My 2022 Review

2022 was completely a mind-blowing year for me. Lots of changes happened at work. At present, things seem to be going to settle down, I want to look back at my year.

My balcony (2022)

Q1

At beginning of the year, I started with Metaverse and NFT research. I completed my first course about a new technology Blockchain on brilliant[dot]com which became my best favorite learning platform later on. Getting a certified IBM developer certification was also a good experience. I gained more knowledge of technologies including containerization, microservices, DevOps, and Cloud-Native. It triggered me to plan for DevOps toolchain enhancement for the company. Adopting GitOps practice was a good start. It is one of my main focuses for my position role as a Tech Lead. I was really impressed by the book “The Brief History of Time”. The story of Stephen Hawking was so inspiring. To me, it was one of my favorite books of this year. Sadly, this period was the time when some of my good friends were leaving the company.

Q2

Changing the organizational process was so truly difficult. Lots of discussions have been conducted to have the same voice for a group of people since the new role Engineering Lead was proposed for the change. What I experienced well in this period was that whenever I put my energy into something, all related things will come around me. And, franking is the only medicine to treat toxic sicknesses and environments. I started to sharpen my English pronunciation skills with ELSA speak app. I also spent time reading human management-related books including “The Mythical Man-Month” and “Peopleware”. I also spent a month interviewing for a new role as an Engineering Manager in a startup.

Q3

The role of Engineering Lead was adopted well. Working with completely new teams with new projects was an excellent experience. I have learned to work with new people who don’t have the same mindset as me. As a leader of the new teams, I understand more about the effortless approach to leading people. Getting the Professional Scrum Master (PSM) certificate helped me set up my working style as a Scrum Master with new teams. I affirmed that I should not be a hero but rather that I need to give more authority to the team to be self-organized.

Q4

Still, there were many things happened unanticipatedly. Another good member was leaving the company. It was the first time I joined team HR to define a process of annual performance appraisal. It took a huge time and effort. Some new practices were officially applied as a company standard such as Engineering Levels, OKRs, and the role of Team Lead. I also have experience with leading some development teams working on different projects built with different technologies. Giving clarity of the projects' roadmap for developers was my important job. Moreover, I have learned along with teams to solve different emerging project issues.

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 ...

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...

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...

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...
