A scripts basically acts as reusable component. Script has around 20 inputs to modify each instance. Not only obvious like size or particle count, but also particle alignment towards the planet, tail chance and size, rings tilt and height, fog, tilt, pulsing - it's endless. Rive

🫯 A conflicting physical ontology ! One of the strangest properties in particle physics is the spin. The term spin is a historical misnomer. Electrons (𝑒⁻) do not physically rotate like a spinning top or a globe. Spin is a fundamental quantum property known as intrinsic angular momentum which exists as an inherent characteristic of the particle, much like its mass or electric charge. In quantum mechanics, electrons are treated as fundamental point-like particles with zero size, making the concept of physical 3D rotation nonsensical. A rotating electrical charge creates a magnetic field. An electron naturally possesses its own detectable magnetic field. Even though the electron isn't physically spinning, it acts exactly as if it were because of that. Moreover the spin of an 𝑒⁻ has orientation. As 𝑒⁻ carry a negative electric charge, their inherent spin turns them into tiny bar magnets. Two possible orientations exist in the natural state of the 𝑒⁻, spin up and spin down. When measured along a specific direction (called the z-axis) the 𝑒⁻ can only display one of the two orientation state, up or down. But the strangeness goes a bit further; when an 𝑒⁻ is misplaced or removed from its own orbit, it takes two full circles (720°) to return to its original quantum state. The spin isn’t motion, it’s an undeniable static, resilient force of this elementary particle, listed as one the fundamental constant of nature. 🔗

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.

**Traditional Engine Order Telegraphs:** The bridge unit and the engine-room unit are connected by two chains (or wire cables) that run through conduits over sprockets, forming a continuous loop. When the bridge officer moves the handle, it turns a sprocket that pulls the chain, which in turn turns the corresponding sprocket and pointer in the engine room. This classic system does not require electricity; it relies on a direct physical linkage, ensuring that both dials always mirror each other. Here’s a typical sequence of operations: The bridge officer grabs the handle and swings it to the command position, for example, "Half Ahead." This movement not only moves the engine-room pointer but also rings a bell or gong to alert the engineers. The engineers then adjust their own handle to match the position indicated by the bridge officer; this movement serves as an acknowledgment and rings the bell back on the bridge, confirming that the order has been received and understood. Only after this acknowledgment do the engineers work the throttle and reversing gear to carry out the order. It is common practice to first execute a full sweep of the handle, moving it all the way to one extreme and back before settling on the actual command position. This exaggerated motion serves two purposes: it rings the gong loudly and unmistakably, ensuring everyone is aware that a new order is coming, and it checks that the mechanism and chains are not stuck or slack. On some ships, this full sweep also signifies an important or urgent change (such as switching from ahead to astern), emphasizing to the crew that they need to pay attention because the situation is critical. After completing this sweep, the handle is adjusted to the desired position. This telegraph is from the Steamship Shieldhall (video credit as well). Go check her out on

LinkedIn wrapped is here! And it's made with Rive Stoked to be invited by BUCK to join the project. I wasn’t actually animating the thing though I had more of a technical assignment and we had quite a few things to solve. There is 9 chapters total (but not everyone sees all the chapters or even all the slides in given chapter) in 3 languages, the data being sent to Rive is raw so we had to cover for many variables: - A progress bar aware what chapters are included for given user - A progress bar checking what slides are included for and logging their duration time to progress bar - A custom slider solution (the default Rive slider is not enough if you turn contents on and off) - A State Machine logic aware of chapters or slides skipped from playback - A custom slider behavior for when there is auto-slide (instant) and tap-slide (slide animation) - A custom text-length tracker for to dynamically change font-size for long strings - A custom screen ratio tracker to scale down the UI for small screens - Handling dynamically handle big numbers (10,000 becomes 10k etc.) - Handling translations (3 languages) - Super complex behaviour for when if some data-point is missing we don’t leave a blank space, but it is being replaced with other data point instead (so some user se A-B-C, but some will see only B-C as if A never existed without leaving blank space) - Rage click prevention Amazing experience, thanks for having me. People at BUCK are absolutely goated, kudos to everyone who was helping me and to everyone who was actually doing the animations, stunning. Is it the biggest Rive exposure yet? Maybe Rive

Copepods, could stop climate change 5 gigatons of these 1mm-sized zooplankton called COPEPODS live in all the world’s Oceans. This is equivalent to 17 million 747 jets, and if you laid the jets end to end, they would go around the planet 31 times. The copepods migrate from around 200m below the ocean surface every night to feed on plants (phytoplankton) at the surface. It is the greatest mass migration of animals on the planet, and it happens twice a day. The vertical motion of the copepods moves just about as much water as the moon and the tides. The copepods eat 30 times more carbon than humanity generates from burning fossil fuels, and about 6%, or 3 gigatons, of their dead bodies and poop end up in the world’s largest carbon bank, the Abyss. The Abyss contains 500m to 1000’s of meters thick layer of organic carbon / mineral sludge with an area greater area than dry land on the planet. Yet humanity has wiped out more than 50% of marine plankton productivity over the last 70 years due to chemical and particle pollution. We have also wiped out 50% of Arctic krill, which are just as important. and we are now even contemplating dredging the ocean floor! We would not have had climate change if we had not poisoned and destroyed most of the world’s oceans. By 2045, the destruction will be complete unless we act now to stop the inevitable annihilation of nature and life on Earth. Let’s put things into perspective, in comparison to protecting nature, carbon mitigation, windmills and electric cars are almost a joke.

⚔️ Kingdom Come Deliverance first impressions ⚔️ Loving it so far, basically a medieval detective simulator that really doesn't care that you are the main character. And I'm all here for it. ▪️The WORLD is the real star of the show here and even though it's got plenty of jank and lots of copy and paste NPC faces, it just feels so IMMERSIVE. Even the UI just transports me to the times with a bright colourful medieval art style. ▪️The MUSIC I love, absolutely sells the world and basically ASMR as you trot around on your horse through the world. ▪️THE Combat is a real interesting one, it's got quite the learning curve which I actually LIKE, it definitely has some jank to it as well but I really appreciate the attempt at an original and nuanced combat system. (Having to stop your bleeding with bandages is really cool) ▪️The Story has gripped me (19 hours in so far) And while it seems a simple revenge story on the face of it, I think the story is more about Henry making his way through the world after the horrors of Skallitz. The writing quality is top notch as well as the quest design also. ▪️The CHARACTERS are amazing and the humour is top notch. I'm not sure the last time I laughed so much at a game. Henry is great and so well voiced by Tom McKay This really feels like Warhorse Studios have put a lot of love and work into making an authentic medieval world and as a bit of a medieval nerd I can't get enough of this game. A True RPG as well by all accounts, the game really makes me think hard about how to approach situations. Also I can't wait to get to KCD2.

Somalians in Minnesota have been in the news a lot. As someone who has lived in Minnesota my whole life I want to share my perspective. First we need to separate groups. A lot of people are saying things like we should deport all Somalians. That is wrong. Many Somalians were born here or moved here decades ago and they consider themselves American first. They raise families here, contribute to their communities, and see this country as home. Treating them as anything less than American is wrong. With that said there is a different group of Somalians that people in Minnesota talk about privately but are afraid to say out loud. Starting in the late 2000s and continuing since then, large numbers of Somalians were imported here from Somalia who do not see themselves as American, they identify as Somalian only. Many do not speak English, many do not work, and many do not support American law and norms. People who live in Minneapolis or around have seen this. This group has not been a net positive economically, socially, or culturally. They have also gained a large amount of political power in a short period of time. This is why you see Minneapolis politicians speaking Somalian instead of English, and why the Minnesota flag was changed to look almost identical to the Somalian flag. People in Minnesota are not surprised by the recent fraud stories. The scale is shocking but the behavior itself is not. Everyone in Minnesota has seen what Minneapolis has become, and it’s sad. Most people in Minnesota don’t say anything about it cause they know they will get in trouble if they do. This does not mean every Somalian person fits this description, and we should not generalize in totality at all. But Minneapolis is a fallen city, and anyone who lives in it or around it knows this even though most won’t say it out loud.
