How to evolve a graph with only one loop

1. how to continue to add new nodes to a graph with only one loop
would like to use graph traversal like my previous post to traversal a binary tree, but this time, it can
loop forever, i mean it traverse all nodes in whole graph in the meanwhile it add new nodes too
assume maximum number of joint is 2 or 3
computing nightmare

I just realised that you weren't talking about cyclic graphs (in the case of 1 cycle) here, but meant a single pass traverse and mutate.
What you don't specify is how the new nodes are being supplied. If they are supplied up front, then the loop will of course terminate once all the inputs are addressed, rather than going on forever. If they are being supplied from time-to-time,
then you need to have some sort of event-wait on input. The traversal could have a move-next something like this
If at end of tree with no new nodes, wait for input
If at end of tree, with input, reset to start
If at insertion point for new node at top of input queue, insert that
Move to next node in tree
This seems the sort of thing that would naturally be coded in a functional language as a tail recursion rather than an iteration.

How to connect many devices with only one FW800 port in iMac?

Hi,
I am upgrading to a new Intel iMac from a 2004 vintage Dual2.0GHz PowerMac. I currently have 8x d2 Quadra drives chained by FW800, and 2x Iomega drives connected vis FW400 hub which also connects HD cams.
My questions is that with only one FW800 port in iMac, I think my devices connectivity is the following?
(1) Get a FW 800 hub (I can only find 2 port ones at the Apple store and BestBuy)
(2) Connect the d2 Quadras to one port of the FW800 hub
(3) Get a FW 800 to FW 400 cable
(4) Connect my 6 port FW400 hub to the 2nd port of the FW800 hub
Thanks for reviewing this solution, and I would also appreciate other suggestions or hear about your experiences if you have a similar set-up.
Will

In addition to your listed considerations, you should consider the following.
Many storage needs do not required FireWire 800 speed. For example, USB 2.0 works fine for your Time Machine backup drive. If you are just storing user data such as your iPhoto or iTunes media files, USB 2.0 is more than fast enough. So, as much as possible, if any of those external drives have USB 2.0 connections and the data storage does not need FireWire 800 speed, offload as much as possible to USB 2.0. I used to be a +FireWire snob+, but since getting an Intel iMac, I find that USB 2.0 works quite well for most data storage purposes.
There are new hard drives that are power efficient and as large as 2TB. Consolidate your data storage needs onto a smaller number of very large drives, partitioned as needed. This will make your setup more reliable (smaller number drives), and save reduce power consumption. If any of your current externals are SATA, you can probably replace the existing drive with an extra large one.
So, I think you setup should be, extra large FireWire 800 drive connected to the FireWire 800 port directly. Using a 9-pin to 6-pin cable, connect the FireWire 400 hub. Connect any non-storage FireWire 400 devices there. Do some data transfer testing to make sure having the 400 hub there on the chain does not cause the 800 connection to slow down.
Connect other drives as needed using USB 2.0, existing or new. Retire the smaller of your external drives.

Create a Graph with only one set of data? Threw serial

I feel this is a simple question, but I am over thinking it. I am trying to make a program that takes data that is sent threw serial Rs232 from a device, and put that data both into a file and display a live graph of the data (saving the graph would also be great). The devise is strait forward it gives me data when it is don't making the test. After it has the data is sends it and it is always in this form, (ignore Quotes) "[ 122.8 PSI ]' where "122.8" will always be 5 characters and the decimal point stays the same.
I would like to take Ex. 122.8 and plot that on y and use the line number from the text file as the x value. How can this be achieved?
Currently I am displaying the values in a list because I can't figure the graph out. But attached is my messy code and a sample of data that gets sent.
P.S.. The data list can get as long as 2000 or more.
side question... when the program is built into an EXE when using serial, can the user change what port?

Well, that's called Rube Golberg code.
All that you have to do is convert the string to a numeric (i.e. a single Scan From String not your match pattern functions) and wire it to a chart. The chart's x axis by default will increment by 1 with each sample written so reading the x axis from file is silly. Be sure to set the chart history. Since you are already writing the data to file, why write it again? Either write the full string or just the value. Your second while loop becomes unnecessary and if for some reason you needed it, it would only record the very last value.
Don't open the file with each iteration. Place that outside the loop.

How to sync 2 devices with only one iTunes ?

I have iphone and my gf has ipod touch. We only have one computer - win 7.
How can we sync it, so we can both have different music and apps on each device?

The easiest way is method 2 from this article - just sync certain playlists to each ipod.
http://support.apple.com/kb/ht1495
If you both want your own song ratings and play counts, use method 1. It's more of a pain to set up and keep updated when new music is added, though.

HT201269 me and my brother both are having iphone 4s we just want to exchange phones with each other also the whole data from one iphone to other is this possible or how can i do that with only one itunes?

just want to move data between two iphones using one itunes.

Make sure your computer iTunes is up to date. (iTunes 11.1.1)
Now, do it one iPhone at a time; When you connect and select iPhone in computer iTunes sidebar (iTunes > View > Show Sidebar), what iPhone name do you see?
iTunes is smart enough to tell the differences if each has a unique name.
Point One checked.
Right click on iPhone name in Sidebar and choose Backup.
Do the same for the second iPhone.
Make a copy of the backups in computer to another location (Just incase something gone wrong)
Where iTunes backups are stored on computer http://support.apple.com/kb/HT4946
Point 2 checked.

HT204088 How how can I synch my ipod + iphone music to my new computer? I get the same error "my ipod or iphone is synched with another itunes library.An Ipod can be synched with only one itunes library at a time. What would I like to do Erase and Synch

How can I synch my ipod & iphone music (purchased from itunes on my old laptop) to my new laptop? I keep getting the same message on my itunes on my new laptop: " The ipod/Iphone is synched with another itunes library. An ipod/iphone can be synched with only one itunes library at a time. What would you like to do - Erase and Synch or Transfer Purchases?" What do I do?
A couple of other items:
1) I am guessing Apple does not keep a history of all my music purchases? As I did not have my entire library backed-up anywhere, and relying on the music I have on my ipod and my iphone as my only source of itunes music....I have lost over 500 songs!!!
2) I used to have an Apple account under another account name, and since have switched to a new account name. Is there anyway to find the history of purchases from my old Apple account name and transfer these over to my new account name and onto my new laptop?
I hope someone can help, I am having a very difficult time trying to obtain answers. Angie

The iphone/ipod is NOT a storage/backup device. Not maintaining a backup copy is a big mistake.
You can transfer itunes purchases from your iphone/ipod to your computer:
Authorize your computer for all accounts and then click File>Transfer Purchases

How to make 1D Array but with only one element filled in Real Time

Hi folks,
here I am with another question. I want to implement an prediction discrete state space observer which is going to run on a CRIO real time target. I am going to do it just like in the example which comes with LV.
I have some questions regarding the input and outputs which in the example those are "dummy".
My model is a SISO model, but the function "Construct SS model" returns parameters (A,B,C,D Matrices) as 2D arrays, so once you connect the cluster model into the Discrete Observer model, it takes y and u as 1D arrays despite of the fact that there is a SISO model.
I realized that the function I am using in the simulations, uses 1D arrays but with only one element filled:
Does anyone knows how to implement such 1D arrays in Real Time? I guess the way to do it is preallocating one array of zeros of size 1, and then recirculating it through some SR, and replacing the element with my real input and output, but at the dummy.vi, they are using a simple "build array"
function.

Ok, I did it that way. But I am facing another problem right now...
At some point the Discrete Observer return a NAN array, you will see the code in the code snippet?
I get rid of that component by component, but the observer gets "stuck" in it. So my Control law is zero... but the state stimate is NAN.
Also I am attaching the VI.
I do not know why, since in the simulation program all runs well. any thoughts? Maybe the internal numeric precision of the State Space Model?

How can I play different videos with only one MediaPlayer?

I want to play two videos with only one MediaPlayer:
private static MediaPlayerBuilder mpB;
private static Media mLogo;
private static Media mSaludo;
private static MediaPlayer mpLogo;
private static MediaView mvLogo;
private static Group gLogo;
public void start(final Stage stage) {
mLogo = MediaBuilder.create().source(myGetResource(VIDEOLOGO_PATH)).build();
mSaludo = MediaBuilder.create().source(myGetResource(VIDEOSALUDO_PATH)).build();
mpB = MediaPlayerBuilder.create();
mpLogo = mpB.media(mLogo).build();
mvLogo = MediaViewBuilder.create().mediaPlayer(mpLogo).build();
gLogo.getChildren().add(mvLogo);
sActual = new Scene(gPozos, WIDTH, HEIGHT, Color.BLACK);
stage.setScene(sActual);
stage.show();When I want to play mLogo:
sActual.setRoot(gLogo);
mpLogo.play();Then, when I want to play mSaludo I do this:
mpLogo = mpB.media(mSaludo).build();
sActual.setRoot(gLogo);
mpLogo.play();or this:
mpB.media(mSaludo).applyTo(mpLogo);
sActual.setRoot(gLogo);
mpLogo.play();or this:
mpB.media(mSaludo);
sActual.setRoot(gLogo);
mpLogo.play();But is impossible to change the Media. It doesn't work. Sometimes I play mLogo video and sometimes (depends on the code) the video mLogo doesn't start and I see an image of the first keyframe and nothing else. I have no exceptions, no errors, nothing.
I want to play mLogo and then mSaludo. How can I do this?
Thanks

How use two templantes with only one job ?

I have two templantes and want use with only one job.I use with input one xml data file !!
Is this possible?
Please Help!!
Thanks,
Bruno.

I probably missed this one earlier or felt that since it referenced an XML data file that I couldn't provide a definitive answer. I'm still not sure I can because we don't use XML for our data files, but use the "field nominated format". An expansion on Tammy's information: 1. use a multi-step job with each b task calling a different MDF. With this correction, it assumes that you either have access to set up the tasks/jobs yourself or can convince your Central administrator to do so. What happens is that TASKA is set up to reference FORMA and TASKB is set up to reference FORMB. Then a job is set up that causes both TASKA & TASKB to be ran. This will likely result in two different print files being sent to the printer. That may or may not be desirable, depending on whether your printer is set up to do something special between each print file (insert separator page, offset, whatever). Personally, I don't recommend this as it can quickly cause an unnecessary proliferation of tasks and jobs (we print 100's of differing form combinations with a single job definition). 2. I can't really address this as I didn't even know that a single form could cause another to be called. I would expect that unless the "base" form (say it is FORMA) is to always print with the secondary form (FORMB) it is restrictive and has the potential to cause a proliferation of FORMA files for the various combinations that are to be printed. Maybe it is possible to have logic to check the value of a data field to control what forms get called. 3. If you pass the XML file through a translation step and then through the transformation agent (maybe it can be done in a single step) this should work. It does add another step to the job as well as requiring learning to use the transformation agent. Depending on the combination of forms to be printed, you might need a different translation definition for each one, or at the very least have a data field that you can check the value of to determine what ^form commands to put in the output file. 4. My recommendation is based on assuming an XML data file has the same capabilities as a field nominated file. Within a field nominated file are various print agent commands, including references to data as well as which forms are to be printed (and a whole bunch of other commands). An XML file should have the same features - I just can't say what they might look like. If your current data file has no "form" reference but depends on the job/task definition you might have to stick with option 1. If it has a "form" reference, then you just need to insert additional references for additional forms. Then it is up to the source of your data (or a transformation agent step) to specify which forms are to be printed. For example, in field nominated format, the file might look like: ^job XYZ additional parameters ^form FORMA.MDF ^field FIELD1 data ^field FIELD2 data ^form FORMB.MDF ^field FIELD1 data ^field FIELD3 data or it might look like the way our files look: ^job XYZ additional parameters ^global FIELD1 data ^global FIELD2 data ^global FIELD3 data ^form FORMA.MDF ^form FORMB.MDF As you can see in the first example, there is a reference to the form followed by all fields that go on it followed by another form reference with the fields that go on it. This particular method, using all "^field" commands for defining the data requires that data duplicated between the forms be duplicated. (Or, the use of some ^global commands like the following.) In the second example, all data is defined first using the "^global" command followed by all of the form references. This allows for the data to be defined only once. If there is something unique regarding a particular form the field can be ^global at the beginning or it can be ^field b after the ^form reference (similar to the first example). As previously mentioned, the XML file should have the same capability but in XML notation, something like the following (forgive me as it has been years since I took the XML class and don't use it in my daily work so the actual format could be wrong, not to mention the actual labels): <job name=XYZ,option=aaaa,option=bbbbbbb> <form name=FORMA.MDF> <field name=FIELD1, value=xxxxxxxxxxx></field> <field name=FIELD2, value="xxxxxxxxxxxxx"></field> </form> <form name=FORMA.MDF> etcetera </job> or maybe: <job name=XYZ,option=aaaa,option=bbbbbbb> <global name=FIELD1,value=xxxxxxxxxxxx></global> <global name=FIELD2,value="xxxxxxxxxxxxx"></global> etcetera <form name=FORMA.MDF></form> <form name=FORMB.MDF></form> </job> or even (but I doubt it): <job name=XYZ,option=aaaa,option=bbbbbbb> <globals> name=FIELD1,value=xxxxxxxxxxxxxxxx, name=FIELD2,value="xxxxxxxxxxxxxxx" </globals> <forms> name=FORMA.MDF, name=FORMB.MDF </forms> </job>

An iPhone can be synced with only one iTunes library at a time

I recently bought a MacBook Pro, and I figured it would be pretty simple to move my iPhone to sync with iTunes on the Mac from iTunes on my pc, afterall it is the same program and both are designed for the iPhone.
I have been successful in getting the Contacts and Calendar to sync, but the Music, Applications, Video and a few other things give me this message when I check the sync box:
"The iPhone is synced with another iTunes library. Do you want to erase the iPhone and sync with this iTunes library? An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library."
Obviously, I don't want to erase everything. Actually, I don't care about Music, Videos, Podcasts or Ringtones as I don't have any, but I do care about Photos and Applications. Actually Photos I can reload too, but I don't want to loose the apps I have purchased with the iTunes App Store.
I even tried going back to the PC and unchecking the Sync boxes on it, hoping this might disassociate it from the phone, but now even on that PC I get the same message.
How do I disconnect phone from the old iTunes and be able to sync it to the new iTunes? This should be simple right?

I made an appointment with a Mac Genius and I will say that while it was better than getting to talk to India on a poor quality phone call it was just about as helpful. Sure she was cute and friendly, but I left without my issue resolved and was surprised that I didn't even get a followup from anyone asking about my experience (hence my venting here)
Anyway, I found a solution for my issue here: http://tinyfish.net/2008/07/18/how-to-sync-iphone-with-multiple-computers/
This is a real solution to the issue, and has the benefit that I can do this to as many machines as I need and sync at any of them instead of just one. Hopefully, Apple doesn't delete my response since it truly is the answer to the problem and others might be looking for the same solution.
