Show HN: Mathesar – open-source collaborative UI for Postgres databases Hi HN! We just released the public alpha version of Mathesar ( https://mathesar.org/ , code: https://ift.tt/l5SbsAI ). 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 project. The core team is based out of a US 501(c)(3). Features: * Built on Postgres : Connect to an existing Postgres database or set one up from scratch. * Utilizes Postgres Features : Mathesar’s UI uses Postgres features. e.g. "Links" in the UI are foreign keys in the database. * Set up Data Models : Easily create and update Postgres schemas and tables. * Data Entry : Use our spreadsheet-like interface to view, create, update, and delete table records. * Data Explorer : Use our Data Explorer to build queries without knowing anything about SQL or joins. * Schema Migrations : Transfer columns between tables in two clicks in the UI. * Custom Data Types :: Custom data types for emails and URLs (more coming soon), validated at the database level.

Show HN: Launch VM workloads securely and instantaneously, without VMs Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack channel. Thanks! April 29, 2021 at 07:50AM
