This is likely the last teaser I'll make on this as I really should have this video done this week. Here is using Windows exclusively with a controller only, rebooting the system and only using the controller to sign in and have it launch straight into Steam Big Picture Mode.

Do you know how we simulate electromagnetic radiation around real systems like antennas, aircraft, and waveguides? We break the geometry into a mesh, a collection of small elements that lets the solver compute Maxwell’s equations locally instead of attacking the whole shape at once. This makes the simulations practical, fast, and accurate enough to use in real engineering.

The Flyer is my favorite ride at Knoebels Amusement Resort. Powered by what looks to be a repurposed Allis-Chalmers tractor engine, this analog throwback is pure fun where you control the path of your gondola using only your wits, physics, and aerodynamics. LOVE THIS RIDE!

Chamath: Two terms you need to pay attention to in AI are Prefill and Decode “There's two terms that I think you're going to hear a ton about over these next few years.” “The first term is prefill, and the next is decode.” “What prefill and decode are, are two very distinct ways of how models think, and how a model goes through the process of answering a question that you ask it.” “And so when you send a prompt to AI, what happens is that the model processes it. This is called the reading phase or prefill.” “It reads your entire prompt all at once. And then it does a bunch of math, calculates all these relationships between all the words, and it stores them in temporary memory.” “The problem is that this is really compute bound. So it requires massive brute force. And Nvidia GPUs crush here.” “And their architecture is designed for massive parallel processing, which makes them really amazing at digesting these long prompts.” “So the problem just gets bigger and bigger, Nvidia just completely dominates.” “But the next phase though, this critical phase, the decode phase, is the writing phase, right?” “So the model starts to generate a response, you ask it a question and its response, one token at a time.” “And then to pick the next token to pick the next word, it has to look back at everything it has said already so that it doesn't hallucinate.” “The problem is that this is incredibly memory bandwidth constrained.” “And in our architecture, a long time ago, we made these design decisions from day one.” “And so what we did was we took a very different architectural approach, we took a very conservative process technology. We weren't pushing the boundaries of physics.” “And we used a lot of what's called SRAM. So memory on the chip so that we could do this decode thing as well or better than everybody else.” “And so now when you put these two things together, I just think it's going to create a huge acceleration in the ability for this entire infrastructure layer to get much cheaper and much more valuable, which I suspect then it'll have a lot more developer pull, you'll get a lot more applications being built, billions and billions of more people using it.”

Elon Musk on Raptor 3 Engine: "Raptor 3 is designed to require no basic heat shield, saving a lot of mass on the bottom and actually improving reliability, so that if there is, for example, a small fuel leak from the Raptor engine, it will simply leak into the existing flaming plasma and not really matter, whereas a fuel leak when the engines are contained in a box is a very scary thing indeed. It will be a massive increase in payload capability, in engine efficiency and in reliability. So this is really a revolutionary engine. Raptor 3 is really, I'd say, kind of alien technology, rocket engine. So in order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself, so everything is contained and protected. It is a marvel of engineering."

ELON MUSK: The only way to reach 1,000 terawatts of AI power is a mass driver on the Moon. "In order to get to 1,000x from a terawatt per year. The only way that we can really achieve that is on the moon with a mass driver, essentially where you do local production of photovoltaics and radiators on the moon, maybe you bring the chips from Earth, or you could conceivably make the chips on the moon, and but you need most of the mass to be made on the moon, so you don't have to transport it to the moon from Earth, and then because the moon has no atmosphere and only 1/6 Earth's gravity, you can accelerate the AI satellites into deep space without a rocket, so you can basically shoot them into space using an electromagnetic gun, like a, like a rail gun type. I mean, just, it's basically a linear electric motor, as a way to think about it."

Have you ever wondered how Starlink can keep talking to satellites moving across the sky? It uses a Phased-Array Antenna. It has many small antenna elements on a flat surface, and each one is given a tiny phase delay so the radio wave adds up in one chosen direction. That lets the beam steer electronically and stay locked onto a fast-moving satellite. In this animation, the beam pattern was generated using computational electromagnetics, by computing how the array’s directional pattern changes as those phases are updated.

Now the Mon River in #pittsburgh is beginning to get covered in snow as it falls atop the ice. Really cool to see a barge cutting through it. Roads have been decent, tons of plows out. Huge thank you to public works and PennDot clearing them as fast as the snow is falling.

COACHES: This is another HUGE pet peeve of mine. Players trying to do it all themselves and making a potential rush opportunity into a 1v1. The higher the level you play, the less likely a player will beat a defender 1v1. Especially on the rush. I see so many kids try to do it themselves - and if the kid is talented enough at the younger ages it potentially may work out. But as players advance to higher and higher levels, you rarely see anybody try to beat a defender 1v1. And even more rarely do you see anybody actually beat a defender 1v1. I see so many coaches rewarding kids at the younger ages for taking the puck from one end of the ice to the other and scoring. While it's great that a number goes on the scoreboard, you are doing a disservice to the kid's development. Because if that kid doesn't learn the value of passing and using their teammates, at some point this clip is going to happen to them. A LOT. And that player will eventually get passed by the kids that learned to play the right way with their teammates. On this clip the ANA player tries to do it all himself and the puck goes the other way and eventually ends up in the back of his net. It's hard enough to beat one person 1v1 in high level hockey, let alone skating the puck through multiple defenders. So coaches, please emphasize the value of using your teammates. I see this type of play SO OFTEN in youth hockey. Passing, hockey sense, playing with your head up, using your teammates...these skills translate to the next levels. Doing it yourself, even if it works as a young player, does not.

Work on the turret continues, we have created a controller now thanks to reverse engineering the processor memory. Sadly though it looks like the thermal imager is dead, no vacuum and unresponsive to most things we have tried.

Catherine Austin Fitts connects Iran and the control grid: "Iran... is the largest leakage... if you're [doing] programmable money globally." "This [isn't about] American national interests. [It's] a syndicate asserting... control [for] the next phase of the financial system." "Our debt is... unsustainable... [so] how do you deal with that? One way... is to implement a digital control grid." "There is likely to be an effort to put boots on the ground and... to get bogged down... for a long, long time." This clip of Fitts, a former Assistant Secretary of Housing and Urban Development, investment banker, and founder of the Solari Report (The Solari Report | Catherine Austin Fitts), is taken from an interview with Steve Kirsch (Steve Kirsch) posted to the VSRF (Vaccine Safety Research Foundation) Rumble channel on April 2, 2026. ---------------Partial transcription of clip--------------- Fitts: "There are two sides of the balance sheet here that are driving this. One of course is oil and energy, but the other is the financial control grid. Because Iran right now is the largest leakage in the system. If you're going to do a global, programmable money globally, you know, Iran and, and what Iran is doing with China and some of the other countries, puts too much leakage in the system. "So I think that what is unfortunate here is there is, there is likely to be an effort to put boots on the ground and we are likely to get bogged down in there for a long, long time. Kirsch: "So do you think that is the right thing to do for America to have boots on the ground or even be involved in attacking Iran? I mean we were the first aggressor here. We, we fired the first shots in Iran. Is that the right thing to do for our country? Fitts: "That is the right thing to do if you want to implement the digital control grid. It's not the right thing to do if you want to represent America. But this has nothing to do with American national interests. This has to do with essentially a syndicate asserting sufficient control to implement the next phase of the financial system." Kirsch: "So you think they got to Trump and convinced Trump or wasn't it really Israel saying hey, we're going to invade Iran and we'd like some— Why don't you do it with us? Because there's an opportunity and Trump saw that as opportunistic rather than this being something that is strategic." Fitts: "So the way I think of this is the White House operates within a lane that is set for them by the nature of the machinery they're running. So think of it this way. The US government spends $6 to $7 trillion a year and it gets $4 trillion of revenues and the other $2 to $3 trillion comes in from borrowing in the bond market essentially through the central bankers. "And so it, it has to, you know, and if you say to the Americans, you know, we're going to tell the bankers to go jump in the lake, the Americans say no, no, no, no, we want our check. And so you're between an Iraq and a hard place because everybody in America wants their check. "And you've got to do what the bank, you've got to operate within those lanes to make the bankers happy. And if you look at the whole US dollar reserve currency system, you've got to do whatever you've got to do to make the system go. "And right now, and the chairman of the Federal Reserve just said this... [that] the debt is growing at a faster rate than our fundamental growth rate. And, you know, if you look at one of the, you know, the big push by Kennedy and HHS to change the food and health issues in America, part of that is to get that growth rate back up. You can't get a growth rate from poisoning your people. Ultimately that doesn't work for economic growth. "So all of these issues are integrated... but our debt is growing in an unsustainable pattern. And the question is, how do you deal with that? One way you deal with that is to implement a digital control grid in a way that uses digital tokens and stablecoins to dramatically suck in more money globally into the machinery. And that's what they're trying to execute. So if you want the digital control grid, you know, what is happening makes sense."

1.0 TSI Automatic Behaviour at low speeds Peak torque hits at 1750 rpm and under that, it is believed that it has turbo lag In AT, turbo lag is well controlled and it is evident only if you go full throttle where it takes 0.50 sec to react before going bonkers! Otherwise in AT particularly, at low speeds too, with gentle throttle, it tries to remain above 1700 rpm all the time and makes drive smooth. In traffic, just be gentle with throttle. It is unbelievable that such sophisticated & performance oriented engine with 6 AT is available under 10 lakh in Kylaq. Car in video: My Slavia 1.0 AT

Forget matches; this is how our ancestors used the laws of thermodynamics to start fires in seconds using nothing but wood and air. The secret lies in the sudden increase in pressure. By trapping air in a narrow tube and forcing a piston down, you are doing work on the gas. In a closed system like this, that work translates directly into thermal energy. Because the movement is so fast, it is considered "adiabatic," meaning no heat escapes. The resulting flash of heat is intense enough to create a glowing ember, which is then transferred to a larger "tinder bundle" and blown into a flame.

Phase Space Is the Real Stage of Dynamics. So, Stop Watching the Object and Watch the State. Ordinary Space tells you where something is. Phase Space tells you what state it is in. Position alone is not enough because you also need the variable that tells you where the system is trying to go. In the animation, the left panel shows the particle moving in Ordinary Space, while the right panel shows the same system as a moving point in Phase Space. For one degree of freedom, the state is (x, p) and as time evolves, that state traces a trajectory t ↦ (x(t), p(t)) Instead of thinking of a differential equation as just a formula, Phase Space lets you see it as a flow on the space of states. For this lecture we use ẋ = p ṗ = x − x³ with Hamiltonian H(x,p) = 0.5 p² + 0.25 x⁴ − 0.5 x² #PhaseSpace #DynamicalSystems #NonlinearDynamics #HamiltonianMechanics #Mathematics
