It makes me think that maybe he doesn’t want to stop the war, he’s just tapping me along, and has to be dealt with differently, through “Banking” or “Secondary Sanctions?”

People were trying that last year already, together with the arms deliveries. Until you came along and fucked with everything. You claimed to have such a great plan that you could end the war in 24h. Now, after 2307h in office you realise what everyone knew years ago? Truly a genius.

Well the packages from the default repo are vetted by your distro maintainers. So if you just install a package from your distro's repo you're still relying on the security of your distro.

If you go outside of that, either to get a FOSS package that wasn't packaged for your distro, or to get a non-FOSS package, you have to do your own due diligence, just as when you're downloading a third party package for Windows or macOS. Either by reputation or by finding someone trustworthy who has actually checked the code.

“The extraordinary thing is that lie detector tests are being threatened not to uncover potential anti-President Trump civil servants but to catch political appointees suspected of leaking classified or sensitive information,” a source in defense told the paper.

Sorry what? How is that extraordinary? The opposite, which seems like the sources preferred suggestion, seems way worse?! Loyalty tests are not justified by anything, leaking classified information could at least be a crime providing some justification.

In females it's the same. Skene's glands sit on the urethra.

Wow interesting! Thanks for checking the label!

Yes, and that's before muxing!

I need only 75 GHz of spectrum to send 400 Gbit/s through our country. We've currently got a link running between Zürich and Lugano (two amplifier sites in between, before and after the alps), and I've got 4400 GHz of usable spectrum with our currently deployed system, so if we needed it and spent like two million dollars we could deploy 23.2 Tbit/s within months, using just our normal commercial stuff, on a single fiber pair.

Using G.657.A2 fiber you could get away with 7.5 mm bend radius, or 15 mm diameter, for the innermost layer of the spool. That's around 5/8 inch for freedom units.

But then again if you went that tight you'd need like 56'000 windings for 10 km. That sounds like a fuckton, and like we can't ignore the outer diameter being larger.

Approaching it from the other side: The fiber diameter with coating but without any mantle is 0.25 mm. If you want to put 10 km on a 100 mm long spool you could put in 400 layers lengthwise, and each layer would have to be a spiral of 25 m (of course you'd spool it outside in, not layer by layer, but should be mathematically similar enough). Using this spiral calculator and some random changing of the values it looks like an outer diameter of 91 mm (3 & 5/8 inch), and inner of 15 mm and a thinkness of 0.25 mm would work for a 25 m spiral.

Or if we go for 125 mm drum length, so 500 layers, with 20 m each we get 82 mm (3 & 1/4 inch) outer diameter.

Or if we go for 150 mm drum length, so 600 layers, with 16.7 m each we get 75 mm (3 inch) outer diameter.

So yeah I think your estimate was pretty spot on, if the 10 km length is the right assumption.

Today's wires aren't actually wires, they are optical fibers. It must be G.652 or G.657 from telecom use, since that's commercially available en masse. I think most likely would be G.657.A2 because that can be bent tighter. Here's an example data sheet from a random google search. I wrote it in a different comment already, but the core has 9 micrometer, the cladding 125 micrometer and the coating 250 micrometer diameter. For telecom applications you'd add at least a mantle, or more likely use a cable with many fibers in little pastic tubes wrapped around a metal core for stability, 12 x 12 is fairly standard. Here of course it's just a single fiber without mantle being spooled off.

Bidirectional transceivers (so both directions on a single fiber) can do 100 Gbit/s ethernet too. No way you'd do that for drones of course, but just to show how far you can get with a single fiber.

bend the fiber around a pencil and only experience degraded signal

Interesting. Are you using G.657.A2 then?

Those news are already not so new any more. We've had reports of those two months ago.

Since fiber optic wire guided missiles exist it's not that much of a leap to think it should work with drones too, so long as the weight works out.

Fiber is really really thin. 9 micrometer core diameter and 125 micrometer cladding diameter (incl core) and 250 micrometer coating diameter (incl core, cladding). The 10 km spools we use in our lab for network equipment testing are boxes of only like 20x20x10cm, and those aren't optimized to be extra small with bend insensitive fiber. I can totally believe the 1.2-1.4 kg for 10 km in the article.

Edit: leak -> leap

I thought they were threatening him with flowers? He must be reading too much into it.
