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.

JSF 2 - Dynamically manipulating the component tree with system events

Let's suppose we want to modify the metadata (attributes)  of elements such as render , requried , maxlength but we do not define in JSF tags. The manipulating components can be conducted in Drools  files, for example. How could we do? I think that is what we need to change something of component tree during JSF life-cycle. JSF supports event handling throughout the JSF life-cycle. In this post, I use two events: postAddToView for scanning components tree and preRenderView for manipulating the meta of components before rendering to GUI. I modified my own project from previous post for this example. This is my first further JSF trying out with the project as I said before. :) We define the tags f:event below the form - a container component of the components which we want to work on. The valid values for the attribute type for f:event can be found from tag library document  of JSF 2. <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" x...

BIRT - Fix the size of an image

I use a dynamic image as a logo my report in pdf. At the beginning, I use table to align the logo in left or right. I meet a problem with some images with a large width or height. My customer requires that the logo should be displayed in original size. These following steps solves my problem: 1. Use Grid instead of Table 2. Set Grid "Height" is 100%  and "Width" is blank 3. Set "Fit to container" for images are "true". Download the the template here .

Google I/O 2017 Notes

WOW! How meaningful this below video explains about the name of  "I/O". Sundar Pichai talked a lot of Machine Learning Machine Learning is a very hot trend these days. Google uses it for their products. Google Assistant: Easily booking an online meal by talking with Google Assistant like a staff of partners, for example. Google Home: Hands-free calling. Google Photos: sharing suggestion, shared library, photo books and google lens. Youtube: 360 degree video, live stream. Kotlin became an official programming language for Android https://kotlinlang.org I'm on the way to Kotlin! ^^ Reference: [1]. https://www.youtube.com/watch?v=Y2VF8tmLFHw

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: ...

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 ...
