Table of Contents Unit Tests Integration Tests Wrap-Up Kafka Connect is a key factor for the wide-spread adoption of Apache Kafka: a framework and runtime environment for connectors, it makes the task of getting data either into Kafka or out of Kafka solely a matter of configuration, rather than a bespoke programming job. There’s dozens, if not hundreds, of readymade source and sink connectors, allowing you to create no-code....

Since jOOQ 3.11, implicit joins have been supported. An implicit join is a JOIN (mostly a LEFT JOIN) that is generated implicitly because of the presence of a path expression. If SQL supported the syntax natively, it would look like this: All that is is convenience for a bunch of explicitly written LEFT JOIN expressions: … Continue reading jOOQ 3.17 Supports Implicit Join also in DML →


In this post, we derive the exact equation for the quantile absolute deviation around the median of the Uniform distribution.

We’re once again at the end of our internship season, and it’s my task to provide a few highlights of what the interns accomplished while they were here.

A guide on how to share the network namespace with another container. This is how a Pod in Kubernetes contains multiple containers. If you’re not working with Kubernetes but e.g. with Docker or docker-compose, this works in the same way pretty much.

In a recent article/tweet the author commented on how all the photos taken by their child looked awful. However they realized this was down to a different generational mindset.

Starting with jOOQ 3.17, the Condition type extends the Field type. Because, that’s what the SQL standard thinks it is, in sorts: The exact definition contains intermediate rules, but you get the idea. A (which is a Condition in jOOQ) can be used wherever a can be used, which again can … Continue reading A Condition is a Field →

Bret Devereaux has long been my go-to source for all things ancient and military history. One thing I somehow missed reading from his incredibly resourceful website is the This Isn’t Sparta series. He recently published a three-year-anniversary series retrospective which promptly surfaced on my RSS feed, giving me a chance to catch up over the holidays. The whole thing is a very long read, with some installments more engaging than others..

While the transition from Drupal 9 to Drupal 10 is expected to be smooth, we can’t ignore security. So, in this article, we’ll explore 5 ways to secure Drupal 10.

Old browsers - seirdy.one - 4 years ago - eng
I added a section on supporting older browsers to my web best practices article. I explain why old browsers are more prevalent than we think, and how to most easily support them. I think the simplest way to do this well is to subset modern standards, not to explicitly use older standards. That is: we should target the subset of the HTML Living Standard that appears in e.g. HTML 5.1, so we get the important corrections in the Living St....

Probably the hardest thing to standardise in SQL is RETURNING data from DML statements. In this article, we’ll look at various ways of doing that with jOOQ, in many of jOOQ’s supported dialects, and with JDBC directly. How to do it with jOOQ Assuming the usual table from the sakila database: jOOQ took syntactic inspiration … Continue reading The Many Ways to Return Data From SQL DML →
