1. John Deere owners will get the right to repair equipment under FTC settlement
⭐ 886 💬 173 👤 djoldman 🔗 Discuss on HN
Under a settlement with the FTC, John Deere will grant owners the legal right to repair their agricultural equipment. The agreement covers diagnostics, spare parts, and repair manuals — areas that have historically been restricted by the company, limiting farmers’ ability to service their own machinery.
2. Spider venom kills varroa mites without harming honeybees
⭐ 145 💬 64 👤 Jedd 🔗 Discuss on HN
Researchers found that specific spider venom components effectively kill varroa destructor mites — a devastating pest for honeybee colonies — without harming the bees themselves. The discovery offers a potential new class of targeted treatments for colony collapse issues, avoiding the resistance problems of chemical miticides.
3. Meta reuses old RAM in new servers with custom bridge chip
⭐ 55 💬 11 👤 ihsw 🔗 Discuss on HN
Meta has developed a custom bridge chip that allows older DDR4 memory modules to be reused in new servers running DDR5. This approach extends the lifecycle of existing hardware inventory while reducing e-waste and procurement costs for data center expansion.
4. Why developers are ditching GitHub for Codeberg and self-hosting alternatives
⭐ 149 💬 100 👤 Gedxx 🔗 Discuss on HN
An increasing number of developers are exploring self-hosted alternatives like Codeberg and Gitea as they seek to reduce dependence on GitHub. Concerns include corporate ownership by Microsoft, potential data access policies, API rate limits, and the desire for open, community-controlled infrastructure.
5. My Thoughts on the Bun Rust Rewrite
⭐ 70 💬 14 👤 kristoff_it 🔗 Discuss on HN
Andrew Kelley reflects on the decision to rewrite the Bun JavaScript runtime in Rust. He discusses the tradeoffs between Zig and Rust for systems programming, the engineering considerations behind the rewrite, and what the change means for Bun’s performance and developer experience.
6. I Built the Only 2026 WWII Jeep
⭐ 53 💬 11 👤 martey 🔗 Discuss on HN
An engineer took a bet on building the only WWII-style Jeep produced in 2026, facing numerous supply chain and manufacturing challenges along the way. The story documents the journey from prototype to a fully functional vehicle, driven by passion for historical automotive engineering and small-scale craftsmanship.
7. Cargo-nextest: 3x faster than cargo test, per-test isolation, first-class CI
⭐ 116 💬 30 👤 nateb2022 🔗 Discuss on HN
Cargo-nextest is a Rust test runner that delivers up to 3x faster test execution compared to the standard cargo test. It provides per-test isolation, parallel execution, and first-class CI integration — making it particularly valuable for large Rust codebases with slow test suites.
8. In-browser programmable robot simulator
⭐ 21 💬 0 👤 lijay 🔗 Discuss on HN
A fully in-browser programmable robot simulator lets users simulate the PETOI Bittle hexapod robot directly from a web page. It provides a low-friction environment for learning robotics programming, testing locomotion algorithms, and experimenting with sensor-driven behavior without any physical hardware.
9. How Donkey Kong Toppled Atari
