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.

Make simple music program with beep(freq, duration) with Pascal

Pascal is my first programing language when I have studied in high school. It was really exciting for me. :) The Pascal programming language was created by Niklaus Wirth in 1970. It was named after Blaise Pascal, a famous French Mathematician. It was made as a language to teach programming and to be reliable and efficient. Pascal has since become more than just an academic language and is now used commercially . I tried to make a simple music program by using Lazarus IDE on MS Window 7, 64-bit. It frustrated me a few times how difficulty to use Sound command to make a sound. Sound did not work on my compiler and my platform anymore. So far, I just could use beep(freq, duration) from window unit to implement my work. Here is my code. ;) program mysong; uses Windows, crt; const C: Integer = 512; { x = A * EXP(LN(2)/12)} C_: Integer = 542; D: Integer = 574; D_: Integer = 608; E: Integer = 644; F: Integer = 682; F_: Integer = 723; G: Integer = ...

How Would You Answer These Typical Interview Questions?

I have joined several job interviews with candidates at my current company. As a technical supporter, my attention was mainly focused on specific technical points rather than behavioral ones. However, I saw that these following typical questions were rarely missed for any interviews. In fact, there is a meaning behind of the questions. The concern is candidates should focus on answering the right things that interviewers really want to know. Take a look! Introduce about yourself It is "What and why are you fit for this job?". So, it is good to go "Talking too much about your hobbies."? I would say "We don't care about your hobbies much". ;) Why do you want to find a new job? It is "Why this job are interesting you?". So, it is good to go "Talking about something negative like 'I hate my boss/leader'"? I would say "Who wants to work with a negative person?" What did you do in your current j...

Automating deployment and managing apps on OpenShift

Previously, we maintained OpenShift templates for deploying apps in development environments as well as delivering these templates to our customers for their on-prem deployment. Customers who refer to our templates (as well as documentation) have their own configuration management tools to automate the deployment such as ArgoCD and FluxCD. My son's buildings Our developers usually modify templates (YAML) directly on OpenShift for testing and then adjust the corresponding templates stored in the Git repository in Bitbucket. This sometimes causes an issue that delivered templates are incorrect because: - Developers forget to update the templates in Git repositories. - Developers don’t test the templates Therefore, our goal was to integrate a tool into our CI/CD that can automate and manage the configuration of OpenShift apps. The delivered templates should be the ones that are able to run on our OpenShift with the following purposes: - Automate deployment from templated in Git repos...

Using Drools to Dynamically Manipulate Metadata of JSF Components

The post is just an approach to change metadata (e.g maxlength, required, etc) of JSF components (e.g. inputText, selectOneMenue, etc) by Drools. Project structure Tools being used Java version 1.8.0_131 Apache Maven 3.5.0 Apache Tomcat 8.0.16 Don't forget to configure your confidential information on these following files: pom.xml, settings.xml (Maven) and tomcat-users.xml (Tomcat).

Sharing a virtualenv across several Python projects using Pipenv

There is a standard library for all projects in Python. However, several projects don’t always have the same dependencies all the time. That is where virtual environments come to play. You can follow this official document to use two separated tools virtualenv and pip to fulfill that need. My preferred alternative is to use pipenv . Pipenv is easy to use and convenient. The following are my steps to make a shared virtualenv for my all projects which requires the same dependencies. Step 1. Create an isolated virtualenv. python -m venv my-shared-env Step 2. Create a symbolic link to the created virtualenv. cd project_1 ln -s ~/.local/share/virtualenvs/my-shared-env .venv I have encountered the following issue at step 1. FileNotFoundError: [Errno 2] No such file or directory: '{my_project_path}/.venv/bin/pip': '{my_project_path}/.venv/bin/pip' The root cause was I tried to create virtualenv by running pipenv install and renaming the generated virtualenv to ...
