thisismahmoud_on AI wants to nuke your database. Guardrails fix that

We share more details about what happened. Tokens on Railway can actually be scoped pretty narrowly, all the way down to a single environment. In the post that went viral the token was account-scoped, which was way more access than the task needed. We'll improve the UX so it's obvious which token to create.

Also, volume deletions now schedule with a 48-hour grace period, in both the dashboard and the API. You can always undo. Overall we want to have more guardrails set up in place since more and more people will interact with Railway via agents

Learn about the latest new features introduced in Postgres 16 for working with JSON data

thisismahmoud_on [dead]

A few weeks back, we released pg_embedding[1], a new extension for Postgres and LangChain which introduced Hierarchical Navigable Small Worlds (HNSW) indexes for vector similarity search. This new indexing method resulted in 20x faster queries at a 99% accuracy compared to traditional IVFFlat indexing[2].

Today, we released a new version which includes the following improvements:

1. The HNSW index is now constructed on disk instead of in memory

2. The extension now supports Cosine, Manhattan, and Euclidean distances
