Show HN: Booklet – Async forums as an alternative to chat
19 by philip1209 | 7 comments on Hacker News.
I built Booklet to solve the problem of too many chat messages at work. Booklet updates classic internet forums and email groups to have a modern UI and high polish. It organizes communications into threads, and summarizes activities into a neat email newsletter - so members can stay updated without having to stay logged in. The async format promotes deeper discussions, while also increasing engagement by making conversations easy to follow. My goal is to make communications more asynchronous - so that I can get back to work, instead of slacking all day. Most early communities have been hobby groups, but my goal is to mature Booklet into a tool that sits alongside Slack in companies. Try it out, and let me know what you think!

New top story on Hacker News: Show HN: Hydra - Open-Source Columnar Postgres

Show HN: Hydra - Open-Source Columnar Postgres
41 by coatue | 5 comments on Hacker News.
hi hn, hydra ceo here hydra is an open-source extension that adds columnar tables to Postgres for efficient analytical reporting. With Hydra, you can analyze billions of rows instantly without changing code. demo video (5 min): https://youtu.be/1yzxgb0Oyrw github repo: https://ift.tt/gBToJaq For 1.0 GA release, aggregate queries are over *60% faster* than Hydra beta due to aggregate vectorization. Spatial indexes (gin, gist, spgist, and rum indexes) and pg_hint_plan are now enabled for performance optimization. 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 changing code. for testing, try the hydra free tier to create a column postgres instance on the cloud. https://ift.tt/Ysgx5jL
