Comment You need a new doctor (Score 3, Insightful) 464

Look at what happened here: You needed new glasses, your doctor suggests progressives, which you try and don't like. Then, instead of approaching your doctor about the issue, you post on /. instead. Maybe you're just looking for a second opinion, but it sounds like you're not comfortable talking to your doctor. You should find a doctor that you can bring up these issues with. Also, your doctor should have asked you about what you do all day (reading the iPad, using your computer) and offered you choices based off of your health and habits, not just your health alone. Just my two cents.

Yes, it is an alpha emitter. But it and its decay products also produce plenty of gamma. See http://www.csupomona.edu/~pbsiegel/decaychain/U235.html . You build a detector to detect the gammas at the particular frequencies that U235 emits at and bam - you've got a detector that will detect U235 and nothing else. Also, gammas are highly penetrating, so unless that cargo container is lined with a significant amount of lead, you will detect something if its there.

Comment Sounds good to me (Score 1) 86

I ended up in Tsukuba a few years back in the middle of the night, lost, with no GPS, and I don't speak a lick of English. I finally found a bus station and waited for a half-hour in the cold before one came by. I got on and it was just me and the driver and he spoke no English. Finally, by sketching out landmarks near my hotel, he managed to figure out where I needed to go and let me off at the nearest stop with some gestured-directions.

Anything that would have made that experience more pleasant is gladly appreciated.

Not as much as you think. Using lightbulbs to heat the air near the ceiling, where hot air naturally convects to anyway, is just a waste. Only if you have a way to efficiently recirculate air from around the light fixture to where you're at will you see a benefit. Otherwise, most of it will be lost up to the attic and then outside.

I've been with openSUSE since the 8.x days and I've had multi-monitor the entire time. As I recall, 10.3 was good, as was 11.1 and 11.4. 12.3 has been excellent so far, especially since it is really more of a service pack for 12.2.

The problem with your argument is the "2.5 million years". That somewhat arbitrary timeframe allows you to make the argument that high-fat meat-based diets are ideal. However, if you consider the "diet" of all of our ancestors back to the dawn of life on Earth, roughly 4 billion years ago, you'll find that most of our ancestors over that time were simple organisms that ingested simple sugars - a diet that would kill us today.

At the other extreme, our species has only existed for around 50k-200k years and if we've been eating grains for 10-20k of that, then we've had grains in our diet for around a quarter of the time of our existence.

Either way, its hard to infer what we should eat based off of what our ancestors ate. They weren't us and we're not them.
