Comment Three headed outlets and two surge protectors. (Score 1) 136

It sounds like you are traveling with only passive adapters, and so you would need to protect each and every device separately.

So own two single-outlet surge protectors, for they are quite small and as mentioned elsewhere they must be voltage-specific and make your chain thus:

PassivePlugAdapter:SingleOutletSurge:ThreeHeadedOutlet(s):Appliances

This will pack quite compactly, as the N Passive Plug Adapters get replaced with N/3 Three Headed Outlets

Comment Re:Solar Roadway Bull$it (Score 1) 405

Dave's argument starts with real-world numbers regarding solar insolation and PV conversion efficiency to establish a baseline. The exact details of a specific implementation won't change the broad conclusion that the energy balance alone, even if you take out the gee-whiz features of the Solar Freakin' Roadways design such as LEDs and networking, doesn't make sense.

When you add all the other stuff on top, it only gets worse.

Fundamental issues: Only so much sun hits the earth, and PV cells only convert a certain fraction to usable energy. When you mount them flat on the ground, you reduce their efficiency further because they're not perpendicular to the incoming light. When you put them under thick enough glass to support real physical loads such as cars and trucks, you lose even more. And when you distribute them over a large area, transmission losses become a Big Deal.

I'm personally skeptical you could build solar panels that would withstand actual vehicle traffic, at least the way we build roads here in the US. Real world roads aren't flat, and they change shape over time as they wear and as the road bed settles and degrades. But real world glass isn't very plastic, and won't conform to a changing surface. It's more likely to crack and break into many pieces. Likewise for the PV cells under it. You'd have to put some beefy steel plates under these to guarantee a sufficiently flat mounting surface to support the load-bearing glass.

Mobileye is collision avoidance and Tesla is enhanced lane following.

Which is why I believe Tesla is claiming coast-to-coast driving.

Autonomous vehicles going from A to B on the well marked, (mostly) pedestrian free interstate highway system is relatively easy. And with Tesla charging stations at some rest stops all one needs to do is add a few mapped "delivery lots" at popular exits and one has created a first-grade autonomous vehicle route.

Two standard units a day should not cause a lasting mental fog for any adult over ~100lbs.

Unless someone is consuming said alcohol via a method bypassing the stomach it is possible, but extremely difficult to get legally drunk with two drinks. For the liver sees it first, and absorption rates aren't instant, so there should never be a period with one excess ounce of alcohol in the blood stream.

If an adult feels anything two hours after two standard drinks they probably should have their liver function checked.

Comment Doesn't this just affect Chrome? (Score 1) 136

Seems like this should just affect Chrome / Chromium and anything derived from those, as it's an implementation issue in the V8 JavaScript interpreter. (V8 is the name for the engine in Chrome.)

That is, it's not a JavaScript / ECMAScript bug in the standard (as implied by the headline), but rather a bug in one company's implementation.

Compare/contrast with the comically bad PRNG enshrined in the C standard itself:

static unsigned long int next = 1;
int rand(void) // RAND_MAX assumed to be 32767
{
next = next * 1103515245 + 12345;
return (unsigned int)(next/65536) % 32768;
}

Thankfully, though, this is just an example, and not required by the standard. But, many simple C compilers use that implementation. It's got plenty of problems, such as always alternating between even and odd values. If the last value was odd, the next value is even....

I'm still using v2.81, it does exactly all it needs to do.

What I came here to say. 2.81 was everything I wanted out of a media player. 3.x was crap, everyone agrees upon that. 5.xx was an attempt to be 2+3, and it did fix most the glaring issues with 3, but was never compelling to much of anyone as end-game 2.x had already sealed the deal.
