Image Courtesy of SiFive, Inc. I recently picked up the SiFive HiFive 1 Rev B RISC-V microcontroller on Crowd Supply. According to the SiFive product page, the HiFive 1 Rev B is “an Arduino-compatible development board featuring the SiFive Freedom E310-G002 (FE310-G002) SoC plus a ESP32-SOLO-1 Wi-Fi and Bluetooth module”. I have seen examples for this board written in C, Rust, and TinyGo. Having not used Rust as much as I would like, I wanted to start there for development on this platform....

Context Recently, I was tasked with logging error messages, request data, and the response body of failed HTTP requests to BigQuery for a service that makes outgoing GET and POST requests to thousands of different endpoints. Simple enough, right? Loading Logs into BigQuery Thankfully, the project already contained a legacy BigQuery streaming implementation which I used as my batch writer. After a thorough review of the changes, it was deployed to production....

Ansible for the Homelab It’s been a while since I last posted. Well, I’ve been working on something special. With my first server (an HP laptop with a broken screen) being nearly five years old, I was rapidly growing concerned about the health of it’s battery. The laptop has been plugged in and “floating” at 100% for the last 3-4 years. Given it’s previous life as a daily driven laptop (~7 years of total use), I assumed one day in the near future it would decide to become a spicy pillow....

ZSH! Below you can find the setup that I’ve found very comfortable while still maintaining a relatively minimal terminal experience. Confidential environment variables and aliases have been omitted to maintain basic operational security. This post will be edited every time a major revision is made.

Introduction In a few cases while working on Go software, I have needed to generate a cryptographic hash (mainly SHA-256) from a string or JSON value. In all cases up to this point, I needed to convert the resulting []byte to a string representation for storage or viewing. In my investigation, I found two popular ways to approach this problem. I’ll describe them below as well as explore the performance implications of each choice....
