On June 25th 2025, in collaboration with Open Folk, we presented our first ever live interview event in Los Angeles. As Open Folk put it: "In These Lines is a live event where three artists each bring one song — not just to perform, but to explore. They sit down with Sofia Loporcaro, host of Before The Chorus, to talk about where the song came from, what it meant to write it, and what it still holds. Then they play it. Just the song, and the truth behind it."

Before a song is released, a record is produced, or a chorus is written, the musicians that write them think. A lot. They live. A lot. And they feel. A LOT. Hosted by award-winning interviewer Sofia Loporcaro, Before the Chorus explores the genuine human experiences behind the music. Sofia’s deep knowledge of music and personal journey with mental health help her connect with artists on a meaningful level. This is a space where fans connect with artists, and listeners from all walks of life feel seen through the stories that shape the music we love. About the host: Sofia Loporcaro is an award-winning interviewer and radio host who’s spent over 8 years helping musicians share their stories. She’s hosted shows for Amazing Radio, and Transmission Roundhouse. Now on Before the Chorus, she’s had the chance to host guests like Glass Animals, Feist, Madison Cunningham, Mick Jenkins, & Ru Paul's Drag Race winner Shea Couleé. Learn more about your ad choices.

This episode I face my greatest fears: computer bugs. We are going to dive into the origin of the term, and examine the origins of debugging. The simple fact is that as soon as computers hit the scene we start finding bugs. Debugging follows very soon after. That part's not too surprising, it's the specifics that get interesting. Modern debugging methods we still use today were first developed on ENIAC, a machine that's anything but modern.

Episode 161 - The IAS Machine 1:03:18

לפני 13 ימים1:03:18

1:03:18

The first batch of digital computers emerge directly following WWII. The hallmark of this generation is uniqueness: no two computers are the same. However, there is a machine that bucks that trend. The IAS Machine, built in Princeton in the late 1940s, served as the inspiration for at least a dozen later computers. But how similar were these Princeton-class computers? What exactly was so special about the IAS Machine? And how does good 'ol Johnny von Neumann get tied up in all of this?

Episode 160 - What can Lunar Lander tell us about FOCAL? 56:28

56:28

Lunar Lander is one of the best loves video games of all time. The game was created in 1969 as an homage to the recent Apollo 11. From there it would only spread. Just about anything that can print text has it's own version of Lunar Lander. The early history of this game is mixed up with something weird: two nearly identical programming languages. Today we will be using the history of Lunar Lander as a good excuse to look at an obscure tongue called FOCAL. This language is so close to BASIC that direct line-by-line translation is possible. But are the two connected?…

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.…

Episode 158 - INTERCAL RIDES AGAIN - Restoring a Lost Compiler 1:08:22

לפני 8 weeks1:08:22

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 the early 1960s a neat little machine came out of MIT. Well, kind of MIT. The machine was called LINC. It was small, flexible, and designed to live in laboratories. Some have called it the first personal computer. But, is that true? Does it have some secret that will unseat my beloved LGP-30? And how does DEC fit into the picture?…

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?

In 1961 Texas Instruments unveiled the Molecular Electronic Computer, aka: Mol-E-Com. It was a machine that fit in the palm of your hand, but had all the power of a much larger computer. This was in an age of hefty machines, which made the achievement all the more marvelous. How was this even possible? It was all thanks to the wonders of molecular electronics, and a boat load of funding from the US Air Force.

It was made from scrounged parts, survived years of bombing raids, moved all around Berlin, and eventually took refuge in basements and stables. In this episode we will follow the Z4's early days, and look at how it fits into the larger picture of Zuse's work. Along the way there is looting, rumors, and even... IBM!

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.
