hackney 4.3.0 is out: HTTPS connection pooling, TLS 1.3 session resumption, smarter SNI, and QUIC/WebTransport bumps for the Erlang HTTP client. github.com/benoitc/hackney/r…

If we want to build software factories (still an if for me), how can we build good ones? I think that’s the biggest gap in how people use LLMs right now. And I don’t know about you, but I think it all comes down to verification. 👇 germanvelasco.com/blog/draw-…

🚨 Big news! We’ve officially joined the CVE® Program as an authorized CVE Numbering Authority (CNA)! This means we can now assign CVE IDs to publicly disclosed cybersecurity vulnerabilities in our defined scope, helping improve security 🔐 and transparency 🔎 in the broader open-source community. 👉 Learn more: erlef.org/blog/security/eef-…

I started a Hologram newsletter last year, sent two issues to a few hundred subscribers, and then went quiet for nine months. (Hologram is the Elixir web framework I build, in case we haven't met.) The honest reason is I made each issue too big, these 3,000-word write-ups. And back then I wasn't working on Hologram full-time, so writing one every month was the first thing to slip. I don't want to leave people hanging like that again. This time I'm doing it differently. Hologram is moving to a regular release cycle, a minor release every 4 weeks, and the newsletter goes out in week 3 of each one. Shorter issues, tied to the releases, so this time it should actually stick. And there's plenty to write about. People are building libraries and packages on top of it, and the demos that keep showing up still surprise me. The newsletter pulls that together along with the releases and the threads worth reading on the Forum and Discord, so you're not chasing it across five different places. If you read the first two issues, I'd like to hear what you liked. And if you didn't, what would make a Hologram newsletter worth opening? I want to get this version right. The first issue back goes out next week. Subscribe here: hologram.page/newsletter

Hey Elixir friends, the screenshot below is all the realtime code you have to write for a chat room in Hologram (new in v0.9). 17 lines of code. I'd love to take credit for all that simplicity :) But honestly it's an iceberg situation - what you see is the tip, and most of what makes it work sits below the waterline. Clustering, message routing between nodes, process supervision - none of that is Hologram code. It ships with the BEAM, the Erlang VM that's been running telecom switches for decades and powers WhatsApp today. The cluster can grow or shrink and broadcasts keep finding every client connected to it - I didn't write a single line of that routing. What I did build is the layer in between, the part that turns all that raw capability into a declarative API. It sounds like a thin wrapper but it really isn't - there are tombstones, client-side receipts, and a bunch of other machinery underneath whose whole job is keeping those one-liners correct without the developer ever noticing. That's the quiet superpower of building a web framework on Elixir - the BEAM takes care of the distributed systems part, so all my time went into the layer developers actually touch. What's the biggest thing the BEAM has saved you from building?

Hey Elixir friends! :) Hologram v0.9 is out - now with Realtime! ⚡ Your Elixir server can push updates straight to the browser - no polling, no JavaScript. Broadcast an action, and it runs on every subscribed client, in pure Elixir. Plus the with special form, AI assistant support, and a new mix holo task. hologram.page/blog/hologram-…

As soon as I recognize vibed text I lose interest. The reason is that I have to wonder for every sentence if it is your thought, or an LLM-produced filler. If you give me three incoherent short original sentences, at least I have something to work with. I know these are your thoughts, and so I can try to understand them, maybe ask some follow-up questions. If you turn it into a polished vibed text, the only thing I can do is skip it :/

Open-sourcing Folio — a by-product of one of my commercial projects. Print-quality PDF/SVG/PNG from Elixir data, powered by Typst via Rustler NIF. Documents are just Elixir values: for-comprehensions become table rows, math renders natively, layouts compose. No templates, no external processes. github.com/dannote/folio

🔒 The EEF, in collaboration with Alpha Omega, has completed the first comprehensive third-party security audit of the @hexpm. This work is part of the ongoing efforts to strengthen security across the BEAM ecosystem under the Ægis initiative. erlef.org/blog/eef/hex-secur…

It's here! gleam_stdlib v1 released!

Securing @hexpm 🔐 Over the past months, a dedicated team conducted the first comprehensive third-party security audit of Hex.pm and its surrounding ecosystem. This work was made possible by @AlphaOmegaOSS, an initiative under OpenSSF that funds security improvements for critical open source projects, and was carried out as part of the Erlang Ecosystem Foundation’s Ægis initiative. 👉 hex.pm/blog/security-audit

When I see a guy branch that starts with someone’s name or initials or self identifying piece it makes me sad. I want the project to be everyone’s work. Team ownership over self. Team based mentality starts with small thoughts and they lead to bigger changes in behavior.
