How did MCP get standardized before a location for prompt files? I'm rather dumbfounded that I can't write a single prompt file for a repo and just have the models all pick it up automatically without some editor-specific setting.

AI failed: paragraph-formatted spec using something introduced in Python 3.12 (Claude Sonnet 3.7 came the closest to succeeding; Claude 4 wasn't out yet)

I was poking around the Mastodon APIs and I can't find a way to have a bot hide individual posts for me, only update my filters list. Am I missing something?

Went through various Pocket replacements this weekend. I wanted a read queue that has strips out superfluous stuff from the page (i.e. not bookmarking, so that eliminated Raindrop, Linkwarden).
I tried:

I just got the "Admired" badge on discuss.python.org, and I'm only the 2nd person after @pfmoore to get it.

I don't know what that says about Paul and me that we have posted over 300 times, let alone that many times with at least at least 5 likes. 😅

If I had a connection in Munich from Canada to Prague and I had 1h45m to make that connection (so I suspect customs and security), is that enough time? It would be on Lufthansa the whole way if that helps.
Otherwise I'm looking at 1h10m in Zurich (seems too short), 1h47m in Toronto (which is a […]

@pauleveritt I just started to listening to the Talk Python to Me episode on t-strings, and I can tell you that according to https://opensource.snarky.ca/About+Me/Appearances , @mkennedy has not found me interesting enough to be on since Dec 2023, so I have 3.5 years left to be boring 😉

I wrote a blog post unravelling t-strings to help explain what they are doing -- providing syntactic access to the f-string parser -- while we wait on the official docs.

Unravelling t-strings
PEP 750 introduced t-strings for Python 3.14. In fact, they are so new that as of Python 3.14.0b1 there still isn't any documentation yet for t-strings. 😅 As such, this blog post will hopefully help explain what exactly t-strings are and what you might use them for by

If you open an issue and use "GPT" as a verb then I'm going to assume your solution is wrong. Not because using AI is inherently bad, but because I'm going to assume you don't understand the problem or solution and you just "prompted" the problem away.
