Generate Time-Sortable IDs with Python 3.14’s UUID v7

Problem

UUID4 generates purely random identifiers that lack chronological ordering.

Without embedded timestamps, you need separate timestamp fields and custom sorting logic to organize records by creation time.

Solution

Python 3.14 introduces UUID version 7 with built-in timestamp ordering.

Key features:

• Determine creation order by comparing two UUIDs directly
• Retrieve exact creation time by extracting the embedded timestamp

Build Human-in-the-Loop AI Agents with LangChain

Problem

Without human oversight, AI agents can make irreversible mistakes by executing risky operations like database deletions.

Solution

LangChain v1.0’s interrupt() function pauses agent execution at critical decision points for human review.

How it works:

• interrupt() pauses tool execution for human review
• MemorySaver checkpointer enables pause/resume functionality
• Human reviews proposed action and approves or rejects
• Command(resume=…) continues execution after approval

This gives you full control over critical AI decisions before they execute.
