I've gone through three Roombas and won't buy any more. They take too much care and feeding -- even the ones that automatically recharge themselves. The reservoir is too small so you have to dump it too often, and after a year the battery won't hold a charge and you have to replace it -- for $100. And you periodically have to take the whole thing apart because the moving parts are all gummed up with cat hair. (You have to do this even more often if you actually have a cat.

Just get a Dyson and use it. It works.

I also put fiber in my walls. Not just fiberglas but glass fiber. That was ... overkill. I use the CAT5; I don't use the fiber.

Yeah. 12-gauge wire rather than 14 for all power outlets has saved my ass numerous times. (Coupled with a 20-A breaker rather than 15, of course.)

There's already a lot of DC power transmission going on, especially outside the United States. You don't need superconductors for this; you just need high voltage and power electronics. With superconductors, you can do DC transmission at low voltage.

The only location-aware app I want is one that tells me how to stay far away from Adobe and its crapps at all times.

Well there's a first. A robot dog just made me cry while reading Slashdot.

...matter of fact it's all dark.

Do I get a pony?

Several possibilities:

1. User-agent sniffing. Remedy: Change the UA string on your laptop's browser to match the one on your phone. Downside: Be ready to surf crappy "mobile-enabled" sites on your laptop.
2. Deep packet inspection. P2P protocols etc are unlikely to be coming from your phone. Remedy: Use a VPN or an SSH tunnel.
3. Traffic volume. Statistically higher traffic volumes suggest (but do not prove) tethering. Remedy: Use fewer bits ;)
