Dockerfile for creating a Datasette of NHS dentist information (via) Really neat Dockerfile example by Alf Eaton that uses multi-stage builds to pull dentist information from the NHS, compile to SQLite using csvs-to-sqlite and serve the results with Datasette. TIL the NHS like to use ¬ as their CSV separator! # 2:09 pm
Smaller Python Docker Containers with Multi-Stage Builds and Python Wheels (via) Clear tutorial on how to use Docker’s multi-stage build feature to create smaller final images by taking advantage of Python’s wheel format—so an initial stage can install a full compiler toolchain and compile C dependencies into wheels, then a later stage can install those pre-compiled wheels into a slimmer container without including the C compiler. # 2:05 pm
Hello world for ASGI running on Glitch (via) I’m continuing to experiment with Python 3 running on Glitch. This evening on my walk home from work I built this “hello world” demo on my phone, partly to see if Glitch was a workable mobile development environment—it passed with flying colours! The demo is a simple hello world implemented using the new ASGI 3.0 specification, running on the daphne reference server. Click the “via” link for my accompanying thread on Twitter, which includes a short screencast (also recorded on my phone) showing Glitch in action. # 5:06 am
