Cold soda holds on to carbonation better. Try keeping it in the fridge before pouring. This also reduces how much the ice waters down your soda

Cartels have boats, but no one's shipping drugs up to Canada just to smuggle them south: They just get shipped directly to the US

Trump is just making up an excuse to justify cutting off trade with Canada.

Really, the whole fentanyl thing seems like scaremongering: People do overdose on it, but you won't die from touching it or inhaling trace quantity. It's not even the most potent opioid known, not even close to it.

Basically, chinese Instagram, that a lot of people are joining in protest to the incoming TikTok ban.

Assuming this has a 47 hydrogens stuck on to make it stable, I'd call it:

3-methyl-3,4,5,5,6-pentaethyl-6-buta-2-yl decane

Sounds like a great reason not to bother worrying about it to me.

It's a transistor, for switching parts on or off. It's either for a feature your not using, or in parallel with the other 3 for extra current capacity. In the second case it's possible it breaks in the future, perhaps try checking if they get hot when it's running.

That just pushes the heat production down the chain: Take a light: it converts electricity into electromagnetic waves. Those waves the get converted into heat when they hit things.

Perhaps feed the convincing fake data so they don't realize they've been IP banned/used agent filtered.

Not directly. That electricity is converted to heat when it's used: All devices are space heaters, some just do other things as well. Even if not used, it would still be converted to heat by the panels. There's no getting around the conservation of energy.

In theory, we could send that power out into space as microwaves or light, but in practice the effect would be negligible. The direct heat output of every human activity is nothing compared to the sun: All the electricity generated on earth is around 3 Terrawatts, while the sun hits us with 200 Pettawatts, 66 thousand times more.

On the other hand, burning fuels releases gasses like CO2, which can traps sunlight and creates thousands of times more heat than the actual amount of power generated. If we stopped burning fuel, it would stop the current massive increase in global temperature, which would then slowly be reversed by things like the carbonate-silicate cycle.

Other side:

Schematic:

 

Graphite is normally very soft and slippery, and is even able to act as a dry lubricant when finely powdered, however many sources claim that graphite powder can be highly abrasive, to the point of potentially destroying milling machines. Does anyone know how such a soft material can abrade metals?

 

A simulation based on maxwell's equations and ohms law of a very long circuit, demonstrating how current can seem to travel faster then light.

This is actually the exact same effect as the characteristic impedance of a transmission line, while pulse is traveling down it, the transmission line will appere to have a particular impedance, regardless of what is on the other end.

 

I am not familiar with the legal situation this instance's server and owner is in, are there any actions a user could take that could expose the operators to legal liability? Could the instance face problems if someone posts a link to pirated content? What about general discussion of piracy? Or any other possibly legally problematic content?

 

More 2d simulations of Maxwell's equations, this time demonstrating 2 mechanisms of dispertion in a waveguide.

 

RF Electronics (rfelectronics:discuss.tchncs.de) - a place to discuss the design, implementation, construction, and use of electronics operating at radio freqencies.

 

Not exactly useful as the simulation is 2d, but cool.
