Tony Hoare: "Software error is a form of lower back pain" 😅

The Science of Computing and the Engineering of Software - Tony Hoare - 2009/05 www.youtube.com/watch?v=buvl...

Sir Tony Hoare has passed. He gave us Quicksort and the logic underpinning modern concurrency. Yet, he’s most famous for what he called his "billion dollar mistake": the null reference. A titan who shaped every line of code you've ever written. #programming 1/4

Writing a .NET Garbage Collector in C#  - Part 8: Interior pointers 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.

I published part 8 of my "Writing a .NET Garbage Collector in C#" series. The subject this time is interior pointers: what are they, and why are they so challenging for the GC.

Microsoft HoloLens finds second home in the military after failing battlefield tests Let’s hope air cargo checks don’t trigger the same headaches The US Army's attempt to turn Microsoft HoloLens headsets into battlefield kit may have failed, but the AR goggles aren't going into the garbage. Instead, they're being repurposed for remote cargo inspection support.…

Tree view with the processes on the left, timeline of exceptions in processes up top, data grid with the exception details in the center and current exception call stack at the bottom

PerfView can record all managed exceptions in all processes system-wide thanks to the .NET ETW provider, with callstacks.

I built a viewer for these .etl files:

Doing just that in Windows file explorer - 5 thick files returned

Did you know if you type size:gigantic into file explorer search it will show you the really large files? 👀

would you help me to make this list more 'complete'? @dcbrock.bsky.social @davidcmurphy.bsky.social

Too good to be true: an unexpected profiler trap Sometimes the most convincing performance gains deserve a second look. A reminder that profiling data can be more subtle than it first appears.

It's not specific to PerfView though, in theory this could happen with any profiler.
