skillissuer,

if you get people to argue, you can pump users engagement statistics. same with conspiracy theories, and neither makes place that does this worth visiting (like facebook does)

skillissuer,

ah yes, the military aid worth quick maths american defense budget for quarter of millenium. i think you're off by several orders of magnitude on this one, somewhere about five

skillissuer,

didn't want to start new thread for this so: second page of content never loads for me, and lots of posts/comments that i would expect in my profile and some communities, especially non-local simply don't show up. anyone else has the same issue?

skillissuer,

yall are going around on the internet without ad blocker in current year?

skillissuer,

i indeed have no source for that, so i deleted this

skillissuer,

of which some 80k are new, and of which some 20k are counted as active. not great, not terrible, we'll see what becomes out of this

skillissuer,

... what i am looking at, why there are turrets on a building

is that their best attempt at recreating ww1 era fort? is that a museum, training center or something?

skillissuer,

so you all folks are leaving your reddit content be? i'm deleting everything by hand

skillissuer,

so apparently 100 KIA and additional 100 WIA were caused by some attempt at motivational talk by chechen general in HIMARS range https://nitter.snopyta.org/wartranslated/status/1668973712098443265#m

anyone fancy a reformer take wrt archery? https://solar.lowtechmagazine.com/2022/11/what-if-we-replace-guns-and-bullets-with-bows-and-arrows/

i don't even know where to start with this thing, folks. i'm at actual loss of words and can't even

skillissuer,

let me help you: https://github.com/j0be/PowerDeleteSuite

skillissuer,

ncd be like:

The gun is good. The penis is evil. The penis shoots seeds, and makes new life, and poisons the earth with a plague of men, as once it was. But the gun shoots death, and purifies the earth of the filth of brutals. Go forth and kill!

skillissuer,

imagine a container with no gases inside. let's introduce some liquid here - it will evaporate until some kind of equilibrium is reached. pressure of vapor achieved is called vapor pressure and is strongly dependent on temperature. if pressure of gas above liquid is equal to vapor pressure, liquid is boiling.

you can make any liquid boil by decreasing pressure or increasing temperature, and conversely you can any gas condense by decreasing temperature or increasing pressure. if you look at a phase diagram there are regions where liquid or gas is stable. if you have liquid in "gas stable" area, it will evaporate, and if it's the other way around, it will condense.

let's cool down top surface of that container. vapor will condense on it, lowering pressure, making liquid on bottom boil, which decreases its temperature until it can't boil at a given pressure. more vapor condenses and eventually bottom part reaches temperature of our cold source. this device is called thermosiphon. this way we transferred heat from bottom to top of container. if you make it so that liquid covers entire surface of container, for example by use of capillary forces, this device can transfer heat from any orientation to any other. this is called a heat pipe.

if you want to transfer heat from colder to hotter area, you need to make liquid boil at lower pressure and condense at higher pressure. you need to put some energy into that and this device is called a heat pump. notice that the lower the temperature difference is, the lower pressure ratio becomes and the more efficient entire thing is. the trick is, at low temperature differences amount of energy needed to run the pump is small compared to amount of heat moved around. there's hard physical limit on this - it's inverse of maximum (carnot) heat engine efficiency at these conditions, it can easily reach 3x-4x in practical implementation.

you can even reverse this and extract useful energy from temperature difference. this is called heat engine and about all (non-hydro, non-wind and non-photovoltaic) electricity generation runs on it. you can even treat these renewable energy sources as a heat engines, in some cosmic sense - taking heat source and heat sink as temperature of sun and temperature of photovoltaic panel, for example (with additional limitations)

skillissuer,

like a true nazi state, russia wants to get rid of undesirables: criminals and the extremely gullibile (through wagner), minorities, the clueless an debtors (mobiks). you'll find out that mobilization orders weren't taken very seriously in moscow, but were in bashkiria and tuva (at least at the beginning). far east has few jobs available, in one far eastern region like half of population is in inescapable debt. army gives stable if shitty job. you can dodge draft if you know who to pay but if you don't have money, this doesn't work

skillissuer,

wagner had 50k in dec 2022 and it was probably peak, before february 2022 ru army had 300k active duty, so i'd say it's somewhere between 1/10 and 1/100. closer to 1/100

skillissuer,

oh yeah this counts manpower only, and maybe small arms and some light equipment are in similar proportions. wagner has, for its size, little heavy equipment, virtually no engineering equipment, and shoiguu where is my ammunition

skillissuer,

that was their peak, remember just bakhmut ground down low tens of thousands of them (20k? 25k?)

skillissuer,

i think that's the job of RDK, but don't quote me on this

skillissuer,

obligatory https://acoup.blog/2020/03/20/collections-why-dont-we-use-chemical-weapons-anymore/

skillissuer,

to add some noncredibility: did you know that soviets had this big brained plan to dispose of chemical weapons by nuking them? the idea is that chemical weapons can't be harmful anymore if they are turned into plasma. according to some calculations it was even cost-competitive with chemical neutralization

skillissuer,

one thing to note that scihub (and maybe other options) doesn’t preserve supplementary info. usually it’s freely available, but elsevier for example likes to constrain access to it
