Just like with snipers today, although i suspect that giant laser is not optimal weapon in high stakes hide and seek game

You can’t hide those from ground-based anti-satellite laser

It’ll be like with GBAD in Ukraine but in space, and satellites can shoot at other satellites too

fair assessment, tho i wouldn’t use chatgpt even for that

despite phase shifts being the main cause of the described effects.

what are the other ones?

(when i’m thinking about splitter with pi/2 phase shift, i’m thinking about coupled line coupler or its waveguide analogue, but i come from microwave land on this one. maybe this works in fibers?)

skillissuer, 7 months ago

pi/2, sorry

In microwave land we have something called rat race coupler which can be used as an in-phase 1:1 splitter. This thing can be manufactured in waveguides so maybe (narrowband) fiber optic implementation is possible

with that kind of accuracy, it won’t hit anything, which leaves one option - increase in firepower. Fortunately physics allows for construction of nuclear device that fits in 203mm shell, let alone 238mm which was this thing

(i’m sure whoever came up with AIR-2 Genie also would like idea of nuclear anti-air artillery)

(technically it’s even nuclear SPAAG even if it needs rails)

most lately construction of similar kind of gun was attempted under Saddam “▇▅▆▇▆▅▅█” Hussein as Project Babylon. it didn’t work because required high pressure pipes were intercepted and head engineer was assassinated

this was done by the same guy who, at first try, wanted to send satellites to orbit using a giant gun, as DoD Project HARP. it also didn’t work, but at least it was useful for atmospheric physics research

Yeah nah, we had (in Poland) at least a few high profile cases where pregnant women died because they were denied abortion, directly due to recent-ish abortion bans

skillissuer, 7 months ago

well, we just had elections and new govt is expected to at least reverse the worst bits. this won’t happen until early next year tho. (still) currently governing PiS took a hit in polls from some 42% to some 30% due to these bans and subsequent protests in 2020-2021, from which they never recovered and that cost them elections. you could say it kinda works just not as fast as everyone would like it

bonus side effect: now, solely due to that fundamentalist fuckery, there’s more support of not only going back to what was before, but going in line with other euro countries ie unrestricted access to abortion

so russians lost another su-25 today yet they sell newly manufactured manpads to india, for rupees, that they have problems to spend anywhere else than in india, and india is not selling them weapons because that deal goes the other way around. truly a 7d backgammon with time travel move

Gram of tungsten has a mass of something like 15 grams

I’m referring to Rogozhin’s idea of putting FAB-500s as a payload, boompaste doesn’t tolerate such conditions

i’m not sure that drag even matters that hard, you need big sectoral density and a way to prevent tumbling

en.wikipedia.org/wiki/Impact_depth

Meteorite: As may be concluded from the air pressure, the atmosphere’s material is equivalent to about 10 m of water. Since ice has about the same density as water, an ice cube from space travelling at 15 km/s or so must have a length of 10 m to reach the surface of the earth at high speed. A smaller ice cube will be slowed to terminal velocity. A larger ice cube may also be slowed, however, as long as it comes in at a very low angle and thus has to pierce through a lot of atmosphere. An iron meteorite with a length of 1.3 m would punch through the atmosphere; a smaller one would be slowed by the air and fall at terminal velocity to the ground.

talking about tungsten we’re looking at minimum 50cm long darts, however this ignores atmospheric erosion

skillissuer, 7 months ago

tungsten darts from space sounds relatively sane already. what the boss of russian space agency came up with is putting pallet of FAB series bombs as a payload of an orbital delivery rocket, but instead of putting them at orbit, using it as a giant ballistic missile. take a minute to appreciate how stupid idea is this: at these speeds explosive provides something like 20% of total energy if not less, and you can’t target them really well without good guidance package. if you slow it all down to make aerodynamic guidance easier, you give up the primary advantage which is speed, making it a target for GBAD. all of these bombs would need to survive reentry, and russians don’t have IMX

it’s not rods from god, conventional FOBS, or anything like that. it’s much more stupid: it’s rogozhin trying to make himself relevant again

Higgs boson has mass and quite large one at that and this puts limitations on how hard is it to generate it and on how field behaves

When you don’t provide enough energy to get whole Higgs boson, interactions happen via virtual particles. It’s easier to grasp this idea with weak interactions and W and Z bosons

does tetra being backdoored matters if the only people that can use it are cops and such?

skillissuer, 7 months ago

Great, now look at the actual vulnerabilities

Zeroth of all, the people who have backdoor - EU intel agencies - don’t have any motive to attack TEA1 radios within their range. This might provide them with tools to snoop on non-EU firetruck radios, but that’s all. That’s some very limited NOBUS capability

First of all, it’s an attack on something that is transmitted most usually on 430ish MHz - you need to be within few km of target just to listen. This is enough to break TEA1 if you know about the backdoor, but if you want to do anything more - like exploit CVE-2022-24401 - you need to be close enough to receive victim’s signal, but also you need to spoof part of base station signal - remember, you don’t wanna get caught, so you have to use low power and point directional antenna at cops - and you need to be even closer, maybe even following them within line of sight for it to work reliably

Proof of concept code wasn’t published, you still need considerable resources to get to exploitation in principle in the first place and then you have to be physically close to decrypt some communications. This still doesn’t allow for sending forged messages because there’s also authentication mechanism that you’d also need to take care of. This is some state-level resources, not two dudes in a shed scale of resources

skillissuer, 7 months ago

I get what you’re saying, i’m saying that average joe hasn’t really been exposed much because distribution of this vulnerable technology is limited and actual exploitation has some serious constraints

GMLRS guidance package has access to military codes, so it’s probably harder to jam

and beyond that, jamming doesn’t matter that much unless you jam considerable length of missile path. if GPS signal is not available, it just switches to inertial. the later this happens and the better INS package is, the lower error you get
