Sometimes my husband will do a puzzle (wordle or similar) with me, and after we solve it, he will say something like "you're really smart" and honestly those kind of little things just make my whole day.

Like, mentally, the past couple years have been a struggle, mentally. It's been my hacker friends that have gotten me through it, whether they know it or not. Knowing so many people are putting their big brains toward doing things to make the world better or more interesting has helped.

Shame on Fortinet They tied their engineers bonuses to their sales team, resulting in NO bonuses to their technical workers Then had the NERVE to pour salt in the wound by sending a phishing test email about 2025 holiday bonuses. GROSS.

What's it made of? It's about 80-100% of something we call HDP. Human Designed Privacy. And well, it's pretty much what it sounds like. A privacy focused app framework built for humans, by humans. No vibe coding, VCs or profit motives. Sorry for the video, but We still need some space, Carol.

Sigh. Yes, I know about the moderation choices Bluesky has been making regarding NCP/NCII. Yes, I know about the massive flaws and potential for abuse that their decisions have.

Update- once she saw the dress on, she was like "you look great and I'm stealing that dress" And I went and half the moms were wearing similar dresses. And one mom was wearing a smash the patriarchy shirt, I was amongst my people. So no embarrassment.

So tonight I am volunteering at my kids theater event, serving root beer floats. And I was planning on wearing a nice business casual modest floral dress, and she instead is insisting that "I dress like a normie" So now I'm threatening to wear my shirt that just says CUM (in the doom font)
