Build Your Own Database From Scratch - Persistence, Indexing, Concurrency

Behavioral data describes what customers do minute by minute, second by second. And, because it’s granular, contextual, and explanatory, it provides the strongest predictor of customer intent.

Istio ambient mesh is a mode that leverages a mesh data plane instead of deploying sidecar proxies, without sacrificing zero trust security.

I often get to argument with various linux guys about AT&T versus Intel syntax. There are many things I dislike on AT&T syntax, so I decided to write them all down in this article.

NASA is planning to build a number of infrastructure on the moon, including a human habitat, a new space station—and a web service that can connect it all.

Most of the kernel's code is written in C and intended to be run directly on the underlying hardware. That situation is changing in a few ways, though; one of those is the ability to write kernel code for the BPF virtual machine. The 6.3 kernel release will include a new API making the red-black tree data structure available to BPF programs. Beyond being an interesting feature in its own right, this new API shows how BPF is bringing a different approach to kernel programming — and to the C language in general.

Fourier analysis provides ideas on how to quickly train more accurate neural networks

Last week, I wrote about putting the right feature at the right place. I used rate limiting as an example, moving it from a library inside the application to the API Gateway. Today, I’ll use another example: authentication and authorization. Securing a Spring Boot application I’ll keep using Spring Boot in the following because I’m familiar with it. The Spring Boot application offers a REST endpoint to check employees' salaries. The specific use case is taken from the Open
