Dave’s Garage: Shop Talk

Show Notes

What does it really mean when programmers say "everything is a file"?

In Shop Talk #84, Dave Plummer and Glen Hodges answer viewer questions inspired by the recent fopen() discussion and explore one of the most influential ideas in computing: abstraction.

The conversation begins with a question about why computer science classes often feel disconnected from real-world software development before diving deep into file descriptors, FILE pointers, pipes, devices, mmap, Unix philosophy, and the surprising design decisions that shaped modern operating systems.

Topics include:

• Why CS classes don't always reflect the real world • Learning programming in the age of AI • Neurodiversity and problem solving • fopen(), FILE*, and file descriptors • Pipes, devices, and streams • DOS versus Unix approaches to I/O • Why "everything is a file" became such a powerful idea • Whether we'd design operating systems the same way today

Plus a few slot-machine questions, Flying Spaghetti Monster sightings, and other classic Shop Talk detours.

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.
