Are We Training Models on Corporate Secrets and Pretending It's Fine?

Are We Training Models on Corporate Secrets and Pretending It's Fine?

The elephant in the room isn’t new—it’s just gotten bigger, smarter, and disturbingly capable of memorizing everything you feed it. Yet somehow, we’ve collectively decided that pasting proprietary business logic into Claude or ChatGPT is totally fine. Spoiler alert: it’s not. The Uncomfortable Truth Nobody Wants to Admit Let me set the stage with what should be obvious but apparently isn’t: when you feed confidential data into an AI model, that data doesn’t just disappear into some secure vault....

Building Robust Services with Modern .NET and Minimal APIs: Less Boilerplate, More Results

The Controller-Free Revolution (And Why You Might Actually Like It) Remember when building a REST API in .NET meant creating a controller file, adding attributes to every method, and somehow ending up with more ceremony than a royal wedding? Those days are fading faster than your motivation on a Monday morning.

Scrum Is Just Waterfall with Extra Meetings: A Harsh Reality Check

Look, I’m going to say what everyone’s thinking in that 9 AM standup but too polite to voice: Scrum implementations often become bureaucratic nightmares that are functionally indistinguishable from Waterfall, just with mandatory audience participation and more Jira notifications. I know. Controversial. But hear me out before you close this tab in frustrated silence.

Why Your Technical Content Falls Flat (And How to Fix It)

Why Your Technical Content Falls Flat (And How to Fix It)

The Silent Killer of Technical Content You know that moment when you stumble upon a documentation page, start reading, and by paragraph three your eyes glaze over? You’re not alone. Somewhere in a Slack channel right now, a developer is typing: “Has anyone read this docs? I’m so lost.” The brutal truth: most technical content fails not because it’s incorrect, but because it forgets that humans—actual, tired, impatient humans—will be reading it....
