My guess is that it gets released into the district heat grid during times of high demand, as heat. Converting the 450C heat to something around 100C for heating grid shouldn't be too difficult.

I'm struggling to figure out why/when would you reboot/powecycle a dumb switch?

checkmk mostly for show.
Self written pinger thing for purpose of auto-prodding humanoids if quality degrades or things disappear. Also throws FCS stats into a page sized overview. Army of various long running tcpdump and tshark capture filters to catch misbehaving devices and hu-mans.

I don't think any Google Android device has ever had microsd support. Ever.

Ainakin mercusys mesh laitteissa softa tuntui hyvin erilaiselta, ei lΓΆytynyt www pohjaista hallintaa ollenkaan, ainoastaan Γ€ppi.

Yeah you need padding. The best padding is random data, but it's hard for computers to generate random. Luckily you can get premade random bits, look for The Marsaglia Random Number CDROMs. You'll need about 200 of them to get enough padding though.

Typically in Nordics most people set the temperature they want, for example 21C, and then never touch it again.
A minority might have timer schedule with lower temps during the night. A small minority might have automation to adjust temperature up/down a couple of degrees based on electricity price.

Barriers exist already. In the US it's mandatory for producers to wash the eggs, in the EU it's forbidden to wash the eggs. Of course, you could wash them if they're going to the US, but hardly anyone has the facilities to do so. Egg crisis is temporary, so makes no sense investing in washers.

So then the government would own big parts of the biggest companies, since a tax ln wealth means transfer of ownership to the government. Nothing wrong with that in itself, as long as there's competent politicians managing these companies.

I tried to print a page last week. Suddenly windows claims printer is missing drivers. How?! It had drivers the week before.
If Microsoft is so keen on pushing OneDrive everywhere, couldn't they start with more important things like backing up drivers to OneDrive so I could get them back

AC transmission lines aren't really controllable. DC links can be steered with computer clicks.

At one point I thought it would be nice if I could turn on the dryer with my phone. But I realized that's just because the dryer doesn't make clothes dry on the first go.

As a network person I've had to find and show the O(n^2) in the code before the developers stopped blaming the network.

I thought I'd outsmart the "trying to take off" syndrome by switching from an i7 laptop to a "Pentium Silver" thing. Low power, low noise, right? No such luck, the manufacturer had removed all the fins from the heatsink, so fan goes into tornado mode to update the location of the mouse pointer.

Got an ancient D-Link that provides console through a web page with a java applet. Only works in IE on XP or older. Despite working in a hot and dusty environment, it refuses to die.

Finland, 2000, per-building primary heating system:
Electric: 35%
Oil or gas: 24,7%
Wood or peat: 23%
District heat: 10%
Coal or coke: 0,3%
Ground source heatpump: 0,3%
Other, unknown, or none: 6,7%
(District heat would dominate if stats were per heated cubic metres)

My idea of a "smart" dryer would be that the clothes come out dry regardless if it's a thick jacket or thin cotton cloth.
My idea of "smart" washer is that stuff gets clean, and that it gets the soap out when rinsing.

Something like this? 4+ km deep boreholes, but they couldn't make it work.

The increased efficiency of air source has made geothermal less interesting. For citywide you need massive amount of wells, or really really deep ones, which are difficult and expensive to drill.

They "sell" all of their electricity at cost to their multitude of owners, all of which likely have their own strategy for what happens with that electricity.
