Wait for the digital signal

Is there like "wait for the panel activity" in digital signal, "wait for the digital signal goes up" etc. ?
Or is it bad to make it with sequence structure and inside of first sequence use while loop?

If you need to wait for a digital signal before continuing on with your program, the best way is to have a while loop that continuously reads the signal and stops the loop when the signal goes high. You can put this loop in the first frame of a sequence, or you can wire an output from the loop (like error out from the device read vi) into your next step. Be sure to put a delay (100mSec) in your loop so that the loop does not hog CPU time.

Should You Buy An iPhone Now, Or Wait For The Next One?

Great article by HuffPost Tech.
The most common thing I get asked whenever I tell anyone I'm a tech writer is some version of the question: "Should I get a new iPhone now, or should I wait until the next one comes out?" It is as though my business card should read not "Technology Writer," and instead "iPhone Psychic"
Not that I am not happy to prognosticate! And in that spirit, here's a look at the questions on everyone's mind: Should I buy an iPhone now? And if not now, when?
First, let me say that I am fascinated by the peculiar kind of panic that I encounter in people I meet who are deciding on a purchase date for their next Apple phone. I call it the iSenberg Uncertainty Principle: Potential iPhone buyers exist in a constant state of anxiety, perpetually worrying that purchasing an iPhone on any given day will mean that they will miss out on the inevitably cooler version with the mind-blowing new features soon down the road. The Cupertino Sword of Damocles constantly dangles over their heads, threatening to pierce them with unhipness and iShame.
Here is one solid piece of advice I can offer to help you avoid the Sword: Do not buy any new iPhone until September. Apple has an annual media conference each September, and every blog with the word 'Mac' in the title is reporting that Steve Jobs is going to do his black turtleneck thing and introduce some kind of new iPhone there. The September Media conference is generally used to present the new iPods, but as All Things Digital reports, Apple plans to "commandeer" the conference for its official iPhone announcement.
Apple is long overdue to release its new iPhone anyway, if history is any indication. Look at this handy little timeline:
June 2007: original iPhone released
June 2008: iPhone 3G released
June 2009: iPhone 3Gs released
June 2010: iPhone 4 released
June 2011: Nothing!
In other words, the 5th generation iPhone is already a month late, so it makes sense that the rumors are swirling. Apple's tardiness can be explained by the fact they've actually already released two iPhones in 2011 -- the Verizon iPhone in February and the unlocked iPhone 4 in June. Their schedule is all screwy, like a traveler trying to get over jet lag. But all signs point to them getting right with a September Apple iPhone release.
So what jaw-dropping new feature will this iPhone boast? We're hearing that the "iPhone 4S," as it is rumored to be called, won't be the dramatic re-imagining that many of us have come to expect with each new iPhone release. Tech blogThis Is My Next thinks that it will be thinner and lighter, and that it will run on a new chip; the New York Times thinks that it will be the same dimensions as the iPhone 4 but that it will be cheaper. Bloomberg agrees with This Is My Next on the chip and adds that the rear-facing camera will upgrade to 8 megapixels from 5 megapixels.
Now, even if you're just a normal, non-geek iPhone user, who doesn't care if the rear-facing camera doubles its megapixel count, or if Apple has changed the manufacturer of its data processors, or whatever, you still need to at least wait for the alleged iPhone announcement, and here's why: if history is any indicator, the introduction of a newer iPhone model is accompanied by a drop in price of older iPhone models. When the iPhone 3GS was announced, the price of the iPhone 3G dropped by $100; when the iPhone 4 was announced, the price of an iPhone 3GS also dropped by $100. Even if you know that you're not going to drop $400 on whatever iPhone Apple begins peddling in September, there is no sense in paying more money for an iPhone 4 or 3Gs now when the base price of both seem like locks to drop in two months.
But before we start fantasizing, how can we be so certain that Jobs is even going to announce an iPhone in September if Apple hasn't so much as indicated such a thing? How do we know that all of these rumors weren't just started by lonely nerds like me and my co-workers emailing each other from our mother's basements, inciting iPhone rumors all on our own?
Well, first of all, I don't live with my mother; and second of all, the new iPhone rumors have sprung forth from two reliable sources held in high journalistic regard.
The first is esteemed, award-winning tech journalist John Paczkowski of All Things Digital, who blazed iPhone prognostication trails by predicting back in April that an updated iPhone 4 would be unveiled at the September Apple music Conference and has steadfastly maintained the claim is true through June and into July. In fact, he confirmed as recently as July 5 that a shiny new iPhone looked to be in the early stages of supply chain production, and that people close to the company still believe that the new iPhone would be ready for the Jobs treatment in September.
So there is Reliable Source One.
Reliable Source Number Two is the Wall Street Journal, not exactly a one-laptop operation. The paper gives "the end of September" as a target launch date, which squares up with both Paczkowski's prediction of a September announcement and release. This doesn't even mention This Is My Next's separate prediction of a September release, nor 9to5Mac reporting that there are going to be two new iPhones in September, one low-end and high-end. But now we're falling down the rabbit hole and into the basement again, so let's focus:
There is likely to be a new iPhone in September. It will likely affect the price of all the other iPhones. The iPhones available now -- the iPhone 4 and the iPhone 3Gs -- will probably be cheaper in two months. Unless you drop your current iPhone in a pool, a bathtub or a volcano, do not buy an iPhone until Steve Jobs opens his beautiful brilliant mouth at the Apple conference in early September. When the post-turtleneckian dust settles, we'll have a clearer picture of whether or not this rumored new iPhone is worth the money. And then we can talk about--well, whether or not you should buy an iPhone now, or wait until the next one comes out.
http://www.huffingtonpost.com/2011/07/12/iphone-release-5-september_n_896345.html

Apple has two prototypes out testing now. One is a thinner totally redesigned case. The problem with it is that Foxconn can't seem to build it. Hence the delay. The other prototype uses the existing case, but with updated (read dual core) internals. If they can get production up by September the first phone will be released and will be the iPhone 5. If they cannot, then the second prototype will be released as the iPhone 4GS.

How to wait for a digital input to go high?

I bet the following question is explained somewhere but I don't know how to find it.
Is there an optimal way to wait for a digital input to transition from 0 to 1? I mean, other than creating a loop that continously polls the input line is there a better way to wait for the transition? With all the "event driven" capability of CVI I suspect there's a slick way to do this but I don't know how to find it. I'm willing to RTFM if I know where to look.
thanks

Hi,
I have never done this, but it looks like it is possible to use the DAQmxRegisterSignalEvent function to assign a function that will be called when a "change detection event" occurs.
It works on a task basis, so if I'm not mistaken, you need to put the digital to be tracked into a separate task.
It is not stated if all NI hardware is compatible with this functionality, so try and see if it works for you.
Hope this helps,
Edit: It looks like you have already found the solution by yourself

Waiting for the end of the process

I'm executing a command using the Runtime class and I have to wait until the end of the command to get the results. But, I don't want to sleep the thread for some undeterminated time. I'd like it just to wait until the command ends.
See in this code:
try
String result="";
Process p = Runtime.getRuntime().exec("sh"); //open a new shell
InputStream is = p.getInputStream();
OutputStream os = p.getOutputStream();
os.write("ifconfig -a | grep PROMISC -c\n".getBytes());
os.flush();
try {
Thread.currentThread().sleep(1000);
/*command should take some time to execute so wait for 10 secs .... I don't like this .... I would prefer waiting for the end the command ifconfig*/
catch (InterruptedException eIE) { }
while (is.available() > 0)
result = result + ( (char) is.read());
System.out.println(result);
catch (IOException e) {
System.out.println(e);

AFAIK you can only detect if the shell process has finished, as sub-processes of the shell are not visible to your Java program (without resorting to OS-specific syscalls).
You can write "exit" (or whatever terminates your shell) in the output stream as the last command - this will quit the shell as soon as all commands are finished, and that will be visible to your prog. Note that you should not run ANY of the shell commands in background then, as this could cause the shell to exit before the commands are finished (and, depending on the system, even signal the subprocesses).

Waiting for western digital

Hi all,
I recently added a 500GB western digital 'my book' to my set up.
The question I want to ask is, why is it that whenever I try to do anything such as opening an app or file I have to wait for the 'my book' to power up before I can get started. It's obviously powered down when not in use but its as though the whole system has to wait until this thing starts up again before responding. I presume I'm using the correct description when saying 'powered down/up'. If its not been running for a while it'll make the noise of a drive starting up anytime there is an activity required, this doesnt mean accessing anything off the drive either. It'll do this if I'm accessing data from one of the partitions too.
I've looked in the startup items to see if theres anything obvious there but cant see anything.
I have had another external hard drive prior to this and that never interfered with the running of my mac. Is it possible something has been installed during the intitial setup. It's connected via firewire BTW

If it has a special driver, it would have been installed by you (running a package or installer program) and you would know about it. A drive cannot automatically install something on your Mac without your knowledge. If something needs to get installed in your System (which would be necessary for a driver to be active), Mac OS X takes the additional precaution of asking for admin user authentication before proceeding.
Take a look at the manual. The drive may have special features that are enabled or disable using switches on the back of the drive.
Another possibility is formatting. If the drive was never re-formatted for use with a Mac, it may be FAT32 format. That could slow things down.

How do I call the subvi in parallel with main VI. Main vi should not wait for the subvi

I have a subvi which takes the parameters like port name, transmit rate, message to transmit over serial port and Start/stop flag. This subvi calls VISA write vi in a loop continuously, till the Start/Stop flag is false, to write a message to serial port at a mentioned transmit rate. This subvi will be called from another VI. Actual intension is to transmit different messages to different ports continuously and stop them when required. In this senario, please provide solution for below points:
1. How do I call the subvi in parallel with main VI. Main vi should not wait for the subvi.
2. How does main vi can control already running subvi in parallel to it. In the above example I would like to start the subvi from main vi when start\stop flag is true and would like to stop it when the flag is false.
3. How do I call the subVI with one set of parameters from main vi, when same subVI is running with other set of parameters already from main vi(subvi being called in a case with different set of parameters each time when the case is called). Means, how do I keep track of reentrant subvi (different calls to same vi)from the same main vi.

Faxing does not work. Says it's waiting for the driver to connect.

I set up the bluetooth fax printer but when I click to send the fax, it says that it's waiting for the driver to connect.
Any ideas?

If you don't have a land line you can't fax without a system like eFax which uses e-mail to send faxes to a phone number. If you have a land line, you must tie up the land line to connect to another phone number to Fax to it.
You can probably also fax over VOIP based lines, but not all have a strong enough signal for faxing. Check with your VOIP carrier if you have one if Faxes are supported. Regardless, the Fax capability of any multifunction printer or scanner is only operable through an actual phone line. VOIP offers phone line to internet capability.

I ordered a battery for my laptop because it said to replace battery soon. How long can I let the new battery sit around as I wait for the old one to run out of more charge?

I ordered a battery for my laptop because it said to replace battery soon. How long can I let the new battery sit around as I wait for the old one to run out of more charge? Will the new one become less effective if it sits around too long?

How much capacity is remaining on your current battery?
Check your power status
From the  menu: Hold OPTION and click System Information... èHardware è Power
Copy and Paste in your reply.
The new battery will become less effective if you store it in a hot or humid environment. It should be stored at room temperature (22 C).
Long term storage (6 months):
Apple recommends that you store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life.

Try:
- Another cable
- Another USB port
- Reboot the computer
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Please wait for the group policy client - shutting down issues

Hi
I have issues with shutting down machines. When machine is connected to company's LAN everything works fine. However, if machine is connected to VPN - Juniper NC - 1 hour or more it always hangs when it is shutting down. When I shut down the machine
(verbose mode on), first stage is:
Please wait for the system Event Notification service.
This ends exactly
after 3 minutes. Next stage:
Please wait for the group policy client windows 7
...is never timed out (even after few hours). Machine never shuts down.
In Application logs there are always these 4 events when machine is unsuccessfully shutting down:
6005: The winlogon notification subscriber <Sens> is taking long time to handle the notification event (Logoff).
4627: The COM+ Event System timed out attempting to fire the Logoff method on event class {D5978650-5B9F-11D1-8DD2-00AA004ABD5E} for publisher and subscriber . The subscriber failed to respond within 180 seconds.
The display name of the subscription is "ISensLogon2". The HRESULT was 80010002.
6006: The winlogon notification subscriber <Sens> took 180 second(s) to handle the notification event (Logoff).
6005: The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (Logoff).
Sens is timed out after 3 minutes while there is no 6006 event for GPClient and machine is stuck there for ages (Please wait for the group policy client
stage). I noticed in System logs that machine always hangs if there is this error

I tried with signing out from VPN before shutting down machine, I even switched off WiFi but machine still hung. If i tried to get GP results before shutting down machine it takes ages and it is stuck in "Getting the user name" stage.
Gpupdate /force never updates policy (It stops at Updating Policy...). I tired with installing different hotfixes which did not resolve the issue. I never have any
issues with logging in, no GP scripts are applied when user is logging off or on, no roaming profiles. The only issue is when machine needs to be shut down.
I excluded 1 machine from GP and left it on VPN for a few hours, several times. It always shuts down successfully. I applied GP back one by one and the one which is presumably causing an issue is Avecto which adds admin rights when VPN application
starts (event 100):
Process started with admin rights added to token.
Command Line: "C:\Users\User\AppData\Roaming\Juniper Networks\Setup Client\JuniperSetupClient.exe"

I guess there is a DNS issues when machine is on VPN which leads that GP cannot be applied / updated. Not sure if or why Avecto would have an impact on this. When machine is trying to shut down it still somehow thinks it is connected to DC. What
I also noticed are several explorer crashes while machine is on VPN.
Does anyone have same issues? All machines are Dell with Juniper NC (VPN).
Thanks,

Hi,
According to event log, Winlogon process takes a long time to handle logoff event. That's to say winlogon process is waiting for response to logoff.
According to your description after, this problem is most probably caused by Avecto. You can try to disable or uninstall it temporarily for test.
To make further troubleshoot with this problem, you can try to use WPT (Windows Performance Tool) to make troubleshoot.

Windows 7 very slow logon, Waiting for the User Profile Service, winlogon event 6006

Hello,
Every so often one of our Windows 7 clients which is not normally having any delay at logon will take a very long time to login. This may be 10 or 20 minutes or up to an hour in some cases.
Typically the event log will contain entries like
The winlogon notification subscriber <Profiles> took 572 second(s) to handle the notification event (Logon).
There is no further information available from Event Log Online Help, nor any additional detail as to why the logon event was so slow. During the delay the user will just see "Waiting for the User Profile Service" on their screen.
We first started seeing this problem with Windows Vista and if anything the situation has not improved since then. It has never happened with any of our Windows XP users.
We are currently planning a migration of computers to Windows 7 but stuff like this which has not been resolved in Windows over a 2 year period will stall that migration. The least improvement is to increase the event notification to give a lot more
information on why the user profile processing has stalled.

Hi,
When did the issue begin to occur? Did it occur after installing certain application or applying certain policy?
To troubleshoot the issue, please perform the following step.
1. Restart the machine in Safe Mode with Networking to check whether the system can login quicker.
2. Type “gpedit.msc” in Search box and press Enter. Navigate to the following location:
Computer Configuration->Administrative Templates->System->Logon
Please double click “Always wait for the network at computer startup and logon” policy and disable it.
3. Perform a
Clean Boot to check the result.
Thanks,
Novak

I have two hard drives on my mac 10.5.8 power pc and hear the clickking sounds of the first hard drive and think that it may be dying, can I install everything on the other hard drive also and wait for the first drvie to die before i use the other drives

I have two hard drives on my mac 10.5.8 power pc and hear the clickking sounds of the first hard drive and think that it may be dying, can I install everything on the other hard drive also and wait for the first drive to die before i use the other drives? Or, what is the best way to handle this?

I do not know what you are waiting for.
I'd make a backup of your important stuff before cloning the entire disk.
Carbon Copy Cloner will copy your startup drive to an external firewire drive. You can boot from the external drive to verify that you have a good clone. When you upgrade your existing startup drive, you can at any time boot from your external drive and go back to your existing system.

SuperDuper is the wildly acclaimed program that makes recovery painless, because it makes creating a fully bootable backup painless. Its incredibly clear, friendly interface is understandable, easy to use, and SuperDuper's built-in scheduler makes it trivial to back up automatically. And it runs beautifully on both Intel and Power PC Macs!

Sould i buy the white 4g ipod touch, or wait for the 5g ipod touch?

I have the third generation ipod touch, and i love it but it doesnt have a camera. I was waiting for the fifth generation to come out but instead they released the same model but in white. Now i don't know if i should wait another year to buy the ipod touch which might have new features or just buy the white ipod.
