In this friendly, plain-English guide we unpack what social engineering is, what ethical hackers like Rachel Tobac actually do, and how AI (voice cloning, agentic calls, deepfakes) is changing the game. You’ll learn a simple threat-modeling approach and a “polite paranoia” checklist: passkeys, number […]</description><pubDate>Wed, 20 Aug 2025 14:14:35 GMT</pubDate><category>2fa</category><category>fido2</category><category>phishing</category><category>social-engineering</category></item><item><title>Vibe Coding: The Two Sides of AI in Software</title><link>https://marcelschmitz.com/posts/vibe-coding-the-two-sides-of-ai-in-software/</link><guid isPermaLink="true">https://marcelschmitz.com/posts/vibe-coding-the-two-sides-of-ai-in-software/</guid><description>I want to talk about something I’ve been thinking a lot about as a developer here in Porto: vibe coding.

But from my perspective, after 25+ years in this game, “vibe coding” isn’t just one thing. It’s actually two completely different ideas, and how we use it, and who uses it, is a really big deal.

I needed a new website, one that could introduce me in less than 30 seconds, one that would tell anyone who wanted to know more about me a chance to read about the career so far, the work that I have done, what skill sets I have, and get to know what kind of a person I am.</description><pubDate>Wed, 23 Jul 2025 17:59:57 GMT</pubDate><category>introducing</category><category>personal</category><category>website</category></item></channel></rss>
