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.

Reminder: this season we’re building our very own, open source Command Line Heroes game. And you are invited to contribute—in whatever way makes sense for you. Visit Command Line Heroes: The Game over on GitHub for more info.

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.

In Season 2 of Command Line Heroes, we’re living on the command line, tracking the changes that shape the world of open source development. We’re discovering the origins of programming languages; mastering the art of making a pull request; learning about supercomputers, hybrid clouds, and more. Where does that lead us? Great heights and beyond.

Episode 1 launches September 11th. Listen for free on Apple Podcasts, Google Podcasts, or wherever you do your thing.

Imagine a world where open source never caught on, where no one thought it’d be a good idea to make source code available to anyone. In this episode, we imagine this bizarre possibility. And we celebrate the open source tools and methodologies that got us where we are today.

Join us as we wrap up Season 1, an almost 30,000-foot view of how the open source world came to be. Next season, we’re zooming in and focusing on the epic struggles of today’s command line heroes.

“There is no cloud. It's just someone else's computer.” Or server, to be exact. Big cloud providers offer a relatively easy way to scale out workloads. But what’s the real cost?

In this episode, we talk about the battle in the clouds, where any winner is still very much up in the air. Major Hayden, Microsoft’s Bridget Kromhout, and others help us understand the storm that’s brewing and where that leaves open source developers.

The rise of Container technologies opens a new frontier for developers, simplifying the movement of work from machine to machine. As Containers become more popular, though, a new battle emerges. This race is for the control of orchestration and involves the industry’s fastest, strongest players.

Containers are one of the most important evolutions in the open-source movement and in this episode, featured guests Kelsey Hightower, Google developer advocate, and Laura Frank, Docker Captain and Director of Engineering at Code Ship, along with others, explain how this new technology is the building blocks of the future.

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. Differences remain but with DevOps, teams are working better than ever. And this episode explores why that matters for the command line heroes of tomorrow.

It's the turn of the 21st century. Open source software is changing the tech landscape. But new patterns of work have now become necessary. Developers search for a revolutionary approach that will allow open source development to flourish. A group of developers convenes at a ski resort in Utah to craft such an approach. What emerges is a manifesto that changes everything.

Dave Thomas, one of the authors of the Manifesto for Agile Software Development, brings us back to that now famous retreat where the agile revolution was first organized. Not everyone was as quick to sign on to this new approach, though, and in this episode, we hear why.

It's the 1990s. The empire of Microsoft controls 90% of users. Complete standardization of operating systems seems assured. But an unlikely hero arises from amongst the band of open source rebels. Linus Torvalds—meek, bespectacled—releases his Linux O.S. free of charge. While Microsoft reels and regroups, the battleground shifts from personal computers to the Internet.

Acclaimed tech journalist Steven Vaughan-Nichols is joined by a team of veterans who relive the tech revolution that reimagined our future. Editor's Note: A previous version of this episode featured a short clip with Jon “maddog” Hall. It has been removed at his request.

The O.S. Wars. The 1980s is a period of mounting tensions. The empires of Bill Gates and Steve Jobs careen toward an inevitable battle over proprietary software—only one empire can emerge as the purveyor of a standard operating system for millions of users. Gates has formed a powerful alliance with IBM while Jobs tries to maintain the purity of his brand. Their struggle for dominance threatens to engulf the galaxy. Meanwhile, in distant lands, and unbeknownst to the Emperors, open source rebels have begun to gather…

Veterans from computer history, including Andy Hertzfeld, from the original Macintosh team, and acclaimed tech journalist Steven Levy, recount the moments of genius, and tragic flaws, that shaped our technology for decades to come.
