The carbon in the fuel comes from CO2 which is captured out of sea water. The problem with fossil fuels is that they transfer old carbon which used to be stored underground into the atmosphere. This process only uses carbon that is already

Github has some nice features that chromium.googlesource.com lacks, like being able to list all of the commits that have changed files in a specific sub directory. Synchronising a mirror automatically is pretty trivial so I imagine they&#x2

I'd like to see strong evidence too. Where I live there have been a far larger number of pedestrians seriously injured by cars than cyclists - but you're right far more time is spent walking.
127.
by xxgreg 12y ago
Ok that leaves pedestrians, who have twice as many head injury's per km. Most likely due to being hit by cars - perhaps cars should have airbags on the outside too...

He also cites an Australian study, which concludes risk of head injury per million hours travelled: Cyclist 0.41, Pedestrian 0.80, Motor vehicle occupant 0.46, Motorcyclist 7.66. So if you want to be consistent you should update your commen

Does this mean you will now wear a helmet while driving, because it gives you 85-88% less chance of serious brain injury?

I think the title is wrong - it should be: "Why it makes sense to drive wearing a helmet" Based on: We can also approach it from the perspective of injuries per million hours from a 1996 Australian study looking at head injury ris

Very cool. However inverters are DC->AC. I think the correct term for AC->DC converter like Dart is a "rectifier".

It's called pumped storage. It exists, but only at larger scales than a household system. It's ~80 efficient. http://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity

"get the maximum energy during the year." There are already countries where the cost of electricity from PV is below the cost of electricity bought from the grid. In these countries every Watt you generate yourself saves you money

To be fair the Tesla is aiming for a Model E range of ~200 miles, vs ~100 for the i3. So getting double the miles for the same price is a good deal. (Though the i3 does have an ICE range extender option which gives it ~200 miles too)

I remember using one of those mid nineties - I think is was a Sun workstation. It had a metallic mouse pad with a grid pattern etched into it.

It works. There are a few people using it server side. There is a Heroku build pack. The HTTP server is a bit slow, sounds like this is being addressed, and shouldn't be a limiting factor. I wrote a postgresql driver, which works ok. M

The best bit about Dart is not new features, but many of the footguns that have been removed compared to JS. Note: Dart doesn't have generators, and Ecmascript is not planning on adding optional types.

by xxgreg 13y ago
One big advantage of top-level declarations is it is possible for the VM to use a snapshot for fast start up. This is not really possible if you must interpret top level code to build up your top-level declarations, as done in JS. Using sna

Yes - benchmarks need to be ported very carefully to make sure they measure something meaningful. What makes you think that there are problems with this port? It is an old well used benchmark, used for benchmarking object-oriented code with

by xxgreg 13y ago
Sure, take all benchmarks with a grain of salt. However it's worth noting that deltablue has been used to benchmark polymorphism in Smalltalk, Self, the JVM, and V8. Some of Nickolay's numbers are from a version of the code written at Sun l

Yes - It's difficult to describe the difference in one sentence ;) I agree that there are many shades of the rainbow between a JIT and an interpreter. "V8 compiles JavaScript source code directly into machine code when it is first executed.

"Dart is purely object oriented" Languages such as Java and C# have a distinction between objects and primitives such as int and bool. In Dart all types are objects - even null! This is why Dart is pureOO. Dart has some of the classic highe

by xxgreg 13y ago
Dart can run in production mode where type annotations have no effect, or in checked checked mode where they will trigger a runtime error (i.e. behave like an assert). So you're both right ;)

Yeah - it would be nice if dart2js supported externs as in the closure compiler. I imagine that will happen at some stage.
