    Leave out one key piece of information and it takes on a life of it's own, but there is nothing untrue about the above.

    Conspiracies seem to live on the interpretation that those who believe them have a better understanding of the issue at hand than those in charge, or that they have all the relevant information, when they don't.

    Nonsense. Even if you have all the evidence in plain view there can still be vast networks of shady dealings and huge cover-ups at work. Just look at the Kennedy Assassination!

    Those bones matched royal DNA because they weren't from King Richard III, they were really from a current member of the royal family who has now been replaced with an evil doppleganger clone (made possible by recently discovered Nazi stem cell research and advanced eugenics). They just needed a convenient way to dismiss the evidence -- Oh, that body with royal DNA? Uh, oh, It's just the remains of King Richard! Which one? Why, the 3rd one! Now they've got an inside agent in the royal family... Hot on the heels of Kim Jong Un's replacement of Kim Jong Il, all while for the 1st time ever the USA presidency is held by a black man!?

    Not gonna happen until the FOSS driver built from sources like these shows itself to be competitive in performance with nVidia's closed Linux drivers on comparable hardware.

    Please explain how NVIDIA open sourcing it's closed Linux driver would cause it to run worse? Considering that when the driver is compiled by NVIDIA for a generic architecture versus the same sources compiled by the end users, but able to take advantage of architecture specific optimizations would actually make the open source driver faster.

    At the end of the day we need all the sources for all our hardware drivers so that when the next version of an operating system comes out we can re-compile the driver for the new OS. This is true on Windows, Linux, Mac, OS/2 Wap, whatever. I don't buy drivers, I buy hardware. As someone who can and sometimes does read and write programs in their native machine code forms, the damn driver software is already "open" to me. It would just make it easier for me to make modifications if I had the original sources. Not having the sources does nothing but make me less likely to purchase the hardware.

  3. Re:Dosbox or freedos on Life After MS-DOS: FreeDOS Keeps On Kicking · · Score: 5, Informative

    As a developer, I can say no, that "problem" was just a dumb way to do physics, and it's been fixed forever to anyone who wasn't a moron, even in the AT/XT days. Back in the day we just checked wall clock time / CMOS ticks, you know, the ones we used to modulate PC speakers to make different frequencies, that's what we used to update game state and prevent binding physics to CPU speed. Today, RAM is plentiful, so I do physics state "commits" in fixed step sizes, say 30hz or 60hz, and interpolate from the last physics state to the temporary state that's being rendered.

    If enough time has passed to process the next full physics step, then it's processed and committed. Otherwise I reset state to last commit, and process the partial physics step, but do not trigger any important events like player death in the temp step. If the system is too slow to run a partial physics step without immediately requiring another full physics step then the partial steps are not processed and the game rendering updates screen positions only after the physics step can be computed. This is important for deterministic physics, for demo replay and also for synchronized network games because:
    UpdatePhysics( 20ms ); UpdatePhysics( 20ms );
    is not always equivalent to:
    UpdatePhysics( 40ms );
    Due to a number of factors, especially rounding errors.
    UpdatePhysics( elapsedTime );
    Is the worst on fast systems -- those very small fractions of time lead to physics explosions -- not the particle effect kind, the bounce off an object through the floor and to the other side of the universe kind.

    For comparison:
    Here is my rope physics with a fixed physics step size frames.
    Here is the same physics running with actual elapsed time each frame.
    The latter comments mention tiny jiggles propagating into a frenzy. Those tiny movements coupled with very small elapsed times create the physics explosion.

    So, your answer is that because google has decided it has the right to redistribute copyrighted images in full resolution in most cases, that everyone else on the web should go to Google and opt out of their caching system? Site owners are in coorperation with google, we like google when they don't do fucked up illegal things... We see thumbnails as "fair use", maybe. We don't mind much as long as the users end up on our site to see the image. Google understands advert revenue funded websites... They are one. So, it's really hard to understand users who want free stuff saying that we have to change our business practices, and maybe not even give them free stuff (or make it harder to find free stuff) simply because a bigger free stuff provider decides they can get away with infringing copyrights of everyone.

    Your solution is not a solution. A real solution will be to address the issues. Hell, maybe while google is processing the images to reduce their resolution and run heuristic matching algorithms for their other-sizes and search terms feature, they can water-mark them with the domain name of the site they downloaded the image from.

  6. OUYA: Free To Play PITA. on OUYA Android Game Console Available In June · · Score: 5, Interesting

    IMO, everyone misses the biggest deal with the OUYA: Its payment API stinks.

    In the OUYA developer API: All programs must be down-loadable for free. There's no option to charge for the game first. There's no option to have a free version and a paid version -- It's got to be an in-app purchase if you want that, it's more complex and harder to get right, esp. from a security standpoint, esp. when trying NOT to annoy your customers. The payment API has re-occurring subscription payments, it has replenish-able items that can be bought multiple times (think Zynga Energy Bars, or game currency), and it has one time purchasable items (like unlockables). This means I just say NO to OUYA.

    This means developers who just want to sell you the whole game once and you have it and that's it, really only have one option: Game Demo -> Try Out -> Purchase Rest of Game -> Wait for it to download the rest of the game. Otherwise, OUYA games really will be the most hackable: Download full game -> It's got locked features -> Run the keygen / crack. -> You've got the full game -- I wonder what the Venn diagram looks like for people to which a $100 console price point is compelling vs people who've ever ran a game keygen / crack... I bet it it looks pretty much like a single circle.

    I've done research on the try-before-you buy "game demo" method in my own apps. What happens is that players impulsively download the games. Some forget about them, then delete them without ever playing the games. Most play the game first, feel their curiosity is mostly satisfied, then they forget about it and delete it later. A rare few will download the game, play the demo, then after that impulse has passed, return to the game and buy the "next episode" or "full game".

    So folks like me who actually love making and playing games, and have no interest in being nickel and dimed to death or doing so to our customers see the OUYA as a non-starter. Less Choice Is Bad. OUYA gives devs LESS CHOICE about how to sell their game, they're betting big on the Free to Play (read: Pay to Win) model that I will never buy into. There's some controversy over whether or not game demos actually hurt sales, so IMO it's foolish to leave no option other than to have game demos, or free to play. Additionally, I've done all the research I need. I've seen our sales numbers much lower for apps released with trials vs those without trials. A better method is to not do trials and simply reduce price slowly until you discover the impulse buy amount.

    The OUYA dev platform didn't have all the payment and registration services even working to test games against when I checked a couple of weeks ago. As a developer: Screw OUYA. I'll release some of my 100% free games there if I remember. This console has "cheap" selling point that targets people opposite to the ones that will actually buy the games. The folks that have disposable income are the ones who unlock the full game after playing the demo. They're the ones that spend $60 on "energy" to get some in-game artificial delay, rather than the poorer sap who'll grind away tons of time to achieve the same. Protip: these non-in-game purchasing grinders are the bigger fans; The grinders will buy the next game, or nearly anything new you ever make -- esp. if it's not free-to play.

    I'm not seeing WHY people will buy the OUYA (other than all the damn hype). Having a portable game system (smartphone / tablet) that can optionally hook up to the TV and use wireless gamepads, or having a portable game system / tablet and also spending an additional $100 non portable OUYA that you must hook up to your TV, uses a gamepad, and doesn't run all the games your smartphone / tablet will.

    Who knows, I'm sure if I hired a patent attorney they could write up patent claims vague enough and using terms obscure enough that a patent clerk wouldn't find any relevant hits in the patent database, so there's really no reason to assume that the INI file format isn't pattented... but if it's not, then they can piss right off.

    He's not re-distributing their files, so he's not infringing copyright. The name winapp2.ini is too generic to be a strong trademark, except maybe to Microsoft over Windows (tm).

    I wouldn't worry about shit. In fact, I wouldn't have even acknowledged that I received a notice of any kind.

    Protip: In the future if you want to incorporate a 3rd party's data format, implement a plugin system and API for importing the generic data to isolate the main application from the import functionality. Distribute the plugin that implements the import feature separately, it can download after install at the behest of the user. Defer all complaints about plugin functionality to the "owner" of the plugin -- A different entity than the one that holds the rights for the main application. I call that a firewall.

    I suppose INI itself may be so generic as to not really qualify as supporting another program's data format, but even so it would be pretty simple to make a .INI translator program that simply search and replaced the [SECTION] tags with differently named tags, and distribute a converter that converts their format into your format prior to import. I really wish SCOTUS would do something about data formats: No one should be able to assert rights over something ilke .WAD, .JAR, .INI, CSV, XML ugh, Microsoft was sued over using XML.. So, I think the only way to achieve that is to say all file formats are public domain. Good luck with that.

    Then again, IANAL. However, I've been through this shit several times. There's nothing you can actually do at all to avoid being sued. Anyone can sue for fucking anything, why worry about it?

Yep, brand now company buys an LLC shell to operate under and adopts its good standing credit, and incorporation date.

For instance, if it's not a big deal to give children, drugs in caffeinated beverages, then why the big deal about other recreational or performance enhancing drugs for adults?

This "widely varied effects" phenomenon is typical of nearly all drugs. Our bodies and minds are very complex electrochemical machines, to properly regulate the intake of drugs we should note their effects on the individual itself -- If we can't come up with at least a fairly accurate mapping of intake to caused behavioral changes, then we should let the individuals decide for themselves, and test their abilities in order to determine if they're too drunk, too wired on caffeine, or too stoned to operate a vehicle or be presentable in public.

    Seems fairly stupid to arrest people for having a few beers and driving when we don't even record statistics for comparison of the other drug users amped up on Starbucks and Adderall, taking corners and weaving through traffic like madmen.

These console specs are already shittier than a budget PC build I did for $500 today. When they're released a similar spec'd PC might be $300 or less, or even doable in a laptop. With a PC you can add on another GPU via Crossfire/SLI or hell even just more RAM for a relatively cheap and simple upgrade path -- Just ensure the PSU is big enough from the outset. Hell, AMD APUs eliminate huge RAM to GPU memory bandwidth burdens, and have "dual graphics" tech where you don't have to disable onboard GPU, it can assist the discrete GPU like crossfire, giving a really cheap upgrade path.
