Like I said, TIFF is a container format. Saying that TIFF supports BPG is just like saying that HTML supports BPG. It's great in principle ... until someone sends you a TIFF file that uses a codec that your reader doesn't support. So I genuinely have no idea; what's the current list of software like that will correctly handle a TIFF with a BPG-encoded image inside. For example, when did/will libtiff and Photoshop first get support?

I'm not saying that BPG files are any better in this respect at this stage, though the JavaScript decoder is nice. Obviously any JavaScript TIFF decoder would need to be _much_ bigger that the BPG

From the web site "BPG natively supports 8 to 14 bits per channel," which is a huge advantage. 8 bits is more of a straight-jacket than people realise and this offers a more portable way for people to pass around high bit-depth issues than camera raw files (proprietary things inside) or TIFF (a complex container format prone to cross-platform issues and poor compression).

Sorry, I was posting from a mobile so citing was not practical. See:

"A Treatise on the theory and practice of Seamanship", Richard Hall Gower, 1808, p. v-vi.


"In justice to the Author, it becomes necessary for him to state, that during his late voyage to India, Mr. Steel*, a bookseller, of Union-row, Little Tower-hill, republished nearly the whole of the 2d, 3d, 4th, 5th, 6th, 7th, and 8th chapters of the first edition of this work, in a voluminous Compilation termed, "Elements and Practice of Rigging and Seamanship." However illiberal such treatment must appear to the truly generous mind, the Author Would the more freely forgive Mr. Steel had he not* by artfully endeavouring to evade the piracy, been guilty of such misrepresentation, as has a tendency to bring his professional knowledge in question. Several deviations of this sort are contained in the 2d volume, 4to, of Mr. Steel's work, and are produced to shew that the Author has just reason for complaining."

I definitely agree that it should take more than a simple demand from police before you have to provide a password, or any other form of authentication, for access to your data. Glad I don't live in VA. My only point was that the root of the inconsistency here between biometrics and passwords can be traced to the idea that passwords have fifth amendment protection. There are definitely many issues with requiring passwords in any circumstances, including claims to have forgotten them and around steganography. Passwords have the advantage that, even if you can be legally required to give them up, there's no way to force you do so. The most they might legally do (one would hope) is have you rot in gaol indefinitely.

Comment: Passwords Shouldn't Be Protected (Score 1) 328

The anomaly here is due to the idea that fifth amendment protections should apply to passwords. Passwords can't be incriminating*; they only provide access to existing material that might be incriminating. There have been decisions both ways on this but my money is that eventually SCOTUS will rule that passwords are not protected.

* One potential loophole might be where someone claims their password itself is incriminating. I think the best solution here would be to allow "use immunity" for passwords and remove the rule about derived evidence for this situation.

The saddest part about this is that soon, probably, we'll live in a world where there's no living memory of what it's like to walk on another world. Armstrong and his successors are no longer young and none of the projects to return to the moon or to go to Mars look likely to happen quickly enough. Who in 1972 would have thought that they were watching the end or an era instead of the beginning? I don't think anyone's made it past 1000 miles up since then.

This system is going to see plenty of things that aren't "in public", even without peeping in windows. What is your expectation of privacy in your backyard? Could there be a constitutional up-side in the US though? Maybe everyone will be able to have their cases thrown out due to the warrantless surveillance conducted on them prior to their arrest.

This was trailed years ago in Melbourne Australia. As you approach the lights signs advise driving 60, 50, 40, etc. as appropriate but sometimes, show no speed. Drivers quickly learn that this means they need to speed to catch the lights ... so they do. Police don't like this so the trial is killed. There's no way to show legal speeds in a way that drivers can't figure out when it's best for them to speed. This can't work until we're all driving automated vehicles that set their own speed.

Comment: Finland is in the EU (Score 1) 252

If it's the police initiating this then they must feel it's a criminal matter and so extradition becomes a possibility, and Finland is part of the EU. If they want to play hard ball then Jimmy might have to cut down on visits to Europe because, once he's there, it will be European courts who get to decide who has jurisdiction.
