Re:Coffee grounds make concrete 30% stronger on Wednesday August 23, 2023 @12:30PM (#37238514)
My understanding is that crushed rock is inferior, as it binds too much water that weakens the concrete.

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?

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

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.
Re:Is there hope for IPv6? on Saturday January 05, 2019 @11:30AM (#18832447)
We tried setting up automatic DNS records on dhcpv6 and slaac on our company lan, and we just weren't able (opnsense). We have ipv6 working, but it still doesn't "feel finished".
I don't have the source right now, but I think you are more likely to spread germs when you fiddle with your mask.
Actually, they need bigger fans there because of the thinner air (high elevation).
On packed snow like that, you can even have an angle > 90 deg.
Re:Norway to become first country to switch off FM radio on Friday January 06, 2017 @06:53AM (#13335621)
It's because the infrastructure for FM is quite expensive to run. Because of all the fjords and valleys, you need many weak transmitters to avoid reflections. Also, because it's FM, they can't overlap in frequency.

With DAB, two time-delayed signals (either reflections or multiple towers transmitting the same data-fountain) will enhance the signal. This means that you can have fewer towers.

Re:Huge home-built computer used for Tetris on Tuesday July 05, 2016 @09:44AM (#12036355)
Nice. This also reflects my experience that the connectors often are the most expensive electronic parts :)
If you know how, please do tell or provide some pointers. It would be nice to set up at my site.

I'm not so sure. Primitive mining in e.g. Røros, Norway goes back to 1740. Dynamite were introduced to the mine in 1870. https://en.wikipedia.org/wiki/R%C3%B8ros
Re:Hidden motors for road bikes on Tuesday March 08, 2016 @03:03PM (#11248096)
I think the current case where an athlete (Femke Van den Driessche) is caught with "bike doping", she was caught by "scanning" her bicycle with a smartphone, using the compass to detect the permamagnets in the motor.
Re:Microchip Technology to Buy Atmel for Nearly $3.6B on Thursday January 21, 2016 @03:05AM (#10943993)
I think AVR32 is dead (also UC3, AP7 died years ago). I've not seen any development the last years. I guess they don't want to compete with their own ARM's.

> if you ask 100 people if they are better than average drivers, then you might not be surprised if more than 50% of them reply “yes”!

Isn't it fully possible that most people are better than the average? Most people e.g. have more arms than average.
