ARIEC61850 understands IEC 61850. ARStack61850 measures and executes IEC 61850 in real time.

The portable C++20 stack remains rooted in the ARIEC61850 behavioral model, but the project north star is now broader: build an open, deterministic IEC 61850 instrumentation platform for hardware-timestamped Sampled Values/GOOSE/PTP injection, analysis, commissioning and real-time closed-loop testing.

Earlier today, the PHP project released PHP 8.5.12, 8.4.27, 8.3.36, and 8.2.35. These releases fix two critical vulnerabilities that, under the right conditions, allow an unauthenticated attacker to execute code on servers running PHP. If you run PHP, it is imperative that you update now. The announcement on php.net contains and references technical details on the vulnerabilities, attack vectors, and instructions on how to update on which systems.

Most AI-generated files end up living somewhere completely different from where they were created. A chatbot can draft your task list or spec sheet, then you put it in a Google Doc, owned by a completely different company. Wherever you put the notes, that doc ends up with no idea about the conversation behind it. Then Anthropic launched its own editor inside Claude in September, which completely cuts out the middleman between AI synthesis and note-taking. I’ve been using it in regular chats and in Claude Code, and I think it might have started replacing Google Docs for me.

The first vulnerability is out-of-memory handling can interrupt PHP causing OOM corruption and remote code execution. The second remote code execution vector is via stale global state surviving after its backing memory has been freed.

Both of these remote code execution vulnerabilities are rated critical at 9.2 out of 10.

More details on these security vulnerabilities and the updated PHP versions at PHP.net.
