lol @ the implication that chatbots will definitely invent magitech that will solve climate change, just burn another billion dollars in energy and silicon, please guys i don't want to go to prison for fraud and share cell with sbf and diddy

who is this guy anyway, is he in openai/similar inner circle or is that just some random rationalist fanboy?

I hear that this happens sometimes, but nowhere near normal times, more like during evacuations from warzone and so on

sorry for being unclear, i forgor a word. what i meant that certain antenna designs would have specific fractional bandwidth, so that just scaling that design to higher frequency makes usable bandwidth wider in kHz terms. in order to get higher fractional bandwidth more complex or bulkier designs would be required, like thicker conductors, added parasitics, something LPDA-shaped, or maybe elaborate matching circuit, all of which cost money. i guess that while resonant amplifiers are a thing, probably bigger limitation would be bandwidth of mixer

i'd also note that antennas, amplifiers and so on have bandwidth that is some % of carrier frequency, depending on design, so just going up in frequency makes bandwidth bigger. getting higher % of bandwidth requires more sophisticated, more expensive, heavier designs. LoRa is much slower, caused by narrowed bandwidth but also because it's more noise-resistant

but there's separate category for "broadcast", so it's more of point-to-point thing?

what's fixed service in this context?

that key to heaven was probably something between mistranslation and bs, but there's so many more awful shit!

electric swamp - iraq used swamps as a natural barrier, laying mines, placing mortars and HMGs around, and also putting high voltage wires in water. when iranian raid was detected, they'd just fire a bit until iranians fell to water, then turned power on

BWR fights - phoenix missiles on iranian tomcats. iraqis had no idea what's going on to the point that they suspected sabotage (mirages just fell apart in air for no reason)

war profiteering - lots of countries sold covertly weapons to iraq or to both sides, but swiss were probably worst: they sold gas masks to iran and chemical weapons precursors to iraq

ww1 era warfare complete with said chemical weapons, and also genocide of Kurds for some reason

and all for nothing (result: status quo ante bellum)

Both got much more interesting. Also, don't underestimate modern encryption

cyanide doesn't accumulate, it can be broken down in some hours (very small amounts of course). otoh many heavy metals do behave this way, maybe you worked with both at the same time

[–] [email protected] 12 points 1 week ago

all metals that bind to sulfur well are to some degree poisonous. these are lead, mercury, thallium, some platinides (in salt form), arsenic, and also copper, but less than others. some metals have other mechanisms of toxicity, like nickel, hexavalent chromium, cadmium, beryllium or barium. some of these accumulate in brain or bones, and some don't. some are more toxic when inhaled like zinc or chromium

it's absurdly easily detected and somewhat easily treated today, not in op's setting

slight update (discuss.tchncs.de)
 

russians seem to have launched another offensive on Vuhledar, there won't be any other result so you can pretend this meme is from the future

edit: orange bar was entirely too long and also i don't know how gradients work

 
 

don't ask whose plan tho

 
 
 
 

when T-34?

there were already two T-55s lost per Oryx first and second

 

might be too credible

of course he was afraid of russian nuukes. this only prompted Ukrainian engineers to bypass use of starlink entirely and current sea drones, like the one used in second Kerch bridge strike, or these used against SIG tanker and Olenegorsky Gornyak landing ship use domestic technology only
