Will Google's Dart Language Replace Javascript? (Video) 177

Posted by Roblimo
from the shall-we-play-darts-or-javascripts-this-evening-at-the-pub? dept.
Seth Ladd, Google Web engineer and Chrome Developer Advocate, is today's interviewee. He's talking about Dart, which Wikipedia says is 'an open-source Web programming language developed by Google.' The Wikipedia article goes on to say Dart was unveiled at the GOTO conference in Aarhus, October 10–12, 2011, and that the goal of Dart is 'ultimately to replace JavaScript as the lingua franca of web development on the open web platform.' A bold aim, indeed. Last month (June, 2014), InfoWorld ran an article by Paul Krill headlined, Google's Go language on the rise, but Dart is stalling. Seth Ladd, unlike Paul Krill, is obviously rah-rah about Dart -- which is as it should be, since that's his job -- and seems to think it has a growing community and a strong place in the future of Web programming. For more about Dart, scroll down to watch Tim Lord's video interview with Seth -- or read the transcript, if you prefer. (Alternate Video Link)

Are there really more methane-producing animals than there would be if there were no humans? Cows, buffaloes, deer, any other farting animals? I might be wrong, but it seems implausible that we would be responsible for the fact that there are now too many animals on the planet, quite the contrary. I do believe that we are responsible for the disappearance of vast amounts of forest that used to turn all these farts back into oxygen.

In European cities, the beeper may well be 5 meters (sorry, 15 feet) from your bedroom window. So yes, you WILL hear it even while fucking. Of course it's not going to be a problem on American mega-intersections with parking lots on all sides and the nearest home miles away, but some Canadian cities are (fortunately) more like European ones.

1. Increase of cost. Adding a pole for the near side would add cost.

Then add it to the far pole of the other side. Duh!

2. Looking down at the timer when you should probably just be looking at traffic. Alternatively, having the timer on the post with the "walk/don't walk" sign at least has you focusing near your path of travel.

Who says you have to look down? Just install it at more or less eye height so you can see it before you start to cross. Then, while crossing, you look at traffic instead of at the digits on the other side.

And it annoys the hell out of normal hearing people, especially those living close to an intersection. Please, there's enough noise as it is.

How about a very small timer that can be read by people standing next to it, waiting to cross? There's absolutely no need for it to be readable from across the street.

At times when the renewables production spikes, the electricity is "sold" at negative prices - i.e. whoever takes it, gets paid.

Why would suppliers provide electricity at negative prices? Can't they just waste it somehow, just install a bunch of resistors in a big swimming pool and run the excess electricity through there?

Of course storing it for later use, for example by pumping up water that can be routed through turbines later, would be even better but would also require a serious investment. But certainly from the provider's point of view, simply wasting it is better than selling at negative prices?

It will be 800 km in "extended cruise mode", meaning constant low speed, the way car manufacturers used to measure range before better standards were invented. In other words, they're cheating. Actual real world range will be about the same as a Tesla S 85.

Only just: a model S 60 is $69,900. And I imagine refilling with hydrogen at a gas station will cost a fair bit more than plugging in at home, making the Tesla cheaper and much easier to operate.

The S 60 has 2/3 the range of that concept FCV (208 miles vs. 300 according to Wikipedia), certainly way more than a fifth as stated in the article, and for $10,000 more you get an S 85 with a 265 mile range.

Actually, it goes about the same distance. When they say "5 times the range of an electric car", they are probably comparing with their own abysmal electric carts. According to Wikipedia, the Toyota FCV concept will actually have a range of 480 km (300 miles) which is pretty close to that of a Model S 85 (426 km according to the same Wikipedia article, assuming it uses the same method of range measurement).

And you can't fill it up in your own home, and a refill will cost more, etc...

Nope, I'm not getting one.

But as long as you keep more than 50% of the shares, you still have full control of the company, right? As long as you don't mislead the shareholders (which might lead to lawsuits) and make it clear from the start that this is a long term company which is just taking shareholders along for the ride without them having anything to say, what are the risks for SpaceX?

What I don't get is: who cares about hedge fund managers? Just do an IPO for the general public, small investors all over the world are more than eager to pour their money into SpaceX, they are literally asking him for it! Sure, it's a risky investment, and Elon's primary objective doesn't seem to be profit, but why say no to all that crazy excited volunteer funding? Unless he really has all the money he needs right now and wouldn't have any efficient use for more?

An optimist believes we live in the best world possible; a pessimist fears this is true.
