Comment Why worry about that? (Score 2) 258

You just left out most of the costs of fossil fuels!

Why worry about that?

When the DIRECT cost passes the crossovers, renewables first take up the new loads, then displace fossil fuels for old ones.

So you don't NEED government hacks to map the indirect costs into the market (and provide massive opportunities for graft and rent-seeking). The UN-hidden costs are enough to drive the market.

Comment THIS is how The Invisible Hand ... (Score 1, Insightful) 258

... by 2020 "all the renewable power generation technologies that are now in commercial use are expected to fall within the fossil fuel-fired cost range." [and will continue to drop below them] ... "Turning to renewables for new power generation is not simply an environmentally conscious decision, it is now -- overwhelmingly -- a smart economic one."

THIS is how The Invisible Hand eliminates greenhouse gas emissions. B-)

Cost of renewable energy collection drops as tech advances.
  * Solar photovoltaic, in particular, benefits from semiconductor tech.
  * Control and conversion IS semiconductor tech, with all the Moore's Law benefits.
  * Storage rides the battery advances driven by things like laptops and electric cars.
Cost of grid generation may benefit some from tech, but it's mostly mature and advances slower.

Meanwhile, cost of fossil fuels continues to climb as the easy stuff gets used up - while renewables (if you already occupy a good site) pretty much don't HAVE ongoing fuel costs.

As the cost passes crossover in progressively more locations, renewables will first take up new loads, then (as the second crossover is passed similarly and it becomes cheaper to switch than not), displace existing fossil fuel generation.

Just how many tabs are people keeping open at a time ...

I just checked: 725

that this is considered a good feature?

I do NOT consider it a good feature.

Things I WOULD consider good features:
  * Grouping tabs into multiple toolbrs by user-defined subject
          - With each separately switchable between visible and invisible
          - Stock, not an add-on / plug-in / whatever they're supporting this week.
  * Restoring the "delay image loading" configuration setting (for slow lines or expensive bandwidth)
          - And make the dropdown menu item to load a particular load-delayed image work correctly, rather than forcing me to "view image" to see what SHOULD be in the frame.

Comment Re:speculative execution of web content? (Score 1) 170

I only use AMD, so nothing's going wrong here.

There are (at least) two attacks based on speculative execution - and disclosed at the same time.

Meltdown is Intel-specific. Spectre runs just FINE on AMD - and some high-end ARM cores, too.

(It's beside the point in this case, though. Speculative loading and rendering/re-rendering/activating animations of a page when the mouse hovers over the tab will leak the same information regardless of whether the browser is running on Intel, AMD, ARM, or whatever.)

Comment No, you DON'T! (Score 1) 232

You need a mechanical physical switch with a switch guard.

No, you DON'T!

If you had such a switch, pushing it would have to be part of the test. Otherwise you've created a single point of failure that causes the live function to fail even though the test psses - and you don't find out until the missiles are inbound.

Yes, they should have done things like word and position the menu items differently, so hitting the wrong one by accident was less likely, and have glaringly different text and graphics (by selection, with the function still identical) for the confirm popups. But the further the test and live functions diverge, the more opportunity you have to build a system that passes the tests but doesn't work when you need it.

Conelrad (cold-war predecessor to the Emergency Broadcast System) had a similar failure: The test and inbound-nukes kickoff keys were paper tapes on adjacent pegs, and one day the low-ranking communications guy put the wrong one in the teletype tape reader on weekly test day, telling the whole country to duck and cover. Nothing new here.

(The teletypes had a bell and the newswires had a number-of-bings code for how urgent a message would be. I think major stories rated about a three. Max was ten, which was reserved for nuclear war warning activations. I recall one time in '65 or '66 when the AP wire tape got stuck on the bell code and that thing rang something over 30 times before they got it unstuck... Fun times.)

Comment Re:More than one dangerous fault here (Score 1) 353

What kind of thought train does from 'hang on there're some big faultlines here and we all know big ones are due' to 'sure here's a million bucks let me put all my stuff on top of this faultline'

So where can you build that DOESN'T have SOME recurrent set of disasters AND lets you make enough money to live well on?

East and south coasts have hurricanes (and much more often). Northern tier has blizzards. Sourthern states are lousy with tornadoes (and virtually any flat region south of mid-Michigan has some of them). Crippling / killing blizzards across the upper tier. Floods. Forest fires. Then there's a bunch of nasty diseases that are primarily local and break out intermittently. I could go on for pages.

Earthqakes can be bad. But big ones are rare - far rarer (even right on the major fault lines) than floods and tornadoes are in other parts of the country - and you can build structures that survive them just fine.

Even a 7ish like the famous Loma Prieta quake was, in the S.F. Peninsula, about like "15 seconds of mild turbulence" on a passenger airliner. That's nothing compared to, say, what a manufactured home goes through on its way from the factory to the site. Sure some old stuff in a couple spots failed - and the media zeroed in on them and made it look like several counties were flattened and burning. But they're really not as big a deal as their reputation suggests.

Comment Re:Not Soon Enough (Score 1) 353

Actually, California is due Real Soon Now (in human, not geologic, time) for a really big one on the Hayward fault (parallel to, and just across the bay from, the more famous, and more recently active, San Andreas).

I was looking at where it runs recently. It runs right under hospital row in Fremont - literally through the parking lot that separates my doctor's office building (and a surgery center) from the BART tracks. Right up the main driveway into the Kaiser medical complex.

Also, Interstate Commerce Clause.

There are plenty of laws that states pass that interfere with interstate commerce far more than local enforcement of net neutrality would. Many, if not most, businesses or individuals require state and local licenses in addition to any Federal Licenses they may need. Then they need to pay state and local taxes and comply with state and local regulations. In some instances you can't even sell stuff directly into a state unless you go through a local distributor. Thinking alcohol and cars, but probably other things.

The US considers itself a "single market" under US Federal regulations, but in many more ways it is not.

The cumulative effect of all those state and local regulations are barriers to interstate trade and commerce that amount to state and local protectionism.

Comment Only two for "Telephone" (Score 3, Interesting) 227

Back in German class in the early '70s, my instructor made this claim for "telephone":

In every other language in the world, it was called "telephone" - inheriting the sound from the American English word for the American invention and and (if necessary) distorting the pronunciation slightly to use the closest phonemes.

But German, with its standard of buildAWordByRunningTogetherADescriptivePhrase, called it a "fernsprecher" (far-speaker).

Women and girls constantly whine about guys bragging about their sexual conquests. Sharing nude selfies comes from the same mindset.

If the matriarchy is truly to arrive, women have to stop being so stupid.

Nothing about this seems to warrant blaming the victim.

I'd blame you if your car was stolen and you left the door unlocked and the keys in the car.

The thief should still be arrested, and I'd be glad he (because, honestly, how many female car thieves are there?) was, yet I'd still blame you for gross stupidity.
