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.

Git Feature Branch Workflow

Motivator It's important for a team to have an agreement on how the changes of source code should be applied. According to projects and teams size, we will define a workflow or select one from recommended workflows ; the "Feature Branch Workflow" is a candidate. What is it? - One branch "master" for main codebase - Several separated branches for features development Why should we care? - Be super simple and allow each developer works on a particular feature. - A stable codebase (master) benefits for continuous integration (CI) environment - Leverage "Pull request" for Code review How it works? A lifecyle of a feature branch (usually created by a story) 1. Creator creates a new branch from a story. For example: "ABC-1-setup-projects" 2. Creator checkouts the created branch and works on the branch (commits, pushes) 3. Creator has done the feature, he uses "pull request" to merge his branch into branch "master...

Managing JAR files with Apache Maven

Apache Maven (Maven) is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information. Why Maven? Let’s learn about the Maven’s history here https://maven.apache.org/background/history-of-maven.html to understand why Maven is created. There are a lot of useful things that we should use Maven. In my opinion, the most important thing is that Maven solves the problems with managing jar files. It centralizes these files in one place and it is easy to use by declaring dependencies in a xml file (pom.xml). Using Maven to manage JAR files Firstly, I would like to give you an example about using some JAR files without Maven. In my project, I need some JAR files such as SNMP4J.jar, jta26.jar, jgraphx.jar, etc… so I had to search them on the Internet with visiting a lot of websites, download and add these files into my proje...

Introduction to OpenLDAP directory service "A directory is a specialized database specially designed for searching and browsing, in addition to supporting basic lookup and update functions" A directory service can be local, providing a restricted context; or global, providing service to a much broader context. Curlie is a good example of a directory service. LDAP (Lightweight Directory Access Protocol) is a protocol for accessing directory services , specifically X.500-based directory services. OpenLDAP is an open-source implementation of LDAP. Writing system software: code comments I have read Clean Code (by Uncle Bob) and I thought that I should void comments since the code it explains its implementation itself. That is right but not always true. In this post, the author categorized the comments into 9 types. Only "trivial comments" and "backup comments" are the ones that should be avoided. I myself agree with "writing good comments is harder tha...

Junit - Test fails on French or German string assertion

In my previous post about building a regex to check a text without special characters but allow German and French . I met a problem that the unit test works fine on my machine using Eclipse, but it was fail when running on Jenkins' build job. Here is my test: @Test public void shouldAllowFrenchAndGermanCharacters(){ String source = "ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ"; assertFalse(SpecialCharactersUtils.isExistSpecialCharater(source)); } Production code: public static boolean isExistNotAllowedCharacters(String source){ Pattern regex = Pattern.compile("^[a-zA-Z_0-9_ÄäÖöÜüß áÁàÀâÂéÉèÈêÊîÎçÇ]*$"); Matcher matcher = regex.matcher(source); return !matcher.matches(); } The result likes the following: Failed tests: SpecialCharactersUtilsTest.shouldAllowFrenchAndGermanCharacters:32 null A guy from stackoverflow.com says: "This is probably due to the default encoding used for your Java source files. The ö in the string literal in the J...

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<...
