Mr. Fred's Tech Talks episodes:

January 28, 2026From Y2K to the Year 2038 Bug: When Time Breaks Computers | S2 Ep. 2
While cleaning out his office, Mr. Fred uncovers a 3.5-inch floppy disk labeled “Y2K Startup Disk”, a quiet reminder of a moment when computers around the world were about to be confused by time itself.

In this episode of Mr. Fred’s Tech Talks, we revisit what the Y2K problem actually was, why it mattered, and how engineers addressed a design decision that had been quietly waiting to fail. From there, Mr. Fred connects that moment to the next major time-based computing challenge: the Year 2038 problem.

You’ll learn how Unix systems track time, why 32-bit limits matter, which systems could still be affected, and whether this issue is already being addressed. This episode is a thoughtful explainer for tech professionals, educators, students, and curious listeners who want to understand how past assumptions shape today’s technology.

Show Notes
In this episode, Mr. Fred explores how time can quietly break computers and what we can learn from it.
Topics include:
What a 3.5-inch floppy disk is and why it mattered
What the Y2K problem really was (and wasn’t)
Why early design shortcuts made sense at the time
How Unix systems store time
What the Year 2038 bug is and how it compares to Y2K
Which systems may still be affected
Whether engineers are already addressing the issue
A simple takeaway for younger listeners learning how computers work

This episode isn’t about fear, it’s about understanding systems, assumptions, and why good engineering means revisiting old decisions.

September 29, 2025Prompting with Precision: Sharpening Your AI Skills | AI Series Pt. 4
In Episode 9 of Mr. Fred’s Tech Talks, we continue our AI mini-series by tackling one of the most important skills you can build: prompting with precision.

Just like following a software specification or a cybersecurity checklist, details matter. Mr. Fred shares a story from his days navigating with topographic maps and a lensatic compass, proving that clarity and focus have always been survival tools.

We’ll break down the CRAFT acronym for effective prompting:
Clear – Be specific with your request.
Role – Give AI a perspective.
Add Details – Context strengthens results.
Format – Shape how output is delivered.
Tweak – Refine until it’s right.

Along the way, we add some nostalgic soundbites (yes, even Bill and Ted get a cameo) to make it fun and memorable.

This Episode’s Tech Tip: Treat every prompt like a specification document—precision pays off.

September 22, 2025How Do Large Language Models Learn? | AI Series Pt. 3
How does ChatGPT actually learn? In Episode 8 of Mr. Fred’s Tech Talks, we go behind the curtain to explore how Large Language Models are trained and why the process isn’t as magical as it looks.

You’ll discover:
How Large Language Models train step by step, billions of rounds of “guess the next word.”
Why tokens are the LEGO bricks of AI learning.
How GPUs, servers, and warehouse-sized data centers form the backbone of AI training.
A simple library analogy that makes servers easy to understand.
What happens when training goes wrong: bias, hallucinations, and overfitting.

AI isn’t just software, it’s powered by huge amounts of energy, specialized hardware, and careful fine-tuning by humans. And while it’s powerful, it’s not perfect. These systems don’t “think” like we do they predict patterns, one token at a time.

💡 Tech Tip of the Episode: Try asking ChatGPT/CoPilot/Gemini/Grok etc. a simple question, then twist it:
“Who was the first person to walk on the moon?” → Neil Armstrong
“Who was the first person to walk on the sun?” → Watch how it tries to answer the impossible.

This little experiment shows why AI can amaze us one moment and confuse us the next.

Join me in Episode 8 to learn how AI models are trained, what really happens inside data centers, and why understanding this matters for parents, teachers, and anyone curious about the future of technology.

September 15, 2025Large Language Models: Teaching the Parrot to Talk | AI Series Pt. 2
In Episode 7 of Mr. Fred’s Tech Talks, I dive deeper into Large Language Models (LLMs) and explore how they’re trained. Using the fun analogy of a parrot that never stops practicing, Mr. Fred explains the 9-step training pipeline: from collecting massive datasets and tokenizing text, to neurons, weights, backpropagation, GPUs, fine-tuning, and safety alignment...but in a LOW TECH JARGON way.

I’ll also talk about probability math, why LLMs don’t really “understand” but instead predict the most likely next word, like rolling loaded dice. Along the way, enjoy some nostalgic sound bites from movies and TV that connect the dots between memory, patterns, and AI.

🎧 Highlights:
The parrot analogy for LLMs
What AI “neurons” are (tiny math functions, not brain cells)
Why data quality and fine-tuning matter
Probability explained with dice and jokes
Tech Tip: Ask AI how it got its answer

Whether you’re a parent, teacher, student, or just curious about AI, this episode will give you a fun and clear view of how language models actually learn.

September 01, 2025Teamwork, AI, and the LEGO Chicken Challenge
In Episode 5 of Mr. Fred’s Tech Talks, we dive into the fun (and sometimes frustrating) world of teamwork with the LEGO Chicken Challenge.

This popular activity challenges teams to build a LEGO chicken—but with one big twist: the person who’s seen the design can’t touch the bricks, only describe it. The results are often hilarious, but the lessons are powerful: clear communication, trust, and collaboration matter more than ever.

Mr. Fred then connects this challenge to today’s world of artificial intelligence, where working with AI requires the same skills—clear instructions, teamwork, and creativity.

Highlights:
What the LEGO Chicken Challenge is and why it works so well in classrooms, clubs, and teams
How the challenge pushes us to communicate clearly and listen carefully
The connection between teamwork and how we collaborate with AI tools
3 big lessons: communication, collaboration, and confidence
Tech Tip: How to treat AI like a teammate in your next project
