Trước Bình Minh Luôn Là Đêm Tối

This is a book telling about many stories of the book's author, Ta Minh Tuan. Each his story is not only a valuable lesson but also a heart-to-heart talk.

Think Big, Start Small, Move Fast

I accidentally attended a $2 meetup which was held by in 2013. It was the first time for me to see the author. At that time, he wanted the attendees to repeat many times a sentence "Think big, start small, move fast" (a mindset for entrepreneurs). It was really impressed to me. I've been following him on Facebook since 2013. This book was his recommendation.

Do It Anyway

Your success is defined by yourself. It is built by your habits. Habits are the things need time to tackle. To me, that somehow means JUST following your heart combining with your brain because you're the one who knows what you're doing. Believe in yourself and never betray your dream!

We Are One

The author said that "everything is connected". This is also the theory of Buddha. He believes the existence of Atlantis and its elimination is a lesson-learnt. In order to avoid the elimination of our world, we have to help rather than harm the others. His company called "YUP" (its pronunciation also means "help") is a school for training entrepreneurs which follows the philosophy: "bring values for the community".

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…

Only allow input number value with autoNumeric.js

autoNumeric is a jQuery plugin that automatically formats currency and numbers as you type on form inputs. I used autoNumeric 1.9.21 for demo code.

1. Dowload autoNumeric.js file from
2. Import to project
<script src=""></script> <script type="text/javascript" src="js/autoNumeric.js"></script> 3. Define a function to use it
<script type="text/javascript"> /* only number is accepted */ function txtNumberOnly_Mask() { var inputOrgNumber = $("#numberTxt"); inputOrgNumber.each(function() { $(this).autoNumeric({ aSep : '', aDec: '.', vMin : '0.00' }); }); } </script>
4. Call the function by event
<form> <input type="text" value="" id="numberTxt"/>(only number) </form> <script type="te…

Retrospective with Sailboat

Have you ever got bored with the Retrospective meeting? I have, sometime. Most of the times, this meeting just goes traditionally by answering three questions: "What good things have we done? What bad things have we done? And, what actions should we improve?" Ever and ever again! My team found a way to make it a little bit more exciting. The idea is that each member - not only our Scrum Master - will become a host. If a meeting is hosted by a memeber, the next meeting will be hold by another one.

Yeah, I used "Sailboat" pattern in my turn. So, I just want to share with you guys how it was.
I started the meeting by telling a short story that I hoped everyone in my team could recall the meaning behind of Retrospective meetings:
There is a group of people trying pick up trash in a park. At the first look, the park seem not to have a lot of trash because they are spread out all over the place. However, these people continuously found trash when they started. They kept …

Applying pipeline “tensorflow_embedding” of Rasa NLU

According to this nice article, there was a new pipeline released using a different approach from the standard one (spacy_sklearn). I wanted to give it a try to see whether it can help with improving bot’s accuracy.

After applying done, I gave an evaluation of “tensorflow_embedding”. It seemed to work better a bit. For example, I defined intents “greet” and “goodbye” with some following messages in my training data.
## intent:greet- Hey! How are you? - Hi! How can I help you? - Good to see you! - Nice to see you! - Hi - Hello - Hi there ## intent:goodbye- Bye - Bye Bye - See you later - Take care - Peace In order to play around with Rasa NLU, I created a project here. You can have a look at this change from this pull request. Yay!

When I entered message “hi bot”, then bot with “tensorflow_embedding” could detect intent “greet” with better confidence scores rather than bot with “spacy_sklearn”. The following are responses after executing curl -X POST localhost:5000/parse -d '{&qu…
