  • Translate between dialects and share SQL queries on the browser2025 · sqlscope.netlify.app · ▲19

    Last year, I wanted to learn a bit about how easy it would be to deploy a python app via web assembly to the browser and decided to make a wrapper around the amazing sqlglot by Toby Mao and the rest of the team. The tool lets you paste in Sql queries and translate them between the available sql dialects in sqlglot. It also gives you parse diagnostics and the ability to easily share queries via storing all the state in the url. The stack that was used is typescript for the UI and pyodide to integrate with Sqlglot, which does the heavy lifting. It's more of a toy app but I've found some use…

  • DBLift – database migration management for Python teamsAug 2026 · dblift.com · ▲6

    I’ve been working for a while on DBLift, an open-source database migration toolkit for Python teams. DBLift follows the same model flyway does with the same main commands and the same history table structure making it easy to switch from one to the other with the import_flyway command. By default DBLift is out of order meaning that any unapplied migration is eligible to be applied contrary to flyway which refuse to apply any migration with a lower version until you force it. You can still apply the original flyway model you can still opt-in with the —strict flag.…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
