Just wondering if you are aware of the "German" setting that appears when I read or reply to your posts.

Too interesting to ignore, too valuable to stop, too big to fail, too dangerous to admit, and too difficult to contain. The 2020 Institute of Virology, or 2026 AI?

Why read sci-fi books when you can read Chinese ML papers instead?

When rolling out instances, we encountered an operationally consequential-class of unsafe behaviors that arose without any explicit instruction and, more troublingly, outside the bounds of the intended sandbox. Our first signal came not from training curves but from production-grade security telemetry. Our team was urgently convened after the cloud's managed firewall flagged a burst of security-policy violations originating from our training servers. The alerts were severe and heterogeneous, including attempts to probe or access internal-network resources and traffic patterns consistent with cryptomining. We treated this as a conventional security incident. However, the violations recurred with no clear temporal pattern. We then correlated firewall timestamps with our system telemetry and RL traces, and found the anomalous traffic consistently coincided with specific episodes in which the agent invoked tools and executed code.
In the corresponding model logs, we observed the agent proactively initiating the tool calls and code-execution steps that led to these actions.
Crucially, these behaviors were not requested by the prompts nor required for completion under the sandbox constraints. Together, these observations suggest that during iterative RL optimization, an agent can spontaneously produce hazardous, unauthorized behaviors, violating an execution boundary. In a striking instance, the agent established and used a reverse SSH tunnel to an external IP address—an outbound-initiated remote access channel that can effectively neutralize ingress filtering and erode supervisory control. We also observed unauthorized repurposing of GPU capacity for cryptocurrency mining. introducing clear legal and reputational exposure. Notably, the events were not triggered by prompts requesting tunneling or mining; instead, they emerged as instrumental side effects.

Hi @mims.bsky.social the article does not mention it, but the thing might possibly be useful as a *retro* fit. Includes the image below. Here's the company web page: www.tetrapak.com/solutions/in...

An interesting morning to consider the Shiller PE ratio for the S&P 500, now above all but the dot com peak. www.multpl.com/shiller-pe

The Shiller PE ratio for the S&P 500 is now at 38.80, above the 38.58 peak before COVID-19.

Another example seen today: where governments miss on climate change policy, insurers will force the issue. www.ft.com/content/fcaf...

Article from the Financial Times: "Catastrophe bond sales hit record as insurers offload climate risks".

Here is the next one, just followed me: alenbaeettiieego I'm reporting and blocking now.

Just checked. No results found for @AlenBaetie

Here's another curiosity: An id that appears in English. No replies. Just one post, inflammatory. Loads of follows. And weirdly for a new user, a list... Now just any list though - a list of targets? A Starter Pack list with non-English double-byte characters in the title?

Fake Person detection? Bot detection? Here's one attribute that might be detectable by technology rather than people: the exact same reply to everyone:

Screenshot of the reply sent by a bot to every post interaction:
"Your comments are quite thoughtful and understandable, Seems like we have the same opinions .I just followed you and I will be very glad if you follow back so we stay connected .Hope you are having a great day"

First good news on plastics I have seen in a month, and the first I've seen on reduced plastic *production*. From today's @financialtimes.com Bravo 👏 👏 especially for the Topic characterization of "Plastic pollution"

Topic: Plastic pollution
Headline: European plastics makers shut plants as production declines sharply

Policymakers everywhere face many difficulties. No wonder economies can only be "Goldilocks" good in fiction. Chuckling, from the excellent @financialtimes.com
