Calculate the time remaining during File Download ?

Hi
I need to calculate the time remaining of file download . I am using NSURLConnection for file download in Cocoa . I am able to show the download progressbar . I want to show the time remaining for complete download and it should vary if network signal fluctuate .
Please guide me ...
Thanks

The tricky part is to define what is a disturbance
First do once a correlation to find and correct a shift in the signal
Look at the (absolute or squared) difference of both signals and define a threswhold and use the threshold detector vi
from the point location(s) calculate the time and log it.
And have a look at the waveform monitoring vis....

It appears that the time remaining calculation is hindering the download.

So I'm trying to download a 2GB movie on a slow DSL connection. I understand it's going to take a while, BUT...
Why does iTunes try and recalculate the time remaining after 1k of download? Each time it recalcs, it slows down the download. I wait for recalc, then another 1k gets added and it recalcs. What a waste of processing time.
Here's the interesting part. If I pause the download then restart it, bang! I get 1k more instantly. Now if I sit here and pause/start/pause/start/pause/... you get the idea, I can download it faster than just letting it do it's dumb calculation.
Help! Can I turn off the calculation?
Thanks

I agree, there is something strange. I am just downloading an update for my ipad and can see what you are saying.
I also experienced this sort of problem much worse when converting aac to mp3's.
If you stay on the page where you selected the music and start the conversion you can see the progress bar and it goes like a snail with someone standing on it. If you swap to another page where you can't see the progress bar it all speeds up amazingly.
That's life

I have purchased two movies on the store that at the time were unable to download, due to a full start up disc. I have now freed up the space and the remainder of the movies wont download. It gives me the error code 8003. I have a good network connection.

It doesnt even let me delete the downloads and start again.

1. iTunes won't offer cloud downloads for songs that it "thinks" are in your library, even if it "knows" the files are missing. If you've exhaustively searched for the missing files and there is no prospect of repair by restoring to them to their original locations, or connecting to new ones, then delete that tracks that display both the missing exclamation mark and are of media kind Purchased/Protected AAC audio file. Don't hide from iTunes in the cloud when asked, close iTunes, then reopen. You can download from the cloud links or iTunes Store > Quicklinks > Purchased > Music > Not on this computer > All songs > Download all.
2. Why? Not sure, perhaps 3rd party tools or accidental key presses combined with previously hidden warning messages when trying to organize the library. There is a hint that using the feature to downsample media as it is synced to a device may also be involved, though I've not replicated it. Whatever the reason a backup would protect your media.

Why is the time remaining going up as I install adobe inDesign through creative cloud?

Why is the time remaining going up as I install adobe inDesign through creative cloud?

Downloads have built-in "checksums" (I think that's the correct term that basically check to make sure the bits of data are being downloaded correctly.
Sometimes the previous check has to redownload the previous bits. That can cause the time to go up.
Also, it may be that your bandwidth speed is slowing down or lots of others are accessing the bandwidth.
BUT if the download goes way, way up—like instead of 12 minutes, it goes to 6 hours, something's wrong with the installation.

What does negative time remaining mean in downloading Mac OS X?

what does negative time remaining mean in downloading Mac OS X?

Thank you very much, Andy Z. Your reply is very encouraging. The negative time is already at -28 hours !!! Still hanging on after 48 hours online and impatiently installing the mac os x to fix the gray spinning gear on the screen. Thanks again.

Why is the time remaining so wrong?

I've noticed over the past few years that the "Time Remaining" estimates from various applications in OS X are increasingly inaccurate - usually the estimate is too long!
This is true for apps from Itunes, to Disk Utility, to <on and on and on>. For example, I was just burning a DVD from a playlist in ITunes and when it started the "Finishing" part - it said "Might be up to an hour". It completed in 30 seconds.
Time estimates are just that - estimates - but do they have to be so wildly inaccurate as to be useless as a guide? I have a feeling nobody in the OS X world has looked at how they update the estimate in a long time, and they do not presently reflect the performance of either hardware or software.
Hey Apple! Update the Time Remaining code! Please?

Ignoring the boot progress bar (which I believe is an animation, at least it was in my old Tiger system), the progress bars are usually computed by specifying a range of values to produce a scaling factor and updated by supplying values within that range. The amount of progress is determined by the supplied values within the range.
The segment of code responsible for supplying values is given control on some criteria within the algorithm doing whatever the progress is to measure. There's potentially a lot of variables that can affect when this segment of code is called to update its progress. With disk copies there's how fast the drives are, buffer sizes, what else is running that could interrupt the process, and who knows what else. Certainly you should not expect the progress bar drawing to have a high priority in the grand scheme of things. I'd rather the service be "obsessed" with its primary goal (whatever its service is to do) rather then keeping me constantly updated every millisecond taking valuable cycles from the primary task.

When watching an item ending in ebay/firefox, the time remaining doesn't count down.

When watching an item ending in ebay/firefox, the time remaining doesn't count down. However I'm sure it used too.

Just an update...
I took my computer into the Apple Store and they gave me a new battery (again). I also erased my hard drive and reinstalled Lion. I am still having the same problem with my battery icon not counting down (when i have the power cord unplugged). Another thing I may have not talked about is when I unplug my power adapter from my MacBook the screen used to dim slightly, It no longer does that. Hmm. And yes I have checked the power settings.
I am seeing a big difference in my new battery though. The 6 month old battery I was using before my replacement wasn't lasting but maybe and hour before completely turning off my laptop. SInce I got my replacement battery I am back to a regular battery life. Maybe a couple issues going on here...
As a fix, I purchased Battery Guard from the app store and placed the icon on my tool bar. It actually counts down my battery life as a percentage. So its a huge help. I just don't know why the native Mac icon isn't working properly?? One thing I have noticed is the 3rd party app will only count down using a Percentage. But, like the native Mac icon it will not count down using time. Something else to add... After using my battery, and I plug my MacBook back in, the battery icon will count up. Kinda strange that it will count up but not down.
Dstppy, any luck at the Apple Store?

I am running with Firefox version 3.5.7. I am trying to update to a more recent version. So far, the update has been running for 4 hours. For most of the time it has been downloading versoin 3.6.18. Why am I hanging trying toi update?

I have an old version of Firefox - Version 3.5.7.
I am trying to update to the current version. As part of the update, the system is first loading all of the intermediate versions.
I started the update 4 hours ago. It is still running. Most of the time, it has been downloading version 3.6.18. I am letting it run.
Is there any other way to get the most recent version?

Thank you. That is basically what I did. I gave up on the update and downloaded a fresh version of Firefox.

Need the query to calculate the time taken to excute it.

hi all,
i need the query to calculate the time taken to excute it.
for ex:
select * from emp;
how much time it will take to give o/p
Thanks in advance
satya

Just to add to what was said - the execution can each time be DIFFERENT as the factors that governs performance are NOT CONSTANT.
If Oracle has no idea how long the query is going to take before executing it, then how can you and your code know?
Oracle's CBO estimates the cost (expense) of the query. This is an indication of how expensive a query is - and the more expensive the query, the more resources need to be used, the longer the query will take. The less expensive the query, the fewer resources it need, the faster it will take.
And that is it. How fast or how slow? Oracle does not know. How much faster a query with a cost of 10,000 versus a query with a cost of 1? Oracle does not know.
Why? Because the platform is not constant. Just what data is at this exact moment in the db buffer cache? Just how much CPU capacity is available for the new few seconds? Just what will the sustained throughput be of the I/O subsystem and channels for the next minute? Just how many memory pages need to be swapped between cache and memory? Etc. etc.
All these factors change every single second. So forget about attempting to accurately calculate up-front the time it will take for a query. IT IS NOT POSSIBLE.

How to calculate the time between start trigger,first scan and first A/D in DAQ

Environment: Labview 6.1, N6052E DAQ board(max scan rate=333KHz, max channel rate=333KHz, settling time=3.5usec+1LSB)
I am using external scan clock 10K scan/s collecting data on 16 AI channels, and external channel clock 200KHz.
Could show me how to calculate the time betweent he start trigger, the first scan and the first A/D conversion?
Thanks

I read the one you give to me. still cannot work out. I am using Labview 6.1 DAQ vi, including AI config.vi. clock config.vi, AI control.vi, AI read.vi, working on colect data on 16 AI channels. So I belong to SCAN function and external scan and sampling timing, right?
But it says the T1 and T2 are determined by external signals. How can I calculate that?
T1=1/10KHz or T1=1/160Khz?
T2=1/200KHz?
Is the above correct?

Were you migrating from a Time Machine backup or via WiFi, ethernet, or Firewire?

How to Calculate the Time Between two days in ABAP

Hi,
              I have one scenario like i need to calculate the time between two days please can you suggest me.
Thanks,
Harinath

Hi Peeleti,
            Check this code,
DATA : DATE1 LIKE SY-DATUM VALUE '19830125',
       DATE2 LIKE SY-DATUM VALUE '20070219',
       DAYS1 TYPE I,
       WEEK1 TYPE I,
       MONTH1 TYPE I,
       YEAR1 TYPE I,
       C_YEARS1 TYPE I.
CALL FUNCTION 'HR_99S_INTERVAL_BETWEEN_DATES'
EXPORTING
BEGDA           = DATE1
   endda           = DATE2
TAB_MODE        = ' '
IMPORTING
DAYS            = DAYS1
C_WEEKS         =
C_MONTHS        = C_YEARS1
C_YEARS         = C_YEARS1
WEEKS           = WEEK1
MONTHS          = MONTH1
YEARS           = YEAR1.
D_MONTHS        =
MONTH_TAB       =
*WRITE : / 'DAYS   = ', DAYS1,
        / 'WEEKS = ',WEEK1,
      / 'MONTHS = ', MONTH1,
      / 'YEARS   = ', YEAR1.
Using this code you can calculate the No Of Days Between two dates. Based On days you will easily calculate the Hour. [ No of days * 24 ].
Thanks.

Calculate the time spent to execute your program

Hi
I have a pgm which calculates the response time in milllisecond using method System.currentTimeMillis(). And I get answer 0.
My question is If we measure the time in terms of nanosecond, do you think we still get zero answer?and What is your explanation for that?
Waiting for reply. Thanks in Advance
Regards,
Jyoti

Hi,
Here is the code for calculating the response time.
public class RunLinkedEvenOddList {
     public static void main(String[] args) {
          long time1;
          long time2;
          time1 = System.currentTimeMillis();
          System.out.println("Program 2 output:");
LinkedEvenOddList eolist = new
ew LinkedEvenOddList();
          eolist.insert(9);
          eolist.insert(4);
          eolist.insert(3);
          eolist.insert(2);
          eolist.insert(5);
          eolist.print();
          System.out.println("print Even:");
          eolist.printEven();
          System.out.println("print Odd:");
          eolist.printOdd();
          eolist.delete(9);
          eolist.delete(1);
          System.out.println("list after delete 9, 1:");
          eolist.print();
          System.out.print("execute isMemeber(3): ");
          System.out.println(eolist.isMember(3));
          time2 = System.currentTimeMillis();
System.out.println("The starting time: " + time1 +
+
                    " milli seconds.");
          System.out.println("The ending time: " + time2 +
                    " milli seconds.");
Answer the following questions based on the output of
your code:
1. Calculate the time spent to execute your program
based on the value of time1 and time2; you need write
your formula first and then give the answer in
millisecond.
Answer:
time2-time1
time spent to execute your program = 0 millisec
2. If we measure the time in terms of nanosecond, do
you think we still get zero answer?
Answer:
3.What is your explanation for that?
Answer:
Pls help me in answering question 2 and 3. Thanks in
advance.Hai Ram!

I need to get the elapased hours between these two columns. Please help me
Thanks

you can use beans or create a case when statement like:
case
when TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) <= 60 then 1 else
when TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) > 60 and TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) <= 90 then 1.5 else
when TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) > 90 and TimeStampDiff(SQL_TSI_Min, table.column1, table.column2 ) <= 150 then 2.5 else
end

Why is the Time remaining not showing up screen?

When listening to music the time remaining doesn't show up on the screen. It does show up on my iPhone 4S but not iPod Touch.Why is that?

Because you need to tap the Now Playing screen so that the time scrubber bar is overlayed onto the artwork.
