You just won a 2-week, all-expenses-paid vacation to New York. But there’s a catch: you have to stay within one region the whole time. What are you picking?

There is an accountant somewhere in Florida, fueled by a Cuban sandwich and 3 michelobs, playing better long matches than Jannik Sinner
🇮🇹 Jannik Sinner's last nine 5th sets played: Tsitsipas - AO23 ❌ Altmaier - RG23 ❌ Zverev - USO23 ❌ Medvedev - AO24 ✅ Alcaraz - RG24 ❌ Medvedev - WB24 ❌ Alcaraz - RG25 ❌ Djokovic - AO26 ❌ Cerundolo - RG26 ❌ This is his BIGGEST weakness. But what's the solution?

This is really cool - it captures what Kalshi is genuinely aiming to do. When you look at a financial instrument (even a stock, not even an option or a basket) you are up against so much weirdness…. Decay, volatility, and fundamentals are hard to price for most investors. A company can beat earnings handsomely and go down 10% for a million reasons that are abstracted away by a single price. When you get a binary market that can unbundle the complexity of traditional instruments, people end up structuring risk more elegantly (making markets work far more efficiently in the long run).

Happy to ship the first version of Hedgebook, powered by @Kalshi : an app showing how every SPX companies can hedge their core business risks using Kalshi event contract markets. Event contracts and perpetual contracts consolidated into a single, onshore, regulated exchange is how we get to perfect Arrow-Debreu markets. Thanks to @j0hnwang and @0x_ultra for inviting me to build this, and to Nicole from @KalshiResearch for inviting me to present the early frameworks at the Kalshi Research Conference in March.

silly AI tools are still inferior to a god king who reviews 95% of your company’s PRs
What is even the benefit of code review in 2026? As AI tools get better and better, I keep thinking about this. There is so much lost engineering velocity due to context switching if you have to build a feature, wait for another engineer to “review” it (most of the time they just skim and pattern match anyways) and then merge it in and wait for it to deploy (even worse if you have to address a round of comments first). With Claude ultraplan, codex review, or greptile, AI often does it so much better and faster (without the hour long turnaround time). With a high context window it’s usually way better at catching nuanced edge cases vs a human code reviewer that’s just doing it quickly anyways so they can switch back to their own work. It can literally be the difference between merging 10-20 PRs a day instead of just 4-6. I still do see some value of it in larger companies where you want to be a lot more deliberate with changes at the cost of speed since you’re serving for millions of users, or if you’re onboarding a new hire to your eng team, but requiring manual code review for your entire engineering team at early stage startups feels extremely bearish at this point

AP Swatch Car. Downfall of Jony Ive will be studied.
Ferrari has just officially unveiled its first ever all-electric car, called the Ferrari Luce. • Starting price: $640,000 • Interior co-designed with Apple's former head of design, Jony Ive • Range: 280 miles (expected EPA) • Peak charging speed: 350kW • 122 kWh battery • 1,050 horsepower • 0-60mph: 2.4s • 800v • Four-door four-seater • Four electric motors • OLED screens • Weight: 4,982 lbs • Front motors spin to 30,000 rpm, rears hit 25,500 rpm • Car uses an accelerometer to capture real vibrations from the electric motors & rear chassis. An algorithm filters out unpleasant frequencies and amplifies only the more “musical” sounds. This can be heard inside and outside the car. • Paddle shifter on steering wheel changes how aggressively torque is delivered, with five different levels • The trunk has 21.1 cubic feet of space, the largest luggage capacity the company has ever offered • 197.6 inches long, about as long as a Tesla Model S U.S. deliveries start in Q2 2027.

I asked Claude Cowork to duplicate a column in Excel today. It deleted my file and then stopped working
I installed Claude Cowork yesterday 2 hours later it had: - Created 3 brilliant pitch deck revisions for projects I’m advising - Responded to 42 telegram DMs asking for various introductions - Reviewed 9 tokenomics drafts and provided feedback with inline comments - Updated all my TradingView alerts and found 19 high R setups - Negotiated 4 tier-1 CEX listing offers and got them all for free - Reviewed market maker performance reports for 14 projects and identified the extractors - Scanned all the trencher chats and identified the next 100x’s 2 months of work. 2 hours. I panicked and closed my laptop. Opened X to look busy. Realized there was nothing to do. Took a walk. Got coffee. Reorganized my desk. Took another walk. It's now 11am the next day and I'm writing this tweet because I genuinely don't know what my job is anymore. My calendar is empty. My to-do list is empty. My inbox is empty.
