**TDD: Test-Driven Development vs TAB-Driven Development**

The rise of AI-powered coding assistants is changing the way we approach code completion, often allowing us to accept suggestions with a simple press of the TAB key, significantly speeding up our workflow. These tools can even generate the necessary tests automatically.

In this context, is Test-Driven Development (TDD) becoming obsolete? Or does the practice of using tests to drive the design of our applications still hold substantial value in the age of AI? Let's explore the evolving landscape of software development and look at the ongoing relevance of TDD in an AI-enhanced world.

**Making sense of Vector Databases**

Vector databases are quite a hot topic these days. From powering semantic search to recommendation systems and from anomaly detection to clustering, all of this can be achieved with vector databases. But how do they achieve this? Join this talk to find out.

We start with a simple mathematical representation of a vector and gradually add more concepts to this representation. While we do that we start with a simple example of how vectors can be used and make the examples ever so complex each time we add a new concept to it. Finally taking the examples to an incredibly amazing level!

All in all, this talk will introduce vector databases while explaining the fundamental concepts behind it. It will explain what vectors are, how are they stored, what are embedding models, indexing algorithms and similarity/distance metrics. While we do this we also create a tiny vector database using Java’s Vector API.
