In a world of PPO everything for reinforcement learning, I've been tinkering with SAC for training a quadruped gait. This gait is trained purely on CPU (training on one of the Dell GB10s) on a single environment. Training any particular run is obviously slower than PPO on an RTX...

Would you want to be a teacher on your staff as a principal? I have often asked teachers, would you want to be a learner in your own classroom, but the question above for administrators could be even more critical. If we do not support those closest to students every day in an effective manner, it is much harder for things to improve in schools. If we want learning to look different in classrooms, then leadership must also evolve. This doesn’t mean that everything done in the past has been wrong. Some things that mattered 50 years ago will matter now, both in learning and leadership. But replicating everything that was done in the past, whether it was effective or not, isn’t a great strategy for moving schools forward. I was blessed to learn from some amazing principals in my career, but I also learned about things that I hated as a teacher and swore that I would do my best not to replicate those strategies. I wrote this in my upcoming book co-authored with Allyson Apsey (Allyson Apsey) titled, “What Makes a Great Principal”: “If we do things in our schools and classrooms that were done hundreds of years ago that still work today, we should continue to do them. On the other hand, if we do new stuff just because it is new, but it doesn’t work, we shouldn’t be doing it. Whatever works for our community is where our focus should be, no matter when it originated.” What worked in the past? What would you change? What would you have wanted as a teacher, and how can you make that happen? Simply replicating the strategies of the past, whether good or bad, will not necessarily lead education to a better future. Innovation is crucial to leadership as much as it is to teaching and learning.

I want to know what it's like to be the best in the world? Lewis Hamilton: "It feels pretty special for a short, but a really short space of time. Like, as soon as getting there, getting there, and then it's kind of. I think it's like being at the peak of a mountain. You can only be there for a short period of time, you've got to go down again. And so, it's like the climb down and then the build to trying to do it again.I think from the outside, it looks more than it is,It feels great that you've done it and you're proud of yourself, but then you're like, straight on to the next one"

My problem with pharma isn't just what they sell. It's what they believe about you before you ever walk in the door. The industry operates on the idea that we're flawed as individuals, broken by default, in need of something outside ourselves just to function. I see the same mindset running through a lot of the political system I grew up in. The message becomes that we're a burden on the planet, a disease on it, something to be managed and corrected rather than trusted. That is not the mandate we were given. The first story ever told on this earth is that we were created in the image and likeness of God, designed as a mirror of perfection. So when someone approaches my health by starting with the idea that I have a lack something outside must fix, I have a problem with that framework before we even get to the specifics. There are real times when the body is out of balance and something outside can help. But most of what gets sold to us as longevity is really just correcting for the toxins in our environment and the way we've learned to eat. Abraham lived for centuries in the Bible. He wasn't biohacking. If we understand longevity as getting back to what was already given to us rather than adding something new, the whole approach changes. My body wants to heal. It's designed to heal. My job is to stop interfering with it.

One question that's been on my mind for years now is: could we use regular multimodal LLMs not necessarily trained for robotics to do the high level robotics intelligence part that VLAs and WAMs attempt to do? The latest explosion of powerful opensource multi-modal LLMs has, IMO, begun to make this possible due both to intelligence and speed. This is GLM 5.3 Flash, which has vision understanding, but isn't meant to be a VLA/VLM/WAM/robotics model at all, controlling an XGO mini wheeled robot quadruped with an arm & gripper. GLM 5.3F simply has access to the robot's high level SDK for controlling movement, arm joints, open/close gripper...etc. It analyzes the frames from the camera and makes adjustments all on its own to solve the task. Nothing was trained here, nothing fine-tuned for this task. Z AI did not make this model for robots and tbh I think they're surprised this works when I talk to them about it! This also works quite well with DSV4F + a vision capable model like Qwen 3.8 27B. I havent tried JUST Qwen 3.8 27B, but I'm sure it works too. I like the "logic" to be a model that's as fast as possible (but still intelligent). There's also an experimental vision version of DSV4F, I'm confident that'll work too and might even be better bc the full loop might be the fastest of all with this model. An obvious question you might wonder is: well why not use VLA or VLM? The hard part about robotics isn't object detection, that's long solved. This also isn't a solution for gait/locomotion...yet, but I actually don't think this is far away either and I've done some experimentation with LLMs in this space in the past and it does show promise. It might actually already be here for quadrupeds, since you dont need super fast IMU readings to maintain balance. I've also tried many of the larger, more generalist, VLAs that you should be able to use with popular robots and tbh there are just so many edge cases that make things hard and not work. You gotta get the camera, lighting, task, everything *just right* or the demo fails. This is for the actual hard part in robotics right now: intelligence, logic, and planning for all the ways the real world just simply isn't perfect. I've trained VLAs. They're super finicky and you're always running into sim2real issues, especially around the camera. You also have to build the whole training pipeline in a simulator, and, if everything does work, you still just have a robot that does this 1 single thing after weeks of work. If you use teleop, this overcomes the "2real" problem, but now you need to painstakingly collect teleop data, and it's only good at that specific task and that particular robot. There is a growing set of egocentric training data for "general purpose" VLAs and world action models (for humanoid form factors), but I'm really starting to wonder: Why? I think we might just sidestep this whole area of research entirely. I didn't need any training data or special environment to work with this quadruped and arm to do the task I was after. This particular quadruped and arm doesn't even exist in the wild yet really, it's a demo build from a company launching it on kickstarter, so it's not like this robot's data exists in the LLM to any real extent. I think this is cool as heck that this works and I am interested to see just how far I can push it. Also this marks the first time that I've finally got a generalist solution to a task I've been trying to solve ever since I became a dad of twins: pick up toys off the ground. This is a big day!

Kevin O’Connell tells Vikings QBs he doesn't care if they throw interceptions in training camp “There are so many things in society, not even just football nowadays, where we want to decide in a moment this guy can or can’t, this guy’s a success or failure. And it’s just not in alignment with the reality of the position or our game.” “Everything should be driven by process, and part of process is failure. Every year in training camp I give my yearly State of the Union on the first practice: ‘Just as a heads up, I’m not going to be commenting on you guys taking your stats every single day. So-and-so went 6-of-11 with two interceptions, and then we chart it for the whole training camp and decide who won or lost this position or quarterback battle.’” “I challenge the quarterbacks all the time: we’re against Brian Flores every day. This is going to be a 10-out-of-10 stress for all of us. There are going to be good days and there are going to be bad days, but I want you to be aggressive with your decision-making.” “How will we know on third-and-eight in Week 12 that you can try to fit a ball in there to Justin Jefferson on a backside in-cut? How will we know if you don’t try to do it now?” “So when you do it now, and you take the proper footwork and try to throw it into a tight window and the ball gets tipped and intercepted, let’s go back and look at it first. I’ve got no problem with the decision. What was your footwork like? Were you in your base, balance, body position? Were you playing on the timing of the play? Did you make the protection call you needed?” “If you did all those things and it was just a blade of grass different from being the best completion you had all day, now you know.” “I can finish up a practice and go to the podium and have people say, ‘So-and-so really struggled today, didn’t you think?’ And I’m like, there’s not enough time in the day for me to explain all the reasons why you’re wrong. We’re going to go in the quarterback room, we’re going to watch it, and we’re going to be better tomorrow.”

🚨 BREAKING: SAVE America Act sponsor Sen. Mike Lee reveals MAJOR PROGRESS has been made after pressure with Leader John Thune on getting it passed Lee says a HYBRID form of the talking filibuster is set to be implemented. Then, Dems will be FORCED possibly for hours or DAYS to fight against 85% of the people! Keep pushing! "We've been working closely with Leader Thune and his staff, and they've been great to work with." "What we're coming up with is something that I think is best described as a hybrid version of the talking filibuster." "But look, let's not get mired down in nomenclature. What matters far more than what we call it is what we do with it. We're going to bring it to the floor." "We're going to debate it for an extended period of time before filing cloture." "And in my view, at least, I don't want to speak for anyone else, this bill needs to remain on the Senate floor before we file cloture on the bill for as long as it takes to get it done." "Now, the fact that Leader Thune and his office have been willing to work with us on this, and they appear open to a variation of that, is a good thing." "So let's keep up the momentum, let's encourage them to continue to do this, let's put the bill on the floor, let's make those who want a filibuster speak, and keep it on there as long as possible."

Q: It must be complicated, when I listen to you, to have a private life, somebody to understand your passion and to share this moment. Lewis: "It really is, especially I would say more so today than ever before, which is the way the world is, you know. I look at the other drivers and I wonder how they're doing it. You know, some are having kids and some married, some, you know, most of them girlfriends. I did that when I was in my 20s, but I took a decision to really to maximize my time that I have here because it's not as long as you think and it's limited, you know. And I don't want to look back and be like, ah, if I just gave a little bit more here, I didn't sacrifice my time because I was committed elsewhere." "So I really focused in these last, you know, particularly these last 10 years, like get everything I can out of my performance. Then when I retire, then I can do whatever I want. You know, I can dedicate my time to whatever else it is and not have to worry." "But in this competition time, focus on health, well-being, my mental health, my driving technique, being as good an engineer as I can be, and also being the best teammate that I can potentially be for the guys that I get to work with. That's my sole focus. You know, I want to win." "I've been fortunate enough to win with great teams in the past. Particularly, obviously, with Mercedes and with McLaren, which was incredible. And my dream is to win a championship with Ferrari." "And that's something that hasn't been done for a while. But they have absolutely every ingredient that's needed to win. It's just like getting all the pieces of the puzzle in the right place. And that's what I'm trying to work on in the background with Fred and the whole team." [📹 VIGNERON GAETAN]

Putin says Russia could work with India on Su-57 jet: As far as the Su-57 goes, at one point we proposed to our Indian friends to work together on this technology. It's fifth generation technology — I think it's the best in the world as of now. But back then, our Indian friends said: "Go ahead on your own, and then we will see — maybe we'll join." The aircraft could have been our joint project. We built it independently, but we are ready to work with India in this field — to supply this aircraft and to keep developing it. We don't have any issues with it, any limitations. The same goes for air defense systems...

#SOLAR and #MOONBYUL speaking about #MAMAMOO's comeback 🐰 Next year... the article got released first, it's about Mamamoo's comeback. Rather than saying clearly that there will be (a comeback), but right now, we are in the situation where there are things that needs to be coordinated. So I think it's difficult for us to say anything about it now. 🐹 Because we don't know what will happen in the future 🐰 That's right, I think that's is why we are being careful about how we are saying things now. Whenever moomoos asked us this question, the reason why we can simply say it out is because we are at the stage where we are still coordinating. 🐹 Nothing's confirmed. 🐹 We would love it if we can do it (comeback) Because we are Mamamoo, it'll be good if we can do it 🐰🐹 But since we are in different companies 🐰 There are many things needed, the coordination etc. 🐹 If we were to comeback as Mamamoo, we would like to do it properly, just like putting all our energies into it 🐰 I want to do it properly from the start till the end 🐹 And go meet lots of fans 🐰 That's right, but since there are still coordinations that needs to be done, so I seek for your understanding 🐹 The companies are speaking with each other now as well 🐹 I had the thought of wanting to address this to all of you 🐰 Many people are asking this everywhere rather than just passing it on with a short remark, but since this is an important thing, so I think it's difficult for us to just say anything now. 🐰 As we're on this topic now, we do not have any firm answers I hope all of you can understand. 🐹 If things are confirmed, I think we will say it together like 'all of you have waited for a long time right!'. Rather than making all of you wait blindly, that's the reason why we can speaking on this carefully.

This soldiering training is the most impressive and immersive I've ever tried. It is 10x better than a YouTube tutorial video. It really allowed me to see the procedure from all the points of view, and even get super close to get the details. It is a collaboration between @gracia_vr and Imperial College London: they recorded a soldering session with Gaussian Splatting Videos (4DGS), so that you can enjoy it from your VR headset. You can see the action happening in front of you; you can pause and re-watch what you need, change the point of view, get closer, get more distant. And the quality with which it has been shot is impressive: I enjoyed this experience with my DELL Pro Max Tower T2 with NVIDIA Pro RTX 6000, and I could really see all the small details of the PCB that was being soldered! I was really impressed by it. But I also noticed some drawbacks. First of all, some scenes have artifacts that make seeing the details of the PCB hard. I think when it comes to training involving small details, the capture and reproduction of the splat should be flawless. Then, as much as I loved it as a passive experience, I would have liked to have also some sort of practice session in VR. The power of VR is to let you learn by doing in full safety, and this kind of training does not exploit it. But maybe the best way to enjoy it would be in MR, where you have this training video close to a real workbench where you do the actual soldering while following the tutorial. Gaussian Splat can really revolutionize training: this kind of recording is much better than any flatscreen experience, and more accurate than any 3D CGI recostruction.

This soldiering training is the most impressive and immersive I've ever tried. It is 10x better than a YouTube tutorial video. It really allowed me to see the procedure from all the points of view, and even get super close to get the details. It is a collaboration between @gracia_vr and Imperial College London: they recorded a soldering session with Gaussian Splatting Videos (4DGS), so that you can enjoy it from your VR headset. You can see the action happening in front of you; you can pause and re-watch what you need, change the point of view, get closer, get more distant. And the quality with which it has been shot is impressive: I enjoyed this experience with my DELL Pro Max Tower T2 with NVIDIA Pro RTX 6000, and I could really see all the small details of the PCB that was being soldered! I was really impressed by it. But I also noticed some drawbacks. First of all, some scenes have artifacts that make seeing the details of the PCB hard. I think when it comes to training involving small details, the capture and reproduction of the splat should be flawless. Then, as much as I loved it as a passive experience, I would have liked to have also some sort of practice session in VR. The power of VR is to let you learn by doing in full safety, and this kind of training does not exploit it. But maybe the best way to enjoy it would be in MR, where you have this training video close to a real workbench where you do the actual soldering while following the tutorial.

THIS !! "I've enjoyed [the weekend so far]. I've felt on it all weekend. I've felt good in the car. Q1, round one, I was feeling really strong and I honestly thought that we'd... It may be silly of me, but I thought that we were fighting for top positions. And then just the way the plan goes and where we end up waiting in the pit lane and losing tyre temperature and using one, kind of using a tyre on the out lap but then coming in and the temperature effect. All these different things just add up to not optimising the sessions. So, we'll have to do some work to try and figure out how to optimise the sessions better." "I think it's... We'll talk in the background. I think it's just... Yeah, I just have to have a conversation about it and just continue to try and improve the process. I mean, everyone's working as hard as they can. It's just... We need to also look at what the others are doing because if you look at Mercedes, they're out first and they didn't lose any tyre temperature and then they're at the front. You know, as we're waiting and turning the car off at the end of the pit lane, it just ends up losing five or six degrees and it's really hard to get that back on an out lap." "And... Yeah, when I got to Q3, I just... I had nothing. I just had no... I lost half a second in performance just from the tyres. So, that's frustrating, but nonetheless, I'll try my best tomorrow." - F1 2025 Singapore -

Alan Watts on why meditation has no purpose: Alan Watts begins by explaining the first basic reason for meditation. It interrupts our constant internal monologue: "Now, obviously, if I talk all the time, I don't hear what anyone else has to say. And so in exactly the same way, if I think all the time, that is to say, if I talk to myself all the time, I don't have anything to think about except thoughts. And therefore, I'm living entirely in the world of symbols and am never in relationship with reality." But then Watts pivots to a deeper, more counterintuitive point: meditation, properly understood, has no purpose at all. He compares it to music and dancing: "When we make music, we don't do it in order to reach a certain point, such as the end of the composition. If that were the purpose of music, to get to the end of the piece then obviously the fastest players would be the best." The same applies to dance: "When we dance, we are not aiming to arrive at a particular place on the floor, as we would be if we were taking a journey. When we dance, the journey itself is the point. When we play music, the playing itself is the point." This is where Watts delivers his core insight about meditation: "Meditation is the discovery that the point of life is always arrived at in the immediate moment. And therefore, if you meditate for an ulterior motive, that is to say, to improve your mind, to improve your character, to be more efficient in life, you've got your eye on the future and you are not meditating." Watts argues the future is an illusion we chase at our own expense: "Because the future is a concept. It doesn't exist. As the proverb says, 'tomorrow never comes.' There is no such thing as tomorrow. There never will be. Because time is always now." He pushes back against how religion has framed contemplative practice: "Meditation is supposed to be fun. It's not something you do as a grim duty. The trouble with religion as we know it is that it is so mixed up with grim duties. We do it because it's good for you; it's a kind of self-punishment." Watts closes with what he calls the real essence of the practice: "It's a kind of digging the present. It's a kind of grooving with the eternal now and brings us into a state of peace where we can understand that the point of life. The place where it's at is simply here and now."

ELON MUSK: We believe the AI5 chip will be roughly comparable performance to an NVIDIA Blackwell, and at much less than 10% of the cost Transcription: I'm super hardcore on chips right now as you may be able to tell. I have chips on the brain. I dream about chips, Literally! Because in order to have a functional robot, you have to have a great AI chip. And it needs to be an inexpensive chip and it needs to be very power efficient So we think we believe the AI5 chip will be probably about a third of the power of say something like a Blackwell, an NVIDIA Blackwell, which is a great chip, for roughly comparable performance. And much less than 10% of the cost. This is a chip that is very much optimized for the Tesla AI software stack. So it's not meant to be a general purpose chip, it's meant to be an amazing chip for the Tesla AI software And I mean a couple of things that I think make... like how is Tesla able to achieve such an improvement? I think it is because we are specialized. We're not trying to... you know, NVIDIA has to serve the superset of all past and future customers. So all of their requirements, all of the software that they've written has to work, which is a very difficult problem. Whereas we just need to make it work for our software. And so we're able to simplify the chip dramatically And then we also, I think we're unique in this, but like we have an integer-based system. And integer operations are fundamentally more efficient than floating point operations. So we can do floating point, but the vast majority of our inference is done in integer. Which is, if you're familiar with sort of logic gates, the simplicity of integer... it's integer is much more power efficient, much more silicon efficient, but you have to, you actually have to train for integer inference, which everyone else is training for floating point. That's kind of like a niche technical detail, but it's actually very important. So, yeah, this is going to be a great chip So this chip will be made in basically in four places: TSMC Taiwan, Samsung Korea, TSMC Arizona, and TSMC Texas. And we already know what improvements to make for AI6. So I'm hopeful that we can within less than a year of AI5 starting production, we can actually transition in the same fab to AI6 and double all of the performance metrics

The latest from Marco Rubio on the negotiations: “It's the reason why we're involved in this whole Ukraine-Russia conflict. That's not our war, it's not the president's war. This war started... It never would have happened if you'd been president. But this war is going on and the president is trying to end it, not because... Listen, we got a million things to focus on in the world as a country. But he's the only leader in the world that can help end it, and that's why we're... Tha- that's why even as we speak to you now, uh, Steve Witkof is in Moscow trying to find a way to end this war to save lives of eight, nine thousand people, Mr. President, as you want to know are dying every week. More people are dying a week in that war than have died in the entirety of the US's involvement in Afghanistan or Iraq. Just think about that, how bloody and destructive it is”.

"One of the very confusing things about the models right now: how to reconcile the fact that they are doing so well on evals. And you look at the evals and you go, 'Those are pretty hard evals.' But the economic impact seems to be dramatically behind. There is [a possible] explanation. Back when people were doing pre-training, the question of what data to train on was answered, because that answer was everything. So you don't have to think if it's going to be this data or that data. When people do RL training, they say, 'Okay, we want to have this kind of RL training for this thing and that kind of RL training for that thing.' You say, 'Hey, I would love our model to do really well when we release it. I want the evals to look great. What would be RL training that could help on this task?' If you combine this with generalization of the models actually being inadequate, that has the potential to explain a lot of what we are seeing, this disconnect between eval performance and actual real-world performance"

#WATCH | Delhi: On India-US trade deal, Rajesh Agrawal, Secretary, Ministry of Commerce & Industry says, "We are very optimistic and very hopeful that we should find a solution within this calendar year. But as you know, in any trade negotiations, even if there is one sticking point or issue on the mind of even one of the partners, the trade deal may not meet that deadline. The overall position is well set to deliver it in the next few weeks or months as soon as we can. But let's see, it's a call that will have to be taken at multiple levels. At the levels of negotiator, I think we are in a zone where we can say it is something that we can achieve in a very short while of time. There's not much to negotiate...As a country, we have always stood for our own sensitivities and our own uniqueness. So there are areas which are non-negotiable from our perspective..."

Arteta: “We know what is at stake and the fact that, as a club, we haven't done it for so long is a reason for that. It talks about the difficulty but I just want to focus on the things that we can control, dominate, and we have done. “It's not that we have to do a lot of new things that we haven't done. No, no, no, let's keep doing a lot of it or almost all the things that we've done for nine months, because that's what has taken us all the way there. “On Wednesday, I saw a lot of them. And today we've gone back so we need to learn, we need to be very critical of ourselves, and then pick ourselves up because on Wednesday we have a big one coming up.”

Mike Dunleavy Jr. says the Warriors are not in a situation to fix everything in free agency but they’re looking to put together a good team going into training camp: “I think there’s where you want to be in September when training camp starts, and there’s where you want to be in the spring as you try and compete for the postseason and get in the postseason. We have a couple transaction cycles here in the summer and then once again in February where we feel like we can build and maximize our team. And so I think the biggest thing is to put together a good team going into camp. And as I mentioned before, a lot of the improvement for us is going to have to come from within our habits, taking care of the ball, doing the little things. Get that knocked out, you get on your way to having a good season. We need to stay healthy and then get those guys (Jimmy & Moses) back, and then we’ll see at the trade deadline and we’ll evaluate everything. But this is not a fix-everything over the next couple weeks in free agency. We’re not in that situation based on some stuff we have going on, but we can get a lot better. We can have a good start to the season, and we can be in really good shape to make a run. But we got to get off to a good start.” (via NBC Sports Bay Area & CA with Bonta Hill and Monte Poole)

Naval Ravikant: "The only true test of intelligence is if you get what you want out of life" "There are two parts to that. One is getting what you want, so you know how to get it. The second is wanting the right things, knowing what to want in the first place. I could want to be a 6'8" basketball player and I'm not going to get that. That's wanting something you can't get. But there's also wanting something that's a booby prize, prizes that are just not worth having, or that create their own problems." Naval explains how people end up in places they never meant to be: "If you're not careful, you can end up in a place in life not only that you don't want to be, but one you didn't even mean to get to. Usually people end up there because they're going on autopilot with societal expectations. Or out of guilt. Or out of mimetic desire, our desires are picked up from other people. Go to law school, go to med school, go to business school. Or it might be what your parents expect. Guilt is just society's voice speaking in your head so you'll be a good little monkey." He shares a problem most people have: "We run on these four-year cycles. You join a startup, you vest over four years. College is four years. High school is four years. You go to law school, that's a 5-year cycle. You become a lawyer, that's a 40-year cycle. These are very long cycles. But the amount of time we spend deciding what to do and who to do it with? Very short. We spend one month deciding on a job where we're going to be for 10 years." Naval's rule: "If you're making a four-year decision, spend a year thinking it through. Really thinking it through. 25% of the time." He explains the Secretary Theorem: "It turns out the optimal time to search is about a third. By a third of the way through, you've seen enough to know what the bar is. Then anybody who meets or exceeds that bar is good enough. But here's the key: it's not time-based. It's iteration-based. You need to take opportunities quickly and bail out quickly. If you look at failed relationships, the biggest regret is usually staying after you knew it was over." Naval reframes the 10,000 hour rule: "Malcolm Gladwell popularized 10,000 hours to mastery. I'd say it's actually 10,000 iterations to mastery. Iteration is not repetition. Repetition is doing the same thing over and over. Iteration is modifying it with learning and doing another version. That's error correction. If you get 10,000 error corrections in anything, you will be an expert." On pessimism vs. optimism: "You want to be skeptical about specific things, every specific opportunity is probably a fail. But you want to be optimistic in the general. Something in here is going to work out. If something fails, it was a learning experience. It was an iteration. As long as you learned something, it's a win. You don't want to jump into the first thing. But once you find the match, you have to be willing to go all in. Move your chips to the center of the table." He concludes: "Most people are stuck in this gray bit. 'I'm half in, but I don't really know.' That doesn't work. It's a barbell strategy, black or white. Explore quickly, cut losses fast. Then when you find the right thing, compound into it."
