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.

... but how do they know if a phone is being tethered?

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 ;)

Submission + - Is Silicon Valley Over? (

HaveNoMouth writes: Paul Carr writes in TechCrunch that Silicon Valley is no longer where the real tech innovation is happening. Instead, the valley has filled up with cargo-cult Zuckerclones. Carr describes a recent party where he struck up a conversation with an entrepreneur who claimed he was creating a billion-dollar company:

It was only then I noticed his outfit. Everyone else was in smart-ish jeans and shirts, but the entrepreneur was carefully dressed in a hoodie and a pair of open-toed flip flops. Later investigation would reveal that his 'billion dollar' app was a social network for people with .edu addresses. The secret sauce? The fact that it gave college kids a way to flirt around campus.
Any of this sounding familiar? All he needed to complete the picture was a couple of embittered rowing twins baying for his blood...

Carr says the real tech innovation is happening in places like New York where old media is dying, where people take risks because they have nothing left to lose.

Personally, I think that in the future "computer science" won't really be a separate field of endeavor - like walking or throwing a ball or writing a report, it'll just be something people do without spending too much time thinking about it.

Of course it will still be a separate field of endeavor. It's just misnamed. Remember what Dijkstra said: "Computer science is no more about computers than astronomy is about telescopes."
