• convert date julienne in normal date

  Hi all
  
  I use the TO_DATE (TO_CHAR(datecolumn+1900000), 'YYYYDDD') sql query to convert the julian date format to the normal date format
  
  It works fine for all the attributes of date format such as start date, hiredate, deadline except date of birth attribute
  
  I have a date of birth for this same query attribute does not
  
  Can I know the solution

  It seems that your dates are stored as an offset (number) of JAN-00-1900.
  This isn't a Julian date. Julian dates are starting to 01-JAN-4713 BC. Oracle interpreter originally Julian as 01-JAN-4712 BC, probably having to do with non-existent year 0.

  Anyway, you add two numbers, interpreting and converted into character as a date in the form YYYYDDD.
  It will work for a range of 1 to 365. Error ORA-01848 will cause another digit.

  What you need to do instead, is to take your original as a date (which would be 01/01/1900) and add a number of days (minus 1 since your original one is off).

  sql> select to_date('19000101','YYYYMMDD') + datecolumn_which_is_actually_a_number - 1 from dual;
  

  But the real WTF is storing a date in a number instead of a date data type.

• While why broken arrow will not appear for a timed loop

  Hi all

  I need a little clarification relative to normal while loop and timed looping in labview.

  In labview, if I keep a while loop on a block diagram, broken arrow will appear in the upper left corner of the window indicating the error. It displays error because I have not wired conditional terminal of the while loop.

  But same is not the case for a timed loop. Can someone tell me what is the reason behind this...

  If I release the conditional terminal of the timed while loop, it runs in infinfite time like a normal while loop. Then y labview behaves differently for these two types of loops in the scenario above.

  FYI... I'm using labview 2009.

  Waiting for response.

  Thank you

  Ruben,

  the reason is quite simple: call loops are mostly real-time and FPGA targets. Since most of the applications on these targets work continuously (at least this is more often the task), it is possible to create a loop that does not end. So the timed loop by default assumes that there is no need of a stop button.

  The 'normal' while loop needs code for termination (conditional terminal) because normal applications on Windows/Linux/Mac are used to be fair...

  hope this helps,

• Timed loop versus While loop

  Most of the machine control software I design have the following structure:

  1. There's a HAND that takes place inside a TIMED LOOP with synchronization of 50ms and priority of 100. His only job is to read / write data from / to DAQMx IO cards.

  2. the MAJOR can call several SUBs based on the choice of the user, and once a submarine is called FP MAIN is closed and the FP SUB opens. All submarines have a States Queued Machine running within a TIMED LOOP with 50ms timing but with priority to 50.

  3. data transfer between HAND / SUB is through function globals - there are many of them based on past data.

  4. all woks fine so far. No need to any RTOS. and platform of WIN7 is alomost standard. I even ran with a timing of 20ms without anything crashing...

  Problem: When there are a lot of file i/o operations in a SUB partciluar, then I have the chance to see several missed iterations. Perhaps the TIMED LOOP is hogging resources.

  What I want to do: convert both TIMED in asnd SUB HAND loops simple while loops.  But I am concerned by the priority - since the MAIN interacts with HW there priority. But with LOOP WHILE how can I ensure this?

  Or is there any replacement / effective way of doing what I do now?

  .... FGV should be thrown out the window...

  Well used for a while, based on many articles in the KB. One of them is locked... and it does not represent the engine of the Action or of the FGV as a villain to avoid.

  The driving force is one of the largest buildings in LabVIEW.  The FGV who does nothing but Get and Set (or writing and reading) is useless and a waste of resources.  Why?  It does nothing to fix possible race conditions (does not protect critical sections) and it is much slower than just using a global variable.  See this example I put in place to see what I mean: an overview of the race Conditions.

  Rama wrote:

  So in the sample that I had attached, what do you think would happen if I just replaced the two loops with the SAME timed in MAIN and SUB wait value ms. is there a work order then?

  When things are at the same time, there is no such thing as the order of execution.  But as I said, it seems that your loop is quite slow, so it's something I would not worry.  Just make sure that you do not have a loop that uses all the CPU.

• Image Data Converter for Mac rotation loop

  I have the latest version of Image Data Converter for Mac.  Normally I use Lightroom, but I wanted to try this software because it is designed for Sony raw files.

  The software works pretty well on my Mac Pro 2013, unless there are too many raw files in the directory in which I work, OR, apparently, in the surrounding directories (that is, a library of raw files. organized in folders named after the date  In this case, although the program opens very well (even if it can run for a while at the beginning, no doubt scanning the photos in the folder), attempts to change a raw file quickly causes the program to enter a loop of rotation.  The progress on the operation bar to progress issue (change of saturation, noise reduction, etc.) all the way to the right, then the program hangs forever.  In one case, I waited an hour to see if it would eventually take himself off, but no luck.

  If, on the other hand, I do a new folder outside the hierarchy of photo library, copy all the raw (40 - odd of them) files in the new folder, and then the Image Data Converter point to the new folder, it works very well.

  This is a really special bug.  This means that the software works for people who are only noodling autour, but if someone wants to do a serious blow to a large library of publishing, he can forget it!  This is really not the kind of behavior of Sony would allow.

  Hi mr_protocol,

  Thank you for that bring to our attention. We will send this for good service for future updates on the software.

  The code works fine if I remove the 'START' just after the loop and also out of the exception within the loop, but I want to be able to specify what's wrong with each record rather than deal with the correct records and then stop after that it is a record that has, for example, 9 values in a column that accepts only 6.

  Can anyone help with this?

• Convert AAC to MP3 Itunes - 10 Windows files

  ITunes Version 12.5.1

  Windows 10

  I would like to convert AAC to MP3 audio files.  How can it be done?  I would like to transfer my songs on a flash drive to plug into my car audio system to play my songs.  The interesting thing is that on my drive hard it shows that the music file is MPEG-4 audio type - this type of file will play on stereo car if I copy these files directly to a flash drive.

  There was a time when we could select all the songs, right click and select Convert to MP3.

  Thank you, in advance for your answer.

  (NOTE: the songs are already on my drive hard and do not intend to import them again)

  (NOTE 2: If someone used AnyTans - for Windows?) If so, what are your thoughts on his performance?)

  MPEG-4 audio is another description for files to AAC format or .m4a.

  Import or convert the format is defined in Edition > Preferences > General > import settings. You will lose a little quality by converting, so you would normally keep the originals. Define a flow similar to the original. Don't serve him no 128 k AAC 320 k MP3 conversion.

• iMovie imported my clips but did not convert the

  Hi all.

  Recently, I imported a whole bunch of my GoPro clips in iMovie. They seemed imported ok, but when I drag them from the event in the project and then decide I want to make adjustments of speed in clip adjustments, it is said that the clip was not converted - see attached screenshot.

  In addition, displaying some of the clips, some of them do not see smooth, the video will be trolling heavily but audio will continue. This will be resolved once that I convert the clip but it's a bit frustrating when I have to drag the item from the window of the event in the project window and then convert it just to see if I want to use it or not.

  The clips can be converted singularly but takes a while. I was wondering if there was a way to conversion in bulk the clips so that I could just let it run all night and she'll do all clips at once. I have searched through the toolbars, but found nothing. It is mostly just then preview or watch clips or if I want to make adjustments of speed/run the clip towards reverse.

  I made a video in iMovie earlier in the year with images of the GoPro (from the GoPro even) and had no problems with the conversion of import or clip.

  Any help anyone could give me would be much appreciated.

  PS if possible, I don't want to reimport them since I already moved half the clips I want in my project.

  Additional information:

  Computer: MacBook Pro 13 ", about six years, running the Version OS X El Capitan 10.11.4

  version of iMovie: iMovie ' 09, version 8.0.6 (821)

  GoPro used: GoPro Hero4 Silver

  

  I made a video in iMovie earlier in the year with images of the GoPro (from the GoPro even) and had no problems with the conversion of import or clip.

  Were then automatically using El Capitan, or a previous operating system?

  There are many reports on these forums that suggest that worm iMovie 8 and 9 are not compatible with El Capitan.OK on previous operating systems

  Even if you convert the clips there may be other issues.

  The recommendation, if you have problems with the 8 CBS NVA, is to download iMovie ver 10 from the App Store.

  It is not free for users of version 8 it is for users of version 9.

  Version 10 is quite different from 8 and 9 so a bit of a learning curve.

  Do a search here for compatibility with El Capitan iMovie for more information and look for entries of GeeD is the current master

  for iMovie 10 and how to get your events and projects in iMovie 8/9 to iMovie 10.

• T430 heating while in sleep

  Hey guys,.

  I am a new user of Lenovo, come buy my T430 this week.

  After you install all the software that I need on my laptop, I closed (sleeping) and put it in my bag back. I needed only after 2 days. When I hit the bag, it was already hot outside, I opened it and my Lenovo raged... I turned on my computer, the battery is down to 13%, from 100 percent (2 days ago), which is kind of funny that he was asleep, I would have suggested he use about 10 to 15 percent in two days.

  my questions are:

  1. is the heating thing normal while you sleep? What could have caused the problem?

  2 is it possible that certain parts of the computer has been damaged in such a warm atmosphere? (Note that I kept it in a closed bag)

  a possible solution to the question 1: I ran a command prompt, typed in the code that tells me what is allowed out my computer. noticed that the mouse Logitec external and giganet Intel networks have been allowed, so I disabled them both. It was probably the mouse as it was in the same bag, I guess it was moving in the bag and wake up the computer?

  Thank you in advance for your help!

  No, it is not normal. You must set "Timer Wake with battery operation" to "Disabled" in the Bios. It can be found in the Config-> Power, first setting.

  It seems that you escaped without consequences for the moment. Be more careful, turn off the mouse when you're not using it.

• Questions about circuit RC phase difference (possible timing problem)

  Hello

  Here is the program that I use to measure the phase difference in an RC circuit. Simply generate a sine wave of 2 kHz in LabView and send it to the circuit using an analog output. Then I measure the exit sinusoid using an analog output. I also measure using n oscilliscope. I can clearly measure the difference in phase with the oscilliscope and know that it is about 1.4 radians.

  Problems with the program:
  Phase difference different measured each time the program is run for the circuit. It is never as good.

  Possible causes:

  You will notice by looking at the vi that I measure the phase from the signal generator. Can I use a second analog input to measure the sine wave, as it came out at the beginning of the circuit?

  I think it's a timing issue. While the phase difference is constant each time the program varies each track. So the time that each measurement of tone starts its first measure seems to be different every time and causes this reading of different phase.

  The card that I use is a PCI-6221, is there a timing problem associated with switch for input and output audio acquistion or are they separated.

  Is anyway to ensure that two key measures measure phase at the same point in the (real) time?

  I would really advice or changes to the program - could someone offer me (I am a student and LabVIEW is not on our program so I have no support, but I use it for my project (OH!))

  I would certainly acquire two signals.  Food for the analog output right back into an analog input, then your signals filtered in another.

  Initially, I would feed the two analog inputs of the analog output and measure the delay in phase due to the multiplexed A/D on map.  Once you have this measure, you can feed in the filtered signal and then measure the difference of phase of this signal.

• Why my image does not seem normal?

  I just had to reinstall lightroom on my computer and now, something is off when I try to put my images.  When I shoot images in lightroom they look fine in the library, but then I click on to develop and they look like a colorful negative or a histogram instead. I've never had this problem before.  Any ideas how I can get images to look normal while developing their?

  Try turning off the GPU.

  What you do is facing carefully recreate each slide with the items on the sensitive slides.

  See you soon... Rick

• My images are completely different while I work in Bridge and Photoshop (CS6) than they do once they are saved.

  They look normal while I'm working on Bridge or Photoshop but when I saved them (no matter how save them - jpeg, png, it's all the same) and view them with any other program or on any other computer blacks go through the roof and the contrast is too high.  I didn't have this problem at all on CS3 and I use the same computer and the monitor.

  RAW files are on the color profile, you request to Camera Raw for use when they are developed in images.

  

  I don't want to be critical, but now you really need to take it on you to go out and read what you can about color management.  It simply CANNOT be taught both a post on a forum, and you have already seen some of the limitations avoid learning how it works.  It is also quite impossible to guess just with settings and make things - you need to understand what you are doing to be able to make the choice of color management that make sense for you, given your needs and your goals.

  It is not impossible to learn.  How do you think twenty_one and I know how to advise you?  But be aware that there are many people who do not really understand who will try to advise you to "just do it...". "You must understand that what you read will be good and keep at it.  Understanding will rise.

• Your experts & Normal

  Dear all
  
  I have a vo based on some EOs and for certain needs, that I have converted him to read only and not based on an EOs, it will be only to SQL, and so JDeveloper automatically convert the VO of normal in Expert mode.
  
  I put in link vars, stated where clause & sometimes apply VC on this VO of a few grains of back during the execution, after conversion, none of theses will be or I will face any problem?
  
  or I can ask the question in another way * "' conversion in the original Version of Normal Mode Expert, avoiding to use EOs affecting Binding definition, definition where clause or the criteria to view ar DURATION '?" *
  
  Thank you

  It shouldn't be a problem, but it's pretty easy to make a backup of your application and test

• Flash player will not be maximized while that cut

  Running the latest version in chrome, however this happens in firefox and IE so

  When I've maxed a flash on a site like youtube/justintv and dumb video, if I click on another monitor of the flashplayer will return in the browser window instead of stay full screen.

  This does not happen when the sound is not muted, for example I can play a video in full screen on monitor 1 normally while working on Monitor 2, but not while the sound is muted

  Any ideas?

  Thanks for any help
