Yet another science piece that perpetuates the misconception that “the mass extinction killed the dinosaurs”. The clade of dinosaurs is not extinct and it bothers me that science writers don't seem to learn this fact and keep getting it wrong.

'The extinction of non-Avian Dinosaurs' just doesn't roll off the tongue.

The US military has known this for a long time, it just chooses to bury its head in the sand and ignore it.

See e.g. MC02 where they lost to opfor with what was literally like a cheaply thrown together zerg rush, and then just reset the scenario for a do-over.

sornaensis · 2 years ago
MC02 had a lot of problems but calling it a zerg rush exposes your ignorance-- it was a very sophisticated and well-coordinated surprise attack. The people running the wargame rejected the outcome as a likely tactic to be used by the hypothetical adversary and guess what, they have been proven right, see: the war in iraq. The iraqi army completely failed to hold initiative against the coalition or organize coherent resistance nevermind launch a coordinated surprise attack ahead of the invasion.

The other aspect that is missed in criticisms of this particular wargame is the fact that there were specific doctrine elements that were to be tested-- now the claimed outcome of those can be debated, for instance the fact that opfor had many restrictions on how they were allowed to employ their anti air defenses-- but a wargame is NOT meant to be a giant game of paintball where when one side gets hit they just pack up and go home, that would be incredibly wasteful. In many cases you have formations planning and training for months to participate in the exercise. The purpose is testing out many different aspects of doctrine, and often times that involves 'ignoring' results of one part of the wargame.

This is a pretty interesting article but the conclusion is literally insane:

> For all these reasons, rather than keeping weapons out of the sustainability discussion – they should be our focus. If we cannot imagine low-tech warfare, we cannot imagine a low-tech, sustainable, and fair society. Switching to low-tech weapons sounds unrealistic because it would require global cooperation, but the same holds for lowering the emissions from fossil fuels. Switching to low-tech weapons sounds unrealistic because it involves “uninventing” things, but this also applies to many other problematic everyday products.

> Indeed, military technology is one of the few domains in which we have collectively decided not to use certain technologies. Humanity has banned many types of weapons in warfare, such as chemical and biological weapons, blinding laser weapons, and poisoned bullets. Meanwhile, no country has succeeded in outlawing SUVs, although their danger to other road users and the environment is well-known. As weird as it sounds, military technology leads by example

If you investigate all banned weapons though, you'll find it's more to do with practicality+cost+optics than some high minded agreement. Wars fought today are still brutal, and people use anything that will get them ahead.

So e.g. chemical and biological weapons are pretty poor performers when you put them up against conventional weapons.

For one thing, both can backfire greatly if for example they are improperly handled behind the frontlines. Weapons need to be stable and easy to handle and able to deal with fuckups without killing your own people.

They also are expensive as hell, it costs a lot more (and is probably harder) to find competent people willing to make these types of weapons, and per dollar, they don't kill as many people as conventional bombs do. (See: World War 1) So, they are 'banned', but mostly because they aren't very effective.

When you look at so-called chemical weapons that are in use, they are usually used for temporary area denial, are stable, not that lethal, if at all, and easy to produce: white phosphorus, CN and CS gas, etc. The US of course calls white phosphorus for 'illumination' but the people firing it know what they're using it for. So when they do beat out the alternatives, they get used anyway.

Laser weapons are being developed but they are basically just not there yet. Batteries are heavy and the usefulness seems pretty limited to shooting down incoming drones/missiles possibly. Just using anti-missile missiles or just a stream of bullets is still cheaper and more reliable. Again, if you can see and hit someone in the eyes with a laser, why not just shoot them with a normal bullet? The economics don't make sense.

Poisoned bullets I haven't really heard of, I'm not sure what kind of poison would survive being coated onto a bullet and fired out of a gun, or how making a really expensive nerve agent bullet and then shooting someone with it is better or more sensible than just shooting them with a regular bullet so I can't really comment.

Expanding ammo was 'banned' but again, it was essentially replaced with spitzer style rifle bullets that are more accurate and effective anyway, and can have a similar result on impact.

tldr it's not a good comparison to call these things actually banned in a meaningful sense.

I love this recording and the longer recordings of Hitler speeches because all that is left in popular memory is the wild screams and crescendos that he would use at the end of his speeches. When you read accounts at the time people would talk about Hitler always starting quietly making you listen, and then slowly building up the pitch in the further of his meetings. They described as almost hypnotic. There’s a great fictional series that was done on Amazon – the man in the high castle – where they really leaned into this with their portrayal of Hitler.

There’s a lot of value in studying how leaders convince and control the masses.

If i recall correctly, there is also a part in the transcript where he admits he just didn’t know Russias true strength, and he never would have invaded had he known. Remarkably different language than he used at the time.

Hitler had (poor) intelligence that the Soviets had thousands of tanks (they actually had more than the germans thought); he refused to believe that such a 'backwards' country could have such a strong modern military however.

You didn’t look very hard. Main is very special in Haskell.
sornaensis · 2 years ago
The entire point of Monads, is restricting the ability to do these operations into functions that are tagged with having this ability, precisely so you _cannot_ invoke IO in a random pure function. It's the entire point of the language in fact.

If you want to just write IO, you can just define a function with an IO () value and use it in any other function that resolves to IO (), or call other functions that live in IO *, or any pure functions, etc etc.

So does this require new physics to solve? What should the layman take away from this?

>distant galaxies have been speeding up in their recession, and the expansion rate, though still dropping, is not headed toward zero.

If the expansion rate is dropping, surely it is headed towards zero? Or are they using expansion rate to mean acceleration and the zero refers to the recession. Or am I misunderstanding something?

sornaensis · 2 years ago
I took it to mean the rate of expansion is approaching a horizontal asymptote e.g. -x/ln(x), x > 1

I think much of the song arrangement is likely from Lars.

There is a video somewhere of Hammett describing how he shared a riff for one of their songs and Lars said "play that but 3 times them end on that" or something to that effect.

Live performances may not be super tight but it's OK because Hetfield is a better drummer (at least he keeps the rhythm)

sornaensis · 2 years ago
For sure, the band is Lars and James. People like to hate on Lars and Hammett out of jealousy I guess, they’re both really successful in a genre that celebrates technical prowess, while not being technical players.

Is it because of the Napster thing? Or there's more to it.
sornaensis · 2 years ago
If you have any musician friends who are into metal, ask them what they think of Lars as a drummer. :)

I don't see a meaningful distinction between "preventing disease" and "preventing spread of disease" in this context given we're talking about pathogens.
sornaensis · 2 years ago
The doctor isnt the one in danger dying or getting sick, that seems like a big distinction and probably the reason people were skeptical of it.

I also seem to recall a factory or trade uprising/strike in/around Europe between 1400-1700 where they basically made up whiteness to divide the laborers and get them to argue amongst themselves (successfully), but this may be apocryphal as I cannot seem to find a source.

sornaensis · 2 years ago
Really, people had to be told that people with white(r) skin, are similar..?

How stupid do these people think 'everyone else' is. This is the most absurd thing I've read all day.

Humans, who divide themselves along such lines as _what tv shows they like_, had to have the concept of _skin colour_ invented for them. Really think about how ridiculous this assertion is.
