I have been self-hosting for about 25 years.
I remember the protection.outlook.com issue.
Once there was an issue with a bank that tried to do encryption, but used an expired certificate. But once I told them what the problem was, and that it was a problem for paying customers, they actually fixed it.
Being able to check the server log can be very useful. E.g. to tell someone that their mail was delivered to a served using their domain name, with that IP-address at that time.
But smartphone cameras are not progress on all fronts.
They are small and seem to be optimized to take pictures that look impressive.
I sometimes have a slideshow with family pictures running on a large monitor.
Sometimes I stop and look at a picture that somehow just look much nicer that the rest when you spend some time looking at it. If I then check the metadata, it almost always turns out to be one of few pictures I took with my old DSLR camera or a newer compact camera.
Of course those cameras are much bigger and has bigger lenses and should be able to make better pictures. But the best camera is the one you brought with you. Which is why so few of the pictures are made with a smartphone.
But it seems to me that all the computational power of smartphones does not quite compensate for the smaller optics. Or that they are trying too hard to make the pictures look spectacular.
The only time that matters is whatever the clock in the clubhouse shows (Danish time)
If you sign out a boat from the UK (or more realistically from a laptop that thinks it is in the UK) at 14:00 it is still 14:00 Danish time. This is surprisingly difficult to achieve with JS Date object, browsers and popular JS components.
So the Temporal Plain time looks promising.
And especially the explicit timezones. Because even without timezone you need to handle DST.
For example my system needs to know that if you start a 3 hour trip at midnight a certain day in the spring, you are expected back at 04:00.
I just hope that browsers and components will support is properly.
Heat pumps have thermostats so they do not run at max all the time.
So if the heat pump without the miner use 1 kW to heat to room temperature it would need less than 1 kW with the miner to heat to the same room temperature. Plus as you say the COP increases.
So it could be that 5 degC to 22 degC requires 3 kW but the heat pump can do it with 1 kW (COP=3).
The miner use 0.9 kW to heat the the outside air to 11 degC. It would take 2.1 Kw to heat from that to 22 degC. But the heat pump now has a COP of 4 so it can do it with 0.5 kW.
So you lose 0.4 kW but gain bitcoins.
Or you could say that you get 2.25 as many BTC for the same electricity cost.
So today there are 243 restaurants, cafes and fast food places in OSM that do not have a valid inspection report (the pink ones on my map). I think that many are just closed temporarily because of Covid and therefore have not been inspected and the inspection report just timed out. Probably some that have an inspection report will never open again, but I will soon find out.
Many of them are cafeterias for employees in larger companies and will likely open again.
Many restaurants are open for takeaway, also many that did not do takeaway before the lockdown.
I have lately been doing speedlimits, mostly from Mapillary. But I have also done some surveying on bicycle.
Yes, we could use some numbers here.
I.e., how much energy would it take to grow one kg of potatoes in artificial lighting. Compared to how much it takes to transport it by ship from Morocco to Copenhagen. Or by an electrical train from Spain.
Production of electricity from wind turbines fluctuates a lot. So does the price. I wonder if there are plants that you can give light when it is windy at any time of the day and leave in the dark when when electricity is expensive.
Not really.
With git bisect you know what you are looking for.
So even if you did make a commit with e.g., a missing semicolon you can still call it "good" because it did not cause the problem your are trying to debug.
