🚨 CHINESE SCIENTISTS JUST INVENTED 3D PRINTING THAT CREATES OBJECTS IN 0.6 SECONDS USING ONLY LIGHT. Researchers at Tsinghua University have developed a new method called DISH (Digital Incoherent Synthesis of Holographic light fields) that can print complex millimeter-scale objects almost instantly. Instead of slowly building layer by layer,...

The future of footwear may not be manufactured in bulk. It may be fabricated around you. That is what makes this shift so interesting to me. 3D-printed footwear is moving from novelty to a real industrial model, with market forecasts pointing to rapid growth over the next decade. At the same time, brands and manufacturers are using additive manufacturing, digital design, and custom-fit workflows to shorten development cycles and make more personalized products viable. What is new here is not just the printer. It is the system around it: → scan the foot → model the fit digitally → print the part on demand → produce closer to the customer That matters. Because once footwear becomes data-driven and locally fabricated, several things change fast: → fit gets more personal → prototyping gets faster → waste drops because you do not overproduce → inventory pressure falls because you do not need to guess demand the same way To me, that is the bigger signal. This is not just about a better sneaker. It is about a different manufacturing logic. Formlabs notes that 3D printing already enables customized orthotics with better biomechanical precision, lower material waste, and simpler digital workflows. McKinsey has also pointed to digitization and 3D design as a way to shorten design cycles and reduce sampling iterations in apparel and footwear. And once that logic matures, the use cases get much bigger: → custom athletic footwear built from gait and pressure data → hospitals producing orthotics faster and closer to the patient → micro-factories making products on demand instead of stocking shelves → footwear designed for one body, not an average body That is why I think this matters now. The question is no longer whether personalized fabrication is possible. It is whether brands move fast enough before customers start expecting every product to fit like it was made only for them. Would you actually wear a shoe fabricated around your own biometric data? #AI #3DPrinting #Footwear #Manufacturing #Innovation #FutureOfWork #RetailTech #Customization #Technology

Two weeks ago I fixed one of my teeth with algorithms I wrote a couple of years ago! I got hooked by 3D scanning when I started to work for a software shop in Zurich that was programming 3D computational geometry algorithms for denture scanning to produce crowns (and more). Back then, a typical reconstruction pipeline was like: scan the patient’s teeth using an intraoral scanner, reconstruct the surface mesh, design the restoration digitally, and finally mill the crown out of ceramic. We were working mostly with point clouds and meshes, but it wasn’t just math, it was craftsmanship translated into a digital process. Every micron mattered. You could literally see how a good algorithm meant a better fit in someone’s mouth. Gaussian Splatting isn’t about surface reconstruction, it’s about appearance reconstruction. It doesn’t care about explicit topology, it captures how light interacts with the scene. In a sense, it’s the opposite philosophy of the dental world: instead of modeling what the object is, it models how the object looks. 3D Gaussian Splatting enables applications like training self driving cars, teaching robots to understand their environment, creating virtual worlds, or monitoring real sites. It represents scenes as millions of small Gaussians rendered in real time without the need for meshes or textures. Coming from a world where precision geometry was everything, this shift felt natural. It’s still about reconstruction, but with a different goal: not manufacturing a perfect object, but reproducing how the world actually looks. Two weeks ago I got my first dental crown, made with the same software, reconstruction algorithms, and Swiss precision I once helped develop. I haven’t worked there in two years, but sitting in that chair and seeing the process from the other side was a proud moment. It reminded me why I love this field.

You Can Heal Yourself With Nature Movement - By moving our body we give strength to our muscles, promote blood flow and lymphatic flow enhancing the delivery of nutrients and the removal of waste products. We also create a piezoelectric effect that energises the system. Breathing - The delivery of air into the body through intentional conscious breathing is one of the most powerful modalities for nervous system renewal, mental peace and the delivery of oxygen to the body and the removal of carbonic acid buildup from the system Sunshine - It’s my belief that the more sunlight we absorb without sunscreen, the healthier we will become. A tan looks good because it is healthy and every part of your body thrives when sunlight touches it delivering blood flow as well as a high frequency and energy Grounding - Existing in connection with the earth’s electrical fields resets everything about our energy, reduces inflammation and promotes the movement of proper channels such as detox - it’s a fantastic practice to be connected to nature. Green light - When sunlight moves through trees and leaves we receive Green light by which is very healing and high in near infrared light, in fact it is one of the most healing modalities to absorb in your skin particularly if you have any abrasions or wounds - even more powerful than red light . Fresh air - The first nutrient, having fresh air that is rich in oxygen is absolutely imperative to health and you should always have all of your windows open in the house if possible when not outside. Positive thinking - Whatever you think, shall become and having and cultivating a positive mindset that intentionally brings you positive energy is one of the cornerstones to great health. You can think yourself into sickness and you can think yourself into health so choose to view the world in a positive light and so it’ll be for you.

the letter "g". in isolation, a welcome addition to the alphabet we all know and love. but in packs, they can wreak havoc on the very airwaves we habituate, day in and day out. just think... 3g... 4g... dare i say, 5g? and don't even get me started on c-band. you thought one letter was bad? wait until you hear about TWO letters. but i'm getting ahead of myself... where were we? oh yes, the dreaded "G". already, telecommunication firms are beginning to hype up the eve of the 6-"G," a new-fangled technological miracle set to revolutionize "video streaming on the train" as we know it. but what if i told you there was a darker side to this wave of innovation? let's unmask this con-job for what it really is: a method of once-and-for-all commandeering the vacuous minds of their loyal disciples, turning the masses of mind-numbed sheep into even more mind-numbed, uhh... aphids, or silkworms, or something. don't believe me? well... take a look at this: footage leaked by an anonymous technician at sloppco communications sheds new light on this "6-G" technology, revealing it for what it is: a means of mind control. using little more than this fashionable metal propeller hat, researchers were able to directly alter this lab sealnar's thoughts and memories, all while staying well within the FDA's so called "safe exposure limits." with just 30 seconds' worth of bandwidth, the team at sloppcom were able to get this unwitting sealnar to purchase a new funko pop, with 85% success— all the way down to the correct edition, number, and finish. and according to our whistleblower, just 5 minutes of daily exposure could be enough to turn this communist-worshipping marxist sealnar into an ardent conservative.

🚨 THIS HAS NEVER HAPPENED BEFORE 🚨 🚨NOBODY UNDERSTANDS WHAT THEY JUST TRIGGERED. 🚨 🚨 People always talk about Iranian oil in terms of barrels, but rarely about what’s actually inside them. That’s the key difference—and the reason Western refineries have quietly relied on back-channel networks through places like Dubai for years to keep getting it, even under sanctions. Crude oil isn’t all the same. It’s a mix of hydrocarbons with different molecular weights, and that mix determines how easily it can be turned into the fuels refineries actually sell—like gasoline, diesel, jet fuel, and heating oil. The main measure here is API gravity. Higher API means lighter crude that’s easier and cheaper to refine, and it produces more of those high-value fuels. Lower API means heavier crude that takes more energy, more processing, and more expensive equipment, while producing more low-value leftovers. Iranian Light crude sits right in a sweet spot, with an API gravity around 33–36 and moderate sulfur levels. It’s light enough to produce a lot of gasoline and middle distillates without high costs, but not so light that it limits what refineries can make. In industry terms, it’s close to an ideal blend. Now look at the alternatives. Venezuela’s Merey crude is much heavier, with very low API gravity and high sulfur. Refining it profitably requires specialized, expensive equipment like cokers and hydrocrackers. Some refineries are built for that—but it’s not interchangeable with Iranian crude. It’s a completely different type of input. On the other end, US West Texas Intermediate is very light and low in sulfur. Sounds perfect in theory, but in practice it’s almost too light. Many refineries—especially in Europe and Asia—are designed for medium-grade crude, so they can’t just switch to WTI. They often have to blend it with heavier oils to make it work. That’s where Iranian crude stands out. It fits right into the middle of the system. It doesn’t need the heavy-duty processing of Venezuelan oil or the blending adjustments required for ultra-light US shale. That balance is why it’s consistently in demand and often priced at a premium. It also explains why countries like India kept buying it despite sanctions, and why those complex trading networks through Dubai existed in the first place. The Strait of Hormuz isn’t just a route for oil—it’s a route for this specific kind of oil that global refineries are optimized to process. If that flow gets disrupted, it’s not just about losing supply. It’s about losing the type of crude the system runs most efficiently on, forcing refineries to adapt with less suitable alternatives. That’s what’s really baked into oil prices like $82—not just how much oil is available, but what kind it is.

"Pros won’t use generative AI, and when the bubble pops, nobody will ever talk about it again." No. That’s delusional. 1/ Generative AI is already being used professionally at the level of big studios like Disney ($1B to OpenAI), and there’s zero doubt that studios like Industrial Light & Magic, Netflix, Hollywood VFX experts, etc. are already experimenting with it too. Or do you think they’re idiots? They’re not idiots at all. They have the experience and, more importantly, the DISTRIBUTION POWER. The point is: someone with taste, judgment, and storytelling experience, basically from their living room, will have access to (almost, or not even almost) the same capability as the big guys, because the pure "making stuff" skills have been commoditized, and the new way to create is just NATURAL LANGUAGE. What hasn’t been commoditized is good taste, the ability to create great stories that move people, and the ability to get them in front of people. So in the end, what wins is story quality and distribution. Having good taste, making a name for yourself, and owning strong IP (Marvel, etc.) will still matter. That’ll be true right up until AI is genuinely opinionated and can create by itself: if it comes to that, with zero human direction, stuff as good as (or better than) the very best human experts today, and on top of that, interactive in real time... Because yeah: there’s nothing in this universe that actually prevents that from happening. BUT WE’RE NOT THERE. For now, generative AI is a tool that needs direction and taste to make anything decent. And I hope it stays that way for a long time, because otherwise that’s going to be a brutal hit to humanity’s ego. 2/ On the "bubble": you have to distinguish between a stock valuation bubble (possible, I actually believe it) vs a bubble like some people imagine where it "pops" and we never hear about AI again. That obviously makes no sense given how insanely useful it is. It can only grow, and it’s going to grow fast, regardless of any stock market drawdowns (the internet kept growing even when valuations got nuked in 2000). Either way, the near future is going to be extremely interesting.

Apparently, I saw this video online and I decided to share. What this worker is applying is called bitumen, or what many of us know as bituminous coating. Most people think a wall is a solid, impenetrable block, but in reality, it is more like a sponge. Concrete and blocks have microscopic pores that pull water from the earth through a process we call capillary action. This thick black substance is the shield that stops that water from climbing up into the house. It is not about making the wall look good because this part will be buried under the dirt forever. It is about creating a skin that water cannot breathe through. When do you need to do this? The need for this arises because the soil is a very aggressive environment. Water is not your only enemy.. The ground also contains salts and sulfates that want to eat away at the cement. If this moisture finds its way to the steel bars inside the columns, those bars will start to rust. And when steel rusts, it expands, and that expansion is what cracks the concrete from the inside out. This coating is the only thing standing between your foundation and that kind of slow destruction. Thats is why if you see wet patches at the bottom of your walls inside your house, it usually means someone skipped this step or did it poorly during construction. You can apply this anytime you are building parts of a structure that will stay in contact with the ground. It is common in areas where the water table is high or where the soil stays damp for most of the year. This is a one-shot opportunity. Once you backfill the soil, you can never go back to fix it without a lot of expense and a lot of digging. It is about having the foresight to protect the heart of the building while it is still exposed. Please don’t ignore this if you need to. If you ignore it now to save a bit of money, you will be funding the future decay of your own home. I hope this helps.

In the summer of 2023, I cold emailed Jensen Huang and asked to capture a NeRF of him at SIGGRAPH. He responded in about an hour and said yes. A radiance field is, in the simplest terms, akin to a 3D photograph. A moment in time, so completely reconstructed that you can move through it and see it from angles the original cameras never occupied. NeRFs were the original method. Gaussian splatting, which debuted at that same SIGGRAPH, has since become the dominant form of radiance field. I called my late friend James, who told me we needed to begin practicing immediately. We ran capture after capture for weeks until we consistently got the capture time down to ~30 seconds with one camera. Later, in a hallway at the LA Convention Center during SIGGRAPH, I captured the portrait you're seeing now, a full 360° gaussian splat of Jensen, rendered here as a 2D flythrough. Afterward, I continued the conversation with him and members of his team to make the case for radiance fields as a foundational representation for imaging. To my surprise, they listened. Three years later, NVIDIA has several works, including NuRec, fVDB, 3DGRUT, and gsplat all utilizing radiance fields. The landscape has evolved enough that the reasoning is obvious. Gaussian splatting has begun to ship across some of the world’s largest industries, including autonomous vehicles, AEC, geospatial, media and entertainment, robotics, e-commerce, hospitality. It’s become clear that lifelike 3D is here to stay. And yet I think we will look back and be disappointed by how late we started taking 3D portraits of the people around us, just like how we have sparse 2D photos of our grandparents and great grandparents. We have billions of photographs of the people we know and love, but almost no radiance fields of them. I'll be returning to SIGGRAPH in LA where this was initially captured three years ago, with the landscape looking significantly different. Radiance fields are more under deployed than ever relative to what they can do. I'm excited for the future of imaging, and for 2D to transition into 3D. I have a few things up my sleeve that I think will make that case plainly.

When a spacecraft leaves Earth, it doesn’t just fire its engines and head straight to its destination. In many missions, especially those going beyond low Earth orbit, there’s a more subtle and elegant strategy at play, one that uses gravity itself as part of the navigation system. This is often called a gravity assist, or a slingshot maneuver. But in the case of missions like #Artemis II, what’s being used is a closely related idea known as a free-return trajectory. At first glance, it might sound simple: the spacecraft goes to the Moon, loops around it, and comes back. But the physics behind it is anything but simple. Instead of relying on continuous propulsion, the spacecraft follows a carefully calculated path through the gravitational field of the Earth–Moon system. It is launched with just the right speed and direction so that, as it approaches the Moon, the Moon’s gravity bends its trajectory. The spacecraft is effectively flung around the Moon, redirected onto a path that naturally brings it back toward Earth. No major engine burn is needed for the return. Small trajectory corrections may still be required, but gravity does the heavy lifting. That’s the key. This kind of trajectory is not just efficient, it’s also safe. If something goes wrong with the spacecraft’s engines or onboard systems, gravity itself ensures the return. It’s an inherent backup plan, built into the trajectory from the very beginning. The same fundamental idea appears in gravity assists used across the Solar System. When a spacecraft flies past a planet, it can gain or lose speed by exchanging momentum with that planet. From the spacecraft’s point of view, it’s as if it has been accelerated without using fuel. In reality, it has borrowed a tiny amount of orbital energy from the planet itself. That’s how missions like Voyager reached the outer planets, and how probes continue to explore regions far beyond what their onboard fuel alone would allow. But there’s an important distinction. An interplanetary gravity assist is typically used to change speed and direction, often increasing the spacecraft’s energy. A free-return trajectory, like the one used in Artemis II, is designed for something more specific: a path that naturally loops back to Earth without requiring additional propulsion. It’s less about gaining energy, and more about shaping a trajectory that guarantees a return. To understand why this works, it helps to stop thinking in straight lines. In space, motion follows curves defined by gravity. The spacecraft is constantly falling, first toward Earth, then toward the Moon, and then back toward Earth again. What looks like a loop is really a continuous free fall through a changing gravitational landscape. This way of navigating space reveals something deeper. We tend to think of engines as the drivers of motion, but once a spacecraft is on its way, gravity does most of the work. The art of spaceflight is not just about thrust. It’s about knowing when not to use it. #GoodLuck #Artemis NASA Artemis

If you think OpenAI Sora is a creative toy like DALLE, ... think again. Sora is a data-driven physics engine. It is a simulation of many worlds, real or fantastical. The simulator learns intricate rendering, "intuitive" physics, long-horizon reasoning, and semantic grounding, all by some denoising and gradient maths. I won't be surprised if Sora is trained on lots of synthetic data using Unreal Engine 5. It has to be! Let's breakdown the following video. Prompt: "Photorealistic closeup video of two pirate ships battling each other as they sail inside a cup of coffee." - The simulator instantiates two exquisite 3D assets: pirate ships with different decorations. Sora has to solve text-to-3D implicitly in its latent space. - The 3D objects are consistently animated as they sail and avoid each other's paths. - Fluid dynamics of the coffee, even the foams that form around the ships. Fluid simulation is an entire sub-field of computer graphics, which traditionally requires very complex algorithms and equations. - Photorealism, almost like rendering with raytracing. - The simulator takes into account the small size of the cup compared to oceans, and applies tilt-shift photography to give a "minuscule" vibe. - The semantics of the scene does not exist in the real world, but the engine still implements the correct physical rules that we expect. Next up: add more modalities and conditioning, then we have a full data-driven UE that will replace all the hand-engineered graphics pipelines.

Contrail lesson! 1. “Chemtrails” don’t exist. Just to get that out of the way. 2. Observe the satellite loop and Skew-T chart. In the IR satellite loop you can see yesterday, the West Coast had a decent short wave ridge suppressing moisture over California and Nevada. Today, you can see moisture from a low pressure over the Pacific spilling over the ridge that is now moving east of California. This is upper level moisture ADVECTING into the area. This upper level moisture is mainly above the 500mb level, or 20,000ft. 3. Now observe the Skew-T chart. Particularly clue into the 300mb level. This is a perfect example of what I talk about all the time, and why it’s important to pay attention to the 300mb level. This moisture layer is advecting particularly at the 300mb level, and synoptic scale cirrus development, and advection, typically occurs at 300mb. This is key because aircraft are flying at and above the 300mb level. 4. So, lastly, observe the pictures that I took of the sky over northern Nevada at the time of this post. You can see the layer of cirrus as well as contrails persisting in that moisture layer, exactly as depicted in the satellite shot AND confirmed by the Skew-T chart. Keep in mind that temperatures at this level of the atmosphere are typically -20 to -50°C. In this case, you can see that the temperature at 300mb is -40°C and relative humidities at this level are far different than what you experience at the surface. Any decrease in the gap between temperature and dewpoint at this level can significantly increase the relative humidity. This is why it’s referred to as “relative”because it’s far different than temperatures and dew points at the surface. So, to bring it all together, aircraft flying at these altitudes, which most commercial and military aircraft do, injecting warm, moist air from the engines rapidly into the super cooled environment, not only instantly form contrails, but when relative humidities are as depicted in this example, will enable contrails to persist for hours at a time supported by the moisture existing in that layer. This is what causes persistent contrails. These ARE NOT “chemtrails” and because they persist, does not, and will not ever, make them “chemtrails.” Now that you all needed your government to tell you that climate change was a hoax and I’ve been telling you for years that the “Geoengineering” and “chemtrail” nonsense are propaganda directly related to the climate change hoax, hopefully you can take some time to learn the basics of the atmosphere and understand what I’m showing you here, and how it works, so you’re not fooled by climate propaganda going forward. Thank you for your attention to this matter. 💪🏼🇺🇸

Jeff Bezos just told you exactly how to price AI. Nobody listened. Bezos: “AI is real and it is going to change every industry. In fact it’s a very unusual technology in that regard in that it’s a horizontal enabling layer.” Horizontal enabling layer. Three words that reprice the entire technology sector. The iPhone was a vertical. One product. One new market. Electricity was a horizontal. One substrate that rewired every market on Earth. Wall Street is pricing AI like it is the next iPhone. Bezos is telling you it is the next electrical grid. Right now, thousands of companies are trying to sell AI as a product. A feature. A tool. A subscription tier. Every single one of them will be priced to zero. You do not sell a horizontal layer. You do not compete with it. You build on top of it or you disappear beneath it. For a century, entire industries survived on one thing. Complexity. The friction of navigating law, medicine, logistics, finance. That was the moat. If you could not memorize the maze, you could not compete. A horizontal layer does not navigate the maze. It dissolves the walls. Electricity did not compete with the candle industry. It erased the need for one. The most dangerous part of a horizontal shift is how quiet it is. It moves underneath the economy. The surface looks normal. Revenue still holds. Every day you operate on the old substrate, you accumulate a debt you cannot see and cannot repay. The internet repriced distribution. AI is repricing cognition itself. When intelligence becomes a utility that runs through the walls of every company on Earth, the premium on human expertise does not erode. It evaporates. This is not a disruption. Disruptions replace products. This replaces the ground you are standing on.
