Comment Re:Too bad it wasn't SciPy (Score 1) 84

I jumped from Matlab to Scipy/Numpy, skipped Octave, but I'm so happy with Scipy/Numpy that I wouldn't consider using Octave.

From a purely numerics point of view, I'm sure Octave has all the features that Scipy/Numpy has. Most of the benefits of Scipy/Numpy come from the Python programming language itself, which I have to assume is much more developed than Octave's language. Being able to write GUIs for your scientific apps using tkinter (or some other library) or reading/writing to excel formats directly or wrapping your code up using pyexe for distribution or interfacing your python code with the web or a database is just the start of the Python advantages (after a quick search I see that Octave can do some of these things, but I'm sure Octave doesn't have all the libraries that Python has).

IMHO, if scipy/numpy ever get working with PyPy, then this would truly be amazing.

Comment Re:forced? (Score 1) 811

TFA didn't suggest that she was forced.It said she took the advice of the TSA worker over the advice of her doctor. The doctor's note said to avoid the body scanner, she asked the TSA worker if it was ok, and the TSA worker said yes. IMHO, a doctor has more credibility over a TSA worker in this case, I'm not sure why she didn't think so.

I agree. I don't know anybody who uses a computer and doesn't rely on Microsoft Office. And crossover office is not good enough (it might work well enough, but it's not easy enough for my parents to install themselves).

It comes down to the fact that distros like Ubuntu are still too difficult to use for normal folks. Give your parents Ubuntu and see how far they get trying to play a DVD or uploading music to an ipod.

"NHTSA in fact drains the gas tanks on gas cars (including the Volt!) BEFORE they wreck them because of the danger of the gasoline."

Do you have a reference for this? Not that I don't believe you, but if this is true, GM just got a whole load of bad press which may have set back the electric car over something that was NHTSA's fault. It's unbelievable that they wouldn't test gasoline cars and electric cars on the same footing. If they first drain the gas tank then they HAVE to drain the battery before the test for a good comparison.

Comment Re:Traditional journals already do this. (Score 3, Insightful) 57

I think the tweet idea is slightly different. For example, a lot of work that a scientist does is collecting data to make sure equipment is working properly. Usually these experiments aren't worth publishing and probably wouldn't make it past a peer review because 1) they're usually not novel experiments 2) they don't tell a story or add much value, but I think it could be useful to share this type of data. I mean, if you've collected it, why not share it?

My smartphone changed my life (I think for the better). It's the GPS, not the web browsing that is the best feature. Last week I went on a business trip, rented a car, didn't have to bother with maps or worry about getting lost, my phone told me where to go.

This is getting blown way out of proportion.

See this article for another view: http://www.economist.com/node/21541395

Specifically the last paragraph:
"What is left unsaid in all this is the fact that conventional cars with a tank full of petrol are far greater fire hazards than electric cars will ever be. Some 185,000 vehicles catch fire in America each year, with no fewer than 285 people dying as a consequence. But, then, people have been living with the hazard of petrol for over a century. Irrationally, electric-vehicle fires are perceived as somehow more worrisome simply because they are new."

Comment Re:For one battery that goes, billions are just fi (Score 1) 277

It would be nice to know if the phone was ever dropped, or its battery replaced at any point, or if a non-standard charger was used.

In this case, the backplate of the iphone had been replaced (you can tell from the apple logo in the picture). Obviously I don't know if this was the cause though, but perhaps the backplate was replaced because the original broke during a fall which may have jolted some internal circuitry close to the battery causing a local hotspot near the battery and then thermal runaway. Somehow I doubt that the battery would have been punctured just by dropping/replacing the backplate though.

Comment Why all the hate for these patents? (Score 2) 323

After reading multiple posts and comments about Apple's patents, there are a lot of people who feel this is counter productive...I don't know why.

IMHO, the patent system is broken when a company can file a patent without actually having a solid working product first, this sometimes happens. But clearly, in a lot of Apple's patents, such as this one, it isn't the case. If Apple, or another company, invests billions of dollars into R&D to make a product, they should be able to protect it. In fact, it would be counter productive if they couldn't protect it because it would discourage them from investing in R&D and then the nice things wouldn't even be invented in the first place.

but you're ok with lithium-ion batteries exploding if short-circuited or heated to above 120C, mm?

I'm just saying be realistic and stop making it sound as if lithium-ion batteries are intrinsically dangerous so that you can push your agenda for your design

A lithium-ion battery will not normally reach 120C. It will only do so if damaged or if there's a defect. Just like you don't want to be driving around in a car with a damaged gas tank. You're in just as much danger sitting on top of a tank of gasoline as you are sitting on top of a lithium-ion battery pack.

Lithium-ion batteries are not any more intrinsically dangerous than other high energy content materials. Whenever you concentrate high energy things, they must be treated with respect. Just because you have to take different precautions when working with lithium-ion batteries as opposed to gasoline, does NOT mean lithium-ion batteries are more dangerous.

you _can't_ put a material that spontaneously catches fire when exposed to air and water (lithium) into a car!

You realize that you're talking about lithium-metal right? All mainstream electric vehicles are using lithium-ion which is a different technology. A lithium-ion battery _will_not_ catch fire when exposed to air and water. Lithium-ion batteries will catch fire when heated to above around 120C which can happen by an internal short circuit, or if punctured by a piece of metal.

Stop spreading FUD. Lithium-ion batteries are much safer than lithium-metal batteries, which is why lithium-ion batteries are being used despite their lower energy density.
