"slab_tiny" Boot Option Proposed For Tiny Linux Systems With Very Limited RAM

In 2022 the SLOB allocator was deprecated and removed with Linux 6.4 a year later. SLOB was popular with embedded systems with minimal amounts of RAM, so as a result the CONFIG_SLUB_TINY Kconfig option was then added for configuring the slab allocator for a minimal memory footprint for systems with 16MB of RAM or less. The CONFIG_SLUB_TINY is now on the chopping block with a proposed rework to the allocator code for making the "tiny" memory handling a boot time option...

Want to try Ubuntu’s AI dictation feature? Here’s how

Ubuntu’s new AI-powered dictation tool Myna isn’t officially ready, but you can give it an early test. Canonical has added the Myna orchestrator snap and a pair of speech-recognition AI models to the Snap Store recently, and made its new desktop Myna Settings tool available to test from a PPA. Ubuntu 26.10 also comes with another component preinstalled, as the gnome-shell-ubuntu-extensions package has a GNOME Shell extension that triggers an on-screen HUD when the Myna local AI speech-to-text tech is listening or transcribing. While a formal call for testing hasn’t been made, all the pieces needed to test Myna are […]

Ubuntu speeds up kernel security updates because of AI

Ubuntu kernel updates are about to get more frequent, as Canonical changes tack to keep pace with an ‘explosion’ in security vulnerabilities being discovered with AI tools. The company has announced it’s adopting a ‘unified’ two-week stable release update (SRU) cycle for kernel updates. This speeds up patching, testing and getting fixes for CVEs out to users. Previously, Canonical maintained kernel updates on a 4/2 schedule – a four-week regular cycle and a two-week security cycle. The new cadence takes effect from 28 September, 2026. Why a change is needed Canonical says the “explosion” in bugs and CVEs, driven largely […]

Ex-Microsoft dev’s new task manager supports Linux

The developer who made the original Window Task Manager app has vibe-coded a new system monitor app – and it works on macOS and Linux too. TMOG (Task Manager OG) might look like something mocked up by a design team to appear in the background of a cheap sci-fi movie – an aesthetic that years of US TV in the 1990s has programmed me to find cool – but it is a real, functional task manager. It’s created by Dave Plummer, who, in the 1990s, worked at Microsoft on the original Task Manager tool for Windows. To get TMOG from […]
