🗞️ For your weekend perusal, check out Unison community member @zetashift-01.bsky.social's latest blog post! Here, he's using Unison Cloud Daemons to write an uptime notifier! zetashift.unison-services.cloud/s/blog/posts...

computational.chat introduces a simple idea: computations that can pause for user input with rich UI controls. Unlike a typical chatbot, there's a real programming model here, and these conversational flows can include any mix of regular code, humans-in-the loop, and LLMs.

🌷The Dutch Unison Meetup is planning their next in-person meeting for late March! Come say hi in our Discord if you're in the neighborhood! unison-lang.org/discord

📝 This community write-up on Unison asks: what if service boundaries didn’t mean serialization, versioning pain, or extra operational complexity? Check it out here: medium.com/@thomas_alex... Or here: github.com/ThomasAlexan...

🎥 New conference recording from the Unison community! A deep dive into content-addressed code and how it changes refactoring, dependency management, and remote code execution. 🌟 Dejan's keynote is one to watch! www.youtube.com/watch?v=mQHo...

🫣 Ever open social media to post one thing… and resurface 20 minutes later? Well, here's @impurepics.bsky.social wiring up a Unison-powered CLI solution for that. They walk through the code, the Unison workflow, and how it all fits together. 👑 Thanks @impurepics.bsky.social, we're huge fans!

Finally got around watching it in full. New threads ability of @unison-lang.org youtu.be/xU_MRNNo4kg?...

We have a consulting group, now open to work in a variety of languages, including Scala, Haskell, Rust, Elm, and of course Unison. More details here: www.unison-lang.org/blog/consult... Please boost to help get the word out. And we'd love to hear from you if you're interested in working with us!

🧵🪡 Our latest release of the standard lib includes a new `Threads` ability for structured concurrency. Why is it an improvement over our existing primitives? Here's a video with some comparisons. youtu.be/xU_MRNNo4kg

📰 New Base library version is out! This one has some big features: * New `Threads` ability for structured concurrency * Adds a `Ptr` type so Unison can exchange pointers with C * Load a dynamic foreign library by name share.unison-lang.org/@unison/base...

🌟 Check out the suite of libraries that @kaushikc.org has been steadily developing: html-parsing, at-proto, and more!

🎥 The Unison 1.1.0 release has quite a few features improving the UCM workflow. Here's a highlights reel: youtu.be/8aMggn5Cm00

📰 UCM 1.1.0 is out! * `dependents` can search by variant, not just type or ability name * New built-ins for Argon2id hashing * VS Code actions: Edit Definition & Open on Share * MCP tool: `share-project-info` * Faster bytes ops & improved run command

I've used @haskell.org, Lean 4 and @unison-lang.org for a while. I'm impressed by improvements, but many languages have good FP features now. Wrote blog post Competitive Pure Functional Languages. blog.samibadawi.com/2026/01/comp... Looking for niches where pure FP is better than OOP FP language

Unison's got a C FFI! 🎉 If you were waiting for a reason to try Unison, now's a good a time as any :)

🔌 We're adding C FFI bindings! This opens the door to a huge ecosystem of native libraries. Go wrap your favorite C APIs! share.unison-lang.org/@unison/base...

⏳Time is precious. Stop typing out fully qualified argument names in the UCM! youtu.be/_pcDWMj9JWg

⌨️ A fun Unison library drop for your Monday! Dream up some terminal UI apps! share.unison-lang.org/@stew/tooey

👀 We don't have a REPL in Unison, so what do we use instead? Watch expressions! youtu.be/xfKO_tGpBxM?...

📰 Unison 1.0.2 is out! - `diff.update` lets you preview a change before committing an update - MCP upgrades: agents can rename, move, and delete definitions & namespaces - Fixed `text.find` for numeric literals - Parsing fix for multi-line matches

What might a Terraform library look like in Unison, given the programming model that Unison Cloud supports? 🎙️Tune in to our interview with library author and Unison teammate, Stew, to see what he's tinkering on!

🎉 Yes! It's a lovely time to get reacquainted with Unison!

🔠 You know what would be awesome? If the Unison programming language had a little font icon. Give this FontAwesome request a quick upvote if you agree!

@unison-lang.org v 1.0 passes my language readiness criteria * Good language server support * Trivial to make a word frequency program with tests It's mind blowing 🤯 to program with code fragments, instead of projects of files. Very composable. Promising, but hard to imagine its effect on DevOps

🌟 #AdventOfCode is in full swing in Unison! Our community has made full use of Unison's computable doc format, writing up their solutions and helpful explainers! Here's one from the Discord about Day 3! Join us! 💌

📰 Check out who's in the latest Future of Coding Weekly newsletter!

🌟 It's time for #AdventOfCode! That means it's a great month to pick up a new programming language! Try it in Unison this year! 🎁

I've been watching Unison's development for several years. I was hooked the moment I first saw the slide "A Unison codebase is a database." Since then, an entire ecosystem has grown, including UCM Desktop, Unison Share, Cloud... And now, 1.0 is out! 🎉

HELL YEAH!!!! I cannot describe how happy this makes me, ever since hearing Runár give an early description of the idea... The subsequent conversation had me hooked immediately.

Want to try a radically innovative programming language? Unison is ready! Unison is approachable, user-friendly, and has a great community of friendly folks :) On top of that it has mind-bending features like serializable function closures and built-in distributed programming tools!

🎉 Unison 1.0 has landed! After years of engineering, design, and community collaboration, we’re excited to announce this milestone! Spread the word!

In "a new programming paradigm" Dejan Milicic goes into why @unison-lang.org is so unique and useful: docs.google.com/presentation...

This release will serve as a Unison 1.0 release candidate, setting the stage for a 1.0 version once we confirm there are no major issues.

Yesterday, at @lambdanantes.bsky.social, @etorreborre.blog made me want to try @unison-lang.org (for a toy project) !

📰 Unison 0.5.50 is out * New `branch.diff` command (with diff-tool support) * Support for adding comments to branch history * MCP agents can `test`, `update`, and `run` code * Smarter `run` command behavior Check out the full release notes:

👏 Check it out! A great write-up from Eric! 💻

A Unison terminology reminder, for the working dev: ↖️ Dependents: what 𝘶𝘴𝘦𝘴 a given term (where is this thing even called?) ↘️ Dependencies: what is this term 𝘮𝘢𝘥𝘦 𝘧𝘳𝘰𝘮 (how does this code even work?) Fortunately, Unison Share exposes both in our code browsing UI!

🚀 New deep dive: Distributed System Engineering in Unison In our latest blog post, take a look at the design of the Volturno library: a distributed stream processing engine built atop Unison Cloud. www.unison-lang.org/blog/volturn...

🇳🇱 Welkom! The Unison Dutch meetup is tomorrow! If you're in the Netherlands, rsvp and say hello to the friendly Unison crew there!🌷

🔎 As you're writing applications in Unison, you might need to search for a substring (where is this error coming from!?) or numeric literal (who put this magic number in my codebase!?) Here's a quick workflow video for that using the text.find command:

🤯 Unison in the browser!? Dan Freeman's new library, Proscenium, runs Unison code in WebAssembly. Its companion library, @dfreeman/playbill, contains a walk-through of various features and live examples on Unison Cloud! Play a game in your browser entirely in Unison; better yet, write your own!

📮 New library to start your week: `lib.install` the Telegram library or check it out on Unison Share! The library features a quickstart to get you up and running using the Telegram API, and also details some of its design decisions, for the curious dev.

📽️ Here's a quick video for anyone just getting started with Unison. The gist of it: install the UCM, create a scratch file in the right place, and have fun programming!

💖 We love seeing what y'all are building! Keep it up folks!
