Latest post is a big one: "Why you shouldn't invoke setup​.py directly"

A lot of people don't know about this because we haven't been great about getting the word out. This blog post is in part an attempt to remedy this.

Please help spread the word!

From the archives of my blog but still very relevant: "pytz: The Fastest Footgun in the West", about why you probably shouldn't be using pytz:

I wonder who I know that knows someone at HackerOne that can convey the message that PyPI explicitly disallows security research packages, and bans users who upload them. Put that in a notice to your users somewhere prominent - since it's become pervasive and a drain on resources.
This also takes time away from legitimate security incident response - so it's a net negative for the world.

I think from now on every time I see a "YouTube face" thumbnail with some clickbait nonsense title, I'm going to click and bounce immediately. From my understanding this hurts the algorithm ranking more than my normal strategy of not clicking at all.

TBF, looking at these spires, they wouldn't be entirely wrong...

Real reason it took so long to complete the Sagrada Familia: architect wanted to be long dead before any architecture certificate critics could use the line, "Gaudí? More like gaudy"

You still have several hours left to nominate someone as a PSF Fellow for Q2 of 2026 python.org/psf/fellows/

I'm giving a lighting talk about gh-profiler this evening. If you've been curious about it, come to the lightning talk session at 5:45!

#PyconUS

Look, last-minute Łukasz at #pyconus reporting here that there is a last-minute talk on Sunday at 2:30pm worth attending!

PEP 810 co-author Brittany Reynoso will be talking about lazy imports!

This talk reminds me of these gorgeous floppy disks I got from pizzelpodcast.com

There's a long and interesting story behind these, but each of those disks has an hour-long podcast on it.

One of them also has an audio player for the format that the podcast is encoded in, plus a 15-minute bonus podcast, plus some extras.

It is seriously impressive. I'm planning to have them framed.

Can't believe there is a laser cats themed slide here and I chose the wrong loud Hawaiian shirt to wear today!

Really shocked that flask and all its dependencies fits on a floppy disk TBH.

Not even remotely surprised that @psobot gave yet another amazing talk this year.

I'm super excited to talk about the Rust for CPython project at 1:45PM today in Room 103ABC.

Hope to see you there!

Upwards of 5 people in this room running their code with DeprecationWarnings on Python

Strongly agree with @geofft about testing against Python betas!

Apparently there is a Hot Topic across the street from

I don't think I would have predicted in the 90s that Hot Topic would outlast Radio Shack.

Juggling open space today at 3:45 (start of the afternoon break) in the hall outside room 103.

Join us, we will teach you! No one has ever regretted it!!

#PyCon #PyConUS

Charging my headphone and my phone so i can experience Pablo Galindo's keynote at #pyconus on Sat May 16 @ 9 a.m. with all the fun audio translation!

I'm speaking at PyCon US tomorrow! Come learn why the PyLadiesCon team said "No more spreadsheets" and what we've been building instead using Python and Django.

#Python #Django #PublicSpeaking #NoSpreadsheet #PyConUS

I don't speak much Spanish, but today I still get to help at Las Charlas track as a session chair, and I also staffed at the Python en Español booth because they didn't have enough volunteers.

Thankful for this opportunity.
Thanks to Denny Perez and Andres Pineda who reviewed my Spanish pronounciation beforehand!

Everyone skipping this talk is missing out. Another banger from @mahmoud.
