Time-Traveling Through Spark: Recording Distributed Failures Across Space and Time

Latest on memory safety: "The new US administration has removed everything from the White House web site and fired most of the CISA people who worked on memory safety."
tbf, memory safety is pretty woke.

We recorded Deepseek! Obviously this won't tell you how it was made, but very cool for seeing how it works. The only sad bit was that it doesn't seem to know about time travel debugging. youtube.com/watch?v=h-fJqXDS…

I'm going to respectfully disagree. I used to use debuggers more than I do now - I was enough of a fan of them that I wrote the Grand Universal Debugger control mode in Emacs.
In recent decades my preferences have changed. I use debuggers less and extensive debug logging more. That's an investment in the ability to troubleshoot future problems that often gains value over time.
What might get me back into them is time-reversal debuggers. Those sound interesting, but I haven't actually used one yet.

My friend Aditya Gurajada and I created a lightweight logging library (L3). Compared to standard printf debugging, L3 is much faster & lock-free -- 2ns per log message compared to > 50ns for a regular, buffered fprintf(). You can get it from github here: hubs.ly/Q02PZdlB0

A wrote a book on how debuggers work!
It guides you through writing a complete native debugger from scratch.
Available Spring 2025 from @nostarch (probably not with this cover)
ALT Cover for Building a Debugger by Sy Brand. It prominently features a cat with a blep and says "placeholder not final"
The CrowdStrike outage was super high profile, but this problem happens all the time: unsanitized input causes code to crash. Fuzzing is a good way to find these problems before your customer does (or in this case the whole world does). Ref. odbms.org/2023/08/on-debuggi…

CrowdStrike effectively bricked windows, Mac and Linux today.
Windows machines won’t boot, and Mac and Linux work is abandoned because all their users are on twitter making memes.
Incredible work.
Scary photo of me! But if you regularly battle with hard bugs like memory corruptions or concurrency issues, then you might find my short talk from C++ Online useful: hubs.ly/Q02Dr0vF0
