Strongly recommend the Centre for Computing History in Cambridge (UK). Unlike the CHM, which should stand for Case History Museum, it has the spectacular advantage of having the computers actually switched on. I got to use a Lisa!

This isn’t even capitalism. It’s medieval lordship. Father starts a war. Sons sell the weapons to countries that need his protection to survive. Buyers know the purchase is tribute. Saddam Hussein would have recognised it instantly. The US isn’t a democracy right now. It’s a protection racket with a flag. Britain needs to face that fact - and build something different with Europe before it’s too late.

JUST IN: You do not fire your Army Chief of Staff in the middle of a war for no reason. You fire him because of what comes next. Pete Hegseth called General Randy George on April 2 and told him to retire immediately. The Pentagon confirmed it within hours. No reason was given. Not publicly. Not privately. A senior Army official told Fox News that Hegseth offered George nothing: no misconduct, no operational failure, no policy disagreement on the record. Just a phone call and a career ending in the middle of the most significant American combat operation in two decades. George is the 24th general or admiral Hegseth has removed. But he is not the 24th. He is the one that matters. The Army Chief of Staff. The man whose signature sits between a president’s intent and the order that sends soldiers across a beach or into a tunnel complex. The 82nd Airborne is deploying right now. Marines from the 31st MEU are staged on the USS Tripoli. JSOC operators are at forward bases in Israel, Jordan, Saudi Arabia, and the UAE. Kharg Island, 90 percent of Iranian oil exports, sits 16 kilometres off a coast that someone will have to decide whether to approach. And the four-star general whose job it was to advise whether that approach should happen was removed 48 hours after Trump told the nation the war would continue for two to three more weeks. The replacement is Vice Chief General Christopher LaNeve. He was Hegseth’s senior military aide before this appointment. The man who carried the Secretary’s briefcase now commands the Army the Secretary is reshaping. The chain of command did not break. It shortened. The distance between a television studio and a combat order just collapsed to zero intermediaries who were not personally selected by the man giving the order. No reason was given. That is the tell. When someone is removed without explanation during a crisis, the explanation is the crisis itself. George either objected to something or was about to. The ground option. The power plant strikes. The Kharg raid. The escalation that turned a highway bridge in Karaj into rubble on the same day he was told to leave. Something in the next two weeks requires a chief who will not push back, and the Pentagon solved that problem by installing one trained as Hegseth’s aide. A former Fox News weekend host just fired a four-star general with combat tours in Iraq and Afghanistan, replaced him with his own former assistant, and did it during a live war in which the next decision could put American soldiers on Iranian soil for the first time in history. No hearing was held. No misconduct cited. The Army woke up on April 3 with a new chief it did not choose, in a war it did not start, preparing for a phase the previous chief apparently could not be trusted to execute. The question is not why George was fired. Every general in the building knows why. The question is what order is coming in the next fourteen days that required removing the one man in the chain of command who might have said no. The war has no perimeter. The chain of command has no objectors. And the next phase has no one left to stop it. open.substack.com/pub/shanakaans…

17-year-old math prodigy gave his entire prize to Ukraine — an incredible act of generosity. Skomantas Urbonas won Norway’s national math olympiad and donated the entire award to support Ukraine’s army and healthcare. 15,000 kroner. He simply took it and gave it away. “I’ve always believed that evil wins when good people do nothing. That’s why I chose to act,” he said. He’s from Lithuania. His courage speaks louder than words. A huge thank you to him—and to his parents—for raising such a remarkable human being.

Small part of my PhD's literature review, though still a good read to recall basics: "Regime-Switching Models in Financial Econometrics" (not mine!) @simomenaldo/regime-switching-models-in-financial-econometrics-afe9f67f057d" target="_blank" rel="nofollow noopener">medium.com/@simomenaldo/r…

@FunctorFact Would have been nice if it was called ‘Hint’ 😊 Maybe there’s already a Haskell intellisense tool by that name 🤔

Your Redis client is probably your bottleneck, not Redis. Most C++ Redis clients serialize requests one at a time. No pipelining. No multiplexing. You're leaving 80%+ of your throughput on the table. There's a better way 🧵👇
