Help for a MS Windows programmer- Unix

I havent used Unix in ages. Ive since been programming with VB and all the MS-related ballyhoo. Ive done some Java programming in the past, back in the JDK1.1 days. In the last few months ive been digging deep into J2EE as well as Swing. However, all of this development ive been doing has been on NT and Win2K. I need to learn/relearn Unix. Where/how do i start ? Im thinking that i should just load Redhat linux on an old machine i have and have at it. any ideas appreciated.
mtndood out

Try this link:

for a free online Unix tutorial. I think loading Linux on an old machine is an excelent idea.

  • Help for all frustrated windows itune 5 downloaders

    I recently downloaded itunes 5 and couldn't open it even though the download was successful. I messed around for hours getting very frustrated to try and make it work. I eventually found that by turning my Norton antivirus firewall off and turning on my windows firewall instead, I could open itunes! I don't know if it is just norton antivirus that affects itunes so others might too. Hope this is helpful!

    Sorry, Bill, but there is no way to run iTunes under Windows 98. For just synchronizing tracks with your iPod, you could get a third-party utility such as Anapod, Ephpod, or Xplay for handling the transfer. I haven't used any of these, so I can't make any recommendations. Note that these applications cannot purchase tracks from the iTunes Music Store which is only possible through iTunes.
    I strongly suggest you consider upgrading your version of Windows, though. Windows 98 is no longer supported by Microsoft and it's going to get harder and harder to find applications that will work under 95/98/ME.
    Hope this helps.

  • Newbee help for dicom image window center/width manipultation

    We have a flash based dicom viewer and i have the folowing code in action script which i want to replace with pixel bender code. is it possible ?
    var img_bmp:BitmapData = new BitmapData(Cols, Rows,false,0);
    for (var y:Number = 0; y <Rows; y++) {
    for (var x:Number = 0; x <Cols; x++) {
    gray =  byteArray.readUnsignedShort()*Slope + Intercept;
    gray = 255 * gray/WindowWidth  -  Min * 255 / WindowWidth;
    gray = uint(gray);
    var r:int = gray;
    var g:int = gray;
    var blue:int = gray;
    var c:uint = (r << 16) | (g << 8) | blue;
        img_bmp.setPixel(x, y, c);
    Where byteArray is a unsignedshort  sequnce. Slope, intercept, WindowWidth and Min are constants.
    From the little i understood of the kernel programming the expected input channel cannot be 2 channel or single channel input.
    can any one suggest how i can proceed or give me pointers or for this kind of image manipulation pixel bender is not suitable.
    Thanks in advance

    can some one tell me how to get the shader width and height so so that pixel bender can only act on 16 bits or did i get the whole thing wrong.

  • Ora-25215 from windows to unix - please help

    I have successfully set up streams replication from unix to windows -- it works beautifully!
    However, when I set up streams with a different set of tables going from windows to unix, I get the propagation error, "ora-25215: user_data type and queue type do not match"
    I have been all over metalink and the internet trying to find a solution or explanation, and there is very little out there. I found a dozen hits on my metalink search on ora-25215 and one of them was "How to resolve ora-25215..." Alas, it really doesn't address a fix for simple streams, it goes into setting up a payload, etc...
    Like I said, my unix to windows works like a charm, but unix to windows doesn't. By the way, my windows is 2k and my unix is solaris 8. Anyone have any ideas for what the problem is?
    Thanks,
    jimmy

    Jimmy,
    Make sure your propagation is configured correctly. It is also possible to get this error in Oracle9iR2 if you use the wrong queue name or schema when configuring propagation.

  • Wireless printer sharing- Verizon only has automated help-or any help- for windows. i have a mac.

    i have a new Brother 490CW which instructs me to "push the WiFi protected set up button" on the router. the Verizon supplied router Ultraline series only has on/off power button.  Verizon's help is abysmal.  The automated response sends me back the the help for windows.  can anyone tell me how to set up this printer as wireless?
    thanks.

    Pretty good directions here : http://www.brother-usa.com/support/wireless/Step1.​aspx?ProductID=MFC-490CW
    You'll find the SSID (ESSID) + WEP key on a sticker on the Verizon-supplied router.

  • Creative Zen Micro Photo not tested for use with Windows so cant install it! Please help

    Heya! Basically when installing the software for Microphoto it stops saying that as my device hasn't been tested for use with windows it cant install for fear of corrupting my laptop! Can anyone help me overcome this because i installed it aagges ago and it let me have the option of continuing the installating, but i had 2 uninstall it and upon reinstalling it it does not give me the option to continue. It just cancels the installation. Can someone please help me as this is driving me nuts!! Y is it that technology is continuosly mucking up grrrrr!
    Lucy

    Are you runnning Win XP SP2? If so, this is a standard warning about unsigned drivers, but it should still give you the option to "continue anyway" to complete the installation.
    Also, make sure you have Windows Media Player 0, as this is needed for Windows XP (drivers) to recognize your MicroPhoto.

    Please help :-)
    Thank you for your help.

    Well, generally file paths on unix and windows are very differently arranged, so it's actually fairly unlikely you'd want the same paths. Genarally files are either resources, best accessed with getResource/getResourceAsStream or they ought to be variable, perhaps stored in configuration (it's well worth getting to know java.util.prefs.Preferences).
    And I usually find that if I'm dealing with a directory heirarchy relative to some base directory the two parameter File constructor is cleaner than mucking about with path separators.
