oh i must have missed a few orders of magnitude there. 6Mt of helium is a ridiculous amount though ... what is all that used for? according to WA that is about the water volume of the three gorges dam at STP

Edit: just read the report, wow, more than a quarter of all the helium is used just for "breathing mixes" which i assume means its for scuba diving.

from the wiki article on Helium:

an estimated 3000 metric tons of helium are generated per year throughout the lithosphere.

I think the main issue here is not that we are loosing helium on a planetary scale but that the easy to reach helium from gas wells is wasted. We will never run out of helium at our current rate of consumption before the sun goes nova, if we consider all sources on earth, but it will get a lot more expensive and the supply will get less steady.

this is extra tricky because they did not specify the exact kernel. mainline could be any of the kernels tagged as stable that you can build from linus' git tree. i know that in the past you could run a mainline linux on intel 368 chips but today you probably can not because official support was dropped a while ago.

I think what he was trying to point out is that you should not expect a direct visible effect of the dwindling funds on the events on the battlefield. It will be much more indirect and delayed by month, maybe years.

Will it also allow the placement of entities to be parametrically changed? like the changing the position or enabling/disabling the placement of specific entities?

I mean sure but on the other hand the Ukrainians have modern radar so this is a bit surprising still.

I think it went a bit further than just selecting the right paint.

I remember there was a program to enhance the stealth for relatively low flying surveillance aircraft (still mostly propeller aircraft at that time) and one of the most effective measures was painting the underside of the plane White and then illuminating it on purpose with a light that was matched to the sky. The light was usually bluish to match the sky. https://en.wikipedia.org/wiki/Yehudi_lights

The reason why this was not simply done at night was of course that the surveillance equipment needed some light to work :)

i searched for the exact phrase used "robot which uses plasma torches" and found a few news articles for a start-up that uses such a concept in commercial tunnel drilling.

so i guess we do have tunneling robots that use plasma torches.

i did not see any text that mentioned the guided variant but i saw a video that showed supposedly a UA gunner in a PzH2000 with a programming adapter on a shell like they are used with Vulcano ammo. (looks like a round copper ziggurat)

Edit: just read the description of those shells by the manufacturer and i i think i misunderstood programmable shell to mean guided shell. the programming could also be for setting the fuse.

They have guided Vulcano ammo in that caliber too.
