  2. Bandwidth throttling on New Legislation Could Eventually Lead to ISP Throttling Ban · · Score: 1

    The problem, in my opinion anyway, isn't bandwidth throttling per say. It's *selective* throttling of certain protocols. That's tantamount to censorship.

    What they should do, providing they don't actually have enough capacity to guarantee the bandwidths they sell, is clearly specify a minimum guaranteed bandwidth (in absence of equipment failure) and a percentage of time that the rated bandwidth is typically available. E.g. "10 Mbps connection (min 2Mbps, full 10Mbps available 90% of the time)". It would be preferable that these items were shown up front and not buried deep in the TOS. This would probably require government intervention of some kind, however. (And, IMNSHO, that's EXACTLY what a government should be doing - regulations that protect consumers and increase competition through transparency of offers.)

    Regardless of how often throttling is done, it should always be protocol-neutral and user-specific basis. I.e. no throttling Bittorrent traffic on your backbone just because that's the easiest thing to do. No, you need to throttle each consumer individually (neutrally), basically giving them a slower connection for a (hopefully short) while.

    Oh, and throttling ISN'T done by faking packets! That's fraud and should result in heads rolling, even though sending people to prison for wire fraud over it is *probably* overkill.

  3. White LEDs are different on DOE Shines $21M on Advanced Lighting Research · · Score: 4, Informative

    And, no, LEDs are not fluorescent. Fluorescent bulbs stimulate mercury to emit UV light. The UV light hits the phosphorus which makes it fluoresce and produce visible light. LEDs work by jumping electrons across a band gap and a photon is emitted when it jumps back down. The high efficiency comes into play because it doesn't take much more energy than that of the band gap to make an electron jump.

    *White* LEDs don't work that way. You might assume that white LEDs are simply three (or more) normal LEDs combined in a single package. While it is possible to make white LEDs this way, it's not the method usually used (for several reasons, including "color integrity").

    Instead, white LEDs are typically made by coating a BLUE indium-gallium-nitride (InGaN) LED with phosphorous. This is not all that different from a fluorescent bulb, which is what the GP postulated.

    Different color temperatures can be achieved by varying the phosphorous coverage. Lower coverage lets more blue through (cooler temperature), whereas higher coverage causes more blue to be absorbed and thus more of the phosphorous emission spectrum to be emitted. The dominant line in the most commonly used phosphorous for LEDs is around 580nm (yellow).

    It's also possible to get white LEDs that are made by coating a near ultra-violet LED with phosphorous (thus getting even closer to the fluorescent bulb of the GP).

    This might change in the future, with serious work being conducted in the field to improve on reliability, efficiency and color characteristics. To the best of my knowledge, however, none of the new methods (go search for yourself) are commercially available and as we all know, many things that seem promising in the lab never make it to market for any number of reasons.

    For reference, red diodes emit at ~ 630nm, blue diodes at 470nm, green at 530nm. The exact wavelength of the emitted light depends on the materials used in the LED, of course.

  7. Re:What about a new password element? on W3C Publishes First Public Working Draft of HTML 5 · · Score: 1

    Why do you want to do that in HTML when HTTP already includes a number of authentication options, including digest passwords and more complex schemes?

    By that logic, why even have a password type at all?

    The answer, of course, is that everyone uses it, because it integrates well with page designs.

    You can either be stubborn and admonish everyone else from your high horse... or you can actually go about trying to make things work for people. On all the sites I've made, I'm already securing passwords. Random salt is generated for EVERY user and a hash is made of the users password + the salt. Only the hash (and unique salt) is stored, never the password.

    But considering the number of sites that allow you to get a copy of your password emailed, I can tell I'm among the few who do it this way. So instead of sticking my head in the sand (yeah, I'm mixing metaphors - wanna make something of it?!), I propose a solution that everyone can easily use.

  10. Re:What about a new password element? on W3C Publishes First Public Working Draft of HTML 5 · · Score: 1

    What the browser sends to the server IS the effective password. If the user types 'secrit' and the browser sends hash('secrit'+'salt') to the server, then that hash effectively -is- the password.

    I'm well aware of how this works. The advantage, as I tried to point out, is that only THAT PARTICULAR server is then compromised. So if you got hold of Regular Joe's football fantasy message board password, you would only be able to log in to that one server... and not all the others where Joe used the same username and password.

    The REUSE of passwords is the problem that is solved here.

    Referring to my initial post, only the HASH of the supersecretpassword is revealed to the site (and anyone who gets hold of the passwords from it), not the supersecretpassword itself.

    That would be a HUGE step up in security from where we are now.

  11. What about a new password element? on W3C Publishes First Public Working Draft of HTML 5 · · Score: 1

    My greatest wish in HTML5 is a new password element. One that uses a standard hashing-algorithm with server-supplied salt (optional local pepper could be provided) and prevents the receiving site from ever getting the password that the user actually typed in. E.g.

    Here the contents are of the above handled completely by the browser, without the possibility of the site to get access to the contents or record keystrokes (via event handlers like onChange) while in focus. The *submitted* password would then be a hash, with salt provided by the server, of the supersecretpassword.

    While not foolproof, it would help immeasurably with password security on the web. Even if no local pepper were added, anyone who gained access to the password database of the server (e.g. the owners), it would force a brute-force attack on the password.

    No longer would anyone with access to a password database from a random web server (e.g. forum) be able to access pretty much every other site the users are registered on - because we all know that only rarely does Regular Joe use anything but his one-and-only password. This is especially bad when financial sites are included, but even if it's just gmail/yahoo/hotmail/whatever, that's still plenty bad.

    Photoshop is the default application for doing any kind of drawing or photo editing. It might be total overkill, it might not be the best choice or whatever, but that's irrelevant. Ask yourself this instead: How many people do you think PAY hundreds of dollars for Adobe Photoshop for their own personal at-home use?

    Face it, Photoshop is the standard because it's pirated so much. This isn't a question of "lost sales", since 90% of Photoshop pirates (and I'm extrapolating from people I know of, so flame away) wouldn't DREAM of laying down that amount of cash. If they were forced to go legal, they would probably buy Paintshop Pro - an application that probably suits their needs much better anyway. (So if anyone is losing sales when Photoshop is pirated, it's probably Corel).

    To summarize: GIMP competes primarily with *illegitimate* Photoshop users.

  13. Millions of sheets of A4? on The Afterlife Is Expensive for Digital Movies · · Score: 1

    Not being sure if this is meant to be funny or not, I'll provide a little math:

    "Watercode" (a high density 2D barcode) is rated at 440 bytes/cm2 (Microsoft has a color 2D barcode which has maybe a 25% higher data density).

    Disregarding the fact that you'd probably be storing the data on drums of paper, and not sheets, what follows is a calculation of the number of A4 sheets required to store a movie in original format.

    A4 is 210x197 mm2 = 413.7 cm2.
    At 440 bytes/cm2, that's 440*413.7 bytes/A4 = 182028 bytes/A4 ~ 0.2 MB / A4 (with very generous rounding up, so it covers the MS color barcode as well).

    At several TB for a digitally shot movie master, that's... well... a lot. More than 5 million sheets of A4 paper per TB, in fact.

    I'm not going to get into the whole weight or storage space issue here, let's just agree that's an unmanageable amount of paper...

    Feel free to argue that modern laser printers have whatever high resolution you feel like using.... but there's a reason no commercially available barcode has that kind of data density. If you feel the job can be done much better, I suggest heading down to the patent office...

    The point simply being that there are almost certainly circumstances under which ANY browser leaks memory. The circumstances likely aren't the same, of course, which is part of the problem and why different people have different experiences.

Real details of pages visited and actions taken on those pages. If there's a leak, it'll be reproducible. So log your visits (hey, "history") and try figuring out which ones are causing the problem.

    To see if the leaking is related to Javascript, try turning it off once you have found a reproducible case (which might be a huge list of sites of which only one might be the actual offender).

    How come my 700MHz Duron with 384MB memory ran Firefox perfectly? Never had any problems. At least none that were memory-related. I'm convinced that 99% of all the memory issues people THINK they have is because Firefox keeps allocating memory as long as the system allows it to... which is the right thing to do! If you buy gigs of memory and the system isn't using them, why shouldn't firefox (or any other application) keep gobbling them up? Firefox releases the memory nicely again if the system wants it (e.g. you start up Open Office).

    Maybe it's your extensions or plugins that are causing the problems, if in fact you are experiencing problems?

    That's not to say that there are NO leaks. Of course there are. I've used IE many, many times where it simply stopped responding and had to be stopped. I've experienced the same thing with Opera, although far less frequently. The only times I've had to shut down Firefox has been due to plugins or extensions. Again, not saying there aren't real leaks and maybe you just happen to visit sites that cause these cases to occur, I don't know, but it seems quite clear that 99% of the problems people report aren't real (it's just a memory usage number, which is useless in many, many ways).

  16. Source criticism on Jimmy Wales Says Students 'Should Use' Wikipedia · · Score: 3, Insightful

    One of the most important lessons students can learn pre-college is, in my opinion, source criticism (a term which is unfortunately used mainly in a biblical context, which is NOT my usage here).

    "A critical mind is a questioning mind" is a good lesson and should be taught at every level of education.

    Virtually all sources are biased, in one way or another, and students need to be aware of this and treat the information in a manner befitting the source.

    Wikipedia is just another source (not a primary one, of course, with a few exceptions) and should be treated like every other secondary source - with skepticism. The fortunate thing about Wikipedia - and one that makes it a much better secondary source than most others - is that there are abundant links to other sources (although not necessarily primary sources, which would be preferable).

    Additionally, Wikipedia enables one to view the version history and a discussion of the article in question. This discussion can often be used to discern if there are any particular points of contention that one should be aware of. This shouldn't replace ones critical view of "accepted facts", of course.

    In practice, we are inundated with such an overwhelming amount of "news", "facts" or interpretations of same, that we cannot possibly be highly critical of every single item. Instead we rely on the reputation of the source. It is important, however, that we routinely question the reputation of the source.

    For teachers to ignore Wikipedia does not seem particularly insightful and one has to wonder whether the teachers in question are the same authoritarian breed of teachers that can wreck havoc on a young mind.
