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.

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: ...

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 .

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<...

When we don't see the sun, we see other stars

What are your motivations for creativity? - I want to make a change. - It makes me happy! It is a need of my mind. How to be creative for a thing? There are two steps: - See the thing as every people see it - Think about a new different thing from it How to think about a new different thing? There are two ways: - Forget all things you have already known. - A whack on the side of your head. ;) This was what I have learned from the following great book: source: Amazon.com Well! A physical whack on the side of your head is needed sometimes but the meaning behind is that you need to break these 9 following locks on your mind. Remove them! The lock #1: "The correct answer" We all learn from schools that there is only one correct answer to a question. For example, a proposition is only true or false in Algebra. In reality, there are always some answers to a question basing on a point of view. For example, number 6 becomes number 9 if you look it ...

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...
