Is it just me, or is Fable the pro & Opus the occasionally drunk intern? This is what my week has been like dealing with those two. #Anthropic #Claude #aigenerated #AI #Agentic #softwaredevelopment #DevOps #security #privacy #CloudComputing #infosec #cybersecurity

Even though this isn’t a true photo or from a real town, this is the kind of attitude I can get behind. This reminds me of the personality of Fremont/Seattle, Washington when I lived there. A real town with a real personality. We should have more of this in real life, a lot more whimsy.

When did it become OK for vendors to cold-text me and slide into my WhatsApp? You just trained your whole sales team to look exactly like a smishing attack. Congrats. #Cybersecurity #InfoSec #Sales #security #privacy #cloud #phishing #smishing #vishing

Spent tonight with FBI Chicago, AITP, & InfraGard. Topic: Flipper Zero. A $200 device can clone your badge and walk right through your access controls. Your org's physical security program probably didn't account for that. aitpchicago.com/event-6680905 #Cybersecurity #PhysicalSecurity

Hiring manager reality: I delete half of the applications in the first 10 seconds. Not because they're bad. Because profiles look fake. The minimum to pass the test: → Real photo → LinkedIn verified → Your actual city/state Clear it or get swept in with the bots. #JobSearch #Hiring

A startup is putting military-style drones in high school ceilings. Ceiling-mounted. Charging. Waiting. And when something happens, a pilot in Austin, Texas, decides whether to deploy pepper gel on your kid's school. Let that sink in. www.wsj.com/business/a-s... #SchoolSafety #Cybersecurity

Be on the lookout, the USPS just changed how postmarks work — so your tax returns, ballots, bill payments, and other time-sensitive mail might get stamped days late even if you mailed them on time. This could cost you penalties, lost votes, or rejected filings. www.cnbc.com/2025/12/31/u...

In 2–3 years, distinguishing what’s real from what’s AI-generated may be nearly impossible. This isn’t just a technology problem—it’s a leadership and policy challenge, and I’m not convinced our leaders or institutions are moving fast enough. 😳
