    From Apollo to Artemis: The Next Giant Leap

    On July 20, 1969, Apollo 11 landed on the Moon. And then, just a few years later, humanity stopped going. So what happened? Did we forget how to get there? Did the technology disappear? And if we could reach the Moon using 1960s technology, why did it take more than 50 years for humans to travel there again? In this episode of Mr. Fred’s Tech Talks, Mr. Fred connects the story of Apollo to the new era of Artemis. We explore why the infrastructure behind Apollo could not simply be restarted, how Artemis is building a new path back to the Moon, what Artemis II accomplished, why Artemis III is an important step even without a lunar landing, and how each mission builds toward what comes next. Along the way, Mr. Fred also reflects on another July 20 milestone—his birthday—and how both birthdays and space missions can remind us to look back, learn, and ask an important question: What are we going to do next? You’ll also hear connections to coding, engineering, experimentation, and the idea that progress often comes from taking what someone else built and carrying the mission forward. In this episodeWhy humans stopped traveling to the Moon after ApolloWhy returning was about more than simply rebuilding old rocketsHow Apollo and Artemis differWhat Artemis II accomplishedWhy Artemis III is a critical testing missionHow future Artemis missions could return astronauts to the lunar surfaceWhat Moon missions can teach kids about coding, engineering, and iterationMr. Fred’s July 20 birthday connectionA new Tech Challenge: Carry the Mission ForwardCallbacks and related contentLongtime listeners may remember Season 1, Episode 2, where Mr. Fred explored the technology behind Apollo 11.

    The Invisible Internet: What Happens When You Press Send?

    The fastest thing Mr. Fred has ever watched happen had no engine, no wheels, and no wings. In fact, he never actually saw it happen. He only pressed a button. In Season 2, Episode 21 of Mr. Fred’s Tech Talks, we follow the hidden journey that begins every time you send a message, open a webpage, stream a video, join a livestream, or ask an AI tool a question. What looks like one simple click sets an incredible process in motion. Information is broken into pieces, labeled, routed through a worldwide network, delivered to the correct destination, and reassembled, often in less time than it takes you to blink. In this episode, you’ll discover: • Why information travels in small pieces called packets • How IP addresses help data find the correct destination • How routers direct internet traffic from one stop to the next • Why DNS works like the internet’s phone book • How shared protocols allow different devices to communicate • Why the internet can often reroute around slowdowns and failures • How modern AI still depends on the invisible internet underneath it Mr. Fred explains it all with couches, pizza deliveries, phone books, traffic directors, struggling Wi-Fi, and blinking routers that are honestly doing their best. The internet is not magic. It is an amazing system built by people, and once kids understand that, they can begin to see themselves as builders, problem-solvers, and creators too. Tech Challenge: Trace Your Own RouteThis week’s challenge is to trace the path your data takes across the internet. On WindowsOpen Command Prompt and enter: tracert getmecoding.com On Mac or LinuxOpen Terminal and enter: traceroute getmecoding.com You will see a list of hops. Each hop represents another step your data takes on its way to the destination. Try running the command more than once. Compare the number of hops and response times to see whether the route changes. Parents and educators can ask young learners: • How many hops did the data make? • Which hop was the fastest? • Which one took the longest? • Did the route change when you tried it again? • What surprised you most? You do not need to understand every line. Curiosity is the win.

    From 1776 to the Lock Icon

    The American Revolution should not have worked. The British had professional soldiers, experienced commanders, better supplies, and the most powerful navy in the world. The Americans had courage, impossible odds, and something else that helped change history: secret communication. In this special 250th Fourth of July episode of Mr. Fred’s Tech Talks, we travel from Revolutionary War spycraft to the little lock icon on your browser. Mr. Fred explores George Washington’s spy network, the Culper Ring, invisible ink, coded numbers, Caesar ciphers, and how those early ideas connect to the encryption protecting your digital life today. You will learn what encryption is, why it matters, how plaintext becomes ciphertext, and why digital trust is about more than hiding information. It is also about knowing whether a message is private, authentic, and protected from being changed along the way. This episode also includes a hands-on Tech Challenge where listeners can create their own Caesar cipher message and experience the basic idea behind secret keys and coded communication.

    From Atari to AI, Part 3: The Doorway Moment

    Before Wi-Fi, smartphones, and AI tools that answer in seconds, getting online meant connecting a computer to a modem, plugging into a phone line, and hoping nobody picked up the phone in the other room. In this episode of Mr. Fred’s Tech Talks, Mr. Fred continues the From Atari to AI series with Part III: The Doorway Moment. This time, the story moves from the Timex Sinclair to the Christmas gift that changed everything: the Commodore 64. From there, Mr. Fred shares what it was like to connect through a modem, explore CompuServe, deal with the limits of dial-up, head to college with an IBM PS/2 Model 25, and later discover how digital communication changed the workplace during active duty in the Marine Corps. Along the way, we pause to explain what a modem actually did, why dial-up made those strange sounds, and how the movie WarGames gave many people a memorable picture of computers talking over phone lines. But this episode is not just nostalgia. It is a bridge to today’s AI moment. Just like dial-up once made computers feel connected to something bigger, AI now feels like another doorway. It is faster, more powerful, and a little unnerving. But the lesson remains the same: tools can help us, but humans still own the judgment, responsibility, and final decision. In This EpisodeMr. Fred explores: How the Commodore 64 became a major step beyond the Timex SinclairWhat a modem is and why it converted digital data to analog signals and back againHow dial-up, CompuServe, and phone lines shaped early online experiencesWhy early technology was exciting, limited, and sometimes boringWhat college computing looked like with an IBM PS/2 Model 25 and computer labsHow active duty introduced lessons about spreadsheets, email, reach, and responsibilityWhy AI feels like another “doorway moment”What parents, students, and teachers can learn from earlier technology shifts If this episode brought back a memory of dial-up, CompuServe, early email, computer labs, or someone yelling for you to get off the phone line, share it with someone who remembers that era too.

    From Atari to AI, Part 2: Programming the Machine

    In Part 1 of From Atari to AI, we talked about Atari, arcades, joysticks, cartridges, and the magic of playing the game. But in Part 2, something changes. This episode is about the moment technology stopped being something we only played with and became something we could create with. Mr. Fred shares memories of learning to program on the Timex Sinclair 1000, receiving a BASIC programming book from one of his mother’s coworkers, building a text adventure game with a friend, saving code on cassette tapes, and later experiencing the Apple IIe in a high school computer science classroom. Along the way, we explore why that blinking cursor mattered so much. A game console said, “Here is the game. Play it.” A computer said, “Here is the machine. Tell it what to do.” That shift from player to maker is at the heart of this episode and at the heart of GetMeCoding. In this episode: The difference between playing a game and programming a machineWhy the blinking cursor felt like an invitationMemories of the Timex Sinclair 1000Learning BASIC from an old-school programming bookBuilding a text adventure game on Saturday morningsSaving code on cassette tapesThe Apple IIe and turtle graphics in high schoolWhy coding helps kids build confidence, patience, and problem-solving skillsThis week’s screen-free Tech Challenge: Be the Computer Whether you grew up with BASIC, Apple IIe, cassette tapes, or you are simply curious about how we got from early home computers to today’s AI tools, this episode is a fun look back at the moment many of us realized: Technology was not magic. It was something people made. And maybe we could make something too. Tech ChallengeBe the Computer One person acts as the programmer. The other person acts as the computer. The programmer gives step-by-step instructions for a simple task, such as drawing a square, walking across the room, stacking cups, or making a peanut butter and jelly sandwich. The computer can only do exactly what the programmer says. No guessing. No filling in the blanks. Then debug the instructions and try again. It is a fun, screen-free way to teach sequencing, precision, debugging, and computational thinking.

    From Atari to AI, Part 1: When Technology Came Home

    Before smartphones, apps, YouTube, and AI chatbots, there was a box connected to the family television, a joystick with one button, and a generation of kids discovering that technology was not just something you watched. It was something you controlled. In Part 1 of the From Atari to AI series, Mr. Fred goes back to the moment technology first came home. From saving quarters for Atari 2600 cartridges at Kmart to the glowing magic of mall arcades like Aladdin’s Castle, this episode explores how early games and shared tech experiences sparked curiosity, pattern recognition, problem-solving, and a lifelong love of learning. This is not just nostalgia. It is the beginning of a bigger story about how kids move from playing with technology to wondering how it works — and eventually learning how to build with it. In this episode, Mr. Fred talks about: The Atari 2600 and how it changed the family living roomWhy early video games were simple but powerful learning experiencesThe social magic of arcades like Aladdin’s CastleHow games like Pac-Man and Galaga taught pattern recognition and strategyWhy every generation has a “gateway technology”How curiosity can move kids from consumers to creatorsThis week’s Tech Challenge: The First Tech Wow If you grew up with Atari, arcades, early video games, or simply want to help kids understand technology instead of just consume it, this episode is for you.

    Memorial Day Is Different: Remembering Those Who Never Came Home

    There is a funny thing we do with our phones. We back up everything. Photos. Videos. Contacts. Documents. Messages. Voice memos. The random screenshots we forgot we even took. But Memorial Day asks us to think about a different kind of memory. Not the kind stored in the cloud. The kind we carry. In this special Memorial Day episode of Mr. Fred’s Tech Talks, Mr. Fred takes a respectful pause to reflect on the meaning of the day. He explains the important difference between Armed Forces Day, Veterans Day, and Memorial Day, and why Memorial Day is specifically set aside to remember those who died while serving our country. As a former Marine officer and the father of an active duty Marine officer, Mr. Fred shares how service, sacrifice, and remembrance are deeply personal. This episode also brings in a meaningful technology connection. In an age where we can scan letters, preserve old photographs, digitize records, and share family stories across generations, technology gives us powerful tools to help preserve the legacy of the fallen. But technology cannot remember for us. It can store the data. It can preserve the record. But only we can preserve the meaning. This Memorial Day, may we pause, remember, and carry forward the stories of those who never came home. Episode Notes / BulletsIn this episode: The difference between Armed Forces Day, Veterans Day, and Memorial DayWhy Memorial Day is a solemn day of remembranceA personal reflection from Mr. Fred as a former Marine officer and military dadHow technology can help preserve military stories, photos, letters, and recordsWhy digital archives matter, but human memory matters moreA simple Memorial Day tech tip for families, students, and educators Tech TipUse technology this Memorial Day to remember someone specifically. Look up the story of someone from your town or region who gave their life in service. Search a local memorial. Scan an old photo. Preserve a letter. Record a family story. Help make sure their name and sacrifice are not forgotten. Call to ActionIf this episode helped you pause and remember, please consider sharing it with someone else who may need that same pause this Memorial Day.

    The Email That Got Me: Canvas, Phishing, and Social Engineering

    It was finals week. Students were trying to submit work, check grades, finish projects, and prepare for graduation. Then Canvas, the learning management system used by many schools and universities, became part of a major cybersecurity story. In this episode of Mr. Fred’s Tech Talks, Mr. Fred breaks down the recent Canvas breach and uses it as a teaching moment for students, parents, educators, and anyone who uses email, school platforms, or online accounts. But this episode is not just about hackers or software. It is about the human side of cybersecurity. Mr. Fred shares how students and faculty experienced the confusion in real time, how communication from schools and vendors mattered, and why stress, urgency, and uncertainty can make people more vulnerable to cyberattacks. He also shares something personal: during the same stressful environment, he fell for what appeared to be a phishing email that looked legitimate and seemed connected to a real student issue. That is the heart of this episode. Cybersecurity is not always a high-tech movie scene. Sometimes it is an email. Sometimes it is a nervous student. Sometimes it is a rushed decision. Sometimes it is realizing that even people who teach cybersecurity can get caught when the story feels believable. In this episode, you’ll learn: What happened with the Canvas cybersecurity incidentWhy social engineering is so effectiveHow phishing emails use urgency, trust, and timingWhy AI may make scam messages more convincingWhy we should avoid speculation while still understanding the risksWhat students, parents, teachers, and families can do to stay saferHow to use the “pause test” before clicking, entering a code, or approving a request This week’s Tech Challenge is the Social Engineering Audit: find one suspicious email, inspect it carefully, and look for signs of urgency, fear, curiosity, or pressure without clicking anything. If this episode helps you think differently about cybersecurity, share it with a student, parent, teacher, coworker, or anyone who has ever clicked something a little too fast. And as always: Keep learning. Keep questioning. And keep building.
