Some question about flex and facebook, and saving server work!

Hi guys im starting to develop facebook application and im not surre what is the better way to connect my app to facebook.
first option is to pull all the data from facebook through PHP and then send it to the app. or getting the data directly to my app through actionscript.
what is the better option? the first option takes more server work, is that something to consider or its irrelevant to small-medium apps?
another thing , does PHP integrets better whit facebok than actionscript? does the APIs of PHP and ActionScript are the same??
what would u say is better??
10x ahead, and sry if this is not the right forum!

imm there is a tuttorial

Some questions about Unity 4.0 and IPC

I have a couple of questions and I was looking for "real world" answers, not specific answers from the design guide.
1.What is this bandwidth requirement between Exchange and Unity and what is it used for?
2. What sort of issues would we experience if we placed the Unity UM Server at the Colo and placed the Exchange server at the customer premise; with a single T1 between the sites?
3.What else is involved with a Unity UM install vs. a Unity VM install?
4.Does the Unity UM and Exchange servers have to be running AD?
5. Can Unity or the Exchange box be the Domain Controller? Or does it need to be a separate server?
6. Where does a vm message get streamed from? The Unity server or the Exchange server?

No you do not pay for FaceTime. It uses your WiFi network, so if you have access to WiFi it is free.
There is no server required for FaceTime, it will use a direct device to device protocol.
I can't answer the question about using phones in different countries as that will depend on if you buy a phone that is locked to a carrier.
If you buy a phone in Germany and it is locked to a German phone network then it will most likely not work with a SIM from Turkey. You would need to buy an unlocked phone which are very expensive as they do not have any carrier subsidy applied to the price.

Some questions about Java deployment steps and techniques

All my java experience is coding and testing in my local machine (where, of course, a jre is available), but ... when I deploy to other people, they may not have a jre or they may have a different version of it than the one needed to run my application. I've read different stuff online including jars and java web start but still I have many questions.
(1) first one first, Sun contradicts common sense, when it says that i can redistribute my own customized light version of their jre by taking out some files (java.sun.com/j2se/1.5.0/jre/README). there are two ways for me to get a jre: Way one is by downloading one from Sun, the download comes as an *.exe file and I don't see how I can take files out of it, so do you know how?. Way two would be by simply copying the set of files i choose (according to that Readme) from my current jre installation (the one on my \java\jdk\jre directory), does this make sense?, (if you're under windows) doesn't an installed version of a jre need a couple of dlls plus some new registry entries?, this contradicts common sense, if I'm not wrong, that Readme is a nonsense, but since that readme is at each of us jre installation \java\jdk1.x\jre\Readme, it can't be a nonsense, therefore I'm wrong, therefore the answer is either Way 1 or Way 2, HOW? ... or maybe there's a Way 3?
(2) Say I never read that Readme so I download the jre (as an exe) to bundle it along with my application in a jar ... now I'll give my neighbor either a jar with two exes or two exes jars ... is there a way to make a jar so that two files get executed? ... if the answer is No and I have competition from a second neighbor, then I believe I'm asking my first neighbor to choose my application based on our friendship, that's not reasonable if we are doing business, so Java loses.
(3) Say that my application is a single executable file like this,
class X{
public static void main(String[]$$$){
System.out.println("Console, where are you?");
At this point, say that my neighbor accepted the two executables, he executed the jre.exe and has jre6 in his system, now he double clicks on my X.jar ... it's a console application and jar files are not associated with the java.exe launcher since java 5, but with javaw which doesn't open any console ... how do i make it so a console opens and prints "Console, where are you?" ... do I ask my neighbor-customer to add a couple of lines to his path and open his console and (please) enter java -jar jarfile.jar? ... isn't it too much? ... i hope i'm wrong cause this is kind of discouraging
(4) I've read that by installing a more recent version of a jre on a system that has an older jre (there to help other applications work), I might be causing a problem for the other applications to run ... I guess that's the reason why that Readme kind of encourage to redistribute a "private" version of a jre (one that doesn't come with a java.exe launcher ... any feedback on this?
(5) I'm reading a lot of hype about Java Web Start ... it looks better than the traditional jar/jre deployment ... but setting up a MIME type to *.jnlp, it doesn't come with some free hosting I've checked ... somebody can recommend a free hosting service that allows to set a *.jnlp MIME? (I'll appreciate a suggestion here, cause I would like to test Web Start)... and, anyhow, how you people compare it with the paradigm of the single executable file?.
Thanks. Your feedback is highly appreciated.

...it looks better than the traditional jar/jre deployment ... but setting up a MIME type to .jnlp, it doesn't come with some free hosting I've checked ... OK. You cannot define new mime types, but perhaps the site already has it defined. An easy way to check is to upload 'any old file' that ends in .jnlp and use the [mime type checker|http://pscode.org/mime/] to see what content type it is served as.
..somebody can recommend a free hosting service that allows to set a .jnlp MIME? (I'll appreciate a suggestion here, cause I would like to test Web Start)... I'm pretty sure the Google based sites offer it.

Some question about mdm java api and portal content

Hi Gurus,
I am new to MDM. I am going to develop some web dynpro application using mdm java api.
My question is regarding the relationship between MDM version and NW version:
for example
1.MDM5.5 JAVA api can be deployed to CE 7.11 server?
2.MDM7.1 JAVA API can be deployed to CE 7.11 server? or can only be deployed to CE server.
the same question for the MDM portal content.
the possible dev environment for our company would be:
1.MDM7.1
2.CE7.2(do we need another EP7 server for the UWL?)
Best regards,
John

Hi,
I am using Portal 7.0. MDM version is 7.1.
My problem is ... i am trying to connect WebDynpro (JAVA) to MDM7.1. But am unable to do so. I have a WD Frame in which i have a WD iView and the MDM iView. But i am unable to pass parameters from the WD iView to MDM Item Details iView.
Note:
1. I have deployed MDM JAVA API on NWDS
2. I have specified " * " as a parameter to pass from the URL in the Item Details iView.
Please help.
Every help that i have read talks about CE7.1 but not NW 7.0

Some questions about the integration between BIEE and EBS

Hi, dear,
I'm a new bie of BIEE. In these days, have a look about BIEE architecture and the BIEE components. In the next project, there are some work about BIEE development based on EBS application. I have some questions about the integration :
1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?
could anyone give some guide for me? I'm very appreciated if you can also give any other information.
Thanks in advance.

1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?You, shud consider OBI Application here which uses OBIEE as a reporting tool with different pre-built modules. Both 10g & 11g comes with different versions of BI apps which supports sources like Siebel CRM, EBS, Peoplesoft, JD Edwards etc..
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?Its independent of any soure. This is OBIEE modeling to create RPD with all the layers. If you build it from scratch then you will require to create all the layers else if BI Apps is used then you will get pre-built RPD along with other pre-built components.
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?BI apps comes with pre-built ETL mapping to use with the tools majorly with Informatica. Only BI Apps 7.9.5.2 comes with ODI but oracle has plans to have only ODI for any further releases.
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?User will still see old data because its good to turn on Cache and purge it after every load.

Some questions about javacard 2.1.1 and smartcardio

Hello i have some question about java card 2.1.1 and the smartcardio package.
1.) I want to sign a message with the Signature.ALG_RSA_SHA_PKCS1 algorithm. I use the following code in the applet to sign the message:
final static byte P1_CREATION_MODE = (byte) 0x01;
final static byte INS_SIGN_MODE = (byte) 0x60;
final static byte SmartCard_CLA = (byte) 0xB0;
private void signMessage(APDU apdu) {
        byte[] buffer = apdu.getBuffer();
        byte byteRead = (byte) (apdu.setIncomingAndReceive());
        signature.init(privateKey, Signature.MODE_SIGN);
        short length = signature.sign(buffer, ISO7816.OFFSET_CDATA, byteRead, buffer, (short) 0);
        apdu.setOutgoingLength((short) length);
        apdu.sendBytesLong(buffer, (short) ISO7816.OFFSET_CDATA, (short) length);
        apdu.setOutgoing();
    }On the host side I use the following code to connect to the card and to send the sign apdu:
if (TerminalFactory.getDefault().terminals().list().size() == 0) {
            LOGGER.log(Level.SEVERE, "No reader present");
            throw new NoSuchCardReader();
        /* Select the first terminal*/
        CardTerminal terminal = TerminalFactory.getDefault().terminals().list().get(0);
        /* Is a card present? */
        if (!terminal.isCardPresent()) {
            LOGGER.log(Level.SEVERE, "No Card present!");
            throw new NoSuchCard();
        /* Set the card protocol */
     Card card = terminal.connect("*");
        ATR atr = card.getATR();
        LOGGER.fine(getHexString(atr.getBytes()));
        LOGGER.fine(getHexString(atr.getHistoricalBytes()));
        CardChannel channel = card.getBasicChannel();
        CommandAPDU cmd = new CommandAPDU((byte) 0xb0, (byte) 0x60, (byte) 0x01, (byte) 0x00, new String("datadatdatadata").getBytes(), (byte) 0x40);
     ResponseAPDU response = channel.transmit(cmd);
        card.disconnect(false);But this does not work and i got the following error

I want to use the 3Des algorithm to encrypt my data. I use
keyDES = (DESKey) KeyBuilder.buildKey(KeyBuilder.TYPE_DES,
                    KeyBuilder.LENGTH_DES3_2KEY, false);
cipherDES = Cipher.getInstance(Cipher.ALG_DES_CBC_ISO9797_M2, false);But i do not know what is the aquivalent on the host side??
3.) Another problem is that i am not able to send the modulus of a public key from the host applikation to the smard card
new CommandAPDU((byte) 0xb0, (byte) 0x20, (byte) 0x01, (byte) 0x00, modulus.toByteArray()); // create the apdu
// the method in the applet
private void setServerKeyMod(APDU apdu) {
        byte[] buffer = apdu.getBuffer();
        try {
            byte byteRead = (byte) (apdu.setIncomingAndReceive());
            short off = ISO7816.OFFSET_CDATA;
            // strip of any integer padding
            if (buffer[off] == 0) {
                off++;
                byteRead--;
            publicKeyServer.setModulus(buffer, off, byteRead);
        } catch (APDUException ex) {
            ISOException.throwIt((short) (SW_APDU_EXCEPTION + ex.getReason()));
    }The error code is 6700
4.) My last problem ist, that i am not able to use a value bigger than 0x7F as the ne field in the apducommand, because i get the following error
CommandAPDU((byte) 0xb0, (byte) 0x60, (byte) 0x01, (byte) 0x00, data, (byte) 0xff);
java.lang.IllegalArgumentException: ne must not be negative
        at javax.smartcardio.CommandAPDU.<init>(CommandAPDU.java:371)
        at javax.smartcardio.CommandAPDU.<init>(CommandAPDU.java:252)I thought that it this should be possible in order to use all the bytes of the response apdu.
If you need more code to help please let me know.
Cheers

2) What is PKCS? what is the difference between
PKCS#11 and PKCS#15??PKCS is the abbreviation of "Public-Key Cryptography Standards"
PKCS #11: Cryptographic Token Interface Standard
See http://www.rsasecurity.com/rsalabs/node.asp?id=2133
PKCS #15: Cryptographic Token Information Format Standard
http://www.rsasecurity.com/rsalabs/node.asp?id=2141
If you want to use yor smartcard as secure token it doesn't have to be a JavaCard.
BTW: I don't remember a way to access PKCS#15 tokens on a JavaCard from within an oncard JavaCard program. If you want to use keys in your oncard program, you have to transfer it onto the card or generate it oncard and export the public key by your own oncard/offcard code.

Some question about fade in // fade out by hideEffect and showEffect in Actionscript

Some question about fade in // fade out by hideEffect and
showEffect in Actionscript
Please kindly take a look at the following page:
http://camusmiu.no-ip.com/HounganQuestion/PictureHolderTest.html
(can view source)
I tried to make an image preloaded and scale the image to
it's preferred size.
When I came to consolidate the stuff into a component, I
found the application goes weird as I implementation the show/hide
effect.
The third trial which just hide and show the images directly,
instead of using viewstack, fail to bring the second image onto
screen.
It just used fadeOut instead of fadeIn(you see there is a
flash of the second image)
After some study of showEffect and hideEffect behaviour,
seems the mechanism of hide/show a component works in this way:
this._fadeIn:Fade = new Fade();
this._fadeIn.alphaFrom = 0;
this._fadeIn.alphaTo = 1;
this._fadeIn.duration = 1000;
this._fadeOut:Fade = new Fade();
this._fadeOut.alphaFrom = 1;
this._fadeOut.alphaTo = 0;
this._fadeOut.duration = 1000;
Component_A.visible = true;
Component_A.setStyle("showEffect", this._fadeIn);
Component_A.setStyle("hideEffect", this._fadeOut);
then when I set Component_A.visible = false, the sequence
works like following:
Component_A.visible = true
Component_A.visible = true, alpha = 100;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 0;
Component_A.visible = false;
The above sequence works visa versa as:
Component_A.visible = false;
Component_A.visible = true, alpha = 0;
Component_A.visible = true, alpha = 50;
Component_A.visible = true, alpha = 100;
Component_A.visible = true;
(Correct me if i am wrong)
========================================================================================== ====
From what I observe from the application, I have two
question.
1) When more than one component using the this._fadeIn,
this_fadeOut as the hide/show effects, the component in instance of
this._fadeIn? will it mess out if more than one component using the
fadeIn instance in the same time?
2) from the third component, i.e. PictureHolder3, when I load
other the picture , it fade out the new image instead of fading
in... Seems there is problem if I hide show too frequent. I think
when I hide then show right the way, the component only do the hide
part...
Can someone pls look into it and tell me what I did wrong?
Cuz in normal practice I don't think appropriate to use ViewStack
in Actionscript...

Hello Jack,
Currently, you can only import an swf file or you can embed videos from youtube, vimeo etc. into Muse / add HTML5 Video to Your Website.
Take a look at these simple videos that explain the currently available processes for adding videos in Muse, in a step by step method:

Questions about JVC GZ HD7 and Final Cut

i'm planning to buy a JVC GZ HD7, but i have some questions about it...
My imac configuration is
Imac 20" late 2006
1 Gb Ram
Leopard 10.5.2
Final Cut Studio 2
Ok
So my questions are:
1- When shooting the best setting for me is the 1440cbr, or 1920x1080
is better? i would like to have progressive instead of interlaced
moviefiles, but for what i have read the JVC HD7 only shoots interlaced...is possible to turn them into progressive after working in final cut?
2- In Final Cut Pro what are the sequence settings and the video
settings for a video shoot from this camera?
I would like to know the best settings possible for me,
regarding that i would like to edit in real time, no rendering needed,
and to have the best image quality that this camera can offer...

FCE is designed to work with DV/HDV files. It cannot work natively with MPEG2 files. You will need something like MPEG Streamclip to convert your files to a format that FCE understands
Streamclip is free but you need to buy Apple's MPEG Playback Component to make it work

I need some advice about the macbook pro and iPhone 5.
I took a video on my iPhone and tried to email it it said it was too big to send? So i downloaded it to my macbook pro and tried to mail it to no avail? The macbook tells me the server won't let it through other mail goes through any ideas how to resize it or what it might take to send it?

I agree with LowLister, the best option for you to share the video online is to upload it to your online storage account for example : Box, Dropbox, SkyDrive (All of them provide free storage beginning from 2GB).
You can upload the files which you want to share in this online storage and then they have sharing options in which you'll will get the link of the file to be sent and send the email. You're good to go!
Tip : You can store multiple files for backup purposes.

I need some information about jre 1.5 and jre 1.6.

Hello guys,
I need some information about jre 1.5 and jre 1.6.
Suppose if i have jre 1.5 customized with "additional language support" installed in my my desktop, and later on i install jre 1.6. will this jre over write all the esisting settings which was present in jre 1.5?
In short will the version upgrades disable the features of the old Version even though the old version is present in the desktop?
Thanks in advance for your answers.

^^^^^^ ^^^^^^ ^^^^^^^ ^^
That's not a trivial step. I would write a small C/C++ program that
exercises your driver (for robustness) just to be sure it's working
right first without crashing your system.
>The problem is that I don't know to use this driver in LabView.

That's correct. _After_ you got your C/C
++ test program (and USB
driver) above working, then you can convert this little test program
into a DLL or CIN, which can interface with LabView. A DLL might be
easier (slightly) to write, but the CIN will work faster with LabView
and can be designed to be reentrant. The Code Interface Reference
Manual should guide you. Remember, this is a task for an _experienced_
C programmer. You'll need to use handles to pointers into all your
dynamic arrays and such passed into LabView.
After you got your CIN or DLL written, you can use a special CIN
function node to "link" (or bind) your CIN object into LabView's VI
diagram.
SOME THOUGHTS:
There are many hardware devices already on the market today that come
with Windows 98 drivers and DLL (or even CIN) libraries that would work
immediately with LabView. Why don't you save yourself three months of
work and simply buy one of these?

Some questions about configuration in MAX.

Hello,everyone!
I have some questions about configuration in MAX(I am a jackaroo for motion control development),I hope I can get your help.
I use PCI-7344+UMI-7764+Servo amplifier+Servo motor,my MAX version is 4.2 and I use NI-Motion7.5
My question as following:
1,In Axis Configuration,for motor type,why I must select stepper but not servo?my motor is servo motor!If I select Servo,my motor can't run,I don't know why.
If I select stepper,though motor can work but I can't test encoder in MAX.
2,In Stepper settings,for stepper loop mode,why I must select open-loop but not close-loop?If I select close-loop,the servo motor doesn't work too.
3,If I want my two servo motors run at different velocity,How shoud I do?It seems I just can set the same velocity in MAX for my two servo motors.
My English is poor,Pls pardon me!I come from China.
Thank you for your help!

Hi,Jochen,
Thank you for your kindly help!
The manufacturer of the drive and motor that I am using now is Japan SANYO DENKI,drive type is RS1A01AA,motor type is R2AA06020FXP00.
And I use position control mode,thehe encoder's counts per revolution is 131072.I set the electronic gear ratio to 1:1 for drive.
Now,I can use Close-Loop to control the motor but still has some problems.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.When I configure it to run in closed loop mode, the motors behave strangely and never move to the target position.The detail situation is as following
1,Motor can't run.
2, Or motor moves to a position, then moves in the same direction agian and eventually stops.
Except for the two points mentioned above,"Following Error" is occured frequently,I don't know why.
I am still not clear why I must set the motor type be stepper in MAX .
And I have another question:what the relationship between the steps and the counts?They have the proportion relations?I notice that there are a section said like this in help document: For proper closed-loop and p-command operation, steps per revolution/counts per revolution must be in the range of 1/32,767 < steps/counts < 32,767. An incorrect counts to steps ratio can result in failure to reach the target position and erroneous closed-loop stepper operation.
I am verry sorry I have too many questions!
I am very appreciate for your kingly help!Thanks again!

Hello ,
I want to ask some question about ipads \
How powerful is the iPad?
How useful is it for reading books, newspaper or magazines or for surfing the web?
Can you identify any shortcomings of the device?
please help me

it's less powerful than your average computer. THink of it like a netbook but with a better processor.
It'll do fine for surfing (although if you browse a lot of flash based sites you will need to get a third party browser since safari doesn't accommodate it)
You may do OK on reading books, papers or magazines, especially if they have apps, but the ipad's screen is backlit, so it doesn't work well outdoors and you may need to fiddle with the brightness so that you don't get eye strain (it's just like doing too much reading from a computer screen)
I would say the biggest short comings are data transfer. Apple's preferred work flow is that everything is done via iTunes or the internet....well people dont' always have 100% reliable always on internet access so you can find yourself in a situation where you can't get things on/off the iPad.
By and large, it's a good device for day to day stuff, but is not a computer replacement.

Some question about flex and facebook, and saving server work!
