In this post, I explore the math behind Prometheus’s deriv() function, which calculates the derivative of time series using least-squares regression. This method estimates the slope of each series in a range vector, as explained in Prometheus: Up & Running, 2nd Edition.

Just finished Chapter 14 of Prometheus: Up & Running, which dives into Aggregation Operators. This chapter covers standard deviation and quantile functions, and as usual, I’m using Python to break these concepts down further for a deeper understanding.

In this blog post, I explore Prometheus subqueries, a powerful feature in PromQL that allows you to run instant queries over a range with specific resolution. After reaching Part 4 of Prometheus: Up & Running, 2nd Edition, I break down subqueries step by step to help you fully understand how they work and how they can be used effectively.

I recently 3D printed the Ulvheim Small Merchant House on my Bambu Labs X1 Carbon, and the results were incredible. The model’s intricate details, from wooden beams to stone textures, were perfectly captured, making it a fantastic addition to any D&D game.

Reading through the book Prometheus: Up & Running, 2nd Edition, highlighting its practical, no-fluff approach even for experienced users.

In this post, I share my early experiences exploring the new Qwen3 model, building on my previous work with the 1.5B parameter Qwen2.5 using Python and Hugging Face Transformers. Despite working with a modest NVIDIA 3060 GPU, I’ve been able to generate impressive results, and now I’m diving into what Qwen3 brings to the table.

As part of my ongoing Blender Creations challenge, I set out to make something playful, functional, and just a bit ridiculous. That’s how Gator Frames were born. The idea started with a simple question: how can I display my trading cards in a way that reflects their personality and mine? Traditional frames felt too serious. So I fired up Blender, prototyped some ideas, and after several iterations and a few test prints, the Gator Frames came to life, complete with magnetic closures, vibrant colors, and a goofy set of gator-style feet.

For this week’s Blender challenge, I decided to take a more technical route. Instead of diving straight into a creative concept, I focused on something practical, processing SVG images in Blender for 3D printing. I’ve put together a short tutorial that walks through my workflow: how I import SVG files, convert them to 3D geometry, clean up the mesh, and get everything ready for printing on my Bambu Labs X1 Carbon.

This week’s Blender challenge was a fun one, and pretty personal too. I’ve been diving deeper into 3D printing lately, with the goal of launching some products on my Etsy store soon. So, I thought it’d be the perfect time to take on a modeling project using a tool that’s already playing a big role in my workflow, the Bambu Labs X1 Carbon 3D printer. I used the printer itself as a reference for the entire process, modeling and texturing everything directly in Blender.

For this Blender challenge, I’m deep in the digital trenches, working on a 3D model of some Warhammer 40K Kill Team terrain—specifically from the Sector Mechanicus range. To kick things off, I pulled an old, hand-painted piece from my shelf, one I finished a couple of years back, and used it as a physical reference. There’s something special about translating a tangible, paint-chipped relic of the battlefield into a fresh, detailed 3D model.
