What the heck are iterators and generators and how to effectively code with these concepts in JavaScript.

Reactive programming with WebFlux allows us to scale vertically up, from within the VM with small independent threads. This means that its producers don’t overwhelm consumers. In this article, we will go through the implementation of two Spring boot services. One will be implemented with the old MVC model and the other with a new Webflux model.

Reactive programming is a declarative programming model or programming paradigm. It is mainly concerned with the handling of asynchronous data streams. In this article, I will go through problems found along with implementing reactive programming and the possible solutions. At the bottom of the tutorial, we will find the most plausible solution I found for the case I’m presenting.

CQRS is a software architecture designed to mitigate known caveats of 'Object-Oriented architecture' Writes and reads generate, almost all the time, a very different load against the system. The point is always to keep read operations apart from write operations.

Ports and Adapters architecture was created by Alistair Cockburn in 2005. It is one of the many forms of DDD(Domain Driven Design Architecture) The idea is to separate the application we want to develop into essentially three separate parts. Inside is the business logic and the application itself and outside is whatever we are using to connect and interact with the application.

Integrating Large Language Models (LLMs) with diagramming tools like Mermaid and UML is revolutionizing software development. By providing a textual description to an LLM, the model can generate the corresponding Mermaid code for a flowchart.

These tools will help build a hiring system, not just make a random hire once in a while.

Window functions are a powerful feature in SQL used to perform calculations across a set of rows related to the current row. Unlike aggregate functions, window functions do not group rows into a single output. They return a result for each row while maintaining the context of the dataset.
