Hydra 1.0 – open-source column-oriented Postgres
hi hn, hydra ceo here hydra is an open source, column-oriented postgres. you can set up remarkably fast aggregates on your project in minutes to query billions of rows instantly. postgres is great, but aggregates can take minutes to hours to return results on large data sets. long-running analytical queries hog database resources and degrade performance. use hydra to run much faster analytics on postgres without making code changes. data is automatically loaded into columnar format and compressed. connect to hydra with your preferred postgres client (psql, dbeaver, etc). following 4 months…
In plain words
Hydra is an open-source, column-oriented database that extends Postgres to accelerate analytical queries. It automatically converts and compresses data into columnar format, enabling fast aggregates on billion-row datasets without requiring code changes. Users connect via standard Postgres clients like psql or DBeaver. Hydra solves the problem of slow analytical queries that consume database resources, allowing complex analytics to run in minutes rather than hours while keeping operational performance intact.

Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
