Why yes, Claude, I *would* like you to enable all the additional Ruff checks I asked for, and then fix the resulting mess that you made in the first place.

- it loves to invoke shell scripts to do edits and ignore the MCP-provided editor tools I also just had to tell it to work in smaller batches so I can review its output. You can spec out a change as much as you like and it nearly always finds a way of becoming a slop cannon.

My personal observations of Claude Opus after using it for quite a while now: - it generally writes quite nice readable code - It is awful at organising code into reusable abstractions - for Python, it loves inline imports, and: - ignores my AGENTS.md telling it not to do that

@Canonical There wasn't really any more info in the Discourse post. Can you expand on the mitigations applied?

Australias social media ban is working well then!

I know Parliament is reluctant to wait for research and data but only a quarter of 14-15 years olds are complying with the social media ban in Australia. One result is that teens perceive 'compliers as less popular than non-compliers.'

‼️🚨 BREAKING: An AI found a Linux kernel zero-day that roots every distribution since 2017. The exploit fits in 732 bytes of Python. Patch your kernel ASAP. The vulnerability is CVE-2026-31431, nicknamed "Copy Fail," disclosed today by Theori. It has been sitting quietly in the Linux kernel for nine years. Most Linux privilege-escalation bugs are picky. They need a precise timing window (a "race"), or specific kernel addresses leaked from somewhere, or careful tuning per distribution. Copy Fail needs none of that. It is a straight-line logic mistake that works on the first try, every time, on every mainstream Linux box. The attacker just needs a normal user account on the machine. From there, the script asks the kernel to do some encryption work, abuses how that work is wired up, and ends up writing 4 bytes into a memory area called the "page cache" (Linux's high-speed copy of files in RAM). Those 4 bytes can be aimed at any program the system trusts, like /usr/bin/su, the shortcut to becoming root. Result: the next time anyone runs that program, it lets the attacker in as root. What should worry most: the corruption never touches the file on disk. It only exists in Linux's in-memory copy of that file. If you imaged the hard drive afterwards, the on-disk file would match the official package hash exactly. Reboot the machine, or just put it under memory pressure (any normal system load that needs the RAM), and the cached copy reloads fresh from disk. Containers do not help either. The page cache is shared across the whole host, so a process inside a container can use this bug to compromise the underlying server and reach into other tenants. The original sin was a 2017 "in-place optimization" in a kernel crypto module called algif_aead. It was meant to make encryption slightly faster. The change broke a critical safety assumption, and nobody noticed for nine years. That bug then rode every kernel update from 2017 to today. This vulnerability affects the following: 🔴 Shared servers (dev boxes, jump hosts, build servers): any user becomes root 🔴 Kubernetes and container clusters: one compromised pod escapes to the host 🔴 CI runners (GitHub Actions, GitLab, Jenkins): a malicious pull request becomes root on the runner 🔴 Cloud platforms running user code (notebooks, agent sandboxes, serverless functions): a tenant becomes host root Timeline: 🔴 March 23, 2026: reported to the Linux kernel security team 🔴 April 1: patch committed to mainline (commit a664bf3d603d) 🔴 April 22: CVE assigned 🔴 April 29: public disclosure Mitigation: update your kernel to a build that includes mainline commit a664bf3d603d. If you cannot patch immediately, turn off the vulnerable module: echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif.conf rmmod algif_aead 2>/dev/null || true For environments that run untrusted code (containers, sandboxes, CI runners), block access to the kernel's AF_ALG crypto interface entirely, even after patching. Almost nothing legitimate needs it, and blocking it shuts the door on this whole class of bug...

@rbtcollins None of that is anything to do with the coding issue mind 😀

When using Claude Opus to generate Python code, it loves using inline imports so much that it will ignore instructions in AGENTS.md to never do so on many occasions. I'm not sure how to stop it doing this now, this is very annoying.

@rbtcollins Interestingly, I am taking the reverse approach. I have a pipeline of agents and use the cheapest to triage, use another to give me a complexity assessment, and select a "work" model to run the triage output based on the assessment.

@rbtcollins It is not! Grappling with LLM instructions is universal though. I get the impression it treats instructions near the start and end of the prompt as more important.

@rbtcollins Yeah I am continually telling it when I review the changes. Annoying :( I don't really want the lazy loading as it affects mock patches too.

@rbtcollins Well - some are needed due to circular imports. Which I try very hard to not need, but ...

@jameinel TIL, thank you.

@code This is exactly the feature I was wishing it had lately. Nice work!
