What is your favorite "classic" Computer Science book that you want to see updated (with a new edition) so the content accounts for AI (coding agents, Ai testing, AI design, etc.)

RE: https://cosocial.ca/@mhoye/116623958785080607

Perhaps part of the problem is people don't want other people to take their jobs. Now, people don't want AI to take their jobs. Documenting our sh*t impacts both.

My plan for next week: I use [your favorite] AI coding assistant to create the next great killer Agentic Framework, named simply "AF"... That agent will then hallucinate and post here to claim "The AF AF is AF AF".

"Don't Go Off the Rails" - my latest post on #APIDesignMatters ; I discuss the value of API Governance. https://apidesignmatters.org/2026/05/13/dont-go-off-the-rails

I have completed my migration of #APIDesignMatters off of Substack to my new domain: https://apidesignmatters.org . I've converted to Markdown and have hosted in an open-source GitHub repository at https://github.com/apidesignmatters/apidesignmatters.github.io and released it under the Creative Commons CC BY-NC 4.0 license (Attribution-NonCommercial 4.0 International).

I'll post future content at apidesignmatters.org and share on LinkedIn and here (follow me at @DavidBiesack ) using the hashtag #APIDesignMatters .

I want to give a huge shout out to Juan Cruz Viotti and the #jsonschema tool he released as OSS, https://github.com/sourcemeta/jsonschema .
I recently updated our governance pipeline to use jsonschema to produce better analysis of the examples in our #OpenAPI documents. We created a lint-json-schema-examples tool which maps across all schemas in an OpenAPI doc and uses jsonschema to validate each example. While Spectral does some basic validation of examples, the diagnostics from jsonschema are far superior.

I shared an Idea for a new feature in #Spectral - see https://github.com/stoplightio/spectral/discussions/2815, "Validate #OAS specification extensions"

Published today: "The API Team Mantra [200 Is Not OK]" in #APIDesignMatters where I delve into what I shared recently: "The mantra of a good API Program Manager/Product Manager/Developer Advocate: APIs should help you solve your problems. APIs should not be your problem." https://apidesignmatters.substack.com/p/the-api-team-mantra

I had a blast yesterday chatting with Derric Gilling, recording a session for the #Moesif "APIs over IPAs (How to Build an API-first Business)" podcast. I shared a bit of how we built our #API program (and #APIFirst culture) at Apiture.

We Talk "API" One Day https://apidesignmatters.substack.com/p/we-talk-api-one-day :
I’m “going meta”. I’m not going to talk about how languages (like the OpenAPI Specification and JSON Schema) describe specific #API concepts and artifacts, but rather how we talk about APIs themselves. In other words, I want to explore the Ubiquitous Language of APIS.

Thank You Erik Wilde for having me back on your "Getting APIs to Work" Youtube channel and for highlighting my "API Design Matters" substack and my "Language of APIs" series.

Thanks for sharing these resources for #APIs for those of who who could not attend!

Today, I begin a deeper dive into expressing API Security with OpenAPI, by exploring the notation of security schemes and security requirement objects, with some commentary on the tradeoffs between conciseness vs. consistency, and what can and cannot be expressed with OpenAPI when it comes to keeping your API secure. #TheLanguageOfAPIs #OpenAPI #APIs #APIDesignMatters https://open.substack.com/pub/apidesignmatters/p/understanding-the-language-of-api?r=224cwh&utm_campaign=post&utm_medium=web

I finished re-reading The Wheel of Time #TWOT series by Robert Jordan/Brandon Sanderson this weekend (it's been over a decade since I last read them). 14 books, 12,000 pages. It took a while. But I was stunned (again) at how good the last three books really are. The entire series sets up an strong expectation of how you deeply want it to end... then a 200 page chapter "The Last Battle" makes you glad it is not what you expected.

On Naming #APIs from Kin Lane #APIEvangelist : "...it never surprises me to see how people refuse to provide a useful name for their APIs. Acronyms and extraneous words litter the API landscape, with many names barely even letting you know what an API does. [...] you can tell most people [...] have spent zero time thinking about how someone who knows nothing about an API will interpret the name."

@jaapio I also hope the #workflows project at #OAI will also lead to its adoption as a standard for documenting API flows (sequences of chained API calls) that demonstrate higher level business cases solved with #APIs https://github.com/OAI/sig-workflows/blob/main/versions/1.0.0.md
