The issue is settled, mankind's massive emissions affect mankind's environment, Earth.
a: If it's "settled", it's not science.
The only question now is what the fuck are we going to do about it, and who can we trust not to line their pocket on both sides of that line?
"Only" question? There are a HELL of a lot of steps between "mankind's activity affects the planet's temperature" and "It's a disaster that must immediately be fixed by crippling the economy and instituting totalitarian control on human activity by governments".
Wait - we still have an antitrust agency? I haven't heard much from it during the past few decades.
The entire FTC's budget for 2016 was only about $307 million. They only asked for $342 million for 2017.
If they're going to be given more responsibility and actually exercise it effectively (which involves bringing, and winning or settling, suits against multibillion dollar conglomerates) I expect they'll need some more.
That wasn't what the media reports said. What it said was that he wants to limit the FCC to spectrum control, and move the other functions to the FTC.
I've been advocating that for years - at least for the "Network Neutrality" issue.
The problems that network neutrality is trying to address are mainly anticompetitive behavior and consumer fraud, where ISPs selectively degrade service either to extort additional fees or limit users who make heavy use of their contracted bandwidth (consumer fraud - giving less than what was advertised or what "internet service" commonly means) or give a competitive advantage to their own "value added" or "content provision" services, those of other divisions of a media conglomerate, or of partners, (anticompetitive "tying", vertical integration, and cartel formation).
As the major federal-level consumer protection agency, charged with enforcing consumer fraud and antitrust law, the FTC is well qualified to handle this sort of thing. It also has a track record of doing so. Their antitrust actions, for instance, include the historic breakups of Standard Oil and AT&T, the opening of IBM's eased mainframe computers to peripheral built by other manufacturers, and the Windows Browser tie-in suit decision against Microsoft.
Among the things you might see from a move of such regulation from FCC to FTC might be media conglomerates forced to divest themselves of ISPs, ISPs forbidden to sell preferential fast-lane service, and bans on cuting off or degrading the service of heavy users.
After the way he was treated by the mainstream media - owned by these same conglomerates - I'd expect Trump's administration to be more than happy to penalize them by breaking up these conglomerates.
- We get more network neutrality - by separating the ISPs from the media conglomerates that incentivize NON-neutrality.
- The Trump administration gets to spank the media conglomerates that were completely in bed with the Democrats during the election - in the name (and actuality!) of consumer protection.
That's either a typo or the Ukraine has a VERY wimpy power grid, to have a "substation" that small.
330 kW is 440 HP, in the moderate-low range for a big rig's semitractor engine. In the US a typical household averages over a kilowatt 24/7, with peak hours higher. So a "substation" that small would serve a neighborhood of maybe a hundred houses or a bit more.
In my Silicon Valley townhouse's neighborhood, built back in the '50s or so, we have over a hundred houses served by a single-phase "bank" - a parallel connection of three "pole pigs" spread out around the neighborhood, with their primaries and secondaries tied. It doesn't even rate an independent switch. (When a goose shorted and dropped a primary line they just disconnected the primaries to the segment containing the bank until it was fixed.) Several banks on each phase are tied together before you have enough load to rate actually installing a switch on the feed, several of those before it rates a remote-controlled switch, and several small towns (or a substantial factory) before it rates a "substation" - a fenced-off chunk of land with big box equipment.
Actual experience of my wife with H1-B employees (including the "chagrined when discovering the forged credentials" case).
When getting your H1-B you need to provide documentation from your university as proof of your degree. The university must be on a list recognized by the US government. They validate the information with the university rather than just rubberstamping it.
Any of the following would explain that:
- The agency faked the references, too.
- The government didn't do the validation you claim it does in every case.
- The government doesn't do the validation you claim and you're talking through your hat.
Please put your flamage aside for the moment and give us a reference to documentation showing that the government officials actually check credentials, rather than doing spot-checks or taking the applicant's word for them (or bribes).
Meanwhile Win 3.11... Is still running fine on test equipment. The manufacturer says do not upgrade to any other version of Windows.
I have a gang-programming-and-testing production tool from one of the top three (or so) manufacturers of BLE systems-on-a-chip. Our startup needs this (or a suitable alternative) to go into volume production of our initial products.
It comes with an application - in source in a build environment. This allows it to be customized, to add tests for the peripherals added to make the final assembly, and to integrate into production processes and databases.
But the build environment is only supported in Windows 7, 7 Pro, 8, and 8.1, using Visual Studio 2012. The executables and DLLs produced run only on those or XP.
The executable/DLLs use.NET, too, and the way they use it breaks the GUI under wine, even with genuine Microsoft.NET installed. They run correctly, but the status display is corrupted in a way that makes it unusable. So at the production site it needs to run on genuine Windows at one of those levels. B-b
As of the last time I checked (a couple months ago), the manufacturer is unwilling to port to another OS or version - even though all of them (except maybe 7 Pro) have been end-of-lifed by Microsoft.
I would restrict H-1Bs to only areas of the country where residential rents (per sq. foot) are in the lower 50 percentile.
So you'd give all the jobs-for-locals benefits to residents of a few big cities and leave the rest of the population in competition for high-value jobs with underpriced H1-Bs?
Looks to me like you completely missed the point of the Trump Win. He was elected by exactly those people you propose to leave out in the jobless cold, over a set of issues of which loss of jobs to foreigners by H1-B visas, illegal immigration, and outsourcing topped the list.
This election - not just the Presidential, but all down the ticket - was largely a revolt by the rural and the downtrodden against the urban elites. Trying to fix the problem only for those living in pricey cities and leave it in full force for these voters is a recipe for more extreme shakeups.
If the soapbox and the ballot box both don't work, and the jury box is unavailable, the only one they've go left is the ammo box.
... do a skill assessment of their foreign contractors. The number that turn out to be "exceptional talents" with hard to find degrees or special training/experience is actually rather small.
And the number who ACTUALLY HAVE the hard to find degrees is even smaller. The middlemen who bring in the H1-Bs sometimes pad their resumes with non-existent credentials in order to get the necessary approvals from the government (or the employer to do the hire). often to the chagrin of the employee in question shoud he or she eventually find out about it.
... there's no relation to the book [Brave New World] 's subject matter so why allude to it?
"Brave New World" is an idiom (for historical periods that are more utopian than the periods preceding them) that predates Huxley's famous book (which put an ironic and dystopian twist on it).
The sentence uses the pre-Huxley meaning of the idiom and doesn't make a visible reference to the book (though such a reference, and the dystopian newspeak twist, is unavoidable). To be grammatical it requres the article, thus the "[sic]".
... the issue is you can't compare the stored energy in gas... with a 150A at 2000V power supply... If you spill a bit of gas as long as nothing is actively burning you just walk away and get something to clean it up,...
But if it happens to ignite you can find yourself dancing in a heat source that exceeds the 22 megawatt level. For a short time, anyhow. B-b
If you are grounded and put 150 amps into your arm you could have some serious issues.
If you put 10 miliamps (i.e. one one-hundredth of ONE amp) up your left arm, or 30 ma between two contact points on your chest, or even a few microamps directly into the blood or inner tissues, you could have some serious issues as well. Like ventricular fibrilation. If there isn't a defibrilator handy right away, you're gone.
Available currents above that level are meaningless - all that matters is that the necessary tiny bit of current is delivered (while a larger current, big enough to cause the whole heart to contract simultaneously, is not). High voltage is an issue, but only because it is more capable of breaking down the insulating layers of the skin to drive the necessary current into a path that includes the heart.
Which is why I described a system that would keep the output power off until the exposed terminals are safely embedded in the car's receptacle, and shut down and crowbar the power supply output of the "pump" in time to protect a human body from electroshock if the insulation fails. Sort of the 300 kilowatt DC equivalent of a GFCI outlet, or a "bus differential" breaker control in an electrical substation (which actually has a chance of saving a lineman who accidentally hits a bus conductor with a metal ladder).
If you're not talking about direct contact between a body and the electrical supply, you're down two two other mechanisms: Arc flash and heating from wiring faults.
Heating from wiring faults is very comparable to heating from flame, and the relative power levels of the two sources is an apt comparison. In this case the higher power of the gasoline case, plus its ability to accumulate and burn at a rate only loosely related to the pumping rate, makes it far more of an issue than an electrical fault (which would also, no doubt, be quenched in milliseconds).
Arc flash does damage by light - ultraviolet, visible, and infrared, largely through heating - and by impact from vaporized material. This is comparable to the infrared from a flame and the flash and impact of debris from an explosive ignition. Again the relative available energy is germane to comparing the damage potential from the mechanisms.
If there is not written evidence for all of these then their document retention policies are "well tuned" albeit since they must be ISO9xxx certified they must have something left in the decision chain.
ISO9xxx isn't about documenting a decision chain.
ISO9xxx is about insuring that the company can build the same thing repeatedly, despite things like personnel with critical knowledge leaving the company or dying, and being replaced by ignorant newbies.
ISO9xxx is perfectly happy if the instructions for a step of building widget X are written on a designated whiteboard in a designated cubicle, or sitting in a basket on top of a designated file cabinet, as long as this is documented properly so it can be rediscovered the next time they need to do a run of widget X.
... the first thing I always want to see in regards to car battery technology is how many charge/discharge cycles can it handle?
That's the wrong metric for lithium ion batteries.
As I understand it, the main ageing mechanism that kills them is oxidation of the graphite anode, which starts when the cell is manufactured and isn't appreciably affected by usage except for being accelerated somewhat by being stored at high temperatures with low (20%) charge.
Charge/discharge cycling does cause some "wear", but it's generally a smaller effect. (That's why the advice for, for instance, laptop batteries is not to avoid using them. For long term storage unused they last the longest if put away at about 40% charge.)
This means that it's mainly the age of the cells, not their usage or charge history, that determines when they die. A pack designed for 7 years life will probably give you 7 years life unless you either run it nearly all the way down (which the battery management logic should prevent) or run it down to a low charge and leave it out in the sun for months.
Also: At least one new anode material appears not to age measurably at all.
You can't charge them below 0C. So you'd need a heated garage.
Or a heater in the battery pack to preheat them up to 0C before the main charging begins. Once they're charging, the slight inefficiency of even the best ultrafast-charge cells makes the problem keeping them cool, rather than keeping them warm enough. (Ditto when they're discharging, of course.)
If you are going to supply them with, say, 300 kilowatts or so for 20 minutes while charging them, you can spare a kilowatt for a few minutes to drive a heater (just as you supply a block heater with 400 to 1500 watts, the whole time a car is parked in such below-antifreeze weather, to keep a water-cooled engine from freezing hard enough to blow out the freeze plugs and/or make starting possible.)
I think he's referring to the phenomenon where, in very low temperatures, the tires lose flexibility. So if you park and let the tires cool, the flat spots that were against the road surface stay flat until the car has moved far enough to heat the tires a bit.
Ka-bump, ka-bump, ka-bump, like driving on square tires (though only one side, not four, is actually flat).
Charging that in 20 minutes will be around 300Kw, 300V and 1000A or 1000V at 300A or some variation thereof. Any way you look at it the cable and connectors will be ridiculous.
Hardly.
Take 2000V 150A, for instance. 1/0 or 2/0 welding cable, insulated to that voltage, would be well within the current electrical code. The stiffness of such a two-wire bundle would compare favorably to a gas-pump hose - especially in states (like CA) where the hose includes a vapor recovery passage.
Most wiring these days is insulated to 600V by default because it's hard to make insulation any thinner without making it fragile. 2000V is not difficult at all.
You could even include a coaxial "shield" that would detect any failures in the inner cable's insulation, along with signal-level switch wiring that would detect whether the plug was fully inserted into a matching connector, to prevent the enabling of significant current unless the system is safe.
A gasoline pump, running at 10 GPM, is feeding your car about 22 megawatts of fuel heat-equivalent. What's such a big deal about feeding it a mere 300 kilowatts, nearly 2 orders of magnitude less, as electricity rather than liquid fuel?
Is there some reason you can't be bothered to write down the ruleset if you think you wouldn't remember it?
You're kidding, right? Writing down the rule set would be writing down ALL of my passwords, past, present, and future. B-b
But my point was that:
- The variability of "password quality" rules means the ruelset has to be complex enough to handle different cases for sites with different rulesets.
- The lack of display of the site's password quality rules at login means a password generation ruleset isn't enough. You still need to record something about the particular site to know which workaround branch of the ruleset to use with the site.
I migrated my home environment from Solaris to Red Hat Linux for the Y2K boundary. Not too long after that, Red Hat dumped consumer support (handing it off to Fedora) to concentrate on Enterprise. Oops!
I'd have been happy to stick with Red Hat if they'd stuck with me.
I was a vocal opponent until i had to actually use and rely on it. I wouldn't go back if you paid me. It has made my job a lot easier.
How nice for you. What a pity your experience and mine are not the same.
We're seeing a.lot of flamage about the lack of security on IoT devices. One company I work with is making such a thing. The presence of systemd increases the expected scope of a security audit to the point that they expect to migrate the production version to another OS rather than absorb systemd by upgrading to the current version of the linux distribution they used for initial development.
On problem with systems is the wide variety of disallowed / allowed / required characters in passwords for various sites ("minimum of eight characters, at least one lower case, one uppper case, and one digit (but we won't accept puncuation marks and don't say that)"), in rulesets that are only displayed when you set the password, not when you enter it.
A language is thriving or dying by the number of inexperienced developper trying to learn it. If no inexperienced cev learn it... it is dying.
But your thesis ("[web searches for help on a language is] actually a good metric [for language viability]") doesn't follow from that assumption.
Other possible explanations include:
"The C language is easy enough to understand, compared to others such as java, that references to documentation and searches for arcane knowledge about it, even by noobies, are rarer."
"The ordinary documentation of C is clear enough that web searches are rarely needed."
and so on.
This doesn't mean that C use ISN'T declining. But it does mean that additional measures using different metrics would be required to determine that this result isn't just an artifact of the methodology.
If generalized beyond patent trolling suits it could severely limit the ability of shallow-pocket plaintiffs to obtain legal council on a contingency fee basis to obtain redress for the torts that damaged, and perhaps impoverished, them.
The result would be that the legal system becomes accessible only to the rich.
Most of the high level stuff will have decayed significantly by then. Send workers in, chop up what's left,
Fine so far.
seal it up in drums and throw it in an abandoned salt mine.
Definitely not a salt mine. The US used to consider that (or salt domes). Then they figured something out:
The heat (and even a little builds up) causes water to migrate through the salt to the heat source. Then you've got hot stuff sitting in saturated salt solution. This has lots of opportunity for exciting failure mechanisms.
Once the stuff is out of containment, the water-soluble part has the opportunity to spread through the whole salt deposit, which might be very large (such as the remnant of an ancient inland sea that dried up). Note that small amounts of chemicals dumped in salt mines under Midland Michigan showed up in the salt mines under Detroit.
Once the high-level stuff has decayed enough that the stuff is reasonably safe to handle, it's potentially very valuable, and might be made into useful artifacts in as safe a manner as tech in the 2100s can manage. For instance, this was a graphite moderated reactor, so there's a BUNCH of carbon 14 in there. It could be made into things like the diamond-based nuclear batteries (low power, safe to handle, with lifetimes longer than human civilization so far) that were discussed here last month.
In another hundred years or so who knows what the technology will be capable of? You can predict that it will be a LOT better. But you can't predict exactly what it will BE. (If you could, you could do that stuff NOW rather than waiting for the breakthroughs. B-) )

Is there some reason you can't be bothered to write down the ruleset if you think you wouldn't remember it?
You're kidding, right? Writing down the rule set would be writing down ALL of my passwords, past, present, and future. B-b
But my point was that:
- The variability of "password quality" rules means the ruelset has to be complex enough to handle different cases for sites with different rulesets.
- The lack of display of the site's password quality rules at login means a password generation ruleset isn't enough. You still need to record something about the particular site to know which workaround branch of the ruleset to use with the site.
Second that.
I migrated my home environment from Solaris to Red Hat Linux for the Y2K boundary. Not too long after that, Red Hat dumped consumer support (handing it off to Fedora) to concentrate on Enterprise. Oops!
I'd have been happy to stick with Red Hat if they'd stuck with me.
I was a vocal opponent until i had to actually use and rely on it. I wouldn't go back if you paid me. It has made my job a lot easier.
How nice for you. What a pity your experience and mine are not the same.
We're seeing a.lot of flamage about the lack of security on IoT devices. One company I work with is making such a thing. The presence of systemd increases the expected scope of a security audit to the point that they expect to migrate the production version to another OS rather than absorb systemd by upgrading to the current version of the linux distribution they used for initial development.
The trick to remembering them is to have a system
On problem with systems is the wide variety of disallowed / allowed / required characters in passwords for various sites ("minimum of eight characters, at least one lower case, one uppper case, and one digit (but we won't accept puncuation marks and don't say that)"), in rulesets that are only displayed when you set the password, not when you enter it.
How convenient for "Internal Security" if every LG fridge, TV, or other appliance is a spy appliance.
How long before NSA has an exploit?
How long before your local burglar can get one off a web site, and use it to determine what valuables you have and when you'll be out of the house?
A language is thriving or dying by the number of inexperienced developper trying to learn it. If no inexperienced cev learn it... it is dying.
But your thesis ("[web searches for help on a language is] actually a good metric [for language viability]") doesn't follow from that assumption.
Other possible explanations include:
"The C language is easy enough to understand, compared to others such as java, that references to documentation and searches for arcane knowledge about it, even by noobies, are rarer."
"The ordinary documentation of C is clear enough that web searches are rarely needed."
and so on.
This doesn't mean that C use ISN'T declining. But it does mean that additional measures using different metrics would be required to determine that this result isn't just an artifact of the methodology.
it has no downsides I can imagine.
If generalized beyond patent trolling suits it could severely limit the ability of shallow-pocket plaintiffs to obtain legal council on a contingency fee basis to obtain redress for the torts that damaged, and perhaps impoverished, them.
The result would be that the legal system becomes accessible only to the rich.
Most of the high level stuff will have decayed significantly by then. Send workers in, chop up what's left,
Fine so far.
seal it up in drums and throw it in an abandoned salt mine.
Definitely not a salt mine. The US used to consider that (or salt domes). Then they figured something out:
The heat (and even a little builds up) causes water to migrate through the salt to the heat source. Then you've got hot stuff sitting in saturated salt solution. This has lots of opportunity for exciting failure mechanisms.
Once the stuff is out of containment, the water-soluble part has the opportunity to spread through the whole salt deposit, which might be very large (such as the remnant of an ancient inland sea that dried up). Note that small amounts of chemicals dumped in salt mines under Midland Michigan showed up in the salt mines under Detroit.
Once the high-level stuff has decayed enough that the stuff is reasonably safe to handle, it's potentially very valuable, and might be made into useful artifacts in as safe a manner as tech in the 2100s can manage. For instance, this was a graphite moderated reactor, so there's a BUNCH of carbon 14 in there. It could be made into things like the diamond-based nuclear batteries (low power, safe to handle, with lifetimes longer than human civilization so far) that were discussed here last month.
In another hundred years or so who knows what the technology will be capable of? You can predict that it will be a LOT better. But you can't predict exactly what it will BE. (If you could, you could do that stuff NOW rather than waiting for the breakthroughs. B-) )
