Let’s talk about adulting— actual adulting. Not just paying bills or keeping a houseplant alive, but the kind that involves emotional maturity, healthy boundaries, and conscious self-leadership. Because let’s be honest, most of us weren’t taught how to be fully functioning adults… and it shows. Joining us is Michelle Chalfant , licensed therapist turned holistic life coach, creator of The Adult Chair® model, and author of the new book The Adult Chair: Get Unstuck, Claim Your Power, and Transform Your Life . With millions reached through her podcast, coaching programs, and retreats, she’s here to walk us through the five pillars of being a healthy, grounded adult. Here’s the truth: being an adult isn’t about checking boxes or pretending you’re fine. It’s about owning your truth. Feeling your feelings. Practicing compassion without letting yourself off the hook. It’s about setting firm boundaries—with no need for justification—and recognizing that your triggers are not flaws, they’re clues. None of us were handed a guidebook for how to grow up emotionally. We inherited patterns from people who were figuring it out as they went. But what Michelle shares today is empowering: it’s never too late to unlearn what no longer serves you and become the adult you were meant to be. Whether you’re starting this work or knee-deep in your personal development era, this episode will meet you where you are—and help you move forward with clarity, self-trust, and strength.

A lot of the technology we associate with the modern day started on anachronistic machines. I'm not talking about mainframes, I'm talking older. Today we are looking at George Julius's Automatic Totalisator, an analog computer used to manage betting at horse tracks around the world. These were massively complex machines, some networked over 200 input terminals, and they did it all mechanically.

In 1982 Intel released the iAPX 286. It's was the first heir to the smash-hit 8086. But the 286 was developed before the IBM PC put an Intel chip on every desk. It's design isn't influence by the PC. Rather, it reaches further into the past. Today we are looking at the strange melding of old technology, new ideas, and compatibility that lead to the 286.…

1:08:22

In 1973 the world caught it's first glimpse of INTERCAL. It's a wild and wacky language, somewhere between comedy and cutting satire. But the compiler was never circulated. There would be later implementations, but that original compiler remained lost to time. That is, until now. This episode covers how the original source code was found, and my attempt to get it up and running.

How do you make a computer act less like a computer? It sounds like some kind of riddle, but in the early 1960s it was an actual problem. As IBM customers transitioned from tabulators to computers they ran into all sorts of practical issues. Programmers became a hot commodity. But how do you find a programmer in 1959? And how can you even afford such a luxury? Wouldn't it be better if you could just use your new computer as a tabulator? Well, with RPG, all that and more was possible.…

In 1970 a little language called BLISS emerged from Carnegie Mellon University. It was a systems language, meant for operating systems and compilers. It was designed, in part, as a response to Dijkstra's famous Go To Considered Harmful paper. It had no data types. It used the most bizzare form of the pointer I've ever seen. And it was a direct competitor to C. Sound interesting, yet?

Have you ever felt like a computer just refuses to work? Like a machine has a mind of it's own? In 1970 a hard drive at the National Farmers Union Corp. office decided to do just that. That year it started crashing for apparently no reason. It would take 2 years and 56 crashes to sort out the problem. The ultimate solution would leave more questions than answers. Was the hard drive haunted? Or was something else at play?

Have you ever formed a bad first impression? Way back when I formed a hasty impression of this language called TRAC. It's been called a proto-esoteric language, and for good reason. It's outlandish, complex, and confounding. But, after the urging of some listeners, I've decided to give TRAC a second look. What I've found is, perhaps, more confusing than I ever imagined. This episode we are looking at the wild history of TRAC, how it actually pioneered some good ideas, and why it feels so alien.

Many of the features and ideas found in modern languages have their roots in ALGOL. Despite that influence, ALGOL itself remains somewhat obscure. It never reached the highs of a C or LISP.

Episode 124 - The Full 360 1:03:31

לפני 1 year1:03:31

1:03:31

The release of the IBM System/360 represents a major milestone in the history of computing. In 1964 IBM announced the 360 as the first family of compatible computers. Users could choose a system that was just the right size for their needs, mix and match peripherals, and have no fear of future upgrades. If you started on a low-end 360 you could move up to a top of the line model and keep all your software! Something like this had never been done before. Such a watershed moment resulted in interesting cascading effects. In this episode we will look at the 360 itself. In the coming weeks we will be examining how it shaped and dominated the market, how it led to a federal antitrust suit, and how a mysterious series of clone computers survived in uncertain times.

Episode 123 - The Jupiter Ace 57:35

לפני 1 year57:35

57:35

Released in 1982, the Jupiter Ace is a fascinating little computer. It's hardware isn't much to write home about. It's just an 8-bit microcomputer very much in line with other systems of the era. Where it shines is it's software. In a period when most home computer ran some version of BASIC the Ace was using Forth. On the surface that might sound like a trivial difference, but that one deviation from the norm made all the difference in the world.

Tools are the most important programs in the world. Without quality tools it's impossible to write quality software. One of those most important of those tools, and the most hotly coveted, is the text editor. These programs offer us a window into the digital world. It's no wonder that programmers the world over basically live inside text editors. In this episode will discuss when exactly that digital window was opened. When did text editors first appear? What forms did they take?

Episode 121 - Arguments Against Programming 1:04:13

לפני 2 years1:04:13

1:04:13

Most accounts of the early history of programming languages all share something in common. They all have a sentence or two explaining how there was great resistance to these new languages, but eventually all programmers were won over. Progress was made, despite the forces of counterrevolutionaries. What you won't find in most histories are the actual arguments these counterrevolutionaries made. This episode we are looking at those arguments. I've tracked down a handful of papers that argue against digital progress. Are these truly cursed articles, or is there something to be learned from arguments against programming?

This episode we are looking at a ghost of bygone days: batch processing! Before fancy terminals peppered computer rooms, before there was a microcomputer on every desk, there was the batch. In this non-interactive form of computing a user could wait hours, days, or even weeks to get a chance at computer time. Machines were kept well away from programmers, guarded by digital clerics. Why did such an arrangement exist? And did it ultimately help the programmer?

I will admit, the title here is a bit of click bait. In the early 1950s a researcher named Nils Aall Barricelli started in on a bold project. His goal was to simulate evolution on a computer and, in doing so, create a perfect lab to study evolutionary processes. What he found was astonishing. Given a simple rule set these interesting patterns emerged. He called them symbioorganisms. Despite being simple numeric constructs, they exhibited many properties of living things. Did Barricelli create a digital form of life? Selected Sources: https://sci-hub.se/10.1007/BF01556771 - Numerical Testing of Evolution Theories. Please, just read this paper and be amazed!…

In 1956 Librascope released the LGP-30, a truly wild machine. It was, for the time, the most simple and cheap machine that could actually be useful. It was the size of a desk when contemporary machines took up small rooms. It plugged into a normal wall outlet while other machines requires special power feeds. It was, perhaps, the first hint of a personal computer. And at its heart was a magnetic drum that only a true programmer could love.
