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.

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 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.

Can someone explain the FCE "Levels" Video Filter to me?

Hi,
I need help with the FCE "Levels" Video Filter - I cannot find any documentation anywhere which explains precisely what this filter does and how to use it properly (Googling 'levels "input tolerance" "final cut express"' yields no results!!).
There are five sliders (Input, Input Tolerance, Gamma, Output and Output Tolerance) but playing with them, it's not obvious what they do or how they compare with the Photoshop "Levels" filter for still images.
In particular, I would like to map settings on a Photoshop "Levels" filter to settings on an FCE "Levels" Filter to achieve the exact same results in terms of adjusting the underlying images.
If this can't be done exactly, does anyone know of an FCE Filter which replicates the Photoshop Levels Filter.
Can anyone help? Thanks.

It's not a very useful filter, and is not directly comparable to the Photoshop Levels filter. There is no histogram, which I consider essential.
Input & Input Tolerance lighten the image (they work together)
Gamma adjusts midtones
Output & Output Tolerance darken the image (they work together)
Problem is, you have to drop the sliders off their default settings to get them to work at all. Start by dropping the Input and/or Output sliders to 20. Then adjust the companion Tolerance sliders down to see the effect.
I think you'll have more luck with the Color Corrector filter, which has sliders for Whites, Mids, Blacks & Saturation. Among other things, you will find the numeric levels sliders more comparable to the PS Levels controls.

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.

Could someone explain the cause of the recent print problem (in lay terms)?

I am more curious than anything. It affected me on a R1800. Seems to be back to normal now.
Thanks in advance.

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.

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).

Can someone explain the difference between TIER_WEB and TIER_WEBDEV

Hi All,
We have two sets of values in Context file as below.
<TIER_ADWEB oa_var="s_isAdWeb">NO</TIER_ADWEB>
<TIER_ADFORMS oa_var="s_isAdForms">NO</TIER_ADFORMS>
<TIER_ADFORMSDEV oa_var="s_isAdFormsDev">NO</TIER_ADFORMSDEV>
<TIER_ADWEBDEV oa_var="s_isAdWebDev">NO</TIER_ADWEBDEV>
Could you explain the difference between
TIER_WEB and TIER_WEBDEV
and
TIER_ADFORMS and TIER_ADFORMSDEV

These values in a shared APPL_TOP system. Pl see ML Doc 745580.1 (Apply Patches in a Shared Application Tier File System Environment) for an explanation.Not necessarily in Shared APPL_TOP, even in traditional multi-node installation you will find these values in the application context file.
I never came across any document which describes the difference between TIER_WEBDEV and TIER_WEB, I just can say that these variables always have the same value.

Can someone explain the difference between width, maxWidth, explicitWidth, explicitMaxWidth?

Can someone explain the difference between width, maxWidth, explicitWidth, explicitMaxWidth of the UI component? I read the API and I have no idea what do they mean.

Width is the current width. ExplicitWidth is set if you give an component
an explicit width vs a temporary width via setActualSize.
MaxWidth and minWidth factor in either the measuredMax/MinWidth or one set
explicitly.
