  Why use of UTP Cable more than twisted pair cable twisted pair cable STP?

  Hi stuckfree,

  UTP (Unshielded Twisted Pair) cables are the most commonly used cables for ethernet connections and have a number of advantages. They rely on the effect of cancellation caused by the twisting of the pairs of wires to handle noise, which is uses more than enough for most domestic. They are also smaller than STP (shielded twisted pair) cables, which makes them easier to install, especially in bulk or in narrow spaces. They are easier to install than the sewage and do not require the presence of a ground cable. UTP cables are also cheaper than the STP cables and do not require as much maintenance, since they do not rely on an external display, and can transmit data as fast as the STP cables.

• Why the LR5 catalog is better than PES 12 organizing?

  Jim

  I started using a trial version of the LR5.

  I've been a regular user of the different versions of the EP over the years.

  In general, I was pleased by the Organizer, & have various tags nested in each other.

  I've never had a problem with it being unstable, and can usually find what I'm looking for.

  (provided that I have correctly tagged it in the first place :-))

  My first impression of the LR5 catalog is that it is not as intuitive.

  I searched online for how to install the catalog & most of the discussion relates to catalogues how to have. -J' have already made that decision - just one:

  So?  What are the features I am missing in the LR5 catalog that make it better than the elements Organizer?

  What do you think?

  I am also a happy user of the Organizer, but I also use LR 4.4.

  What I find interesting in LR:

  -huge amount of customization possible and options (if you need it...)

  -Ability to handle JPEG files as well as the raws (the Organizer doesn't let you open JPEGs in acr,)

  -Smart ways to manage variants without copying files (virtual copies)

  -The most advanced metadata management

  -possibility to merge catalogs

  -Much more supported by Adobe and user forums

  -Advanced options in the output in the latest versions

  What can be the subject of a debate, it's the difficulty of the learning curve, as well as the "robustness" of the software. The organizer has riddled many bugs (there were already several years before LR). The problem is that after having much more options makes more complex LR. For example, the database has three times the number of tables. It follows that LR forums are full of complaints about bugs or missing features... just because it's too rich and trying to satisfy the needs of each.

  Several cases of problems with the Organizer are related to the function of backup that backs up the images and catalogs. Catalogues only backup LR. Backup of images is your responsibility. If you have problems, it isn't for lack of LR, it's yours.

  I can't find a post I made to show the possible benefits of the Organizer, but it was just for fun.

• Why is windows 7 better than professional?

  I was wondering why is windows 7 better than professional, because I want to see what features ultimate has this professional is not

  Ultimate has some extra multimedia features, such as Windows Media Center.  It also has the ability to run multiple languages, I think. In addition, there is not much difference.  And if you do not need to connect to a domain, home edition Premium you will probably give everything that you need and want (and more).

• When shooting images for 'HDR Pro' sources, is it better to use TIFF 16 bits rather than 8-bit JPEG?

  When shooting images for 'HDR Pro' sources, is it better to use TIFF 16 bits rather than 8-bit JPEG?

  When shooting for HDR, it is preferable to the Raw format.

  When you import the image to gather in HDR and you use JPEGs, Photoshop will show you the message that it is better to use the Raw instead of JPEG...

• Why use the collections?

  Please help me to better understand and to right the next point
  
  to move from a PPT available in internet, I read a sentence under the heading "Why use collections?" Please find here
  
  Use of complex data sets information to host non-PL/SQL environments using table functions
  
  I think I understand: it means that complex data sets can be collected from oracle using only a single sql statement by using the installation, called Oracle Pipelined Table functions. http://www.akadia.com/services/ora_pipe_functions.html]
  
  Is any other installation in oracle to the serveup of complex datasets of the information to the host non-PL/SQL environments?
  
  Published by: o Manjusha Muraleedas, error corrected spelling.

  I watched the presentation and here's how I read it (although you might be better to ask the author):

  Manjusha Muraleedas wrote:
  My question is, why the statement "Serve up complex data sets of information to host non-PL/SQL environments using table functions" came under the title "Why use collections?". Just because there's an installation? or any other really good news?

  There is a hypothesis that is unwritten in the presentation: "complex" data is data that must be handled in PL/SQL, because only SQL does not work.

  Nowhere the author says that a pure SQL solution should be changed into a solution of PL/SQL.

  Once you decide that you must use the PL/SQL, you might want to put your data in collections in scalar variables.

  I understand, complex data, works of art (suppose a structure with 3 columns of tables joing 5) can be meet non-pl/sql envirormment like Java, the use of the ref Cursor or xml. Collection using to do the same thing, this is not a good option.

  Again, I think that the author uses "complex" as a shortcut for 'need to PL/SQL in the first place'. If the data must be processed in PL/SQL, there is no need to use PL/SQL scalar variables or collections.
  I would say "use of the ref Cursor. Providing relational data in format XML should be the exception, not the rule. It has a cost of additional performance.

  Now lets talk about pipeline table functions.
  ...
  functions table pipeline reached the performance of parallel processing. so even if binding commodity of time and memory is there, it will be performs better than refcursors or xml?

  Pipeline table functions perform no better than the ref Cursor. There are two processes running, one to SELECT and the other for the function, there will be more work on the server. With a ref cursor, there is a fair process to return the data.

  Parallel processing is not a problem. If you can make it work in plain SQL, you can do in parallel in SQL simple.

• Why use Top Link is the best in the DB adapter?

  Hi all
  The one you suggest, why use Top Link (Build-in Insert, operation Select etc.) is the best in the DB adapter using the custom query above?
  
  Thank you

  Hi Michel,.

  to insert / select, it depends on what kind of user you are. TopLink allows you to browse and click on tables and have everything generated for you. If you're a DBA or show me the SQL type then you can simply type SQL directly.

  Some benefits of TopLink would be:

  -The range of SQL generated by TopLink is limited, but if you hard code SQL complex in your service you need to keep it.

  TopLink - can generate when executing the correct SQL for a database, to tell DB2 to Oracle easy.

  -L' merge operation will compare the XML of the columns on the data entry and update only what has changed. It can also make a sparse merger. If only have been 4 columns in the XML file, only 4 columns in the database will be updated.

  -For the incoming interrogation strategy (LogicalDelete, table of sequencing, etc.) is a configuration property and then at run time, several SQL statements are generated. Also leverages the SQL syntax advanced like the Oracle only for UPDATE SKIP LOCKED, he wrote everything yourself can be tedious and error-prone.

  -The main advantage of TopLink is when you go beyond the thinking on one table. If you import more than one table at the same time, TopLink will generate SQL code to select maintain several tables, set the validation and generate a hierarchical XSD. With custom SQL the corresponding XSD is always flat. That is, if you just need to insert a PGE that you could get away with custom SQL. If you need to insert a dept and EMP, I'd use TopLink.

  -C' when the intermediate abstraction of an object/array is also more logical, because you only need to import a schema relationship complex once, then generate inserts, selects, etc.

  So I hope this helps. They are each just as viable and can do something that the other cannot. Where you see an overlap I would go with your personal preference.

  Thank you

• 'there is no' better than 'in '?

  Hi all
  
  I have a doubt. I read on some forums oracle and bands use "does not exist" clause is better than use "in". Is this true? Why? My case is as follows. On my where clause, I need a subselect.
  
  ...
  AND do NOT EXIST (SELECT a table where b = c.roomcode)
  ...
  
  One of the reasons that I can read (but I want to know your opinion) uses "does not exist", when select it search for the first row, stop select it and the result of this operation is false. Is this true? Stop with the first row? Or do the all request and assess after the operator "does not exist"?
  
  Kind regards
  Jordi,

  In general make sure that when you do NOT use the operator you want to scan an important part of the Table. Because the CBO goes hand in hand with the assumption that you use each time or NOT <> operator you will take a large part of the table and it goes for FULL TABLE SCAN.

  Even when you force for an index with a hint he's only going to INDEX FAST FULL SCAN. A range scan is never an option by the NOT operator.

• Why use partitioning and key-associator key features?

  Why use partitioning and key-associator key features?
  
  What kind of application are not suitable for the use of the features key-associator and partitioning key?
  Could you give me some examples?
  
  Thank you

  So the typical is to use KeyAssociation. It is a unique interface which uses a method

  public Object getAssociatedKey();

  I think that it works on the ClusterService level (rather than saying the Cache). For example, if you have a customer and a cache of account where a customer can have multiple accounts. Now, the customer and the account object will implement KeyAssociation and return the customer object as the AssociatedKey. This will cause these items to live on the same partition.

  Now you can do some clever tricks since you know that they are on the same partition. These include the use of the BackingMap and EntryProcessors / InvocationService / aggregators to return all AccountIds associated with a customer account (essentially a join).

  Unfortunately, these are enough consistency of the advanced so it is better to build first of all in a unit test and get them working before you include in your application.

  Best, Andrew.

  PS. You can also use the KeyPartitioningStrategy, but I prefer the KeyAssociation (like most people).

• The Vista is better than Windows XP Home edition?

  Hello

  I installed vista, but is not supported & is unlikely to be the main programs I want to use with it! Is it because Vista is new, or Windows XP Home edition (which he runs under) is a better OS.

  I read on the forum that WXP can be used in another partition. This would cause a problem? How would be affected other things like access to internet or e-mail if I used it in a partition?

  Need help please, I'm lost and want to know the best thing to do.

  Thank you.

  Hello

  Vista should be better than XP, but now many 3rd-party devices and programs are not compatible with Vista and therefore it s advisable to use two BONES; XP and Vista.
  You can install the two OS s separately on two partitions.
  This should work.

  With regard to the reception of the email: Please check where the e-mails are stored.
  Especially as Outlook e-mail applications use a same folder of installation on the partition for saving e-mail. But the path can be changed in the settings somewhere.

  A few words about Vista. As you probably n t know the needs of Vista a lot more material resources such as other early BONE. You will need a really fast and high performance for laptop or desktop PC to use all the features of Vista. I'm talking about the Aero glass effects, etc.

• Is Digital Zoom precision on the Nex 5N and al better than simply cropping in post-production?

  The main question in the subject line. If the answer is 'no', what is the new clear Image Zoom. It provides nothing that I can't do post-production with cropping?

  If previous digital zoom and turn off zoom of the image are not better than cropping, software like The Gimp would be sufficient, or would I need pro-level photo editing software?

  Thanks in advance!

  Hi lporrel,

  As the camera will only m the image zoomed in and you might get a correct exposure for this small part of the image, this is a good option to use the digital zoom.

  When you use the digital precision, Zoom auto focus feature works with priority on and around the central region.

  While in the cropping a picture, its quality will remain identical to the original image, but the size will be smaller.

  If my post answered your question, please mark it as an "accepted Solution".

• iMovie dealt with only 4 k better than the first. I got lost? Help

  I'm trying to see if I'm doing something wrong or missing something. I have 4 k 3840 x 2160 footage recorded on my iPhone that I have downloaded on my i7 3.5 ghz quad core, nvidia 1070, 6 GB ram, ssd, pc on Adobe and without using a proxy, I could not change the images. The raw 4 k has been trolling and freezing and would not play even at 1/8 res. OK for fun, I imported the images into iMovie (not CPF) on my old 2012 4 GB of ram, i5 2.5 ghz MacBook and it instantly imported and washing and playback was flawless. I'm lost. How is it. I didn't choose any encoding in iMovie. Is there some choices I select first or something. Also I know that it's the Adobe forum and I write for someone who is familiar with both platforms that I am trying to get my PC and first to work like the move

  I don't know anything about it on Imovie... another that he is not a pro NLE. And some of the video apps fans are specially designed to work with the VFR, that most of the pro NLE are not.

  Many 'film amateur' apps take a lot less computing power to work, as... Well... they are far away as complex and big a program. Don't want not to say that they are not very good for what they are designed to do, only that they have a different fill niche.

  The standard to get images of the iPhone in PrPro, recommendation is to use the free program of handbrake to convert the VFR in CFR iPhone and then import them into PrPro.

  Handbrake download page: https://handbrake.fr/downloads.php

  And no, I would not recommend trying to import VFR and PrPro do proxies on ingestion... convert to the CFR before import, or use other applications to change.

  IMovie can work with this phone better than PrPro images, but... There's a hell of a lot of things PrPro can do that Imovie can not even dream of. If you need those, then your application PrPro. If not, well...

• Lightroom is really better than a bridge and ACR?

  I use Bridge and ACR for years. I have been turned off to learning Lightroom, but feel I can do is not so much because it seems the standard for photo editing.

  So I sat down and tried to understand, and it was a pain in my butt. I guess that's just the learning curve, but it is not as simple as I thought it would be.

  Is it really that much better than ACR and bridge? Should I even waste my time to learn?

  If you have a good Bridge/ACR workflow then technically has no interest that Lightroom if you compare editing capabilities. Lightroom and Camera Raw have both share the same raw processing engine. You can get the same results of both programs. I switched to Lightroom years because I just love some of the things in the interface is better I like to work with Camera Raw. But it's my choice. I take no sides of the cataloging features as much as I can in Lightroom. I use it mainly for the develop module features. And I want to print from Lightroom as well. I don't think you should feel loose or lower when you talk to other photographers, just because you use Camera Raw and Bridge. Tools can give identical results. It's mostly a matter of choosing which is best for you.

• Which Adobe product is better than the sliders &amp; banners (graphic design) for a Web site?

  Which Adobe product is better than the sliders & banners (graphic design) for a Web site?

  You can see the full list of applications here:

  Common questions about CC desktop applications

  Desktop applications

  I'd take a peek at Photoshop or Illustrator.

  Photoshop is a pixel based image editing program that is well suited for creating and editing digital images, especially photographs.

  Illustrator is a vector program that is great if you want to create vector graphics based that you can scale up without loss of resolution, for example, a logo.

  What you choose really depends on your needs and knowledge if you create bitmap images or vector.

• Error when the concatenation of CLOB using conversion implicit to_char

  Hello
  
  Please look at the code below (Oracle 11.1.0.7.0):
  

  DECLARE
    c CLOB;
  BEGIN
    FOR i IN 1..10
    LOOP
      -- Please uncomment ONE of the lines below
      c := c ||  LPAD('x', 8000, 'z') || i; -- raises error ora-06502
      --c := c || (LPAD('x', 8000, 'z') || i);  -- works
      --c := c ||  LPAD('x', 8000, 'z') || to_char(i);  -- works
    END LOOP;
  END;

  OK, making use of implicit type conversion may not be the best thing to do, but just out of curiosity, is there any explanation for this error to occur?
  
  It seems that, when an implicit conversion is involved without the help of hooks, Oracle tries to convert all in varchar2 before concatenate in the clob, which causes the error.
  
  Thank you
  Luis

  Hello
  >
  # 6.1, we have a clob and a varchar2, as in #2; Why Oracle has decided to convert the clob in varchar2 as you say, and not vice versa as in #3?
  >

  # 5, we have clob and number at the beginning. In order to evaluate the expression oracle requires that two variables was of the same type.
  As the implicit conversion there is no number-> clob
  but there are several-> varchar2 and clob-> varchar2 oracle choose this one.
