    That kind of virus protection was present in older BIOS implementations, while win9x/ME was still present. With Win2K/XP, no such protections work (for MBR booting) because other drivers are accessing the HW directly (and you cannot enforce on HW because that would prevent repartitioning).
    For UEFI-booting, the UEFI firmware has a complete path to a partition+file. There is no way to protect a single file with a compromised OS.

    My experice comes from Lenovo with Win8 consumer preview.
    Used win7 (from lenovo) and debian, both through UEFI.
    Installed win8 CP over win7. 1st problem: i could no longer change the boot order. I could boot both OSes, but I could not boot linux without boot menu.
    So I used the UEFI tool from debian to change the order.....debian booted by default...but win8 refused to boot.
    No option to disable secure boot.

    So my opinion, MS is to blame only for forcing secure-boot, leading to OEM delivering incomplete implementations.

    I wonder who selected the test music? Like many already commented, some music sounds better than other at same rate of lossy compression. Not to mention the encoder itself.
    Just make sure you listen to one tune from your original CD is a quiet room and then switch to it's mp3. Difference comes from comparison, and if you can't accurately remember one sample while playing the other, you can't make a comparison. Oh...and you can test them with you 2$ earbuds.

    Do remember that any statistics can be skewed to show one result or the other, when infact the truth is right in the middle.

    PS: the article you point to has only a few paragraphs for lossy compression, with no conclusion. Nice read (I already agree that CD-quality is enough)...but....

  6. Re:Better question on Can You Really Hear the Difference Between Lossless, Lossy Audio? · · Score: 1

    Please stop comparing analog reproduction with digital artifacts. Lossy compression brings artifacts. For example take a single note on an instrument which produces a range of frequencies, something like a gauss curve. The lossy compression in this case would just cut the ends of the range. This is related to low-amplitude (low-volume) frequencies. This can be heard even on cheap gear provided the ambient noise is low enough. But the question is: do you actually know how the instrument has to sound?

    If you listen to just mp3s, then ok...you say mp3s are as good as the original. But did you listen to the original as much as the mp3? Did you listen to it in a low-noise ambient (something like goind-to-sleep enviroment)? Even the cheapest gear can show you the artifacts. And once you found them, you will always hear them.
    Ok...maybe I sound like I say that cheap vs. quality equipment makes no difference. That is not true. Reproduction quality does make a difference of how you spot the artifacts, but the idea is that the difference is not that big. I think most artifacts can be spotted in low-ambient noise enviroment, which is usually not associated with cheap equipment. Compact PC speakers? Gaming/office computers (where focus is on the screen, not audio). Earbuds? Portable on the (noisy) street (to exchange enviroment noise with music). Hi-fi gear? Dark, silent HT room.

    As a side note, while many people cannot differentiate lossy vs lossless (or did not have the right enviroment), I noticed very annoing artifacts on recompression: I made a local-network radio station (because I got tired with 3 devices with it's own playlist) with 320Kbps MP3 streaming, and when I got to hear a 128Kbps song, I had to stop it after 10 seconds (I'm talking about rock which some say it's hardest to spot). The original 128Kb song was good enough, but recompressed (even to higher bitrate) was terrible. Now I have 2 streams, one flac for devices that support it, and one 320Kbps mp3 for those that don't or when I want to listen away from home (well, Logitech insists on checking my private streams, so I had to make them available outside). And I avoid mp3 files as much as I can.

    Fine.

    The tablet he describes may appeal to several hundred to several thousand people worldwide [given the current tablet market largely filled by iPad's, Kindle's, and Samsungs].

    And at that price, the market for the device is right about ZERO.

    Actually no...the features he's requesting, except for the offline maps (which is entirely SW solution and I remember the WM5 prices) would not raise the price, let's say of the nexus 7, by more than 100$. So that would be 250 raised to 350....much lower than 1000$(were you start). Remember, the HW design phase is long and costly, but starting with those added goals will not increase the cost per unit very much. The HW cost of components is much larger (especially in todays global economy) than the development.

    I personally love the N7 construction except for the missing card reader and HDMI output. Those were my deal-breakers. But just because someone bought it and never complained, does not mean he/she would not have paid 50$+ to get those features. And if you say they'd never use them, you'd be surprised of the difference between requirement and usefullness (what was that quote: better to have, and not need, than to need, and not have). I'm sure N7's sales would not have been affected by +50$ for those 2 features, since it had virtualy no competition at it's price (maybe Galaxy Tab 2, but that require you to carry proprietary adapters).

    You want a standard for controlling, so that everyone can control their aid, but that also opens the door to those that want to control OTHERS aid, without their permission. Sometimes the standards have holes in design, other times the implementation can have bugs. Either way, it's a risk no medical company will take. They prefer a closed protocol, that can not go through external scrutiny (security by obscurity).
    Another such example (in my line of work) is usage of ethernet in cars. While ethernet by itself would be ok, they also want internet in cars, which means there will be at least 1 device with both connections (internet and in-car ethernet) which will be vulnerable to external attacks (think about someone locking your brakes at 100mph, after disabling ABS+ESP).

    Actually the problem is real. And I'm not talking about MS, but BIOS (should I say firmware) vendors. I played with my Thinkpad Edge E120, and I found a problem: after installing Windows 8 (consumer preview...as I remember), I could no longer change the boot order from the setup screen. One-time boot choice does work, but I could not change the order for permanent usage.
    Also, as soon as I changed the order from linux, Win8 refused to load (even after returning the order to the original one).
    My thinkpad has no mention of disabling secure-boot. I don't even know if returning to BIOS-style booting would allow me to change the order.

    I've got nothing against secure-boot, but easy methods of self-signing need to be provided. The secure-boot should be "binaries that I trust", not "binaries that MS trusts". The latter is fine for most end-users, but those who do know what they do....should not be locked by vendors.

    So I would say boicott vendors to support secure-boot better.

    PS: no I don't know the API details. I did see articles stating bad reference implementation of UEFI. And I mean really bad (as in inability to follow the specification 100% to boot something).
    PPS: while this post may seem to be defending MS, I can guarantee that I want to dispose of it in my daily use. I even went so far as to virtualize a Win7 enviroment specifically for gaming (with AMD 5850 that is...... thank you Xen comunity + Intel VT-d).

    What the fuck does that have to do with anything? A kid in a basement could develop a new hardware design as well. Or invent a new mousetrap, which would be patentable. But in the end, the cost and complexity of the equipment used to manufacture an invention have absolutely jack shit to do with the patentability of that invention.

    Sure it does. Patents provide you with control over your idea and offer a monopoly to it's implementation. If you don't license your idea (which is legal), you can only obtain money if you sell end products. Those end products have high margins for SW, where you can have 90% profit easy (note: not the research and development, only manufacturing=copying), whereas a HW product will probably not have more than 50%. Also, for SW you can sell at least 10x the number of units compared to HW, since the replication of HW will take you a lot of time (let's face it, a basement kid will not have a production line). So this rough computation means you get at least 18x money in the same period. Also, the investment (R&D) is much lower in SW because testing is done much faster and cheaper than a HW product. Why do you think almost everything goes into SW?

    As for the process comparison, many SW patents are actually too small modules. Companies are not interested in quality patents, just in numbers. They throw patents hoping that 10% are approved. For instance Apple's "slide to unlock" patent I would compare it to "low-pass filter". Surely nobody used it until iPhone, but they were not many touchscreens at that time (PDAs and tablets were limited to business users). So while Apple did show the idea, it was approved too late (because of the delay in millions of other SW patents pending) and now is common because of their marketshare in the category they created.

    In summary, you have much bigger profit and faster time to delivery, but you still get the HW's exclusiveness period. This is just milking the system and NOT supporting innovation. Supporting innovation is allowing your competitor to improve your idea if you cannot or, just the fact that he can improve, to offer you an incentive to improve it first. If your idea does not catch immediately, then you are in the wrong time and deal with it: innovate more. If it does, then learn to profit in the shortest time but still innovate while in peak, don't turn into a potato-couch for the rest of your life.
