Crikey, it’s Ross @ross@crikey.social
Public

So, @tnashTim Nash and I moved to a private Mastodon instance on @mastohost

Despite following all the instructions, trying reboots
and re-running dead jobs, we are both WAY down on followers that haven’t redirected.

I’m at about 25% of my old followers from ross@fosstodon.org !!!

Is this normal? Did we do something wrong? Are they dead accounts? Do we need to just wait? Tips for fixing?

A friend does research on the history of nearby neighborhoods and then puts up posters with her findings. It never really occurred to me that I could do this - it's like bringing to "real life"! I would absolutely have defaulted to "make a website" but this physical sharing is much more delightful.

I need to find ways I can do this.

Do you have any examples in your life?

Headline:

"Mathematician solves algebra’s oldest problem using intriguing new number sequences.""

🤔

In the article:

"So, when we assume ∛7 'exists' in a formula, we’re assuming that this infinite, never-ending decimal is somehow a complete object. This is why, Prof. Wildberger says, he “doesn’t believe in irrational numbers.”

😬

Too bad this nonsense is getting publicity when there's so much real math to explain.

Mathematician solves algebra’s oldest problem using intriguing new number sequences

A mathematician has built an algebraic solution to an equation that was once believed impossible to solve.

心配されていたNHKの「フェイクとリアル 川口 クルド人 真相」(初回放送日：2025年4月5日)の再放送4/30深夜、主な修正は「日本人死ね」と発言したというデマ(実際は「病院行け」)について音声の専門家の鑑定でより明確にしたくだりの追加だったようです。
NHK plusでの配信も改めて始まりましたので、未見の方は改めてぜひ。

A Survey of AI Agent Protocols

The rapid development of large language models (LLMs) has led to the widespread deployment of LLM agents across diverse industries, including customer service, content generation, data analysis, and even healthcare. However, as more LLM agents are deployed, a major issue has emerged: there is no standard way for these agents to communicate with external tools or data sources. This lack of standardized protocols makes it difficult for agents to work together or scale effectively, and it limits their ability to tackle complex, real-world tasks. A unified communication protocol for LLM agents could change this. It would allow agents and tools to interact more smoothly, encourage collaboration, and triggering the formation of collective intelligence. In this paper, we provide the first comprehensive analysis of existing agent protocols, proposing a systematic two-dimensional classification that differentiates context-oriented versus inter-agent protocols and general-purpose versus domain-specific protocols. Additionally, we conduct a comparative performance analysis of these protocols across key dimensions such as security, scalability, and latency. Finally, we explore the future landscape of agent protocols by identifying critical research directions and characteristics necessary for next-generation protocols. These characteristics include adaptability, privacy preservation, and group-based interaction, as well as trends toward layered architectures and collective intelligence infrastructures. We expect this work to serve as a practical reference for both researchers and engineers seeking to design, evaluate, or integrate robust communication infrastructures for intelligent agents.

Initiative Hamburg Werbefrei @hhwerbefrei@bewegung.social
Quiet public

Niemand hat diese Unternehmen gezwungen, auf immer aggressivere, immer störendere Werbung zu setzen - bis wir uns genötigt sahen, eine Volksinitiative dagegen zu gründen.

Das war ihre Entscheidung. Warum sollen wir dafür verantwortlich sein?

Zwei Gegenfragen:

* Wieviele Beschäftigte haben die Werberiesen denn wegen der Digitalisierung der Anlagen oder z.B. wegen "KI" entlassen - oder eingestellt?

* Wieviele Arbeitsplätze bei kleineren Außenwerbern sind durch die Exklusivverträge mit STROER und WallDecaux in Hamburg weggefallen, wieviele Existenzen?

Die einzige konkrete Zahl, die unsere Kritiker nennen, ist die Gesamtzahl der Jobs in der gesamten Werbebranche.

Aber nur 5,7% der Werbeumsätze entfallen überhaupt auf Außenwerbung [1]. Und Hamburg Werbefrei richtet sich bekanntlich nicht gegen Außenwerbung per se.

Es gibt wohl keine Agentur, die so unkreativ ist, dass sie ausschließlich auf einer Art von Werbeträger werben kann.

Und die Werbewirtschaft ist nicht die einzige in Hamburg ansässige Industrie, andere Branchen suchen auch Fachkräfte.

Schwankungen in der Beschäftigtenzahl sind also allein in der Verantwortung der Unternehmen. Sie sind aber auch eine Funktion des Marktes, der,
wie der Fachverband selbst sagt [2], sehr unsicher ist.

Unser Einfluss wird massiv überschätzt, wenn man sagt, dass durch uns wegfielen. Es ist einfach Unfug.

In 2025, the internet will account for over half the advertising expenditure worldwide. TV, print, and outdoor media will round up the top four.
