-fork (as written and confirmed in this thread) has an import button for your folders from syncthing Android.



  • The math depends on where you’re living, but what would you mathematically compare here, available required roof area and roof load limits?

    Because the SWH, if put in a place like Cyprus, consumes next to no electricity. Pumps and electronics, but even that is pretty nil if the tank is on the upper floors. So let’s assume a mild sunny climate where the electrical heaters of both the heat pump and the solar heater are off. The heat pump requires power and the water heater doesn’t. As for cloudy days, with proper insulation, a SWH can keep the tank piping hot for a few days.

    Personally i don’t see how a heat pump could beat a SWH in costs and benefits over time. Off the gate it already starts at a disadvantage on environmental impact and upfront costs. When it’s sunny, it loses to solar heating, as it’s free vs very efficient. It probably regains some ground during inclement weather and very cold winter days. There’s also the degradation of the solar panel, which happens at a faster rate than the degradation of the solar heater. So i guess in the end it boils down to how bad the weather gets where you live and yeah, do the math. There’s probably a graph of bad weather days with a point where the SWH becomes less attractive than solar powered heat pumps. But for Mediterranean climates, no contest I’d say. You require less area on the roof for a SWH.

    And this is only considering available roof area/weight limits, because being honest they’re both free sun energy. But you could use the solar power/money/environmental impact elsewhere.


  • From the point of view of efficiency, solar heaters beat pv. With pv you need to convert the sun’s energy into electrical energy, with losses, then convert electrical energy into heat by extracting it from the outside with the heat pump. If you store it in batteries to heat up water later, there’s even more losses. Depending on the outside temperature, there’s a limit to what the heat pump can do, which an internal electric heater inside the water tank takes over to reach usable shower temperature.

    With solar heating the sun heats water, that’s it. Not only you can yield energy from the sun more efficiently, this doesn’t need complex electronics or semiconductors, so it’s also better from an environmental impact point of view.

    And it doesn’t have to be either/or. In my country, solar heating usually comes as a package deal with pv heating. Some companies are making hybrid pvs. Solar panels become less efficient as they heat up, so a hybrid pv would use coolant to keep them within their most efficient working temperature and extract that heat to be used for space heating, using radiators or floor heating or forced air systems, and/or water heating. Having both just makes sense, since it makes your pv needs (and your upfront investment) smaller and the maintenance on solar heaters is much simpler.




  • It might sound like a pretty obvious thing, but have you tried changing the tools into the “Tabbed ribbon” that office uses instead of the classic old 90s organization scheme in options ?

    I have come to notice that when people who don’t really work with computers very well, in particular boomers, say that they can’t stand LibreOffice, they mean they don’t like the layout of the tools, because they can’t find anything they need. I suppose they just got used to where everything is with modern office.

    Just change it and see if she will like it better. Usually solves it for the boomers i help. Nothing is holding LibreOffice back more than their default layout scheme. They really don’t know their target audience’s pain points AT ALL. Just goes to show why you need to study your users using the product without being explained anything.

    I don’t get why their default is a layout that has been outdated for 24 years. Nostalgia or what? Only really old people who used computers in the 90s a lot will intuitively find it useful.

    The survey fatigue is real. Everyone keeps begging for reviews nowadays. Even random things like public parking.

    I grow resentment at any business begging for reviews. Hire a consultant and third party to auction your service, I’m not doing it for free anymore. Specially because they don’t even read the comments you write or reply. It’s just nonsense an intern will put into an end of quarter ppt for some average mediocre manager.





  • I can guarantee you that is never going to happen. You ban VPNs and all the companies R&D departments will leave. A VPN is an essential part of corporate data infrastructure. If a company is unable to secure intellectual property, it will move it elsewhere, leaving only sales and manufacturing, at best.

    And since France is in Schengen, I’m sure other European countries would love to get those corporate taxes for themselves.
