• I do not understand this statement "It is a good idea to keep track that uses a bunch of Audio channels selected in the arrange window, unless you actively play or record on a software Instrument."

  It's a good idea to keep track that uses a bunch of Audio channels selected in the arrange window, unless you actively play or record on a software Instrument.

  Which no longer applies in Logic Pro X 10.2.3. In old versions of logic, selecting a range with a software instrument automatically would make this instrument in "Live" mode, which means that the instrument has begun to transform any MIDI in sound with a minimum of delay. This direct mode becomes an instrument need CPU power (on a single processor) and peut overload the audio engine. It is a waste of CPU if there is no direct game. Then select an audio track would ensure that No instrument is in direct mode. Now (LPX 10.2.2 or more) in direct mode can be turned on or off on a track, chosen or not - it is the R button on the track header.

• I do not understand this code

  that means "window.parent.document.forms".

  is there a way to know what mean without having the rest of the code?

  	Alert ('Aviso!');
  	Window.parent.document.Forms [0].edAlgo.Select ();
  	Window.parent.document.Forms [0].edAlgo.Focus ();

  It is a JavaScript question, not a question of ColdFusion, but I'll try to answer anyway.

  window = self.

  parent = self is a child window's parent window that gave birth to oneself.

  document = document object (the code) model.

  Forms [0] = first shape in an array of forms.

  Window.parent.document.Forms [0] = (parent) window form opening.

  . adAlgo.select () = form element select 'adAlgo '.

  . adAlgo.focus () = place cursor on the form (focus) element "adAlgo".

  It seems that it is a part of the validation of the form; If something in adAlgo is not correct, place the cursor there so that the user knows that the value must be corrected.

  It's a full proposal, of course.

• Toshiba 39L4333DG CloudTV: I do not understand! Guide needed

  Hello

  I've just set up my new TV, I think it's great (besides being too slow), but I do not understand how to use the CloudTV.

  My TV came with NO manuals: it included only a quick installation guide and a brief description of cloud TV.
  I was able to download the full manual, but it says to look at the TV guide of cloud that I can't find anywhere.

  So I have set up my user in the TV of cloud, but how can I manage my messages? Or who are the 4 guys right suggesting me things to see, based on what?

  If anyone can provide Cloud TV guide PDF or some other form of guide?

  Thank you very much!!!

• I do not understand file history

  What is that thing in the history of the files all about?  All the explanations I've found are so shallow and does not explain what he actually did.  What are all of the advanced options and how they do it?  Why can not I just have a complete and detailed description of how to use it?

  I put it up to send files on a network drive.  There are about 100 GB of photos, music and documents in my libraries.  He sat there for two days, saying: it was market back them and whenever I checked to what extent she had progress was pathetic.  What is it meant to be so slow?  Why can't have just a progress indicator to show what he does?

  Historical files seems to take 80 GB to save backups to about 40 GB of files, even if I did not bring any changes or the file structure, and this is the case when it is only about to half way through all my backup files.  It must make a complete backup of base before trying to do things smart version?

  I don't want you to save hundreds of versions of files, my destination drive is not large enough for this.  I want to save a version and leave it at that.  I have a 200 GB backup drive and 100 GB of data to go inside.

  Microsoft is trying to make it intuitive and simple, by simply not explain it in detail.  But when he doesn't have what you want and you do not understand this policy is of no use.

  Can anyone point a complete and detailed guide decent?  Maybe someone can help answer some of my ignorant questions above?

  Thank you

  Historical files would probably meet your needs.  It is not a copy of a versioned file if this file has not changed, so it would indeed give you one copy of this file.  Of course if you have modified the source file, it would keep the two if you can "go back".

  If you don't want that kind of thing of time machine, you can actually do what you want with a programmed control.  Some people use the robocopy command, but I'm not too familiar with it, and I prefer the simpler xcopy command.  For example, this command copies all the files in the Documents folder on the hard disk in E:, overwrite files already on E: (so replace it with the latest version).  The other options I used are described in the screenshot below:

  xcopy C:\Users\Shawn\Documents /s /v/c/i/q/y/z per day

  You can put this in Task Scheduler and tell him to repeat every night at 04:00 or something your backup is never more than one day old.

• I want to use a Terminal Airport Express to extend network provided by my Fios router/modem without going through another airport base.  Is there a way to do this?  I understand that Apple does not support this, but surely there must be a way to do this.

  Can someone tell me how to set up an Airport Express Terminal to expand Network provided by my Fios router/modem without going through an airport as a base?  I understand that apple does not support this use, but my applecare Advisor said it's possible.  Thank you!

  Unfortunately, your AppleCare Advisor is wrong if he or she has told you that an AirPort Express to extend wireless signal of a Fios router/modem.

  Function of "Extend a wireless network" Apple is an exclusive feature that was designed by Apple engineers to extend the signal from another wireless only router from Apple. Thus, the AirPort Express... or any other router Apple besides... would not be able to extend wireless a Fios network.

  SO... you have the possibility to locate the Airport Express where it is needed... And... Connect it to the Fios router/modem with a permanent, wired Ethernet cable connection, then the AirPort Express can 'extend' in this way.

  Or... If you are ready to add a second AirPort Express, connect the first near Fios modem/router with an Ethernet cable, then the second Airport Express could extend the signal first Express wireless.

  Another way to say the same thing, is that if you want an Apple AirPort router to extend wireless network... then you need two Apple routers to achieve this goal.

• Query Sub behavior strange when using Expressions regular Oracle

  I met a strange "inconsistent" when you use an Expression regular Oracle with subqueries in SQL. Here are some details on how to reproduce what I have observed. We managed to find a solution to this "problem" using a database index; I'm writing this case hoping to better understand why Regular Expressions Oracle do not seem to work in the same way that the older, standard functions integrated as INSTR, SUBSTR, AS, etc..
  
  Environment settings:
  This test has been done using Oracle XE (GR 11, 2) on 32-bit Windows operating system. For my test, I used the HR schema (which is delivered pre-completed with the installation of this product) with some modifications of my own.
  
  Make the Test objects:
  

  create table hr.emp_test as
  select to_char(employee_id) as emp_id_char, employee_id as emp_id,
  first_name, last_name, hire_date
  from hr.employees;

  To illustrate my test, I inserted mixed alphanumeric values and a null value in the column of my emp_id_char for good measure:
  

  insert into hr.emp_test (emp_id_char, first_name, last_name, hire_date)
  values ('XKCD123','TEST','LASTNAME',sysdate);
  insert into hr.emp_test (emp_id_char, first_name, last_name, hire_date)
  values (null,'TEST1','LASTNAME2',sysdate);
  commit;

  * (1) this request fails once a nonnumeric value is inserted into the emp_test table.*
  

  with
     sub1 as ( select to_number(emp_id_char) as emp_id, first_name, last_name, hire_date 
        from hr.emp_test  )
  select * from sub1
  where emp_id between 100 and 110

  * (2) this query works OK.*
  

  with
     sub1 as ( select to_number(emp_id_char) as emp_id, first_name, last_name, hire_date 
        from hr.emp_test where emp_id_char not like 'X%'  )
  select * from sub1
  where emp_id between 100 and 110

  * (3) this query works OK.*
  

  with
     sub1 as ( select to_number(emp_id_char) as emp_id, first_name, last_name, hire_date 
        from hr.emp_test where instr(emp_id_char,'X',1) = 0 )
  select * from sub1
  where emp_id between 100 and 110

  * (4) this query Fails.*
  

  with
     sub1 as ( select emp_id_char, first_name, last_name, hire_date
                 from hr.emp_test

                from sub1 )

  from sub2
  where emp_id between 100 and 110
  
  ERROR:
  ORA-01722: invalid number

  * (5) even down the results of the rational expression of 3rd under the query in sequential processing order also FAILS *.
  

  with
     sub1 as ( select emp_id_char, first_name, last_name, hire_date
                 from hr.emp_test
                where regexp_instr(emp_id_char, '[^[:digit:]]') = 0 ),
     sub2 as ( select to_number(emp_id_char) as emp_id, first_name, last_name, hire_date
                from sub1 ),
     sub3 as ( select emp_id, first_name, last_name, hire_date from sub2 )
  select *
  from sub3
  where emp_id between 100 and 110
  
  ERROR:
  ORA-01722: invalid number

  * (6) that it does not like previous query as well *.
  

  with
     sub1 as ( select to_number(emp_id_char) as emp_id, first_name, last_name, hire_date,
         regexp_instr(emp_id_char, '[^[:digit:]]') as reg_x 
         from hr.emp_test 
         where reg_x = 0),
     sub2 as ( select emp_id, first_name, last_name, hire_date, reg_x
        from sub1 where reg_x = 0 )
  select * from sub2
  where emp_id between 100 and 110
  
  ERROR:
  ORA-00904: "REG_X": invalid identifier

  Our Solution...
  Add a hint to the query of sup that 'hiding' the result of sub1 in memory. That did the trick. This suspicion resembles only viable workaround for this behavior. Other old built-in functions (INSTR, AS, etc.) an they were automatically following the execution plan (results of cache memory) that he had to use a 'hint' to force with the function of the regular expression.
  
  The conclusion, which is what I would like to help to understand or explain is that:
  If you create a series of queries/sup queries or inline views, values depend on "regular expression" type built-in sql functions do not seem to stick or maintain when implemented in complex query logic.
  
  Any idea is appreciated!
  Thank you!

  This is the expected behavior and has nothing to do with regular expressions - much less directly (I'll explain later). Main rule: there is no WHERE clause predicate order. Even if you use views, views online, subquery factoring, optimizer etc. can extend your display, display online, a subquery factoring. And it's Optimizer who decides the order of execution predicate unless you use the ORDERED_PREDICATES key. Now, I can explain. Regular expressions are powerful enough but also everywhere in life to pay for it with the higher cost of execution. That's why optimizer decides to apply emp_id between 100 and 110 first and regexp_instr (emp_id_char, "[^ [: digit:]]'") = 0 later.

  The bottom LINE: With the help of strings to store non-chaine (numeric in your case) is never a good idea and shows design problems.
