Web workers in ReactJs
A web worker is a JavaScript feature that allows you to run scripts in the background. This background execution enables you to perform tasks concurrently without blocking the user interface. Web workers are particularly useful for handling computationally intensive or time-consuming operations without impacting the user's experience.

What Is Good Database Design?
DZone: Good database design is essential to ensure data accuracy, consistency, and integrity. The design must address the storing and retrieving of data quickly and easily while handling large volumes of data in a stable way. Data security is a critical consideration in modern database design, given the rising prevalence of fraud and data breaches.

Picking the Perfect Database for Your Microservices
Microservices have been the go-to application architecture that many software projects have adopted. Microservices favour independent service components where each service can run on its own runtime and connect to its own database. This means you're encouraged to share data between microservices rather than using an extensive single database for all your microservices.

Can you fix 2,500 TypeScript errors?
Inkdrop mobile v5.1.0 beta is available on the beta version on TestFlight and Google Play Store. The app used to freeze for a few seconds when changing device orientations on tablets. I realized that this was caused by a massive amount of UI rerendering due to the window dimension change event.

How to Effectively Use Caching to Improve Microservices Performance
Caching is a technique used in computer systems to store frequently accessed data or computation results in a temporary storage area called a "cache" This article will dive into the art of leveraging caching techniques to their fullest potential. We will explore database caching, edge caching, API caching, and local caching.

Exploring Million.js, a high-performance web framework
Million.js is a minimalistic JavaScript framework designed to handle DOM elements efficiently. Million.js uses a granular approach by updating only the necessary parts of the DOM. The Block virtual DOM is based on the concept of Blockdom, which facilitates virtual DOM diffing for re-rendering the actual DOM.

Bun: lessons from disrupting a tech ecosystem
Two weeks ago, a JavaScript runtime and toolkit called Bun was released and took the Node.js world by storm. Its top focus is performance, and according to benchmarks shared in the launch video, around 10x performance increases can be observed when building packages, running code, or handling inbound requests on a server.

PostgreSQL Performance Tuning, Part II: Key Parameters
The ‘max_worker_processes’ parameter determines the maximum number of worker processes you can start. The default value is two, but somewhere around a quarter to a half of your CPU count is a good option. In Timescale, we start at two and progressively increase it as your CPU increases to match half your CPU.

My thoughts on Bun and other Adventures
Bun does not support Fastify or Pino, with pino being as popular as Next.js. In my experience, it's not a drop-in replacement, and many inner details differ. Bun team is actively looking into adding the missing APIs and behaviors, and I expect them to catch up in the coming months.

Mastering Subscription Handling in Angular
The lack of subscription handling can cause many problems in your app, the most critical one is memory leak. Subscriptions are not bundled with the component; therefore, we also need to dispose of subscriptions when the components are being destroyed. To destroy the subscription we created we can use the method on the function we created.
