Sulfur Polymers Could Enable Long-Lasting, High-Capacity Batteries

imsabbel mAh is only half the equation (131 comments)

What matters, in the end, is the amount of energy a battery can store.

With Lithium Sulfur cells, the voltage is a little more than half as high as for Lithium Ion batteries, so the initial advantage is not as large as it might seem from the mAh numbers.

Will Peggy the Programmer Be the New Rosie the Riveter?

imsabbel Re:Programming is over-hyped as a career (333 comments)

Also, didn't Rosie the Riveter quite after a couple weeks because the job was too dirty and dangerous?

Seems like a bad goal to set...

Rolls Royce Developing Drone Cargo Ships

imsabbel Re:What do the humans actually do on a ship? (216 comments)

Oh, yeah, you COULD do it.
If you overengineered the ships (making them 5 times more expensive) AND had complete checks agter every 1000 operation hours of everything (which is basically every round-trip for a container ship).

Tesla Model S Can Hit (At Least) 132 MPH On the Autobahn

imsabbel Re:Impressive. (410 comments)

Wrong. Per default, Autobahn has not speed limits.

Unless indicated otherwise, if you enter the autobahn, NO LIMIT.

Yes, there are speed limits quite commonly, but if you discount Stadtautobahn stuff and the Ruhrpott, 2/3rds of it are unlimited. Case in point: You can drive Stuttgart/Berlin and have all but 50km or so of the distance unlimited.

6TB Helium-Filled Hard Drives Take Flight

imsabbel Re:Great... (297 comments)

In theory. In practice, helium will interact with, for example, iron alloys (steel), ending up with de-electonized protons migrating through the bulk metal, and at the other end snatching up some of the fermi-gas and going their merry way.

The same way, in vacuum systems, getting rid out of the stupid hydrogen magically appearing out of nice stainless steel enclosures that have been ultrasonic cleaned and baked under vacuum is a real problem. I have seen suggestions of burning the whole chambers under vacuum at 650C to get the protons out, and even that isn't really the end of things.

Smartphone Sales: Apple Squeezed, Blackberry Squashed, Android 81.3%

imsabbel Re:Expensive Apple (390 comments)

How the hell do you get a 15k phone bill?

And why are you bragging about your stupidity to not get a contract to accomdate your usage profile?

Firefox's Blocked-By-Default Java Isn't Going Down Well

imsabbel Re:Uses of Java applets (362 comments)

Are you posting in Bizarro land?

Your own link tells us that over 91% of the users of chrome didn't even encounter a SINGLE java applet in a whole MONTH.

Thats an absolutely overwhelming sign that java is almost extinction-level rare in the web. Hell, I would bet that the rate of people encountering embedded MIDI files was much higher.

Boeing Turning Old F-16s Into Unmanned Drones

imsabbel Re:Sacrilege (239 comments)

The F16 was always the bargain bin little sister of the F15 (the "real" fighter jet).

Its main appeal was that it was _cheap_, not that it was good.

Why Is Microsoft Setting More Money On Fire With Surface 2?

Obviously that comment IS needed and insightful, seeing all the mouth breathers who cannot tell about the RT from the Pro.

Why Is Microsoft Setting More Money On Fire With Surface 2?

imsabbel Re:Not being well reviewed ... (616 comments)

People cry about 900g being heavy, but try to find a laptop of that size thats even remotely as capable. Even the smallert Macbook air is heavier, and its inferior in every single way.

Plus the docking station with 4k capable video out should take care about it anyway.

Why Is Microsoft Setting More Money On Fire With Surface 2?

imsabbel Re:Ah slashdot bias.. (616 comments)

Ah, right. Because nobody cares about an order of magnitude speed difference.
Because all those nice, docile consumers in their walled google/apple gardens don't need to MAKE anything, and media decoding is done in hardware codecs.

US Mounted 231 Offensive Cyber-operations In 2011, Runs Worldwide Botnet

imsabbel Re:Conspiracy theory: Bitcoin crash of April 2013 (367 comments)

If the US wanted bitcoin gone, they could have done so.

There exists something called an "51% attack", which means that anybody having more than half the hashrate of the Network is acknowledged as the boss and can do as he wants (stuff like spending the same bitcoin multiple times, manipulate the difficulty of future block mining, etc).

Back in April, before mass ASICS, the US could have trivially gotten that far. Hell, last year anybody willing to spend 5-10 million could have done it with off-the-counter hardware.

For an agencies who have a double digit BILLION black budgets, this is totally peanuts.

U.S. Gov't Still Fighting the Man Behind Buckyballs; Guess Who's Winning?

imsabbel Re:Those magnets sure were fun (555 comments)

I don't think its disturbing to be able to buy them "so easily".

I mean, seriously. You need a credit card or paypal to buy from them, so you are no infant in the "I eat metal stuff" phase.

And secondly, you have dozens of way more deadly things in your appartment at any time, anyway.

U.S. Gov't Still Fighting the Man Behind Buckyballs; Guess Who's Winning?

imsabbel Re:Those magnets sure were fun (555 comments)

DX made a new site just for their lasers. I think the name is yourlaser.com or something.

IIRC, they did this because custom troubles for the main DX stuff,even if their were no lasers, got out of hand, in particular in australia.

Cold War Plan Tried To Put a Copper Ring Around the Earth

imsabbel Re:Sooo.... (184 comments)

No, it did NOT work as planned. Because those dipoles were supposed to de-orbit after a few months.

Instead, a significant part is STILL up there.

BMW Debuts First Electric Vehicle Made Primarily of Carbon Fiber

imsabbel Re:20 min of fun (164 comments)

You might not realize it, but I would bet a lot of money that 90% of the time, you are using less than 20% of the power your car has.

Seriously. If you have a 200HP car, it will do that if you floor the pedal a bit below the redline. Normal driving? It takes maybe 15-20HP to keep a car moving at 70MPH on the highway.

Yahoo Receives Special Recognition For Fighting For User Data Privacy

imsabbel Ain't it nice (58 comments)

This is just like Kafkas "Der Prozess".

You got secret laws that people/companies are ordered by a secret court to be followed, and they are not even allowed to tell anybody about it.

Land of the free.

I remember back when a CD-R cost >$20, and there was still >95% success rate.
