Lume (pronounced /lume/ 🔈) is the Galician word for fire but also a static site generator for Deno.

It's inspired by other static site generators, such as Jekyll, Hugo or Eleventy, but easier to use and configure and much more flexible.

• You can hook processors to manipulate html and assets, like css or js.
• It's Deno: Forget about managing thousands of packages in node_modules or complex bundlers. Lume only installs what you need. Clean, fast and secure.

I love interactive things, but I’m not a fan of expensive devices, especially those we have to buy year after year to have the latest hardware in our hands!

I’m a fan of accessible technology!

With that in mind, today I’m going to show you how to control elements in a 3D scene using just your hands, a webcam, and a web browser. The key focus here is converting a 2D screen into a 3D space, with full depth control. I’ll keep the focus on that!

To achieve this result, we will use Mediapipe and Three.js.

Most software developers use Git on a daily basis. But how many truly understand Git? Do you feel like you know what's going on under the hood as you use Git to perform various tasks?

For example, what happens when you use git commit? What is stored between commits? Is it just a diff between the current and previous commit? If so, how is the diff encoded? Or is an entire snapshot of the repository stored each time?

Most people who use Git don't know the answers to the questions posed above. But does it really matter? Do you really have to know all of those things?

I'd argue that it does matter. As professionals, we should strive to understand the tools we use, especially if we use them all the time, like Git.
