4 months ago, our announcement for our free, multi-node, petabyte-scale time-series database generated 200+ comments: https://news.ycombinator.com/item?id=23272992 Many commented on the Timescale License, our source-available license governing advanced features (eg multi-node). Most were positive, but some pointed out drawbacks (who says HN can't be productive!). That spurred an internal debate. Today we're happy to share an updated Timescale License with new rights, including the "right-to-repair" and "right-to-improve." And we’re doubling-down on our community, making all…

Hey HN -- thanks for showing interest in this. Happy to collaborate on this project. I'm hoping to get it stable soon so my own family can start using it. I've been working on this for about 10+ years, nights and weekends. It's been really slow going since I only have my own personal data to test it with. I just don't love that my data is primarily stored on someone else's computer up in the cloud. I want my own local copy at least. And while I can download exports from my various accounts, I don't want them to just gather dust and rot on my hard drive. So, Timelinize helps keep that data…

Hi HN! Today I'm launching OpenTimes, a free database of roughly 150 billion pre-computed, point-to-point travel times between United States Census geographies. In addition to letting you visualize travel isochrones on the homepage, OpenTimes also lets you download massive amounts of travel time data for free and with no limits. The primary goal here is to enable research and fill a gap I noticed in the open-source spatial ecosystem. Researchers (social scientists, economists, etc.) use large travel time matrices to quantify things like access to healthcare, but they often end up paying…

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…

Hi HN! We just released the public alpha version of Mathesar (https://mathesar.org/, code: https://github.com/centerofci/mathesar). Mathesar is an open source tool that provides a spreadsheet-like interface to a PostgreSQL database. I was originally inspired by wanting to build something like Dabble DB. I was in awe of their user experience for working with relational data. There’s plenty of “relational spreadsheet” software out there, but I haven’t been able to find anything with a comparable UX since Twitter shut Dabble DB down. We're a non-profit…
