The Zero-Day Exploit Clock Is Ticking

The Zero-Day Exploit Clock Is Ticking A Personal Introduction The notion of breaking into a system and making it do something its developers never intended has existed since the early days of computing. My own introduction to computing came through hacking into games — disabling or increasing the number of lives to compensate for my slow reflexes. Using TD (Turbo Debugger, from Borland — shipped alongside Turbo Assembler and Turbo C/C++), I would painstakingly try to identify the memory location that held the lives counter. Once found, one could either alter the value directly or place a NOP (No Operation) over the conditional jump. It was a task that required patience, determination, and, many times, reams of sprocketed continuous-feed paper annotated to help decipher what the code did. Discoveries were rarely kept to oneself. You shared them with others on BBSs (Bulletin Board Systems), the dial-up communities that served as gathering places for the technically curious long befor...

When Your CPU Dies: My Journey with a Defective Intel Core i7-13700K

Introduction My perfectly stable homelab server gradually descended into chaos — random crashes, segfaults, system hangs — and how months of troubleshooting, community support, and hardware swaps eventually led to one conclusion: the CPU itself was defective from the factory . If you're experiencing unexplained instability on an Intel 13th or 14th Gen system, this story might save you months of frustration. Quick Symptom Checklist If you're seeing multiple of these symptoms, you may be affected: Random segfaults in unrelated applications System instability appearing after months of stability Crashes or hangs under light load or while idle VMs freezing while still marked as "running" Issues persisting despite PSU, RAM, or OS checks or changes The Setup In November 2022 , I built a homelab server with the following components: Component Model CPU Intel Core i7-13700K (Raptor Lake) ...

The Complexity Ceiling: Where Microsoft Power Apps Needs to Evolve for Complex Development

A practitioner's analysis of friction points, mental model mismatches, and the path forward for serious Power Apps development. Introduction Microsoft Power Apps occupies a peculiar position in the development landscape. It is simultaneously one of the most accessible application platforms ever created and one of the most frustrating platforms to push beyond its comfort zone. For CRUD forms, approval workflows, and data-entry tools, it delivers on its promise with remarkable speed. But the moment a developer attempts something that requires algorithmic thinking—game logic, state machines, or complex validation engines—the platform’s seams become visible. This article examines those seams through the lens of two implementations I built: a sliding picture puzzle and a Wordle game, both created in Power Apps canvas apps. These are not typical Power Apps use cases, and that is precisely the point. They expose where the platform’s design philosophy creates unnecessary friction for t...
