[solved]confused about bootloader to use

I have a uuefi motherboard but in my BIOS drives some say ahci, not sure which bootloader I should use.

If you are comfortable with the old bios way of doing things, then I see no reason why you should force yourself into learning about UEFI if you don't have the desire to do so. Most UEFI boards have a legacy bios mode, so you can continue to use that if you please.
BTW, I use gummiboot, with rEFInd as a backup, and elilo as a backup to the backups (and just in case I have an old kernel w/o efistub). I also have direct firmware boot manager entries for each of my kernels, as well as both version of the UEFI shell as a super duper extra backup. That is one of the advantages of UEFI, you are not forced to use just a single bootloader, as they are stored in the EFI System Partition, which can be as big as you want it, instead of just the first 446 bytes of the disk like bios. This makes the necessity of crazy chainloading unnecessary, which is a real treat.

[SOLVED] Confused about Mobility Radeon HD 3200

I've always found hard to find good information about this card - some sources, even, contradict themselves. All what I know is that it is an integrated graphics card and that it features the RS780M chipset. These are some tips I've got from the system logs:

I also found good (?) information, or at least a clearly-explained article, here. After reading it, UVD appears as the AMD's counterpart of NVIDIA's VDPAU for video acceleration.
What I'm not sure about, is:
- Does it support video acceleration? I'd like to offload video processing to the GPU, but am not sure if my card and the open-source drivers support it or not. Wikipedia's article about VDPAU states it comes from NVIDIA, but then it says it has an open-source implementation.
- What has gallium to do with it? What gallium drivers should I enable in mesa? And what about DRI drivers?
I configured mesa as follows:
./configure --prefix=/usr \
--sysconfdir=/etc \
--with-dri-driverdir=/usr/lib/xorg/modules/dri \
--with-gallium-drivers=r600 \
--with-dri-drivers=radeon \
--with-llvm-shared-libs \
--enable-gallium-llvm \
--enable-egl \
--enable-gallium-egl \
--with-egl-platforms=x11,drm \
--enable-shared-glapi \
--enable-gbm \
--enable-glx-tls \
--enable-dri \
--enable-glx \
--enable-osmesa \
--enable-texture-float \
--enable-xa \
--enable-vdpau
Not sure if I missed something, though.
I am very confused about how Linux manages graphics, and what all those layers are for. DRM, DRI, VDPAU, VA-API, gl, gl3, xv, xvmc... it's a mess!
Thanks in advance.

The feature matrix might help. The easy part to answer is that the 3D driver is split into two parts: DRM which is part of the kernel and DRI which is in userspace and comes from the mesa package.
Xv is an Xserver extension supported by pretty much all drivers. Found in the DDX (xf86-video-*), it uses features of the card to speed up the display of video (but not decoding). It can either do this by using the "video overlay" or creating a shader.
Now if you want to use Xv but also offload decoding to the card, you need a video acceleration API. The ones to choose from are XvMC, VA-API, VDAPU in increasing order of feature support. They were developed by Xorg, Intel, Nvidia respectively but anyone is free to implement them. I don't think it's correct to call UVD a counterpart of VDPAU. UVD is a bunch of registers on newer AMD cards. And if you sent bits to those registers in the right way, you can implement VDPAU.
The other way to implement VDPAU (say if the documentation for UVD registers was not released) is to use gallium. There is a gallium state tracker which can still do it at the expense of being slower. It is a hack whereby you convert video frames to polygon textures and make the OpenGL part of the card think that it's calculating part of a 3D scene when really it's decoding video.

Confused about how to use paint()

Hi, I have been working really hard to try to get the following program to work but I am really confused on how to use paint(). I do not have anyone to ask so I thought this forum could help. Anyways, here is my problem...
I am trying to recursively figure out the Sierpinski fractal. I cannot figure out if my math works or not because I do not know how to call the paint() recursively to draw my triangles.
Please have a look at the following code. Thank you!
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
public class DrawTriangle extends Frame {
Point a = new Point(20,480),
        b = new Point(350,40),
        c = new Point(680,480),
        halfB,
        halfC,
        halfB2,
        halfC2,
        halfC3;
int width;
public DrawTriangle() {
    super("Sierpinski Fractal");
    addWindowListener( new WindowAdapter() {
      public void windowClosing( WindowEvent we ) {
        dispose();
        System.exit( 0 );
    setBackground( Color.white );
    setSize(700, 500);
    setVisible(true);
public void paint(Graphics g, Point a, Point b, Point c) {
    width = c.x - a.x;
    if (width < 6){return;}
    g.setColor( Color.GREEN );
    g.drawPolygon( new int[] { a.x, b.x, c.x }, new int[] { a.y, b.y, c.y }, 3 );
    halfC.x = c.x/2;
    halfC.y = c.y;
    halfB.y = b.y/2;
    halfB.x = b.x;
    halfB2.y = halfB.y + a.y;
    halfB2.x = a.x;
    halfC2.x = halfC.x + a.x;
    halfC2.y = a.y;
    halfC3.x = halfC.x/2 + a.x;
    halfC3.y = halfB2.y;
    paint(g, a, halfC, halfB);
    paint(g, halfC3, halfC, halfB);
    paint(g, halfC2, halfC, halfB);
public static void main(String[] args) {
     new DrawTriangle();

thanks jsalonen, your tip let me start working on the math to correct it.
I have a new problem now. My math is correct but I am having problems with the recursion. I can draw only the top , left , or right triangles. I cannot get them all to work together. See code and comments below.
Any ideas why I cant call all three of the paint()s toegther and have them work?

    halfA = new Point((a.x+b.x)/2, (a.y+b.y)/2);
    halfB = new Point((a.x+c.x)/2, (a.y+c.y)/2);
    halfC = new Point((b.x+c.x)/2, (b.y+c.y)/2);
    g.setColor( Color.GREEN ); //draw left triangle in green
    g.drawPolygon( new int[] { a.x, halfA.x, halfB.x }, new int[] { a.y, halfA.y, halfB.y }, 3 );
    g.setColor( Color.RED ); //draw top triangle in red
    g.drawPolygon( new int[] { b.x, halfA.x, halfC.x }, new int[] { b.y, halfA.y, halfC.y }, 3 );
    g.setColor( Color.BLUE ); //draw right triangle in blue
    g.drawPolygon( new int[] { c.x, halfB.x, halfC.x }, new int[] { c.y, halfB.y, halfC.y }, 3 );
    /*If you were to comment our two of these paint() calls the one will work correctly alone.
     *But my problem is that they do not work together! */
    //g, left point, top point, right point
    paint(g, halfA, b, halfC); //top triangle
    paint(g, halfC, halfB, c); //right triangle
    paint(g, a, halfA, halfB); //left triangle

     new DrawTriangle();
}

Thoroughly confused about supported resolutions using MDP to VGA adapter

I've read many posts on the topic and I still have no idea what is correct. Some people claim the max res for this adapter is 1600x1200 while others claim they are getting 1920x1200 with it. I have a 24" HP LCD that has VGA and HDMI as the input choices. HDMI limits the res to 1920x1080. Will this adapter run the HP @ 1920x1200 (native resolution) or will it limit it to 1600x1200 ? BTW this is being used on a late 2008 unibody MacBook. Thanks

Problem solved. I picked up the MDP to VGA adapter and was able to use the monitors native res of 1920x1200 but the flicker and wavyness made it impossible to use. And yes the adapter had the current firmware. But what I discovered in the process was that in mirror mode I am unable to drive the monitor at optimum resolution. With that in mind I tried the MDP to HDMI adapter again, unchecking mirror mode, moving the Finder bar to the external display and SHAZAM. I have a rock solid display external display now running at 1920x1200 : )

[SOLVED] Confused about development packages

To build an embedded linux image using minifs utility, I need to install some development packages. The packages listed in the tutorial are named for Debian based distros, with the "-dev" suffix. Some of the listed packages are: libz-dev, libelf-dev, libelfg0-dev, libncurses-dev, etc.
I can't find these packages, and I'm a bit confused. I have read that these packages in Arch Linux have different suffixes denpending on the origin (-cvs, -git, etc.), but I can't find any packages with that suffixes. For example for ncurses:
$ pacman -Ss ncurses
core/ncurses 5.9-3 [instalado]
System V Release 4.0 curses emulation library
extra/cmus 2.4.3-1
A very feature-rich ncurses-based music player
extra/finch 2.10.1-1
A ncurses-based messaging client
extra/moc 20110528-5
An ncurses console audio player with support for the mp3, ogg, and wave
formats
extra/naim 0.11.8.3.2-2
An ncurses AOL Instant Messenger and IRC client.
extra/ncmpc 0.20-1

very good packet sniffer for unix with ncurses interactive mode.
community/vifm 0.7.2-1
Ncurses based file manager with vi like keybindings
community/yacpi 3.0.1-3
ncurses-based acpi monitor.
No ncurses-cvs, ncurses-git, ncurses-svn or the like is found. How can I find development packages?

Confused about Apple IDs used at the store

For the last several years I have been a MobileMe paid subscriber. When I upgraded to Lion, I migrated my @me.com email to iCloud. My current iTunes store account uses a @bellsouth.net email address. I will soon be losing that because I am swapping to Charter Cable. When I go to appleid.apple.com to try and change my id, I get the following error:
I'm confused. Any advice would be greatly appreciated.

You cannot change the Apple ID name from your me.com address; that just doesn't work. You can still use it, though; I've used my mac.com ID all along though I haven't had a .Mac account in years. Just change the email address to which receipts etc. are sent and continue to use the me.com address as your ID name.
Regards.

[solved] confusion about vim and its config files

Hi, Im getting really confused with vim and its /etc/vimrc config, and the per user ~/.vimrc.
On one of my PC's I have an untouched /etc/vimrc and a /home/jason/.vimrc which has:
syntax on
now, on that same PC, if I run
vim .vimrc
"syntax on" in green and yellow as expected, and if I run
sudo vim .vimrc
I also see
"syntax on" in green and yellow, but surely this is opening it as root?
*Edit
Even though there is no .vimrc in /root, and the system-wide /etc/vimrc is untouched/blank
On another PC I also have an untoched /etc/vimrc, and a /home/jason/.vimrc which has:
syntax on
Aswell, and:
vim .vimrc
has "syntax on" in green and yellow as expected, but this time:
sudo vim .vimrc
Has no colour?
I cant explain this, any ideas?
*Edit
To clarify, both PC's have an untouched /etc/vimrc and there is no /root/.vimrc file on either PC

The configuration files in /etc are for system-wide settings. These are the default settings if not overridden by a user's own settings in their home directory.
So running vim as your regular user will use the settings from your home directory.
What does sudo? From man sudo
sudo allows a permitted user to execute a command as the superuser or another user, as specified by the security policy.
So if you didn't specify any setting in the home folder of the user you want to run vim as, and you don't have anything in /etc/vimrc, vim won't apply any custom settings.
I understand all of that, but on both my PC's I have a clean/untouched config /etc/vimrc, and both /root/.vimrc files do not exist, so howcome on one PC I get colour with sudo vim...., and on the other I dont?

Confusing about how to use "protected"

Hello guys,
I don't know how the "protected" works for a long time.
If you know what's the protected really mean,please tell me.
I am confusing as these follows:
I write a class named "parent",which has a protected field x.
1. If I write a class named "son" which extends the "parent" class in the same package and then new parent() to made an instant named "son",can I use son.x to visit??
2.If I write a class named "son" which extends the "parent" class in the ANOTHER package and then new parent() to made an instant named "son",can I use son.x to visit??(Mybe there is two satuations:one is son.x which is written in a "parent" extended class,the other satuation is son.x which is written in any class except what extends "parent" class)

Hello Vishal,
Let-me try help you.
I don´t know if that´s the best solution, but when I use this class, i do as follow.
First I create the container, and after the grid (with the "I_PARENT" parameter)
DATA: r_container TYPE REF TO cl_gui_custom_container,
            r_grid          TYPE REF TO cl_gui_alv_grid.
CREATE OBJECT r_container
    EXPORTING
      container_name = 'CONTAINER1'.
CREATE OBJECT r_grid
    EXPORTING
      i_parent = r_container.
The parameter i_parent associate the container with the grid.
Don´t forget to built the container using the screen painter (or the screen element´s list, but the screen painter is easer).
I hope it helps you.

Confused about wheather to use session or some other technology

i have two jsp pages one is index.jsp and other one is display.jsp,from index.jsp i am passing a string value and collecting it in display.jsp ,after collecting it i am making use of that value in a sql query to display the result from the data base,and i am getting one line (row) of display ,when i repeat the process again that row is over written which i do not want , what i want is as long as i keep sending strings from index.jsp tp disply.jsp the number of rows should be added (as a display in display.jsp)
and i wanted to do that in jsp environment only as i am not aware of struts and some other technology.some sample code of display.jsp is as follows
String INDENT_NUMBER = request.getParameter("indent_number");
query1="select some data from some tables where a.INDENT_NUMBER = '"+INDENT_NUMBER+"'";
while(rs.next){
get some values here to display
like
String item_name =rs1.getString("item_name");
String INDENT_QUANTITY=rs1.getString("INDENT_QUANTITY");
here i want to display row wise data
and now close the while loop
please get me the idea if possible with sample code,i'll be greatfull to u,
thanx

I would add the String you get from the DB to an ArrayList, and store that ArrayList in the session. Then, at time of display, just iterate over the List. I would also look into putting the SQL into a JavaBean that does the work. Take as much of that code out of the JSP as possible.

[SOLVED] Confusion about cross-compiling kernel

I have a MacBook Pro running Mac OS X, and my Arch laptop.
They have different processors (but both Core 2 Duo).
How do I go about compiling the kernel on my Mac, for my Arch machine?
(I'm just going to try compiling the stock Arch kernel at first, then perhaps add the flag in .config for Core2Duo optimisations. Latest kernel.)
Last edited by chrispoole (2009-05-29 12:53:14)

If you're running an Intel Mac, maybe x-compiling won't be necessary.
I think you need to download a toolchain for your target architecture, set it up and compile the kernel *w/ that toolchain*, not w/ your regular one.
I'd suggest grabbing CRUX http://crux.nu/. Compiling the kernel is part of the standard installation process. CRUX is somewhat similar to Arch, w/ the notable omission of pacman.
If playing w/ kernel is all you want, set up some sandbox space and give it a go. No need for x-compiling etc.

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. My iBook library does not show up in iTunes.

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. Some of my iBooks show up in my iTunes but they are "grayed" out. The only books that respond in iTunes are audiobooks and that's not what I'm looking for. Is this a stupid question?

Nevermind - I answered my own question, which is I CAN"T READ ANY BOOKS I purchased in iBooks on my MacBook Pro. If I want to read on my mac I have to use Kindle or Nook. Which means any book I've already purchased through iBooks has to be read on my iPad. Kind of a drag because there are times when it's more convenient for me to read while I'm sitting with my Mac.

I'm confused about the apple ID transition from my aol screen name. Does it continue to use my aol email as my apple ID, converting it somehow or do I need to provide a new email address or just create a new username for the apple ID?

I'm confused about the transition to an apple ID that doesn't use my aol email to sign in. The instructions are vague and ambiguous. Any help would be appreciated.

OK, so if your current Apple ID using your AOL Username (like johndoe), then you need to log onto Manage your Apple ID and EDIT that AOL Username to a valid email address: Apple - My Apple ID
If you have an AOL email address (like [email protected]), and you are not using that as another Apple ID, you can change the AOL Username Apple ID to that. Otherwise, you can change it to any valid email address (which you will have to verify when you change to it).
Hope that clears it up. Post back if it doesn't!

If I download a video from my video camera to a new (current 1/12) iMac 21 inch, how can I burn it to a DVD using the computer itself. Is this possible? Do I need to buy additional software. Two salespeople at the Apple were a little confused about this.

If I download a video from my video camera to a new (current 1/12) iMac 21 inch, how can I burn it to a DVD using the computer itself. Is this possible? Do I need to buy additional software. Two salespeople at the Apple were a little confused about this. Thank you.

The DVD recorder I'm referring to is one I've use for years. It is not attached to my aging iMac in any way. I simply play the video from my camcorder (mini-dv tape based Canon HV20) into the DVD recorder and create a DVD that can be played in any DVD player. I can only do minimum editing so what goes in is what I get. This has been fine for creating dupes of the various things I shoot.
If I buy a new iMac (21 inch), I'd like to be able to download the video to the iMac through iMovie, work with it to whatever degree I wish, and burn it to a DVD that can also be played in any DVD player -- or to use as a master to dupe copies.
What I'm understanding from you and others is that this would be possible if Apple had included iDVD in the software that comes with the iMac, or if I purchase the iLife Family Pack, or buy the correct version of Toast. I'm hoping I can persuade Apple to sell me an iMac with iDVD installed.
Essentially I want to move from a basic process of creating DVD copies to the more sophisticated process of creating one from an iMac.
Thank you again for your help and wisdom.

I'm horribly confused about student licensing and commercial use

As the title says I'm horribly confused about student licensing and using it for commercial use.
I currently have a Student Licensing version of Adobe Creative Suite 4 that I purchased through my school's journeyEd portal.
Seeing how CS5 is now out I was browsing looking at prices (why not upgrade while I'm still a student, right?) and while browsing I bumped into one source that says that Student Licensing can not be used for commercial purposes, and this is when the confusion started. I remember reading before that we are able to use student licensing for commercial purposes, okay time to google search. I found one Adobe FAQ that says I can. .
http://www.adobe.com/education/students/studentteacheredition/faq.html
" Can I use my Adobe Student and Teacher Edition software for commercial use?
Yes. You may purchase a Student and Teacher Edition for personal as well as commercial use. "
and I found this old thread;
http://forums.adobe.com/thread/314304
Where an poster listed as an employee of Adobe states
"There is no upgrade from the CS3 Educational Edition to the comparable CS3 editions sold in non-academic environments. If you have an educational version of for CS3 obtained legitimately (i.e., you qualified for the educational version when you obtained it), you may continue to use that software for the indefinite future, even for commercial use! You cannot sell or otherwise transfer that license, though! When the next version of the Creative Suite is released, you will have two choices: (1) If you still qualify for the educational version, you can buy a copy of that next version (there is no special upgrade pricing from one educational version to another; the price is already very low) or (2) you can upgrade from the educational version of CS3 to the full version of the next version of the Creative Suite as an upgrade from CS3 at the prices published at that time. "
Okay cool, hmm what this? Adobe is asking me if I want to IM with live costumer service agent, sure why not? Then the conversation started and I asked her my question about using my CS4 license for commercial use, she asks for my product code and email to verify my product, then informs me I can purchase the upgrade version of CS5 and use that for commercial, okay great, but not really answering my question. I reword it and give her a link to that FAQ page it goes like this. ..
"[CS Rep] : [My name], I would like to inform you that Adobe Student and Teacher Editions are not allowed for
commercial use.
[CS Rep] : However, you can upgrade your current software to a normal upgrade version, and you can continue
using it for commercial purpose.
[Me] : Then is the FAQ page mistaken? Because it is very misleading if it is. But thank you for the information.
[CS Rep] : You are welcome.
[CS Rep] : I apologize for the misleading information in the FAQ."
. .And after that, I went back to being confused.
SO my questions are. . . Can I or can't I use my Adobe Creative Suite 4 student licensing for commercial purposes? and If I purchase a Student Licensing of CS5 can I use that for commercial purposes as well?
Sorry for the long post, I just want to be perfectly clear on what I can and can not do with my purchase.

The rules differ in various parts of the world. In North America you can use it for commercial work.
There are no student/academic upgrades. The pricing is so low that in many cases you're better off buying another full student license but you are eligible for upgrade pricing for commercial versions once you're out of school.
You may not transfer the student license in any way.

I'm new and confused about "connection" things

I'm new to BlackBerry--I have an 8320 Curve, I'm a small business owner and I'm not connected to a BES. I use the BB Desktop Manager to synchronize with Outlook and to back up my BB and I've done pretty well on most things, but I still have a few things I'm confused about. In this forum, I'll ask my "confusion questions" concerning data options.
I have a "pay as you go" data plan with AT&T, my provider, because there is virtually no cell reception at my home where I also work. (I'm not using my BB for email since I'm in front of my computer most of the time). I have a home network set up and I've incorporated a router that supports wireless. I've connected a netbook to the wireless network and used it to surf the Internet, so, I know my wireless connection works. I've also managed to create a wireless connection on my BB to this network and on the Home screen, it will display my wireless network's name when I'm here at home, so, I know the device is connected to my network.
BUT, I don't think I'm actually using my home wireless network...I tried the other day by browsing the Internet and then AT&T told me I incurred data charges--which I thought I shouldn't have if I wasn't using their network. Either I'm wrong about assuming they won't charge me if I use my network or I have something set up incorrectly on my BB...can anyone provide some guidance?
Next, I don't truly understand what BIS is...I searched through the KB and couldn't find anything that actually defines BIS...could somebody please explain what BIS is?
Finally, can somebody please explain the difference between "mobile network" and "wi-fi"? It seems, if I turn off "mobile network" I have no connection at all, including wi-fi. Is that the way things should be? But, I can turn off wi-fi and still get a connection (if I go outside as far from my house as possible and face south <g>).
Thanks...and now I'm off to the BB Desktop Manager forum to ask a few questions there!
Solved!

Hi and Welcome to the forums!
I can help you with one or two of your questions:

BIS is Blackberry Internet Service...a service, hosted by your carrier, that provides a conduit between internet facing email systems (e.g., Yahoo, GMail, etc.) and your BB. Inside of BIS, you create conduits for each of your email providers that you desire to receive OTA email for on your BB. BIS will check your provider on a periodic basis (documented to be every 15 minutes) and only when there is something that needs to come to your BB does it generate any traffic over the carrier network with your BB. BIS is an add-service, only available to those who, from their carrier, contract for The Blackberry Data Plan (as it is usually called) -- a generic data plan is not usually adequate to have access to BIS.

Mobile Network is your carriers network...data and/or voice services provided OTA for your BB. WiFi is wireless networking (802.11a/b/g/n) through your home WAP, hotspots, etc. I don't know if turning off Mobile Networ should or should not affect your ability to continue to use WiFi...I would think they are separate, but I don't have a BB model with WiFi.
I know nothing about the pay-as-you-go programs, but from all you describe, it seems that you may well be using your carrier network at times. You will need to find out (and there are others here who know) how to shut off your carrier network yet leave WiFi running so that you don't incurr the costs of surfing via the carrier network.
Hope that helps a little!
