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.

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.

Ainakin mercusys mesh laitteissa softa tuntui hyvin erilaiselta, ei löytynyt www pohjaista hallintaa ollenkaan, ainoastaan äppi.
Ovatkohan sitten kaikki uudet TP-Link kamakin nykyään ainoastaan äppihallittavia?

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.

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.
