Episode Description: Jessica B. Harris may have been born and raised in New York City, but she has Tennessee roots through her father and has spent much of her life split between homes in the Northeast and the South – specifically New Orleans. For more than fifty years, she has been a college professor, a writer, and a lecturer, and her many books have earned her a reputation as an authority on food of the African Diaspora, as well as a lifetime achievement award from the James Beard Foundation. A few years back, Netflix adapted her book, High on the Hog: A Culinary Journey from Africa to America , into a 4 part docuseries. And I’m very proud to say that she’s a longtime contributor to Southern Living with a regular column called The Welcome Table. This episode was recorded in the Southern Living Birmingham studios, and Sid and Jessica talked about her mother’s signature mac and cheese, the cast-iron skillet she’d be sure to save if ever her house were on fire, and her dear friend, the late New Orleans chef Leah Chase.

LIVE from VCF West 2024, my talk on edge notched cards!

Since this is a live recording from an auditorium the audio is a little boomy, so be warned. Actually, I'm pretty sure this is the same space that CHM uses for some of their oral histories.

What I have today is just the audio component. VCF will be posting a full video eventually, which I'll be sure to pass around.

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

13 روز پیش1:08:22

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. Get the source code for INTERCAL72 here: https://github.com/rottytooth/INTERCAL72/ Read the original INTERCAL manual: https://3e8.org/pub/intercal.pdf…

The S1 operating system can do it all! It can run on any computer, read any disk, and execute any software. It can be UNIX compatible, DOS compatible, and so, so much more! But... can S1 ship? Today we are talking about an operating system that sounds too good to be true. Is it another example of vaporware? Or is S1 really the world's most sophisticated operating system?…

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?…

When I was down at VCF SoCal I ran into a strange machine: the Keypact Micro-VIP. It's a terminal without a keyboard, covered in dials, with a speaker and a switch labeled "voice". This chance encounter with the unknown sent me down a wild path. It involved the creeping spread of computing, chicken feed, door to door life insurance salesmen, and at least one early hacker.…

This episode we are taking a trip back to UNIX world. We're looking at IDRIS, the first clone of UNIX. It was supposed to be highly compatible, but use no code from Bell Labs. IDRIS ran on everything from the Intel 8080 up to the IBM System/370. There was even a version that could run MS-DOS programs. Sound too good to be true? Well, that may be the case.

1:03:21

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.

The Z4, completed by Konrad Zuse in 1945, is a computer with a wild story. 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.
