It's not "basically true" though. The whole point of the "disorder" designation is that it interferes with life activities. Everyone has attention deficits at times - that does not a disorder make. Otherwise I agree

You jest, but I believe some of these incidents have been caused by some sort of delay mechanism which gets stuck, until one day it is dug up or corrodes enough to unstick, at which point it goes off.

Thanks for the correction! Yeah, I did some more digging and there are in fact some wacky designs. The single-fusing-element is more dominant in modern designs, but war is a crazy place. (pdf warning) https://www.fh-campuswien.ac

> The bomb likely had another, undetected detonator That would be really poor bomb design. Bombs are designed to be stored inert near the airstrip, mounted to staged aircraft and armed quickly by inserting a primer/detonator. There

Some context as a chemist. Most explosives require DDT (deflagration to detonation transition) in order to explode. DDT occurs when the flame front goes supersonic in the material and creates a shockwave (simplification but close enough). L

Because it's almost always the case that the consumer is going to keep a reference to the task in some way, so that is the logical choice for the "primary owner" of the task. Python doesn't have ownership per se like rus

This is good form. It makes top-level control flow easier to follow, and keeps the concurrency scoped.

It's typical paper-thin plausible deniability of corporations justifying actions. - Oil supplies are tough so we are raising gas prices (we know we can get a few weeks/months of crazy profits and blame it on the energy crisis) - S

Doped strontium alluminate is not exactly food grade (though it is considered non-toxic), but that's not the orifice these devices are going in. The silicone matrix retains the vast majority of the pigment, which itself is fairly inert

United Nuclear is quite the nostalgia bomb. My first experience with them was in 2008, buying a chunk of uranium ore to trigger a geiger counter to use as a true random number generator. I'd say "where else can you just buy a chun

It's used in miniscule quantities in glow powder. It's commercial use as a pigment/phosphor in display, lighting, and safety equipment far outweighs its use by hobbyists.

Add it to anything you want to make glow-in-the-dark: paints, toys, safety equipment. I know someone who produces small batch silicone adult entertainment devices for sale, and the GITD ones are quite popular.

It's most likely the same chemical formula (so yes, "same stuff"), but phosphors vary quite a bit in their quality based on the synthesis conditions (maybe the "same stuff", or may be better/worse quality than

This completely misses the point of the entire article, which is by/for power lifter and bodybuilders. Obviously there is no way around "lift a heavy bar 3-4x a week." The whole discussion is about whether any of the folk-wis

Yes, steroids are technically illegal, but they are typically Sch 4, and are just about the "softest" kind of illegal. As in, it's pretty trivial to find vendor willing to ship you a kilo of "cellulose" or other pap

Actual chemist here: it's actually pretty hard to accidentally produce phosgene via chloroform. Obviously don't deliberately try to oxidize chloroform in an unventilated space, but you should be fine in a fume cupboard with basic

> The poor efficacy of DMSO in assisting drug translocation through skin Oh yeah, for the observer gallery: The reason DMSO (and DMF, DMAc, HF, to an extent haloforms, and polar aprotic solvents in general) are dangerous is that they can

I mean, pure DMSO on the skin feels fine, albeit not the safest.

More or less, but with caveats. It's true that many smells (eg H2S, HCN) are detectable before toxic levels, and then become un-smellable at higher levels (saturates and depletes olfactory receptors). But you should still worry about c

I'm a bit rusty (worked as a chemist 2011-2015 before going into compsci) but I believe that this reaction produces some chloroform (enough that you should not mix ethanol and bleach inadvertently), but mostly as a side-reaction. The m

Ether and chloroform both have relatively narrow therapeutic windows - the toxic dose is very close to the minimum active dose. But they were one of the few true anaesthetics at the time (late 1800s). Alcohol was also used for surgery but i

There's only one thing on that list which isn't food/seasoning/salt: methylcellulose. However, it is derived from plant cellulose, and is basically a semi-synthetic equivalent of pectin, a natural product (or other dieta

That still seems like two primary groups: meat simulacra and simply veggie-based primary protein. The "try to approximate meat" is usually the main driver of cost/ingredient complexity.

Here in USA, single-gang switches have "on" and "off" embossed on the switch, so the state is shown based on the position (oriented up is on). Multi-gang switches have no embossing.

Well yeah that's kind of what I mean. On some libraries you can generate and encode just the timestamp part.
