Comment Re:Which means (Score 1) 347

Also, there's a semantic looseness as well that bothers me. The proposed solution doesn't really require changing the speed of light in a vacuum. Rather, it points out that photons will undergo certain interactions which mean that light as a bulk phenomenon will appear to go slower than the maximum speed light can travel in a vacuum because of those other interactions.

When computing relativistic effects, such as Lorenz contractions, etc., the upper speed (not including all those interactions) still remains the limit, at least as I understand it.

"Hey Paolo! He broke the President!"

I remember many years ago reading an article (probably in Wired; these days, it'd be a blog post) where someone described walking around EPCOT Center while listening to this exact album. Sounds like quite a trip, really.

And then there's this article from several years ago that's also fitting. Apparently Disney was working on their version of the Holy-Grams too..

It's like there's some strange black hole of information available on the internet that only happens around the super specific topic the Ask Slashdotter is interested in. I'm pretty sure all of these folks are the ones that were our best horses in Keener Bingo:

Ding ding. Fuck, C# is fine and dandy and pretty fucking fast, if your target platforms and related asset and tool ecosystems are cool with it, and you're not boneheaded about what you're doing. Questions like these are so silly - if you do so much homework to know what you know and what you don't know, I'm pretty sure you're smart enough to find the right information, books, etc. What a passive aggressive inquiry. If you're convinced you can write an intelligently framed question with tons of context, then why on earth can you not do a little google mining for books that focus on C# game development? This discipline is hardly a secretive cabal.

TOR quite simply does not work in China. I find it hard to understand why so many people here cannot see how easy it is to recognise protocols connected with TOR, VPN, Proxies, etc. and block any user that uses any forbidden protocol. None of these things work, not because they block the hubs or the addresses but because the they block the protocols.

Oy, is that how they're selling it? As if none of these features existed before Apple did it?

Swift code is transformed into optimized native code

As is any other language that passes through an optimizing compiler that outputs native code. They crowed about a 30% speedup above, which in my experience is sometimes achievable just by tweaking your compiler flags.

So many of my books only work on certain platforms :|

I can't read a bunch of my books on my glorious 4k screen because Amazon's treating Windows 8 like a second class citizen. Peter Thiel's new book? Nope. Half my machine learning books (eg Blondie24?) Nope. Most of my typesetting books? Nope.

Even stuff that works on Windows 7, or on Windows 8 Phone, ffs.

You realize, of course, that a 26" 1920x1080 monitor is only 85 DPI, so the same font size (in pixels) on a 26" 1920x1080 monitor would actually look about 40% larger. And, you'd get more text on the screen to boot.

1280x720 at 120 DPI makes for a small screen: 10.7" x 6", which is approx 12" diagonal. Do you do all your coding on a subnotebook or MacBook Air or something?

Well, they don't magically get cheaper to build just by building more. They get cheaper to build as the manufacturer refines the process, improves the technology, and scales the production lines to amortize the fixed costs of a production facility over a larger number of vehicles. That is, it takes work to make them cheaper, above and beyond just making more.

As long as there's sufficient demand, producers will have enough reason to scale up the production and work to bring the production cost down. Eventually, if all goes well, this begins a virtuous cycle where decreased price increases demand, and increased demand drives further cost reduction and innovation.

This works great if there's enough demand to kick-start the process. Unfortunately, the price of EVs today is too high to drive sufficient demand. Hence the carrot-and-stick incentives to try to jumpstart the virtuous cycle. On the carrot side are tax breaks and government subsidies / loan guarantees. On the stick side are fleet-wide fuel economy standards, price caps and quotas.

Right now, it seems as if most traditional auto manufacturers treat their electric cars either as halo cars, or as tasks they're required to do by law/regulation/whatever but would rather not. I doubt anyone at GM is staking the quarterly numbers on Chevy Volt sales, for example, but it doesn't stop them advertising it. The only competition at this point, though, is positioning, posturing and establishing a brand. That is, competition on the marketing front. The market's still too small to have meaningful competition driving the product development. At least, that's how it seems to me.

Eventually they'll figure out how to bring the costs down. Meanwhile, the early adopters hopefully help build interest and therefore demand in the future. When that happens, I'd expect the real competition to start. You'll see Toyota or GM or someone get into the mega-battery business, like Tesla is currently. Or some other major, bold move like that.

In the meantime, the carrot-and-stick will push both the supply and demand curves to the right, elevating the total units shipped to a modest number until the market can sustain itself.
