Our show is all about heroes making great strides in technology. But in InfoSec, not every hero expects to ride off into the sunset. In our series finale, we tackle vulnerability scans, how sharing information can be a powerful tool against cyber crime, and why it?s more important than ever for cybersecurity to have more people, more eyes, and more voices, in the fight.

Wietse Venema gives us the story of SATAN, and how it didn?t destroy the world as expected. Maitreyi Sistla tells us how representation helps coders build things that work for everyone. And Mary Chaney shines a light on how hiring for a new generation can prepare us for a bold and brighter future.

What began as a supposed accounting error landed Cliff Stoll in the midst of database intrusions, government organizations, and the beginnings of a newer threat?cyber-espionage. This led the eclectic astronomer-cum-systems administrator to create what we know today as intrusion detection. And it all began at a time when people didn?t understand the importance of cybersecurity. 

This is a story that many in the infosec community have already heard, but the lessons from Stoll?s journey are still relevant. Katie Hafner gives us the background on this unbelievable story. Richard Bejtlich outlines the ?honey pot? that finally cracked open the international case. And Don Cavender discusses the impact of Stoll?s work, and how it has inspired generations of security professionals.

It?s a strange situation when someone can hold something hostage from halfway around the world. It?s tragic when your own pictures and files are remotely encrypted. But when it?s a hospital?s system? Ransomware becomes a problem about life or death. 

Eddy Willems recounts his involvement in defeating an early ransomware attack that targeted AIDS researchers. At the time, there was a way to discover the encryption key. But as Moti Yung warned, asymmetric encryption would change everything. In the years since, ransomware attacks have become much more popular?thanks in part to the rise of cryptocurrencies. While criminals think it?s an anonymous way to collect payment, Sheila Warren tells us that the opposite is actually true.

All communication leaves the possibility for crossed wires. And as we become more connected, there?s a chance for those with ill intentions to steal our information and meddle in our daily lives?with devastating results. 

Smriti Bhatt breaks down the complexity behind machine-in-the-middle attacks. Johannes Ullrich tells us why we shouldn?t always trust that free WiFi. And the ?father of SSL? Taher Elgamal notes that while cryptography can address the increasingly sophisticated nature of malware, there are no safe bets in security.

Overwhelming numbers are scary?even in the best of circumstances. You can plan for them, build up your defenses, and do everything imaginable to prepare. But when that horde of zombies hits, their sheer numbers can still cause devastation. 

Botnets are digital zombie hordes. Jamie Tomasello recounts the scale of the Bredolab botnet?and the many malicious kinds of missions it carried out. Martijn Grooten explains how botnets work, and why they can be so difficult to permanently dismantle. And Darren Mott shares some of the successes the FBI had in rounding up some of the world?s most prolific bot herders.

Logic bombs rarely have warning sounds. The victims mostly don?t know to expect one. And even when a logic bomb is discovered before it?s triggered, there isn?t always enough time to defuse it. But there are ways to stop them in time. 

Paul Ducklin recounts the race to defuse the CIH logic bomb?and the horrible realization of how widespread it was. Costin Raiu explains how logic bombs get planted, and all the different kinds of damage they can do. And Manuel Egele shares some strategies for detecting logic bombs before their conditions are met.

Sometimes a fun game, a friendly email, or an innocuous link can be the most convenient place for an enemy to hide. And its prey is none the wiser?until it strikes. The trojan horse uses many layers of deception to do damage. The ingenuity of these attacks keeps an alarming pace with the technology we use every day. But as long as we stick to trusted sites and sources, we can better the odds against those who use our trusting nature against us. 

Steve Weisman tells us about how trojans still keep security professionals on the defensive. Josephine Wolff details how these attacks have evolved, and keep evolving, to catch victims off guard. And Yanick Franantonio takes on the new frontier for trojan attacks.

Computer viruses and worms haunt the internet. They worm their way into a system, replicate, and spread again. It?s a simple process?with devastating consequences. But there?s a whole industry of people that rose up to fight back. 

Craig Schmugar recalls how he and his team responded to MyDoom, one of the fastest-spreading worms ever. Dr. Nur Zincir-Heywood reveals the inner workings of viruses and worms, and how they draw their names from the world of biology. And security expert Mikko Hypponen shares advice on avoiding malware. But he also warns that we?re in an arms race against malware developers.

When a robot goes bad, who is responsible? It?s not always clear if the user or the manufacturer is liable when a robot leaves the lot. Human behavior can be complex?and often contradictory. Asking machines to interpret that behavior is quite the task. Will it one day be possible for a robot to have its own sense of right and wrong? And barring robots acting of their own accord, whose job is it to make sure their actions can?t be hijacked? 

AJung Moon explains the ethical ramifications of robot AI. Ryan Gariepy talks about the levels of responsibility in robotic manufacturing. Stefanie Tellex highlights security vulnerabilities (and scares us, just a little). Brian Gerkey of Open Robotics discusses reaching the high bar of safety needed to deploy robots. And Brian Christian explores the multi-disciplinary ways humans can impart behavior norms to robots.

HitchBOT was an experiment in stewardship: A small, rudimentary robot unable to move on its own, depending on the kindness of passersby to help it along its journey. Until it met an untimely end. Trust is a two-way street, and because robots are not powered by their own moral code, they rely on humans to supply both empathy and support. 

Dr. Frauke Zeller shares HitchBOT?s origin story. Eli Schwartz recounts his heartbreak upon learning what happened in Philadelphia. Dr. Julie Carpenter analyzes why it all went down. And Georgia Guthrie epitomizes the outpouring of sympathy that followed. Together, they tell a layered story about humans, and how we respond to robots. With HitchBOT, we find a little hope in the shadow of its demise.

For years, prosthetic technology focused on form over function, on masking lost limbs, rather than agency and usability. But things are changing. Innovations in robotics are giving more people more options, with lower thresholds of entry?and lower price tags, too. 

Tilly Lockey takes us through her journey with prosthetic arms. Brian Schulz gives some history of mechanical prosthetics, and what it means for people to reach embodiment with their devices. Tyler Hayes talks about the software that made advancements in assistive technology possible. Charlie Kemp discusses his work building universal robot interfaces, and how they can benefit everyone. And Henry and Jane Evans explain how robots can help a person reach beyond their body?s limitations.

Who says tech talk has to be boring? On Compiler, we dig into tech topics big, small, and strange. We talk to people who know the code, and bring their perspectives back to you. Intrigued? Here's a preview episode.

Software development teams often reach a crossroads. Should they perform maintenance and address bug issues, or add new features to satisfy users? The former isn?t as exciting, but sometimes the most important work is invisible to those who reap the benefits. For now, the project has been released, and everyone wants to celebrate. But there?s an elephant in the room, one that teams can ignore?at least, for a while. In this episode of Compiler, we unpack the concept of technical debt, and wonder if there is a world where it doesn?t exist.

It?s hard enough to make a functional, reliable robot. Many people also want to make those robots in our image. That?s a tough needle to thread. Often, the most efficient design isn?t the most human-like one. But that isn?t stopping us from reaching for those humanoid robots. 

Professor Shigeki Sugano argues in favor of creating human-shaped robots. But it?s such an enduring challenge, we?ve come up with a name for it: the uncanny valley. Evan Ackerman walks us through the uncanny valley?s treacherous terrain. Deanna Dezern shares how she?s connected to her robot companion. And Dor Skuler explains how he deliberately avoided making his robots look like humans.

One of the first functional robots appeared on TV in 1966. That?s earlier than some of us expect. The Unimate?s televised premiere sparked the world?s imagination. It represented a host of possibilities. Those possibilities, however, also implied a coming competition that would last for decades. 

Dag Spicer tells the story of the Unimate, the first industrial robot?and how little the American public trusted it. But that distrust wasn?t universal. Tomonori Sanada explains how the Unimate was received very differently in Japan. Joe Campbell describes the dangers of working alongside industrial robots. But he?s working to change that with cobots. And Paul Shoup shares how his company, employees, and customers are benefiting from cobots.

Building a physical robot isn?t cheap?even when it?s the final version. Designing a robot and testing it over and over again? That takes a lot of tries. And likely more than a few failures on the way to success. Luckily, simulation software is reducing the scrap heap?and bringing down the costs of building robots from the ground up. 

Kevin Knoedler shares how simulation software allows him to program and design robots from home. And even though he doesn?t have the budget or support of major research institutions like DARPA, his robots still end up winning major competitions. Evan Ackerman points out that winning those competitions takes a lot of skills. But amateurs have more ways than ever to get started with robotics. Louise Poubel explains how much time, energy, and money is saved with robot simulation software?and how it?s not just for the amateurs. And Dr. Timothy Chung reveals how competitions like the DARPA Subterranean Challenge encourage innovators to advance the field of robotics.

The 1980s promised robotic servants were in reach. They?d clean up our houses. Bring us drinks. Usher in an era of leisure. We didn?t get robot butlers. But if we look around, we?ll find an army of robotic servants already automating away domestic drudgery. 

Richard Rowland recounts the extent to which Androbot over-promised on its ability to build a robot servant. 40 years later, we still don?t have robot maids. Monroe Kennedy III walks us through the complexities of seemingly simple tasks. To make things more difficult, each attempt to build a robot had to build the hardware AND write the code from scratch. Keenan Wyrobek explains that?s why he helped write and share the Robot Operating System (ROS). Leila Takayama describes how beneficial ROS was to the field of robotics. And Terry Fong shares how NASA is using ROS to build the robots that explore our solar system.

The Y2K bug generated a lot of fear, but all that hype fizzled when the new millennium didn?t start with a digital apocalypse. It turns out that fear was just aimed at the wrong catastrophe. While plenty were riding high on the rise of the internet beyond the Y2K scare, another disaster had been brewing since 1995?and would bring them back down. But the dot-com bubble wasn?t the end. The internet was here to stay. 

Not long after the turn of the millennium, the dot-com economy collapsed. Peter Relan points to the flawed business plans that fueled the dot-com bubble, and how many entrepreneurs and investors underestimated the complexity of building a business on the internet. Ernie Smith tells the story of Pets.com, and how a similar idea a decade later had a much better chance of succeeding. Gennaro Coufano reveals the element of luck that saved Amazon from going under ?and how it evolved in the aftermath. Julia Furlan reflects on the changes the dot-com bubble brought, and what?s left to consider. And Brian McCullough describes how the dot-com bubble paved the way for a more resilient digital economy.

1995 laid the groundwork for a truly global World Wide Web. But not every country took the same path to connecting to the internet. Some resisted, wanting to create their own version. Others had to fight for access, not wanting to be left behind. And while we made huge strides in connecting the world in those early years, we still have a long way to go. 

Julien Mailland recounts the rollout of France?s Minitel service?how it was years ahead of the internet, but eventually lost its lead. Steve Goldstein explains what was involved in building the infrastructure to expand the NSFNET beyond the United States. Gianluigi Negro shares how China pushed for its connection, and how different it would be compared to the typical U.S. connection. And Christian O'Flaherty covers how costs weighed heavily on Argentina?s attempts to join the growing international network.

The web was growing quickly in the ?90s. But all that growth wasn?t going to lead to much if people couldn?t actually find any web sites. In 1995, an innovative new tool started crawling the web. And the search engine it fed opened the doors to the World Wide Web. 

Elizabeth Van Couvering describes trying to find websites before search engines, and how difficult it was becoming in the early ?90s to keep track of them all. Louis Monier talks about having to convince others how important search engines would become?and he showed them what a web crawler could do. Paul Cormier recounts taking the search engine from a research project to a commercial one. And Richard Seltzer wrote the book on search engines, helping the rest of the world see what a profoundly vital tool they would become.

We put a lot of trust into online shopping: sharing our names, addresses, and handing over money. In return, we have faith that the purchased item appears at our doorstep in a few days or weeks. That trust didn?t come easily. In 1995, we took our first steps out of the brick and mortar store to load our digital shopping cart. 

Robert Spector reveals how Amazon.com?s business foundations are in data?and being early to the internet. Sandeep Krishnamurthy recounts the rise of eBay. Angela Robinson describes the technology that makes secure transactions and trustworthy e-commerce possible. Kartik Shastri shares how difficult it was to store and process consumer data. And Katie Wilson explains how some big tech companies are different from previous monopolies, but are following many of the same paths.

Looking at the internet in 1995 is like looking back at awkward grade school yearbooks?all the weirdness and flaws stand out in stark contrast to what it?s grown into since. And web design took awhile to become a career?but it got a big boost in 1995. When the Batman Forever website launched to promote the movie, it showed people what was possible on the web. And it forever changed what we?d expect from a website. 

Jay Hoffmann describes the quirky designs of the early web. Richard Vijgen explains how we went from a lack of conventions to a homogenized web. Jeffrey Zeldman recounts building the Batman Forever movie?s website?and sowing the seeds of professional web design. Jessica Helfand outlines the process and joys of designing a web page. And Kyle Drake shares how he founded Neocities in an attempt to recreate some of that magic of the early web.

The Hypertext Markup Language (HTML) gave everyone a foundation for building and viewing the World Wide Web. In 1995, its standardization led to dominance. Its simplicity helped it spread. And its solid common foundation helped shape the internet. 

Dr. Belinda Barnet explains what kind of framework was initially needed to build and navigate the Web. Jeff Veen describes the three ingredients Tim Berners-Lee combined to create HTML: the ideal language for the Web. Gavin Nicol recounts the need to standardize the quickly-growing language. And Gretchen McCulloch points out how HTML instills an inherent bias for English speakers to develop for the web.

1995 was the year that ISPs became the dominant gateway to the information superhighway. But how?d we go from ARPANET all the way to that? It turns out, none of it would have happened without a team of intrepid engineers at the University of Michigan.

Marc Weber tells us how a tension between academics and the military set the next evolution of the ARPANET. Douglas Van Houweling discusses the work his MERIT team did at the University of Michigan to build the national backbone of the NSFNET. Elise Gerich, MERIT?s systems manager, talks about how they made the leap from a T1 connection to a T3 to handle traffic from their growing network. And Janet Abbate emphasizes how all this set the stage for the commercialized internet that birthed the dot-com boom in 1995.

The year is 1995. The internet starts going mainstream and the dot-com bubble begins its rapid inflation. But 10 years before all of this, a small team of systems administrators made a seemingly simple decision that would turn out to have a monumental impact on these events and would set the course of the internet for the foreseeable future. 

Dr. W. Joseph Campbell sets the stage for our season on the internet in 1995. Claire L. Evans explains how hard it was to find anything on the early internet. One team was charged with compiling that information in the early days of the ARPANET. Elizabeth ?Jake? Feinler recounts being the internet?s sole librarian in those early days, and how she helped come up with the rules for future domain names. Paul Mockapetris describes designing the domain name system they later implemented as the internet went from a public network to a private business. And Ben Tarnoff explains the results of that increasingly privatized internet.

The internet?s been around for awhile now. And it?s safe to say that it?s changed much of our daily lives. But not so long ago, there were few people who realized how transformative the internet would become. Season 7 of Command Line Heroes looks back at those few who saw the internet?s early potential and forever shaped it during its most formative year: 1995. 

From the origins of e-commerce, to web design, to HTML, to the infrastructure holding it all together around the world, this season highlights the heroes who turned the nascent internet into the vital global network we know today.

If you think hard work is enough to guarantee success, you haven?t been listening. All season long, we?ve profiled Black inventors who haven?t quite been given their due. Arlan Hamilton is helping reverse that trend by leveling the playing field?and changing the venture capital game.

Arlan Hamilton?s story mirrors many we?ve covered this season?overcoming adversity to find success. But she?s also helping redefine what success can look like and, in the process, is helping change the broader tech industry. Janice Omadeke lays out how diversifying the VC community in turn leads to greater diversity among founders receiving funding. Ramona Ortega explains how traditional VC priorities often pass over startups that can be successful. And Scott Myers-Lipton discusses inequality in Silicon Valley (and beyond) and how he?s working to bring about lasting change.

Is the moon made of cheese? Of course not. But can a person walk on the surface? Not too long ago, we couldn?t answer that question. But with the help of Gladys Perkins, we soon figured out that we could send a team to the moon and have them safely land on its surface. 

There was a time when the United States was behind the Soviets in the space race. Everyone had their sights set on the moon. Andrew Chaikin describes NASA?s disastrous Ranger missions. Erik Conway explains how complicated the trajectory calculations were?and to top it all off, why they often couldn?t be done in advance. To succeed, NASA?s new Surveyor program would need the capability to adjust trajectory mid-flight. Gladys Perkins made those calculations possible. But her part in this story hasn?t been well documented. Our editor Kim Huang recounts how difficult it was to get details of her story. And Vahe Peroomian explains how important it is to get these histories told to inspire the next generation to take on moonshot projects.

Finding information about Gladys Perkins was tough. We found some breadcrumbs to her story on this Hughes Aircraft blog.

Roy Clay had to chase after opportunities. But landing a promising position wasn?t the finish line. Roy Clay pushed those opportunities beyond their mandate, transforming an industry in the process.

Kathy Cotton recounts how few opportunities Roy Clay had growing up?but how, later, talk of his genius helped him get his break in the tech industry. Chuck House describes how Clay?s qualifications and experience were just what Hewlett and Packard were looking for. Bill Davidow explains how Clay made his mark at HP building a department, and shaping the strategy for a revolutionary 16-bit minicomputer. And in Clay, Ken Coleman found a role model and mentor. He followed in Clay?s footsteps, and helped expand a legacy of inclusion.

Chuck House interviewed Roy Clay for his blog.

It?s not easy to learn how to use computers when you can?t actually touch them. But that?s how Dr. Clarence Ellis started his career of invention?which would ultimately lead to reimagining how we all worked with computers and each other.

Martez Mott describes the ?Mother of all Demos? that would inspire a generation of builders. Gary Nutt recounts working with Dr. Clarence Ellis at Xerox PARC, and the atmosphere at the coveted research lab. Chengzheng Sun and Paul Curzon explain how Operational Transformation?the project to which Dr. Ellis devoted so much time and effort?laid the foundation for the collaborative tools many of us use every day. And Delilah DeMers shares how humble her father was, and how he loved teaching people that technology can be a force for good.

Sometimes an inventor designs a device for a specific purpose. Sometimes it?s to try something new. But successful inventions often shape industries beyond those they initially intended. Dr. Marc Hannah built an invention with far bigger effects than anyone could have imagined?like bringing dinosaurs to life, building liquid robots, and letting the Titanic set sail one more time. 

Raqi Syed gives some context on the evolution of special effects in the movie industry. Mark Grossman explains how the graphics world was more than ready for an upgrade. Tom Davis recounts the difficulties that he and his team had getting people to understand what was possible with the Geometry Engine. Luckily, Steve ?Spaz? Williams defied his bosses and showed them its power to bring worlds to life, starting with Jurassic Park. Camille Cellucci explains that from then on, everything changed for the movie industry?and for the broader world of graphics.

Dr. Mark Dean has a superpower. He wasn?t born with it. He wasn?t exposed to high levels of radiation. It?s a power he learned from his father. And because of it, he was able to revolutionize the personal computer. 

David Bradley explains how in the 1980s, IBM had a reputation for building big, enterprise mainframes. No one believed IBM could make a competitive PC. But that?s exactly what ?Project Chess? was tasked with creating. Tony Hey describes the monumental shift in strategy it was for IBM to enter the PC market. Pete Martinez and Dennis Moeller recount their days working with Mark on the skunkworks project. And how IBM's strategy for creating a computer in under a year changed the personal computing industry forever?opening it to innovators outside the walls of IBM. 

Mark Dean holds 3 of the 9 patents for the IBM 5150?the first IBM PC?including the revolutionary ISA bus. He then went on to lead the team that created the first gigahertz microprocessor, and eventually taught at the University of Tennessee. Mwamba Bowa shares her most cherished lesson from the inventor?how to cultivate that super power for herself.

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.

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.

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?

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.

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.

After four seasons of epic tales about how command line heroes have shaped the tech landscape, we're tackling a new topic: the job itself. 

 Season 5 covers the job of being a coder. How coding careers begin. How the job is done. How it?s changed. And how coders are shaping its evolution.

Clive Thompson, tech journalist and friend of the podcast, joins us for this 3-episode mini-season. Clive shares his insights from the over 200 interviews he?s conducted with coders: programmers, developers, software engineers, sysadmins, and more. The first episode drops July 14, 2020.

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.

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.

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.

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.

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.

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.

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.

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.
