Connecting to a Coral TPU Dev Board with Windows
The Coral Dev Board is a TPU-enabled development board for testing out machine learning models with a requirement for near-real-time inference. For instance, image classification or object detection on video feeds, where a CPU would struggle to keep up.
Updating Kubernetes Deployments on a ConfigMap Change

From Firestore to BigQuery with Firebase Functions
In building my sentiment analysis service, I needed a way to get data into BigQuery + Data Studio so I could analyze trends against pricing data. My service (on App Engine) uses Firestore as its primary data store as an append-only log of all analysis runs to date.
Windows Subsystem for Linux w/ zsh, tmux & Docker
I recently put together a Windows machine for gaming, and although I still do most of my development on macOS due to a great third-party ecosystem, BSD underpinnings & better programming language support, I decided to see what development life was like on Windows in 2018.
