Journal: This Month I Learned (2023-April)

I learned that it's important to take breaks and practice self-care to avoid burnout. It's also important to communicate with colleagues and managers about workload and prioritize tasks accordingly. Finally, getting hands-on experience with different aspects of the business can be valuable for personal and professional growth.

OKRs review

The results of the OKR review should not directly impact performance appraisals. Key Results should be straightforward measurements of Objectives, not just a to-do list. They should also be related to daily work, rather than separate topics.

There are two ways to review objectives: "Completion" or "Rating".

The status should be balanced among objectives and used to adapt to current efforts.

Member reassignment

How to find a good fit between business and personnel growth:

Salary costs increase year by year.
It doesn't make sense to increase customer billing year by year.

Burnout counter: Engagement

I engage to work closely with development teams on several specific topics:

Designing databases with fine-tuned data types
Supporting the Product Manager in auditing the product preparation
Reviewing code

However, it's still important to dedicate time to strategic topics and prioritize tasks.

Get your hands dirty

One responsibility as an engineering lead is to support pre-sales by providing quick, rough estimations. Additionally, I need to understand how the product operates in the production environment. Therefore, I sometimes support product operation teams with configuration management. This takes time and requires practice. When I am doing many things in various contexts, I can easily become stressed.

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...

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...

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<...

Gzip upload on browsers

Today, I faced a problem that I could not upload my archive file with gzip format on Firefox, even it worked on Chrome. I was using macOS. My application had a setting to whitelist accepted files. I’ve already added "application/gzip" to that list. "It’s strange!", I thought. I finally figured out that my uploaded file's type actually was "application/x-gzip" on Firefox. I also asked my colleagues to check their uploaded files on Window and Ubuntu. Hmm… they were totally different! It was "application/x-compressed" on Window, and was "application/x-compressed-tar" on Ubuntu. In fact, gzip is already standardized by IANA. There is a note in RFC-6713 as below: "Some applications have informally used media types such as application/gzip-compressed, application/gzipped, application/x-gunzip, application/x-gzip, application/x-gzip-compressed, and gzip/document to describe data compressed with gzip. The media types defin...
