Touched down in Charlotte for #ClojureConj

I need a progress bar for something with a wildly varying estimated time to completion — but I still want to show constant progress. So here’s the 💡: a dot moving at constant speed along a space-filling curve (Hilbert?) and dynamically adjusting the curve’s resolution as the ETC changes. Thoughts?

A friend gently reminded me on my birthday: “There’s always a number base where you’re in your 20s — and the number of such bases keeps increasing.” I’m more in my 20s than ever!

I finally found a good name for the infamous macro previously known as <<- or else->>: 🥁 🥁 🥁 warp->> (pronounced warp last) #clojure

Kudos to wevre for shipping transit-dart & transit-cljd (it passes all tests). Thanks a lot 🤘 github.com/wevre/transi... github.com/wevre/transi...

In The Economist:

Devastated to report I read the docs and learned everything I needed to

It’s a special kind of sadness seeing the entire genre of art made with computers that I have been pursuing since the 70s ruined by AI slop. I have never been less motivated to share new work in my life. 😿

There is no longer the satisfaction that your consumer is a human (who might write a comment, say thanks, post on HN, etc.); nor the cred that comes from people reading and remembering the author, posting on HN, etc. That is, it totally destroys the incentive structure.

I’m on the lookout for new dev gigs. #clojure

Okay. A lot of « optimizations » are about tricking our brains into thinking they do something good for us. Are there groups looking into designing around our flawed brains rather than against them?

Almost all chat software automatically scroll to the end of the conversation. (Even terms and repls.) But not chat AI UIs. Because you are expected to read the output. Our chat UIs makes it too easy to skip and ignore.

“I recall the instant I realized that a large part of my life was going to be spent finding mistakes in my own programs.” #MauriceWilkes, 1949

Our new paper, “Datalog with First-Class Facts,” will appear at VLDB ‘25. We are very excited about this work, which harmonizes concepts from functional programming and databases.

Not only that #Clojure have been supporting high performance computing on Apple M CPU since Neanderthal 0.53.0, but the even more optimized operations through Apple Accelerate is coming soon! Check it out now at github.com/uncomplicate/neanderthal #MachineLearning #Python #NVIDIA #Swift

🖥️ Jeffy, Lead Engineer at Holiday Pirates, walks us through how he introduced Clojure at scale – starting from zero experience to powering 95% of backend development. 🧰 For CTOs and tech leads, it’s a goldmine of insight: www.freshcodeit.com/podcast/the-...

ClojureDart stack traces are now sourcemapped and highlight the failing expression.

Me: Hi AI. Add this button for me AI: Yes, I added the button for you. I also deleted a large chunk of your business logic. Me: Why? AI: I don't know why. Deal with it

The most distressing part of the decline of reading is that reading's core purpose is to not only present facts, perspectives, and information, but to expose us to the mechanisms of thought itself.

This bug was weird. All of a sudden code stops compiling. The only change? The reader now adds end source location metadata. If I add only end column or end line it’s ok. But not both. The failing form? (ns foo (:require [bar :refer [x y]])

Lego 7777 train book is still strong and makes my smallest son daydream.

(Please re-skeet for visibility) Did you use HyperCard back in the day? What was your experience with it? What did you make? How did it change the way you think about yourself?

ClojureDart has a new join-with function which has accelerated datastructure support. What is it useful for? Some examples 👇🧵

One more week to propose a talk for the ⭐SciNoj Light⭐ #Clojure conference. scicloj.github.io/docs/communi... If anybody is considering a talk, now is the time to talk with us, and we will help you brainstorm your draft proposal.

Structurally accelerated merge gives a nice boost (7x) in worst case making CLJD faster than CLJ even on bad cases. See updated gist gist.github.com/cgrand/6303e...

ClojureDart merging maps 1000x faster than Clojure? 😇 gist.github.com/cgrand/6303e...

There's clojurescript in react native and also clojure dart ;)

ClojureDart repl is coming for real!

Oddly satisfying. Almost hypnotic.

I had numerical stability issues in an app. Naively switched to ratios. Now the app spend 33% of its time computing GCDs 🥸

Talk #2: "DB usability: as if" by Jonathan Edwards (jonathoda.bsky.social)

The first few HYTRADBOI 2025 talks are ready! I'm so excited to be finally able to tell people about them! Talk #1: A YJIT interview with Maxime Chevalier-Boisvert

Wow 🤩 Rich Hickey landed a new namespace: clojure.core.async.flow github.com/clojure/core...

Is the space of client/consumer apps running on user-provided commoditized object storage (S3-compatible) being explored?

Brian Eno on AI is spot on

#Clojure folks, do you also know #CommonLisp, or other lisps? What’s your journey to Clojure been like?

I used ChatGPT to generate a series of formally correct but factually inaccurate statements about an assigned reading. The students had to explain how they were wrong. This is because I think AI is better at faking expertise than constructing solid arguments.

Pencil and paper are back! For the analog games readings, I had students write a short response on paper at the start of class. They were given two prompts, and surprisingly, no one complained. I was shocked by how good their calligraphy is!

4yo: Dad, what’s 3 and 3? Me: 6 Him, counting on his fingers: yeah, you’re right!

You’re not going to find the perfect candidate when hiring, and it’s pointless trying. It takes at least a year to get a fresh dev up to speed The best you can do is find someone who’s eager to learn and has built software by themselves that they can demonstrate and is generally good to talk to

Some non obvious removal of gensyms in core macros to make cljojuredart output more stable github.com/Tensegritics...

Are there lisps (or any language) where macro expansion can happen in post-order? Well to be honest the only thing I would be interested at the moment is post-order providing all used symbols. So just a 2-phase macro, preorder as usual and then postorder to tune the expansion.

Pretending persistent data structures solve undo/redo is about the same kind of fallacy as pretending CRDT/OT/whatever solve sync.

Call for live coders! We're looking for 100+ live coders to each contribute a live 15 minute performance to the online TOPLAP solstice stream, taking place around 21st December 2024. Info here: blog.toplap.org/2024/12/09/s... Please share this call with live coding communities you are part of <3

New article: beyond swap! The transactor pattern buttondown.com/tensegritics... #clojure

My favourite thing about Clojure is that there are no "migration guides".. no need to write, read, or use them. You just update your dependencies if and when you want to, then carry on. This is how it should be.

🎁 Day 6️⃣ of our Content Advent Calendar 🗓️🎄 While static typing is a #programming staple, dynamic typing is gaining appeal for quicker iteration, flexibility, and adaptability. We weigh its merits against static typing's reliability. Listen to the full podcast here ➡️ www.juxt.pro/blog/dynamic...
