Most people lack the bandwidth to be able to stream 720, yet alone 1080 video. A 1080p Blu-ray rip is usually around 10GB for a 2 hour movie. Streaming 10GB in 2 hours requires a connection speed of around 12Mbit/sec. 720p rips are 5-6GB,

802.11g or n is faster than most consumer Internet connections. Nobody's suggesting streaming HD movies over the cell network... yet. Blu-ray discs are 25-50GB, but they contain lots of stuff besides the movie (bonus material and other stuf

I find your comment both uncivil and insubstantial (to use terms from the HN rules). You found one tangential thing in the article and disagreed with it. You didn't explain why you disagreed with it, you simply crudely expressed your opin

That was a very good article, both interesting and emotionally satisfying. I didn't know it was possible for people to acquire language as late as their 20's.

The purpose of the reversal test is to eliminate status quo bias, not actually pretend the situation is true and offer better solutions. http://www.nickbostrom.com/ethics/statusquo.pdf explains it better than I can (around page 9).

Wikipedia has to fight entropy as well. They have admins and other moderators who enforce policy about what users can do. Becoming an admin requires spending at least several months editing, and collecting enough friends to get you voted in

The programming subreddit is sorta similar: http://www.reddit.com/r/programming I haven't found anything really comparable to HN. IMO, the quality of submissions and comments has gone downhill. It's a common problem of fast growth in a fo

I think it's more probable that the numbers in the infograph are inaccurate. We have no idea how the DOT did their survey.

When HeLa cells were first derived, most of the benefits weren't even on the radar. Excuse me? It was the first human cell line that could grow in culture indefinitely. Doctors and researchers immediately recognized the potential of HeLa

Her family was deeply disturbed by what was happening at first. Progress is necessary, but so is people's dignity. I don't want to be callous, but look at the cost-benefit calculation: Cost: One disgruntled family. Benefit: Polio vaccine.

The US population increased substantially over the time of that infographic. Using their figures and census estimates, biking trips per person doubled between 1990 and 1995, then stayed roughly the same since. Walking trips per person is we

The main reason for redundancy is because NASA can't send someone out to fix the probe/satellite, so the hardware has to be designed to work flawlessly for decades. Astronauts use consumer laptops just fine on the shuttle and ISS, and I dou

assume the brain dissipates 1/10 of this; 200 kilocals per day. The human brain is pretty hungry. http://www.pnas.org/content/99/16/10237.full says around 1/5th of resting human metabolism is to power the brain. So double all numbers in

This is also my favorite TED talk. Ramachandran has come up with some clever ways to study and heal the brain. His mirror box therapy is not only simple and effective, but his prerequisite theory was accurate yet initially based on a tiny a
