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!

This one had a lengthier rc period.

It brings type system improvements and compile time improvements in large projects among other things 🚀

So exciting!!! 🙀🙀🙀
This changes how you’ll demo, teach, and explore Elixir.

New Popcorn release coming tomorrow – here's a sneak peek of what's to come 🍿

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-...

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

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/...

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.
May 21, 2025 at 2:30 PM
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 🙌

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.

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!

"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.
