What is the best way to program DANI Robot to execute several movements(i.e forwards,rotation,...) in sequence?

How to design a program that autonomously controls DANI Robot to navigate through a maze? No sensor, and path is given. Required movements will be moving forwards and rotate clockwise and counter clockwise.

Hi Patrick,
You could implement this using sequential or state-based architecture. With no sensors and a predetermined path this falls more to your ability to accurately control the motors on your robot.

What is the best way to sync iCal, AdressBook, etc on several devices? (iMac, MacBook, iPad and iPhone)

I have several Apple devices (iMac, MacBook and iPhone) and I was wondering what is the best way to sync iCal, AdressBook, etc on these devices?
I have an iCloud acount as well, but how to sync without seeing enteries double (iCal)?
Many thanks!

iCloud should not cause duplicate entries in Calendars unless you are syncing using iTunes as well as Wi-Fi. No need for both.

What is the best way to use single shot drum sounds?

I have a huge collection of wav. format single sound drum sounds that I use in FL Studio. What is the best way to program drums in GB using them besides buying iDrum? I like the flexibility of using drums from different kits when I make my music so I kind of get board using a preset drum kit from GB even layering 3-4 kits isn't as nice as choosing each individual drum sound.

Would be great to have more info but on a 24fps timeline with 24fps footage, you can simply right click and change the speed/duration to whatever. It'll be more jittery than smooth 60fps slow-mo. If your footage is shot at 60fps and you are editing on a 24fps timeline, just select the clip and right-click and choose MODIFY>Interpret footage and change the fps to 23.976 and you're done. Now when you drop that clip on the timeline it's in smooth slow-mo. Or, you can just toss the original clip on the timeline and change the speed/duration setting to 40%. Pretty much the same thing although the former is better if you need to add any warp stabilization to the clip. Anything you want to speed back up you can either duplicate the clip in the project panel and change it back to the original frame rate OR you can simply adjust it on the timeline to 250% speed which is back to normal. Good luck!

I want to sell my old macbook air, what is the best way to get my files and programs off of it?

I am going to sell my macbook air (2011) as I am replacing it with a macbook pro retina. I want to remove my files and programs from it before I sell it. What is the best way to go about this?

1) Perform a Time Machine or Cloned image backup of your system.
2) Test the Clone tomake sure it works, by booting to it (using the option key).
3) Boot to the Recovery Partition, then perform an erasure, followed by a reinstallation of the OS.
4) Shut off the Mac, after instllation and before the reboot. This will permit the next user to experience a "fresh out of the box" experience.
5) Use the Time Machine or Cloned image to migrate your apps, users & files to your new system, using SETUP ASSISTANT. Do not use Migration Assistant.

What is the best way to make a program fit different monitor resoultions?

In our lab all our test stations have 1280x1024 resoultion monitors. In the "other lab" all the test station monitors are 1440x900 resoultion.
Now I am tasked with making my programs run on the test stations in the other lab. I have tried setting the options "maintain proportions of windows for different monitor resoultions" and "Scale all object on front panel as the windows resizes" and of course neither one of these options really does what I would expect it to do.

I resize the Front Panel when the program start to fit the monitor resolution. After that, I use the "SBE_Determine If Screen Resized.vi" from TomBrass (http://forums.ni.com/t5/LabVIEW/Resizing-controls-on-a-tab-control-within-a-pane/td-p/1520244 ). This vi is very useful if you don't want to monopolize the CPU with the "Panel Resize" event.
I don't like this function for a couple reasons. First for the example you don't need any custom code to handle the window resizing, just use a couple splitters. Even if you did need to handle the resize, you only resize after the mouse is up after the resize which is not how normal Windows programs work they resize as the mouse moves. So I modified the VI to resize objects as you resize the window. Then because doing this can generate 100 events very quickly, I use a boolean in a shift register to make sure that we only handle the resize event if there is no new resize events after 0ms. This essentially makes a lossy queue and handles the last resize event.

What is the best way of converting a Top Level VI into a 'sub vi' - or function ( without duplicating programming)

Hi,
General question here about design architecture, which i keep running into, but haven't found a really good solution. If i write a 'Top Level VI' to do something, what is the best way of converting it into a subVI - which is call-able from other VIs, while still allowing the top level VI to have synchronised feedback/indicator updates.
I guess the point is that when something is a top level VI you write gui logic about what happens when someone clicks buttons or whatever - which you don't want in the 'sub vi' version.
I did at one point try having a hidden boolean button that was an input to the subVI which would let the VI know if it was supposed to be doing the front panel stuff - or simply running as a subVI. This isn't really ideal though - since it would be better to be able to hive off the grizzly useful stuff from the fluffy - front panel updating stuff - having them together makes the VIs rather untidy. More annoyingly though, if you have the front panel version of it running - say waiting for you to hit 'go', it breaks all the other VIs that use it as a sub vi - since they can't compile when a sub vi is already running.
Another possibility that i tried was to basically duplicate the vi so that there was a backend part, and a front end part - and when i click 'go' the backend part is called as a sub vi. The problem with this is that it really limits the interface that the user gets - since none of the controls on the front panel update with the results untill the sub vi is over. I guess again i could solve this by passing references to some of the controls to update them in the subvi - but this doesn't really seem like the ideal situation if the subvi is called by something else without the same types of controls etc.
One final idea i had was to essentially paste all the controls in the VI into a global variable file, and make the sub vi update them, and the front panel VI read from them. This seems to 'work' - although clearly it is a work around rather than a proper solution - since i spend loads of time worrying about how i update cluster variables in the global - reading and writing.
Does anyone have any guidance on what they do to solve this problem?
JP

You could run a subvis in a Subpanel on your top level. Lets you see the current data while the subvi is running.

What is the best way to set up iTunes on our home network so all family members have access to all of our itunes library, even music we don't have on the cloud?

I have five different people using 10 different apple devices on one itunes account in our family. We have had trouble sharing. What is the best way to set up itunes on our home network? We have purchased music that sits on icloud, but we also have music we have imported from our previous cd library. Our itunes program keeps crashing and dumping everyone's playlists. So far we have all been using just the one desktop computer to sync to because we can't figure out how to share the same librarly and playlists on multiple computers in our home so devices can be synced at any location as well as playlists and purchases be made.

What is the best way to set up itunes on our home network?
One iTunes library per person. One iTunes account per person.
If people wish to share songs, they can make copies.
When the inevitable day comes when the kids get older, you will not have to come back here and post asking how all that stuff can get separated!

What is the best way to verify default heap size in Java

Hi All,
What is the best way to verify default heap size in Java ? does it vary over JVM to JVM . I was reading this article http://javarevisited.blogspot.sg/2011/05/java-heap-space-memory-size-jvm.html , and it says default size is 128 MB but When I run following code :
public static void main(String args[]) {
int MB = 1024*1024;
System.out.println(Runtime.getRuntime().totalMemory()/MB);
It print "870" i.e. 870 MB.
I am bit confused, what is the best way to verify default heap size in any JVM ?

Hi Kayaman,
Sorry but I don't agree with you on verification part, Why not I can verify it ? to me default means value when I don't specify -Xms and -Xmx and by the way I was testing that program on 32 bit JRE 1.6 on Windows. I am also curious significant difference between 128MB and 870MB I saw, do you see anything obviously wrong ?That spec is outdated. Since Java 6 update 18 (Sun/Oracle implementation) the default maximum heap space is calculated based on total memory availability, but never more than 1GB on 32 bits JVMs / client VMs. On a 64 bits server VM the default can go as high as 32gb.
The best way to verify ANYTHING is to address multiple sources of information and especially those produced by the source, not some page you find on the big bad internet. Even wikipedia is a whole lot better than any random internet site IMO. That's common sense, I can't believe you put much thought into it that you have to ask in a forum.

What is the best way to submit a Concurrent Request over a DB Link?

Hi,
We have a requirement to submit a Concurrent Request over a DB Link. What is the best way to do this?
What I've done so far is I've created a function in the EBS instance that executes FND_GLOBAl.APPS_INITIALIZE and submits the Concurrent Request. I then call this function remotely from our NON-EBS database. It seems to work fine but I found out from metalink article id 466800.1 that this is not recommended.

What is the best way to double buffer in this case and how to do it....

currently I have
public class Frame1 extends JFrame{
//inside this class I call up circle class, rectangle class, etc.... to draw
}I am making a "paint" program, and I have individual classes to handle the paint methods heres an example:
abstract public class Shape {
    public Shape() {
    public abstract void draw(Graphics g, Color c, int x, int y, int width,int height);
}and then....
public class Circle extends Shape{
    public Circle() {
    public void draw(Graphics g, Color c, int oldx, int oldy, int newx, int newy) {
        g.setColor(c);
        g.drawOval(Math.min(oldx, newx), Math.min(oldy, newy), Math.abs(oldx - newx), Math.abs(oldy - newy));
}There is also a Rectangle class, line class.... etc! So my question to you is the following... what is the best way to implement double buffer in the individual classes? And how to do it?? And also.... the drawings should be kept inside a jPanel.
Any bit of help is much appreciated Thank you!!

You don't need to do double-buffering. Swing
components are double-buffered by default. Just make
sure you override paintComponent() and not paint().
And even if you had to, why would there be any
difference in implementation for your classes whether
they paint to on- or off-screen graphics?I need to override paintComponent()? what if I don't...
I am using JBuilder2005 and they automate somethings for me. So thats how they did it when they created the application they did this....
public class Frame1 extends JFrame{
/*** all my code here***/
public class Application1 {
    boolean packFrame = false;
     * Construct and show the application.
    public Application1() {
        Frame1 frame = new Frame1();
        // Validate frames that have preset sizes
        // Pack frames that have useful preferred size info, e.g. from their layout
        if (packFrame) {
            frame.pack();
        } else {
            frame.validate();
        // Center the window
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        Dimension frameSize = frame.getSize();
        if (frameSize.height > screenSize.height) {
            frameSize.height = screenSize.height;
        if (frameSize.width > screenSize.width) {
            frameSize.width = screenSize.width;
        frame.setLocation((screenSize.width - frameSize.width) / 2,
                          (screenSize.height - frameSize.height) / 2);
        frame.setVisible(true);
        try {
            jbInit();
        } catch (Exception ex) {
            ex.printStackTrace();
     * Application entry point.
     * @param args String[]

What is the best way to use a SSD for Photoshop/photo editing?

Computer hardware newbie here: I do a significant amount of photo editing work and for a very long time I've experienced Photoshop, Bridge and Photomatix crashing constantly (usually due to insufficient RAM) or just generally taking forever (Bridge took forever to load the thumbnail/preview extractions in a folder full of images, Photoshop took forever to save images and Photomatix took ages to load/merge a set of bracketed photos). Here are the typical error messages I'd get: http://pastebin.com/J9byczse
As a professional photographer, constantly running into that sort of thing is quite aggravating, so to hopefully avoid ever having to deal with that again I invested in a new custom built computer. It's Windows 7 Professional 64 bit with 32GB of RAM and a 240GB SSD; I'm using the 240GB SSD as my boot drive/OS, all of my programs are installed there, and the page file. My photos and data are stored on several HDDs. I have yet to install any of my photo editing software (Photoshop CS6 Extended, Lightroom, Photomatix etc) to the new computer yet since I'd like some advice first.
My basic question is this: what is the best way to take advantage of the SSD (and the computer in general) when it comes to my photo editing software?
Specifically...
1. If I have a folder of photos I'm working on, should I move it to the SSD and then work on them from there in order to take advantage of the speed of the SSD? Would this make any difference in terms of speed if the photos are located on the SSD vs. an internal/external HDD?
2. Most of what I've read online seems to recommend two separate SSDs, one for installing/booting the apps and one for cache/scratch. Does it matter if I use my 240GB SSD for both?
3. This is a fairly new computer and the SSD is already almost half full (102GB used, 120GB free) *WITHOUT* any of my photo editing software installed yet. I'm concerned about how fast that remaining 120 GB may fill up. As it fills up will I lose the speed advantage of the SSD vs. a regular HDD?
4. Sort of similar to #3, but should I bother moving any of my other non-photo editing programs/caches off of the SSD to a HDD and would there be any major difference in the speed/lifespan of the SSD if I did so? It's mostly Firefox and Chrome and their caches that I'm concerned may be a problem if they remain on the SSD.
Thanks for any help!

If you have an SSD you can run the cache and programs on the same drive. However, many recommend a scratch disk size of 100-200 gigs so that will not work here unless you opt for a larger SSD. Otherwise an internal spinner is recommended that does not contain the program files, or idealy any other files that may want to get acessed at same time (only one read/write head per drive).
With 32 gig of RAM you may not need the constant use of the scratch drive unless working on large images with lots of layers. So see no advantage to moving folder to SSD for temp work environment.
From what I read the new crop of SSD do not have the wear problems of the older versions.

What is the best way to back up itunes library

I have my imac time machine program set to back up my computer every day to an external hard drive. I recently updated itunes and I lost some of my songs. I tried to find them in time machine but I couldn't find them. itunes support was good and I was able to download them again but I'm wondering what is the best way to back up my songs so I don't have to ask to download them again. I have a lot of podcast that I don't want to keep hard copies of they aren't as important to me.
As of now I have all the songs burned to a music cd but I just want to know if others think that time machine isn't the best back up for itunes and the cd's are the way to go.
Thanks for the help.

How is the drive attached?
Can you open large files on the drive with other programs?
Are you running any drive compression or acceleration programs (some drives arrive with these installed)?
Can you reformat the drive and try again?
Hi Kirby,
I attached the UltraMax Plus with a USB cable. The UltraMax powers the cable so power is not an issue. I can open other files. Also, there is 500GB of files on the drive so I cannot re-format it. Although, I noted I could import the entire Aperture Library. However, I do not want to create a duplicate on my machine because that would be defeating the purpose of the external drive.
