A nice note from Nick on Veteran’s Day. My father was able to earn citizenship through military service in the Vietnam War era. My father-in-law was Naval Academy & a Marine and one of the 1st battalions into Vietnam before it was was seen as a war. I’m grateful for all who have served. But especially my roommate Tony who passed after 2 tours in Afghanistan. Likely got cancer from tar pits. RIP buddy. I can’t wait to see your daughter’s wedding.

Pretty good perspective chart about why AIPAC hate was overblown and exploited.

Love the transparency of published data showing that cloud seeding works and can have a demonstrably positive impact on the planet
Rainmaker’s first peer reviewed publication. We produced >140M gallons of precipitation, per remote sensor measurement. We’re publishing our findings from the largest dataset of unambiguous precipitation enhancement in history. Unlike most cloud seeding publications, our findings aren’t from simulation or seasonal statistics. These are physical observations of our effect. Hard proof. Link and highlights below 🧵

Generationally talented Archie McKenzie. Solving a big problem we've tried to solve for years and even more important in AI world. Spotted early by the equally talented Aditi Maliwal. Now backed by $27 million led by the #1 performing VC - Martin Casado. Great people all working together is a formula for success.
We led @generaltxn seed when it was just @archiemckenzie_ .. These days I get to work out of their office & spend time with the team every day. I’ve watched them build something special, pumped for this team!!

Thank you Mr October. Much love.
It is heartbreaking to see antisemitism in my hometown. I was born in Wyncote, near Philadelphia, and it makes me angry and ashamed to see hatred tolerated there. The numbers show this is not an abstract concern. The Anti-Defamation League recorded 465 antisemitic incidents across Pennsylvania in 2024, an 18% increase over 2023. It tracked 189 incidents in Philadelphia and 51 in Montgomery County. These reports include harassment, vandalism, and assault; they are not all classified as crimes. (adl.org, philadelphia.adl.org) Hateful expression harms more than its immediate target. In a 2025 survey of Jewish Americans, 79% said they were concerned about antisemitism, and 52% said they had worried about their personal safety because of their identity. Nearly half reported taking steps to increase their security. A research review also found that exposure to hate is associated with worse psychological well-being, more negative stereotypes, and less trust between groups. (philadelphia.adl.org, pmc.ncbi.nlm.nih.gov) It takes me back to the racism I experienced in the 1960s: signs throughout the South declaring that Black people could be refused service, along with separate “white” and “colored” signs on bathrooms and drinking fountains,”no niggers”. I remember what that hatred looked and felt like. We cannot accept it in any form, directed at any people. I wish I could be there to stand with those protesting HATE. I am asking elected officials and other leaders in Philadelphia: Where are the clear statements condemning antisemitism? When hateful language is excused or repeated, it can make hostility seem acceptable and deepen fear and division. Leaders should speak plainly and consistently: antisemitism and hate have no place in our communities. What the hell? We have to speak up. Reggie Jackson The Mr. October Guy

I grew up a poor Christian kid in Texas and Oklahoma. Homeless at 14. Never so much as met a Jewish person. So here's what I want everyone to understand about Israel...

Antisemitism is a problem for America, not a partisan problem. It’s real and it’s wrong - and having experienced it firsthand I’m not going to be lectured on it by anyone, including the Fox and Friends hosts after a bad election night. My faith isn’t anyone else’s problem. The fact that too many Americans feel like America has lost faith in them is our collective problem and challenge that we should all work on.

Want insider view on Salesforce’s $3bn buy? 1. Voice agents massively changing how enterprises interact with customers 2. Salesforce had gaps in its offering 3. Sierra is gunning for this market. Cresta has a great product. Meet them off at the pass. Invoca CEO (ex Salesforce) spills the tea 👇🏼👇🏼👇🏼
Salesforce is buying Cresta for a reported $2.7B. It already owns Fin ($3.6B) and built Agentforce Voice 3 overlapping products, 1 job: AI agents that talk to customers Why? A bet on winning AI? An admission Agentforce hasn’t worked? Or defense vs. Bret Taylor + Sierra? 🧵

A cult is not defined by what happens when you join. A cult is defined by what happens when you try to leave.
Haley Stevens is going on the Scott Jennings radio show today because she cares about honesty, kindness, and opposing bigotry.

She’s got her whole career ahead of her and she risked it all to stand on principle. You’re in the twilight of your career with nothing to lose and you’re so desperate to hang on to power that you’re caving to the Islamo-Marxist antisemites. You’re an embarrassment.
This is a despicable betrayal from Rep. Stevens. Senate Democrats are united in our support for Abdul El-Sayed, because we know he will fight for the economic interests of working families in Michigan, unlike Mike Rogers, who is a tool of Donald Trump and billionaire donors.

CBS: “Does Palestine have the right to exist?” EL-SAYED: “Yes” CBS: “Does Israel have the right to exist?” EL-SAYED: “So, uh, yes, if there is a shared understanding…" CBS: "Wait, you said-" EL-SAYED: "Lemme just..."
