My 2017 Review

Passion for System Design

After finishing a one year project, my longest stable team (lasted for 3 years) was separated into two smaller teams. Sadly, but that was a good chance for me to become a key member in my new team. My preferred skills were about system architectures; therefore most of the tasks of building the application structures were handled by me. In order to enhance my design system skills, I have spent much my time for reading books closely after work. These following books help me a lot.
- Object-Oriented Thought Process | Matt Weisfeld
- Head First Design Pattern | Elisabeth Freeman and Kathy Sierra
- Java 8 in Action: Lambdas, Streams, and Functional-style Programming | Alan Mycroft and Mario Fusco

Junior Technical Architect

I was requested to join a technical architect team (aka Team. Alpha) where I actually had gained experiences almost on interviewing candidates for my company (lol). Besides, I noticed myself must improve the skills of convincing people because I had had a strong debate with other members once in a sharing session (yes, I failed). It was really tough to convince others when introducing a stuff/an idea was totally new. But, "Do it Anyway" because debating makes problems clear.


New MacBook

This was something very normal but I think it's worth the money for tackling a new experience on a new operating system (macOS). I really loved it!

Facing challenges in finding a new company

I had worked at my old company (Axon Active Vietnam) for more than 4 years. It was not too long but I felt that it was the time for me to move out of my "safe zone". I had spent much time for interviewing to select a company for my new journey. Sadly, I had failed in a lot of places, from Outsourcing to Product to Startup companies. It was really a frustrated decision but eventually, I made a resignation when I didn't have a new offer. And, even my manager who also suggested a raise to keep me on my team. I appreciated that.

Fortunately, I had received several offers (exactly 3) at the end days before I left my old company. The following was my log: (Company | Applied position | Interview Notes)
  1. NVG | Senior Web Java Developer | Various questions about frameworks are being used.
  2. LenderRate | Developer | Algorithms (level: hard, difficult).
  3. ContentNet | Senior Developer | Deeply technical questions about Java core, design patterns and how to approach a technology.
  4. Absolute Vietnam | Developer | Deeply technical questions about Java core (but, it's my strong points).
  5. Innotech | Full-stack developer | Behavior questions (quickly, only <30 minutes).
  6. FPT | Developer onsite longterm in Singapore | Specific frameworks (Restful API, NodeJS, Microservices).
  7. Adnovum | Professional Developer | How you understand your most favorite projects and used technologies; algorithms (level: easy/medium).
  8. Freelancer with my beloved team | So, I passed it without conditions (Haha).
  9. Politely declined to interview at Zalora, SAI GON BPO.

Winning my first project with my freelance team

With a strong spirit of a startup, my team focused on trying to make our first project super succeed by providing a good quality and fast-building application. It was not only collaborating well with customers but consulting them to have a "better" application.

The following were key values of my team:
- Having the same vision: sharing a "can do" attitude. We organized some practical sessions each sprint such as knowledge sharing, code reviewing, and retrospective.
- Focus: reflection and adaption on whole sprint goal, not individual tasks status.
- Being agile: being flexible/effective at work rather than following strictly a process.

Happy New Year! 2018.

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: ...

Java Core - Top 10 Questions Every Developer Should Know

#RandomlyPickedByMe What is the difference between Javascript and Java? Difference between StringBuilder and StringBuffer? Why do I get "SomeType@a3fde" when I print my code? Why is String immutable? Why "equals" method when we have "==" operator? Is List<Dog> a subclass of List<Animal>? Why shouldn't we use raw type? Is Java “pass-by-reference” or “pass-by-value”? What's the advantage of a Java enum versus a class with public static final fields? Why "double x = 0.1 + 0.2" and result of print(x) is 0.30000000000000004? 1. What is the difference between Javascript and Java? Holy crap! (Vietnamese: Thế quái nào lại có câu hỏi ngớ ngẩn vậy chứ?) "Java and Javascript are similar like Car and Carpet are similar." - Greg Hewgill (on StackOverflow) 2. Difference between StringBuilder and StringBuffer String is immutable. StringBuilder and StringBuffer are mutable. StringBuffer is thread-safe. String...

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 ...

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...

Fulfilling Your Contribution Needs

Human resource management motivation Managing human today is quite different from the industrial age which treats people as just "chickens". Rather than people now are very important to the success of an organization. People are an organization's special resource. They should be encouraged to grow to contribute their effort and creativeness to their beloved working environment because the contribution is one of their most needs in life. Training people: getting rid of the ineffective model and adopting the new one The ineffective model of training people: Hiring new people --> giving them a crash course once --> expecting them working effectively.  That somehow makes sense but you're about to expect a luck because you do not really spend your effort for mentoring them. If they can work effectively, well...lucky you! Otherwise, you will blame that these people are ineffective and you let them go and hire the new ones. What a waste of time! The new effe...
