Data observability is so hot right now...but do you know what's also hot? Using some tried and tested ingredients like Apache Airflow and PyOD to perform painless anomaly detection on your key business metrics. You don't need to run off and buy an (expensive!) subscription for the latest hot data observability Sass offering (there is … Continue reading Painless Anomaly Detection with Apache Airflow
Stripe Webhook + GCP Functions Framework (Python)
This took a couple of days of messing around so decided to make a post out of it. Here is a minimal enough example repo using Terraform and GCP Functions Framework to build a GCP Python function that will receive a Stripe webhook event, perform signature verification, and then just print the event.

Hugging Face Text Classification Quickstart
I have been working a bit lately with some text classification stuff using Hugging Face - its great n all but their docs can actually be a bit overwhelming. So here is a minimal text classification example, using huggingface and either pytorch or tensorflow (you decide). Will try to update and maintain the colab here: … Continue reading Hugging Face Text Classification Quickstart
