If something is Nuclear enough it can generate heat
That’s an extreme oversimplification. RTGs don’t use nuclear waste. Spent reactor fuel still emits a large amount of gamma and neutron radiation, but not with enough intensity to be useful in a reactor. The amount of shielding required makes any kind of non-terrestrial application impossible.
The most common RTG fuel is ^238^Pu, which emits mostly alpha and beta particles, and can be used with minimal shielding. It can’t be produced by reprocessing spent reactor fuel. In 2024, only Russia is manufacturing it.
^90^Sr can be extracted from nuclear fuel, and was used by early Soviet RTGs, but only terrestrially because the gamma emission requires heavy shielding. Strontium is also a very reactive alkaline metal. It isn’t used as RTG fuel today.

the waste it produces is highly problematic.

Others have answered, but I’ll say it anyway.
Paracetamol is used in most of the world, and by the WHO. Acetaminophen is the adopted name in the United States, Canada, and Japan. US pharmacies also use APAP. The most common trade names are Tylenol and Panadol. They all refer to the same stuff.

Regular use also fucks up your organs. Paracetamol (Tylenol) kills your liver, and ibuprofen kills your kidneys.

Windows search bar
I’m baffled that people actually have the news on the taskbar. It’s the first thing I kill on every install (not that I use Windows, but sometimes I need it in a VM).

- Comment on Why do different ethnicities/races look different? 1 week ago:
Elephants. African elephants have large ears to assist in maintaining their body temperature. Asian elephants that migrated farther north evolved smaller ears because the evolutionary pressure wasn’t as significant.

It makes sense if you represent complex numbers as
(a, b)pairs, whereais the real part andbis the imaginary part (just like the populara + birepresentation). AB’s length is(1, 0), AC’s length is(0, 1), and BC’s length will also be a complex number. - Comment on Why are laptop adapters so much larger than phone adapters of same power rating? 2 weeks ago:
USB Power Delivery over a regular USB-C-compliant cable delivers a variable current of up to 3A, using discrete voltages of 5V for up to 15W of power, 9V for up to 27W, 12V for up to 48W, and 20V for up to 60W.
Higher powers require dedicated USB PD-compliant cables that can handle up to 240W at a voltage of 48V.
- Comment on Why are laptop adapters so much larger than phone adapters of same power rating? 2 weeks ago:
My uneducated guess is money.
Manufacturers likely have factories (either theirs or a contracted company’s) where they can mass produce the power bricks for a low cost. Upgrading to a USB power supply doesn’t offer significant benefits compared to the power brick of similar wattage, and the up-front cost of setting up a new supplier is financially unjustified. The old technology works just as well, so why change?
High power USB is still a relatively new technology. I’m sure it will proliferate, but the consumer market has a fuckton of inertia.

What a way to put on the appearance of an enlightened neutral observer while completely ignoring the complex socio-political situation by reducing it to a simple, sweeping statement. Couldn’t have done it better myself.

Adherence to a moral standard is secular, even if the source is a text of religious significance.

In terms of religion, atheist. Adherence to a moral standard is secular and does not require a supreme being.

- Comment on Why are people impressed with SpaceX? 4 weeks ago:
Yep. It’s called a sounding rocket. Jeff Bezos and his dick-shaped sounding rocket.
If he ever gets two vehicles into orbit and makes them dock together, the mental image might just be enough to kill me.
- Comment on Why are people impressed with SpaceX? 4 weeks ago:
Rapidly reusable orbital launch vehicles were unheard-of until Falcon 9. The Space Shuttle was supposed to fill that role, but NASA, ULA, and government elements have made it a horrid overbuilt pile of feature creep that was, at the same time, the crowning achievement of American aeronautical engineering. The same thing that is currently happening to SLS.
Propulsive landing of a first stage booster was an insane idea. Even massive space nerds like Everyday Astronaut were skeptical, and I watched him cream his jeans live when the first booster landed. That alone, the ability to reuse both the structure and the engines of the booster, as opposed to ditching them in the ocean (or in China’s case, on top of villages), has made access to low Earth orbit significantly cheaper, and affordable to underfunded scientific organizations.
