Terence Eden reports that the UK's National Health Service (NHS) is preparing to close almost all of its open-source repositories as a response to LLM tools, such as Anthropic's Mythos, becoming more sophisticated at finding security vulnerabilities. He does not, to put it mildly, agree with the decision:

The majority of code repos published by the NHS are not meaningfully affected by any advance in security scanning. They're mostly data sets, internal tools, guidance, research tools, front-end design and the like. There is nothing in them which could realistically lead to a security incident.

When I was working at NHSX during the pandemic, we were so confident of the safety and necessity of open source, we made sure the Covid Contact Tracing app was open sourced the minute it was available to the public. That was a nationally mandated app, installed on millions of phones, subject to intense scrutiny from hostile powers - and yet, despite publishing the code, architecture and documentation, the open source code caused zero security incidents.

Furthermore, this new guidance is in direct contradiction to the UK's Tech Code of Practice point 3 "Be open and use open source" which insists on code being open.

We’re excited to announce the release of Zulip Server 12.0, containing hundreds of new features and bug fixes: end-to-end encryption for mobile push notifications, a major upgrade for Docker, configurable image previews, and much more! Almost 5,500 new commits have been merged across the project since the 11.0 release in August 2025.

Zulip is an organized team chat application ideal for both live and asynchronous communication. With Zulip, you own your data: it’s 100% open-source software, with easy migration between cloud hosting and self-hosting, plus a powerful API.

Syntax Highlighting

Edit v2 adds the Lightweight Syntax Highlighter. It has a ~40kB footprint for a dozen languages plus runtime, barely grows with each language added, and runs at >100MB/s.

The highlighter is based on a simple programming language that combines regular expressions with explicit control flow. It's designed such that the runtime can be easily ported to other languages, including JavaScript.

From 1.2.1 to 2.0.0, the edit binary size increased from 267 to 330 kB for win exe and 217 to 300 kB for linux binary.

What is edit? README intro:

A simple editor for simple needs.

This editor pays homage to the classic MS-DOS Editor, but with a modern interface and input controls similar to VS Code. The goal is to provide an accessible editor that even users largely unfamiliar with terminals can easily use.

Cisco Umbrella is cloud-delivered enterprise network security which provides users with a first line of defense against cybersecurity threats.

Ghostty, a modern GPU-accelerated terminal emulator developed by Mitchell Hashimoto, is transitioning its active development away from GitHub due to ongoing reliability issues that have disrupted daily workflows.

Hashimoto announced the decision in an emotional post titled “Ghostty Is Leaving GitHub,” stating that the project will gradually eliminate its dependency on GitHub while maintaining the current repository as a read-only mirror. Further details about the new hosting platform will be provided in the coming months, as discussions continue with both commercial and open-source providers.

In these uncertain and divisive times, we appreciate Anthropic offering support to the Blender project in the form of a Patron-level membership. This enables the Blender team to keep pursuing projects independently, and to focus on building tools for artists and creators.

In NetNewsWire 7.0.5 we made a change to get the feed image from RSS via the image element.
Weren’t we already doing this? Seems surprising that we weren’t!
It’s because, historically, these images were often rectangular — but the app wants square images. These days, probably due to the influence of mobile apps, images tend to be square, which is great. It means we can use these.
Note to feed publishers We suggest checking your feeds to see if they are supplying an image URL.

Germany's Sovereign Tech Agency (Sovereign Tech Fund) has provided critical financial resources to open-source software projects and maintainers the past several years. This has proven to be an incredible effort and today they announced their newest initiative as the Sovereign Tech Standards.

Sovereign Tech Standards aims to support open-source maintainers working on open standards and improving interoperability. Sovereign Tech Standards covers standards via the IETF, W3C, and ISO.
