Re: Not useful
It might also be difficult to motivate Taiwanese engineers to keep working for you.
You can't exactly put their families in a Gulag until they comply - Amazon have a patent on that

> Virgin are doing something new, using air-breathing jet engines to add height and (crucially) speed to a payload.
Pegasus have been doing it for 25+ years.
It adds very little speed and none of it vertical
It adds 40,000ft, out of 100km, height - not enough to allow you to optomise engine nozzles for vacuum
It's main advantage is that you can launch from regions like LA, where they wouldn't let you set off a rocket, and you can get above local weather to some extent.
Haven't followed the Bearded Ones "efforts" so much
Does this air-launched vehicle have any path to actually being orbital?
There is a big difference between boosting a rocket cockpit to 80km before dropping back and doing 10km/s sideways to actually orbit

Replacing a CEO with a cartoon character has a lot of advantages
Lower salary costs, no need for private jets, no embarrassment when they take a private jet to beg for bailouts / to promote being environmentally friendly.
Greatly reduced incidence of sexual harassments (except Roger Rabbit)
Reduced chance of racist outburst (except early tom+jerry)
Less likely to do something stupid in public destroying the company (except W.E. Coyote)
>I don't know if that applies to software. But it sounds like it should.
That's where it gets complicated.
If the software was created by Nasa from scratch, yes
What if it includes a numerical library, what if that library is built on another library and so on ? (hint all numerical libraries are ultimately BLAS)
What if it calls a NAG or Matlab routine, those libs aren't opensource but what's the copyright on the calls to them? Is it open source to call a commercial library? Are the argument names to a commercial library function proprietry?
The UK's official astronomy software used commercial NAG libraries under a national academic licence that came with such onerous terms you weren't allowed to even show your results to non-UK collaborators.
Until everybody just switched to using free Nasa-Space Telescope software instead.
Just so long as you don't have any of those big long red tube shaped fuses at the end.
Not joking, we had a high voltage power supply to a flash x-ray (what the kids today call an x-ray laser) where the connection from the bunker full of capacitor banks to the head was a glass tube full of copper salt solution wrapped with explosive tape.
It's rather difficult to turn off 10,000A of high voltage DC with your typical 2 pole switch.
There was a 'backup' mirror blank made but never polished.
It's in the Smithsonian (or it was last time I saw it)
This is normal practice for large or expensive mirrors - sometimes things happen in the grinding or polishing, a flaw is discovered or an accident takes a chunk out.
Zeiss made a spare 8m mirror blank for the VLT (made 5 used 4) that they were trying to sell off to anybody who needed an 8m mirror - don't know what happened to that, probably got melted down.
> have standard best practice processes
We had that, "standard best practice" was that all the IT infrastructure was to come from a single supplier. Naturally the only supplier that could offer mainframe + mini + workstation + PC (back in the 80-90s) was IBM.
So we had a single "integrated system" that had an IBM mainframe running God-knows-what, AS400s for HR and accounting, RS6000 unix workstations and PS/2s for student desktops.
Strangely this didn't all work together seamlessly and was gradually abandoned. But only after getting rid of all the sock+sandal wearing beardies in this basement that knew how everything worked before.
