Don’t be the one putting your company at risk 😳

Most meetings include confidential data - from project details to client information.

But not every AI notetaker protects that information with the security your company deserves.

If the AI notetaker you’re using trains their AI models on your team’s conversations, you could be putting your company at risk without realizing it.

This AI Meeting Notetaker Security Checklist helps you avoid that.

In just two minutes, you’ll learn the 7 checks to ensure your team’s AI meeting notes stay private and secure.

Don’t let your meetings become someone else’s dataset.

How Dropbox Built an AI Product Using RAG and AI Agents 🤖

Dropbox created Dash, a unified search and knowledge layer that sits on top of various business tools like emails, files, chats, and calendars. This AI-powered system helps teams cut through information overload by providing intelligent search, organization, and secure sharing capabilities across different data sources.

The challenge: Building an enterprise AI system that can handle diverse data formats, fragmented sources, and multiple modalities while maintaining security and accuracy at scale.

Implementation highlights:

• Hybrid retrieval strategy: Combined lexical search with semantic reranking for fast, accurate results

• Custom interpreter: Built secure environment for AI agents to execute validated code plans

• RAG pipeline: Grounded LLM responses in real documents to prevent hallucinations

• Multi-phase agents: Implemented planning and execution phases for complex workflows

• Strict validation: Added static analysis and runtime checks to ensure reliable operation

Results and learnings:

• Fast responses: Achieved sub-2 second retrieval for 95% of queries

• Flexible architecture: Created model-agnostic pipeline supporting different LLMs

• Enhanced accuracy: Successfully combined RAG for lookups with agents for complex tasks

The key takeaway is that enterprise AI requires a thoughtful balance between speed, accuracy, and security. Dropbox's approach shows how to combine RAG and AI agents effectively while maintaining strict control over execution.

This week’s coding challenge:

This week’s tip:

Use NGINX's proxy_cache_use_stale directive to serve stale content during backend failures or updates, implementing a robust circuit breaker pattern. This provides graceful degradation by serving slightly outdated content instead of errors when your backend services are struggling.

Wen?

• High-traffic applications: Maintains service availability during traffic spikes or backend failures

• Zero-downtime deployments: Serves cached content while new backend instances warm up

• Microservices architectures: Prevents cascading failures when dependent services experience issues
