I have recently received an email from GitHub asking me to confirm my SSH key. It took me a while to figure out how to generate the required fingerprint from the saved key file. Here is what needs to be done:
ssh-keygen -lf .sshid_rsa.pub 2048 8d:f4:e7:95:76:b4:3d:5f:49:ec:49:79:50:8a:be:91 ..sshid_rsa.pub

Apache NiFi does a great job when it comes to data flow automation. It excels in many regards – ease of use, built-in processors of all kinds, straightforward debugging or data provenance, to name but a few. Despite of a fairly moderate learning curve, there surely are new concepts to grasp. It took me a while to understand…
Here is how to setup a JEE dev box with VirtualBox and Vagrant.
Less unit test code doesn’t necessarily result into poor coverage. I’ve recently entered the paradigm of parameterized tests when refactoring a larger test suite. I ended up writing significantly less code without compromising on the extent. In fact, adding a few corner cases was almost a no-brainer. In this post I’d like to share my…
Copying files in Gradle is very intuitive. It’s easy enough to filter out unwanted files using the exclude pattern. Example (see documentation): task copyTaskWithPatterns(type: Copy) { from ‘src/main/webapp’ into ‘build/explodedWar’ include ‘**/*.html’ include ‘**/*.jsp’ exclude { details -> details.file.name.endsWith(‘.html’) && details.file.text.contains(‘staging’) } } The problem occurs, when you only want to copy specific files and…
Grep4j caters for an easy search in log files. Since it is really easy to use and simple enough I could not resist the temptation to try it out. I came up with a simple scenario: Let’s use Spring MVC to conduct a small JSON-based web app, capture the exchanged requests and responses in a…
When managing multi-tenant systems, one common anxiety is that a coding error can unintentionally expose user data. Incorrectly routing a user’s data to the wrong tenant, or even distributing it to another user within the same tenant, is a very real fear. Additional precautions are necessary to safeguard against human errors. Supabase is an open-source platform that offers a viable alternative to Firebase. Similar to Firebase, it provides a frictionless user authentication process. Due to its integration with Postgres, it supports sophisticated access controls at a row level, aptly referred to as Row-Level Security (RLS). In this article, we’ll explore a concrete example of leveraging this feature and provide step-by-step implementation guidelines.
