Stories about the people transforming technology from the command line up.

Episode Date
Dr. Gladys West: The Mathematician Who Reshaped Our World

Aristotle and Eratosthenes are big names in geodesy. They got pretty close to measuring the size of the Earth. But the woman who got it done? She grew up a farmer, dreaming of something bigger. And her work changed how we see the world.

Dr. Gladys West didn’t have much room for error in her quest for higher education. Marvin Jackson recounts the obstacles in her path—and the challenges she faced in her early career. Gavin Schrock traces how geodesy progressed before Dr. West, and how foundational her work was for the GPS systems that followed. Paul Ceruzzi describes the state-of-the-art technology available at Dahlgren that helped Dr. West model the world. Todd Humphreys explains how that model, and the GPS systems that use it, support our way of life in more ways than we realize.

It’s an astounding story that may never have been told if it hadn’t been for Gwen James, Dr. West’s Alpha Kappa Alpha Sorority sister. She makes the case for telling these stories before they’re lost—because there are definitely more of them out there.

Jerry Lawson: The Engineer Who Changed the Game

Many of us grew up playing cartridge-based games. But there's few who know the story behind how those cartridges came to be. And even fewer who know the story of the man behind them: Jerry Lawson. 

Few people realized how his vision would change video games. Jenny List explains how before Jerry Lawson, a console could only play one game. Benj Edwards describes how Lawson partnered with a pair of engineers to design a console with swappable cartridges. Pong creator Al Alcorn recounts the FCC limitations on Lawson’s Fairchild Channel F—and recognizes Lawson’s immense contributions to the gaming industry. And those in the know, like Jeremy Saucier, advocate for sharing Lawson’s story.

Because Lawson’s story was almost lost, he was recently recognized by Joseph Saulter at the Games Developer’s Conference—thanks to the work of journalist John William Templeton. And his children, Anderson and Karen Lawson, share how passionate Jerry was about electronics—and how much it meant that he finally got the recognition he deserved.

What Kind Of Coder Will You Become?

The 10x Coder is often positioned as a mythical developer who can always save the day. Saron and Clive investigate how much of that myth is grounded in truth. 

 Greg Sadetsky argues that coding is much like professional sports—some athletes are bound to be much better than those starting out. Brianna Wu and Bonnie Eisenman pick apart the myth by sharing how much they have had to clean up after supposed 10x Coders. Jonathan Solórzano-Hamilton recounts the story of "Rick," a self-proclaimed rockstar developer who assumed too much. And everyone considers the benefits of the 1x Coders—because what use is code without ideas and experiences to guide development?

Where Coders Code

Home office. Corporate park. Co-working space. Funland campus. Coders expect options when it comes to their workplace. The relocation of the average workspace from the office to the home has revealed the benefits of working from home—but also highlighted its tradeoffs. 

 Saron Yitbarek and Clive Thompson continue their discussion of coding careers by considering workspaces. Mary Allen Wilkes shares her experience as the first developer to work from home. David Heinemeier Hansson argues remote work gives his colleagues time for deep thinking. Dave West explains why he believes face-to-face work still produces the best results. And Maude Mensah Simpson weighs the freedoms of the home office against missing opportunities for in-person interactions.

Becoming a Coder

Command line heroes are software engineers, developers, programmers, systems administrators—coders. That variety in coding careers is almost as varied as the paths coders take to land their jobs. 

 Saron Yitbarek and Clive Thompson start the season by exploring some ways coders start their tech careers—some common, many unexpected. Many choose to start with a degree in computer science. But don’t underestimate the maturing bootcamp tracks, the mid-to-late-career switchers, and coders from outside the insulated tech hubs. You might be surprised who answers the call to code, where they come from—and how much they’ve already accomplished.

One More Thing with Steve Wozniak

Steve Wozniak (aka Woz) has had a tremendous effect on the world of hardware. Season 4 features many of the devices he’s designed, built, worked on, and been inspired by. But for Woz, what’s most important isn’t necessarily the devices he’s created—it’s how he built them. 

 Woz recounts how his early tinkering led to a lifelong passion for engineering. He started learning about computers on a GE 225 in high school. Soon enough, he was designing improvements to computers he wanted to buy—eventually defining his mantra for simplicity in design. That philosophy helped him finish the Apple I after seeing the Altair 8800 at the Homebrew Computer Club, and to create the floppy drive for the Apple II. But what he’s proudest of these days is the recognition for his engineering accomplishments—and sharing them with the world.

Consoles: The Dreamcast's Life After Death

Gaming consoles are pioneering machines. The Dreamcast pushed the limits of what even consoles could do. But that wasn’t enough to guarantee commercial success. Despite that failure, fans say no other console has accomplished so much. 

 The Dreamcast was meant to restore Sega to its glory days. After the disappointing Saturn, Sega pitted two teams against each other to build a new console. Andrew Borman describes the Dreamcast as a generational leap in hardware. Jeremy Parish explains how big a departure its production was from Sega’s usual processes. Mineko Okamura provides an insider’s insight on developing the Dreamcast. Brian Bacino recounts the console’s massive U.S. launch. But despite record U.S. sales, Sega had to pull the plug on the Dreamcast. Too good to let die, homebrewers like Luke Benstead plugged it back in.

Open Source Hardware: Makers Unite

People never stop tinkering. Hardware hacking didn’t disappear after personal computers became mainstream. But it did change. A new generation of artists, designers, and activists are banding together to change the world—with open source hardware. 

 Hardware hacking used to be expensive and time-consuming. Adaptable microcontrollers are making tinkering much easier. But even as the barriers to entry started falling, the practices around selling hardware have continued to veer toward secrecy. Ayah Bdeir, Alicia Gibb, and Limor Fried are working to keep hardware open. These leaders share how they helped build the open source hardware movement, and navigated fierce disagreements to make engineering accessible to all.

Smarter Phones: Journey to the Palm-Sized Computer

Few could imagine what a handheld computer would look like—or even do. But a trio of visionaries saw where computing was headed. To succeed in this new frontier, though, they would need to create everything from scratch, and throw out the conventional wisdom on hardware.

  Their creation, the PalmPilot, went on to break sales records. It showed the world what was possible and it helped people realize that the value in tech was shifting once again. But when the tech bubble burst and new competitors entered the market, Palm’s grip on the handheld computing industry began to slip.

Floppies: The Disks that Changed the World

The floppy disk was one of the greatest breakthroughs in computing. It helped spin up the software industry with a format that endured for decades. And in some cases, it’s conserved treasures once thought to be lost forever. 

 Before floppy disks came along, computing was weighed down by punch cards and magnetic tapes. Steven Vaughan-Nichols describes the magnitude of the changes brought by the floppy disk. Dave Bennet explains how the need for permanent storage, which was also easily mailable, led to the first 8-inch drives. George Sollman recalls how he was tasked with creating a smaller floppy, and what unexpected sources inspired the next design. And when Sollman showed it to the Homebrew Computer Club, a couple of this season’s usual suspects asked him to see more. And the rest is history. 

 Or is it? Matthew G. Kirschenbaum points out that floppy disks are still in use in some unexpected places. And Jason Scott and Tony Diaz tell us how they brought some source code from the sneakernet to the cloud.

Personal Computers: The Altair 8800 and the Dawn of a Revolution

The Altair 8800 is why we have computers in most homes today. It was initially designed for hobbyists. But a few visionaries saw massive potential in this strange little machine—and worked hard to make others see it too. What they created led to so much more than anyone could have ever imagined. Forrest Mims tells us how his co-founder, Ed Roberts, planned to save their struggling electronics company. His idea? A microcomputer made for hobbyists. That computer led to a fateful phone call from Bill Gates and Paul Allen. Dan Sokol and Lee Felsenstein recall the unveiling of the Altair 8800 at the Homebrew Computer Club, and how it sparked Steve Wozniak’s eureka moment for the Apple I. We then hear from John Markoff about an infamous software heist that set the stage for the debate about whether code should be proprietary. And finally, Limor Fried reflects on how this story continues to influence today’s open source hardware movement.

Mainframes: The GE 225 and the Birth of BASIC

The computing industry started booming after World War II. General Electric’s CEO refused to enter that market. But a small team of rebel employees bent the rules to forge on in secret. They created the GE 225. It was a giant leap in engineering that pushed computing from a niche market to the mainstream—sowing the seeds for today’s tech industry. Before the creation of general-purpose mainframes, computers were often built to perform a single function. William Ocasio recalls how GE’s first specialized computers, the ERMA, helped banks process thousands of transactions per day. John Joseph recounts how a few key GE employees hoodwinked their CEO into creating a computing department. Tomas Kellner explains how their work resulted in a revolutionary machine—the GE 225. And Joy Lisi Rankin describes how engineers at Dartmouth College adapted the GE 225 for time-sharing and used it to create BASIC—major milestones in making computing more accessible.

Minicomputers: The Soul of an Old Machine

They don’t fit in your pocket. But in their day, minicomputers were an order of magnitude smaller than the room-sized mainframes that preceded them. And they paved the way for the personal computers that could fit in a bag and, eventually, the phones in your pocket.

16-bit minicomputers changed the world of IT in the 1970s. They gave companies the opportunity for each engineer to have their own machines. But it wasn’t quite enough, not until the arrival of 32-bit versions.

Carl Alsing and Jim Guyer recount their work at Data General to create a revolutionary new 32-bit machine. But their now legendary work was done in secret. Codenamed “Eagle,” their machine was designed to compete with one being built by another team in their own company. These engineers recall the corporate politics and intrigue required to keep the project going—and how they turned restrictions into advantages. Neal Firth discusses life on an exciting-but-demanding project. One where the heroes worked together because they wanted to, without expectations of awards or fame. And all three discuss how this story was immortalized in the non-fiction engineering classic, The Soul of a New Machine by Tracy Kidder.

The C Change

C and UNIX are at the root of modern computing. Many of the languages we’ve covered this season are related to or at least influenced by C. But C and UNIX only happened because a few developers at Bell Labs created both as a skunkworks project. Bell Labs was a mid-twentieth century center for innovation. Jon Gertner describes it as an “idea factory.” One of their biggest projects in the 1960s was helping build a time-sharing operating system called Multics. Dr. Joy Lisi Rankin explains the hype around time-sharing at the time—it was described as potentially making computing accessible as a public utility. Large teams devoted years of effort to build Multics—and it wasn’t what they had hoped for. Bell Labs officially moved away from time-sharing in 1969. But as Andrew Tanenbaum recounts, a small team of heroes pushed on anyways. C and UNIX were the result. Little did they know how much their work would shape the course of technology.

That's all for Season 3. If you want to dive deeper into C and UNIX, you can check out all our bonus material over at You’ll find extra content for every episode.

Talking to Machines: LISP and the Origins of A.I.

Creating a machine that thinks may have seemed like science fiction in the 1950s. But John McCarthy decided to make it a reality. And he started with a language he called LISP. Colin Garvey describes how McCarthy created the first language for AI. Sam Williams covers how early interest in thinking machines spread from academia to the business world, and how—after certain projects didn’t deliver on their promises—a long AI winter eventually set in. Ulrich Drepper explains that the dreams of AI went beyond what the hardware could deliver at the time.

But hardware gets more powerful each and every day. Chris Nicholson points out that today’s machines have enough processing power to handle the resource requirements of AI—so much so that we’re in the middle of a revolutionary resurgence in AI research and development. Finally, Rachel Thomas identifies the languages of AI beyond LISP—evidence of the different kinds of tasks AI is now being prepared to do.

Heroes in a Bash Shell

Shells make large-scale IT possible. They’re a necessary component to modern computing. But it might not have turned out that way without a lot of hard work from a developer at the Free Software Foundation named Brian Fox. Now, the Bash shell is shipped with almost every computer in the world.

In the ‘70s, Bell Labs wanted to automate sequences of repetitive, complex commands. Chet Ramey describes how Bell developed several shells—but there could be only one officially supported shell for UNIX. Enter the Bourne shell. Though it was the best of that crop, the Bourne shell had its limits. And it was only available with a limited UNIX license. Brian J. Fox recounts his time at the Free Software Foundation where he needed to create a free—as in speech—version of the Bourne shell. It had to be compatible without using any elements of the original source code. That Bourne-Again Shell, aka Bash, is possibly the most widely used software in the planet. And Taz Brown describes how it’s one of the most important tools a developer can learn to use.

The Infrastructure Effect: COBOL and Go

Languages used for IT infrastructure don’t have expiration dates. COBOL’s been around for 60 years—and isn’t going anywhere anytime soon. We maintain billions of lines of classic code for mainframes. But we’re also building new infrastructures for the cloud in languages like Go.

COBOL was a giant leap for computers to make industries more efficient. Chris Short describes how learning COBOL was seen as a safe long-term bet. Sixty years later, there are billions of lines of COBOL code that can’t easily be replaced—and few specialists who know the language. Ritika Trikha explains that something must change: Either more people must learn COBOL, or the industries that rely on it have to update their codebase. Both choices are difficult. But the future isn’t being written in COBOL. Today’s IT infrastructure is built in the cloud—and a lot of it is written in Go. Carmen Hernández Andoh shares how Go’s designers wanted a language more suited for the cloud. And Kelsey Hightower points out that languages are typically hyper-focused for one task. But they’re increasingly open and flexible.

Diving for Perl

Languages come and go. A few have the right stuff to rise to the top—and fewer stay there. Perl had a spectacular rise, a quiet slump, and has now found its place in the world of programming.

Perl seemed destined to rule the web. Michael Stevenson and Mike Bursell describe how Perl’s design made it ideal for the early web. We hear from Conor Myhrvold about its motto: “There is more than one way to do it.” [Elizabeth Mattijsen](( shares how—despite Perl’s strength—a long development cycle slowed Perl’s growth. And although it’s not the top web language anymore, John Siracusa points out that Perl lives on as a niche tool.

Learning the BASICs

Becoming a programmer used to require a Ph.D. and having access to some serious hardware. Then, in 1965, a couple of engineers had a radical idea: make it easier for people to get started.

Beginner languages, like BASIC, burst the doors to coding wide open. Tom Cormen and Denise Dumas recall how BASIC changed everything. Avi Flombaum and Saron share tips on picking a first language in this new era of software development. And we hear from Femi Owolade-Coombes and Robyn Bergeron about how the next generation of coders are getting their start with video games.

Beginner languages give everyone an opportunity to get their foot in the door. And that helps the industry as a whole.

Python’s Tale
A benevolent dictator for life steps down and changes the course of the Python language forever. Guido van Rossum’s “Transfer of Power” memo brings attention to the way programming languages evolve. In this episode, Emily Morehouse makes the connection between Python’s technical extensibility and its inclusive community. Michael Kennedy explains how Python is both easy to learn and powerful enough to build YouTube and Instagram. And Diane Mueller highlights how the Python community took the lead on so many inclusive practices that are spreading in tech—including the rise of community-led decision-making. Sometimes, a benevolent dictator can get a language started. But Python shows it’s communities that make languages thrive.

At Your Serverless: Development Empowerment with Control
What does serverless really mean? Of course there are still servers—the basics of the internet aren’t changing. But what can developers accomplish when someone else handles the servers? Serverless computing makes it easy for beginners to deploy applications and makes work more efficient for the pros. Andrea Passwater shares how convenient it can be to abstract away (or remove from view) the infrastructure components of development. But as with any convenience, going serverless has tradeoffs. Rodric Rabbah explains that going serverless can mean giving up control of your deployment and restricts your ability to respond to problems—which is why he helped create Apache OpenWhisk, an open source serverless environment framework. And Himanshu Pant considers when to use serverless services. Serverless computing should be about developer empowerment. But we have to stay curious about the big picture—even as we simplify our toolbox.

The Data Explosion: Processing, Storage, and the Cloud
Big data is going to help solve big problems: how we grow food; how we deliver supplies to those in need; how we cure disease. But first, we need to figure out how to handle it. Modern life is filled with connected gadgets. We now produce more data in a day than we did over thousands of years. Kenneth Cukier explains how data has changed, and how it’s beginning to change us. Dr. Ellen Grant tells us how Boston Children’s Hospital is using open source software to transform mountains of data into individualized treatments. And Sage Weil shares how Ceph’s scalable and resilient cloud storage helps us manage the data flood. Gathering information is key to understanding the world around us. Big data is helping us expand our never-ending mission of discovery.

Fail Better: Embracing Failure
Failure is the heartbeat of discovery. We stumble a lot trying new things. The trick is to give up on failing fast. Instead, fail better. This episode looks at how tech embraces failure. Approaching failure with curiosity and openness is part of our process. Jennifer Petoff shares how Google has built a culture of learning and improvement from failure. With a shift in perspective, Jessica Rudder shows how embracing mistakes can lead to unexpected successes. And Jen Krieger explains how agile frameworks help us plan for failure. Failure doesn’t have to be the end. It can be a step to something greater.

Hello, World: Programming Languages for the Polyglot Developer
Every new programming language is created to do something previously impossible. Today, there are quite a few to choose from. But which ones do you really need to know? This episode dives into the history of programming languages. We recognize the genius of “Amazing Grace,” also known as Rear Admiral Grace Hopper. It’s thanks to her that developers don’t need a PhD in mathematics to write their programs in machine code. We’re joined by Carol Willing of Project Jupyter, former Director of the Python Software Foundation, and Clive Thompson, a contributor to The New York Times Magazine and Wired who’s writing a book about how programmers think.

Press Start: How Gaming Shapes Development
Before the terms 'open source' and 'internet' were even coined—there were gamers. They created proto-open source communities, sharing and building upon each other’s work. For many programmers, gaming led them to their careers. In this episode, we explore the creative free-for-all of early game development over ARPANET. Game development brings together a massive mix of creative and programming talent. But while creating video games started as an open process, a lot has changed. Hear how you can get involved in building our very own Command Line Heroes game—and in the spirit of games, hunt around for this episode’s Easter egg.

DevOps_Tear Down That Wall
As the race to deliver applications ramps up, the wall between development and operations comes crashing down. When it does, those on both sides learn to work together like never before. But what is DevOps, really? Developer guests, including Microsoft’s Scott Hanselman and Cindy Sridharan (better known as @copyconstruct) think about DevOps as a practice from their side of the wall, while members from various operations teams explain what they’ve been working to defend.
