  1. Re:Fast? on Irrlicht - Fast Realtime 3D Engine · · Score: 1

    They also state in the demonstration program that the software renderer would not be fast enough to run the demo and thus is disabled. I dispute that. A software renderer should be fast enough to do what that demo does considering the world detail. Also, one of the features of the software renderer is that it has a z-buffer. I wouldn't say that this is a feature, it's more of a necessity.

  2. Fast? on Irrlicht - Fast Realtime 3D Engine · · Score: 1

    I tried the demonstation program. It runs at 75fps until the female runner and jumper are displayed, then it drops down to around 35. Curiously, the character meshes seem to be antialiased and run at 10fps, when the world is not antialiased and runs at about 30-40 FPS when the characters are displayed.

    There are stencil buffer bugs when the shadows of the character meshes are hidden behind a partical effect such as the flames.

    I would not call this engine "fast" from the demo. Sure, the flyby ran at 75fps but the world geometry was extremely simple, and I would have expected at least 70-100fps from that without vsync enabled. I can imagine that when character meshes and moving brushes are added this thing will crawl. I imagine this is because they strive for cross-platform portability on the processor side of things and thus (I'm guessing) there's no optimizations (MMX/SSE/SSE2 assembler etc) in the matrix transforms. Someone may want to correct me on that one since I havent looked at the source.

    A good try, but Just Another 3D Engine for now.

    Material to be "stolen", eh? Nobody's stealing stuff from me if I offer it up online for them to take. Makes as much sense as "Officer, my house was burgled after I swung open the door and yelled 'please burgle my house'". It's only indirect theft from the record companies as well. If I broke into someone's flat and pinched all their CDs, I wouldn't be stealing from the record company, I'd be stealing from whoever I just robbed. I wouldn't be making any money from the action either, so it's not like the record company is watching money that should go to them go somewhere else, all they're watching is money not go anywhere at all, and they don't like that.

    Music has to come from somewhere. Currently it's coming out of record companies, who are consistently saying "how the hell do we create an audio track that people can listen to without being able to copy it". This is a pipedream. If you can listen to it and it's on a shiney disc, it MUST go through a DAC at some stage, and that's where your entry point as a copier is. Even with a decent analog system you can make a perfectly fine copy just off the line out.

    If you download a copy of something, rest assured that at least someone somewhere must have bought it. Perhaps now the best thing for the record companies to do is auction off one single original copy of an album with bidding starting at six million dollars, wait for a community of fans to get the funds together and buy it, then watch it spread across the net, safe in the knowledge that they got a guaranteed six million dollars from an album before anyone had even heard it.

  8. Hahaha, open drivers on The Linux Incompatibility List · · Score: 2, Insightful

    Many hardware manufacturers will simply not provide open source drivers for their products, mainly for marketing reasons. Imagine you're a video card manufacturer. You realise people are overclocking your previous line of cards instead of buying the new faster range of cards. So you try to disable overclocking in the driver (presumably by making the driver reclock the card to the correct frequencies, thus undoing the work of any overclocking software). If you release open source drivers, it'd be pretty easy for hacked drivers to be released that allow people to overclock, even though you dont want them to.

    I think the precise reason that OEMs are releasing closed source drivers for Linux is so that they can get in before someone tries to reverse engineer their hardware and pass off some shoddy drivers that cast their hardware or their development team in a bad light. They want to be sure that people use the original drivers for Linux that they support, not some crazy third party ones. They certainly do not want support requests about drivers that they didn't even develop. Releasing open source drivers creates a lot of questions. How do you distribute the drivers? If someone out there fixes bugs in your driver, what's the procedure for implementing these fixes into the main distribution? What legal rights does anyone who adds fixes to the driver have if their fixes are implemented into the main distribution? Do you pay them or do you just thank them? Will you lay off your own developers once you notice that the community is developing the drivers and not you? Will you become lethargic in your testing of new drivers when you realise that you can release shoddy open source code quickly, and the community will fix it for you?

    From an OEM's perspective, open sourcing drivers is a pain in the ass. It sounds like it'd make the development team feel less secure in their jobs (if there's a bunch of people out there that will do their job for free, why are they still employed?) and less determined to write good code when they can pass the buck to an external community.

    You hit a serious problem when you're a professional company earning money from selling hardware, and then outsource one sector of your company to the community. People like Intel have done this, but have dissociated the Intel brand from the open source project as much as possible and turned it into a kind of "novelty" project like "this is what our guys work on when they go home in the evening!". I think that to a lot of companies, open source is merely a device used to improve the company image, to make them seem more forward thinking and relaxed, and get them some damn good press and the lifelong devotion of a great deal of short-sighted nerds ("These guys make things open source, so I'll buy their products because I support open source, even though they're moneygrabbing assholes in everything else that they do").

    The only drivers regular profit-making companies can support are closed source drivers developed in-house. As soon as you implement the code of other people or allow some random guy you don't know access to your CVS to do a few check-ins, you cannot claim to offer any support for the product whatsoever, because people who have worked on it are not your employees and you are not responsible for anything they do, and are consequently no longer responsible for work done on your own driver, which you would like to be able to legally own, support, endorse and distribute with your product as your own (unless you claim responsibility for all work done on the driver by third parties, which would be incredibly foolish). There are also various laws concerning how companies can may make use of contributions from third parties, and what rights anyone who contributes to a company has. Laws concerning competition may also apply here - once the community develops your driver and effectively does work for free that you'd normally pay people to do, isn't that a seriously unfair advantage? Can you give an example of any company that ha

  11. Yet another misguided attempt on Linux Desktop Guide · · Score: 1

    OK, so here we have yet another manual on how to use a desktop. How do I surf web?! Double click Mozilla icon! If you're having difficulties remembering that Mozilla is a web browser, rename the icon "WEB BROWSER".

    Linux is "ready for the desktop", it's been ready for years. What it isn't ready for is typical desktop users. The various linux desktops out there are very nice and accommodate most of the stuff that typical desktop users would want to do. However, where Linux fails the typical desktop user is on three key points:

    Software/Driver installation
    Software/Driver deinstallation and/or upgrade
    Troubleshooting

    Now, before I get the misconceptions brigade sticking their placards up my bottom, I should point out that there are some great tools to help you install and de-install applications on Linux. A lot of them are unfortunately based around RPM, which is a pretty dreadful package format at best. Users need to adopt a new mindset when installing things on Linux.

    Firstly, there's problems in the community, especially with with Linux app websites and naming things. "Binary". What is a binary? It sure isn't an executable file. A JPEG is a binary. This will confuse users who have no idea what a binary is. Binary packages should be renamed "Installation packages", and directed at users (i.e. they should be offered first, the source distribution should be offered in a developer section of a site).

    Second, it's with dependencies. What is a dependency? Why does this application I just downloaded complain that I don't have some seemingly unrelated application installed? "Well that's because the seemingly unrelated application provides shared object files that your application needs. You could try and download the statically linke---" AARGH. Distribute the shared objects required along with your installation packages. If they're already in the system, your installer should detect this and not update system files (like Windows does). Dependencies are the number one reason that installing stuff on Linux can be a real pain.

    Another thing wrong is what happens when stuff goes wrong. Who do you call? Usually your mate who knows a bit about this Linux thing and can fix it up for you. Failing that, you go to an internet café and trawl through endless forums and howto's, which you probably won't be able to find, let alone make sense of, being a typical desktop user.

    You want to install drivers for something? Forget it. This sometimes even involves recompiling your OS kernel in extreme situations. Rarely will an installer be happy to help you with the installation process for drivers. You're expected to know how, and you're expected to read and understand the terminology used in the INSTALL file which is normally something along the lines of "we used automake, so it's the standard process for that, configure, make, make install". To which the end user says "what?!".

    Most Linux advocates instantly seem to shrug off the idea that a user would want to do something as technical as installing the drivers for the new scanner they just bought at Walmart.

    The above problems are not the fault of Linux, but of the state of the community. For Linux to become more user friendly, the community needs to become more user friendly. Mozilla's website is a good example of something heading in the right direction, with friendly icons and simple instructions. However, most other software sites are lagging behind.

    Linux needs to standardize installation and setup procedures between distros to make the process of installing and setting up each application familiar.

    The problem is that Linux started out as a hackers OS, whereas Win32 started out as MS-DOS: an idiot's OS. DOS was simple. Underpowered, yes, badly written, yes, but simple. Windows has always tried to build on simplicity (and it has pretty much failed but what the hell). Linux has to somehow dumb down most of it's doctrines for end users. Simplifying downwards is a lot

    That's bullshit. The echo is simply a reflection from the receiver's end of the call, and happens if they have a shitty phone or phone line. They get crosstalk from the earpiece into the mic. Normally it's not noticeable on landline-to-landline calls because the transport of audio is pretty much instantaneous, but on the cell network buffering, compression overhead and switching all play a part in delaying the audio a bit. This is why you hear an echo. Why would wiretapping cause an echo?

After all, you can always rip the track by playing it on a CD player with SP-DIF output, or even record it over an analogue connection. The protection is there to make ripping more difficult. They freely admit that if you can listen to it, then you can copy it. Any audio on a CD must go through a simple DAC at some point so you can hear it, and that point is the point where you can rip it in full fidelity (if at realtime speeds).

Copying a SafeDisced game takes hours in raw mode, as exactly duplicating the ECC/EDC data on the disc is a painfully slow process (probably because ECC/EDC checking has to be done in software for every block when it's disabled on the drive).

Other software remains legal because it sells itself on the fact you can create exact clones of any CD for back up purposes: not just games.

    It's not this kind of software they should be going after anyway. People don't copy games onto another CD anymore. People create images of a game and distribute it over the internet. It's considerably easier to create an image file, and from what I can tell GameXCopy doesn't let you do this. Furthermore, software such as Daemon Tools, Alcohol 120% and Virtual CloneDVD will let you mount ripped protected images in Windows as if they were a CD-ROM drive. Just download and mount.
