My understanding is that crushed rock is inferior, as it binds too much water that weakens the concrete.

I'm pretty sure this is going to depend on what kind of rock it is, and how it was crushed and screened.

The storage just bought the farm, EIEIO.

PoE devices needs an isolation transformer in order to be compliant, and it takes quite some real estate. However, so does 110V/220V, but i guess we're so used to "hiding" it in a wall-wart.

Does this glass need a power supply, or do two ir photons join to make a visible photon? A reverse of scintillation?

It's using upconversion so it's 'powered' by the shorter wavelength light shining onto it

Hm, I've some problems with nix and desktop apps that needs opengl or similar machine-specific libraries. There are some hacks, and I also think nix comes very close to a good solution, but it's not 100% yet.

That’s mostly due to video drivers not being under nix’s control deliberately (if packages would depend on them as well, instead of a stub, there would be exponentially more build for each driver). On nixos this is solved by a specifically-placed stub, while it will be distro specific elsewhere, so it may not work for a random distro (that’s where “hacks” come into the picture, choosing a non-nixos distro specific lib as the stub and it will work just fine)

Mobile BankID is running in the sim card, and transfers fine to new phones. Except the ones with embedded sims, i guess :/

My (Swedish) BankID definitely doesn't run from the sim card. :S I've had 4 phones in Sweden and I had to enroll it as a new device each time in Nordea.

For radon, we installed a suction fan inside our house that sucks air from under the house. That lowers the pressure under the house, and radon doesn't seep in. It made the measurements go from ~120bq to 20bq.

Sorts as almost last in Norwegian and Danish locale. (aa=å)

That’s counterintuitive

Shameless plug: We're making good software defined cameras at huddly.com. "Plain" uvc, so it works on your favorite os.

But the bank now owes you $1000 and your fried $99000.
