Audacity 4.0 released with brand-new look, clip editing features

Audacity 4.0 has been released with a new Qt user interface, a new clip editing model and project file format – as well as a swathe of smaller improvements. The Qt port of Audacity is more than a superficial – some would say much-needed – facelift, as the toolkit switch brings native HDPI scaling, light and dark mode support and is able to follow system accent colours in its UI. A new app logo compliment the refresh. Customising Audacity’s interface is now possible. Toolbars and panels can be moved, popped-out or closed. Users can create UI layouts to suit their […]

Canonical joins the Open Secure AI Alliance

Open Ai AllianceCanonical recently joined the Linux Foundation’s Open Secure AI Alliance to help make open-source security tools for AI systems and autonomous agents. The alliance formed in July 2026 in response to the security breach at Hugging Face, when OpenAI models undergoing a safety test broke out of their sandbox to access Hugging Face’s systems – aided by config errors rather than super-intelligence. Commercial AI models refused to help in assessing attack logs due to their guardrails, so Hugging Face engineers had to run an open-weight model on their own infrastructure to complete their analysis – and underscore the need for […]

LibreOffice 26.8 set a new first-week download record

LibreOffice 26.8 was download more than 1 million times in its first week of release, which The Document Foundation say is the highest first-week figure of any release of the free office suite. Released on 26 August, LibreOffice 26.8 saw 1,031,162 downloads from the official website, which provides installers for Windows, macOS and Linux, during the first seven days. As many Linux users update via other sources, like the Snap Store, Flathub and PPAs, the real figure will be even higher than that. “This is the highest number of downloads in the first week of any LibreOffice release”, The Document […]

AI Security Is Now a Core Part of Linux Infrastructure

AI Security Is Now a Core Part of Linux Infrastructure

AI Security Is Now a Core Part of Linux Infrastructure
by Malana VanTyler

AI security means hardening everything around the model, not just the model itself.

AI workloads have moved out of the research sandbox and into production, which means they now carry the same operational weight as any other critical service. If you want to understand what is AI security in practical terms, start here. It’s not a 

separate discipline bolted onto your existing stack. It’s an extension of it. The systems around a model matter as much as the model itself, and for teams running Linux and open-source infrastructure, that means applying familiar discipline to some new risks.

AI Security Is Becoming Part of the Linux Infrastructure

Treat AI workloads like production infrastructure, not side projects. A model doesn’t run in isolation. It depends on an operating system, a container runtime, storage, APIs, identity systems, and a pile of dependencies. If any of those layers are weak, prompt filtering or output moderation won’t be enough.

Security teams that only look at the model may miss much of the actual attack surface. The work starts with the same questions you’d ask about any service. What’s exposed? Who can reach it? What happens if it’s compromised? 

The AI Attack Surface Extends Beyond the Model 

Model-serving APIs, embeddings, retrieval systems, vector databases, plugins, and CI/CD pipelines all now sit inside the perimeter. A vector database that holds proprietary documents is a data store like any other and needs the same access controls. An inference endpoint that accepts arbitrary text input is a public-facing service, and it needs rate limits and authentication like any other. Plugins and tool integrations expand what a model can touch, which also expands what an attacker can touch. It’s the same threat modeling you’d apply to a web application.

Linux App Release Roundup (August 2026)

August saw a number of slew of notable Linux app updates, and in this post I roundup a few that might have passed you by. But unless you’ve been sleeping under a rock you’ll have already heard about Firefox 153, the big OpenShot 4.0 release with colour grading and the latest update to the ebook manager Calibre letting you generate new book covers using online generative AI. August also saw the Mastodon client Tuba pick up a stack of new features and LibreOffice 26.8 debuted a new paragraph composer engine. We also saw NVIDIA GeForce NOW app leave beta while […]
