Are you going to #PyConUS? Have you booked in our hotel block? New on the blog, some hard numbers & why we’re in a tight spot. We only have until April 24th to turn the tide, so please read, share, and book your PyCon US stay in the official block today.

Didn’t realize how uncommon it was to self-host an ATProto PDS. Apparently 99.5% of all PDSes are managed by Bluesky itself. There are only a couple thousand independent PDSes, including mine! blue.mackuba.eu/directory/pd...

Amoedi seems… upset! pastebin.com/LS2LpLZ7 That last sentence: “Due to selection effects, [OpenAI employees] are sort of a gullible bunch, but it seems important to push back on these narratives which Sam [Altman] is peddling to his employees.”

Thinking of you, Bruno.

A searing must-read. aphyr.com/posts/397-i-...

Happy k-pop’oween!

I am the very model of an ancient trunkless leg of stone, My shattered visage lies half buried with a sandy sneering frown, The sculptor carved my arrogance upon these broken lifeless things, My name is Ozymandias, the self-describèd King of Kings!

Happy Python 3.14 day to all who celebrate! 🎉 Read about all the cool new bits here: docs.python.org/3.14/whatsne...

It was a beautiful morning for the Lake Union 10K! #Seattle

Hypothesis: every typescript monorepo with a frontend, backend, and shared subpackage has its tooling misconfigured in some subtle but important way.

Do you use Astral's uv? You can try out t-strings easily, today!: > uv run --python 3.14.0b2 python >>> name = "World" >>> t"Hello {name}" Template(strings=('Hello ', ''), interpolations=(Interpolation('World', 'name', None, ''),))

Hard for me to understand technologists with a high p(doom) when everyone *knows* that p(reliable videoconferencing) is epsilon approaching zero.

New financial product wanted: an S&P 499 tracker that follows every company in the index except for Coinbase. Because to heck with them, and to heck with crypto.

Sprint day today! If you’d like to build fun things with t-strings, or to help us write delightful documentation, please stop by room 309! #pycon #pyconus

Morning run to and from Wise County Cafe, a tasty biscuit and bottomless coffee* spot a couple miles from the convention center. * (ask me how I know)

We will do a Python template strings #tstrings sprint tomorrow (Monday) Room 309 at PyConUS @davepeck.org @lysnikolaou.com and Koudai

After the t-strings open space today, a lot of people wondered how they could get in touch/stay up to date. We just stood up a (very preliminary) website with links to resources and contact information. It'll expand greatly between now and when 3.14 launches. t-strings.help #pycon #pyconus

T-strings open space is happening today at 11AM, room 320. Come say hi! #pycon #pyconus

We're holding t-strings open space at PyCon tomorrow (Saturday!) at 11AM If you're interested, come say hello! #pycon #pyconus

For those who use TextMate grammars for syntax highlighting Python (vscode users, for instance!), here's a version that supports Python 3.14's upcoming t-string syntax: gist.github.com/davepeck/e4f... #pycon #pyconus

Latest episode, just in time for #pycon with @pauleveritt.org, @davepeck.org, Jim Baker, and @mkennedy.codes #python #505: t-strings in Python (PEP 750) talkpython.fm/episodes/sho...

If you’re skeptical about coding with LLMs, consider watching Mary Rose Cook’s video building a tiny tactical shooter. She never blind codes; her technical acumen and aesthetic judgment is essential to the outcome. In her expert hands, LLMs are a clear accelerant. maryrosecook.com/blog/post/us...

At breakfast this morning: Me: I’m not very hipster but I *am* hipster adjacent. My wife: I guess that makes me hipster adjacent adjacent. Me: Is that like your hipster Erdős number? Wife: Feels less like Erdős more like Kevin Bacon 10yo, exasperated: ARE YOU SPEAKING IN SOME SORT OF SECRET CODE?!!

As penance for previously sharing my top three Seattle fried chicken sandwiches, I now offer my top three Seattle salads: 1. Serrano Caesar at Pancita -- no joke, this is the stuff of (my literal) dreams 2. Salmon House Salad at Local Tide in Fremont -- a perfect lunch 3. Salad Verte at Le Pichet

The replies to this post are... something. The very online vibe of the past half-year is very reflexively anti-LLM. If we're declaring our allegiance, put me in the Willison-esque "LLM realist" camp. LLMs are weird unpredictable levers with troubling externalities. But I think they *are* levers.

PEP 750, which introduces t-strings to the Python language, has been approved! Template strings are the pythonic parallel to JavaScript's tagged templates. Look for them when Python 3.14 ships later this year! 🎉 peps.python.org/pep-0750/

Thinking they got the whole “everybody swears in Mandarin” thing right on Firefly.

🦀 Hello World! The Rust project now has an official presence on Bluesky! ✨ We'll be posting the same on our Mastodon and Bluesky accounts, so you won't miss anything on either platform.

Heading to Seattle Center. Disappear this chaos.

Excited to see Skylight, a new Seattle startup that makes an ATProto clone of TikTok, climb up the App Store charts. Both because they’re local (to be clear, I don’t know them) and because it’s a well executed example of decentralized usability. Also, love the tagline!

I think this video sums up Trump's approach to the economy reasonably well. www.youtube.com/watch?v=TGIv...

I share this schadenfreude!

Reminder: the ultra-well adopted Prisma ORM for JavaScript-land ("Just use Prisma!" they say on the forums) performed all joins *in memory* for its first many years. If you're building an ORM that is incapable of using the database for joins... I mean, 🤦🏻‍♂️ This is the madness of the Node ecosystem.

I see a lot of people suggesting that Signal was used primarily to help the administration evade accountability. That may be so, but I’d like to offer an additional reason: Signal is easy and convenient. I’m willing to wager that “high side” government computing systems aren’t even remotely so.

Interesting behind-the-scenes write-up by a Netlify engineer responsible for supporting Next.js deployment on their platform. (Let it be known that I was in the “never Next” club many many years ago, before it was cool.) eduardoboucas.com/posts/2025-0...

Lightweight node backends: CSRF? What’s that? Meh, someone probably wrote a middleware. Older dev forums: use the csurf middleware, it’s great! Csurf repo: abandoned with a known vulnerability. “Choose another package” says the README. Newer dev forums: discuss four different potential packages.

Since we had a bunch of extra almond flour, I tried making keto biscuits this morning. Pro tip: don’t.

If you create a brand new empty-from-template Next.js 15.2 or React Router 7 app, the optimized builds for the default home page (that does nothing) send 125KB and 111KB of JavaScript respectively. Is that good? Is it bad? I dunno, but my brand-new-from-templates sites always start with 0KB.

You know things have gone poorly when you have to do a deep read on module resolution in tsc. www.typescriptlang.org/docs/handboo...

Sigh for my Alma Mater.

Current status.

My kinda software shop: "We find hot new trends in the industry and then build the opposite of that." And they're doing a good job of setting some new trends of their own! bigsky.software

Only hours later and it sounds like Trump might back down, again, from his tariffs. It'll be fun to have huge, economy destroying tariffs randomly applied for only a handful of hours at a time... for the next four years of our lives!

I know a few really good people who worked at 18F in the past. Terrible.
