Show HN: Hydra - Open-Source Columnar Postgres
40 by coatue | 4 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/L2dYhn0 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/hmGkbIR

Show HN: Loopy – share and find and music you love
8 by kylel95 | 0 comments on Hacker News.
Hi, I created loopy, a website to share and discover music you love. A former coworker answered an ice breaker question saying his superpower would be to know every language fluently since he travels a lot. Mine would be to hear every song I would fall in love with. I realized that I will die without hearing every song that I will fall in love with. So many of my all-time favorite songs I randomly have heard at a club, coffee shop, traveling, walking by a store, etc. There is a high chance that I would have never heard those songs. Loopy aims to fix this. You can post your all-time favorite songs. If someone else love this song, there is a chance you will too :). Here is my profile: https://loopy.fm/kyle Happy listening :) - Kyle

Show HN: Erlmacs – a script to update your .emacs file for Erlang development
5 by dlachausse | 0 comments on Hacker News.
erlmacs automatically configures and updates your .emacs file with support for the emacs mode that is included with Erlang/OTP. It frees you from having to locate the installation directory of Erlang/OTP and its bundled emacs mode. It is an escript that only depends upon Erlang/OTP and Emacs. Note: There is not much in the way of error checking at this moment, but it does make a backup of your .emacs files before any destructive operations.

Show HN: Modular Diffusion – A modular Python library for diffusion models
6 by secularchapel | 0 comments on Hacker News.
Hello everyone! I've been working on this project for a few months as part of my thesis in Machine Learning. It's meant to be a library that provides an easy-to-use but flexible API to design and train Diffusion Models. I decided to make it because I wanted to quickly prototype a Diffusion Model but there were no good tools to do it with. I think it really can help people prototype their own Diffusion Models a lot faster and only in a few lines of code. The base idea is to have a Model class that takes different modules corresponding to the different aspects of the Diffusion Model process (noise schedule, noise type, denoising network, loss function, guidance, etc.) and allow the user to mix and match different modules to achieve different results. The library ships with a bunch of prebuilt modules and the plan is to add many more. I also made it super easy to implement your own modules, you just need to extend from one of the base classes available. Contrary to HuggingFace Diffusers, this library is focused on designing and training your own Diffusion Models rather than finetuning pretrained ones (although this is possible). I would really appreciate your feedback.

Ask HN: What is your policy regarding smartphones for your children?
9 by eimrine | 9 comments on Hacker News.
Recently, there are more and more studies that smartphones harm learning and not a single study with the opposite results. However, very few parents have the guts not to buy a smartphone for their child. At what age do children in the HN crowd begin to have censored access to proprietary software (personal supervision) and uncensored (smartphone with or without parental controls)? Are there families where children have access to computers with only FOSS before they have access to proprietary software?
