The Helmholtz decomposition is one of the fundamental results of vector calculus. It says any well-behaved vector field can be split into two parts, one capturing sources and sinks through divergence, and one capturing rotation through curl.

Let me explain what just happened 👇 5 minutes before the President announced a halt to attacks on Iran… someone placed a $1.5 BILLION bet on stocks going up and dumped $192 million in oil. 5 minutes… These trades were 4 to 6 times larger than anything else in the entire market. Whoever did this wasn’t guessing. You don’t risk $1.5 billion on a hunch. There was zero public indication this announcement was coming. No leaks. No press. Nothing. The only people who knew were in the room when the decision was made. Someone in that room picked up a phone. And within minutes they made more money than most Americans will earn in a thousand lifetimes. In a single trade. On a war that cost you $4+ a gallon gas and $16 billion in tax dollars. American citizens funded this war. Politicians are profiting from it. This is not the first time. Every major announcement from this administration has had massive suspicious trades right before it dropped. Tariff reversals. Policy shifts. War decisions. This is the most blatant insider trading operation in the history of American politics. It’s not even close. And it’s happening over and over in broad daylight. You would go to federal prison for trading on a tip from your cousin. These people are front running war decisions with billion dollar bets and nobody will ever ask a single question. Nobody will be investigated. Nobody will be charged. By tomorrow this will be buried under the next satisfying headline. Just like last time. And the time before that. The game is rigged. And they’re not even trying to hide it anymore…

BREAKING: Just five minutes before Trump's announcement to halt the attacks on Iran, massive trades reportedly hit the market. In one move, $1.5 billion in S&P 500 (ES) futures was bought while $192 million in oil (CL) futures was sold. These orders were 4–6x larger than

I always wanted an Emacs world clock I could easily add cities to and shift the times (ie. find meeting times across timezones). Playing around with my own implementation. #emacs #timezones #macos #linux #oss #foss #time #madrid #london #tokyo #sanfrancisco

TIL: #Elixir productivity tip of the year You can enable hot-reload preserving LiveView state 🤯 Just update your dev.exs config to look like this and done! My development iteration cycle will be so much faster now 😍 Thanks @chris_mccord for showing how to do it! #myelixirstatus x.com/jskalc/status/…

Hey @chris_mccord could we have this in development? 🧐 Right now state is not preserved across hot reloads

Mind blown. VP pick Tim Walz was doing data science back in the 90s before it was cool

Here's a wild anecdote: while teaching high school students about genocide in 1993, Walz had them use GIS data to predict where the next one would occur. They said Rwanda. (the NYT verified this via interviews with some of those students in a 2008 story)
