Kubernetes (also called K8s) remains the most in-demand container for developers. Originally developed by engineers at Google, K8s has achieved global fame as the go-to solution for hosting across on-premise, public, private, or hybrid clouds. Insights from Statista show the Kubernetes market share of the public cloud went from 16% in 2021 to 45% in 2022.

Google’s Core Web Vitals initiative was launched in May of 2020 and, since then, its role in Search has morphed and evolved as roll-outs have been made and feedback has been received. However, to this day, messaging from Google can seem somewhat unclear and, in places, even contradictory. In this post, I am going to distil everything that you actually need to know using fully referenced and cited Google sources.

Fragmentation is a common concern in some database systems. Highly fragmented tables can affect performance and resource allocation. But reducing fragmentation often involves rebuilding the table completely. This blog post will discuss fragmentation and its impact on InnoDB. What is fragmentation? We say that something is fragmented when it is formed by parts that are separate or placed in a different order than the natural one.

There’s a lot of angst about software developers “losing their jobs” to AI, being replaced by a more intelligent version of ChatGPT, GitHub’s Copilot, Google’s Codey, or something similar. Matt Welsh has been talking and writing about the end of programming as such. He’s asking whether large language models eliminate programming as we know it, and he’s excited that the answer is “yes”: eventually, if not in the immediate future.

Performance is one of the essential aspects of a database management system. Very little can be more annoying and frustrating for users than poor performance, meaning long-running queries and high response times at the front end. One of the most effective ways to tackle performance improvement is having the proper indexes for the table columns. An index can save a lot of time in data access and lead the queries to gather the results the fastest way possible.
