Reply to comment by Tamariniak in Best way to run PC fans from outlet? by Tamariniak
Yup.
Couple of additional things to take note of. You do not have to run the fans at 12 volts, if you run them at lesser voltage they will spin slower, an thus be quieter (if that's important to you). Though there is usually a minimum voltage that they will not operate under.
You will also see talk about 3-pin and 4-pin fans. Don't worry about it. For your use case, ie running it of a separate power supply, it makes no difference. The 4th pin is use for PWM (pulse width modulation) which is a different way to modulate the fan speed. If you're not using it 3 and 4 pin fans operate exactly the same way.

Reply to comment by GalFisk in ELI5: in MS-DOS there were not-interchangeable audio cards and we had to manually select it to get sound, otherwise there was none at all. When and why this stopped being a problem? by 3RBlank
>There were a few standards
There were, but the only ones that I remember were "Soundblaster" "Soundblaster 16" and "Soundblaster 32" that were only standards because those cards were very popular so most games would support them. So competitors made their cards compatible with that interface.

Have you seen the custom 4 rotor Rob Dahm is building? Well built, currently tuning it.

RTG's also tend to use isotopes with a much shorter half-life (since they decay faster and produce more energy). So while they can last years/decades, they don't last the centuries/millenia of nuclear fuel.

No no. This is a good visualization.

and can only be used in short bursts.
The only engine ever designed to run on continuous after burner was the Pratt & Whitney J58 on the SR-71 afterburner. Though the J58 acts more as a ramjet with a turbojet stuck in the middle.

Those are ususaly to prevent damage due to too high pressure/temperature.
In a turbo fan there is air that is deliberately bypassed with the intention of adding to thrust.
One way to look at turbofans is that they are turbojets with an additional fan on the front to accelerate more air. So the point of the turbojet is now not to accelerate the air, but to power the fan that accelerates the air.

In this case it sound like rough handling and a rough road. It's case literally shook apart in transit.
As for what it was use for, it was probably a calibration sample for a piece of detection equipment. An known quantity to ensure the device is reading properly.
As for how dangerous, the worry is more only if it is kept near someone for a prolonged period of time. Especially if it is kept on their person. So they are more worried that someone will for some reason keep it.

Aesthetics are fine, as long as the book and text is readable.
Don't do pictures, do line art. Pictures and shadeing don't really work with the printing most books use.
If you are going to have maps/diagrams/charts. Make sure they are legible. Too many times I have seen fine details get lost because it was too fine for the printing process.
A good example of good maps is the Wheel of Time Series. The hard covers have on their endsheets a beautifully done, full colour, shaded map of the world. But a few pages into the bookblock is (ususally) another map of the world. Showing the same area, but done in lineart. So same details, but perfectly legible. Where as a scan of the full colour version attempted in grey scale would have been a mess.

There is not usually an actual policy.
It's the fact that if a division shows that it can do the job with less resources then given they will be given less resources in the next budget, because why would it need more? it's shown it could do the job with less.
By spending the entire budget (even on seemingly stupid stuff) they can argue for the same or larger budget next time.

Reply to Should I read The Martian by Andy Weir even if I’ve already watch the movie and remember most plot points? by CaregiverBig7228
YES!
It is actually one of the few adaptions where I suggest the movie first and then the book. Because while it is a fairly faithful adaptation. And most the problems that he overcomes are in the book, what isn't in the movie is his internal logic on how he solves them. PLUS all the other obstacles that he has to overcome.
