  2. Java Not Dead on Google Native Client Puts x86 On the Web · · Score: 2, Insightful

    Java applets are not "dead and buried". Neither on the Web, nor on mobile phones (with the distinction increasingly meaningless), or on embedded devices, like DVD players and settop boxes (most of which have Java VMs in them, especially Blu-Ray players and other HD players for menus).

    What is "dead and buried" is ActiveX, which is x86 code running in a browser's "sandbox". But even that is clearly no barrier to resurgence, as this story shows.

    x86 is a lousy architecture for modern purposes. Its design was determined by optimizations for executing Pascal programs, which was the primary programming market for the IBM PC when it was originally designed. That was a long time ago, and only the huge legacy of existing apps (and their forward momentum maintained by huge backwards compatibility design and sacrifices) keeps x86 code popular. I'm all for a SW x86 emulator, especially for newer CPUs so they don't have to be shackled to design compromises just to run the legacy code, instead of doing it newer and better ways with a more modern instruction set. Just like I'm all for the game emulators that will play old Atari 2600 games on Core Duo PCs and ARM mobile phones. Let's just not enslave ourselves to 1980 design priorities optimizing for a really dead language for yet another decade of programming, now going on 30 years, which is 20 generations under Moore's Law.

    One big difference between Iran and Kuwait is that although Iran warred with Iraq for control of the Basra area oilfields, Kuwait actually "sipped Iraq's milkshake" by drilling sideways across the Iraq border and actually sucked up Iraq's oil, which it sold to the US. Which was why Iraq invaded Kuwait.

  9. Massachusetts Just Decriminalized Marijuana on Time To Discuss Drug Prohibition? · · Score: 4, Insightful

    This past Election Day, the people of Massachusetts just voted 2:1 to decriminalize possession of up to 1 ounce of marijuana (over 50 typical joints). If caught with that much pot, the "criminal" is issued a ticket, about equivalent to a ticket for an open container of beer, that can be mailed in with a $100 fine without even a court appearance.

    Every day that goes by without Massachusetts falling into chaos or bedlam will prove how stupid pot prohibition is. Something like 50% of America's over 1 million imprisoned criminals committed nonviolent drug crimes, and about 850,000 people are arrested for pot every year. Instead of spending an average of $30,000 per year per prisoner, we could be collecting income and sales taxes from the people growing, distributing and consuming it. Probably could be a top agriculture export for this country. And with an entire state running OK mostly post-prohibition, the counterexample in favor of sanity should be undeniable.

  10. Re:Monopoly on Why Clearwire's 4G Network Plan Is No Slam Dunk · · Score: 1

    If you want a 4G network, there is no competition. That is a monopoly. It's like if the only broadband were AT&T, but somehow 56Kbps dialup meant AT&T's broadband weren't a monopoly. If some other competitor rolled out a 4G network, that might represent a different kind of monopoly, a duopoly. And if those two 4G competitors locked out the other network from their subscribed equipment, that would be a lockin monopoly just as the current Sprint/Verizon/T-Mobile/etc each are.

    To see the difference, look at the Internet connections available in a "telecom hotel", where many interoperable networks actually do terminate for customers to choose from, that are all in the same class of service. A customer can connect to one of them, or multiple, depending on the differences between them. That kind of free choice is completely different from a customer for this first 4G network. And the different 3G or 2G mobile networks are themselves a lot closer to the monopoly than to the free choice.

  11. Monopoly on Why Clearwire's 4G Network Plan Is No Slam Dunk · · Score: 2, Interesting

    This new network will be a monopoly, even more than the current mobile telco monopolies (lockin). At least on the current mobile networks you can roam on a different network, even though each network can use its monopoly of access to it to set prices and policies arbitrarily expensive and restrictive. For comparison, see the Internet backbones, which are comparatively cheap and open (even though the telcos/cablecos are increasingly coordinated in a cartel, abusing openness and fixing prices).

    Of course the first of anything gets to be a monopoly, especially when there's no "photo finish" race among competitors to be first. And the early adopters will pay whatever cost is required. That monopoly might even be necessary and acceptable for a while. But the incumbent mobile telcos have shown that the monopoly lasts forever, even if there are competing corporations (each with their own monopoly).

    These networks are all courtesy of the public, especially the mobile ones that lease the public airwaves. Those leases should include a public/private benefit formula that accounts for investment and risk by the spectrum developer, allowing monopoly control long enough to protect profit enough that investors are encouraged to go for the gold. But once some range of motivating profit is achieved, equal access and price anti-gouging rules should protect the public from the monopoly, protect the market from the monopoly crushing any competition entering. Perhaps the lease price should include a refundable deposit that reverts to the spectrum developer once competition is achieved, and is used to fund competitive entrants (under equal access and price protections) if the way the developer runs it doesn't allow competition soon enough.

    Make the incentives and protections for competition match the environment, and the market will run properly. Otherwise, we're just going to pay retail for a fourth generation of the telco monopoly that interferes with all our other development, exploiting public property for a very narrow private gain.

    So since we've got some tiny islands that N Korea could barely reach if it got really lucky, that N Korea could benefit from attacking only by escalating a shooting war with the US, we should... polish the trigger and load the gun?

    If N Korea could hit something that actually damaged US ability to counterattack militarily, economically, or - last resort, like always - diplomatically (like cut off their trade with all their neighbors), then we might want to consider an antimissile defense. But the Aleutians are a buffer against such an attack. If they hit them, we'd suffer minimal loss, and N Korea would finally find itself facing the most global opposition possible. It would be a boon to the US, just as Georgia's attacking Russia finally gave Russia the chance to slap down its Georgia nuisance.

    Because the US, unlike N Korea, has plenty of reach anywhere in N Korea, once the nice guy gloves are off. And N Korea, unlike the Aleutians, is full of targets useful for destroying its regime.

    In case you missed it, I'll make it plain: an antimissile defense of the Aleutians from N Korea is precisely the worst distraction from the proper, conventional response. Even plainer: exactly like invading Iraq when a couple dozen mostly Saudis attacked us from an HQ in Afghanistan protected by the secret police in Pakistan, antimissile defense of the Aleutians from N Korea is a bait & switch that would just squander everything, including unprecedented world alliance, to make everything worse, with no way out.

    The flatness of the surface isn't really a problem, because the photons that arrived a little later (by speed of light, the distance of the "roughness") are going to be extremely similar to the ones that arrived at the time of the first photons reaching the closer parts of the roughness. In fact what helps us is our tolerance of a somewhat soft focus. Since our resolution is 10cm, which light travels in 3.33564095E-10 seconds, our probably much longer exposure (to collect photons) means our focus is not going to be precise anyway.

    The main problem, bigger than reconstructing the image that didn't pass through a collimating (projecting) lens (though the atmosphere's curvature might give us something to work with, however fuzzy at the "boundary" with vacuum), is indeed all the other light on the reflecting object. We could probably filter that by spectrographic filters, though we'd be guessing at the precise spectrum of the ancient light of the Sun.

    This whole thing would be quite a feat, at every step. But it does seem to be within physical limits. So given enough time to work on it, "we" might eventually pull it off.

    You're getting double the information by using two telescopes. Most of the info is redundant. But there is phase info, available to the "phased array", in what you're getting. The interferometry is the method of extracting the phase info. The phase info isn't redundant between the two telescopes. So that extra info is an increase over the single telescope's.

    I didn't know about McDevitt's version of this idea. I thought of it when thinking through "faster than light travel" applications, when I realized that reflected light "bends space" back to the source, which is effectively time travel. I was helping build a digital camera out of a lot of cutting edge DSP for noise reduction and feature enhancement, including some efforts at reversing the effects of air turbulence confusing light paths to the sensor. It occurred to me that similar processing, but more advanced, could "clean up" the reflections of Earth from distant objects. Pluto is frozen and kind of "shiny", and by extension so are other distant objects. The computation might be far too vast for our current computing methods, even if all of our computers were dedicated to it. But quantum computing methods, especially in later generations (harnessing all the subatomic particles, not just the "big" ones and their simplest quantum states), could deliver the power.

    It's certainly worth thinking about. Because if it worked, the value would be unprecedented. Age old questions, some religious (various miracles), some political (conduct of ancient original conflicts), some scientific (video of ancient ecologies), and others of wide impact, could be settled with visual evidence understandable to anyone (if sufficiently reconstructed). And if we're ever going to do it, we're going to have to think about it a lot before we get there.

    If only we could reverse the technique, and peer at very close objects to see the future, we might learn quicker how to look at the past :).
