The Thinking Machine by Steven Witt

The Thinking Machine: Jensen Huang, Nvidia, and the World's Most Coveted MicrochipThe Thinking Machine: Jensen Huang, Nvidia, and the World’s Most Coveted Microchip by Stephen Witt
My rating: 4 of 5 stars

Jensen Huang is a remarkable man. He is no doubt a very capable engineer, but his success has come more from his competitive drive and uncompromising work ethic. He both inspires and intimidates his followers. In that sense he is much like Steve Jobs, but Huang is smarter technically and shrewder in a business sense. He was always a big advocate of parallel computing. The current success of Nvidia, though, is partly luck. It began primarily as a graphics video card manufacturer relying mostly on PC gamers. It struggled along with that small consumer customer base until the killer app – AI – came along and found that the graphics cards were ideally suited for it. Huang was slow to see the match for what it was and much of the company’s success was due to the skill of some very smart people who were recruited by Huang for their brilliance and loyalty to parallel computing. They in turn were drawn to Nvidia because of Huang’s reputation as a parallel computing pioneer and because he had the hardware and openness to try new things. Nvidia is now the world’s most valuable company.

The book tells this story and tries to give the reader a sense of the technology, but is really a biography. There is a brief thumbnail description of a neural net and parallel computing, but barely mentions other aspects of artificial intelligence like Large Language Models (LLM), deep learning, or random forest computing. If you read this hoping to gain an understanding of how AI works, you will be disappointed. It seems many, maybe all, scientists and AI programmers don’t really understand how it works. The writing is professional, reportorial in style, but becomes rather repetitive largely because so many stories of the people who are drawn to Nvidia are so similar. If nothing else, I gained an appreciation for how complex and specialized the technology is and I learned that the huge energy draw AI causes is for the training, not as much its subsequent use. It’s not a page turner, but I enjoyed the book.

The Doorman by Chris Pavone

The DoormanThe Doorman by Chris Pavone
My rating: 4 of 5 stars

Chicky Diaz is the senior doorman at the most famous co-op/apartment building in New York City. He’s a loyal employee and all-around well-meaning soul who has come upon hard times. In the building are some fabulously rich residents including Emily, a drop-dead gorgeous raven-haired beauty married to Griffin, a despicable CEO of an arms manufacturer. Also in the building is Julian, a gallerist who makes a living selling ugly but valuable art to rich people like Emily and Griffin. Their lives intertwine throughout this novel. Some gangsters join the mix. The pace is good, the writing better, and the suspense builds. The author shreds Griffin and his MAGA brethren mercilessly, so if that’s your politics you won’t like this one, but that’s really a sidelight. There’s enough real action at the end to qualify it as a thriller, I suppose, but barely. It’s more about wealth inequality and the plight of the downtrodden.

The Last Ferry Out by Andrea Bartz

The Last Ferry OutThe Last Ferry Out by Andrea Bartz
My rating: 1 of 5 stars

This bait and switch is awful. It’s described as a twisty thriller and was on my library’s Mystery and Thriller list. There is no mystery and it’s not thrilling. It’s pretty much just a lesbian love story. Eszter (small pretty blonde) dies on a remote Mexican Island, and her fiancee Abby (tall muscular with a fade) goes there to find out what happened. Abby is paranoid and overreacts, misinterprets everything, and suspects everyone. Most of the book is spent talking about how beautiful Abby thinks Eszter was and their courtship and relationships with their parents and how much Eszter loved her muscles and height. I have no beef with lesbian love stories, I just don’t want to read one, especially when I’m expecting a mystery. It’s not even well-written and the title is misleading. I forced myself to finish it since I had nothing else handy – I’d read the last of my book club selections and all my holds at the library were taking forever to come in. One finally did. I’m going there now.

Confusing sign of the week

Right turn only but No right turn.

I think the Right turn only sign is for cars exiting the driveway and No right turns one for people wanting to enter. They’re at slightly different angles. I was probably making an illegal right turn into the parking lot as I got this photo. What adds to the confusion is the fact the driveway has a solid white line in the middle, suggesting that it is OK to turn in there. There is no Exit Only marking. That white line you see is the limit line for cars exiting but doesn’t extend all the way across, also suggesting the other lane is for entering cars.
