  1. Why believe warming is linear ? on Global Temperature Set To Reach 1 Degree C Over Pre-Industrial Levels (metoffice.gov.uk) · · Score: 0

    A greenhouse works by letting heat in (light) and not letting it out (glass traps convection). The atmosphere does so to some extent by letting energetic visible and shorter wavelengths through while trapping re-radiating longer (cooler) infra-red wavelengths. Fine.

    Carbon dioxide traps infra-red only on three wavelenghts (wavenumbers) corresponding to its' vibratory modes. This absorbance is proportional to incidence, not linear -- see the Beer-Lambert Law.. (Linear approximation works only at very low absorances).

    If you double the amount, you halve the transmittance. But even at 100 ppmv CO2, transmittance is only 10^-10 (what else would you expect from 1mm as solid?). The atmosphere is already opaque on CO2 wavelengths. The glass is already on this greenhouse -- another layer will do nothing measureable.

  2. Workarounds on EU Court: Commuting to Customer Sites Counts as Work · · Score: 1

    Like any law or ruling, there are certainly loopholes or workarounds. An obvious one would be to obtain a [small] office near/in the customer premises. Then the long commute is to this assigned business office, with a short hop to the customer.

    The real problem is you cannot legislate morality or fairmindedness. A market economy can balanece things to the extent competition operates. An unfair employer loses employees (a big deal in IT). However, the EU is especially keen to entrench "employee rights" and thereby lessen competition for employees. If you cannot fire, you will be very reluctant to hire. So the EU is stuck with regs upon regs.

  3. Re:S O V E R E I G N I M M U N I T Y on Ask Slashdot: Opinions on the State Breaking Its Own Law Against Employee Misclassification? · · Score: 1

    A good point even if it is reductio ad absurdam. The key concept is "due process". Yes, sometimes a goverment (really the adminstration) may have cause to break some laws in the furtherence of law enforcement. These should be strictly limited and subject to open judicial and legislative oversight. "Sovereign immunity" is the analog to writs of assistance (general warrents) which the Courts have partially quashed with the interesting doctrine of "fruit of the poisoned vine".

    ... look it up. The idea is that lawmakers are not bound by the very laws they write because they could have written themselves immunity. IOW, the boss rules.

    This is deeply unAmerican and rooted in fealty to power rather than all power flowing from the people and laws (& Constitutions) first and foremost binding governments. That states (and the Feds too!) [ab]use this convenient feature merely shows them to by tyrants, perhaps fearsome but unworthy of respect.

  5. Call for martyrs! on America's Technical Debt · · Score: 1

    The request for more STEM people in politics is analogous to asking for more "people people" (PHB) in technology. Nasty and counter-productive beyond those necessary for I/O interface.

    Different people have different personalities and predilections. Tech people like manipulating technology (molecules, electrons, logic). They would be devoured by politicians who devote the same effort into manipulating people. (Often, but not always, to their detriment.)

  6. N.Korea has'em ! on Iran Has Signed a Nuclear Accord · · Score: 1

    If N.Korea has nukes, why do you think that Iran does not? It has 4-5x the size (pop, GDP) and by comparison with NK would already have them if it wanted. Pakistan is another comparable.

    This is at best an agreement not-to-test, slowing? development of fission-fusion warheads. Just what do you think heavy water reactors are for? Canada sells CANDU tritium for US warhead refreshing.

  7. French prosecutors discover VPN on France Claims Right To Censor Search Results Globally · · Score: 1

    ... news at 11 :)

    Look at it from their PoV: the French have a law, and their civil-code attitude to the law is to enforce on principle, not to the letter as English common law. Loophole closing rather than toleration (which might be applied wholesale to certain violators.)

    Some well-intentioned person probably argued against RTBF by pointing out that VPN bypasses geolocation. So the Prosecutors were informed and instead of abandoning an impractical (if not stupid) law, they figured out how to close the loophole.

    Les procureurs [correctly] figured they could not stop VPNs, but Google was there for the muscling. Like all impractical laws, even worse measures are required for enforcement (eg.drugs).

    It will be interesting to watch. The French and EU courts could go either way. At one extreme it is an act of war (blockade) and the other Google leaves France. Most likely a deal for a hidden something France wants.

  8. Why high power ? on Ask Slashdot: What Hardware Is In Your Primary Computer? · · Score: 1

    FWIW, for my main desktop I run a nice cute ECS Liva (dual 1.7 Celerons, 2 GB RAM, 16 GB flash 3W). It replaced an Asus 900 Mhz EEE 10W. This machine is up 24/7 along with a few headless power-sipper Atoms & Raspberries. Fit for purpose

    I have some compute monster 3 Ghz quad 16 GB, but they seldom see power more than once per week. Just not needed unless I have a big job like transcoding GBs or a major project build.

    .
    For me, instant availability is worth more than wait-time. In fact, I would rather wait and know I've got a bloated page than have the flash whiz past. More important are the HID -- like a great screen (I prefer portrait 1200x1960) and good kbd/mse.

  11. B I N G O ! on Judge: Warrantless Airport Seizure of Laptop 'Cannot Be Justified' · · Score: 1

    People do not realize the US has always exerted strong export controls. These accelerometers are most likely ECCN 7A001 (maybe 7A101) and software for their control 7D001 and drawings/specs 7E002 . All highly controlled.

    I see no legal reason the border search exemption should be symmetric (incoming/outgoing) since the consequences are different -- inbound contraband can always be later seized; what is lost to outside is gone. DHS should have searched laptop and seized it if controlled material found (as in imminent danger of being experted.) Copy & release was very wrong.

    I strongly suspect this ruling will be appealed and overturned, at least in part.

    When advocates make inflammatory claims that have innocent explanations, I consider them confidence crooks. They know their best arguments and have made them. Yet another example of lies being more revealing than the truth (so long as you already know it.)

  14. Intimidating Cops guilty of assault with firearm ? on What To Say When the Police Tell You To Stop Filming Them · · Score: 1

    Most cops are polite -- with good reason: If anyone approaches you in a menacing tone, stance or attitude, they _are_ guilty of assault, with firearm if armed. Cops have no legal immunity except when arresting. Assault is the _threat_ of violence, battery/mayhem is the act.

    With confidence they will not be prosecuted, some cops push the line. They make forceful requests they mean to be taken as orders. (Plausible deniability) One remedy is to ask: "Is this a request or an order?" "Will you use force if I refuse?" A longer-term remedy is to remove the cofidence, and particularly to have bad cops fear indictment by untampered grand juries and conviction by un-behelden prosecutors.

  15. Technically possible ? on French Version of 'Patriot Act' Becomes Law · · Score: 1

    Leaving aside all the political questions, I doubt blackboxes are _technically_ possible. The summary said "communications from customers", so that means upstream traffic. With cloud sync data (especially of photos/vids), that's _a_lot_ of data:

    Say uplink is 10 MB/d per user. Over 40M users that is a manageable 400 TB/d, but these laws typically have retention periods, 6 mo being the shortest. That takes 73,000 TB which even over a few dozen ISP sites is a major undertaking. Metadata is ~1% so might work. Download is 50+times so would not.

    Should this mem watching ever become a threat (keystroke time-gap reading?) then an easy counter-measure is to detune the high-res timers, say zero out the lower 24 bits of rdtsc() in the JSlib. Still leaves ~10ms resolution but will break any attempt to time cache-reloads.

    I said nothing about combat being allowed. You assume a "Wild West" lack of law enforcement.

    I would consider current [techno-]society as very much homo-sapiens "in the wild". Any outside influences/zookeepers are carefully hidden :)

    But I agree hunter-gatherer societies find other traits more advantageous. Even industrialized societies have lower intelligence advantages than information societies. "Mate attraction" is obviously a second-order effect with lags (it is what used to pay). We are 10 generations into the start of industrialization but only 4 into info.

    The gross advantages of intelligence are quite apparent and quite large. That intelligence is only slowly taking over implies the net advantages (after deducting disadvantages) are much smaller.

    If high intelligence were an unmitigated benefit, natural selection would have moved the IQ average to 130, 150 or whatever over the eons. There _must_ be commensurate down-sides. Depression? Slower reflexes? Go fetch!

    As it is, we just have the Flynn effect of average IQs rising about 1 pt per decade over the past century. That might [or not] be considered as fast evolutionary change.
