A while ago, I wrote a post called How to Create a Dual-Mode Cross-Runtime JavaScript Package: How to Create a Dual-Mode Cross-Runtime JavaScript Package, and while possible - it sure isn't simple. There has to be a better way, and the creators behind jsr.io seem to agree.

So, there I was, diving into Deno's new feature, Deno.cron, when something caught my eye. It was missing a few things – support for time zones, second granularity, and some extended cron-syntax I like. It got me thinking: could I fill these gaps? Despite not having dabbled in Rust before, I had a fair bit of fun creating the croner library for JavaScript and TypeScript, so why not give it a shot in Rust?

Today, I have an exciting CSS trick to share. When working on Lumocs, I wanted users to be able to set a color of their choice and have the page automatically adapt to that color. I had the idea of using CSS variables to achieve this. Lumocs supports both light and dark modes, so this had to be automatic as well. After some tinkering, I discovered a technique that enables you to generate a full color palette using any hue for both light and dark modes using only CSS.

Meet Lumocs, a documentation generator powered by JavaScript through Deno and Lume. This guide will walk you through the essential steps to set it up, create your first documentation page, and deploy your site.

If you want a quick showcase, check out the Lumocs Documentation, which is generated by Lumocs itself.

Planning to host your Deno service or server on your own but unsure about how to launch it at system boot and ensure its uptime? This guide is here to help. Dive into Docker and Pup as robust options for managing Deno apps at system boot, guaranteeing their continuous operation, resilience, and monitoring.

With the constant rise of online threats, it becomes more crucial to ensure that your server is secure. Review these basic measures, and make your server safer. The steps in this guide are primarily geared towards Ubuntu and Debian, but the fundamental principles are the same.

Vanilla JavaScript, in its pure and authentic form, enables developers to utilize the language's native capabilities, freeing them from the confines and redundancies of libraries like jQuery and Lodash. This article reveals the elegance of such native alternatives and advocates for purity in coding practices.

Delve deeper into the creation and management of SSH keys, learning about passphrase protection and the differences between public and private keys.

SSH keys are cryptographic keys that enable user authentication to servers, providing a secure alternative to traditional passwords. They not only increase security but also greatly simplify daily tasks for developers.

Explore the various methods for distributing and utilizing SSH keys, ensuring secure and seamless access to remote servers and GitHub.

Venture into advanced SSH key management concepts such as SSH Certificate Authority (CA) and learn how to set up and manage it manually.

In the ever-evolving world of JavaScript runtimes, Bun is emerging as a promising star. It might not have the maturity of Deno or Node.js, but it compensates with promising great performance. Let's explore Bun in detail.

Following our recent deep dive into the feature sets of JavaScript runtimes, I decided to put them to the test in terms of raw performance. I created a new benchmarking tool called jsrbench to provide a clearer picture of the performance of Deno, Bun, and Node.js under equivalent conditions. I also use another of my tools called primer to compare performance of prime number calculation using different approaches.

Choosing a JavaScript runtime for your project? Then you've probably heard of Deno, Bun, and Node.js. They are all good, but each has its own set of features and trade-offs. This guide will break them down by features, ease of use, security, and other considerations.

Now that we've got our frontend ready, it's time to dive into the game mechanics. In this article, we'll focus on implementing the main loop and single-player mode. We'll walk you through the server-side calculations that make the game tick. You'll learn how the game board updates, how rows are cleared, and how the game state evolves. By the end of this article, you'll have a functional single-player mode and a deeper understanding of the server-side logic that powers it. Let's get those blocks falling!
