Conceptual, architectural explainers — how a subsystem actually works underneath.
A systems-level guide to POSIX terminal input processing, canonical and noncanonical reads, echo, signals, control characters, job control, and restoration.
A patent- and process-aware history of Jack Kilby's 1958 demonstration, Robert Noyce's planar interconnection concept, and integrated-circuit manufacturing.
The documented story of Busicom's calculator request, Intel's MCS-4 architecture, Faggin's silicon implementation, the 4004 launch, and its limits.
A careful chronology of public-key ideas at GCHQ, Diffie and Hellman's 1976 publication, Merkle's contribution, RSA, signatures, and attribution.
What the 1988 Patterson-Gibson-Katz RAID paper actually proposed, how its levels organized tradeoffs, which ideas predated it, and why naming mattered.
A careful history of Berkeley RISC and Stanford MIPS, their compiler and pipeline assumptions, register strategies, measured claims, and commercial descendants.
A protocol-level history of ARPANET's NCP-to-TCP/IP transition, the planning RFCs, host conversion, gateways, DNS timing, and what flag day did not mean.
A source-grounded history of the 1947 Bell Labs transistor, Bardeen and Brattain's point-contact result, Shockley's junction design, and scale-up.
A documented Unix history from Multics and the PDP-7 through Thompson and Ritchie's file model, pipes, C rewrite, 1974 paper, and licensed diffusion.
How Tim Berners-Lee's 1990 NeXT application combined browsing and authoring, which Web components it implemented, and why later browsers narrowed the model.
