AI isn't going to kill the software industry
I feel like half of my social media feed is composed of AI grifters saying software developers are not going to make it. Combine that sentiment with some economic headwinds and it's easy to feel like we're all screwed. I think that's bullshit. The best days of our industry lie ahead.

Shifting Cyber Norms: Microsoft security POST-ing to you
tl;dr: Microsoft and other email security scanners will visit the links in email you transmit, and run the JavaScript in those links, including calls that lead to POSTs going out.
