The Windows Kernel vs the Linux Kernel: Which is Better? ShopTalk!

YouTube Video

This Shop Talk episode features Dave and Glenn answering viewer questions about Dave’s recent videos on restoring a PDP-11. Key points include:

• PDP-11 Restoration Challenges: Dave discusses the lengthy compile and link times, using an emulator to test layouts before transferring to the real hardware, and encountering issues due to a different version of SIMH (a PDP-11 emulator) on his various machines.

• “Modern” Software on a PDP-11: Dave explains that while he can write modern-esque programs (like a Matrix screen saver and a sudo equivalent) in C, it’s impossible to run modern C++ code compiled for newer systems. His sudo implementation is available on GitHub. The screen savers are also available and showcased on his Twitter and Facebook.

• Unix vs. Windows Kernel Debate: Dave avoids declaring a “better” kernel, acknowledging the strengths of both the Unix subsystem model and the NT kernel’s ability to run multiple subsystems without hypervisors.

• Personal Anecdotes: Dave shares stories about his experiences with various operating systems (Novel Netware, VMS, RSX-11M, BSD), programming languages, and his casual conversation style.

• VI Editor Tips: Discussions include efficient ways to save and exit the VI editor (:x, :wq, ZZ).

• Dave’s Garage Update: Dave reveals that he’s currently working on integrating a KDA50 SDI controller (DEC’s version of SCSI) with his PDP-11, facing challenges in obtaining the necessary cables. He mentions a second YouTube channel, Dave’s Garage, and encourages viewers to subscribe.

• Other Projects: He mentions 3D printing replacement parts for his PDP-11 control panel and his “Mesmerizer” light, still available on eBay.

The overall tone is informal and conversational, reflecting Dave’s real-life speaking style. The episode largely revolves around the PDP-11 project and related anecdotes, demonstrating the challenges and rewards of working with vintage computing hardware.
