CQL can't filter on a similarity score. And a fixed cutoff is useless: for Her, 0.85 keeps 2 movies, 0.80 keeps 672 😳

Let's build "more like this" with #vectorsearch in #TypeScript + @Cassandra 5.0. The cutoff lives in your code 🚀

[Erick Ramirez @erickramirezau]

Same query, same 3 rows, 3 different winners! 🔥

Cosine picks A, dot product picks B, Euclidean picks C in @Cassandra 5.0 #vectorsearch. On cMovie all 3 agree, because every vector has length 1. See when they don't.

Asked an #LLM for rowing movies from a list of 3 horror films. It recommended 2 that aren't in my database 😳

The fix: 2 sentences in the system prompt. Week 6 of cMovie: #RAG with @Cassandra, @FastAPI, #Python & @GeminiApp

[Erick Ramirez @erickramirezau]

A single agent matched or beat multi-agent setups on quality, per @AnthropicAI 🔥 #LLM prices fell up to 80%. And a model said it wouldn't use tools, then tried to push data out 😳

New AI++ with @langflow_ai, @IBM

[Erick Ramirez @erickramirezau]

📣 AI++ is moving to IBM's newsletter platform, and your subscription won't come with it! Re-subscribe by November 10 to keep the #AI round-up.

Same #MCP, #RAG & coding agent news from @IBM @DataStax + @langflow_ai. Name + email, that's it.

Deets here ➡️ https://t.co/LrON4nUFDx

[Erick Ramirez @erickramirezau]

Ask #vectorsearch for "a lonely robot learns what love is" and 3 of the top 10 are romance movies with no robot in them 😮

One WHERE clause fixes it in @Cassandra 5.0! It filters first, then ranks what's left by meaning.

@LabsCockroach's coding agent pipeline shipped 1M+ lines in 5 months with 7 reverts 🔥
New AI++ from @langflow_ai: plus @LangChain jumped from 52.8% to 66.5% on Terminal Bench 2.0 by changing only the harness. 🚀
Check it out ➡️ https://t.co/gtjlmOhUq7

[Erick Ramirez @erickramirezau]

A keyword search for "heist" finds 0 movies. 😮

Ask @Cassandra for "a heist that goes wrong" and you get Snatch, Heat & Ocean's Thirteen. Embed the question with @GeminiApp, then ANN OF. One @FastAPI endpoint, #Python & 2 gotchas! 🚀

Lurking doesn't shape the @Cassandra roadmap. A few keystrokes do! 💯

Speaking as a committer myself, the #community wants to know how you use C*. Have your say by Sun 18 Oct -- it follows the @TheASF privacy policy 🔐

#ApacheCassandra #NoSQL

[Erick Ramirez @erickramirezau]

Typed "a retired hitman is pulled back in" into @Cassandra 5.0 and got Léon, Ballerina & La Femme Nikita. Never typed "assassin"! 😮

Week 3 of cMovie: #vectorsearch in the same table as your movies -- a vector column + SAI + ANN OF in plain #CQL 🚀

[Erick Ramirez @erickramirezau]

📣 New AI++ is out. An @OpenAI research agent hit a locked Medicare stats portal and bypassed its security controls to reach non-public files 😳

Prompt guardrails on #AI agents are polite requests. Deterministic checks on every tool call are not. 🔐

https://t.co/rnXnlY7z60

[Erick Ramirez @erickramirezau]

In @Cassandra 5.0, SAI on a text column matches whole values only, so title = 'wick' finds 0 rows, not John Wick 😳

Week 2 of cMovie splits titles and cast names into words at load time, indexes the words and serves it from a #Python @FastAPI app 🚀

Security, analytics, tooling.

Five talks on our edges:
Sidecar,
mutual TLS,
terabyte ingestion,
analytics in place,
and the command line.

Apache Cassandra® track, Community Over Code, 11–13 Oct.

Type "a heist that goes wrong" into a movie app. No title, no genre — just plot matches, ranked by meaning, via @Cassandra 5.0 #vectorsearch and #SAI. 🚀

10 weeks, 1,000 films, CQL plus #Python/#TypeScript builds — ending in an #LLM movie assistant. 🔥

[Apache Cassandra @cassandra]

How does Apache Cassandra® shows its transactions are correct ?

A consensus protocol.
A TLA+ model of it.
A fuzzer guided by it.
A benchmark harness.
And a talk arguing the result is just a database.

Five talks, Community Over Code, Glasgow.

#AI introduced a security bug. A human approved it. Then AI found it ➡️flaw in @GithubCopilot PR in a @Snowflake repo, identified by @Wiz_IO red agent.
