  HI comrades LabVIEW in love.

  Could someone let me know why the 2 screws attached do not run at the same speed I expect?

  Inside the event, value is only designed for the value of signalling events on the time-out, i.e. every 100 ms.

  Outside of the event is happening at the same time, so he writes to each iteration of the loop, and the timeout never occurs.

• Why the proxy settings are not respected

  I set up SSH as a proxy server on my laptop when I'm on a public network and configure Firefox to use the proxy by completing the manual Proxy config.

  If SSH doesn't work, I get this error message as expected: "the proxy server refuses connections" when I try to access any website EXCEPT Google.

  Searches on Google and access Google.com still works, even when the proxy server is not up. That seems broken.

  When the proxy server IS up, Google searches do not appear to use it.

  Google is my default search provider. If I try to access Bing, Firefox is behaving as expected (no access when proxy is out, throw up debugging indicating new connections when the proxy is up). If I change from Bing to be default search provider, the behavior of the two remains the same (proxy will use Bing, Google does not work).

  Why access to Google (and only Google?) ignore the proxy settings? Are there other sites of 'magic' that would also ignore the proxy? I use the proxy because I want to protect my internet traffic when I'm on public networks, if Firefox can randomly ignore them for some sites but not others, how can I trust him?

  My configuration problem. I realized that any site that uses https worked, while others are not.

  Somehow the "use this proxy server for all protocols" got unchecked. Audit, it solves the problem.

• Why this CASE statement would not work?

  If I use a CASE in my SELECT statement and met a strange thing and just need help to understand why he did it.
  
  When I type this, it does not work:
  
  CASE TRIM (Column1)
  WHEN NULL THEN Column2
  WHEN 'foo' THEN Column2
  Of ANOTHER Column1
  END AS NewColName
  
  I use this query in an Oracle procedure to insert data into another table. The data inserted in the column of NewColName end up being 4 empty spaces, located in Column1. In the logic of this, TRIM must remove all the empty spaces, and he should get mapped to the first statement WHEN, who must insert the value of Column2, but that does not occur. I tried the following versions of the first line as well:
  
  LTRIM (RTRIM (Column1)) CASE
  CASE of REPLACE (Column1, ' ', ")
  
  and they all produce the same result. I also tried to change WHEN NULL for WHEN " and it changed nothing. However, when I rewrite the statement in this way it works the way it should:
  
  CASE
  WHEN TRIM (Column1) IS NULL, Column2
  WHEN TRIM (Column1) = 'foo' THEN Column2
  Of ANOTHER Column1
  END AS NewColName
  
  In my mind, it seems that these two methods are trying the same thing, why we could work and the other not? Only, it has no sense to me.
  
  Thank you

  Hello

  Welcome to the forum.

  In your first statement, you have

  WHEN NULL THEN.

  This is the same as x = NULL.

  Nothing is never equal to NULL, if you find yourself in your ELSE clause.

• Help - why the songs that are not on my iPhone appearing in my list of app music albums/songs?

  I have over 500 GB of music on my Mac, so I create a playlist for the songs I want to sync my iPhone. Yet when I look at my phone, there are many songs that are not in sync would be playlist. They cannot be read unless the phone is connected to my wifi at home, but I don't want them cluttering up my phone and makes it almost impossible to find the tracks I want to listen to.

  I hate the new music app. For the first time since I converted to Apple 10 years ago, I wonder if I can be forced away because it's so horrible. Why ruin a great product with terrible software? Anyway, if anyone can help me to fix this serious bug, I would be very grateful.

  If you go to the library of the screen and press the red text just below the icons of the album/playlist (where you select whether you want the screen to show the view of the artist/Album/songs downstairs there is a toggle to only show that downloaded music.) If you enable this, then only the songs that are actually ON your iPhone will be in BLACK characters. The rest of your music library to iCloud either won't display at all or be grey. Now - if you have a few streaming, you can see more songs, because the songs that are heard are cached in the memory of the iPhone box and supposedly deleted automatically when it fills up (but not user accessible unless you use some third-party programs).

  What you can do - so they need WiFi or data cell-, it's make a playlist in iTunes that you want on your iPhone. Then (assuming that Apple music and iCloud music library are running on both), you can go to the playlist and press the small cloud/down arrow icon and download these tracks on your iPhone. Then, you can play these songs without access to wifi or cell phone.

• Why this SQL statement is not recovering this indicator of index?

  SYSTEM_REFERENCE1/2/3 are VARCHAR2 columns.

  Oracle is to resolve the query by using an implicit "TO_NUMBER" on each column, which makes the path of the index not available, you can check it out using SET AUTOTRACE ON and observing:

  Predicate Information (identified by operation id):
  ---------------------------------------------------
  
     1 - filter(TO_NUMBER("SYSTEM_REFERENCE2")=407530 AND
                TO_NUMBER("SYSTEM_REFERENCE1")=669014 AND TO_NUMBER("SYSTEM_REFERENCE3")=1)
  

  If you explicitly put quotes or "TO_CHAR" around the values then the index will be used. For example:

  select
  /*+ INDEX(pa_cost_distribution_lines_all pa_cost_distribution_lines_n5) */
  system_reference2, system_reference3 , system_reference1,
   EXPENDITURE_ITEM_ID
  from pa_cost_distribution_lines_all
  where
  --eXPENDITURE_ITEM_ID = 734145
   system_reference2='407530'
  and  system_reference3 = '1'
  and  system_reference1 = '669014'
  /
  
  Predicate Information (identified by operation id):
  ---------------------------------------------------
  
     2 - access("SYSTEM_REFERENCE2"='407530' AND "SYSTEM_REFERENCE3"='1' AND
                "SYSTEM_REFERENCE1"='669014')
  

• Why the acquired data are not from min to max (DAQmxCreateAIVoltageChan, PXI-4472) values

  Hello

  I'm developing a program for the PXI-4472 acquisition on opensuse 11.4 device (linux 2.6.34).

  I try to acquire analog data and to read in a wav file.

  Configure the task of acquisition with the following functions:

  DAQmxCreateAIVoltageChan(taskHandle,"Dev1/ai0","OnboardClock",DAQmx_Val_Cfg_Default,-10.0f,10.0f,DAQmx_Val_Volts,NULL);
  DAQmxCfgSampClkTiming(taskHandle,"",48000,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,48000);

  DAQmxDisableStartTrig (taskHandle);

  I don't understand why the data stored in the wav file are not-10V,-10V but-5V, 5V... (the value of the gain is 0dB). (Perhaps a scale of 0.5?...)

  Thanks for your help,

  Amandine

  You're right, in my example, I considered as unsigned data.
