GitHub Copilot exposes two very different hook surfaces: a rich Copilot CLI stream with weak identity and derived turns, and a thin VS Code agent-hooks Preview with exact tool and agent IDs.

How Claude Code hooks differ from Cursor: broader lifecycle and permission telemetry, strong native IDs, batch and compaction events, but no thought or specialized execution hooks.

How to correlate Cursor hook events into sessions, turns, concurrent tool and MCP calls, detect skill usage, and build useful summaries without pretending the reconstruction is perfect.

How I used Cursor agent hooks to observe prompts, thoughts, tool calls, MCP executions, file edits and subagents without changing the agent's behavior.

From a 2007 Windows via C/C++ VMMap demo to a modern Windows 11 analyzer and its Linux /proc/smaps counterpart - and why Working Set, RSS/PSS and 'committed' memory do not mean the same thing on the t...

This issue includes bits of AI, software development, C++, C#, diagnostics, architecture and of course .NET and .NET Internals.

Why .NET is replacing the DAC with the cDAC data contracts, how they work locally / over a process / from a dump, and how to map the GitHub .md contracts to C# - with a from-scratch !eeheap as a worki...
