Mary Alyce Stephens (Hacker News, Reddit, TidBITS Talk):

Mark Stephens, known to much of the world as Robert X. Cringely, passed away on October 3, 2026. He was 73.

Mark was a gifted writer, journalist, storyteller, husband, father, brother, and friend. To millions of readers and viewers, he was Robert X. Cringely, the witty and sometimes irreverent observer of the technology world. But to those of us fortunate enough to love him, he was simply Mark-and losing him leaves an emptiness that is difficult to put into words.

[…]

Writing as Robert X. Cringely, Mark became a distinctive voice in technology journalism. He had an unusual ability to understand not only technology but also the human beings behind it-the dreamers, inventors, entrepreneurs, eccentrics, and risk-takers who were changing the world. He could take a complicated subject and make it understandable, entertaining, funny, and deeply human.

Steven Sinofsky (via John Gruber):

Bob wrote “Accidental Empires” that chronicled SV and the tech industry of the PC era, 1970s-90s. It led to the highly regarded PBS series “Triumph of the Nerds” a definitive series of interviews of the era. Through that time he authored the “gossip” column” in InfoWorld on the latest goings on at OG PC companies. Everyone read it in print religiously.

The next day Bob and I went to Sun Microsystems. He and I sat in a room with Jonathan Schwartz (CEO) and Rich Greene (C-something-else) while they defended Java and gave me nasty looks wondering who the hell I was and why the hell I was even there. They seemed plenty interested in impressing Bob though. By the way, Dotnet didn’t squish Java but I did get a Sun t-shirt.

Margaret Hamilton, a profoundly influential computer scientist best known for leading the software engineering team at MIT’s Instrumentation Lab during NASA’s Apollo program, died on Sep. 30. She was 90.

A computing pioneer who authored over 130 publications, Hamilton helped to establish software engineering as a dedicated discipline.

Moments before the Eagle module was set to land on the lunar surface, the onboard computer raised the alarm. It had detected a 1202 error: The computer was overloaded due to a fault in a hardware switch, and it was possible the system would not be able to handle the complex landing procedure.

But Hamilton and her team had engineered priority-driven software, able to shut down unnecessary background tasks in order to prioritize mission-critical tasks. Houston trusted Hamilton’s software and allowed the mission to proceed, and two men walked on the moon for the first time.

The following is an excerpt from a textbook called Fluency With Information Technology: Skills, Concepts, & Capabilities, 7th Edition ISBN 0-13-444872-3

At the time of publishing, the Wikipedia page for Margaret Hamilton has an important quote about the origin of the term “software engineering”. I was moved by this and wanted to add it to my /quotes page, but needed to verify the source of the quote. I was bothered that the source came from an interview given for an out-of-print textbook that as far as I can tell is unavailable to legally obtain. The interview is also not published in later editions of the book.

Fortunately, I was able to find the complete interview and I am publishing that excerpt here under fair use doctrine for educational, archival, and personal informational purposes only.

The Computer History Museum has an article and a full oral history.

You’ve probably heard the famous story of how Lorenz kept a continuous simulation running on his LGP-30 computer, and of that fateful 1961 day when he realized that even small differences in starting values could lead to very different outcomes—a sensitivity to initial conditions that is a hallmark of chaos theory, along with strange attractors. You might not have known that it was Hamilton who was responsible for programming the LGP-30.

Computers were still a novelty at the time, and neither Lorenz nor Hamilton had any programming knowledge; they taught themselves. Per a 2019 Quanta article, Lorenz was amused by her unusual methods: For instance, she once bypassed the “clunky debugging process” by rolling the paper tape down the hallway and editing the binary code by hand with a pencil. “I’d poke holes for ones, and I’d cover up with Scotch tape the others,” she recalled.
