After all, if they’re marked as unsafe, there’s gotta be a reason, right?

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.

In this post I provide an introduction to Device Bound Session Credentials, I look at how DBSC protects against session hijacking, and how the protocol works

This issue includes bits of AI, Security, MS SQL, Performance, C#, HTTP and of course .NET and .NET Internals.

Using NativeAOT to write a .NET GC in C#. In this part, we add support for finalization.

This issue includes bits of AI (too much AI), C#, software development, architecture, Windows, security, NTFS and of course .NET and .NET Internals.

This issue includes bits (or I would rather say bytes) of AI, bits of software development, operating systems, web, diagnostics, performance, C++, C#,  and of course .NET and .NET Internals.

Using NativeAOT to write a .NET GC in C#. In this part, we look at what the GC must do to properly handle frozen segments, and we change the allocation strategy to make it more efficient.

Using NativeAOT to write a .NET GC in C#. This time, we look at what interior pointers are and why they’re so difficult for the GC.

Sometimes the most convincing performance gains deserve a second look. A reminder that profiling data can be more subtle than it first appears.

Using NativeAOT to write a .NET GC in C#. In the seventh part, we scan and update the handles during the mark phase of the garbage collection.

Using NativeAOT to write a .NET GC in C#. In the sixth part, we start implementing the mark phase of the garbage collection.

A short investigation that showcases one of the most common problem faced when writing a profiler.

In this post I look at how to create a simple .NET profiler. But instead of using C++, the profiler uses C# and NativeAOT with the Silhouette library

In this article, we see what are function hooks, and how to use them in .NET with Silhouette. We also learn how to statically link a library with NativeAOT.

In 2021 I found a huge memory leak in VS code, totalling around 64 GB when I first saw it, but with no actual limit on how high it could go. I found this leak despite two obstacles that should have…

A walkthrough of how I built a custom profiler to measure UI responsiveness, using .NET and Silhouette.
