OMG. @caseynewton @zoeschiffer this is amazing beyond amazing.

On Tuesday, Musk gathered a group of engineers and advisors into a room at Twitter’s headquarters looking for answers. Why are his engagement numbers tanking? “This is ridiculous,” he said, according to multiple sources with direct knowledge of the meeting. “I have more than 100 million followers, and I’m only getting tens of thousands of impressions.” One of the company’s two remaining principal engineers offered a possible explanation for Musk’s declining reach: just under a year after the Tesla CEO made his surprise offer to buy Twitter for $44 billion, public interest in his antics is waning. Employees showed Musk internal data regarding engagement with his account, along with a Google Trends chart. Last April, they told him, Musk was at “peak” popularity in search rankings, indicated by a score of “100.” Today, he’s at a score of nine. Engineers had previously investigated whether Musk’s reach had somehow been artificially restricted, but found no evidence that the algorithm was biased against him. Musk did not take the news well. “You’re fired, you’re fired,” Musk told the engineer. (Platformer is withholding the engineer’s name in light of the harassment Musk has directed at former Twitter employees.)

Every time I think running shoes can’t get more ugly. And I’m wrong. Every. Single. Time.

@futurebird We all have an “enteric nervous system” that controls the function of our guts. It has about as many neurons as the brain of a cat. And it’s almost completely disconnected from the rest of our nervous system.

A whole second brain inside our bodies, and we can’t communicate with it.

A cat-sized brain. And you tell me it •only• thinks about digestion? Not buying it. Does it dream?

I have not idea why I never heard about it until now, but the BIG Math Network (bigmathnetwork.org/) is a network of organizations promoting careers in Business, Industry and Government to students in the mathematical sciences, including #orms.

Elon Musk fired Twitter's entire staff in Brazil except a few salespeople.

Among those fired: "eight people who moderated content on the platform in order to catch posts that broke its rules against incitement to violence and misinformation."

Interesting comparison of modeling syntaxes. Should MIP modeling be "nudged" a bit in the direction of CP (letting the modeling language handle more common reformulations)? yetanothermathprogrammingconsu #orms #integerprogramming
