grepular··on Syncthing: A continuous file synchronization program
I use it to store most of my private git repos and have been doing so for years now without a single issue. I do this:

    cd ~/Sync/git
    mkdir reponame
    cd reponame
    git init --bare
    cd ~/work
    git clone ~/Sync/git/reponame
I guess this could break if I do a push and then shut my laptop lid before it syncs, and then do some more work on my desktop, push, and then go back to my laptop. That hasn't happened though. If it did, it should be trivial to fix.

There was some other comment near here about ignoring .git directories. I guess they're using it to store the working directory rather than just the repository, as there is no .git directory stored in ~/Sync/ in my situation.

If you're going to attack the idea, at least address the bits of the page that talk about the thing you think doesn't work:

> Even in northern countries like The Netherlands the sun gives enough energy for average urban use. The solar panel can charge up to 20 km per day in Europe. The average micro car usage is around 12 km per day.

From the FAQ on the trial page, it seems like it will simply not run if there is nowhere to dump the excess heat:

How much of my hot water will it deliver?

A useful base load. If the heata unit ran all day it would deliver about 4.8kWh of hot water which is about the amount of hot water an average household uses. In practice the utilisation level will be lower and sometimes the water will be at temperature so the heata unit won't be able to run. We think it could deliver up to 80% of an average household's hot water, with good compute utilisation. This trial will help us learn more about how this will work in practice and enable us to give you a useful amount of free hot water at the same time.

They're not running it off 4G. Click through to the trial and read the FAQ. It's using your home broadband connection.
grepular··on Install a server in your house, get free hot water!
Some jobs require a large amount of cpu and a small amount of data. I imagine that is what this system is for.

Ultimately, it will be costing them money to create this hardware, install it in your house, and then pay you for the electricity it uses. It seems likely to me that they'll have considered a way of making money from it.

[edit] I investigated further and one of the things they do on these machines is 3D rendering.

> Wouldn't this destroy my upload speed?

They specifically say that they run speed tests and then restrict their usage to a fraction of your speed. So no.

> Isn't running a regular server (not home media server) rate limited/outright banned in the TOS of most home internet service providers?

Don't think of it as a server. Think of it as a PC that is running all the time. These TOS you're thinking of are usually to prevent you running services that can be connected to like web servers and smtp servers. For all we know, this machine doesn't listen for incoming connections and just makes outgoing connections. Just like your phones browser is doing. Your phone isn't a server banned by your ISP's TOS is it?

> How useful is a compute node that can't use the internet

It doesn't say that. It says that it will use your broadband connection. It says most of the time it will just be for monitoring and speed tests, and it also says that larger uploads/downloads will be limited to a fraction of your bandwidth and they'll try to run it overnight.

To me, this says they'll send/retrieve datasets to be processed on the server, slowly, mostly overnight.

> It is in direct contradiction to what the author of the article wrote

Yes. I don't know why he wrote it, but if you click through to the trial on https://www.heata.co/trial and scroll down to the FAQ, it is right there.

> And if it does use the internet, it's now using your internet (and presumably your electricity) for free

I think maybe you need to read the FAQ. They see how much electricity they're using by installing a meter for this specific purpose, and they pay you for it.

I clicked through to the trial and in the FAQ it says:

Will you use my broadband?

Yes, we will connect to your broadband to communicate with the units. We'll directly connect to your router to avoid WiFi interference and most of the time the unit will simply be sending some monitoring information (temperatures / fan speeds etc) back to base, so you shouldn't notice any impact. We'll occasionally perform speed tests, and limit any larger uploads and downloads to a fraction of this so we'll never use too much of your bandwidth. We'll also schedule these overnight so it shouldn't affect your daytime speeds. Our intention is that you won't notice - one of the things we'll be doing during the trial is getting your feedback on if we've achieved this. In the future we plan to install a dedicated fibre or 4G/5G connection for the heata unit.

It should be based on households rather than population. There were 24,782,800 households in England and Wales on the last Census Day in 2021. Meaning by your other figures/logic, you have a 62% chance of being burgled at some point if you live in England or Wales. I.e, you're more likely to get burgled than not.
grepular··on Matter – Protocol to connect compatible devices and systems with one another
I plugged my dumb washing machine, dishwasher and tumble dryer into some zwave plugs which can report on energy draw. Hooked it up to Home Assistant, which is hooked up to Alexa. Now whenever any of my dumb washing machine, dishwasher or tumble dryer finish a run, it announces through my echo dot that it has finished. This is pretty useful to us as the washing machine and tumble dryer are in the garage, and the dishwasher finished beep is pretty quiet.

I do kind of the same in Firefox with ublock origin, making it permanent. "Right click", Block Element". I also added a userContent.css file to my firefox profile, which adds the following style to every page on every website, so I don't have to deal with the overflow shite:

I had one on pre-order. There were multiple delays even before the pandemic started. The first delay when the pandemic started was the last straw for me and I got myself a refund.

I'm willing to make a lot of sacrifices for a phone like this, but I'm not willing to sacrifice charging my phone whilst I sleep and then being confident it will work all day.

This could be the greatest phone ever made, but if it doesn't last a full day, it's worse than every other phone I've owned, or will own.
