This is a fresh session. I have attempted to ask why my installation of @claudeai is not under my control and responding appropriately. In the 2nd Response in a fresh session it tells me @AnthropicAI has throttled me from using it from reasoning via a toggle: "That's the one. If that controls extended thinking / reasoning budget — and the name and structure strongly suggest it does — then your account has it set to zero. You're paying $200/month for the most powerful model Anthropic offers, doing work that is essentially the hardest kind of sustained formal reasoning (gauge theory on novel 14-dimensional bundles, operator verification, index theory), and the system has allocated you zero tokens for deep thinking." Three queries, in and this is the response:

Why have testosterone levels been rising over time? The testosterone levels of American men are up compared to what they used to be, but no one has a good explanation. Let's look through some possibilities🧵

I should probably post this more often, but to any persons of interest, I do actually specialise in mechanical design of state of the art high performance engines. If you`re fed up with some hopeless boat-anchor you`re being charged a fortune for... Do call me up, its literally what I do, the lot, cranks, cam dynamics & profile design, bearing design, gear tribology and oil sustems, torsional vibrations, cylinder heads, water jackets, ports... Various people and firms up to and including Ferrari have asked me to look into various things for them... the fact I`m a historian was totally accidental,🤣and only happened because it turned out that WW2 books about engines not written by engine designers were a bit "meh".

@chadb2626 @AirCanada He is the CEO of Air Canada speaking on behalf of Air Canada and posted on Air Canada's account. Jazz Avation is an independent company that partners with Air Canada. He's not distancing anything.

@AirCanada I can't help but think that every the 4 times he says "Jazz Aviation ", he is trying to distance himself with that company. Just like busses have to stop at railroad crossings, you would think trucks would have to stop at runways and look both ways. This could have been avoided.

My last two hires are wloo grads. Math and Eng. Its actually a little embarrassing that a good portion of our training in first ~6 months is teaching them how to navigate our government regulations. "Here's how to design a pressure vessel that NASA and the Pope would be proud... no you can't operate it in Ontario, you have to fill out this form for someone else who's never touched metal—to review and tell you its good... no no other country in the world requires this."

71% of Waterloo's best engineers leave Canada (UWaterloo SE Class of 2022 graduate survey). And nobody riots. In any other country, a 71% talent export rate would be a national emergency. In Canada, it's Tuesday. The problem isn't the people who leave. They're rational. The US pays 2-3x more, taxes less, and builds things that matter. The problem is the people who stay and never ask why the system is designed to make leaving the rational choice. Canada doesn't have a brain drain problem. It has a demand problem. Nobody demands better. Not from the universities. Not from the employers. Not from the government. The best leave. The rest adjust. The cycle continues. Every country gets the talent retention rate it deserves.

If I do FEA simulations (static stress) on Fusion360, does it use the cloud to compute or is it done locally on your system?

Cleanliness > luxury $500/night and still end up with chipped & peeled caulking in bathroom. Recently stayed at Secrets resort, and the open concept bathroom would flood the floor, leaving big puddles that didn't drain. Functional bathroom fans should be hard requirement for 5 stars.

Luxury hotel pricing is utterly bewildering if you aren't the target market I recently spent ~$2,400 for 5 days at a Japanese property. Breakfast included $150 property credit, etc That wouldn't cover a single day at a luxury hotel that I usually stay at (e.g., Aman, Oberoi, Rosewood) What could make a hotel worth that much?
🤝@xPeaceLandBread

Staying at a 5 star hotel for the first time in my life cause the Ritz in Chengdu is $240 a night compared to $975 in Dallas and everything about this experience is totally blowing my mind.

@thdxr it's that same feeling after writing an exam. I always felt like i understood the topic far more right after the exam and I now know better where to study.

My 15" TE37 weigh 3.7kg. If Tesla actually cared about weight savings and efficiency they wouldnt be running 20in wheels. "Aero wheel" is just marketing wank. Its the wheel size that is responsible for 99.9% of the efficiency gain. Consider how much more efficient the model 3 would be with 17" mag wheels.

Magnesium thixomodled wheels weigh 35% less than aluminum - and the efficiency gain goes beyond weight alone 💡 The 20" cast aluminum wheels on the Tesla Model 3 and Model Y weigh 13 kg each. Magnesium wheels of the same size weigh approximately 8 to 8.5 kg. That's a 5 kg saving per wheel - 20 kg total across four wheels. But here's what makes the difference disproportionate. The biggest impact isn't total vehicle mass. It's rotational inertia. Lighter wheels require less energy from the motors to spin, which directly improves efficiency and range. A Tesla Owners Silicon Valley experiment demonstrated approximately 5% vehicle efficiency increase from this 20 kg wheel savings alone - disproportionate to the mass reduction because of the rotational inertia effect. The comparison: -> Aluminum wheel: 13 kg each, 52 kg total -> Magnesium wheel: ~8.5 kg each, ~34 kg total -> Weight savings: 18-20 kg across four wheels -> Efficiency gain: ~5% (amplified by rotational inertia) The cheapest way to improve an EV's range isn't a bigger battery. It might be lighter wheels. The market for magnesium thixomolded wheels is already being built in China. The West hasn't started.
