Metals V2 open-sourced for big Scala & Java codebases, this is huge: kudos @databricks! databricks.com/blog/open-sou…

Mojo 🔥 1.0 is here. Since we open-sourced the standard library, nearly 200 contributors have landed more than 1+ pull requests, changing 200k+ lines of code, and more than 1k+ others have filed issues that shaped the language. To every developer who filed an issue, opened a pull request, wrote a language proposal, or built a package: thank you for being the architects of this language alongside us.

Introducing celld: a self-hosted, distributed Durable Objects and Workers implementation - celld = V8 + S3 + SQLite + LTX+ Tokio - programmed with exactly the Cloudflare Workers/DO JavaScript APIs and config - order of magnitude cheaper at scale - writes are durable before they're acknowledged, RPO=0 - only depends on an S3 compatible bucket - no other infrastructure - ~4 MB memory per cell instance overhead - hibernated cells cost ~nothing, just their S3 storage - open source, Apache 2 licensed

Today is the day: #Hardwood reaches 1.0 🚀! A from-scratch #Parquet library for the JVM, reading (and soon writing) Apache Parquet fast: multi-threaded at its core, with no mandatory dependencies. Java 21+, Apache 2.0, production-ready. Happy Parquet parsing!

Hey @EpicGames! Small quick-win UX suggestion. On DLC store pages, there's no way to quickly go to the base game and requires searching (eek!). So you can either add a link to the base game page and/or provide an option to get both the DLC and the base game in one transaction.

Does anyone want a tool to export Confluence Whiteboards to SVG and up to a degree to jsoncanvas?

Mojo 🔥 1.0 is in beta! Beta 1 marks the first step towards finalizing 1.0 later this year, which will bring a new level of language stability. The beta lands safe closures with a new capturing syntax, conditional trait conformance, and major variadic improvements. Plus, Mojo has its own home at mojolang.org.

Are there any free and slick alternatives to PopSQL for a nice in-cluster, hosted PG access shared experience that's not DBeaver?

Introducing Tolaria! 💧 Today I am releasing a macOS desktop app for managing markdown knowledge bases, and helping both AI and humans operate them. It’s free and open source, and always will be. I have been working on it for three months, and I now use it to run my life and work. I personally have a massive workspace of 10,000 notes — the result of 6 years of Refactoring — which I now operate on Tolaria. Tolaria is the main collaboration surface with my AI agents: they create new notes there, connect them to what exists, and edit existing ones. Everything is easy to understand for them, because it’s just markdown files. In a way, it’s my implementation of @karpathy's LLM wiki. Tolaria is also the biggest experiment I have ever run about writing software with AI: • 2000 commits • 100K+ lines of code • 3000+ tests / 85% coverage • 9.9/10 code health • 70+ architecture decision records I am releasing it open source also to use it as a living artifact of how I do AI coding, so you can inspect at any time things like how I write docs, what's in my AGENTS file, what hooks do I run, and so on. You can find it below: • Newsletter announcement: refactoring.fm/p/introducing… • Website: tolaria.md/ • Github repo: github.com/refactoringhq/tol… Let me know your thoughts!

⚡️ Zig 0.16 is out. And the new I/O model is a huge shift. • Swap implementations (threaded, evented, etc.) • Write code that looks blocking but runs async • Composable like allocators ziglang.org/download/0.16.0/… #zig #ziglang
