Comment Re:Why? (Score 1) 49

There was an effort in 2006 to re-create the Scott expedition to see if they could figure out why it failed (see the second paragraph of https://en.wikipedia.org/wiki/Comparison_of_the_Amundsen_and_Scott_Expeditions#Food_and_fuel). They called it off before reaching the pole because the expedition members were suffering from severe weight loss.

According to the OpenBSD link, OpenBSD uses the Intel and Via random-number generators, but not as the sole source of randomness. The nice thing about mixing random number generators is that if you do it right (like OpenBSD does), the result is at least as random as the most random source: a bad RNG does not reduce the overall quality of randomness.

What's funny is the ones who say communism is a good idea that just hasn't been done right never really pay attention to the times it has been done exactly according to plan and still failed anyways.

Communism works just fine on a small scale, where everyone involved can see all the "ability"s and "need"s. It's a good bet, for example, that your immediate family operates on communist principles.

Depth perception has over a dozen components, of which stereopsis (your "normal binocular part") is one of the weaker. People have trouble with 3D in movie theaters (and will probably have trouble with the Oculus Rift) because two of the stronger components (accommodation and convergence) are giving very different depth signals from stereopsis. This technology has the potential to be accommodation- and convergence-neutral, meaning the strongest depth signal comes from stereopsis.

But we can't do anything magic to fission products to make them decay into something stable any faster

Actually, we can. Neutron bombardment will usually create particles that are less stable, so they take a faster decay chain down to a stable state. It's a tradeoff: your radioactive waste becomes more radioactive, but for less time.

Comment Re:Helium? (Score 1) 429

Maybe. On the one hand, if 100% of our electricity comes from fusion, that works out to around 100,000-1,000,000 kilograms of helium produced each year. On the other hand, the amount produced per reactor at any given time is minuscule, and would be a pain to try to collect.

No:

Boston and Washington DC will have merged into a giant city with 40 million inhabitants

He came close, though: he underestimated the population of BosWash (it's just shy of 50 million), and it's still a group of distinct governmental entities rather than a single unit, despite being a continuous urban area about 300 miles long.

The biggest sign of a vanished high-tech civilization is not a presence, but an absence: a near-total absence of high-grade metal ores. Probably the best evidence that humans are the first widespread technological species on Earth is the presence of high-grade iron ore spread across virtually the entire world.
