The Netherlands is Quietly Building Its Own GitHub Replacement") Article It's Foss·17w Go Away Microsoft! The Netherlands is Quietly Building Its Own GitHub Replacement The Netherlands is building a sovereign, self-hosted Git platform for government source code using Forgejo, a fully open source forge licensed under GPLv3+. GitHub was ruled out for being proprietary, and GitLab for its open-core model. The platform, code.overheid.nl, soft-launched on April 24, 2026, and is already hosting repositories from the Dutch Electoral Council, the Ministry of the Interior, and several municipalities. Still in pilot phase, it aims to reduce duplicate development across agencies and give the government full control over its infrastructure. 199 22 2. 2 [](https://daily.dev/posts/this-new-terminal-is-absurd-but-totally-fun--cqshosfcd "This New Terminal is Absurd (But Totally Fun)") Article It's Foss·16w This New Terminal is Absurd (But Totally Fun) Ratty is an experimental GPU-rendered terminal emulator written in Rust that integrates the Bevy game engine to enable 3D graphics inside the terminal. Key features include a customizable 3D rat cursor, a 3D mode that lets you view terminal output from different angles, a Mobius strip mode, inline 3D object anchoring via a custom Ratty Graphics Protocol, Kitty Graphics Protocol support for images, a live 2D-to-3D split-pane drawing demo, and an interactive document mode inspired by TempleOS. Installation is available via Cargo, pacman on Arch Linux, or prebuilt binaries. A GPU is required to run it. The project is explicitly experimental and resource-heavy, not intended as a daily driver. 187 26 3. 3 [](https://daily.dev/posts/i-gave-desktop-email-clients-another-shot-and-this-new-app-delivered-kiy5sdo0n "I Gave Desktop Email Clients Another Shot and This New App Delivered") Article It's Foss·16w I Gave Desktop Email Clients Another Shot and This New App Delivered Aerion is a new open source desktop email client for Linux (and other platforms) built with Wails and Svelte instead of Electron. It supports multiple accounts, conversation threading, a WYSIWYG composer, contact sync via CardDAV/Google/Microsoft, and works with Gmail, Outlook, Proton Mail, iCloud, and generic IMAP/SMTP. The app holds a CASA Tier 2 security certification and collects no telemetry. A hands-on first look reveals smooth Gmail OAuth setup, blocked remote images by default, and vim-style keyboard shortcuts, but notes issues with no desktop notifications, no configurable sync interval, and a dismissible account-setup dialog with no warning. It is available on Flathub and GitHub as pre-release software. 70 2 4. 4 [](https://daily.dev/posts/typical-microsoft-turns-out-vs-code-was-adding-copilot-as-a-git-co-author-without-telling-anyone-ddcgwovcl "Typical Microsoft! Turns Out VS Code Was Adding Copilot as a Git Co-Author Without Telling Anyone") Article It's Foss·17w Typical Microsoft! Turns Out VS Code Was Adding Copilot as a Git Co-Author Without Telling Anyone VS Code quietly began adding a 'Co-authored-by: Copilot' trailer to git commits after a pull request in April changed the default value of the git.addAICoAuthor setting from 'off' to 'all'. This meant any user who hadn't manually configured the setting had Copilot credited in their git history — even on commits written entirely without AI assistance. The trailer also appeared when Copilot features were explicitly disabled, and was appended after commit finalization with no chance to review it. A VS Code team member acknowledged the mistake on Hacker News, apologized, and a fix reverting the default back to 'off' has been merged and is expected in VS Code 1.119. 55 8 5. 5 [](https://daily.dev/posts/ubuntu-s-official-flavour-list-is-shrinking-and-that-s-not-a-bad-thing-9ffwjbcxk "Ubuntu’s Official Flavour List Is Shrinking, And That’s Not a Bad Thing") Article It's Foss·18w Ubuntu’s Official Flavour List Is Shrinking, And That’s Not a Bad Thing Ubuntu's official flavour count is shrinking with the 26.04 LTS release, and the author argues this is a healthy correction rather than a loss. The piece examines why maintaining official flavour status requires real engineering resources, QA participation, and sustained maintainership — not just community enthusiasm. Examples like Ubuntu MATE's leadership crisis, Lubuntu's reduced manpower, and Ubuntu Unity missing key milestones illustrate the strain. The argument is that a leaner, well-supported official flavour list better serves users and maintainers alike, while the broader Linux ecosystem still offers unlimited community remixes and spins. 40 4 6. 6 [](https://daily.dev/posts/rust-could-eliminate-80-of-linux-kernel-cves--72m3rwq8v "Rust Could Eliminate 80% of Linux Kernel CVEs!") Article It's Foss·15w Rust Could Eliminate 80% of Linux Kernel CVEs! Greg Kroah-Hartman, Linux stable maintainer, presented at RustWeek 2026 a proposal that could eliminate roughly 80% of Linux kernel CVEs. The core idea is a new Rust type called \`Untrusted\`, developed with Benno Lossin, which attaches a compile-time marker to data arriving from user space or hardware. This forces explicit validation before the data can be used, with no runtime overhead. Rust already addresses around 60% of kernel bugs by catching unchecked error returns and forgotten lock releases at compile time. The \`Untrusted\` type is not yet merged — it requires changes to the Rust compiler and depends on related work on field projections. Greg called for more Rust kernel developers to help move the effort forward. 21 7 [See all It's Foss archives](/sources/itsfoss/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/itsfoss/best-of/2026/05#page","url":"https://daily.dev/sources/itsfoss/best-of/2026/05","name":"Best It's Foss Posts — May 2026","description":"The most upvoted It's Foss posts from May 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/itsfoss/best-of/2026/05#items","numberOfItems":6,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/go-away-microsoft-the-netherlands-is-quietly-building-its-own-github-replacement-terk236fn","name":"Go Away Microsoft!
