The Peter Principle is a theory that employees are generally promoted to their level of incompetence.

In 1974, the author of the Peter a principle explained how he first got the idea and what can be done about it

Microsoft has released an open-source tool that helps teams learn ontology design before choosing a knowledge graph platform.

It is called Ontology Playground.

The project is a fully static React app, which means it does not need a backend, account system, database, or hosted service to run.

The goal is simple:

Help people understand what goes inside a graph before they buy or build the graph database.

Ontology Playground includes six pre-built domain ontologies:

→ Retail
→ Healthcare
→ Finance
→ Manufacturing
→ E-Commerce
→ Education

Each one gives users a starting point for understanding entities, relationships, properties, and how domain knowledge gets structured.

The app also includes a live visual designer, structured learning paths, hands-on labs, and RDF/XML export for Fabric IQ.

Because it is static, it can be deployed almost anywhere.

No backend.
No vendor lock-in.
No platform commitment upfront.

This matters because many teams jump into knowledge graphs too early.

They focus on the database first.

But the harder question is usually:

What should the graph actually know?

Ontology Playground teaches that layer first.

Code + 60-second demo (cvg demo refuses a dirty task, then a clean plan verifies the audit chain end to end):

Personal OSS project, still young. Feedback very welcome, especially on which gate you would want next.

AI coding agents lie about finishing work.

It says "done". You open the diff: TODOs, unwrap(), skipped tests.

So I built Convergio: a local Rust daemon that refuses an agent's "done" when the evidence does not match, and logs every refusal to a tamper-evident audit chain.

1/ Your AI coding agent says "done."
You open the diff: TODOs, unwrap(), skipped tests, hardcoded strings.
You redo it.
I got tired of that loop. So I built Convergio — a local Rust daemon
that refuses an agent's "done" when the evidence doesn't match.

Your AI agent says "done." It isn't. Bugs, no tests, pushed to main. I built a team of 85 AI specialists — architects, CFOs, security auditors — that plan, execute, and independently validate each other's work. Open source. For the solopreneurs

@sama @_dmca What about the rest of us, the world?

@AnthropicAI @DarioAmodei @DarioAmodei e’ ora di tornare alle radici, e’ ora di tornare in Europa e in Italia. / it’s time to consider coming back to the roots of your family: Europe and Italy, places where your values were born and still are alive and will be.

[Roberto D'Angelo @roberdan]

@ivanfioravanti Kitty. I’ll show you why later this morning ;-)

[Roberto D'Angelo @roberdan]

@ivanfioravanti @powerpig @julien_c @alxfazio @rstagi_ @tensorqt Is it confirmed tomorrow morning @ivanfioravanti ? If so, where and when? ;-)

[Roberto D'Angelo @roberdan]

@alxfazio Warp is pretty good @alxfazio
