Stereo lithography has (had?) been used for decades to prototype various 3D parts for fit and interference, though it could not make structural parts, certainly not for high temperature applications.

SpaceX's SuperDraco engine is completely 3D printed, although I'm not sure of the exact technology.

So when do they release these 322 pages of new rules? With all this transparency, what could POSSIBLY go wrong?! /s

From TechDirt:

"First, it's important to note that despite a 3-2 vote approving the Title II-based rules, we won't get to see the actual rules today. Despite claims by neutrality opponents that this is some secret cabal specific to net neutrality, the agency historically has never released rules it votes on (pdf) until well after the actual vote. It's a dumb restriction that's absolutely deadly to open discourse, but it's not unique to one party or to this specific issue."

There's only one place in the article that specifically mentions mobile broadband. The rest talks about the internet and broadband in general.

Although it's not completely clear, I'm assuming Title II will apply to both mobile and non-mobile broadband, but he's calling out mobile broadband because the most ignominious examples of abuse (data caps, throttling, prioritization, etc) have been by mobile operators.

Electronics? Really? Those are just things. They can be replaced.

There's electronics and there's electronics.

Sure you don't care about your computer, TV, DVD player, etc, etc, but you might want to add a crank/solar AM/FM radio, flashlight, spare cell phone and maybe even a battery-operated TV to your stash.

Extra points for a CB or Ham radio.

Depends on whether your flashlights are compatible with lithiums. For example, they will cook a maglight with incandescent bulbs. The bulbs burn out within 10 minutes.

You're thinking of Lithium-Ion batteries which are nominally 3.6V.

Energizer Lithium batteries are 1.5V and are compatible with most electronics that take AA or AAA Alkaline batteries.

this kind of ruling encourages multinationals to never set up business in the USA.

I'm not sure it's quite that bad.

IANAL, but I can imagine a foreign corporation setting up a wholly-owned subsidiary in the USA.

Of course US operations would be subject to legal warrants and subpoenas, but all foreign operations should be outside the reach of US legal authority.

If a warrant is served for data from the foreign operations... sorry, the US subsidiary doesn't have access to it. It doesn't matter how many people they throw in jail for contempt.

But what do I know.

That is, if you're going to send a remotely guided robot to the moon, is a bipedal walker the best choice?

As opposed to a conventional wheeled or even a quadrupedal rover.

I assume a bipedal walker is going to need sophisticated stability control (computational and mechanical) for every step it takes over rough terrain that a simple wheeled vehicle can just roll over.
