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.

How I did customize "rasa-nlu-trainer" as my own tool

Background I wanted to have a tool for human beings to classify intents and extract entities of texts which were obtained from a raw dataset such as's conversation, Maluuba Frames or here. Then, the output (labeled texts) could be consumed by an NLU tool such as Rasa NLU.

rasa-nlu-trainer was a potential one which I didn't need to build an app from scratch. However, I needed to add more of my own features to fulfill my needs. They were:

1. Loading/displaying raw texts stored by a database such as MongoDB
2. Manually labeling intents and entities for the loaded texts
3. Persisting labeled texts into the database

I firstly did look up what rasa-nlu-trainer's technologies were used in order to see how to implement my mentioned features.
At first glancerasa-nlu-trainer was bootstrapped with Create React App. Create React App is a tool to create a React app with no build configuration, as it said. This tool is also recommended by the official React.js tutorial. I ac…

AngularJS - Build a custom validation directive for using multiple emails in textarea

AngularJS already supports the built-in validation with text input with type email. Something simple likes the following:
<input name="input" ng-model="email.text" required="" type="email" /> <span class="error" ng-show="myForm.input.$"> Not valid email!</span>
However, I used a text area and I wanted to enter some email addresses that's saparated by a comma (,). I had a short research and it looked like AngualarJS has not supported this functionality so far. Therefore, I needed to build a custom directive that I could add my own validation functions. My validation was done only on client side, so I used the $validators object.

Note that, there is the $asyncValidators object which handles asynchronous validation, such as making an $http request to the backend.

This is just my implementation on my project. In order to understand that, I supposed you already had experiences with Angular…

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 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</groupId&g…

My must-have apps for daily work

There is no doubt that cool apps can help us be more productive and enjoyable at work. For the time being, I really love the following apps which are used by me almost every day.
1. A personal Kanban In fact, a personal kanban is the most useful app for me. Why does it matter? It is not just a to-do list, but it keeps me motivated every day because it helps me be able to know what my "big picture" is. I usually set up my plans together with a path to reach them. KanbanFlow is my preferred tool.
2. A terminal Needless to say, a terminal is a must-have app for every developer, especially the ones use macOS/Linux. Due to its importance, I love to decorate and enhance it to be super exciting with various tools such as iTermoh-my-zsh, and thefuck. ;)

3. A documentation "ecosystem" As a developer, I can not remember all things that I have experimented a day. Moreover, a document is really useful for sharing an idea with other people. I use the set of tools for helping…

Strategy Design Pattern

For example, I have an program with an Animal abstract class and two sub-classes Dog and Bird. I want to add a new behavior for the class Animal, this is "fly".  Now, I face to 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 interfaces with method "fly" inside. The same issue to 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.println…
