Navy Uses Railgun To Launch Fighter Jet 314

Phoghat writes "In 2015 the aircraft carrier USS Gerald R. Ford will take to the seas and the plan is to use a railgun to launch planes, instead of steam powered catapults. From the article: 'The Navy developed its Electromagnetic Aircraft Launch System as a replacement for the steam catapults currently used on aircraft carriers. The EMALS is a linear induction motor that's capable of accelerating a 100,000 pound aircraft to 240 miles per hour in the space of 300 feet. Compared to a steam catapult, the railgun catapult is much smaller, more efficient, simpler to maintain, gentler on airframes, and can deliver up to 30% more power. It's also capable of being cranked down a whole bunch, meaning that it can also launch smaller (and more fragile) unmanned drones.'"

Maybe the fact that the Romans and the Mongols never tried to conquer Afghanistan was the result of an intelligent reticence. Even in the Byzantine era (who still called themselves "Romans") when Heraclius more or less replicated Alexander the Great's feat of conquering the Persian Empire, he promptly turned around and went home without touching Afghanistan.

But like an earlier comment mentioned, as ruthless and (in my opinion) needlessly violent as the USA's recent conduct as been, the Romans would not have tolerated an insurgency. I once heard the journalist Seymour Hersch (I probably misspelled his name) allege that in the Project for a New American Century circles such as Dick Cheney and Donald Rumsfeld, the Third Punic War is bandied about as lot as an example of what the USA should do (As in, after two huge wars against Carthage, one of them involving Hannibal running riot across Italy for ten years, the Romans had effectively cowed Carthage into little more than a vestige of what it once was. When there were rumblings of possibly a third major conflict, the Romans responded by simply killing everyone they wanted to, selling the few survivors into slavery, and famously sowing their land with salt so that nothing would ever grow there again.)

I'm reminded of a great quote by the grouchy Roman historian Tacitus - "The Romans make a desert and call it 'peace.'"

His parents had to go to someone else's house to see his performance in the Tour de France because they don't even own a TV.

Wow, so devoted to their lifestyle that they have to go all the way to their neighbor's house to breach it! I may get modded flamebait for this, but seriously, what does their objection to that technology even mean if it can be so easily disregarded. Oh, God doesn't mind or isn't looking if it's for a special occasion? How do they know? And if so, then why can't they just own a TV and call every day a special occasion?

I'd have more respect for them if they simply didn't own a television by choice and watched it at their neighbor's place, rather than out of some showy religious gesture.

Also check out Throne of Blood, Akira Kurosawa's samurai adaptation of Macbeth, in Japanese, with a few minor story alterations, and naturally none of the original text.

And while a scottish guy who happens to be black would be fine in a production of Macbeth, it's a little naive to think that race could or should just disappear. In modern settings and contexts, in multiracial countries where race and nationality are distinct, then casting should be colorblind, but in productions set in certain historical settings or in racially homogenous societies, it wouldn't work.

Fwiw, Adobe already /has/ open-sourced Flex, the Flash framework that really makes Flash useful for developing RIAs (they haven't open-sourced their compiler, I don't believe, but all of the Flex ActionScript is available). I'm a Flash/Flex developer, and at least a few times a week I grep through their source code to figure out how to do something, or how to change something about a built-in component, etc. Adobe has also released a specification for their swf file format, available at http://www.adobe.com/devnet/swf/.

Oops.

I was mentioning it in the original post just based on my memory of when it originally hit the news, and responded with a TheRegister article that I got form a quick google search as I was heading out the door. I must have missed the retraction at the time and all that had hung in my memory was the initial controversy (which probably made sense to me given their somewhat controversial entry into the Mainland Chinese market.)

So, I'm sorry I cited that as an example, though I DO think it still stands as an example of Google Maps causing a political fracas, the fact that it was amended doesn't REALLY eliminate that point. Anyway, thanks for the correction.
