Adderall is just regular amphetamine, not even a substituted amphetamine.

I think houseplants will like horticultural LEDs much more than high-CRI lights.

In many cases you can break one of the resistors off the LED bulb's printed-circuit board and run them at two-thirds of the power so they last forever. In other cases the surgery required is a little more involved than just snapping a

The US and Russian Navies deciding to remain mostly petroleum-fueled is one of the strongest arguments against nuclear becoming very cheap: surely they would do it if it wasn't ruinously expensive, because it eliminates the national se

Solar panels do not become useless in 25 years and need to be discarded, do not leach toxic chemicals, and do not contain cadmium. They do contain small amounts of lead, but leaching metallic lead out of landfills is very difficult and pro

> Wind and solar existed in the 70s as well. This is basically nonsense to the extent that it is becoming difficult to extend the presumption of good faith to you. In the 70s solar panels cost US$25+ per peak watt, in 02021-adjusted d

Ground-source heat pumps are irrelevant to geothermal energy sources, and it's unfortunate that the article mentioned them. Ground-source heat pumps are just storing heat from the air during the summer and retrieving it during the win

While it's true that a geothermal plant is a limited battery powered by hot rock, that doesn't mean it doesn't make economic sense compared to other energy sources.

Yes, that's what this article is about.

I hadn't realized that the IDDP had hit magma! That's very exciting! Obviously I'm very out of date, since that was in 02008. However, I'm skeptical that geothermal energy can be economically competitive with solar wit

The solution I was taught as a child is to saw the hole square, put a section of 2×4 behind it spanning the hole, held in place with a drywall screw through the drywall on each side of the hole, cut a square chunk of drywall small enough to

Guess what, lots of people have been building GUI applications without views, much less view controllers, for longer than that. Including Squeak, with Morphic.

DNS postdated port numbers. Mockapetris's DNS RFCs are from 01983, although I think I've talked to people who installed DNS a year or two before that. Port numbers were first proposed in RFC 38 in 01970 https://datatra

The nature of the output displayed EQUIVOCAL HERESIARCH TAMP THE PRESBYOPIA STYPTIC ILLUSION ABSORB THE EIDOLA makes me think that it's a sort of mad-libs phrase generator. The leading adjective "PENSILE" appear

Packet switching is cheaper; even though it can't make any guarantees about latency and bandwidth the way circuit switching could, it uses scarce long-haul bandwidth more efficiently. I regularly see people falling off video calls,

Does "session protocol" mean that it provided packet retransmission and reordering, like TCP? How does that save you serializing and deserializing byte streams? I agree that, given the existing design of IP and TCP, you could get

METAFONT in particular does not have a way to write code to produce different random variations for the same glyph, nor does its output format have a way to encode those multiple alternatives in its output. I'm not sure if PostScript

The WebMD page is about calomel, mercuric chloride, and perchloride of mercury, not metallic mercury; the body text is clear about this, but the title is wrong. It describes all kinds of poisoning symptoms that don't occur with metall

You could probably add enough phosphate to all your food to prevent you from absorbing any manganese, then inject iron, calcium, and magnesium? Just guessing here. How long would it take you to die on a zero-manganese diet? If it's l
