  1. Re:So can someone answer this: on HDCP Master Key Revealed · · Score: 3, Interesting
    From what I understand,the leak makes revocation useless:

    "The master key allows you to recover every other key in the system and lets you decrypt [HDCP video content], impersonate a device, or create new displays and start selling HDCP compatible devices."

    While [Intel and content providers] are spending millions on HDCP, he says, they will be denied the benefits of research that can help fix the technology. Ferguson predicts that a year from now, someone will post a HDCP master key on the Internet, and the money spent on the system will be wasted.

    Upgrading the firmware of players to disable HDMI altogether isn't possible at this point. I'm not sure of the exact process, but since you can make new displays, you can create a device that just makes up a random one if it doesn't handshake in five seconds. Also, you can impersonate any existing device- and blocking every existing monitor on the market isn't feasible either.

  2. Not yet there on School Swaps Math Textbooks For iPads · · Score: 1

    I could buy an iPad with the money I have but I'll take a regular textbook any day, namely because they can't take the book away from you.

    Additionally, the hardware is more of a novelty than anything else at this point- too expensive, too fragile (especially for middle schoolers), too much of a target for theft, and not advanced enough.

    The textbook companies love this concept, since it kills secondhand ownership. You can sell licenses to eBooks just like software!

    Also, math input without a stylus or keyboard (and I doubt they're teaching LaTeX for any sort of efficient math input) can't be fun.

  3. Re:What will they do with the money? on Skype Files For IPO · · Score: 5, Informative
    The SEC filing (part of the summary) states that the money from the offering will be used for "general corporate purposes", but this becomes more interesting when put in perspective of their prospectus, where they want to grow in four areas:

    First, we believe that there is a significant opportunity to grow our user base.

    Yawn. Most companies are going to claim this. Next!

    Second, we believe that we can generate more communications revenue from our users by improving awareness and adoption of our paid products and introducing premium products such as group video calling.

    They want to charge for video calling, even though Oovoo and others offer it for free? Good luck, unless you're going to split it into free group calling or do a freemium model (certain group calling features are limited to paid users).

    Third, we will continue to develop new monetization models for our large connected user base. We currently generate a small portion of our net revenues through marketing services (such as advertising) and licensing, which we expect will grow as a percentage of our net revenues over time.

    They want to make more money off of the people who aren't paying for Skype. I predict more ads and third party ads within the Skype application.

    Fourth, we will broaden our user base to include more business users. For example, we have recently released and will continue to develop and market Skype for Business products that aim to capitalize on demand for Skype from small, medium and large businesses.

    This is where the money could be useful: scaling up development and investing in new technologies and getting businesses aware. This requires people and time, which takes money. Right now, Skype isn't big in the corporate world from what I've seen, with big warnings from my company not to install it (and heavy filtering on anything Skype related). If they compromise and possibly allow a business client that keeps within the network for anything that isn't a call to an outgoing line (and maybe integrates with the desktop app), I could see Skype getting a major foothold.

    Just some observations. I'm not wowed by this IPO either, and the lack of specificity of how they're going to spend the money makes me wonder if they've even gotten that far yet.

    The laughs will come if consumers decide that they don't care and buy the phone anyway despite headlines saying how Motorola has put a self destruct chip in the phone. The carriers will probably play hardball with every device manufacturer and get this technology in every Android phone so they can brag about an open platform but lock down the updates and stop providing Android updates a year after the phone is released.

    If consumers ignore the Droid and other phones that implement such anti-consumer chips, then it'll be a victory for Android users, resiting attempts to take away from the openness of the platform.

    eFUSE can be used to change chip logic on the fly based on the operation,, or, as Motorola is using, can be used to modify the programming of the chip itself to render the device nonfunctional without a reflash.

    If you could figure out the necessary code to flash to the chip - which wouldn't be easy - yeah, you could reflash the chip via the JTAG port.

    Given that HTC and others aren't locking the phones down in a method where the phone deliberately tries to use a device to brick if the phone's firmware/kernel/bootloader is not official, crackers are more likely to ignore the phone. And given the publicity ("Motorola phones have chip that self destructs"), ordinary consumers could be scared off too.

    Motorola acknowledged this back in February:

    We understand there is a community of developers interested in going beyond Android application development and experimenting with Android system development and re-flashing phones. For these developers, we highly recommend obtaining either a Google ADP1 developer phone or a Nexus One, both of which are intended for these purposes. At this time, Motorola Android-based handsets are intended for use by consumers and Android application developers, and we have currently chosen not to go into the business of providing fully unlocked developer phones.

    The use of open source software, such as the Linux kernel or the Android platform, in a consumer device does not require the handset running such software to be open for re-flashing. We comply with the licenses, including GPLv2, for each of the open source packages in our handsets. We post appropriate notices as part of the legal information on the handset and post source code, where required, at http://opensource.motorola.com./ Securing the software on our handsets, thereby preventing a non-Motorola ROM image from being loaded, has been our common practice for many years. This practice is driven by a number of different business factors. When we do deviate from our normal practice, such as we did with the DROID, there is a specific business reason for doing so. We understand this can result in some confusion, and apologize for any frustration.

    Even the official builds from Motorola allow you to install APKs not blessed by Google, correct? So what reason would Verizon have to block a small but vocal minority from getting super geeky with their phones? What reason would Verizon have to say "don't allow non-official firmware"?

    If you're going along with the theory that they'll stop Android upgrades as a reason to upgrade, I doubt it'll work. The headlines I'm reading now are "Motorola puts self destruct chips in phones", not "Droid X does not permit reflashing." These are the headlines that scare regular buyers away.

    Even if the nerds are a minority of your buyers they're still the group that people come to when they want to get a new phone. Given the lockdown, would you recommend a Droid X to anyone, even if they weren't planning on unlocking it? No, out of principle, and the fact that there are numerous other great options for Android, I would recommend someone against buying a Motorola phone at the time being.

    eFUSE is a chip technology developed by IBM is a special type of chip where the code isn't completely static- based on the operation of the device, an eFUSE can blow itself. This can reroute the logic in a variety of ways, or be used as a self destruct mechanism.

    It's reversible, but only by Motorola directly via JTAG. They have the custom code needed to flash the chip back to its original state.

  18. Re:Neglect the benefits & tablets win... on Prices Slashed For Nook, Kindle E-Readers · · Score: 1

    When making a comparison, how can you ignore the ONLY benefits of the e-reader (e-ink, battery life, and the free data on some models)? Tablets win for the same thing that all superior products win: for anyone looking for MORE than a decent platform for reading text, e-readers suck. If that's all you want to do, that's great, enjoy your e-reader. The price cuts certainly help. The problem is that there are *so many* disadvantages to an e-reader that you're neglecting, along with a complementary list of advantages for tablets.

    A tablet does many things well. The eReader is cheaper and does one thing well. As I said, the iPad will have its fans, but there will be people who want a single purpose device.

    Of your four "advantages", two are restatements of each other (battery life is a function of power draw) and one is highly subjective at best ("easier on the eyes").

    Not the same point. When you are sitting reading a page on the iPad, you are using just as much battery life as when you flip the page. Whereas you can leave an e-Ink page up for several minutes and the draw will be very minimal. e-ink uses big amounts of power to change the state, but keeping the text on screen takes virtually no battery power.

    As for the allegedly subjective claim..., you are right, there is debate. Based on personal experience, that is my opinion.

    Then there are the disadvantages: page flips are slow and clumsy, artwork is terrible unless it's line art, there's no color (and the color e-ink prototypes aren't going to cut it, either), there's essentially no interaction other than scrolling, it has limited/no multimedia capabilities, and it is, in the words of Alton Brown, a unitasker of the first degree.

    As I said. Some will want everything and the kitchen sink, and others will want a good book reading device.

    Compare a tablet, with a full range of information, Internet, multimedia, gaming, productivity, communication, and reading applications. Tablets done right have screens with good color, viewing angles, and contrast, and highly responsive multitouch interfaces. Battery life north of 10 hours is enough so as to make no difference to most people--they can use it all day, drop it into a charger at night, and use it all day again. The reading applications aren't limited to text, but fully-featured magazines, comic books, illustrated texts, and interactive content, all of which can be used without an external light source with a simple adjustment of background brightness.

    Which appeals to some people and not others. A lot of people would enjoy the benefits. If I had infinite resources, I'd get some very nice (and expensive) technology, and my computer would have top of the line components.

    People who complain about "headaches" when using an LCD are just doing so in an environment with insufficient ambient light, which e-readers only avoid because they're illegible without sufficient ambient light. Whining about staring into a "lightbulb" is only based on poor ergonomic choices that they've made themselves. There is no physical difference to the eye whether light is backlit or reflected; turn on a lamp and/or adjust your brightness in low-light conditions and your problems are magically solved.

    True, to some degree. I would still prefer to read E-ink for hours over a regular display, even with a large amount of ambient light (either from bulbs or natural).

    That said, personal preference is personal preference. If e-ink is the fairy dust cure-all, then it counts against tablets. Does it count enough to give up all the other functionality? That depends on what you're buying it for. But there's little question that
