A dev dives into building a barebones Linux distro for RISC-V using QEMU. Starts at the metal: compiles the kernel, wires up a no-frills init process, packs it all into an initramfs. Then levels up, drops inu-rootto swap out raw shell scripts for Go-powered userland tools. Adds network. Now it’s a f.. read more  

Canonical has launched Minimal Ubuntu Pro, enhancing cloud security with lightweight images and robust features. Available on AWS, Azure, and Google Cloud, it offers minimized attack surfaces and long-term support.

Anthropic invests $1.5 million in the Python Software Foundation to boost Python ecosystem security. The funding targets improvements in CPython and PyPI, including new tools for package review and malware datasets. It also supports the PSF's core activities and community initiatives.

Anthropic's new Economic Index report introduces five "economic primitives" to measure *how* Claude is used: task complexity, user and AI skill level, use case (work, coursework, personal), autonomy, and task success - built from privacy-preserving classification of anonymized Claude.ai and first-party API transcripts from **November 2025**.
