Concrete impact of AI coding: I read the very cool story www.openspace.org/stories/one-.... Even a few months ago I'd just have said, “Cool.”
Now on a whim I made a prototype in half a morning and I know I can make a full Strava app this weekend to auto-annotate my activities with Midpen preserves.

The father-son duo with the most NBA points is really funny. A hint: they became number 1 when Bronny James checked into his first regular season NBA game on October 22, 2024
Now with 38,920 combined career points, Stephen & Dell have passed Kobe and Joe Bryant for second-most points by a father-son duo in NBA history.

It's impressive in a way that Trump loves crime so much that he's even doing the ones whose names have been forgotten for a century. first “emoluments” now “perfidy”.

My biggest takeaway from the protests: be thoughtful about your SaaS spend
ICE protestors' crowdsourced tracking beats Salesforce. Lesson? Real dealflow lives in field intel, not CRMs. Google Sheets, not $50M SaaS bloatware.

What chatbot psychosis taught me about closing b2b deals
Lesson from AI spiraling: Never automate complex enterprise closing. Use AI for leadgen, then unleash human AEs like Navy SEALs. High-touch = high ACV. Let Bots sift, let Closers hunt. Drop your hottest takes below.

In all the justified outage over how Grok image editing is being abused, calls for xAI and Musk to be held accountable, and reminders not to anthropomorphize Grok - I haven't seen anyone suggesting that the X users prompting the bot to generate the terrible content should face any consequences?

I am determined as God is my witness to start the Trump fake hand conspiracy theory. His hand isn't showing signs of an undisclosed illness. It's a fake painted Halloween costume hand because his hand was already removed. It's time.
