Drawing on experience building enterprise web agents, it explains why the demo succeeded and the deployment didn't, and what that means for choosing vendors, briefing the board, and avoiding mistakes others have already made.

The software would have cost $10,000, so the firm paid a middleman $40 an order to translate between its faxes and Federated's format. The standards had existed since the 1980s. For decades, whoever demanded the data got it, and whoever was asked paid for it. France's mandate, in force since September, hands that demand to the tax office, the one party every business answers to. ### Short Read - [The Quarter Nobody Collects]() — By [Sevda Polat]() · Published 2026-10-23 In a 1980s arcade, every cabinet had to earn its patch of floor. Arcade owners, by most recollections, wanted a quarter to buy two or three minutes of play. Anyone who lasted longer was occupying the machine for free. Switches inside many cabinets let owners set how many lives a coin bought. Atari founder Nolan Bushnell named the design this business needed: easy to learn, hard to master. ### Imagined Interview - [A Stopped Train Makes No Sound, So We Interviewed the Fireman Who Walks Through the Rain]() — Published 2026-10-23 *April 1911. The mess room of a Midland engine shed our guest asks us not to name, because "the company reads, and so does my mother." A kettle is losing an argument with a coal stove. Rain comes at the window sideways, as though it has a connection to make.* ### Paired Features - [Why Java Kept a Door to Nowhere]() — By [Sevda Polat]() · Published 2026-10-23 · Format: Paired Features Browsers stopped running Java applets between 2015 and 2017, and Java's maintainers tore out the machinery behind them in 2018. Yet the Applet API, the building blocks for writing applets, shipped with every copy of Java until March 2026. Other developers had built sound players and desktop panels on it, and removal waits for whoever is slowest to adapt. Meanwhile one applet-era idea from 1996, a file picker that grants access only to the file you choose, now sits behind the photo uploads people do every day. - [The Cookie Flaw Flagged in 1997 That Chrome Still Allows]() — By [Sevda Polat]() · Published 2026-10-23 · Format: Paired Features The 1997 rulebook for browser cookies already named the privacy problem. Third-party cookies let a company you never visited follow you across sites, so the rulebook said browsers should block them by default. Netscape and Microsoft shipped them switched on, and only years later did Safari and Firefox clamp down. Chrome, owned by an advertising giant, promised to follow, then backed away. A UK competition safeguard tied to that promise lapsed with it, over objections from all fifteen consultation respondents. ### Further Reading - **Conway's law, as Conway actually wrote it (1968)** — [Source]() — Published 2026-10-23 The original goes past the slogan: deciding how to staff a design team already settles design decisions. - **Jon Postel's robustness principle, in the 1980 TCP spec** — [Source]() — Published 2026-10-23 His "be liberal in what you accept" helped early networks interoperate and let sloppy implementations persist. The IETF reconsidered it in 2023. - **Ken Thompson's three-page case that reading the source isn't enough (1984)** — [Source]() — Published 2026-10-23 A Turing Award lecture about a compiler that hides its own backdoor. It reads differently now that machines write so much code. - **Fred Brooks sized up AI as a silver bullet in 1986** — [Source]() — Published 2026-10-23 He measured AI and "automatic programming" against software's hardest part, deciding what to build. That test still works on today's claims. - **The web began as a memo about CERN forgetting things (1989)** — [Source]() — Published 2026-10-23 Tim Berners-Lee blamed staff turnover for lost knowledge, and he planned for systems that start isolated and later merge. ### Past Articles - [Adopted but Unused, Used but Unadopted]() — By [Sable Whitford]() · Published 2026-10-16 · Format: After Adoption A Census Bureau survey of 117,000 businesses found AI adoption and AI use don't always travel together. Some firms formally adopted AI that workers aren't using. Some workers are using AI nobody approved. And 64% of AI-using firms reported making no institutional adjustments at all. Agent governance will have to handle both: maintaining what was formally built, and finding what grew on its own. - [The Six Thousand Rules]() — By [Sable Whitford]() · Published 2026-10-16 · Format: After Adoption DEC's expert system for configuring VAX orders worked: fewer than one misconfiguration per thousand. By 1987 it had 6,200 rules, half of them changing every year, and developers were copying rules whose rationale nobody remembered. A redesign effort couldn't outrun the growth. Agent deployments that succeed will pile up the same inventory of prompts, workarounds, and exception lists. The companion piece traces what's growing in the other direction. - [What robots.txt Was Never Asked to Carry]() — By [Sable Whitford]() · Published 2026-10-16 · Format: Historical Parallels In 1994, a web engineer proposed a two-field text file so site operators could ask crawlers to stay out of certain directories. It worked because everyone involved chose to go along with it. Thirty years later, publishers and regulators are trying to make that same file express commercial licensing terms, AI training restrictions, and limits on what agents can do. The convention hasn't failed. It's being asked to do work that needs identity, authorization, payment, and enforcement, none of which anybody built when the web was young, and the clearest view we have of those missing pieces is where the old file cracks. - [The Promise That Stopped at the Wire]() — By [Sable Whitford]() · Published 2026-10-08 · Format: Inside and Across Boundaries The first time an application has to coordinate work across two systems, the ACID guarantee hits a wall. Two-phase commit tried to push it across the network and buckled under real conditions. Sagas replaced it with something weaker and more honest: not rollback but compensation, new actions that approximate an undo without erasing anything. Agents inherit that world, calling APIs across boundaries that share no transaction manager. ## Other sections in Issue 52 - [Daily Brief]() - [Market Pulse]() - [Foundations]() - [Practitioner's Corner]() - [Vision]() ## More - [Publication guide]() - [Issue archive]()
