you mean energy from the sun and some nutrients? Or do you mean energy in processing? I'm not sure you're proving much of a point either way. You do realize that it takes energy to dig oil from the ground? and then to refine it? Ya... I thought so..

So?

Oh, the things humans will do to get their grubby hands on gold—a metal that's mostly useless except for the fact that we've arbitrarily decided it's worth, uh, its weight in gold.

There are two things that appeal to me about Boston Dynamics. First, their robots are improvisational, meaning that every little movement isn't painstakingly pre-coded like you get with Asimo. So while Asimo has to deliberately negotiate a series of carefully placed steps Boston Dynamics' robots can practically…

Amazon has decided to not pursue delivery by quadcopter and decided to test a new method....however, this is in doubt after a test run terrified an entire city....

I know. It's perplexing that these videos are so deeply funny. I mean:

So anything that isn't the cheapest possible version of a product must be a paid ad now?

This is done on purpose. It's basically 'Planned Obsolescence' taken to its logical extreme; They NEED this road to fall apart before the next budget year is over, and what better way to ensure that it cracks open within 3 months than by laying asphalt on top of a layer of snow? Why do they need this road to fail, you…

Tip each time I ask for a drink? I could stay 2 more hours at the bar if I saved all those tips! I say one should tip not for the service you've got, but for the service you wish to receive. Here's why:

Tip is earned - there should be no rule-of-thumbs. I would think that these numbers are ridiculous for most of us readers.

Yeah...I'm not tipping more than a buck for a beer. Mixed drink? A couple of bucks. Three if it's strong.

Melanie's daytime job is a writer for Lifehacker. She's obviously a bartender at night trying to make up the difference for the LH pay.

this guy is boring. should have dropped it on a phonebook.

I feel like this list could have been shortened to "Just don't go shopping until christmas is over."

So basically... Only buy food?

The opposite, I'd think. You must have small ears but normal-sized ear canals. If you had small ear canals, you'd be like me. I can only do the Apple-style earbuds or over the ear. The in-ear ones are horribly painful, like someone is trying to rip my ear apart.

It's driving me mad that 'classical' earbuds seem to be disappearing in favor of the in-ear ones and that it's also so difficult to find ones with analogue volume control. I find in-ear headphones uncomfortable, and don't want to go around carrying over-ear cans all day. My Sony MDR-E829Vs broke down recently after…

I'm the complete opposite. Having 70+ tabs open at any given time is standard. I don't like that I do that, but I have this feeling of "Oh! This is interesting! I'll keep this here for future reference, I'll definitely want/need it soon." I have more than enough RAM, so it doesn't bother me much in that sense, but…

If you come back as a frog, watch out for Friday the 6th.

Or, you know, coincidence.
