Add your name and email to our friends of the show list, we'll never share it. Brian #1: How to Write a Git Commit Message Chris Beams7 rules of a great commit message Separate subject from body with a blank lineLimit the subject line to 50 charactersCapitalize the subject lineDo not end the subject line with a periodUse the imperative mood in the subject lineWrap the body at 72 charactersUse the body to explain what and why vs. howArticle also includes Why a good commit message mattersDiscussion about each of the 7 rulesCool 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 MellströmLike a more modern NGINXCaddy 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 packagingAuthor: 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 3.14Author: 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) Powered by uv for fast dependency managementUse uvx to run jupyterlab with ephemeral virtual environments and tracked dependencies. Extras Brian: Status of Python versions new-ish formatUse this all the time. Can’t remember if we’ve covered the new format yet.See also Python endoflife.date Same dates, very visible encouragement to move on to Python 3.13 if you haven’t already. Michael: Python 3.13.3 is out..git-blame-ignore-revs follow up Joke: BGPT (thanks Doug Farrell)
