Part 6 in a series.Our simple control loop from Part 5 can be controlled with a few commands. These commands can have a textual representation, exposed-for example-through a rudimentary command-line interface (or similar):bp X, to set an address breakpoin

Rambling on stream led me to a topic I hope to flesh out in writing soon-the "zero point"-and how the path to the best designs is never adding arbitrary amounts of code to a project forever. Instead, the most powerful, useful, and rock solid solutions are

I was recently asked on stream about base layer concepts in the RAD Debugger codebase which has been a useful building block for the many asynchronously-managed caches that the debugger needs for the purposes of evaluation and larger data visualization, w

Part 5 in a series.Now that we've seen how a debugger modifies a debuggee (using the kernel and CPU features), let's put these pieces together and see how we might implement both breakpoints and instruction-level stepping in a basic debugger.The Control L

Part 4 in a series.I covered in Part 3 that debuggers help analyze programs-"debuggees"-both by reading from, and writing to, them. The kernel exposes features which facilitate this bi-directional flow of information. A debugger can receive debug events,

The Death of UsenetUsenet is a decentralized message board network created in 1980. Predating the World Wide Web's ubiquity, Usenet was inhabited by a small and exclusive population from universities, laboratories, or other prestigious institutions. The g

I recently had the pleasure of hopping on a call with Sam Smith, creator of the Serenum operating system, and one of the organizers of the Better Software Conference. We talked about operating system design-specifically, the boundary between operating sys

Engine programmer at Epic Games Tools, opinions my own. Working on tools, engines, and games.

Learning to program a single CPU core is difficult. There is an enormous number of techniques, amount of information, and number of hours to spend in order to learn to do it effectively. Learning to program multiple CPU cores to do work in parallel, all w

When streaming programming recently, I was asked about a multithreaded radix sort that I had implemented for a part of the RAD Debugger with the help of Mārtiņš Možeiko and Nikita Smith (creator of the RAD Linker). In answering the question, I covered the
