My best engineer stopped complaining about our massive tech debt. I told myself they had finally accepted the roadmap. Six months later, I understood what they were actually telling me:

Proud to announce I am returning as Team Principal for @HaasF1Team! I have mended my relationship with Gene as he finally wants to reach his hands down his pockets and hand me some focking money. I’m excited to re-cement my place in the F1 Team Principal hall of fame!

Britain's new High Speed 2 (HS2) railway is to be operated by 'thermally actuated traction locomotives', according to an announcement by the UK Government's HS2 Secretary John Oak. The technology is understood to be a modern variation on traditional steam locomotion and has been proposed as the latest cost-cutting measure in Britain's controversial – and hugely over budget – high speed rail project. The announcement comes a week after the government confirmed it was considering running slower trains on the line in an effort to bring costs under control. HS2 is designed to operate trains capable of reaching 360kph (223mph) but the newly announced TATL trains are expected to have an operating speed of just 160kph (100mph). Commenting on the news, Frank Ake, chair of the railway lobbying group "Britain Needs Speed" said: "This is a total joke. HS2 is one of the most mismanaged infrastructure projects in Britain's history but even so, how anybody could believe this is beyond me."

A 71 year old man dies in March. Will. Trust. Beneficiaries on every account. He did everything right. BUT he kept his entire life on his IPHONE. Banking apps. Brokerage accounts. Crypto wallets. PayPal. Venmo. Credit cards. Passwords. Financial records going back many years. And every photo he ever took. His grandkids. His anniversaries. Years of family memories that exist nowhere else. His wife found a passcode scribbled on a piece of paper in his desk drawer. It didn't work. She tried everything. Nothing worked. What followed was months of frustration and thousands in legal fees recovering accounts and memories that were never hidden from her. A perfect estate plan on paper. Zero estate plan for his phone. Nobody ever told him his smartphone needed one too. Here's the free two minute fix that could have saved her all of that. 🧵

@JagvarGames @SandyofCthulhu An Oggie is not a bread bun, it's slang for a Pasty. From the Cornish word hoggan.

@SandyofCthulhu In the UK we actually fight over such things.

My buddy had to stay in Nottingham for 6 weeks in 1990 to do quality assurance on a game. They had a little sandwich shop that was only open for lunch. One of the main sandwiches was the fabled "bacon bap". One day he went there and said, "I would like a bacon bap. But please toast the bap, add a slice of tomahto, a piece of lettuce, and a smear of mayonnaise." They made it, and then said, "Wow that looks good." He took it to his cubicle and his English co-workers came by asking "What's that? What's that?" He said, "It's a bacon lettuce tomato sandwich - a BLT." They asked for the recipe, and he told them the name is literally the recipe. They scampered down to the lunch shop and all got some. The BLT, previously unknown, became the most popular sandwich at those offices. Britain has great bacon, good tomatos, and fine lettuce. But at least in Nottingham 1990, they had never put them together to make what is, objectively, one of the great sandwiches of the world.

@MoreAverage48 @F1JayyUK @VolksVuur From what I have read, the driver does not decide when the battery power kicks in, its part of the ECU engine map.

@F1JayyUK @VolksVuur It's a skill issue. These are supposed to be the greatest drivers on the planet, yet they don't seem to realise they need to drive the cars they're given. Definition of skill issue.

Pretty damning from Lando this is. “Honestly some of the racing, I didn’t even want to overtake Lewis. It’s just that my battery deploys, I don’t want it to deploy, but I can’t control it. So, I overtake him, and then I have no battery left, so he just flies past. This is not racing, this is yo-yoing. Even though he [Hamilton] says it’s not, it is yo-yoing.”

The sickest men I've ever worked with were the most disciplined. Not the guys eating pizza and skipping workouts. Those guys felt bad and knew why. They weren't confused. The truly fucked up cases walked in with bloodwork of a dying 90 year old. And they had done everything "right" for years. Plant-based because the documentaries told them meat was killing them. 5am wake-ups because a podcast said to harness the cortisol peak. 90 minutes of cardio 6 days a week because the Apple Watch said close your rings. 1,600 calories because a fitness influencer said abs are made in the kitchen. 18:6 fasting because a longevity researcher said autophagy. Every optimization hack that went viral in the last 3 years. They did all of it. Their bloodwork: > Testosterone: 240 at 33 > Free T3: 1.6 (thyroid at starvation output) > B12: below detectable range > Ferritin: 8 > DHA/EPA: functionally zero > Cortisol at 10pm: 24 (should be near zero) > Zinc: depleted. Iron: depleted. Retinol: depleted. > hs-CRP: 6.2 (massive inflammation despite "clean" eating) Sex drive gone. Muscles wasting despite training hard. Brain fog so thick they couldn't hold a conversation. Emotional flatness they described as "watching my life through a window." They weren't sick because they were lazy. They were sick because they were obedient. The guy I have right now eating steak, potatoes, and butter three times a day with zero optimization? Total testosterone: 780. Sleeps 8 hours. Warm hands. Morning erections. Clear head. Doesn't think about health because his body just works. One man ate what humans have eaten for 200,000 years. The other ate what the internet told him to for 3. The rebuild if this is you: > Stop the deficit immediately. 2,800-3,200 calories for an active male. Your body cannot produce hormones in a famine state. > Reintroduce animal foods. Red meat 4-5x per week. Eggs daily. Liver once a week if you can stomach it. These contain everything that was missing. > Cut the chronic cardio. Replace with 3-4x resistance training and daily walking. Chronic cardio in a deficit with tanked hormones just drives cortisol higher. > Stop fasting until your metabolism recovers. Eat within an hour of waking. Eat before bed. Your thyroid will not upregulate on an empty stomach. > Get bloodwork at baseline and again at 8 weeks. Test everything above. Watch the numbers move. Your diet should not require 14 supplements to fill the gaps it creates. If it does, the diet is the problem. Full nutritional rehabilitation protocol is on my substack. Every phase, what to eat, when to eat, which markers to track, and what to expect week by week.

A brilliant statistician who spent 50 years studying why massive engineering projects fail realized one terrifying truth: Individual incompetence is almost never the actual problem. His name is W. Edwards Deming, the man who famously rebuilt Japan's post-war manufacturing empire from scratch. He argued that we obsess over individual performance and completely ignore the environment. Here are 4 operational frameworks he used to build elite, failure-proof organizations:

You're looking at the world's busiest international airport at 40% capacity. The fallout from this empty terminal is about to hit your gas price, your grocery bill, and your 401k. Dubai's airport moved 95 million passengers a year. Since Iran started striking Gulf states on February 28, the airport has been hit by drones four times. British Airways canceled all flights to Dubai through the end of May. Lufthansa, Air France, KLM, Cathay Pacific, Singapore Airlines, Virgin Atlantic. All gone. The hub that connected three continents is barely open. But that's the part you can film on your phone. Dubai's main shipping port and the business zone around it make up 36% of the city's economy. A missile set a dock on fire and shut it all down. Property values crashed 35% in two weeks. The two biggest developers lost about 40% of their stock value. Five-star hotels running below 20% occupancy. In one month, $44 billion in stock market value just vanished. Went through the fund data on this. Gulf governments hold about $6 trillion in investment capital (basically giant national piggy banks filled with oil money). That's 40% of all government investment funds on earth, and none of it is sitting in a vault. In 2025, these funds amounted to $132 billion in the US alone. One Abu Dhabi fund sent 57 cents of every dollar it invested to America. Saudi Arabia's fund bought into Heathrow Airport and led a $55 billion deal to buy EA, the company that makes FIFA and Madden. They're co-investors in AI data centers going up outside Paris. This money is already in your economy. Last May, Gulf leaders pledged $2 trillion in US investment during Trump's visit. Fighter jets, Boeing planes, AI chips, and data centers on American soil. Those deals don't close themselves when your country is getting bombed. The Strait of Hormuz is a narrow waterway between Iran and Oman. One in every five barrels of oil on earth flows through it. Iran shut it down in early March. Oil spiked to $126 a barrel. The International Energy Agency called it the worst energy disruption in history. Countries released 400 million barrels from emergency oil stockpiles. The Dallas Fed estimates it could knock 3 points off global growth this quarter. Goldman Sachs put the odds of a US recession at 1 in 4. Ninety percent of Dubai's residents are foreigners. British teachers, Indian engineers, Filipino nurses, American bankers. A lot of them left. Charter flights out of the city sold out within days of the first strikes. Dubai sold the world a simple pitch for 20 years: move here, pay zero taxes, raise your kids in the safest city in the Middle East. That pitch died on February 28. And $6 trillion in capital that was parked on the back of that promise has to go somewhere else now.

@silasdenyer @the_zb_ Colapinto's car have two short flashes just at the moment when Bearman was up the back of Colapinto. At which point it's like giving Bearman a brake test.

@mallocblock @the_zb_ Err, they do. Colapinto wasn't harvesting when he moved across. He had harvested before the previous corner. Bearman could see all this from way back over a long period - he wasn't unsighted.

This is 100% correct. The FIA isn’t touching that one with a ten foot pole, because it would open up a can of worms they couldn’t shut. But two things are certain: 1. It was a deserving penalty for an unsafe move from Colapinto, reactionary or not 2. the accident was as bad as it was due to the regulatory framework creating HUGE speed disparities between deployment and harvesting. They are bypassing this one to avoid the potential ramifications, because there’s not yet a solution, and they can’t allow the racing to be rendered “unsafe”.

@thinkdefence For another travesty and waste of money look into what they did to RAF Lyneham.

Selling off RAF Macrahanish was really rather misguided wasn't it

@Gusse89 @Tom97___ And when the battery runs out on the car in front, they suddenly and with warning to the car behind, slow down rapidly like they were brake testing them. Which is dangerous.

@Tom97___ There should be more overtakes since one is using his battery to overtake, then he's battery is empty then the one he overtook has the battery to overtake. Then he is out of battery and the other one overtakes again. Round and round we go. Is it boring? No, not really.

F1 is in a weird place for me at the moment. I've given it 3 races to gather some thoughts and I've got really mixed feelings. I'm leaning towards these regulations being negative on a 60/40 split (I'm close to 50/50). 1️⃣🟢 The racing has improved. We're getting far more overtakes and that makes the races easier to watch. More overtakes is never a bad thing! 2️⃣🟡 However, I can't shake off the thought, the methods of those overtakes we see go against what F1 stands for. 3️⃣🟡 Also, Tyres mean very little in race strategies in 2026 which is a shame, as the Hybrid is the protagonist. If they had equal importance, F1 would be a strategic chess match! 4️⃣🔴 The biggest gripe for me is Qualifying. Regardless of the hybrid/combustion split, F1 cars should be able to go 'Flat Out' for at least 1 Hot Lap, and that isn't the case in 2026.

@grok @haluandotco @verstappenews For tracks like Monza it would have meant a 17kmh speed difference allowing for the 107% rule during qualifying.

@grok @haluandotco @verstappenews With the 107% rule used in qualifying what would be the max speed difference between fastest cars and the car just managing 107% at all the races in 2025?

Franco: "The big issue is the closing speeds, they're so different. He was probably like 50kph quicker than me. When I saw him, he was already on the grass. The issue is that it literally looks like outlaps vs pushlaps. It's very tricky to race like that, it makes it very dangerous." "I'm glad he's okay, I saw him walking, i'm glad he's fine."
