Bellard Creates New Image Format To Replace JPEG

jaa101 Re:BPG natively supports 8 to 14 bits per channel (377 comments)

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

Bellard Creates New Image Format To Replace JPEG

jaa101 Transparency is supported. Pronounciation? (377 comments)

Note that, according to the BPG web site, "An alpha channel is supported" so BPG has transparency.

How are we going to pronounce this thing? "Bee-Peg" I suppose since "Bee-Pee-Gee" doesn't roll off the tongue.

Looks good.

Bellard Creates New Image Format To Replace JPEG

jaa101 BPG natively supports 8 to 14 bits per channel (377 comments)

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).

Australia Pushes Ahead With Website Blocking In Piracy Fight

jaa101 Re: Halfwits indeed (100 comments)

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.

https://books.google.com/books...

"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."

Australia Pushes Ahead With Website Blocking In Piracy Fight

jaa101 Re: Halfwits indeed (100 comments)

The term "piracy" has been used for illegal copying for over 200 years. Not saying it's appropriate but it's definitely established usage.

Virginia Court: LEOs Can Force You To Provide Fingerprint To Unlock Your Phone

jaa101 Re:Passwords Shouldn't Be Protected (328 comments)

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.

Virginia Court: LEOs Can Force You To Provide Fingerprint To Unlock Your Phone

jaa101 Passwords Shouldn't Be Protected (328 comments)

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.

Ask Slashdot: VPN Setup To Improve Latency Over Multiple Connections?

jaa101 Re:LACP (174 comments)

LACP is a layer 2 solution, i.e., it works at the ethernet level. The requirement here is for a layer 3 solution that works on the Internet. My guess is that there's nothing off the shelf so he'll have to start coding.

Apollo 11 Moon Landing Turns 45

jaa101 Almost Beyond Living Memory (211 comments)

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.

Eyes Over Compton: How Police Spied On a Whole City

jaa101 Re:Is it really much more than goes on already? (190 comments)

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.

Blender Foundation Video Taken Down On YouTube For Copyright Violation

jaa101 Re:Perjury? (306 comments)

Do we know this is the result of a DMCA request? Doesn't Youtube give studios like Sony an interface to take down what they want? So then it's back to being as annoying as hell but not legally actionable in any way :-(.

Your Car Will Tell You How To Hit the Next Green Light

jaa101 Tried Before; Doesn't Work (364 comments)

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.

Finnish Police Board Wants Justification For Wikipedia's Fundraising Campaign

jaa101 Finland is in the EU (252 comments)

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.

Panasonic Announces an End To Plasma TVs In March

jaa101 Plasma: better picture, worse choice (202 comments)

It's clear to me that plasmas give better quality image but I still choose LCD. The plasma issue of burn-in is the main worry but they're also more power hungry and heavy too. Plasmas easily beat LCDs for black levels, colour accuracy, response time and viewing angles but LCDs are good enough. Even if my kids didn't spend hours playing video games I know somehow there would be burn-in and then I'd want to buy a new set ... which is just a waste. Plasma being the losing technology is not all down to marketing.

Elon Musk Making a Working Version of James Bond's Submersible Car

jaa101 Cars Float, Submarines Sink (91 comments)

The fundamental engineering problem here is that cars float and submarines sink. Ballasting that car with enough weight so it's close to neutrally buoyant will ensure it performs nothing like a sports car on the road. This is the kind of issue that made lead acid batteries such a great choice for submarines in the first place.

The best approach is going to involve minimising the volume where water is excluded, i.e., ensuring that as much of the vehicle is flooded by water as possible when it dives. At least, as a sports car, the interior is very small so they may have a chance of making it work.

Dropbox Wants To Replace Your Hard Disk

jaa101 Re:Latency, latency, latency! (445 comments)

Just because a file is shared with Dropbox doesn't mean that accesses involve a network round-trip to their servers. The files are still stored locally (on an SSD if you have one) and only synchronised when a change is made on another machine. Dropbox is not the same as a Windows "network drive" over SMB/CIFS or Linux NFS.

Texas Poised To Pass Unprecedented Email Privacy Bill

jaa101 Re:This shouldn't be necessary (262 comments)

Apparently the trick in progress here is that people already gave their email to someone else, namely their service provider. The legal logic is that this borks their expectation of privacy, see http://en.wikipedia.org/wiki/Katz_v._United_States from 1967. One might hope SOTUS will revisit their decision in the light of the current state of technology but until they do you're stuck relying on legislative protect rather than constitutional.

Microsoft Pushes Skype with Windows Update

jaa101 jaa101 writes  |  more than 2 years ago

jaa101 writes "Came in this morning to find many of our corporate boxes sporting shiny new Skype installations. Looks like they've been pushed by Microsoft. We have a WSUS server so the administrators of that may have overlooked something. There's discussion at http://social.technet.microsoft.com/Forums/en-GB/winserverwsus/thread/74a93b2b-e820-40ef-a45d-2815b57d164e with Microsoft claims that they only pushed if there was a Skype installation there already ... and refutations. Maybe our SoE had something in it that fooled the updater but the affected machines had nothing like a working Skype.
Was Microsoft running short of Skype supernodes? I guess it's likely to slow down Windows machines with unwanted services and use plenty of unwanted traffic for both home and corporate users. And these will be people who haven't agreed to the Skype ToS! We're using XP but probably Vista and 7 are affected too. Please Microsoft, release a new update to remove these unwanted installations."

Australian ISP's Copyright Win

jaa101 jaa101 writes  |  more than 3 years ago

jaa101 writes "Medium-sized Australian ISP iiNet has won a copyright case against the major movie studios. Local studio Village Roadshow was joined by 33 others, including the US majors, in arguing that iiNet was not doing enough to stop its users pirating content. iiNet may have been chosen as a target big enough to set an example but small enough to beat. Today's victory was on appeal in the Australian Federal Court, confirming an earlier ruling a year ago that was won with costs."
