Cyber Sword BBS: Building a Modern Linux BBS Inspired by the Dial-Up Era
May 18, 2026
A retrospective on building Cyber Sword BBS using Synchronet, Linux automation, FTN networking, and layered infrastructure inspired by classic dial-up era bulletin board systems.
Cray Supercomputers
May 10, 2026
Explore high-performance specialized computing systems in the Cray lineage, focusing on vector processing architectures, scientific workloads, and the shift from general-purpose flexibility to constraint-driven performance. Examine how physical limits, memory bandwidth, and data flow shape supercomputer design and how these principles persist in modern GPUs and distributed clusters.
Mainframes, Minicomputers and Microcomputers
May 03, 2026
Examine the three dominant computing models—mainframes, minicomputers, and microcomputers—and how differences in scale, ownership, and access shaped system design. Explore how centralized, departmental, and personal computing models coexist and how UNIX provides a cross-cutting abstraction across them.
Interfaces, Storage, and Early System Structure
April 26, 2026
Continue the foundations of computing by examining early interface systems such as punch cards, paper tape, and teletype terminals, along with early storage models and the emergence of time-sharing and structured computing environments that led toward system classification.
Foundations of Computation: From Mechanical Systems to Early Electronic Computers
April 19, 2026
Trace the foundations of computing from early calculation tools through mechanical and analog systems into digital logic, encoding standards like ASCII, and the emergence of system classification that shaped modern computing architecture.
