BarcampSaigon 2015


Barcamp Saigon is one of my most expected events of the year. This year, it took place at RMIT university. As usual, it brought many useful topics to the community. Here is all topics that I have attended.

Scale it! - Lars Jankowfsky

Lars is founder of 8bitrockr.com

How do we make a decision correctly? It is hard to know that until we try and measure it. He gave an example about how good an app was. And, most of people thought that the app with nice user interfaces is good at the first look. But it is not correct because it is only true until we try to use it, even the nice GUI app sometime is not good at UX, functionalities, etc.

The key of success for working in team is collaboration. We can not only base on the experience of members likes: "In my opinions| As I know.... this is the best way..bla..bla.." but we should test it. Therefore, manually testing as well as automation testing is more and more necessary nowadays.

"Don't think, just try" - he said.

Shelfout - Chia sẻ sách và đam mê đọc sách - Nguyễn Trọng Tín.

Nguyễn Trọng Tín is founder of shelfout.com. His idea is about creating a community in order to sharing books. He saw that 81% of book is not used again after it is already read once and he called it is waste. He has already found some existing systems like goodreads.com, Facebook groups but they are not satisfied his expectations. By shelfout.com, he wants to connect all people with passion on reading and books can be used more effectively.

Learn or Die? - Lars Jankowfsky.

Once again, he gave a question "If I want to build an app, which programming language should I use?". Actually, we are not sure. He provided some information from surveys and statistic that shows a lot of languages can be used and the popular one is different from region. So, we should be flexible base on what we know. The world always changes and we should learn to update our knowledge.

IoT How developers can get money - Thanh VNG.

Thanh is working in VNG, Vietnam. IoT (Internet of Things) is a bit trend today. Therefore, developers can have a big chances to work and earn money from that.

Why your proposal was ignored? - Soshi  Nemoto.

Soshi is from Molodo Vietnam. Your proposal should be logical.

About Barcamp Saigon:
"BarcampSaigon is an unconference that was created in the tech community in 2005. Organizers of the event only organized the space and the people from the community were the presenters"

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<...

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

Check out my implementation here 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 Rocket.chat'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 glance rasa-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 too...

Styling Sort Icons Using Font Awesome for Primefaces' Data Table

So far, Primefaces has used image sprites for displaying the sort icons. This leads to a problem if we want to make a different style for these icons; for example, I would make the icon "arrow up" more blurry at the first time the table loading because I want to highlight the icon "arrow down". I found a way that I can replace these icons with Font Awesome icons. We will use "CSS Pseudo-classes" to achieve it. The hardest thing here is that we should handle displaying icons in different cases. There is a case both "arrow up" and "arrow down" showing and other case is only one of these icons is shown. .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s { background-image: none; margin-left: 5px; font-size: 1.1666em; position: relative; } .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s:not(.ui-icon-triangle-1-s)::before { content: "\f106"; font-family: "FontAwesome"; position: ...

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. KanbanFlow 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  iTerm ,  oh-my- zsh , and  thefuck . ;) iTerm + oh-my-zsh 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...

The power of acceptance test

User Story is the place PO gives his ideas about features so that developers are able to know what requirements are. Acceptance tests are these show the most valuable things of the features represented by some specific cases. Usually PO defines them, but not always. Therefore, refining existing acceptance tests – even defining new ones that cover all features of the User Story must be a worth task. Acceptance test with Given When Then pattern If we understand what we are going to do, we can complete it by 50% I have worked with some members those just start implementing the features one by one and from top to down of the User Story description. Be honest, I am the one used to be. What a risky approach! Because it might meet a case that is very easy to miss requirements or needs to re-work after finding any misunderstood things. I have also worked with some members those accept spending a long time to clarify the User Story. Reading carefully of whole User Story by defining...
