Testing membership is the easy part of sets. What about subset, superset, union, intersection, difference? So many problems are trivial thanks to sets. I'd sooner give up regex support in python than the set type, that is how useful

A steel wire can lift things all by itself. Just cool the wire. If you disagree with this, consider the motor or hydraulic cylinder that can't lift anything either. (Without an external source of energy like a battery or compressor.

The "big new thing" about this is that it doesn't use compressed air the way traditional air muscles do. It doesn't use compressed air at all. You're probably going to say that vacuum pumps are noisy/heavy n

What is your field? What textbook says that "microwave" and "radio" are different? I've been citing a lot of sources here. Just this one from you would be appreciated.

If you are worried about that, just don't use Crouton. Completely remove all of the Chrome OS partitions and run linux natively. I typically get several months of uptime. Suspend/resume has been flawless too. Pressing one butto

You'd have to add shielding to it too. The whole point is that a single large shielded Cycler makes a lot more sense than smaller ships.

Funny you should mention Mint. For many years they have required that you do a re-install instead of a dist-upgrade. Even just this past year, that was the officially recommended course of action for going from Mint 17 to Mint 18.
