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.

  1. Holy crap! but, it was cool. Algorithms can be called as "Chi" in Kung Fu!

Coding Exercise, Episode 1

I have received the following exercise from an interviewer, he didn't give the name of the problem. Honestly, I have no idea how to solve this problem even I have tried to read it three times before. Since I used to be a person who always tells myself "I am not the one good at algorithms", but giving up something too soon which I feel that I didn't spend enough effort to overcome is not my way. Then, I have sticked on it for 24 hours. According to the given image on the problem, I tried to get more clues by searching. Thanks to Google, I found a similar problem on Hackerrank (attached link below). My target here was trying my best to just understand the problem and was trying to solve it accordingly by the Editorial on Hackerrank. Due to this circumstance, it turns me to love solving algorithms from now on (laugh). Check it out! Problem You are given a very organized square of size N (1-based index) and a list of S commands The i th command will follow t...

A Template for Software Engineering Standards

Software engineering standard template A well-structured standard acts as a blueprint that guides engineers in their daily tasks and long-term goals. Below, I will outline a template for creating a comprehensive software engineering standard. Header The header serves as the document's identifier. It contains the following: Authors : The people who have contributed to the creation of the standard. Created Date : The date when the document was initially created. Version : The version of the standard. It is typically updated with significant changes. Status : The current status of the document, whether it's in draft, in-review, or official. Next Review Date : The date when the standard will be reviewed for relevancy and accuracy. Table of Contents A table of contents provides an overview of what the document contains, making it easier for readers to navigate through the document. Body The body of the standard comprises: Values : The core beliefs that guide the decision-maki...

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...

What the heck is Meteor DDP?

I was using Meteor for my messenger project. I was so curious about the real time connection. I wanted to know how exactly this mechanism works. In this post, I will go through the DDP Specification, an overview of WebSocket, and a simple demo about how to subscribe a publication of Rocket.Chat (containing a DDP server) from an external webpage. At a glance, I knew that Meteor invented a protocol called DDP which uses for handling real time connection. So then, what is DDP? "DDP (Distributed Data Protocol) is the stateful WebSocket protocol that Meteor uses to communicate between the client and the server." [1] All right! Why does DDP matter? "DDP is a standard way to solve the biggest problem facing client-side JavaScript developers: querying a server-side database, sending the results down to the client, and then pushing changes to the client whenever anything changes in the database" . [2] In order to understand deeply the protocol, I decided ...

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 ...
