IBM’s Latest Quantum Supercomputer Idea: The Hybrid Classical-Quantum System
Although quantum processors exist today, they are still a long way off from becoming practical replacements for classical computers. This is due to many practical considerations, not the least of w…
First Draft of a Report on the EDVAC - Wikipedia
The First Draft of a Report on the EDVAC (commonly shortened to First Draft) is an incomplete 101-page document written by John von Neumann and distributed on June 30, 1945 by Herman Goldstine, security officer on the classified ENIAC project. It contains the first published description of the logical design of a computer using the stored-program concept, which has come to be known as the von Neumann architecture; the name has become controversial due to von Neumann's failure to name other contributors.

Reversing the AMD Secure Processor (PSP) - Part 2: Cryptographic Co-Processor (CCP)
Part one: https://dayzerosec.com/blog/2023/04/17/reversing-the-amd-secure-processor-psp.html
This is a follow-up part 2 to my previous post on the AMD Secure Processor (formerly known as the Platform Security Processor or "PSP"). In that post, I mentioned that the Cryptographic Co-Processor (CCP) is an essential component of how the PSP functions. It's primarily responsible for hardware-accelerated cryptography, but it's also used as a Direct Memory Access (DMA) copy engine for doing mass copy
gRPC-Gateway servers on AWS Lambda using Unix domain sockets
I’ve really enjoyed using gRPC-Gateway to build gRPC/JSON-over-HTTP (RESTful) APIs in Go for quite a few years now. However, at first glance, itappears to be...
The Architecture of Network-Aware Domain Name System (DNS)
This document describes a framework which extends the Domain Name System (DNS) to provide network awareness to applications. The framework enables DNS system responses that are dependent on communication service requirements such as QoS or path without changes in the format of DNS protocol messages or application program interfaces (APIs). The different enhancement methods and use cases are discussed.

No more outdated documentation!
And history of changes is your version control system.
LikeC4 provides:
architecture-as-a-code with native IDE support
development server with live reload
static website generation (live demo)
React and Webcomponents generation to embed to your website
CI/CD automation via CLI and GitHub Actions
export to various formats:
PNG
Mermaid
D2
DOT (Graphviz)
You can use LikeC4 standalone or integrate with existing toolchain.
