Update firmware WD Black SN770 firmware on Arch Linux

Been having problems with my new SN770 drive, and decided to check if I can firmware update it on Linux. WD only provides a Windows tool, Western Digital Dashboard to download and install firmwares, but, it's possible to find the firmware and install it using Linux tooling as well.

1. Check that `nvme-cli` is installed:

❱ sudo pacman -S nvme-cli

Building a Wireless Bluetooth USB-C Keyboard with ESP32-S3 Mini

Creating a wireless Bluetooth USB-C keyboard using an ESP32-S3 Mini involves connecting a USB-C keyboard to an ESP32-S3 via a USB Host Shield. This project allows you to transform a wired keyboard into a wireless one, leveraging Bluetooth communication. Below is a detailed guide on how to set up and program this system.

Components Needed

ESP32-S3 Mini
USB Host Shield or USB Host Adapter (e.g., USB Host Shield for Arduino or a USB Host Module)
USB-C Keyboard
USB-C to USB-A Adapter (if necessary)

Ollama GPU Selector: Customize GPU Usage for Ollama

If you want to run Ollama on a specific GPU or multiple GPUs, this tutorial is for you. By default, Ollama utilizes all available GPUs, but sometimes you may want to dedicate a specific GPU or a subset of your GPUs for Ollama's use. The idea for this guide originated from the following issue: Run Ollama on dedicated GPU.

Steps:

Create a script let's call it ollama_gpu_selector.sh:
```
nano ollama_gpu_selector.sh
```

How to Hand-Track Polar-Orbiting Weather Satellites

This is how I hand-track polar-orbiting weather satellites using an old equatorial mount telescope tripod and a 1.7 GHz grid dish. This may not be the best way to do it, and other ideas are welcome!

If you're unfamiliar with HRPT reception, this is not the right place to learn about it. Head over to https://sgcderek.github.io/blog/beginner-hrpt-guide.html for that. This write-up only focuses on hand-tracking to record a baseband.

Hardware Required

The crux of the "tracking" design is the equatorial mount. These are not cheap to buy new, it's destructive to mount a dish to it, and the mount is not used the way it's designed - but for my needs, it works! I had an old one from the early 1990s lying around, so it was convenient and essentially free. Of course, you can use another mount - but you'll need to ask for someone else's opinion on how that works since equatorial is all I know 😄.
