Ask HN: What happened to the cell-towers targeting Android phones?

How could citizens of the affected areas find out who owns the land -- the state should have that information right?

Who owns these towers? Since they're supposedly near military bases, these could be military or spying operations against the military!

Ask HN: When are we getting better batteries?

1 points|adamb_|11 years ago|0 comments

I've read countless stories over the past decade of amazing strides being taken improve battery performance in the lab. What's slowing these solutions from coming to market? Large-scale manufacturing feasibility? Not enough R&D? Regulations?

Simply put, when should I (average consumer) anticipate being able to purchase a laptop with a battery that goes +2 weeks without charge? ~10 years? never?
