I was looking at Hackney on hex.pm and, I noticed in the Versions tab that there were a lot of vulnerabilities… and they are super recent!

Takeaways so far:

If you ever used or built a chatbot, you know that LLMs love Markdown. But a lot of chat interfaces go beyond simple markdown and let models use rich UI elements. In this post I explain one way you can achieve this by teaching models to use cu

Around one tenth of CVEs published by the EEF CNA are caused by atom exhaustion, a denial-of-service vulnerability that is well understood, often preventable, and still showing up in production Erlang and Elixir applications.
