Today Quincy Larson interviews Justin Searls. He's a software engineer who cofounded a software agency 15 years ago that's still going – even after he figured out how to make a lot of money quickly and retire at age 38 once he had enough savings. These days he's gone from solving problems for client to solving solving problems for himself by building open source software. Often using emerging tools like agents. He says he getting way more done now than ever before. We talk about: - How software development is ceasing to be a team sport and is now more about individual devs working directly for the people paying them - How verifiability is everything - whether it's agents contributing to your codebase or humans - How someone just now entering the field can use emerging tools to get an edge over more experienced developers Note that I don't edit or censor these interviews at all.

This entire album features incredible drumming by Chic drummer Tony Thompson. And with Bass and Guitars by Duran Duran's John Taylor and Andy Taylor, the whole song has insane groove. 80s icon Robert Palmer sings and brings the texture. The guy reportedly smoked 60 cigarettes a day and paid the price a few years later, but man is his voice golden on this recording. Fun fact: Duran Duran's official site says they achieved the massive drum sound by putting mics at the top of a nearby elevator shaft. https://www.youtube.com/watch?v=Hw1t7OCESUw

I like the song feels slow and relaxed even though the tempo is really fast. It has really minimalist production - mainly just 808 drums and vocals. Perfect late night listening. https://www.youtube.com/watch?v=V6TEcoNUmc8

Over the holiday break I took my kids to Johnson Space Center in Houston. If you're in Houston you should absolutely go here. We visited the Mission Control center that NASA used during the Apollo missions to the moon. They also had an awesome multimedia experience created by Tom Hanks about this year's Artemis mission to the moon. This is an incredible museum. We spent 7 hours there. It wasn't particularly expensive. Just make sure you book tickets to mission control a few months in advance of your trip. 4. During the road trip, I re-listened to Guns 'n' Roses's entire catalogue. Which brings me to today's song of the week: the 1991 epic Estranged. The is maybe the most mature-sounding song they've ever done, with introspective lyrics and a series of tastful, emotional guitar solos. Great drum fills, too. https://www.youtube.com/watch?v=dpmAY059TTY
