Comment Re:3D printing whole rockets was such a dumb idea. (Score 1) 46

Oh god. If I spent enough time digging through my ancient Slashdot posts, somewhere back there there are posts of me going, "While I loved the strategy behind Falcon 9, I'm really not keen on this plan to make Starship out of huge carbon fibre tanks, that sounds like a really failure-prone solution..." I'm glad they only spent like a year on that idea before deciding it was dumb; somewhere back there there's also a bunch of posts of me cheering their switch to steel ;) . SpaceX still keep having random COPV problems (most of which they don't even make themselves). Not too encouraging for the notion of the cold gas thruster add-on to the Roadster, where the plan is to replace the back seat with COPVs, so you have a COPV right behind your head.

Electron has been getting by on CF, and honestly I'm impressed, but they've also been only working with very small launch vehicles thusfar. We'll see how neutron goes...

These activities alone should disqualify a site from Section 230 protections.

Removing section 230 protections isn't the fix. Once you start opening that door there's no closing it. It absolutely will be done unfairly. Algorithmically displaying content has legitimate uses. The question is, how do you regulate only the harmful ones? I like seeing what I'm looking for, so I want algorithmic content, I just don't want the algorithms to be designed to make me feel bad.

DEF systems on heavy vehicles work, but they're fairly, well, heavy.

They aren't. There's a reservoir, a pump, and an injector, besides the SCR. But the SCR is already present, it's just a little different in systems with DEF.

Among other thing, they use electrical heat to get up to operating temperature.

That's for freezing conditions. There's a resistor in the reservoir, big whoop.

Then there's the issue of needing the fluid. For earthmoving equipment and railway locos, they'd rather not deal with that and have gone with complex EGR systems with liquid cooling instead.

Cooled EGR is not an either-or to DEF. You can have both.

Indeed, it's extremely laughable to think that Muslims are all Democrats, when they are part of a conservative faith. It's exactly like believing that evangelical Christians are all Democrats.

Unfortunately, most people aren't going to take the step to figure out that their conservatism is just like the conservatism of the people rejecting them.

Whether you like it or not, social media is the new public square.

We can and should regulate how the creators of social media networks take advantage of their positions of authority and control. There is absolutely, positively, and in every other way no reason why we can not or should not do that. There is no principle under which a hands-off approach makes sense.

If it is known that social media harms kids, then doesn't the state share some of the blame? Why is there no law?

The gears of justice grind slowly. This is by design. When you go fast, you break things. And also, no. The state didn't make them do it.

If it is not known (or only recently came to light), can you really blame the social media companies?

Yes, you could. But that's not the case. They know and have known. We've talked about that here a bunch. They willfully conduct psychological experiments on users and monitor the impact.

If the harmful effects were known to the companies and they kept it quiet, then you'd have a case, morally speaking.

That's why there's a case... no, wait, thousands of cases.

Facebook willfully psychologically manipulates people into vulnerable emotional states in order to increase engagement, they take advantage of that by knowingly spreading false information and have actually reduced the number of people they have working on reducing the false information and replaced them with automated systems which produce false positives which punish users who are conforming to their rules and standards, but seemingly do nothing to prevent actual violations.

Comment 3D printing whole rockets was such a dumb idea. (Score 1) 46

Don't get me wrong, there's a lot to say about printing small rocket parts, such as for the engines. But they were printing basically sheet metal cylinders, which is such an immensely slow and inefficient way to go about it, and it left them with parts that were heavier and less aerodynamic (rougher surface). Crazy that idea ever got any funding.

Comment Re:Anyway SpaceX is a huge scam so I suspect (Score 3, Insightful) 46

"SapceX has got to be a huge scam too" - SpaceX launches the vast majority of the world's commercial cargo to orbit. The Falcon 9 FT has the highest success rate of any rocket with a statistically significant number of launches under its belt, and is dirt cheap. SpaceX's core operations are roughly breakeven, but that's including subsidizing the development of Starship. Starlink is a money printer.

There are lots of things sketchy about the SpaceX IPO, to say the least, but SpaceX, as a company, has been extremely successful with rocketry.

A thing that often gets missed is that a lot of Adobe's users are extremely non-technical. They did not learn how to use graphics software, or DTP software; they learned how to use Photoshop, or InDesign. My mother was not a stupid person, but she was basically allergic to technology, and yet she managed to transition from doing physical pasteup with hand-done separations to working on a Macintosh and using Illustrator and Pagemaker. (This was long ago enough that Aldus was still a thing, and the Macintosh was a IIci with 5MB and a 8*30 non-GC card to run the Mac Two-Page Mono display.) And while InDesign is not quite as easy to use as Aldus Pagemaker was, because it does more stuff now, it's still quite comprehensible. I've used it for some projects, and it was still easy enough.
