The very low end cars in the linked story really don't look that interesting, but there are other recent Chinese electric cars that look more promising: http://www.carnewschina.com/2015/12/06/the-jac-iev5

Idiocy such as this is a strong argument for the use of PAKE rather than CA-based authentication. No need to trust anyone other than the site you're trying to connect to: https://en.wikipedia.org/wiki/Password-aut

An interesting article, and clearly it's right that wind and solar (at least in Europe) need backup from other sources that can be spun up for a few days when it's not windy across the continent. Now, if we factored in hydro (not

Seems like these Sodium batteries would be well-suited to grid load-shifting, rather than anything mobile. They're likely to be cheaper than lithium batteries and cope with more charge cycles, but heavier. Pretty much exactly what yo

I switched my desktops and laptop from FreeBSD to OS X around 10 years ago, while running FreeBSD and Linux for my servers. The main reason was the "it just works" nature of OS X on the laptop. Too much hassle getting sound and W

For me, the best thing about this is not the price. It's the combination of small form factor and no Ethernet/USB hub. With the original Pi, almost half the power consumption came from the USB hub/Ethernet controller chip -

Or equally, Pl_3 (3 atoms of Plutonium) would be very hard to distinguish from PI_3 (Phosphorus Triiodide), especially in a sans-serif font. Pu seems like a good call to me. If it also amuses 4-year olds, then so much the better.

Once they start to recover the first stage, they'll get a lot more information about how their systems really performed, as opposed to how they think they performed from the telemetry. You can do all sorts of testing on all the return

I didn't say not to bother; I just said the protection provided by ASLR is weaker, even on 64-bit systems, than most of us believed a couple of years ago.

I'm not sure I'd place much faith in ASLR these days. Bittau's Blind Return Oriented Programming (BROP) http://www.scs.stanford.edu/brop/ makes that only a speedbump, not a real obstacle, for any server

The analogy is a bit strained. It's not really the Internet that's harmful, but rather some subset of the humans attached to it. We could cure some of that problem by mandating the abandonment of all online anonymity, but that c

El Capitan won't let you create the path in one go (it gives file name too long), but you can create it incrementally: sh-3.2# pwd /private/var/root/1.../2.../3.../4... sh-3.2# ln -s /var

If we can't get privacy using crypto, we could always use chaffing to make their database useless. We just need a list of sensitive websites that want to hide their true users, and an ad-serving network that randomly serves up links t

A self-driving car will have better reactions, but it's still governed by the laws of physics. Beyond a certain point, all the self-driving car can do is minimize the collision speed. After that, you can be sure the cameras on the se

Yes, but why is a high bypass turbofan quieter? If I understood correctly, it's because most of the thrust comes from the large slow moving fan, so you don't need to blast nearly so much air through the turbine as a turbojet to g

by mhandley 11y ago
I wonder if instead of gearing a single large fan, you could just remove the fan from the turbine altogether, add a much larger alternator, and power several large electric external fans from each turbine? That would give you more fan area

The tube already does regenerative braking. This trial is about better regenerative braking. Currently, the trains return power to the track when braking, but if the track is already at capacity the remainder is dumped via resistors on-boa

The electric motor is around 90% efficient, but the thermal efficiency of a jet engine is (if I recall correctly) only around 30%. So the batteries only need to contain 1/3 of the energy of the jet fuel. Batteries are still a long wa
