Geeze, Australia doesn't have this or that amendment to the constitution - Guys we ARE NOT a state of the USA. We have our own laws, and currently (legal) gun ownership is restricted. Frankly I believe that Australia is generally a safer place since the Howard government restricted legal gun ownership. Yes I know I'll be modded down and adversely commented on by those of you in the US who have the "right to bear arms", but frankly I don't give a flying fuck about your rights - I'm only interested in my rights and the safety of me and my family. So yes 3D printed guns should be banned here in oz. And I know that I'l get the storm of "yes but the crims and bikie gangs can get guns". Yes they can, and as far as I'm concerned they can go and shoot each other.

Coward! Windows Movie Maker actually interprets(some) standard formats, and has an interface that feels like having a pro editing studio at your back compared to the horrors of Sony Movieshaker!(Even better, Movieshaker is exciting and mandatory if you were... questionably sensible... enough to purchase one of Sony's pricey 'MicroMV' cameras, which were vaguely DV-like, except totally incompatible.)

With jpeg(and I think at least some of the mpeg flavors), quantization matrices can be your friend.

Different hardware and software uses different matrices. This isn't a slam-dunk(if somebody just lightened the image a bit to bring out the detail, the quantization matrix would scream "Photoshop!", despite that being pretty innocuous); but it makes it rather harder for a clueless faker to simulate a 'right off the camcorder' "authentic" video if the last compression was almost certainly performed with editing software.

Depending on the details of the format, there are likely to be a variety of other things that are optional or implementation-specific(at least within certain ranges) that can be examined to try to source a given file. If implementation(or quality level/encode settings)-specific details vary between sections of the video, or between parts of individual frames, that's probably a bad sign.

If you have enough footage, and ideally access to the alleged source hardware, you can also attempt to characterize physical defects in the sensor. All digital image sensors, to one degree or another, exhibit imperfect linearity. Some pixels are 'hot', some are abnormally insensitive, this is especially visible on long exposures, or in very dark scenes, where the hot pixels tend to stand out. Onboard image processors have gotten increasingly good at squelching minor sensor noise, so this isn't easy; but a given CCD or CMOS sensor will have a noise pattern that is extremely difficult to replicate. It's just an open question whether you'll actually be able to see enough noise to identify it.

Why is it a bad decision? The more advertisers know about me, the more likely I am to see ads for things I am actually interested in.

I do hope that none of your interests would be worth more to your insurer, potential employer, or other interested parties than they would be to doubleclick...

I'd argue that the behavior described can't (without doing serious violence to the details) be usefully dismissed as 'making bad decisions'.

Yes, unfortunately, Kids Today show no more signs of being Valiant Defenders of Privacy than did people yesterday. Outside of a principled-but-largely-ineffective minority, nobody ever has. Unshockingly enough, they've largely succumbed to the nigh-inevitable when it comes to advertisers and analytics creeps watching everything they do.

On the other hand, they do appear to be taking some degree of protective action against authority figures who are overt enough to be obviously worth evading(parents, principles, coaches, etc.) and dumb enough to be evadable(If you plan on using the internet in a remotely ordinary fashion without Google, Lexis-Nexis, your friendly local telco, and possibly a three-letter-agency or two, good luck with that. If you are trying to communicate with your friends without your parents catching on to what exactly you are drinking, that's still possible).

Whether GP was joking or not, you have to wonder if the pharmas won't try something analogous to clawing public domain works back under copyright. Which, as any dipshit can tell you, should never happen. Except it does.

I'm sure that they'd love to(though TB is kind of a lousy disease as ROI potential goes. Virtually all the cases are in poor or marginal populations, so the customers tend to have only enough money to sporadically take drugs and develop resistant strains, and the first-world high rollers are negligible. Also, because the morbidity and mortality are so significant in poor countries, and the public health concern over drug resistance so great, a new TB drug would be an attractive target for generic production under the authorization of various uppity countries who don't understand that obeying American IP law is more important than their citizens' lives*shakes head*), I'm just not sure that they'd achieve much traction in a case like this. Unless therapeutic use does require some genuinely novel tweaks, the fact that synthesized vitamin C was big news in the early 1930s, and research on dietary sources was largely nailed down in the days when keeping the sailors on your man-o'-war from dying was important national security stuff, will probably mount a fairly stiff prior-art challenge.

Is there any reason to suspect that Intel is withholding any assistance that Apple is requesting?

Since they are actively working on an OSS driver, they clearly don't have some sort of 'zOMG Intellectual Secrets!!!' concern(and it's not as though Apple would be averse to signing the NDAs in any case), and Apple buys a lot of Intel chips(including a pretty good mix of the higher margin ones. They don't move Xeons for shit; but they also don't ship anything lower-end than an i5. That's not the sort of customer you play petty little games with when it comes to engineering support.

I was about to comment the same... With an "aPauling" pun. ;-)

Really, this will likely be quickly quashed by the Pharmas. Or they will patent a delivery transport - with the only FDA-approved administration protocol.

Unless the delivery transport makes a clinically relevant difference(in which case it would be as deserving of a patent as any medical innovation), how would patenting a transport help them?

Vitamin C is easily available in a number of flavors, some not by prescription, some of the more injectable ones possibly prescription only, and any doctor authorized to prescribe anything can 'off label' pretty much anything that won't either have the DEA on his ass or get his malpractice insurer to cancel his policy...

OK, so you're using my #2 example "things I can't explain with the currently known science".

I'm not saying vampires are real, I just don't like term "supernatural" as it's being thrown around without any sensible definition. Go back a few hundred years, and lightning didn't have a scientific explanation; many people probably attributed it to divine powers. Yet it was clearly a natural phenomenon.

I guess my point is that something either exists or it doesn't. "Supernatural" is a rather loaded term for something that simply doesn't exist. (Of course, I'm not perfectly sure that vampires don't exists, but if they did, there would be nothing supernatural about them.)

CPUs are magnitudes faster today than they were 10 years ago. Why is it that pages still take seconds to load? Go back 10 years and they still took the same amount of time. Why?

I'd assume that web devs(and their bean-counter overlords) are calibrating to user demands, not to the absolute objective of cutting down load times.

More bandwidth? Hey, we can replace all those 256-color .gifs and solid backgrounds with non-crunchy jpegs! More still? How about some Flash videos? Ooh, faster CPU? If we just load 20kb worth of javascript we can do all kinds of things without the old forms/refresh dance by doing xmlhttprequests and twiddling the DOM...

If you were content with the web page of 10 years ago, on today's hardware, it'd likely load like a bat, with a jetpack, on amphetamines, out of hell. It would also be comparatively spartan(though, given that much of what we have today is a nearly proper superset of ten years ago, there wouldn't be much stopping you from doing 10-year-old page styles on modern browsers.)
