Could someone explain the select comparison

I am supposed to compare inputs on 2 numeric controls and if they are equal they will turn on an LED. I figured out how to do it with the = sign but I am supposed to use the select comparison. Could someone please help me?
Solved!
Go to Solution.

No, you would not have to have another front panel Boolean to use the Select function. You could directly wire the results of anything that returns a True/False. You can also use block diagram constants.

Could someone explain the Factory Method Design Pattern

Hi Experts.
Could someone please explain for me the Factory Method Design Pattern. I read it a little and I understand that it is used in JDBC drivers but i'm not clear on it.
Could someone explain.
Thanks in advance

Basically, you have one class that's sole purpose is to create instances of a set of other classes.
What will usually happen is you have a set of related classes that inherit from some base class. We'll say for example that you have a base class CAR and it has sub-classes FORD, GM, HONDA (sorry Crylser). Instead of having the user call the constructors for FORD, GM, and HONDA, you can give the user a Factory Class that will give him a copy. We'll call our factory class Dealership. Inside dealership, you can have a static function :
public static Car makeCar(String type)
if(type.equals("FORD")
return new FORD();
else if(type.equals("GM")
return new GM();
else if(type.equals("HONDA")
return new HONDA();
So when the user needs a car, they will just call
Dealership.makeCar("FORD").
This is a good way to hide the implementation of your classes from the user, or if you require complex initialization of your objects.
Another good example of this is in the Swing library. To get a border around a component, you call static methods on BorderFactory.
Hope this helped.

HT4436 I don't see the point of having to create another email account - could someone explain the thinking behind this please?

For iCloud syncing there are a few items that require a new iCoud email address to be created (eg. Notes and email), whilst the majority of other options do not require this.
My question is simply why do these items need yet another email address to be created? I would have though the Apple Id would have been sufficient to hang everything together...
If someone could explain the thinking behind this please I will hopefully be more comfortable with it and probably more likely to start using these features!
Thanks in advance!

If TCP port 25 isn't open, then SMTP services won't work. That's the port that all SMTP servers use to communicate amongst themselves. (Sure, you can change the port your SMTP server is listening on, but you'd also have to change the port processing on all of the other SMTP servers around — and if you did manage to implement that change everywhere, the local network folks would likely just block the new port for the same reasons they blocked the old port.)
If you have a public static IP address and have correct forward and reverse translations — host domain to IP address, and IP address to host domain name — then you don't need and very likely don't want to run your own DNS server.
More to help you learn how these pieces fit together and not something I'd expect you would need given you have a public static IP and public DNS here is a detailed DNS server configuration article for OS X Server; enable Show All Records and it applies to Server.app on 10.7 and later. If you have questions after reading that, I can certainly answer them and also update the article to try to reduce the confusion or answer the question.
Your host didn't have valid reverse DNS, so you'll want to get that cleared up, and you'll want to get the port blocks cleared, or work with the local network folks to set up a relay through one of the existing mail servers.

Could someone explain the following applications?

I am using AppQLaunch and the following applications puzzle me.. None of them open up when I click on them (not standalone exe files?) but they must fill some meaningful purpose I am sure?
-MsgUrlHandler
-NOT
-SMS (brings up System error -2 , why?)
-SysApp
-akncapserver
-aknnfysrv
-essysapp
-lmsrvapp
-psdk_lmsrvapp
If someone could explain those, I would be thankful!

Probably they're all mostly operating system background services or "engines" (or application supplied, if you have installed additional software yourself). Few are documented in any user or developer documentation.
Some of them might be documented in, e.g, Symbian OS internals documentation or books like this one:
http://developer.symbian.com/main/learning/press/books/os_internals/index.jsp
For example, "akn" refers to "Avkon", which is the Nokia S60 user interface/middleware/runtime/application layer on top of the Symbian base operating system.

If you have installed Security Update 2008-002 you need to install the fixed version of it (v1.1) to get the "Printer Settings" functionality back in Aperture.
The adjustment tools in 2.0.1 are the same as the 2.0 version, yes. The new and improved tools are part of the brand new 2.1 release of Aperture.

Could someone explain the differences between the 3 iPod Video versions?

What are the differences between
iPod Video / 5th Generation iPod,
iPod Video 2nd Generation, and
iPod Classic 6th Generation?
If I understand correctly, the only thing that changed between the first two was the size of the hard drives. If that's true, all I'd like to know is what's new in the 6th Generation.

iPod 5.5G has a brighter screen and new search features and 30GB & 80GB models.
classic has better battery life, coverflow, more games, ability to watch rented movies, better battery life and 80GB and 160GB models.

Can someone explain the "colors" channel of the histogram?

I'm using CS4 on a Mac
Could someone explain the "colors" channel of the histogram? Does it simply analyze the image in terms of the % of pixels that are
*blue
*cyan
*green
*yellow
*red
*magenta
*grey

Good day!
It represents which number of pixels have which values in the respective Channel, the refreshed total ("Pixels") is the total number of pixels (image or Selection).

Hi Prabha,
Aggregate Definition :
An aggregate is a materialized, aggregated view of the data in an InfoCube. In an aggregate, the dataset of an InfoCube is saved redundantly and persistently in a consolidated form on the database.
Use
Aggregates allow quick access to InfoCube data during reporting. Similar to database indexes, they serve to improve performance.
An aggregate is made up of the characteristics and navigation attributes that belong to an InfoCube. Characteristics that are not used in the aggregate are compressed.
Each component of an aggregate has to be assigned to a selection type. A selection type indicates the degree of detail to which the data in the underlying InfoCube is aggregated. You can choose one of the following selection types:
All characteristic values ("*"): The data is grouped by all values of the
characteristic or navigation attributes .
Hierarchy level (H): The data is grouped by the hierarchy level node. You can
also store values on the hierarchy levels of an external hierarchy .
Fixed value (F): The data is filtered by a single value .
For each InfoCube, you can set whether the aggregates of the InfoCube are compressed automatically when it is filled with data or after the roll up of data packages (requests).
1. You are in the Data Warehousing Workbench in the Modeling functional
area. In the InfoProvider tree, navigate to the required InfoCube.
2. In the context menu of the InfoCube, choose Manage.
3. In the lower part of the screen, select the Roll Up tab page.
4. Under the Aggregates group header, set the corresponding indicator in
the Compress After Roll Up field.
Standard Aggregation : This means how the key figure is going to be summarized normally for a specific set of characteristics .
Eg : Quantity across all the purchase items for a purchase Order
Exceptional Aggregation : You define how the aggregation should happen basing on a particular characteristic ( Usually time characteristic ) .
Eg : head count ( No of Employees ) in a organisation ..--> this should not be summarized on a daily basis..instead this should give a final value at the end of the month .
Aggregation is basically for keyfigures .
take a look at this doc, you will find all your answer:

Question1: how we will see the based on aggreagate what querys are running
I think "aggreegate maintance screen ---proposal -
query proposal" i am right ,if it is worng pls correct me?
Answer 1:
There are two tools that are used to analyze which aggregate is suitable for which navigation step.
You optimize the start screen of a query with the query Monitor (transaction RSRT) if you execute the function Execute + Debug.
With the trace tool (transaction RSRTRACE) you can draw several navigation steps, and process them again using the function DB Debugging (exact path: Transaction RSRTRACE > Goto > User Logs or All Logs > double-click on the log you want > DB Debugging).
Refer The OSS note 99010
Question 2: When i am creating a aggregate what charteristics we choose i mean based on report/some thing else?
Answer 2:
By refering the Statistical data and comparing the Proposed Aggregates we can create the aggregates.
The above RSRT and RSTRACE will be more useful tools to plan an Aggregate.

Could someone explain why mds is using so much CPU?

Could someone explain what mds is doing if my Mac has been indexed (don't see activity in Spotlight menu bar icon) & I haven't recently added a lot of files?
I noticed my Mac was slowing down for a while so I looked in Activity Monitor & it says mds is running at 60% CPU. Isn't this something to do with Spotlight indexing?

If you recently upgraded the OS or installed an application that includes a metadata parser for spotlight (such software generally comes in the form of a package instead of a single icon), it will force spotlight to reindex. Also, restoring from a backup does the same thing.
Also, if you used mdutil to disable spotlight indexing on the volume and then reenable it, it will force a reindexing.

Could someone explain me about tools like "RICEF"

Hi Guys,
Could someone explain me about tools like "RICEF"(I dont know if iam spelling it correctly) and ASAP methodology. Iam wondering how this are related to SAP upgrade and fresh SAP implementation.
Many thanks in advance.
Warm Regards,
Garrick.

Hi
It would be helpful to go through the help document of ASAP Methodology.
The following information may clarify some doubts/requirements you have.
Generating the Project IMG through ASAP:
After you have set the project scope, the next step is to generate the Project IMG. From the Business Process Master List (BPML), you can directly access the IMG activities relevant for configuring each process.
BPML: The Business Process Master List, along with the Business Blueprint, is a key result of the second phase of the Roadmap. Microsoft Excel tables contain the SAP scenarios, process groups, and processes that have been set in scope in the SAP Reference Structure, and are crucial for configuring your SAP System. In Realization, the third phase of the Roadmap, the BPML provides the basis for monitoring and steering test activities and for configuring your SAP System. It contains the titles of the structure items, and displays the status, the owner, links to documentation and links to the SAP System. Amongst other things, the BPML allows you to:
1) Set your baseline and final scope. These are used for baseline and final configuration.
2) Access the Project IMG and specific IMG activities assigned to structure items.
3) Access integration test plans, which help you carry out all required integration tests.
The Prerequisite is you have set the project scope.
Process Flow to use the Business Blueprint as a basis for configuring your SAP System:
1) Set the project scope.
2) Generate the Project IMG.
3) Generate the BPML.
4) From a specific processes in the BPML, you can go to the relevant IMG activities and make Customizing settings.
Hope this information provides information
