@theroberthu @edgaralandough Bc almost no 401k’s support it. Gotta be at mag7 or similar huge company to get the option.

@edgaralandough how is this not the first thing every financial advisor tells you on day one

One of my favorite loopholes in the US tax code: If a married couple earns more than $246K, they cannot contribute directly to a Roth IRA But, they can instead use their 401k to get $140K into their Roth IRA every single year Here's how the "mega backdoor Roth" works:

@Centurysouth99 @HunterAllen4 @Nostre_damus @grok Nothing. They’re based on the 10 year yield. Don’t take my word for it - plot mortgage rate vs 10 yr yield on Fred stl site to prove it to yourself

@HunterAllen4 @Nostre_damus @grok @grok what happens to mortgage rates

US 20Y yield just hit 4.99% we all know what happens next

@signulll It’s the people that don’t fly delta that make it premium. Elevated cost is a great filter for the Walmart of passengers.

it's unfathomable how much airlines have made travel really really painful unless you have status or pay an additional $200 for an *economy* plus seat so you can actually have overhead space to put your damn bag. it's almost like the entire process was designed to inflict pain wherever possible to extract the most amount of money from an individual. delta is especially good at this which is why they're the most profitable. for some reason they are considered premium? for what exactly? brands that have pitched themselves to be "premium" rarely ever are, like verizon or delta, both overrated & pure trash. i literally switched to metroPCS from verizon & it's 100x better with 25% of the cost.

@fmfclips Why not prescribe vascepa then?

Taking ~2 grams/day of fish oil is enough to move most people from a low omega-3 index (~4%) to the optimal range (~8%), with major benefits: • ~90% lower risk of sudden cardiac death • ~5-year increase in life expectancy (at higher omega-3 index levels) • Lower risk of dementia and other neurodegenerative disease • ~30% reduced heart attack risk (VITAL study) • ~25% fewer adverse cardiac events (REDUCE-IT trial) Concerns about “oxidized fish oil” are often overstated Quality definitely matters, but the bigger risk is not getting enough omega-3s at all

@mjscarangella @N8nK8 @kglightspire @bscholl Are you talking fuel efficiency or specific power or something else? What kind of percentage differences are there between SOTA commercial GE and Russian or Chinese engines?

@N8nK8 @kglightspire @bscholl Pratt & Whitney working with General Electric, Snecma of France - even Volvo licenses GE engines. The Chinese and the Russians have never closed the Gap and boom aerospace is never going to make a compressor as good as General Electric, just like Pratt doesn't.

First batch of Boom-made compressor (HPC) blades are ready. Trivia: Any idea why they have a small slot?

@tonyver45 @Object_Zero_ No, too expensive and hard to certify. Aw609 is in or near year 20 of cert.

@Object_Zero_ Are the big players looking at this for commercial use ? Obviously one would expect them to focus on the military applications at first.

Tiltrotors I always liked the idea of a tiltrotor, the concept combines the convenience of a helicopter with the speed and range of a private jet. It falls between the two, 310mph and 1,200mile range. Double the speed and range of a chopper, half the speed and range of a jet But a pressurised cabin and you can VTOL on a helipad, or anywhere really, so you can skip the airport. It means you can do 300mph point to point trips anywhere within 500miles of an airport. This really unlocks densely populated places like much of Europe (UK, NL, BE, FR, DE, SI)

@StephenFleming @Object_Zero_ Wind gusts and unstable transition basically obsoleted that concept.

@Object_Zero_ Tilt-wing works better than tilt-rotor…

@YoungMantis2 Best place to get bent: Necto

Where is the best burger and place to get BENT at the University of Michigan 🤔

@CalumDouglas1 What was the most impressive or interesting F1 tech you worked on or were aware of?

ASK AN ENGINE DESIGNER! In an attempt to find out more about my audience (and to encourage more followers... *cough*), I will happy answer below (if I can) any question you might have about how engines are designed. Note that I dont deal with the details of engine electronics much or mapping, so you wont find I know very much of interest there. But I have been personally responsible for about 4 complete engines which were taken from not existing at all, to existing and running, and have designed at least one of most fundamental components, up to and including at F1 level (I`ve done one F1 cylinder head, a F1 geartrain), and a LOT of other bits and consultancy. I am also officially registered as an external consultant to the UK Govt Aircraft Accident Investigation Branch for certain historic aero engine failures (thankfully the only investigation I was called in to did not involve any fatalities other than the aircraft & engine themselves) Normally people get charged a lot of money for advice like this so the only caveat is, you have to re-tweet this to ask a question. If I know, I will answer it, however please do NOT ask for any very specific details about F1 stuff as NDA`s prevent me revealing company specific things, so dont ask me what kind of fuel injector spray pattern the Red Bull engine has, but do ask: "how on earth do you design a bolt ?" or more generally applicable questions.

@Kotoquang Some are, the power density is a mirage when you factor in the weight of all Associated components, and get to aerospace levels of safety. Evolito does axial flux. Summary is there is no magic bullet, even on motor topology.

Why aren’t those hyper power dense axial flux motors being used for EVTOL?

@Atomic_Ferret @Andercot You’re 100% right

I kinda don’t think so. In the 60s through the early 80s, many major cities had heliports on the rooftops of skyscrapers. Often used by execs to fly directly to their buildings, there was also regular passenger service. There were 1-2 crashes and that put an end to it. I doubt they will let tens/hundreds of thousands of them take to the skies anytime soon.

There's a certain energy density for batteries that will suddenly "turn-on" the economics of short-range eVTOL, and in high-density areas trips anywhere from 5-200 miles will be with small autonomous electric aircraft. All of a sudden the roads will be empty

@dr_obbs Anti-squat can be achieved with or without anti-lift. Antisquat responds to acceleration forces, antilift to braking forces.

I’m not a suspension expert. But if you use anti squat geometry for your rear suspension, doesn’t this make you more susceptible to rear lift on hard braking? Maybe that’s why the rears locked up under hard braking? All the load would be on the fronts, and possible unload the rears?

@shaneparrish What year was the $70k figure derived? Seems out of date with modern inflation, and geographically dependent.

11 Takeaways from my interview with Daniel Kahneman: 1. Delay Your Intuition: At 22, Kahneman redesigned the Israeli army’s interview system. The old way relied on gut feelings about recruits, and it failed badly. His fix: make interviewers score six specific traits separately, write each score down, then after completing all six scores, close their eyes and give an overall intuition. The interviewers revolted. “You’re turning us into robots,” one complained. But when they tested the new system, it worked dramatically better. That “close your eyes” instruction survived in the Israeli military for 50 years. Most people form an impression in seconds and spend the rest of their time confirming it. The best wait for all the information before letting their intuition speak. 2. Loss Aversion Creates Permanent Programs: When you own something, losing it hurts twice as much as getting it felt good. Once people have a benefit, you can’t easily remove it. When you try, they fight like crazy. The 100 people losing a government subsidy scream louder (and organize better) than the million paying for it. That’s why the government only grows. Every program creates fierce defenders. Nobody fights as hard for lower taxes. Once you give people something (a perk, a feature, a benefit), it’s nearly impossible to take back. The founder who wouldn’t offer free lunch on day one can’t cancel it on day 1000. Small groups losing something specific beat large groups gaining something abstract. Every time. 3. Your Rules Become Your Default: Kahneman’s phone rang during the interview. Someone wanted a book review. “My rule is I never say yes on the phone,” he said. This wasn’t about being difficult. Danny was human just like us, he often said yes to things he didn’t want to do. So he created a rule. Not a goal, not an intention, a rule. It reprogrammed his unconscious mind and turned his desired behavior into his default behavior. 4. Facts Don’t Form Beliefs: “I believe in climate change,” Kahneman said. “I believe in the people who tell me there is climate change. The people who don’t believe in climate change, they believe in other people.” This is how we form all beliefs. We don’t examine evidence and reach conclusions. We trust people we like, then adopt their views. “The reasons are not the causes of our beliefs,” he explained. They’re stories we tell ourselves afterward. Want to change someone’s mind? Facts won’t do it. They need to trust you first. If they admire you, they’ll find reasons to agree. If they dislike you, the best evidence won’t matter. Smart people believe opposite things because they trust different people. 5. The Julia Fallacy: You have the following information. Julia is graduating college. She read fluently at age four. What’s her GPA? You just thought of something around 3.8, and Kahneman knew you would. Here’s why: a four-year-old who reads fluently seems exceptional, maybe 90th percentile. So your brain assumes 90th percentile everything. “It’s idiotic statistically,” he said. Early reading barely predicts college performance. Doesn’t matter. We can’t help ourselves. Stellar interview means stellar employee. One bad presentation means the person can’t teach. Our predictions match our impressions, even when they shouldn’t. 6. Winners Want the Score, Not the Prize: Why do billionaires work 80-hour weeks? “They’re clearly not doing this because they need more money,” Kahneman observed. At that level, money becomes proof that you’re good at what you do. His research found that past $70,000, extra money doesn’t make you emotionally happier, it just makes you more satisfied with your life. And these are completely different things. Happiness is social, it’s being with people who love you. Satisfaction is conventional success: money, prestige, achievements. The tragedy? “People don’t seem to care about how happy they’ll be. They want to be satisfied with their life.” We optimize for the story we’ll tell, not the life we’ll actually live. 7. Behavior Is Situation, Not Personality: When someone acts like a jerk, “look at the situation they’re in,” Kahneman advised. We instinctively blame personality. Psychologists call this the fundamental attribution error. When others speed, we think they’re reckless. When we speed, we know we’re late for something important. “People do good things for a mixture of good and bad reasons, and they do bad things for a mixture of good and bad reasons.” The kindest person will snap under enough pressure, and the worst person will help when the conditions are right. Change the environment, change the behavior. 8. Algorithms Beat You Every Time: “If you can replace judgements by rules and algorithms, they’ll do better,” Kahneman said. Not sometimes, always. We trust our judgment and value human insight, but we’re consistently wrong about this. The real problem is that we prefer confident, intuitive leaders to analytical ones. “People want leaders who are intuitive,” Kahneman observed. We choose the leaders who make us feel good about ourselves, not the ones who make good decisions. 9. Wherever There’s Judgment, There’s Noise: An insurance company asked Kahneman to test their underwriters. Same exact cases, same information, 50 different people. The executives expected maybe 10% variation in quotes. The reality shocked them: 50% variation. One customer gets quoted $10,000, another gets $15,000 for the exact same coverage. “Wherever there is judgment, there is noise, and more of it than you think,” he said. The solution is simple: use algorithms or structured procedures. But companies would rather live with expensive chaos than admit their experts disagree with each other. 10. Legitimize Doubt: Before making a big decision, Kahneman recommended this technique: gather your team and say, “It’s two years from now. We made this decision and it was a disaster. Write down what went wrong.” He loved this because timing is everything. “When people are coming close to a decision, it becomes difficult to raise doubts,” he explained. Anyone slowing things down becomes the enemy. The premortem flips this dynamic, it doesn’t just allow dissent, it requires it. It won’t prevent every mistake, but it forces you to face the problems everyone’s trying to ignore. 11. Clear Intuitions Fool Experts: Experts see all the options. You don’t. When economists design policies or product managers add features, they imagine users comparing every possibility. But you take a job and forget the others existed. You buy a house and stop thinking about the ones you passed on. Life isn’t a menu where you see all choices side by side, it’s one door closing as another opens. “They are completely lost between clear intuitions and strong intuitions,” Kahneman said. The expert thinks small differences matter because they can see them all. You can’t see them, so they don’t. That’s why economists botch predictions and why your phone has 50 features you’ve never touched. All of this packed into an hour? Yes please.

@Kotoquang Being evtol doesn’t mean they aren’t using cyclic or collective. Some are, some aren’t.

Helicopters are insane, every blade is individually articulated during every rotation! So much mechanical complexity that is just eliminated in multi-rotor EVTOLs or quadcopters.

@clintcarlos @Austen Check out rents vs home prices in Orange County. Closer to 4500-5k vs 10k mortgage.

@Austen Also, let’s be real here, there’s no way someone is renting out a house for $4200 that they’re paying a $12,000 mortgage on. Landlords aren’t subsidizing renters to have a negative $8K monthly net cash flow ($100K annually) on a property. This isn’t happening.

Because 30 years from now: Renting: $13,000 - monthly rent $0 - equity $0 - written off on taxes vs $0 - mortgage $4m - equity $1.5m - interest written off on taxes It may not make sense for certain financial scenarios, but people buy things to not make payments one day.

@ShadowofEzra Idk if this is true, but their claim is when it’s injected high enough in the atmosphere, so2 poses no risk to people, and the amt required for acid rain is several orders of magnitude higher than what they could ever release. If their claims are true it could be effective.

A private company in California, Make Sunsets, is launching balloons to release sulfur dioxide into the stratosphere, aiming to reflect sunlight and combat global warming. Sulfur dioxide is a regulated pollutant under the Clean Air Act, strictly overseen by the Environmental Protection Agency. This toxic compound is notorious for triggering severe respiratory problems, causing skin burns, and fueling acid rain. And once it’s released, there’s no escape—it will return, seeping into our air, water, and food.

@_adumbo_ @emm0sh I like it bc it lets the machinist decide how they want to split the tolerance between position and size. That being said, in practice it still freaks out the majority of shops until you explain it.

@emm0sh The joke is most likely going over my head here, but wouldn't that make the MMC redundant (ie no bonus tolerance)? Or do I not understand MMC/LMC clearly enough (most likely scenario)

engineers deciding to use zero positional tolerance on an MMC

@SenAdamSchiff This is equally on your party. You chose to run a geriatric and let him pick a token black woman who couldn’t even poll at 1% in the primaries. Now all of America gets to pay, and hopefully you personally get to pay for being complicit.

FBI Director nominee Kash Patel promised no retribution. The next day, we have this grotesque purge at the FBI. Bondi said she would examine pardons on a case by case basis. Then Trump gave 1550 pardons overnight. Their confirmation commitments mean nothing.

@gunsnrosesgirl3 Another garbage post from someone that has never picked up a wrench in their life.
