Teaching algorithms separately from data structures is one of the biggest flaws in modern computer science education. It's impossible to reason sensibly about one without the other.
And what was the destructive capacity of the Navy in 2006 compared to August 1945? Hell, one Ohio class submarine has more destructive capacity than the entire Navy from 1945
A statistic that floated around earlier in the year when Argentina was grumbling about the Falklands again: one of the battleships that the British were sending to the area could fire, in one minute, more munitions than were fired in the entire 1982 conflict. I'd imagine that the differences between 1945 and now are even more pronounced.
One constant trend has been that soldiers are less expendable. In the first world war, sending men to walk slowly towards machine guns and throw a grenade if they survived to get close enough was their patriotic duty. By Vietnam, having large numbers of soldiers come back in body bags was politically unacceptable.
In the 1940s, Japan was flying aircraft loaded with bombs into American warships. A few years later, people realised that you could design aircraft for this purpose and make them a lot lighter and able to accelerate more if you removed the human pilot. They called them anti-ship missiles.
The fighter screen that fleets needed to protect themselves from aircraft in the '40s is now replaced by anti-aircraft and interceptor missiles (and dumb projectiles). In the next generation of ships a lot of this will be replaced by lasers, which reduces some of the resupply need (you can't run out of laser ammunition on a nuclear carrier unless your ship is so badly damaged that it's not a good idea to be anywhere near it).
Gradually, a lot of the roles for aircraft are being replaced by drones, which means that you need smaller carriers. They don't need to house as many pilots, they don't need as many support staff.
Another part of this trend is to replace reusable vehicles with single-use munitions. Fighters are more expensive than missiles, so you spend a lot on maintaining them. Drones are a lot cheaper, so you can afford to fly them for a couple of missions and then scrap them (explosively, near someone you don't like).
Comparing numbers, as the grandparent did, is completely meaningless. You may as well compare the size of the air force to the number of soldiers Napoleon had.
Oh, and libavcodec / libavformat are used in Android (and in a lot of iOS apps, as AVFoundation doesn't always expose useful APIs), as well as in desktop browsers, so they're a pretty good target to aim for.
Take a 450 page A5-ish paperback. Hold it in front of you with the spine horizontal & facing you, gripping it at the extreme left or right.
4 inches times 12 ounces.
Next time you're there look for a keyboard with a working shift key.
P.S. There's no plural of Lego, and even if there was it wouldn't have an apostrophe.
To the vast majority of the marketplace? The value is zero.
When you're making a consumer decision, do you ask yourself, "what do the vast majority of people do?"
Great, we look forward to seeing your new upstart-based distro, since everyone else has abandoned it.
