Do they have safer behaviour when improperly manufactured, stored, handled and used?

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.

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

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.

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.

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.

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.

I'm curious about the root cause. Is it that elgato hasn't updated their software for newer computers?

It's worse with Teams when there's many mutually incompatible versions of it. I was recently in a teams meeting where half the attendees vanished halfway through because they had to update Teams and it lost mic and cams for many.

In the early days (Roughly redhat 6 days, whenever that was) I got to use some unknown distro at Uni with Ximian Gnome, and it felt so useful and polished compared to plain unpaid redhat.

Since both floppy drive units went from working to dead, I always assumed it was the interface on the 8032, so I never tried printer again. Don't have copy of word processor on tape either :-(

Didn't find anything in the yellow pages, and I didn't have a modem for the PET so I couldn't ask internet (well, BBS message groups would've been more realistic) for tips.

I have a setup similar to that in storage. Except it's a 8032, and neither the 8050 nor 4040 drives worked the last time I checked (2005), and the printer ribbon is out of ink. Around 1995 or so I made my own word processor which printed every line 3 times to compensate dwindling ink.

When I saw the light bulb picture, I did wonder if the article would be about how the amount of money (as a proportion of GDP) spent on lighting has remained fairly constant, we just use a lot more light as it gets cheaper.

Lack of gas network: yes Instead heating oil used to be very lightly taxed compared to motor fuels. In Finland there was a recent short lived subsidy for getting rid of oil boilers at the same time as the levy on heating oil was raised. Effects probably not visible in stats yet.

it means electric tech caught up with computer technology. "Have you tried turning it off and then back on again" now also applies to breakers. 😂

(also electrician) this also means sometimes you can have a tripped breaker without it showing.
