Nice as the Surfaces may be, I won't touch any Microsoft products for the next few years. Wiped Skype from my Linux and mobile devices too. Trust comes on foot and leaves on horseback, Microsoft.

Right now two of my kids (10 and 8 years old) are having fun this Easter Holiday learning programming in OpenSCAD (a CSG 3D CAD modelling language). Yes, even a girly girl can have lots of fun with this, designing a lamp, a cool name plate, and a funny 3D cartoon face (all with carefully chosen colors of course) - on the first day. And hardly notice how much they're learning along the way. OpenSCAD is not a toy at all but a great visual way to get started with some basic programming language concepts.

Palcohol is based on cyclodextrins as a carrier. Cyclodextrins are used for similar food/pharma engineering, such for making dry (and even water-soluble) forms of vitamin D.

Good point from TFA: " it’s secure because it never connects with a “NSA backdoored” computer when generating it", which actually makes sense. Many people have a calculator like this which provides a suitable air-gapped and safe computing resource.

It always amazes me to read the many derogatory comments on Slashdot about food supplements and other alternative health approaches, with arrogant snides about how these are 'unscientific' and 'unproven', and how dumb people must be to believe the claims. Believing pharma research results seems at least as dumb (as it seems to have little or nothing to do with actual science and I think this has been obvious for many years now).
