Was working on CSM (Cascaded Shadow Maps) blending. My CSM implementation is a little unusual, I switch cascades as late as possible, using the highest available resolution cascade. Most CSM implementations choose cascades based on view depth, the problem with that is - you waste a lot of high... resolution shadow texels, in my experience easily upwards of 50%. I figure - GPU already spent the effort to compute those shadow texels - why not use them, and get perceptually about 20-50% resolution increase in your shadows. This is not new, and MJP showed this in his code too (see below). The problem is in blending, if you use cascade projection matrix for choosing a cascade - blending becomes non-trivial. So I spent a lot of time working on that, and finally cracked it. Video shows blending of 5 cascades, the blend margin is exaggerated for demonstration purposes and cascades are pushed to the near plane for the same reason. The result is a perfect forward-only blend at the cost of a bit of ALU. Matt Pettineo is pretty much an authority on the subject nowadays, and I found his amazing repo very useful in the past:show more

👉My question to the Transport Minister is regarding ethanol blending. Earlier, the blending level of ethanol was 10%, and recently it was increased to 20%. ❓Has the government conducted any scientific studies or consulted research associations, such as the one in Pune, before increasing the blending percentage? 👉Another concern is that customers are not aware of ethanol blending in petrol, and retail shops are not displaying any details about it. It is reported that many retail shops are blending ethanol more than 20%, which may affect the mechanical side of vehicles. ❓I also have a question for the Petroleum and Natural Gas Minister. Given the current excess ethanol production in the country, are there plans to explore alternative uses for it? : Benny Behanan ji in Lok Sabha

I've been working with caustics for a while in #webGPU and one of the issues I find is that it's hard to handle caustics for complex scenes. It's easy for planes, you can save photons in a texture using either compute and atomics, or additive blending with the rasteriser. 🧵

Mark Zuckerberg: “I don’t believe in delegating” “There’s this theory that a lot of people have which is that the job of a leader is to hire people and delegate things to them. My theory is there is so much going on across the company that I can’t possibly be involved in all of it, so all these people are going to have a ton of stuff they’re going to do. But fundamentally, if there’s a decision that I want to be involved with, I’m going to be involved in it… I think that’s generally a good way for founders to operate.” Mark continues: “If you’re running the company and there’s something important — at whatever level of detail in the organization — I don’t get the logic of saying, ‘I’m not going to be involved in that.’” Of course you want to have humility that you may not have the most context immediately, but in Mark’s view, the CEO must take ownership of the company’s most important problems. To ensure that his time is constantly spent on the most important priority for the company, Mark has very few recurring meetings and tries to keep his schedule as open as possible: “II generally keep a bunch of time open so that stuff is pretty dynamic — I can wake up in the morning and be like, ‘OK, I need to work on these three things today, and I want to make sure I have a block of time where I can go do that.’” Video source: Stripe (2025)

Thodōros Angelopoulos on his film language & the reason for not liking some of Andrei Tarkovsky's movies: "Interviewer: The most important thing in your films seems to be the consistence of every single shot. It has to have its own force and build up its intensity as it goes. Angelopoulos: It is for this reason that my personal film language is based on expanding the dimension of time. Before you enter into the gist of any given shot, you have to be given the time to find out the relations between the actor and the landscape. For this reason, I love Tarkovsky's 'Stalker' (1979); 'Nostalghia' (1983), I like less; 'The Sacrifice' (1986), I do not like at all. As far as I am concerned, the Holy Trinity-that of the actor, the landscape, and the camera-is perfect in Stalker. Interviewer: In most of your films, there seems to be a sense of melancholy for the past. But the two children, who are not subject to this melancholy, are pulling you in a different direction. Angelopoulos: I believe the past is my own personal past dragged into the present by my occupation as a filmmaker. The tree at the end of 'Landscape in the Mist' (1988) is the tree from 'Voyage to Cythera' (1984), a reference to my own personal film Landscape. In the course of this picture, the children cross a film landscape in order to reach, at the end, a different film landscape, which, I believe, should offer them renewed hope. I would like to believe the world will be saved by the cinema. Cinema is my world and it is the scope of all my journeys. I am always searching for secret little utopias that will enchant me; I am doing my best to believe in the relevance of these trips I am constantly embarking on through my films." (Thodōros Angelopoulos's interview with Serge Toubiana & Frederic Strauss, 1988) P.S: Remembering the great Greek filmmaker Thodōros Angelopoulos on his 91st birthday. Clip from: Landscape in the Mist (1988) Director: Thodōros Angelopoulos

.Chad Burchill on a suggestion he gave a Valve dev that was recently implemented on Inferno: "Back in Austin I was talking with one of the devs regarding Inferno and why the map is a bit uh, and obviously retakes one of the things which leads to a lot of saving, and I was saying something like Graveyard on the A site, which never used to exist back in 1.6, is an added issue, you don't even hold it as a CT, it's not a position that you use on the CT side, it's only one that you'd use on the T Side in the retake, so that was, you know, my suggestion."

What is happening in crypto right now is a resolution of the dislocation between expectations and fair value since the election in November. This is something we discussed and warned on the roundup on November 16th and ever since price has been flat/down and there's no signs of an SBR which is very different vs the expectations that were baked in. It is because of this concern for a potential dislocation that I/we have been on defence ever since the election after being disgustingly bullish in the lead up to it. The good news is this post-election premium is now being unwound, especially in alts. The bad news is this is happening during a time of relative equity strength. As traders, it is crucial to understand that markets are forward looking and you always need to be comparing expectations baked in vs reality, and not headlines on a standalone basis. Anyway. I'm sad to see the state of things right now and hopefully not too many people were carried out here. I do think that now that a lot of this dislocation has been resolved that the worst is over, but that is dependent on a positive macro environment which I'm not sure of. Godspeed.

Marc Andreessen says he has visited Mar-a-Lago and that RFK Jr. is fully in control of the health agenda. “One of the things I learned is that RFK is really in charge of health for the country, and is working with the president.” “This whole MAHA thing he's very serious about and a lot of people, including a lot of the most qualified people I know in the field, are like, ‘yes it is long overdue that we look at the food system.’” “I'm actually very encouraged that this is now going to be a very big focus here and not just by the government, but I think also in the culture.”

Congrats to EloShapes.com on their launch! On a similar note, is out of beta and available to the public. A lot of you have been asking me what my plan is now that EloShapes is also doing 3D scans... the answer is: nothing changed! I think that competition is good. I'm a mouse nerd and a LONG TIME EloShapes user, so the more options I get as a user, the better. I really think that my vision and EloShapes, though, is fundamentally different. I've had the domain for FMM for years, I have a much larger platform in mind compared to what I built so far. The 3D scans are the necessary step for my vision, not the end goal: they never were. I am also very proud of the fact that I've been able to scan at least 5 mice in full color EVERY DAY with my own pipeline, and I think I will easily have almost full coverage of the mice people would want on the website within months. Check the video for the mice I've added in just the last few days, all textured. Apart from some of the features I've mentioned before (like the virtual hand/grip), FMM is meant to be kind of a "MyAnimeList" for mice, so that you can share your profile, like this: and then later on leverage this curated list of mice you build for yourself to be shown even more mice you might like. FMM is also a tool for reviewers and anyone that wants to share their opinions on mice. Links like this: allow you to easily share your specific points about a mouse via the annotations, viewpoint sharing and measurements. And of course, as I've said since the beginning, I will use FMM to centralize all my hard testing about sensors, dpi, and such, so that you'll be able to find EVERYTHING about a mouse, including the raw results of my standardized sensor implementation testing. So, with this said, I will keep scanning as many mice as possible and adding as many features as possible until FMM becomes what I envisioned so long ago. Join my discord if you want to keep up! I hope you'll all give it a try! Ciao!

Wes Streeting, "If you're going to provide the right prescription for a problem you need to get the diagnosis right" Cathy Newman, "You said an NHS free at the point of use was something you were prepared to die in a ditch for. Is that still the case?" WS, "Not only will I only defend the NHS as a public service free at the point of use, nothing I have seen has shaken my conviction that that is the fairest and most equitable way to provide healthcare in this country"

Working on sparse volumetric light maps for WebGPU. Got generation part sorted. The resolution is adaptive, refining near geometry and skipping through most of the empty space. The video is question uses a map that's only 10MB in size, including everything. That's less the amount of GPU memory that a single leaf takes up on one of threes in the scene, or texture on one of the sign-posts. We get about 1 sample every 30 centimeters in the world space. As a side note: gave my renderer quite the workout, rendering each probe as a separate non-instanced mesh for debugging.

Kasparas Jakucionis is still one of my favorite players in the 2025 NBA Draft. I get the concerns over the drop off in his shot late in the year, but everything about his game screams that he's a pro. Jakucionis is one of the most versatile and creative on-ball creators in this class. His footwork, use of angles, balance, and change of pace is a nightmare for defenses to deal with. He showed dynamic shot making all year and was tremendous at the rim (61.8% on halfcourt layups). Don't overthink one of the most creative and malleable players in this draft.

Quantum theory may be the most successful theory in history — and Renato Renner has proved it can't consistently describe itself. This is not a philosophical objection. It's a theorem. From there it spirals into black holes, reference frames, and why some of his students refused to continue working on the subject. This one is a quiet storm, blending the foundations of physics with something uncomfortably personal: the question of what you are.

The most amazing aspect of DeepSeek Open Source is that just the Reasoning Engine can be isolated and used with any other LLM. In fact you can have a mixture of Reasoning Engines cascade around a problem and then use an Operator type agent AI to function on the the results.

The Counter-Strike Content Scene might have a big problem on YouTube... YouTube removed my video for promoting unlicensed gambling despite it NOT containing any mention of gambling / case opening websites. They refuse to back down and at the same time they REFUSE to specify at which time the "promotion" is located. If they don't give us this information, I will not know how to avoid this in the future, and releasing videos becomes quite scary as I risk the removal of the entire channel despite not doing anything wrong intentionally. This is a extremely frustrating problem to have as I see a multitude of channels directly promote gambling sites and nothing is done to them, while at the same time I chose to NOT take gambling website money to avoid problems like this, it makes no sense. The only thing they have provided us is a link to their policy (I will share this in the post below so you can read it too if you want) which states Direct promotion of gambling is not allowed, but I repeat, there was none. As it was a documentary about a Counter-Strike player - Xantares, there were images of him wearing jerseys that had the names of gambling websites on them, but that is not a direct promotion. I'd like to ask the community to like & retweet this for visibility, and ideally if anyone is in contact with a person on the YouTube team that could give us a good faith explanation of what we did wrong, it would really help out not only just me, but the entire community because if I won't be able to release videos due to fear of getting strikes, I will not be the only creator is affected. At the same time I decided to upload the video here, on X, to invite the community to point out if they see how I broke the YT policy. Maybe I and my team just don't see something obvious, that would be the best case scenario... TeamYouTube
