34. Why Is AI Writing in Markdown? And What Happened to HTML?
17:56||Season 2, Ep. 34Have you noticed AI creating files ending in .md? What exactly is Markdown, and why is a formatting language from 2004 suddenly showing up in so many artificial intelligence tools?In this episode of Mr. Fred's Tech Talks, we're pulling back the curtain on Markdown, HTML, and the surprisingly simple ways computers organize information.We'll explore how Markdown compares with HTML, why AI assistants frequently use it, and how a few ordinary keyboard symbols can turn plain text into a structured document.And because this is GetMeCoding, we're not stopping at explanations. I'll walk you through a LEGO Space Mission example to show how Markdown works and how it can be converted into HTML.In this episode:What Markdown is and what .md files containHow Markdown differs from HTMLWhy Markdown is useful in AI workflowsHow to create headings, bold text, and listsWhy understanding AI-generated files builds digital confidenceThis Week's Tech Challenge: Make Your Mark!Ask an AI assistant to create a simple Markdown document. Then open it, find the formatting symbols, and make one change yourself.You don't need to become a programmer. You just need a little curiosity.Find the episode resources, demonstration examples, and Tech Challenge at GetMeCoding.com.Keep learning, keep tinkering, and keep asking why!Mr. Fred's Tech Talks | A GetMeCoding podcast

33. AI, Our Kids, and Why I Still Have Hope
16:18||Season 2, Ep. 33AI can do the assignment. But can the student?After speaking at the CIU AI Summit in Pennsylvania, Mr. Fred left with his concerns about AI and learning reinforced—and a renewed sense of hope.In this episode of Mr. Fred’s Tech Talks, he shares a real classroom moment involving a broken Python program, a frustrated student, and a different way to ask AI for help. He also reflects on a student who needed help understanding his directions and the question that made him reconsider his own approach.For parents, grandparents, and educators, these stories open a conversation about the habits young people carry from school into work. Can they understand the task, check the result, make thoughtful decisions about sharing information, and take responsibility for their work?This week’s Tech Challenge, “Think First, Ask AI Second,” offers three questions you can try together.• What do I already know?• What specifically do I need help understanding?• Can I explain or apply what I learned?Explore coding, creativity, and technology with Mr. Fred at GetMeCoding.com.https://www.getmecoding.com
32. The Scam That Knows Where You Have Been
16:59||Season 2, Ep. 32I had every intention of releasing this episode last week. Then the Momentum Workshop with Lou Mongello, a trip to Washington, D.C., for the Marine Corps Marathon, and everyday work and life rearranged the schedule.Those two trips also created the perfect opening for this cybersecurity conversation.A scammer may not need secret information to create a convincing message. A conference name, a travel destination, a race photo, or the name of someone you trust can become personalized bait.Add artificial intelligence, and targeted phishing messages can be created faster and with cleaner writing than ever before.In this episode, Mr. Fred explains the difference between phishing and spearphishing, why familiar details do not prove a message is genuine, and how to verify a suspicious request without following the path it gives you.You will also learn what to do if you already clicked and receive this week’s Breadcrumb Challenge.The goal is not to stop sharing meaningful moments. It is to make one small pause before a convincing message turns trust into a trap.Cybersecurity Awareness Month: https://www.staysafeonline.org/cybersecurity-awareness-monthPhishing guidance: https://www.staysafeonline.org/articles/phishingStrong password guidance: https://www.staysafeonline.org/articles/passwords
31. AI Can Do It for You. Should You Let It?
17:24||Season 2, Ep. 31An AI assistant that can organize your plans and handle tasks sounds pretty helpful. But when it asks for access to your email, calendar, or credit card, how much permission should you give it?This week on Mr. Fred’s Tech Talks, we explore AI assistants and agents in plain English. What’s the difference between suggesting something and actually doing it? How can an assistant work inside an account without seeing your password? And why doesn’t a hidden password mean your information is out of reach?With familiar examples and a little humor, Mr. Fred explains how to put these tools to work while keeping yourself involved in the decisions that matter. No computer science degree required.You’ll learn:How AI agents go beyond answering questions.Why account access matters as much as password protection.What to review before an assistant sends, changes, or buys something.How to start small and explore with your family.October is Cybersecurity Awareness Month, and GetMeCoding is proud to participate as a Cybersecurity Awareness Champion through the National Cybersecurity Alliance.This week’s Tech Challenge: Pick one task you’d like an AI helper to handle. Decide what information it would need and which actions should require your approval.Explore more at GetMeCoding.com.What would you hand over to an AI assistant, and what would you keep firmly in your own hands?

30. Code Girls: The Women Who Helped Break WWII Codes
16:22||Season 2, Ep. 30What happens when a classroom codebreaking challenge leads to a remarkable piece of history?Mr. Fred explores Code Girls by Liza Mundy, the story of American women whose secret work helped break German and Japanese codes during World War II. Meet teacher-turned-codebreaker Dot Braden and discover Genevieve Grotjan’s contribution to solving the Japanese diplomatic cipher known as PURPLE.Along the way, we make sense of encryption, connect wartime secrecy to everyday privacy, and celebrate the people behind the technology. It’s a conversation for parents, educators, history fans, and anyone who enjoys a good puzzle.This week’s Tech Challenge: create and decode a secret message with someone using a simple Caesar cipher. All you need is paper, a pencil, and a little curiosity.Read Mr. Fred’s Code Girls book review:https://www.getmecoding.com/book-review-code-girls/
29. Blocky to Beautiful: How Video Games Went From Pixels to Worlds
23:58||Season 2, Ep. 29How did video games go from a handful of colored blocks to worlds filled with realistic faces, reflections, shadows, and light?In this episode of Mr. Fred’s Tech Talks, we follow the evolution of video game graphics from early Atari-era pixels to sprites, 3D polygons, textures, GPUs, and ray tracing, all without turning this into a computer science lecture.Along the way, we discover something even more interesting: better technology doesn't automatically make a better game. Early game designers had very little memory and processing power, so every pixel mattered. Those limitations forced programmers and artists to become remarkably creative. Today, games like Minecraft and modern pixel-art titles can look blocky by choice rather than necessity.That leads to a bigger lesson for kids, parents, educators, and anyone who likes to build things:Constraints can create creativity.This Week's Tech Challenge: The 8-Bit ChallengeCreate an 8×8 grid that has just 64 squares and try to make a picture someone else can recognize. Use graph paper, LEGO bricks, colored pencils, sticky notes, or whatever you have nearby. Don't add more squares. The limitation is part of the challenge. Then show your creation to someone without telling them what it is.Can they figure it out? If not…debug it!In this episode:What a pixel actually isWhy early video games looked blockyHow sprites became 3D modelsWhat polygons and GPUs actually doHow textures and lighting create realismRay tracing explained simplyWhy Minecraft doesn't need to look realisticHow limitations can make designers more creativeThe 8-Bit Tech ChallengeWhat was the first video game that made you stop and think, “Wow…that looks amazing”?Come find me at GetMeCoding.com and tell me.Follow Mr. Fred's Tech Talks wherever you listen so the next episode shows up automatically, and share this one with somebody who remembers spending a few too many quarters at the arcade.
28. What’s Really Inside a QR Code?
18:11||Season 2, Ep. 28You probably scanned a QR code this week.Maybe it opened a restaurant menu, a ticket, a payment page, or a website. Point your phone at a strange collection of black-and-white squares and somehow it knows what to do.But how?In this episode of Mr. Fred’s Tech Talks, Mr. Fred pulls back the curtain on QR codes and explains what is actually happening when your phone scans one.You’ll discover why QR codes aren’t simply “website buttons,” what those three big squares in the corners are doing, why damaged QR codes can sometimes still work, and how error correction helps recover missing information.There’s also an important cybersecurity twist. A QR code can hide where a link is taking you, which means scammers can use fake codes to lead people toward fraudulent login or payment pages. No need to fear QR codes, but it is worth remembering one simple habit: pause and verify before you tap.Then try this episode’s Mr. Fred Tech Challenge: The QR Code Stress Test. Create a QR code, cover a small portion of it, scan it again, and keep experimenting until you discover how much damage it can handle.It’s a simple experiment involving data, coding, computer vision, error correction, cybersecurity, and a bunch of little squares.Learn more and explore additional technology activities at GetMeCoding.com.Follow GetMeCoding on Facebook, Instagram, LinkedIn, and YouTube.Keep learning.
