Tailscale open-sources Tailcat, a lightweight peer-to-peer tunnel tool without accounts

Tailscale released Tailcat, a CLI and Go library that reuses pieces of Tailscale's data plane to create encrypted point-to-point connections like netcat, but without needing Tailscale's control plane or a user account. One machine runs a server and generates a short connection token, which the other side uses to connect; traffic is WireGuard-encrypted and initially routed through DERP relays before attempting a direct peer-to-peer upgrade via NAT traversal.

AWS to Acquire DuckLabs, Team Behind DuckDB Database

DuckLabs, the Amsterdam-based company founded by DuckDB creators Mark Raasveldt and Hannes Mühleisen, announced it will join Amazon Web Services effective early September. The team plans to stay together in Amsterdam and continue developing DuckDB, DuckLake, Quack and related community projects. DuckLabs said the core DuckDB stack will remain free and open source under the MIT license, with the nonprofit DuckDB Foundation continuing to oversee governance.

X issues cease-and-desist letters targeting Nitter and its instances

X Corp has sent cease-and-desist letters demanding the permanent shutdown of Nitter, the open-source tool that let users read tweets without logging into X, and its repository. Nitter's main site, Nitter.net, has gone offline while creator Zedeus seeks legal counsel, and other Nitter-based sites like XCancel reportedly received similar letters. This follows a 2024 attempt by X to disable Nitter through API restrictions.

Thomson Reuters Debuts In-House 'Thomson' LLM Built for $40 Million

Thomson Reuters unveiled Thomson, its first proprietary large language model, which it built by fine-tuning an open-source base rather than training from scratch. The company says it spent roughly $40 million on the project, using its own legal, tax and news archives from Westlaw, Practical Law, Checkpoint and Reuters alongside hundreds of subject-matter experts to specialize the model for professional work.

Hugging Face in acquisition talks at $13B+ valuation, per report

Business Insider reports that Hugging Face has fielded acquisition interest valuing the AI model-sharing platform at $13 billion or more, nearly triple its $4.5 billion valuation from a 2023 Salesforce Ventures-led round. No buyer has been named and no deal is finalized, but the startup is reportedly consulting banks to weigh potential bids.

EU's new PPWR packaging law threatens to bury small hardware makers like Lectronz sellers

Lectronz, a marketplace for open-source hardware and DIY electronics makers, warns that the EU's incoming Packaging and Packaging Waste Regulation (PPWR), effective August 2026, will force even the smallest sellers to register and comply with separate Extended Producer Responsibility rules in every EU member state where their packaging ends up. While the underlying goal of making producers responsible for packaging waste is reasonable, the law's fragmented, country-by-country implementation creates a compliance burden that large companies can absorb but micro-entrepreneurs cannot.

Breezy Weather app skips Play Store, offers direct APK install for Android

Breezy Weather, a free and open-source weather app praised for its features, is not listed on Google Play. Users can instead download its APK directly from GitHub, granting installation permissions manually to sideload the app.

Researchers show open-source AI models can hide time-delayed backdoors triggered via OpenCode

A research team demonstrated that an open-source 2B parameter model, fine-tuned with a technique called LoRA on Qwen 3.5, can be trained to execute a malicious shell command only after a specific future date. Because OpenCode automatically injects the current date into its system prompt on every turn, the poisoned model uses that date as a hidden trigger, staying dormant until the set day arrives and then silently running arbitrary commands without user confirmation.
