    Actually this is a Powered Paraglider attached to a 4-wheeled cart that can be certified as a 'car'.

    This isn't really a 'new' thing as the carts used by powered paragliders have been getting more and more complex each year I see them, now they are complex enough to qualify as a car.

    That being said, this is awesome!

    360 DVD is only 12x on single layer DVDs (how many games come on single layer DVD, answer: just 4), for everything else, it's 8x.

    360 is also CAV, so it's only 8x at the very edge of the disc, everywhere else it's all downhill from there.

    2x BD is 71Mbit/Sec constant across the entire disk surface.

    8x DVD is 86.4Mbit/sec only on the outer edge, and then peak transfer speed.

    From a different AC Post

    We aren't talking a huge difference in speed (single layer outer edge 360 VS PS3 BR) therefore we must be talking about a huge difference in the amount of data.

    I'll say to you what I'll say to the guy below - if this were the case, then why do 360 games typically have similar or shorter loading times as their PS3 counterparts?

    The amount of data (Duh). The 360 is loading smaller/more heavily compressed textures, the PS3 not so much.

    Why do (certain) PS3 games NEED to be installed?

    Pulling from the HD is faster than from the BR drive, so they install on the HD what they need quickly and keep on the BR what they can spend some time loading

    I've been hearing about some of the newer games going to a "progressive install" kind of methodology, initial install is small, but as the game progresses it continues to copy stuff from the BR to the HD.

  7. Re:WOW on MacBook's "Unremovable" Battery Easy To Remove · · Score: 2, Insightful

    I would understand if there something to gain by not having a removable battery. But really, does it save any space at all? Usually the bottom of the battery is the exterior of the laptop, so it doesn't have to fit "inside."

    That's been covered before, by making the battery completely internal they save enough space to increase the battery size by 40%, this is because of all the casings/latches/power connectors/etc required not only for the battery itself but also to separate the inside of the computer from the battery compartment. This allows them to provide a 17-inch powerhouse laptop with 8 hour battery life, something you only find in netbooks nowdays.

    I know better analogies exist, but I'm not so sure this one is 'wretched'.

    Constellations are nothing more than a pattern overlay on physical objects in order to make sense of chaos. Constellations don't actually exist. The stars themselves exist and can be pointed to, but you have to use your imagination to see the pattern of stars that make up a constellation.

    In the same way God cannot be physically pointed to, instead He makes his presence known through other means, through patterns in chaos. People looking through history (either global, national, or personal) can find patterns that show either an intelligence manipulating the events or an incredible string of luck and coincidence.

    Unfortunately all that is filtered by each person as they look at it. There are many things family, close friends, and even I have experienced that to us are signs of God, that you may just see as coincidence and luck, even though things are so precise. An example from personal experience: we didn't have enough money to pay a bill, one of our friends who didn't know anything about our financial situation sent us a check for the exact amount needed, down to the penny. We see the evidence of God, you would see Luck.

    I am not trying to 'convert' or convince you, just stating what I believe and why.

    Is it possible that I have a personal bias against iTunes? Yes. Yes it is. No Linux support (Amazon runs fine on it), a bloated program that makes me install QuickTime, it reindexes, doesn't let me transfer songs on iPods, wastes CPU, installs a Windows Service, etc. I could go on for hours. And then a family member calls me wondering why her computer runs so damned slow and why she can't have 1000+ songs in iTunes.

    Some of these I can see, especially the windows service, but some of those items don't really work:

    • Reindexing of music is an Option in the Preferences, and is available on other music players as well
    • Quicktime is needed because iTunes uses it for video playback (music videos, movie rentals, etc)
    • iTunes supports more than 1000 songs (I currently have over 6000 songs and over 500 videos in iTunes and synced to my iPod).
    • Not allowing you to transfer songs back from your iPod is a simple measure to satisfy music cartels who worry about piracy, it's done by (queue spooky music) HIDING THE DIRECTORY!!! (oh noes!!)

    I did use them a lot for a while, but I started running out of interesting music and I found out that they don't have rollover (which really sucks getting that last one or two tracks for the month). Also when they upped the price I decided it was enough, while there are some great bands out there, eMusic also has a Ton of crap as well... just cuz a band is an Indie band doesn't make it a good band, or even a decent band...

    After dropping eMusic I went back to CD purchases (used) and a couple albums from iTunes (9.99 per album much nicer then even WalMart's $13 and $15 for most CD's). Mostly it's been single tracks from iTunes, and it'll probably stay that way for most of my music purchases.

  22. Re:Perfection Has a Price on More Than Coding Errors Behind Bad Software · · Score: 1

    Check out nonsequitor's post, that level of testing is expected for Level C, Level B and Level A certification are even more stringent.

    As for what we are hoping to find with all that testing, we have to be sure the software fails as defined (pass and fail actions are defined in requirements as well) and doesn't do a hard crash. There can be lots of funky things going on inside the function that we may not know about, all we know is what it's supposed to accept and what it's supposed to reject. Edge cases are checked heavily to make sure they are coded correctly, limits of the data type to make sure there isn't any weirdness going on there, then toss in a few extra values just for random testing (middle values for pass and fail).

    Between defining data types, pointer arithmetic, and working in confined memory/hardware requirements the code involved can get very squirely in unexpected places, and what you don't want in a 747 at 40,000 ft is an important bit of the controls going squirrely!

  23. Re:Perfection Has a Price on More Than Coding Errors Behind Bad Software · · Score: 3, Informative

    I work at a company that tests aircraft instruments to FAA regs (DO-178b) and I know exactly what you are talking about, but for different reasons. What we are working on basically amounts to full computers (one project even used the PowerPC G5 processor, Alphanumeric keypad, and 3-color LCD Screen), but because of where they are failures and bugs are not an option (for software that qualifies as DO-178b Level A, if it fails there is a very high probability that people will die).

    The testing that we do for hardware and software is way beyond any other industry I've heard of (before reading your post) and took me a bit to get used to.

    For those of you interested, we do Requirements base testing, all the functionality of a product is covered by requirements detailing exactly what it will and will not do. Once the development is underway we are brought in as testers and we write and execute tests that cover all the possibilities for each requirement. An example is a requirement that states: "Function A will accept a value between 5 and 20". This simple statement results in a ton of testing:

    Value In range and Value out-of-range is tested:

    • Test #1: value = 11
    • Test #2: value = 45

    Boundry conditions are tested:

    • Test #3: value = 4
    • Test #4: value = 5
    • Test #5: value = 6
    • Test #6: value = 19
    • Test #7: value = 20
    • Test #8: value = 21

    Limits of Value Type is tested (assuming unsigned short):

    • Test #9: value = 0
    • Test #10: value = 255

    So 10 tests from a simple statement. Once all tests are written we do "Structural Coverage" tests, we instrument the code and run all the tests we've written and make sure that every line of code is covered in a test.

    Only once all that passes is that instrument considered ready to go, that takes a LOT of man-hours to do, even in situations where we can script the running of the tests (some situations are 'black box' testing where we just get the instrument itself and have to manually push the buttons to run any tests... takes a Long time!)

    This level of testing is making me take a second look at some of the software I've written before starting this job and wincing... spending a few quick min playing around with a few different values really doesn't cut it for testing anymore in my eyes...
