Bluesky Map Interactive map of 3.4 million Bluesky users, visualised by their follower pattern.

I made a map of 3.4 million Bluesky users - see if you can find yourself!

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

⚠️ Just a few tickets left! Learn from Erlang's co-creator, Elixir Core Team & BEAM legends. 5 masterclasses included. Last chance: codebeamvancouver.com#tickets

We're launching our new Elixir book! 🎉

Programming Nerves: from web developer to hardware maker.

If you've ever been curious about hardware but felt intimidated, this is for you.

Beta available now (38% off), or download free chapters to get started.

Saturday mornings are set aside for writing "Financial Analytics Using Elixir". And I must say....I'm really pleased with how the analysis framework is coming together 😍. @livebook.dev and its supporting tooling is such a nice fit for this!

So exciting!!! 🙀🙀🙀

Introducing swift-erlang-actor-system I'm excited to share a new actor system we've been building for Swift's distributed actors: swift-erlang-actor-system. This actor system enables Swift programs to join a distributed Erlang cluster. ...

Awesome, another node comes alive! #ElixirLang

Not using AI for programming reminds me of when we had to code C on paper in some undergrad programming courses. Yeah, you can do it, but why?

I feel 2025 is the tipping point for AI use for serious software development, not just vibe coding. Here's my take on it: senkorasic.com/articles/ai-...

My copy of "The BEAM Book" arrived today, and it's wonderfully colourful inside and out!

Cursor YOLO deleted everything in my computer Hi everyone - as a previous context I’m an AI Program Manager at J&J and have been using Cursor for personal projects since March. Yesterday I was migrating some of my back-end configuration from Exp...

To be fair, when everything is deleted on your disk, it means that there are no problems on your computer, so there's that 🤷

Happy to see The BEAM Book finally out in paperback! Need to grab a copy soon!

GitHub MCP suffers from the lethal trifecta for prompt injection: access to private data, exposure to malicious instructions + the ability to exfiltrate information

Be really careful with this stuff: attackers can trick your "agent" into stealing your private data simonwillison.net/2025/May/26/...

It does for sure!

I guess it does not hurt to use both as they serve different purposes @david.bernheisel.com

APQs:
* Reduces network and server overhead by sending only a short hash of the query to the server. Server skips parsing and validation if the query is already stored. If query variables change, the same persisted query can be reused with different variables.

Thank you!

Regarding client caching vs APQ -

Client caching avoids redundant network requests by storing query results. Still sends the full query if not cached. If query variables change, it triggers a new request. Parsing and validation happen normally on the server.

Just had my latest article published on elixirmerge.com! 🚀

I walk through implementing Automated Persisted Queries (APQs) in Elixir using Absinthe.
If you're working with GraphQL in Elixir, this one's for you!

Big thanks to the Elixir Merge team for the feature 🙌
#ElixirLang #Absinthe #GraphQL

I think I’m most proud of our decision to built in extensibility as a core feature of Absinthe via the pipeline; it’s always a joy seeing how creatively others use it.

#ElixirLang

Automated Persisted GraphQL Queries with Absinthe and Elixir Long ago I wrote an article titled — “An Opinionated Way of Organizing GraphQL APIs using Absinthe and Phoenix” on architecting GraphQL…

AI and Programming: The Beginning of a New Era

🧠 Weekend fun: vibe coding with
✨ Tidewave (tidewave.ai) + Claude Desktop (claude.ai/download) + Elixir/Phoenix Framework.

Looking forward to seeing where Tidewave goes!

#ElixirLang

Introducing Tidewave: tidewave.ai

While working on our web apps, we run code, query the database, read logs, search docs… but our AI tools are limited to reading code.

Tidewave closes this gap by introducing Runtime Intelligence, for Phoenix and Rails. More coming soon, check out the website!

How to Async Tests in Elixir It can be hard to keep tests asynchronous as Elixir applications grow in size and complexity. Let's see why, and explore fixes.

I wrote about something very close to my heart: how to make ALL the tests async in @elixir-lang.org.

Enjoy! 🏎️

The Best Programmers I Know | Matthias Endler I have met a lot of developers in my life. Late…

"Clever engineers write clever code. Exceptional engineers write simple code."

100% agree with this. There are rare exceptions that call for clever or innovative, but most of the time you think you're being clever you're just leaving a trap for a future you.
