Brian #1: How to Write a Git Commit Message

Chris Beams

7 rules of a great commit message

Separate subject from body with a blank line

Limit the subject line to 50 characters

Capitalize the subject line

Do not end the subject line with a period

Use the imperative mood in the subject line

Wrap the body at 72 characters

Use the body to explain what and why vs. how

Article also includes

Why a good commit message matters

Discussion about each of the 7 rules

Cool hat tips to other articles on the subject

“Keep in mind: This has all been said before.”

Each word is a different link.

Michael #2: Caddy Web Server

via Fredrik Mellström

Like a more modern NGINX

Caddy automatically obtains and renews TLS certificates for all your sites.

Caddy's native configuration is a JSON document.

Even localhost and internal IPs are served with TLS using the intermediate of a fully-automated, self-managed CA that is automatically installed into most local trust stores.

Configure multiple Caddy instances with the same storage, and they will automatically coordinate certificate management as a fleet.

Production-grade static file server.

Brian #3: Some new PEPs approved

PEP 770 – Improving measurability of Python packages with Software Bill-of-Materials

Accepted for packaging

Author: Seth Larson, Sponsor Brett Cannon

“This PEP proposes using SBOM documents included in Python packages as a means to improve automated software measurability for Python packages.”

PEP 750 – Template Strings

Accepted for Python 3.14

Author: Jim Baker, Guido van Rossum, Paul Everitt, Kaudai Aono, Lysandros Nikolaou, Dave Peck

“Templates provide developers with access to the string and its interpolated values before they are combined. This brings native flexible string processing to the Python language and enables safety checks, web templating, domain-specific languages, and more.”

Michael #4: juv

A toolkit for reproducible Jupyter notebooks, powered by uv.

Create, manage, and run Jupyter notebooks with their dependencies

Pin dependencies with PEP 723 - inline script metadata

Launch ephemeral sessions for multiple front ends (e.g., JupyterLab, Notebook, NbClassic)

Use uvx to run jupyterlab with ephemeral virtual environments and tracked dependencies.
