This isn't about the addiction potential, only about the purity. And I wasn't exactly serious.

I don't think so. In university some pharmacy or chemistry guys could scrounge pure ethanol. (98 or 99%.) Screwdrives with that were nasty.

There are several examples of formerly brilliant people who lost their marbles in old age.

Lots of climate change deniers, cornucopians and similar delusional folks in software development.

I wish I had mod points to upvote you. This whole discussion is so US centric with Puritan morals :(

...now that Apple and Pearson's got the money.

Looks like they need a new project somewhere else.

Dark matter might be amassed slower than ordinary matter though because it's not slowed down by the accretion disk and similar processes that get rid of momentum. IOW, a particle has to be headed directly into the event horizon, otherwise it'll miss and continue to orbit.

There are drive-by downloads from ad networks which you'll catch with a standard setup.

Running Linux and tightening up your browser should be good enough.

And I'm good at it. Usually flies.

A file server with a reliable disk subsystem and file system that is maintained well, or a company that probably won't be around any more in 20 years?

I still have some superfluous debugging code in a project that literally does nothing in the production version but without it the code crashes randomly after a week or so; a classic Heisenbug. It's clearly data trashed by a wild pointer but I could never find who did it since it's a large multithreaded program that depends on hardware behavior. Neither valgrind nor Coverity were of any help. It's too big to be rewritten so we just have to live with it.

Accept the walled garden. Even if you find a fix now Apple will probably break it with the next release.

I'll tell you this, it's way more difficult and far more expensive/time consuming than you might imagine. You should also be very clear about your reasons for doing this, keeping the kid at home is not one of those reasons. I know several homeschooled kids like that and they're a bit stunted, you have to make sure to get out and be active a lot more as well. Look around in your area for enrichment programs, for instance our kids go to public school 1 day per week. It's fantastic, and they make a lot of friends plus get that more structured school environment. Make sure that you're doing this for the right reasons. Finally, it takes an unbelievable amount of discipline from you both as parents. My wife and I are up late hours every week making sure that we have lessons ready, making tests, basically doing the things normal teachers do. If you're still reading and serious about this, it's also very rewarding. Seriously, if you do this right your kid will be light years ahead. You do it wrong and you'll really fuck up your kid's future.

I bought a Banana Pi as a download/torrent box. Only slightly more expensive (especially if you include shipping) but with a SATA port that gives me about 60MB/s. And it runs Raspbian.
