Seems like a good day to start on the #current24 slides.

First look at @ElectricClojure v3's improved network transfer semantics, that let the programmer express with precision the exact network topology they want with intuitive and obvious code! Blog post: hyperfiddle-docs.notion.site/Electric-Cloju…

Rama has ~3,700 tests and ~22,000 assertions, about one test per 53 lines of source and one assertion per 9 lines of source. We have 18% more test code than source code. This doesn't include our automated chaos testing against real clusters, a separate 20,000 LOC project.

Quick @ElectricClojure progress update! Also, officially announcing Electric v3, coming very soon! hyperfiddle-docs.notion.site/Electric-progr…

Maybe instead of #NoEstimates, it should be #WhyBother. We all know they don’t work. Estimates are the worst sort of productivity theater, given that nobody believes that they’re even close to accurate.

@driscollis I just found out you can run a repl as an interactive window in VSCode rather than the terminal... Mind blown 🤯🤯🤯

When somebody not using a Lisp Explains to me how flexible their favorite programming language is And I don't have enough time to explain Lisp macros to them

Thanks to all my readers, my book is back at #2 on the functional programming list on Amazon. But we have to beat the Python book, out of principle! ericnormand.me/gs

I heavily prioritize immutability and referential transparency when programming because of the extreme benefits they provide, so it's interesting when mutability is exactly what's needed for a problem.

The 2024 StackOverflow survey is out, and for the 8th year in a row, Clojure has ranked near the podium in the Top Paying Technologies category—often occupying rank 1. I don't talk much about why I choose to use a weird Lisp—mostly because nobody cares—but the results speak for themselves. If you can hold your nose long enough to learn something very different, you'll find yourself in a high-productivity environment that features: 🔥 Hot code reloading 🦆 Dynamic typing ♻️ Best-in-class garbage collection 📂 Highly performant immutable data structures 📚 Access to the entire JVM's ecosystem of libraries 🧩 Cross-platform compilation to JavaScript 🧠 An unbelievably smart and humble community Sure, you'll pay a high mental price to learn the language, but as a reward, employers will pay a high price for you.

Tesserae, a Clojure spreadsheet written in Electric Clojure by @dennnis – ClojureNYC video now online! "I’ve tried writing a Clojure based spreadsheet before and failed. A naive implementation was never performant enough and I simply didn’t have time to pour my lifeblood into architecting a side project while running a company and having a life and doing -important research- reading Twitter. All of this changed with Hyperfiddle Electric (think: cross environment Clojure code composition). Within two weeks part time I had written Tesserae, a sandboxed Clojure spreadsheet with cell reactivity, scheduled code execution, hiccup, vega rendering and more — and all of that in under 2000 LoC 🤯 of honestly fairly naive but, thanks to Electric's performant code. Since then, Tesserae has been actively used at Lumber as a dashboard, budget notification service and invoice generator. In this talk we’ll dive into Tesserae’s capabilities, code and Hyperfiddle Electric." youtube.com/watch?v=nEt06L…

For all the talk of the benefits of diversity, nobody seems to question the wisdom of running civilization on a single version of a single operating system from a single vendor. #BSOD

Do you agree? 🤔

Do you work in financial services? Do you like open source software? Then you should definitely take a look at the work happening across @FINOSFoundation ! Most notably, we will be collaborating over the coming weeks to integrate XTDB into some trading system demo scenarios 🧑‍🔧

"Flowmaps" #Clojure Flow Based Programming micro-framework. Link fns together & core.async does the heavy lifting. Conditionals, loops, multi-inputs, in-line visualizations, etc. Debug, visualize channels & values with the optional web ui. Should be on GH & Clojars by monday.

🤯 Holy cow. I upgraded the custom ShadowTraffic GPT with a better knowledge base, and it's 🎯 accurate. I asked it to generate 3 Kafka topics—customers, orders, and support tickets, with relational data between them—and it got it 100% right on the first attempt. Zero syntax or semantic errors. Even asked it to connect it with Confluent Cloud, and it got the configs dead on.

I read these books 📚 Some of them are worth reading, others worth scanning, and some it would be a blog post! #ama #programming #MyElixirStatus #ddd #eventdriven #systemdesign #softwarearchitecture
