A Chinese saying:
I hear and I forget
I see and I remember
I do and I understand
Try to make sure your study is uninterrupted. You will need to find both the time and place where you can study.
It is important to remember that learning is not a race – everyone learns at their own rate. So don’t rush your leaning – make sure you get the most from the book.

“That's the way a friend described someone she had just met. She was sure (just as I'm sure) that he's going places. Once the determination is in his eyes, the learning will take care of itself.
On the other hand, if I can see the fear in your eyes, then I'm not sure that learning alone will take care of the problem. No one can prove that the path you're on is risk free or guaranteed to work. Searching for more proof is futile. Searching for more determination makes more sense.”

Here's the mistake we make in high school:
We let anyone, just anyone, judge our work (and by extension, judge us.)
Sue, the airheaded but long-legged girl in Spanish class gets the right to judge our appearance.
Bill, the bitter former-poet English teacher gets the power to tell us if we're good at writing.
And on and on.
The cheerleaders are deputized as the Supreme Court of social popularity, and the gym teacher forever has dibs on whether or not we're macho enough to make it in the world. These are patterns we sign up for, and they last forever (or until we tell them to go away).
In high school, some people learn to ship, they learn to do work that matters and most of all, they learn to ignore the critics they can never possibly please. The ability to choose who judges your work--the people who will make it better, use it and reward you--is the key building block in becoming an artist in whatever you do.
“In the infinity of life where I am, all is perfect whole, and complete, and yet life is ever changing. There is no beginning and no end, only a constant cycling and recycling of substance and experiences. Life is never stuck or static or stale for each moment is ever new and fresh. I am one with the very Power that created me, and this Power has given me the power to create my own circumstances. I rejoice in the knowledge that I have the power of my own mind to use in any way I choose. Every moment of life is a new beginning point as we move from the old. This moment is a new point of beginning for me right here and right now. All is well in my world.”

“Your biggest challenge isn’t someone else. It’s the ache in your lungs and the burning in your legs, and the voice inside you that yells ‘CAN’T’. But you don’t listen, you just push harder. And then you hear the voice whisper ‘can’, and you discover that the person you thought you were is no match for the one you really are.”

“You take a born-pretty girl and you dress her up in pretty things, curl her pretty hair and she becomes empty. Vacuous. The only thing she can claim as a self identity is her one dimensional beauty. But take a pretty girl and throw some shit on her, and make her fight her way out of it and she’ll grow to be other-worldly radiant and a force to be reckoned with.”

“Some questions don’t have answers, and that’s a difficult lesson to learn.”

“If ever there is tomorrow when we’re not together, there is something you must always remember. You are braver than you believe, stronger than you seem, and smarter than you think. But the most important thing is, even if we’re apart, I’ll always be with you.”
- A. A. Milne through Julie911
“No matter how big and tough a problem may be, get rid of confusion by taking one little step towards solution. Do something. Then try again. At the worst, so long as you don’t do it the same way twice, you will eventually use up all the wrong ways of doing it and thus the next try will be the right one.”
- George F. Nordenhold through Julie911
In JSF 1, composition components are defined using <ui:composition>. The “template” attribute of ui:composition is optional. Meaning the composition component can opt to confirm to a template or not. So these components could be classified into those that confirmed to a template and those that did not.
Type 1: Composition components that confirm to a template:
A composition component confirms to a template by specifying the template name in the template attribute (e.g: ui:composition template=”section.xtml”). Then it overrides certain aspects of the template. In the example 1 below, section.xhtml, which is the template, defines “contents” (at 1). The composition component defined in Student.xhtml specifies section.xhtml as its template at 2. Section.xhtml further defines-its-own or overrides “contents” at 3. Had there been no 3, 4 would get rendered.
Example 1
Section.xhtml
<ui:composition>
<div…> …
<ui:insert name=”contents”> 1
This is the default text for “contents”. This text will be rendered when a component does not override this ui:insert with a ui:define name=”contents” 4
</ui:insert>
</ui:composition>
Student.xhtml
<ui:composition template=”section.xhtml”> 2
<ui:define name=”contents”> 3
<h:outputText…..> <!—contents of the student section Ã
</ui:define>
</ui:composition>
Type 2: Composition components that *do not* confirm to a template:
A composition component can be stand alone too. In this case the ui:composition tag will reference no template.
outputField.xhtml
<ui:composition >
<h:outputText
Value=”#{fieldLabel}”/>
<h:inputText
Value=”#{field.property}”/>
</ui:composition >
Company.xhtml
<ui:composition …>
<a:outputField
fieldLabel=”Company Name”
field=”#{company}”
property=”name”/>
</ui:”composition>
Migrating to JSF 2:
Type 2 components above are good candidates to become composite components in JSF 2 (as composite components, like type 2 composition components, are stand-alone and confirm to no templates).
| | Composition Components | Composite components |
| 1 | Composition components can use a template e.g. view.xhtml <a:location …/> location.xhtml <ui:composition template=”section.xhtml”> <ui:define name=”contents”> <h:outputText …/> </ui:define> </ui:composition> | Composite components cannot. The need to be decorated to confirm to a template. e.g. view.xhtml <ui:decorate template=”section.xhtml”> <ui:define name=”contents”> <a:location…> </ui:define> </ui:decorate> Location.xhtml <composite:interface> <composite:attribute …/> </composite:interface> <composite:implementation> … </composite:implementation> |
| 2 | Composition components have no constructs to define action listeners and such | Composite components are more closer to a full blown custom component and can hence define action listeners |
| 3 | JSF 1 only | JSF 2 only |
In an application, the UI keeps changing a lot more frequently than the underlying APIs. Designing bearing this in mind would help achieve a better design.
To achieve a effective separation of concerns, the coupling among the separated concerns must be minimal. This way, the implementation of each of the separated concerns have a opportunity to have minimal coupling.
