people see strait closed and think of oil because of course there's a lot of oil going through it, but oil can be routed through pipelines outside gulf so impact on oil is less than that 20% commonly cited

the bigger impact is on gas, because it can't be transported that easily and it's closer to 40% of supply. because gas is so hard to transport you can try to avoid doing that, so it's turned into fertilizer and diesel and aluminum, whose transport is easier, and isn't as constrained as LNG transport. byproduct of gas mining is helium and it can't be mined on its own, and while valuable enough to be flown out of qatar supply stops when gas stops. gulf royals have seen that world tries to get rid of oil, so this energy intensive manufacture was intended as a sort of hedge or insurance, but this too stops without transport

so, yeah. things that can be expected to directly get more expensive are energy in general and gas in particular, plastics of all kinds, aluminum, nitrogen fertilizer and to some degree phosphorus fertilizer (uses sulfur as input). and everything that depends on them, which is broadly everything. the only winning move is not to play ie use renewables for energy. these chinese officials who backed renewables buildout are probably the most vindicated people in hemisphere

that said, you can make fertilizer from other fuels, and in other places too, so it's likely that it will "just" get more expensive, and lower nitrogen use might work about as well because many farmers overapply it. if you are a westerner i guess you might not see it hitting you tok hard, but in places like sudan that will be a problem

what is your threat model? the fact that one person can't plausibly know many advanced fields at once in sufficient detail limits risk significantly when you don't ignore that experts are rare

it was heading from baltic. well, maybe they used to in vladivostok, but probably no longer

On October 13, 2022, Vostochnaya Verf filed an application with the Primorsky Krai Arbitration Court with a request to declare it bankrupt. According to the results of 2021, the company received a large loss and cannot pay for its obligations.[8]

also lots of heavy industry is where people live, that is in western part of russia. otherwise you have to haul steel all the way there, it would make complete sense to put the only nuclear reactor factory in area where you have all the specialists

could be, there was more of these weird things that i had to do that i don't remember already because motherboard of that one cracked like three years ago. i also remember that stock driver for tplink dongle was limited and the actual useful one had to be gotten from github

must be greenpeace, move along nothing to see here

(also it's old news atp)

to get wifi working properly in the first place i had to find a missing binary that wasn't packaged in any normal way and was only hosted on some dudes github so my expectations were low already. it got a lot better over the years tbh

lmde on a seven year old laptop five years ago, i was already accustomed to wifi on linux being dogshit. energy management was even worse and for some time hibernation was not a thing

Can’t you just disable sleep on close?

i could, but closing the lid turned off radios (wifi + bt) at some low level in a way that i haven't figured out

ah yes that must be that famed democratization that cryptobros yammered about

i think that perun took sponsorship from 80000 hours years ago, once, and eas or anyone in their milleu never reappeared

pigments are the least problem, and many are not dependent on oil, like titania. some might, like soot, but because we're talking about japan, it's likely they get it from chinese manufacturer, and chinese chemical industry relies on coal heavily. but it's such a small part of it all, binder, solvent and the entire packaging are likely petroleum-derived or dependent so there's close to zero savings here. not to mention fuel and fertilizer use in farming that led to that product

it's such unbelievably petty corner cutting, the only value of it is in marketing

you know what would help them? switch to solar process heat, best time for it was decade ago, second best time is now (they're using heavy fuel oil for heating something)

weirdly sbf-shaped failure mode, wonder how it helped that court case

 

I'm picking up an idea left by Dick KK4OBI, that you can lower impedance of dipole by arbitrary ratio if said dipole is zigzagged or otherwise uniformly contorted in some meandering shape. Side effect is that dipole becomes shorter and needs more wire. While there's data about impedance for fundamental, there's nothing about harmonics which is something that OCFD might be expected to handle well, so guessing that the really important part is aspect ratio of meander, i've made a couple of VHF-scale models with different meander aspect ratios (and many more much smaller sections), and some of data i've been able to collect roughly matches. The thing I'm trying to figure is what aspect ratio should be to cover multiple bands while using OCFD, say 40-20-15m bands, and whether impedances at different frequencies fall at the same rate. Eventually, when i figure this out, i'll try to make a full size 40m fundamental antenna, as I think that i've figured it out in mechanical terms

However during testing it turned out that I have severe common mode current problems, as two 10mm dia split ferrite beads were evidently not enough, so what little i've been able to collect is mostly useless. When I packed up everything I've found 4 Laird 28B beads that should together give 1100 ohms of impedance or so at 100MHz which also happens to be close to lowest frequency in my setup. Is this enough? Feedline is currently about as long as shorter arm of straight dipole at 22,5:77,5 split ratio, should I change it?
