  1. USe this program from this website below...http://www.derlien.com/ This graphical utility will show you what is using up all your hard drive space. Then you can just delete the files you dont need that are taking up space.
  2. This is funny. Their is a full translation in this spoiler box bellow
  3. Alright I will try to answer some of your questions. Right now, most OS use drivers to work at a kernel level, OSX, Windows, and Linux. However Linux and OSX support user space drivers. Also OSX and Linux are Unix based so Ill explain why that matters in the end... Yes, it is far more compilcated then you are making it out to be. You see, vendor ids mearly exist so the computer software can reconize the hardware. How do you think the software knows you have a logitech xxxx mouse, instead of just a Mouse. The vendor id does not contain any software it is just used to identify the device. Mac OSX is optimized for computers using an efi capable motherboard with apples firmware, with the PPC or AMD64 (intel core 2 duo) architecture, and using dual channel ram. As long as your using Apple Hardware their will be no change in efficiency and you generally will not have any problems upgrading hardware that is not a graphics card. Also Mac OSX works best on Apple hardware that has matching ram cards in each slot. That way dual channel ram can be utilized. This is also why apple only sells ram in even numbers (2gb, 4gb, 6gb, 8gb, 16gb, 32gb). When you are running OSX86 which is on non apple hardware it is going to be slower. This is because pcs made for windows use the bios. This is because Windows Vista Ultimate x64 is the only version of windows that supports efi. Mac OSX only supports efi. So when it is running on a PC made for windows part of the cpu needs to be used to emulate the efi functions. Also most of the hardware does not support dual channel memory, which in turn slows it down. Then you most likely would need to use drivers that were designed for a hobby by the OSX86 community which are often at a lower quality. Windows and Minix uses Microkernels. Linux and BSD use Monolith kernels, Mac OSX uses a hybrid kernel. ll explain the difference later. Their is so much differences in OS's that the hardware rarely even matters any more when comparing performance of similar computers. They all use different windowing systems (xserver, dwm, or Aqua), manage ram differently, manage gpu's differently, different rendering engines, manage cpus differently, hard drives, etc. Now to explain classes. Any certified Unix system (Linux, OSX, BSD, UNIX) uses classes. What this does is assume that you, the user are the biggest security threat to the computer. So by default you do not runs as root (admin) and the system blocks you out of certain specific things. Processes and files are divided among classes using a permission system. An example of this would be. So a system boots up the operating system tells the bios or efi to start the hardware needed for bootup and may run some quick hardware checks, then it finishes loading the kernel, these processes will be under the class "Kernel". Then it will proceed to boot up the system. Once the system is booted those processes would be in the class "System". Then a few daemons and drivers will be loaded as "root". The login screen will pop up at this point. Here the user lets call them "User 1" and say they have admin rights to the computer. They will login with their user name and password. Here any processes they start will be under the class "User 1". So User 2 logs in. Starts some processes. These will be under the class "User 2". Will say that User 2 is non admin. User 1 will only have access to his/hers home directory, a public folder, user space drivers and maybe the applications folder. When he/she needs to access something in one of the other folder he/she is not allowed in it will report a permission denied error. To do this the user would need to go into root mode by entering their login info again. This will give them "User 1 root" which will allow them to modify files labeled under System or Kernel. How ever unless User 2's settings allow it User 1 can not modify User 2's files. To make it even more secure each program is sand-boxed from each other. So this helps with security and prevents viri. this is how. So User 1 visits a malicious page in firefox. it downloads a small daemon, and trys to install it, it will get a permissions denied error. Or, it could hijack firefox. When this happens on windows the system is at the attackers will. On Unix based OS's then the application will only have access to the files that the application "firefox" has permission to access. So lets do an example of a trojan then. The idea is that when the user downloads the application on (mac osx) the user would wonder why it needs a password because most things dont need a password or on (linux) the user who would fall for that would not most likely understand how to install something not from the package manager. The difference between a micro kernel, monolithic kernel, and a hybrid kernel. In a micro kernel the device drivers and services are not included in the kernel. In a monolithic kernel they are. In a hybrid kernel most drivers and services are included with the kernel, but some are not. Hope this helps.
  4. Thanks, I am trying to learn webdesign so I dont have to keep on asking so can you tell me how this code works (whats happening, etc)? sorry for being difficult.
  5. This was the first method I tried, However the gradients looked awful in a gif image and messed up the glowing effect...
  6. I am working on my website, and needed some help with javascript. My website that is in progress is located at http://www.110mb.com/404.php Anyways, here is what I would like to do. I want to have the navigation bar fade to the second image instead of changing instantly when you hover over it. So the color would fade from blue to red when someone hovers over the link. Help and advice would be appreciated. This is my first website so I am sorry if Im a bit of a Noob to this.
  7. I really like this idea because then I will be able to play games on my Macbook, and be able to say. Yes, It can run Crysis, ***** next time someone annoys me asking that. Also I always hated gaming on a PC because of how often you have to upgrade hardware, this fixes that problem. So, I can say that I am really excited about this service.
  8. This already happens. Most hardware has a vendor ID, which can be used basically the same way... The only reason why OSX would trump Linux in hardware efficiency is because its designed specifically for the hardware. While linux is designed to work on most hardware configurations.
  9. What version of Wine and iTunes are you using? I could not seam to get it to install. It would always say "The iTunes installer has encountered an error and all changes to your computer have been undone" or something similar, when it is installing quick time. My parents really like the iTunes store for some reason, I have tried to get them to use Amazon, but I havent cared since the store went drm free and started using 256 bit AAC which pretty much brought it on par with AmazonMP3.
  10. Smash Bros. = THE best arcade styled fighter game ever. I remember having so much fun with the game-cube version. I should try the brawl.
  11. Huh? You can move tabs in it. You just hover over the tab, and move your mouse to the "grab area" with the diagonal lines on the right side of the tab. And then you can move tabs between windows, into separate windows or in different place on that window.
  12. Any suggestions on how to get iTunes working in linux say through wine, crossover, etc. I am going to move my parents over to linux and that is the only app I can not find a viable substitute for.
  13. I have found that xp beats windows seven. I would say that windows seven is about 80% as fast as xp. However windows seven has a much better gui, more features and is more secure. So pick your poison, speedy but less secure, or more secure but slower.
  14. Also the design of the os is to only work on efi intel, or open-firmware powerpc based computers running the apple firmware. When you install it on a PC through OSX86 you are emulating this and wont get nearly as much performance and once again, its illegal and unsupported.
  15. Stanford (yes the colledge) is offering free video lessons on various subjects including programing through itunesU. here is the link http://itunes.stanford.edu/ The lessons here will be beneficial to any level programer. EDIT: Sorry this is in the wrong section. If your a moderator please move it to the Online Education section
  16. Sorry I listed that wrong. Let me explain, Windows has a far lesser learning curve than Linux do to the simple fact that people know how to use it and it is used by 85 percent of people. Also linux is always getting better. I remember when I first tried ubuntu (version 6.04 I think) that was terrible. Then I tried 7.10 and liked it since. So the main reason that I put it below windows is because their is no way that I would be able to troubleshoot a linux problem with someone who is not good with computers, say over the phone.
  17. I am using it right now. However their is a bug that when you have over 1,000 websites cached (sad, I know) using it becomes slow as safari searches the large cache. Oh well its a beta for a reason.
  18. I would suggest using handbrake for your dvd ripping. It is freeware, open source, has a ton of options, and is crossplatform
  19. I use photoshop, illustrator, and pixelmator.
  20. I like coda, I hand code my websites and have found coda very powerful. It has included books and it is cheap.
  21. Wow, This is excellent info. I am glad I looked at it. I am working on designing my homepage right now and this helped alot with design aspects.
  22. What it looks like you are trying to do is set up an ad-hoc network. I could give you a guide if you have a Linux or Macintosh PC in the mix somewhere... but I dont know how to set one up on an only windows network. It would probably be easier for you just to get an ethernet switch or a router.Multi-plicity allows you to control two computers with one mouse and keyboard. It is not what you are looking for...
  23. This thread is almost 5 years old... And on topic I would recommend webkit. It is the source code for safari. And is updated every night with technological advancements. It is THE fastest web browser currently available and meets all web-standards.
  24. Before I get into this just to clear any doubts. THIS IS NOT MADE FROM STEM CELLS, AND NO BABYS WERE HURT. The Zii is a media processor (processor+gpu+decoder+ram) that takes chip design to a new idea. The design was based on research from stem cells. The special design allows the processor to "morph" into the best processor for the job. The processors seem really powerful (each of the chips can control 4 1080p displays showing different video). And they can be linked together to increase their ability. Here is a youtube video showing them making a teraflop computer (1000 gigaflops). http://forums.xisto.com/no_longer_exists/ Their website is http://forums.xisto.com/no_longer_exists/ Seems cool to me. Thoughts?
  25. Do any of you here use Objective C? I am debating about learning Objective C or C++. I was wondering, is Objective C more efficient than C++, or what is the advantages of each. So I can make an educated decision.
