The point is not gain of land for Russia but removing land from another state, as a punitive measure for trying to get away from russian influence. This is also not the first time it is happening. Because of how nationalist Putin’s supporters base has become over time, he chose to use small invasions like 2008 invasion of Georgia as a tool to increase his domestic popularity. This parallels 1999 false flag bombings and response in form of second Chechen war and 2014 invasion of Donbas. In all these cases, as well as for two first weeks of 2022 war, approval rating of Putin’s government soared which was exactly the point the entire time. Because of how much of that comes from nationalists, he can’t back off because he’d come across as weak and lose support, he can’t advance much faster because he’s physically unable to, and his best bet is this kind of slow grind like we see now. Any western military aid will make it harder, so of course russian influence operations are directed against it, and you know that too
Also you will not be scaling up domestic weapon production to any meaningful degree
Speak for yourself. Orbital ATK buys european explosives, we have scaled up weapons manufacture in France, Germany, Poland, Romania, Bulgaria, Turkey, Czechia and few others, there are new Rheinmetall plants in Ukraine too.
Ukrainians don’t lack resolve. In 2022, something like 85% (iirc) said that fight should go on if nuclear weapons were used by Russia. Even now 80%-ish don’t think that any territorial concessions should take place in any peace agreement. They have some of their own defense industry, lots of things (other than mostly air defense, and parts of aircraft manufacture) we can do in Europe, even if it requires some scale up, then there’s South Korean deliveries and few other things that still can happen.
Like when the swastikas came out and the genocide in Palestine kicked off, you should have realized we’re the baddies, and baddies lie.
who the fuck “we” is supposed to mean there? in middle east i wish everyone involved regime change, situation is fucked with any of current people in power staying in power. Put Netanyahu, Assad, Erdogan, Khamenei and their cabinets and top people from Hezbollah in Hague then we can talk. but it’s severely off topic so maybe don’t

reproductive habits of some insects are of critical importance in pest control in agriculture
natural product chemists (it’s a subfield of organic chemistry) find and identify new weird shit in obscure organisms (esp marine organisms) all the time. because amounts are tiny, then their work is on synthesis of the same thing. some of these turn out to be useful

“hey why bother going against a nationalist land grab? i am the real antiimperialist” gee i wonder
most of the rest can be made in europe, even if it would require some scaling up of production
- Comment on Habits of Insects 3 days ago:
also, entire military is just under 1tn - all of it, including completely nonmovable things like nuclear silos and submarines. ripping enough copper from the walls to get 2tn would involve massive cuts to social security and healthcare, and maybe education. but nooo heavens forbid that progressive tax on income be introduced

i, for one, would like to see more air defense assets going to Ukraine

“preventing next corn plague” with resources used being a box of soil and bunch of underpaid grads seems pretty efficient to me, but i guess that since the common clay of the new west already voted they can be safely disposed of
at USDA, they’re turning beetles kinky! 😡

If you don’t live in complete wilderness and especially if you are in repeater range then yes, there’s a lot of use of 2m/70cm. There are even commercial duobanders for this, but you can also make your own
Lots of things change between HF and VHF. Matching methods, baluns, and materials are completely different. You can get away with 70cm band antenna made of 8mm aluminum tube, and it’ll get you some reasonable bandwidth just because of how wide it is, but if you want to scale it up to 20m it’s suddenly over 20cm wide. This is not practical anymore, but you also don’t need bandwidth like this. HF antennas (other than masts) are mostly made of wires and rely on things other than thickness to make them wideband enough. If you want to use monopole, on VHF/UHF you can use metallic roof as a groundplane. On HF you’ll need to use actual ground with network of wires, which is lossy. For dipoles, distance to ground will be many wl long on UHF, and it’ll work mostly like in free space, but on HF this changes impedance, losses and radiation pattern. On HF, polarization is scrambled after reflection from ionosphere, on UHF it just goes through

What bands are we talking about (HF or 2m/70cm?)

Solar panels, specifically inverter is likely to generate a lot of noise

fern? germ factories
there were a few stupidly close calls in soviet biological weapons program
- Comment on 10 Ways to Destroy the World 1 week ago:
2 means “just” removing earth’s magnetic field, van allen belts don’t shield from anything, these are trapped solar wind
5 could have side effect of disturbing ozone layer, on top of, yknow, just suffocating every animal
7 is not even wrong
10 sounds like CIA’s final plan for assassinating Castro: just let him die of old age

Go to the content you’ve banned them for, then in options instead of Ban there’s Unban. You can find it in modlog
If it’s not there, you can always ask instance admins to do that

this is less of a problem when you don’t use it for energy, but instead as a feedstock like in synthesis of ammonia or steelmaking. you can make ammonia in many places, but it’s not the case for steel
- Comment on Know thy enemy 1 week ago:
you’re probably talking about direct reduced iron and it’s really a problem that can be dealt with easily, just chuck a piece of coke when it’s molten for the second time in electric arc furnace (and maybe electrodes introduce enough carbon)
maybe there’s a way to make electrowinning iron economical, and it’d be pretty green too, but i don’t know if it is workable

no we can’t make hydrogen everywhere, there will be regions with large excess of renewable energy compared to population. these places could export hydrogen. you also don’t need a lot of transport if crude is extracted near place where it’s used, like for example heavy crude from alberta
- Comment on Know thy enemy 1 week ago:
coal can be substituted to some degree with processes like direct reduction. hydrogen works but syngas from biomass or trash also works
- Comment on Know thy enemy 1 week ago:
not now, but if hydrogen were to be used as an energy source/storage, then it’d be used plenty. same with batteries

- Comment on Know thy enemy 1 week ago:
ikr, but that tweet implies that all of oil/gas/coal ships would be unnecessary
- Comment on Know thy enemy 1 week ago:
this is arguably fine, because this way ships make clouds of sulfate aerosols, which have slight cooling effect and no one is bothered by it when it’s released over sea
- Comment on Know thy enemy 1 week ago:
Some of these ships would carry green hydrogen and new lithium batteries and old lithium batteries (to be recycled) and whatnot. Also at least some oil would be still needed for fine chemicals like meds or (idk what’s proper english term for that) large scale organic synthesis like plastics, or even straight distillates like hexane (for edible oil extraction) or lubricants. Some of usual non-energy uses of oil can be easily substituted with enough energy like with nitrogen fertilizers but some can’t

there are a few, but these are small and new, and most of the time null results are published along positive results, not on their own
you can mirror entire scihub repository, it’s listed as hundreds of torrents somewhere, each is zip of 100000 pdfs. i think it’s under 200TB
