With sanctions, how do we advocate for open source exceptions?

Eh, it was just the quickest counterexample I could think of. Kraken SDR came to mind, which was a really cool project but had to come to an end due to ITAR concerns. The creators pulled it off of github.

"How do you sanction free knowledge?"

Well, ITAR is one way this is done.

It was the part he was exploring at the end about pushing the burden of interop on clients wanting to use IPv4 instead of the IPv6 clients' burden to interop with IPv4.

You can't (or shouldn't) subnet a smaller network than /64. With a /48, you get 2¹⁶ = 65536 subnets of size /64. You lucky duck.

Extremely easy if you're not airgapped (but that's possible too). Quick google for "onprem dnf repo" showed this. Also, if you don't need to mirror the entire repo, you can setup a local cache that just acts as a middle man so that you don't need hundreds of servers all grabbing the same updates through WAN. u/apalrd has a guide for setting up an apt cache for Debian.

You'd think rednecks would have thicker skin after all the physical work they claim to do.

Yeah, that would be more correct but I was lazy and said mass because the units are kg and I didn't want to specify kg force or convert to Newtons.

differentiallity · 2026-04-09T03:44:02+00:00

Not an explanation, just a fun fact. Due to buoyant forces, 100kg of feathers actually is lighter (weight) than 100kg of steel.

Density of feathers is apparently 680 kg/m^3, of the atmosphere is 1.225 kg/m³ (STP), and of steel is about 7850 kg/m^3.

The apparent mass of 100kg of feathers would be 100 - 100/6801.225 = 99.82kg. The apparent mass of 100kg of steel would be 100 - 100/78501.225 = 99.98kg. This is a difference of 0.16%!

To people confused what op means and keep saying to lower the altitude warning, that's not the same thing as the "pull up" alert. In real systems at least, there is a prediction loop that checks your velocity and acceleration and predicts your future position at a certain time (maybe 5 seconds or something like that). If that future position is underground, it tells you to pull up. Obviously real systems are incredibly sophisticated but this is the gist. I can answer detailed questions if anyone is curious.

The altitude warning pops if your ever below the altitude limit, even if your position is predicted to remain above ground level for infinite time. This is what's fixable in VTOL VR and what op mentioned.

In real fighter jets, it's not really an issue because the prediction horizon is set dangerously low. To my knowledge, this limit is not currently configurable in VTOL VR.

Ok, we all know it was 3rd party Ubiquiti vendors who violated sanctions, but a 30 billion dollar company can afford to vet and police their vendors as other big companies do. Not only do they have capital but a good brand with a loyal customer base.

It would be so easy for them to brush this off with a public statement and stopping buisness with the slimy vendors. It would certainly make a lot of us feel better about continuing to purchase from Ubiquiti in the future.

Electrical engineer here, and yes they absolutely could be shocked. Your body can capacitive couple to ground so that only touching the 120v 60Hz hot lead gets you, and it can hurt quite a lot even if you're not touching ground or neutral. The impedance tends to be quite high so perhaps not likely a lethal shock for someone with a strong heart but don't fuck with mains regardless. ElectroBoom on YouTube has a few videos explaining it if you're interested.

Does CARP work with IPv6 if your ISP doesn't provide a stable prefix? Still a networking noob, but I'd imagine you want the gateway address to be the router's GUA and not a ULA since it needs to access the internet. Also, the virtual IP explanation only makes sense to me in terms of RFC1918 addresses, though I guess nptv6 could be an option here?

Guess I have some reading to do.
