"... football-field-long ovens for drying layers of material that have been dissolved in solvents..."

Hyperbolic language meant to spur some sort of emotional reaction, I guess?
This process : deposition of a dissolved solid and then the solvents being driven of by a long, gentle drying process, is pretty common in industry as a method. For example just about every self adhesive product uses this process for its release coating.

Why would you do that? If you're using it for non-strings, you'd never have used strncpy, you'd have used memcpy. Which is the same thing without the null termination rules of strncpy. You'd never use the str versions unless actually working on strings.

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...

Comment 3D printing whole rockets was such a dumb idea. (Score 1) 47

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 4, Insightful) 47

"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.

The funny thing was that I knew him for like six months online before I realized he was fully paralyzed. He's been covered in the Finnish press a number of times. Amazing guy. Up until recently he was living in a house he built himself before ALS struck, but the medical service decided he was too far away and he had to move closer. You lose a lot of control over your life with ALS.

He wrote a book about nuclear safety engineering recently, which is a fascinating read, and which I strongly recommend.

"the American rightâ(TM)s hostility to democracy" you say?
Do tell.

So if we're talking sides, which "side"
- invaded social media spaces, and then emplaced high level government agents within the relevant companies SPECIFICALLY to guide "public conversations" in the directions they prefer?
- pushed for vote-from-home, the most beautifully-crafted system if one wanted fraudulent voting?
- pushed for electronic voting, again simplifying and enabling large scale fraud?
- manipulated information, media, reporting and hid any information that called into question the mandated "It came from bats" COVID theory? And then worked hard to kill/hide the fact that the US actually funded gof work at the lab it seemed to come from?
- spent years telling us how far apart from each other we were allowed to stand?

I don't think Trump and his crew of morons is any better, but the idea that one side is better than the other is laughable.

Some would agree that yes, what was going on was inexcusable.
