I'm sick and tired of comments using the pop density excuse being an insightful.

Newsflash: fast broadband did not appear in the entire country overnight. Countries started with the largest cities, giving the maximum number of people access. South Korea has 80% urbanized population, same as US. If all urban areas has broadband on par with South Korea, the average speed would be similar to South Korea. But it's the people saying that we shouldn't do everything unless we can get 100% in one shot that's holding us back

In my experience, in the world of business, it is when someone in management finally snaps that you'd get the computer upgrade. If you write the business cases now, they'll just sit around getting outdated until the snap. Might as well wait for the snap, so you can write more updated business cases.

Comment Use CodeChef (Score 1) 407

If you have not done so already, I would recommend using http://www.codechef.com/ as a source of practice tests for your students, it has tests in various degrees of difficulty and CPU limit. As many may have mentioned, programming competitions tend to have different CPU seconds for compiled lang like C/C++ and interpreted lang (Python, Java). Codechef does something similar, though you may want to check if the difference is reasonable for the competition you're preparing for.

Also, the site has a lot of foreign participants and daily ranking for benchmark tests, this way your students can see where they rank and you can help them improve.

As for language choice, I'd choose Java if you wish to orient your students to a more collaborative projects, or Python for more solo projects. Most other languages on your list have various problems listed above by others and won't get the students as far as these two would.

Given that the dome will be a mile high, the idea that the dome surface will be less than that of house surface is rather unrealistic. At max, the roof area will be the full base of the the dome base, in, which the only walls will be along the base, by definition it will be of less unless the building heights are avg 1/3 mile high.

In reality. building roof coverage is significantly less than half the area of the region in all but the most densely populated cities. So, even though there are four additional sides to account for in most houses, it's not practical to consider that it will be able to overcome the surface area of such a massive construct

I must have taken a dumb pill this morning. I don't see how the square cube wiki article applies to the heating issues? Are you agreeing with GP that the heating bill will be worse or somehow will be lower heating bill? All the wiki seems to say is that there is more volume to heat, so there would be higher heating bills like GP was suggesting. Did I miss something?

Also, why would outside surface temp not drop below freezing?
