When we don't see the sun, we see other stars


What are your motivations for creativity?

- I want to make a change.
- It makes me happy! It is a need of my mind.

How to be creative for a thing?

There are two steps:
- See the thing as every people see it
- Think about a new different thing from it

How to think about a new different thing?

There are two ways:
- Forget all things you have already known.
- A whack on the side of your head. ;)

This was what I have learned from the following great book:

Well! A physical whack on the side of your head is needed sometimes but the meaning behind is that you need to break these 9 following locks on your mind. Remove them!

The lock #1: "The correct answer"

We all learn from schools that there is only one correct answer to a question. For example, a proposition is only true or false in Algebra. In reality, there are always some answers to a question basing on a point of view. For example, number 6 becomes number 9 if you look it in the opposite.

The lock #2: "That is not logic"

There are two kinds of thoughts: soft thinking and hard thinking. Soft thinking focuses on finding a relationship among things. On the other hand, hard thinking focuses on the differences between things. The metaphor is a technique of soft thinking which needed for creativity.

The lock #3: "Follow the rules"

Sometimes, creativity is not always a contribution but a damage. However, in order to create a new model, we need to break an old model. Break the rules!

The lock #4: "Be realistic"

Answering the question "if...then what happens?" is useful somehow. For example:

- Imagine if what other people (your inspirational ones) will do in your situation. E.g: I sometimes say to myself when I face an issue: "What will Mr. A do in this situation?"

- Imagine if you are what you think. E.g: Imagine you are a paper; what are your characteristics to make you more convenient for users?

- Imagine an idea which is obviously not realistic. According to this idea, you can come up with a better realistic one. E.g: original idea: the Government will give money for whom put trash into trash bins. Improved idea: every time people put trash into trash bins, they will receive a random fun from the trash bins.

The lock #5: "Play is frivolous"

"If necessity is the mother of invention, then play is its father". There is no doubt about it!

The lock #6: "That is not in my field"

Specialization is necessary in most of the cases; however, bringing a knowledge from a field to another field is really useful as well.

The lock #7: "Don't be silly"

Actually, a comedian is smart. He/she always thinks in different ways. It is like a movement of a car, sometimes it needs to go back in order to go straight.

The lock #8: "Avoid ambiguity"

People avoid ambiguity because it results in the misunderstanding in communication. However, just keep listening to your dreams and playing with it.

The lock #9: "Mistakes are wrong"

In most of the case, a mistake can result in a very bad situation. However, a mistake sometimes helps you come up with some new approaches.

[Snippet] CSS - Child element overlap parent

I searched from somewhere and found that a lot of people says a basic concept for implementing this feature looks like below: HTML code: <div id="parent">  <div id="child">  </div> </div> And, CSS: #parent{   position: relative;   overflow:hidden; } #child{   position: absolute;   top: -1;   right: -1px; } However, I had a lot of grand-parents in my case and the above code didn't work. Therefore, I needed an alternative. I presumed that my app uses Boostrap and AngularJs, maybe some CSS from them affects mine. I didn't know exactly the problem, but I believed when all CSS is loaded into my browser, I could completely handle it. www.tom-collinson.com I tried to create an example to investigated this problem by Fiddle . Accidentally, I just changed: position: parent; to position: static; for one of parents -> the problem is solved. Look at my code: <div class="modal-body dn-placeholder-parent-position&quo

The HelloWorld example of JSF 2.2 with Myfaces

I just did by myself create a very simple app "HelloWorld" of JSF 2.2 with a concrete implementation Myfaces that we can use it later on for our further JSF trying out. I attached the source code link at the end part. Just follow these steps below: 1. Create a Maven project in Eclipse (Kepler) with a simple Java web application archetype "maven-archetype-webapp". Maven should be the best choice for managing the dependencies , so far. JSF is a web framework that is the reason why I chose the mentioned archetype for my example. 2. Import dependencies for JSF implementation - Myfaces (v2.2.10) into file pom.xml . The following code that is easy to find from  http://mvnrepository.com/  with key words "myfaces". <dependency> <groupId>org.apache.myfaces.core</groupId> <artifactId>myfaces-api</artifactId> <version>2.2.10</version> </dependency> <dependency> <groupId>org.apache.myfaces.core<

Strategy Design Pattern

For example, I have a program with an Animal abstract class and two sub-classes Dog and Bird. I want to add new behavior for the class Animal, this is "fly".  Now, I face two approaches to solve this issue: 1. Adding an abstract method "fly" into the class Animal. Then, I force the sub-classes should be implemented this method, something like: public abstract class Animal{ //bla bla public abstract void fly(); } public class Bird extends Animal{ //bla bla public void fly(){ System.out.println("Fly high"); } } public class Dog extends Animal{ //bla bla public void fly(){ System.out.println("Cant fly"); } } 2. Creating an interface with method "fly" inside. The same issue to an abstract class, I force the classes these implement this interface should have a method "fly" inside: public interface Flyable{ public void fly(); } public class Bird implements Flyable{ //bla bla public void fly(){ System.out.pr

Regex - Check a text without special characters but German, French

Special characters such as square brackets ([ ]) can cause an exception " java.util.regex.PatternSyntaxException " or something like this if we don't handle them correctly. I had met this issue. In my case, my customers want our application should allow some characters in German and French even not allow some special characters. The solution is that we limit the allowed characters by showing the validation message on GUI. For an instance, the message looks like the following: "This field can't contain any special characters; only letters, numbers, underscores (_), spaces and single quotes (') are allowed." I used Regular Expression to check it. For entering Germany and French, I actually don't have this type of keyboard, so I referred these sites: * German characters: http://german.typeit.org/ * French characters: http://french.typeit.org/ Here is my code: package vn.nvanhuong.practice; import java.util.regex.Matcher; import java.util

Math fundamentals and Katex

It was really tough for me to understand many articles about data science due to the requirements of understanding mathematics (especially linear algebra). I’ve started to gain some basic knowledges about Math by reading a book first. The great tool Typora and stackedit with supporting Katex syntax simply helps me to display Math-related symbols. Let’s start! The fundamental ideas of mathematics: “doing math” with numbers and functions. Linear algebra: “doing math” with vectors and linear transformations. 1. Solving equations Solving equations means finding the value of the unknown in the equation. To find the solution, we must break the problem down into simpler steps. E.g: x 2 − 4 = 4 5 x 2 − 4 + 4 = 4 5 + 4 x 2 = 4 9 x = 4 9 ∣ x ∣ = 7 x = 7  or  x = − 7 \begin{aligned} x^2 - 4 &= 45\\ x^2 - 4 + 4 &= 45 + 4\\ x^2 &= 49\\ \sqrt{x}&=\sqrt{49}\\ |x| &= 7\\ x=7 &\text{ or } x=-7 \end{aligned} x 2 − 4 x 2 − 4 + 4 x 2 x ​ ∣ x ∣ x = 7 ​ = 4 5 = 4 5 + 4 = 4
