T-SQL Online

What it does

Most online SQL playgrounds run MySQL or SQLite — not real SQL Server. T-SQL Online is a browser sandbox built for Transact-SQL: write queries, create tables, run JOINs, constraints, stored procedures and triggers, and see results instantly. No install, no setup. Features a live interactive ER diagram and collaborative rooms (beta). Perfect for students, devs and teachers. Free, with premium plans for more databases and storage.

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
