Why Is Windows Built Like This? | Shop Talk #81

Shop Talk #81 explores the strange engineering decisions that still shape modern Windows systems today.Dave and Glen dig into GUIDs, COM, APIs, the Windows Registry, backwards compatibility, CPU scheduling, interrupts, abstraction layers, and why software architecture often becomes far more complicated than users expect.The conversation expands into how old engineers approached system design, whether modern abstraction layers hide too much complexity, and why low-level computing knowledge still matters.This episode was built directly from viewer questions and comments. 00:00 - Hey I’m Dave02:46 - Did you ever have some of your code be part of an exploit?04:03 - Considering today’s sheer mass of driver stacks… How would you organize this with the benefit of hindsight?05:06 - You didnt tell us what format the binary UID was in?06:29 - How does a person even get through the maze of gate keepers that exest to even use a solution like you did?07:23 - Has your ESP32 idle monitor led to any optimizations to other code running on the ESP32?07:52 - Am I the only one here who never knew that GUID is pronounced gwid?09:01 - 1) What about the counterpart function, StringToIID()? 2) Out of curiosity, did you ever have any experience with SOM, and if so, what are your takes on SOM vs. COM?09:57 - Have you considered using a bitmask instead of the if with 4 potential checks?10:48 - Why didn’t Windows just use 128 bit ID’s that were interpreted as {uint32, uint32, uint32, uint32} ?12:01 - I am wondering would you be able to make content how to use/read C?12:58 - When are you getting a gang together to give us a proper and correct windows alternative?13:56 - Great stuff except for your misrepresentation of Morse code…14:56 - Why did it have to be Morse code?15:26 - How did the agent get the command in the first place ?18:22 - Might try initializing the array with hyphens, then unroll that loop.19:07 - Where can I get a mezmerizer?20:23 - Is it nibble, or is it nybble?20:46 - Did your optimized function produce uppercase or lowercase hex digits?21:12 - Are you saying you’re the reason why MS always historically represents UUIDs with capitals letters?21:29 - Would have you really get rid of sprintf instead of printf, since IIDtoString should have converted IID to a string instead of print the outcome to the console?21:57 - Can you do a video on COM?22:31 - Looking at your code my first thought was why is this even in a loop, why not just unroll it?23:13 - Couldn’t that function be written with zero branching instructions?23:39 - Were you guys over medicated or under supervised?25:38 - I’d bet all of your electronic toys are cheaper than a boat?26:37 - So are you saying that the guid is unique to each installation/computer since I heard you mention it tied to a mac address?27:16 - Didn’t Microsoft use target big-endian systems also?27:37 - This may be a silly question, but why do these things need to be converted to strings anyway?28:17 - For converting to hex, you index into an array?29:20 - I wonder if your significant little improvement was the one of the reasons Microsoft was able to succeed in the marketplace?29:32 - How do you actually quantify 100% faster? It now takes no time?29:46 - Maybe its a 35000RPM drive because they didn’t use a synchronous motor?30:14 - Next two topics logging and ntp. ?30:38 - When is the Dave’s Garage shirt with Memory is a sort of a compression algorithm with a sense of nostalgia! coming out?30:51 - You mean that Transcend wifi sd card lurking in my drawer wont work any more?31:05 - Canadian Tire Money?31:26 - What the H E double hockey sticks is Canadian Tire Money?31:51 - We’re letting the Americans know about Canadian Tire money now?33:30 - Why was I not already subscribed?

Why Old Tech Feels More Trustworthy | Shop Talk #80

Shop Talk #80 explores why old technology often feels more understandable — and sometimes more trustworthy — than the systems we use today. Dave and Glen dig into retro payphones, massive 1980s hard drives, cloud dependency, hardware ownership, restoration projects, and the strange comfort of machines that users could actually understand and repair themselves. The discussion eventually expands into bigger questions about modern software complexity, AI systems, security vulnerabilities, and whether we’re slowly losing visibility into the technology we rely on every day. This episode was built directly from viewer questions and comments.

Will AI Flood the World With Security Vulnerabilities? | Shop Talk EP 79

What happens when AI can find every vulnerability in software? This week on Shop Talk, Dave and Glen dig into the real-world implications of powerful new AI systems that can identify—and potentially exploit—security flaws across major platforms. Are we about to see a flood of CVEs? Should these tools be limited to reporting bugs instead of exploiting them? And what does this mean for open source, businesses, and the systems we rely on every day? We also revisit Windows Task Manager—why it sometimes feels misleading, what it’s actually showing you, and the deeper trade-offs between accuracy and usability in system tools. Finally, we explore whether scenarios like WarGames are any more realistic today—and whether modern systems are becoming too complex to fully understand or control. 00:00 - Hey I’m Dave 00:34 - Are we about to see a flood of security vulnerability announcements (CVE’s) coming from this? 01:25 - Are we mistaking better answers for better understanding? 03:13 - Are we losing the ability to understand systems we rely on? 05:37 - Am I the only educated person for which all of this looks like a cliff edge coming at society at 100mph? 07:15 - How does a model like Mythos find vulnerabilities in all major operating systems? 08:27 - What is your AI development stack and does it have an orchestration layer? 10:27 - Can a quantum computer do AI? 11:41 - So why did they program it to be able to find the vulnerabilities AND the ability to exploit them? 15:11 - Why sometimes the CPU usage shows ZERO while all system is freezed and not responding? 16:34 - Which number in Task Manager should we actually trust? 18:09 - Is there a story behind the “System Idle Process” and what’s it main purpose is? 19:35 - Why does using GetSystemTimes not show the same CPU usage as the task manager? 20:28 - How should professionals actually measure real system performance? 21:05 - Why not if cpu usage is over 100 set to 100%? 22:00 - Why has TM not been updated to work better with multiple cores and clock speeds? 22:11 - Is Task Manager lying or are we just misunderstanding what it shows? 24:36 - Should tools prioritize accuracy or usability? 24:56 - Would showing raw data actually help users or just confuse them more? 25:43 - Why not stay quiet about the danger and share the vulnerabilities with the companies that need to fix their bugs? 26:22 - Could a modern version of WarGames actually happen today? 26:43 - Could a single bug or exploit realistically trigger a major event? 27:40 - Is complexity now the biggest security vulnerability? 28:39 - Could automation escalate a situation faster than humans can respond? 29:49 - Are safeguards today actually preventing disasters or just delaying them? 30:17 - Is the biggest risk external attackers or internal system failure? 30:43 - How do you even test systems that you can’t afford to fail? 31:37 - Are we building systems we no longer fully understand? 32:08 - How many years did it take to get this Vaudeville act perfected, lol? 33:51 - Are you somehow more funny/relaxed than maybe few months ago? 34:47 - What breaks first: trust in software or trust in data? 35:30 - Outtakes and odd stuff…

AI Won’t Fix This (And Might Make It Worse) | Shop Talk #78

We’ve been told AI is going to fix everything—but is that actually true? In this episode of Shop Talk, Dave and Glen dig into viewer questions about where AI falls short, what it can’t fix, and why many of the problems in modern software aren’t going away anytime soon. From performance and system design to security risks and patching complexity, we explore the gap between what AI promises—and what it actually delivers. Shop Talk Episode 78 — viewer questions drive the show.

Will AI Fix This? (Why Software Keeps Getting Worse) | Shop Talk EP 77

Will AI fix modern software — or just make the same problems faster? In this episode of Shop Talk, Dave and Glen dig into a question that keeps coming up: if AI can write code, why does software still feel slow, bloated, and unreliable? From abstraction layers and performance tradeoffs to the reality of debugging versus generating code, this conversation breaks down what’s actually happening under the hood — and why better tools don’t always lead to better software. Topics include: • Why modern apps feel slower despite faster hardware • The hidden cost of abstraction layers • What AI is good at (and where it falls short) • Debugging vs writing code • Why software complexity keeps growing If you’ve ever wondered why your computer feels slower than it should — or whether AI is really the solution — this episode connects the dots. --- Shop Talk is where we answer your questions and go deeper into the ideas behind the videos. #ShopTalk #Software #AI #Programming #Tech
