Episode 55 - Project Xanadu

Advent of Computing ·

2021/05/02

Project Xanadu, started in 1960, is perhaps the oldest hypertext system. It's creator, Ted Nelson, coined the term hypertext just to describe Xanadu. But it's not just a tool for linking data. Nelson's vision of hypertext is a lot more complicated than what we see in the modern world wide web. In his view, hypertext is a means to reshape the human experience. Today we are starting a dive into the strange connection between hypertext, networking, and digital utopianism. Like the show? Then why not

2021/04/18

Even after nearly 50 years C remains a force in the programming world. Anytime you brows the web, or even log into a computer, C is somewhere in the background. This episode I wrap up my series on C by looking at it's early development and spread. We will get into the 1st and 2nd C compilers ever written, and take a look at how a banned book lead to generations of avid C programmers. Like the show?

Episode 53 - C Level, Part I

Advent of Computing ·

2021/04/04

C is easily one of the most influential programming languages in the world, and it's also one of the most popular languages in the world. Even after close to 50 years it remains in widespread and sustained use. In this series we are going to look at how C was developed, how it spread, and why it remains so relevant. To do that we need to start with background, and look at what exactly influenced C. This episode we are diving into some more ALGOL, CPL, BCPL, and eventually B. Like the show? Then why

Episode 52 - THE SOURCE

Advent of Computing ·

2021/03/21

One of the great things about the modern Internet is the wide range of services and content available on it. You have news, email, games, even podcasts. And in each category you have a wide range of choices. This wide diversity makes the Internet so compelling and fun to explore. But what happens when you take away that freedom of choice? What would a network look like if there was only one news site, or one place to get eamil? Look no further than THE SOURCE. Formed in 1979 and marketed as the

Episode 51 - The IBM PC

Advent of Computing ·

2021/03/08

Released in August 1981, the IBM PC is perhaps one of the most important computers in history. It originated the basic architecture computers still use today, it flung the doors open to a thriving clone market, and created an ad-hoc set of standards. The heart of the operation, Intel's 8088, solidified the x86 architecture as the computing platform of the future. IBM accomplished this runaway success by breaking all their own rules, heavily leveraging 3rd party hardware and software, and by cutting

Episode 50 - 8086: The Unexpected Future

Advent of Computing ·

2021/02/22

The Intel 8086 may be the most important processor ever made. It's descendants are central to modern computing, while retaining an absurd level of backwards compatibility. For such an important chip it had an unexpected beginning. The 8086 was meant as a stopgap measure while Intel worked on bigger and better projects. This episode we are looking at how Intel was trying to modernize, how the 8086 fit into that larger plan, and it's pre-IBM life. Like the show? Then why not head over and support me

Episode 49 - Numeric Control and Digital Westerns

Advent of Computing ·

2021/02/08

Saga II was a program developed in 1960 that automatically wrote screenplays for TV westerns. Outwardly it looks like artificial intelligence, but that's not entirely accurate. Saga has much more in common with CNC software than AI. This episode we take a look at how the same technology that automated manufacturing found it's way into digital westerns, and how numerically controlled mills are remarkably similar to stage plays. Clips drawn from The Thinking Machine:

Episode 48 - Electric Ping-Pong

Advent of Computing ·

2021/01/25

Sometimes an idea is so good it keeps showing up. Electronic ping-pong games are one of those ideas. The game was independently invented at least twice, in 1958 and then in 1966. But, here's the thing, PONG didn't come around until the 70s. What were theses earlier tennis games? Did Atari steel the idea for their first hit?

Lars Brinkhoff has been spearheading the effort to keep the incompatible Timesharing System alive. Today we sit down to talk about the overall ITS restoration project, software preservation, and how emulation can help save the past. You can find the full restoration project at github: https://github.com/PDP-10/its And follow Lars on twitter: @larsbrinkhoff

Episode 47 - ITS: Open Computing

Advent of Computing ·

2021/01/11

Modern operating systems adhere to a pretty rigid formula. They all have users with password-protected accounts and secure files. They all have restrictions to keep programs from breaking stuff. That design has been common for a long time, but that doesn't make it the best solution. In the late 60s ITS, the Incompatible Timesharing System, was developed as a more exciting alternative. ITS was built for hackers to play, there were no passwords, any anyone who could find ITS was welcome to log in

Episode 46 - Hacker Folklore

Advent of Computing ·

2020/12/28

Hacker hasn't always been used to describe dangerous computer experts will ill intent. More accurately it should be sued to describe those enamored with computers, programming, and trying to push machines to do interesting things. The values, ethics, morals, and practices around those people make up what's known as hacker culture. Today we are digging into the Jargon File, a compendium of all things hackish and hackable, to take a look at hacker culture through its folklore. Huge thanks to some

Episode 45 - Keeping Things BASIC

Advent of Computing ·

2020/12/14

BASIC is a strange language. During the early days of home computing it was everywhere you looked, pretty much every microcomputer in the 70s and early 80s ran BASIC. For a time it filled a niche almost perfectly, it was a useable language that anyone could learn. That didn't happen by accident. Today we are looking at the development of BASIC, how two mathematicians started a quest to expose more students to computers, and how their creation got away from them.

Episode 44 - ENIAC, Part II

Advent of Computing ·

2020/11/30

In 1946 John Eckert and John Mauchly left the Moore School, patented ENIAC, and founded a company. One of those discussions would have consequences that wouldn't be resolved until 1973. Today we close out our series on ENIAC with a look at the legal battle it spawned, and how it put ownership over the rights to basic digital technology on trial. Along the way we talk legal gobbledygook, conspiracy, and take a look at some of the earliest electronic computers. Like the show? Then why not head over

Episode 43 - ENIAC, Part I

2020/11/16

Completed in 1945, ENIAC was one of the first electronic digital computers. The machine was archaic, but highly influential. But it wasn't a totally new take on computing. Today we are taking a look at the slow birth of ENIAC, how analog computers started to fall apart, and how earlier ideas transitioned into the digital future. Like the show?

Episode 42 - IBM Gets Personal

Advent of Computing ·

2020/11/02

This episode is not about the IBM PC. In 1981 the Personal Computer would change the world. Really, it's hard to talk about home computing without diving into it. But I've always had an issue with the traditional story. The PC didn't come out of left field, IBM had actually been trying to make a home computer for years. In 1981 those efforts would pay off, but the PC wasn't revolutionary hardware for Big Blue, it was evolutionary. So today we are looking at that run up with SCAMP, the 5100, and the

Episode 41 - Return of Viruses: The Spread

Advent of Computing ·

2020/10/18

It's time to round out spook month with a return to one of last year's topics: the computer virus. Malicious code traveling over networks is actually a relatively new phenomenon, early viruses were much different. In this episode we examine ANIMAL and Elk Cloner, two early viruses that were meant as practical jokes and spread by hapless computer users. Along the way we will see cases of parallel evolution, name calling, and find out if there is any one origin to the word "virus". Like the show? Then

Spam emails are a fact of modern life. Who hasn't been sent annoying and sometimes cryptic messages from unidentified addresses? To understand where spam comes from we need to look at the origins of email itself. Email has had a long and strange history, so too have some of it's most dubious uses. Like the show?

2020/09/20

We've all played the Oregon Trail, but what do you know about it's origins? First developed as a mainframe program all the way back in 1971, the Oregon Trail was intended as an educational game first and foremost. In fact, it traces its linage to some of the first efforts to get computers into the classroom. Today we are following the trail back to it's source and seeing how the proper environment was built to create this classic game. You can play the 1975 version here:

Episode 38 - JOVIAL, the Evolution of Programming

2020/09/06

The creation of FORTRAN and early compilers set the stage to change computing forever. However, they were just the start of a much longer process. Just like a spoken language, programming languages have morphed and changed over time. Today we are looking at an interesting case of this slow evolution. JOVIAL was developed during the Cold War for use in the US Military, and it's been in constant small-scale use ever since. It's story gives us a wonderful insight into how programming language change

Is there a more iconic duo than the IBM PC and MS-DOS? Microsoft's Disk Operating System would be the final success that turned the company into what we know today. But here's a dirty little secret: DOS didn't start out at Microsoft. So how did Gates and Allen get hold of a winning program? Today we look at how Tim Paterson, an engineer at a long forgotten company, created the first x86 computer and the original version of DOS.
