What happened to software optimization—and does understanding what's happening underneath still make you a better programmer?
In Shop Talk #85, Dave Plummer answers viewer questions about software optimization, engineering discipline, abstraction, and whether modern developers are losing touch with the fundamentals that once made software remarkably fast and efficient.
The discussion begins with a thoughtful viewer question about abstraction: should programmers simply embrace modern frameworks, or is it still worth understanding what's happening beneath the surface? From there, Dave shares stories from his years on Windows NT, including Microsoft's internal optimization tools like LEGO and BBT, how engineers measured performance, and why optimization was once considered a core engineering skill.
Along the way, Dave and Glen discuss software bloat, AI-generated code, memory usage, operating system design, retro computing, and a handful of follow-up questions from the recent slot machine episode.
Topics include:
• Should programmers still understand what's under the hood? • Why software optimization mattered • Microsoft's LEGO and BBT optimization tools • Modern software bloat • AI-generated code and performance • Windows NT engineering stories • Operating system design • ELKS, the RCA 1802, and retro computing • DOS/Windows easter eggs • Slot machine follow-up questions

What would 1996 Dave think of rebuilding Task Manager with AI? Dave and Glen celebrate 100 episodes of Shop Talk with Windows stories, retro computing, fresh viewer questions, and a look at the community behind the show.Across the first 99 episodes, our comment archive contains more than 23,000 comments. We recognize some familiar contributors, revisit the rebuilt Task Manager episode’s response, and share the most-liked comment in the archive.Then it’s back to your questions: how overlays helped programs fit into limited memory, porting Colossal Cave to a PDP-11, getting started with AI, checking AI-generated code, and using AI for business strategy.Plus: a difficult day at Microsoft, whether Spy++ deserves a modern makeover, TMOG follow-ups, missing hard-drive activity lights, and Deluxe Asteroids.Thank you to everyone who has watched, commented, and kept the conversation going.
Windows war stories meet AI-assisted retro computing in this week’s Shop Talk. Dave and Glen explore AI development on the PDP-11, how they prompt and review generated code, and what older computers can still teach us.Dave discusses improving top for BSD, compiler changes for ksh, and getting Samba running on a 16-bit machine. Viewer questions cover detailed specifications, native apps versus Electron, ownership of AI-generated code, and improving PDP Gary.We also revisit Microsoft Bob’s connection to the Windows XP disc, instant shutdown shortcuts, and a CHKDSK job that could run for days. Plus: TMOG memory usage and temperature graphs, lessons from the TRS-80, Windows 3.1 on modern hardware, and Tempest with a joystick.
PDP Gary has a personality—but how did Dave define it? This week on Shop Talk, Dave and Glen start with Gary, then explore Dave’s recent work using AI on BSD, the PDP kernel, and its peripherals.
