Jack's Rants - Why You Need to Reboot : Why Rebooting Your Computer Actually Fixes Problems

Jack's Rants - Why You Need to Reboot : Why Rebooting Your Computer Actually Fixes Problems "Have you tried turning it off and on again ?" became an IT cliché for a reason. Rebooting clears accumulated state, resets resources, and fixes a surprising number of problems. From Unix uptime bragging rights to mainframe IPLs and Windows servers nobody is allowed to restart, every system has its own relationship with rebooting. Maybe what we really need is a reboot SLA.

Testing Software Properly : Software Testing Done Right – Where, When and What Should You Test?

Testing software sounds simple enough. But what exactly should you test, where should those tests happen, and how do you decide which parts of a complex system need the most attention? Jack talks with Mooly Beeri about software testing from a developer's perspective: identifying the right test points, understanding how different parts of a system interact, and building testing into the development process rather than treating it as something that happens at the end. A practical look at what it actually means to test software properly. You can read more from Mooly at https://www.bettersoftware.dev/ Want even more info ?

Microcode Mayhem : How a Mainframe Timer Bug Slowed an Entire Development Team

One day, a busy IBM-compatible mainframe began slowing to a crawl. Hundreds of programmers noticed immediately—some even resorted to banging on the server room window whenever the system became unusable. The problem appeared after a microcode upgrade, but nothing pointed to an obvious cause. In this episode, Jack Smith talks to Matt about an extraordinary piece of low-level troubleshooting that led deep into the internals of VM, interrupt handling and timer queues. Armed with nothing more than hex dumps, careful reasoning and a willingness to modify live memory, Matt uncovered a vendor bug and devised a temporary workaround that kept the system running until a permanent fix arrived. It's a fascinating story of how understanding a system at its lowest levels can solve problems that no diagnostic tool could explain. Want even more info ?

Jack's Rants - AI Is The New Shadow IT : Why Employees Are Quietly Building the Next IT Risk

Artificial intelligence didn't invent Shadow IT—it made it invisible. In this Jack's Rant, Jack Smith explores how AI tools like ChatGPT, Copilot and Claude have fundamentally changed the way employees solve problems. No servers under desks. No rogue software installations. Just a browser tab and a prompt. From confidential data and AI-generated scripts to fragmented workflows and "ChatGPT says..." becoming the new expert opinion, this episode examines why AI has lowered the barrier to creating business-critical systems outside IT's view. But this isn't a rant against AI. It's a reminder that Shadow IT has always been a symptom, not the disease. Employees don't create workarounds because they enjoy breaking policy—they do it because they're trying to get their jobs done. Instead of asking how to stop people from using AI, perhaps IT should be asking why they felt the need to use it in the first place. Because the organizations that succeed won't be the ones with the strictest AI policy, but the ones that make the secure, supported way the easiest way. Want even more info ?

Melbourne Cup Meltdown : How a Betting System Crashed at the Worst Possible Moment

Every year, the Melbourne Cup pushes Australia's betting infrastructure to its limits. In 1991, a known software bug turned one of the busiest days of the year into an IT disaster. As millions of bets poured in, CPU utilisation unexpectedly collapsed and the betting system ground to a halt at the worst possible moment. Jack Smith is joined by veteran mainframe specialist Neale to revisit the incident, explain why the bug had been accepted for so long, how the team recovered, and what modern IT professionals can learn about technical debt, capacity planning, and the risks of carrying known defects into critical production systems.

Jack's Rants - The Missing Five Minutes : Why scambaiting videos leave security professionals with more questions than answers

Scambaiters like Kitboga, Jim Browning and Pierogi educate millions, waste scammers' time, and undoubtedly prevent people from becoming victims. As a security professional, I genuinely appreciate what they do. But every time I watch one of these videos, I find myself asking the same question: What happened in the missing five minutes? How does a legitimate remote support session suddenly become full control over the scammer's computer? Is it a vulnerability? Poor operational security? Social engineering? Or simply the part of the story that gets left on the cutting room floor? This isn't a criticism of scambaiters. It's an exploration of the unanswered security questions that every IT professional should be asking, and why understanding how something happened can be just as important as enjoying the outcome.

One Network to Rule Them All : How a Missing VLAN Strategy Turned Smart City Infrastructure into a Cybersecurity Nightmare

Smart cities promise better transportation, connected infrastructure, and improved services—but what happens when everything is connected a little too well? In this episode, our guest shares the story of a security assessment in a major metropolitan smart city where network segmentation had been overlooked, creating unexpected paths between public networks and critical infrastructure. One memorable discovery showed that, with nothing more than the correct IP address, it was possible to operate a parking garage barrier from the city's public Wi-Fi while riding a bus on the opposite side of town. Together, we explore why VLANs and network segmentation remain some of the most fundamental principles in cybersecurity, how convenience can quietly undermine security, and why the smartest technology still depends on good architecture. It's a fascinating story that demonstrates how seemingly small design decisions can have city-wide consequences—and why "everything connected" should never mean "everything can talk to everything else."

Jack's Rants - Can I Keep Your ID? : Privacy, Identity Theft, Data Minimization, and Why Your Driver's License Is Not a Bar Tab Deposit

Opening a tab at a bowling alley shouldn't require handing over your driver's license or national ID card. Yet many businesses still ask customers to leave government-issued identity documents behind as collateral, often storing them in plain sight with little thought for privacy, physical security, or the risks involved. In this Rant, we ask a simple question: just because a practice has existed for years, does that make it acceptable? Want even more info ?

Cardboard Confidential : A Cybersecurity Incident, a Golf Course Conversation, and Why No Industry Is Too Boring to Be Targeted

No one expects a cybersecurity incident to begin in the cardboard industry. Yet as our guest Kayne McGladrey explains, cybercriminals don't care what your company manufactures—they care about opportunity. In this episode, Kayne shares how an unexpected conversation with a golf buddy led to a cybersecurity contract, and why one of the most unassuming industries turned out to have a story worth telling. Together, we explore the incident itself, how trust and professional networks can open doors in unexpected ways, and why manufacturing organizations of every kind have become attractive targets for cyberattacks. It's a fascinating reminder that behind every product—even a simple cardboard box—there's a complex IT infrastructure that deserves to be protected.

Jack's Rants - The New Change Management : ITIL Change Control, Organizational Change, and Why Project Managers Suddenly Need Psychology Degrees

Once upon a time, Change Management meant raising an RFC, preparing a rollback plan, and surviving the Change Advisory Board. Today, it also means stakeholder engagement, communication plans, adoption metrics, workshops, and apparently having the emotional intelligence of a licensed therapist Whether you're a project manager, systems engineer, change manager, or simply someone who's ever heard the phrase "we've always done it this way," this rant will probably feel uncomfortably familiar.

GDPR Enters the Chat : The Day a Hiring Exercise Became an Information Security Incident

It was supposed to be a routine hiring exercise. A candidate receives a technical assignment, reviews the provided material, and prepares a solution. Then someone notices that the "anonymous" dataset isn't anonymous at all. What follows is an uncomfortable discovery involving confidential business information, questions about data handling, and an unexpected conversation with legal. In this episode of IT Horror Stories with Jack Smith, we discuss how good intentions, poorly sanitized data, and assumptions about anonymity can quickly transform a recruitment exercise into an information security incident. Along the way, we explore data governance, confidentiality, risk management, and what organizations should do when they discover they've shared information they never intended to expose.

Spooling Out of Control : Enterprise Printing Explained and Why Printing Still Breaks IT

Printing is one of those technologies everyone assumes should have been solved years ago — until someone can't print invoices, shipping labels stop coming out, or 50,000 customer letters suddenly disappear into a print queue somewhere. In this episode, we take a tour through the strange and surprisingly complex world of printing: from small desktop printers and office multifunction devices to enterprise print servers and industrial mass-mailing environments that still move serious business. We explore why printing continues to survive every digital transformation, what actually happens behind the scenes when you click "Print," and why reliability suddenly becomes very important when paper turns into payroll, warehouse labels, customer communication, or operational downtime. Because nothing reminds people that IT exists faster than when the printer stops working. Want even more info ?

Sleep Mode in Production : How a Laptop Took Down a Warehouse

Welcome to the story of a perfectly known and visible laptop that somehow became critical production infrastructure inside a warehouse environment — without going through proper validation, testing, or operational review. The system worked, solved an immediate problem, and was quickly integrated into daily operations... right up until the laptop entered sleep mode and warehouse activities ground to a halt. What followed was a frantic investigation into why scanners stopped working, workflows froze, and logistics operations suddenly stalled because of a standard power-saving setting. It's a story about how quickly "temporary" operational solutions can become business-critical, and why governance, testing, and basic operational checks matter far more than people realize — especially when convenience quietly reaches production.

Ransomware Lockdown : What a Real-World Ransomware Attack Looks Like, Incident Response and Recovery

We explore a hypothetical ransomware scenario that mirrors what many organizations could face today. Imagine a normal day where systems suddenly become inaccessible, data is encrypted, and the scope of the attack starts to unfold in real time. What follows is a race against the clock, with teams trying to understand what's happening while keeping critical operations alive. More importantly, we focus on the response and recovery: the trade-offs, the communication challenges, and the lessons organizations can take away before something like this actually happens. Because ransomware isn't just a technical problem — it's an operational and human one, where preparation and clarity matter as much as the tools in place. Want even more info ?

Jack's Rants - Floppy Disks at 35000 Feet : Why Boeing 747s Still Use Floppy Disks for Flight Management Systems

The Boeing 747 is often cited online as proof that aviation still runs on floppy disks — but the reality is a bit more nuanced. In this Rant, we take a closer look at how certain older aircraft, particularly some 747-400 configurations, still use floppy disks to load navigation data into their Flight Management Systems. It's not about being outdated — it's about reliability, certification, and systems that have proven themselves over decades of operation. We also compare this against the wider IT world, where legacy systems continue to power critical operations for the exact same reasons. From aviation to enterprise IT, the story isn't about old technology refusing to die — it's about why replacing it is often far more complicated than it seems. Want even more info ?

The Failover That Failed Successfully : Lessons from a Successfully Failed Disaster Recovery and Failover Test

Conducted during a busy release weekend, the failover test exposed gaps not in the technology itself, but in coordination and communication. While production ultimately stayed unaffected, the situation quickly escalated as subcontractors weren't aligned, assumptions didn't match reality, and information didn't flow when it mattered most. We unpack how a well-intentioned test turned into a coordination challenge, where timing, dependencies, and unclear responsibilities created confusion across teams. It's a story about how resilience isn't just about systems and infrastructure, but also about people, processes, and making sure everyone is on the same page — especially when things are supposed to "just be a test."
