In the moment, yes.

However, the longevity of digital data is problematic. Computers have existed for less then a 100 years, but you'd already be hard pressed to read the data off a deck of punch cards or reel of magnetic tape.

Modern protocols and formats are much more complex, so I'd say that reading your data in 100 years will be harder then reading 100 year old data today. Have a look at a pdf in a text editor. Imagine trying to figure that out once the documentation is lost. (... or stored in the pdf)

Without continual efforts to convert data or preserve hardware and software, the data will be lost.

Compare that to written documents. We have writing that's thousands of years old, and it's still legible and understandable. We have paper documents about as old as we've been able to make the stuff.

Unfortunately, physics comes in and ruins your plan: https://en.wikipedia.org/wiki/Etendue

Your focal point will never be brighter then the firefly itself: https://what-if.xkcd.com/145/ (at least for diffuse light something sources that emit in all directions)

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.

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.
