I have decided it was time for me to gather my Master’s thesis notes and publish a blog post about it. Introduction to Codon Usage Optimization Problem All living organisms are made up of cells, which can group together to form tissues and organs. From biology, we know that all genetic material is encoded in DNA. Regions on DNA that are transcribed into RNA are called genes. These can be synthesized by the cell into proteins, which are long chains of amino acids....

There are moments when life presents us with opportunities and experiences far more rewarding than sitting down to write a blog. This was one of those times. :) I’m trying to revive this blog by migrating from WordPress to Hugo. Stay tuned!

This week I’ve come across the following stacktrace in a Java application while connecting to a web service over HTTPS. The exception was thrown due to certificate not being valid. The message says that Java is unable to find a valid certification path. But the browser marks the certificate as valid. This happened because the app was running on an older version of Java that did not recognize this root certificate authority (CA)....

Composer is a dependency management tool for PHP that has been around for almost 8 years now, but it’s still not included in the official Docker images. Composer recommends to automate the install using their script. It needs to be downloaded, but the php:7.4-apache image does not contain wget.

I was playing around with Micronaut framework 2.0 which was released a couple of days ago (June 26th) for a personal project, a web service with a REST API. I wanted to use Swagger UI, but Micronaut’s documentation does not cover how to set it up with Maven and Kotlin. It went something like this. Generate a new Micronaut 2.0 project. Add some REST endpoints. Follow the Micronaut OpenAPI/Swagger docs (1....

PHP was the first programming (scripting, yes, I know) language that I learned. I had some experience using and managing WordPress, I also liked its features, and I knew that all my needs would already be covered by some plugin of the WordPress ecosystem. Still, I almost didn’t use WordPress to power my blog. I wanted my blog to be versioned (in Git), packaged in a Docker container, and cloud ready....

After a long time of hesitation, I have finally decided to start writing a blog. In the past years, I have been writing a lot – mostly for work and studies. But I have never had a place where I could share my thoughts, or interesting problems and solutions that I have worked on. All beginnings are difficult, but at least I wrote an introduction post. It’s a start. I will blog mostly about software engineering....
