Plasma strips on wings cut drag 74% & viscous drag 62-80% with 1100% power savings (more speed = more gain). No need to cover whole plane just spot them smartly. Hypersonic flight tests (Mach 3-8) coming 2027 Ex: (NY→London in 90 min) without exotic engines.36hr+ drone patrol

Wow. Recreating the Shawshank Redemption prison in 3D from a single video, in real time (!) Just read the MASt3R-SLAM paper and it's pretty neat. These folks basically built a real-time dense SLAM system on top of MASt3R, which is a transformer-based neural network that can do 3d reconstruction and localization from uncalibrated image pairs. The cool part is they don't need a fixed camera model -- it just works with arbitrary cameras -- think different focal lengths, sensor sizes, even handling zooming in video (FMV drone video anyone?!). If you've done photogrammetry or played with NeRFs you know that is a HUGE deal. They've solved some tricky problems like efficient point matching and tracking, plus they've figured out how to fuse point clouds and handle loop closures in real-time. Their system runs at about 15 FPS on a 4090 and produces both camera poses and dense geometry. When they know the camera calibration, they get SOTA results across several benchmarks, but even without calibration, they still perform well. What's interesting is the approach -- most recent SLAM work has built on DROID-SLAM's architecture, but these folks went a different direction by leveraging a strong 3D reconstruction prior. Seems to give them more coherent geometry, which makes sense since that's what MASt3R was designed for. For anyone who cares about monocular SLAM and 3D reconstruction, this feels like a significant step toward plug-and-play dense SLAM without calibration headaches -- perfect for drones, robots, AR/VR -- the works!

@levelsio You can use the Apple or intel depth model to build and project the visible areas of the room from the image. Works in three.js. The quality degrades on the areas of the room that aren’t in the image, but I think that’s what you’re trying to fix here.

Tried a cube map Kinda works, perspective a bit F'd But proof of concept of moving camera left/right, no less :D

@gplama SysPromt even puts the Grok summary to shame. It must have internally generated a poem and analysed it as reality 🤓

So I was duped while trying to be helpful. Someone asked for advice on bike tech, I reply, their follow-up reply was suspicious. Something didn't seem right. It only took a few minutes to nail down who was playing me. reddit.com/r/cycling/comm… (Expand all comments over there)

@Retlouping Possibly muscle overuse or strain, exacerbated by excessive post event IG and X scrolling during travel. Chest muscle tension from event leading to forward shoulder posture. Possible RSI.

@eevblog But how long will it take 100 machines to produce 100 parts?

AI startups actually have a very strong moat we simply refer to it as "python virtual environment" and "cuda version" most of your competitors will give up before they get past this step

@boyntoncoaching @JeroenSwart @D_Blodgett Do the study Jason. I’d say the answer would be something like; increasing glycogen storage through high torque training delivers improvement in global cycling performance. physoc.onlinelibrary.wiley.com/doi/pdf/10.111… Get one of these and I’ll let you test on me 😁 doi.org/10.3390/nu1204…

@JeroenSwart @D_Blodgett This is a red herring, @JeroenSwart. I never said every training decision has to be based on the literature. Again, my issue is stating something is "fundamental" to endurance training when the evidence is nothing more than reasoning and anecdotes.

Such a fundamental part of training. I have watched numerous World Tour riders set new PBs for power after completing a good block of torque work where they have achieved PB for torque. It’s the foundation for producing power.

@Noahpinion @ImpulseLabs_ I’m guessing you haven’t attempted to purchase batteries on a commercial scale lately? 🫠

I think battery-powered appliances are going to make a big difference for the fight against climate change. I invested in a company, @ImpulseLabs_, that is pushing the boundaries of this technology! noahpinion.substack.com/p/battery-powe…

@Alan_Couzens @fasttalklabs Fantastic. I always thought a metric along the lines of “Maximal rate of heart rate change” from within a session would go a long way to describing fatigue status. Maybe adding it as a hash to your system could help! 🙂 researchgate.net/publication/28…

@MichaelFreiberg @fasttalklabs Thanks! Not too mind-bending but definitely an initial challenge since my athletes data's on TP & they don't have an API. Worked out a solution, though Yes, I use LSTM's to account for different dose-time-response relationships, both different athlete & different training types

It's crazy just how slow endurance sports have been in implementing new better #AI models in the training process. Sadly, we've regressed from Banister's papers back in the 1970's! Here I chat with @fasttalklabs about the next step.. #NeuralNetworks fasttalklabs.com/fast-talk/neur…

@Alan_Couzens @fasttalklabs Wow, yes, of course. It seems like you have built a mind bending preprocessing pipeline to extract the relevant data for the network. I feel that would be the hardest part! Well done! Have you considered using LSTM or Embargo CV to allow for time series effects?

@MichaelFreiberg @fasttalklabs Why would it read submax data as if it were maximal? That's one of the big advantages of the NN as opposed to a 2 factor dose-response model - we can feed it independent power and HR data, so it 'knows' when it's a submaximal effort.

@N_Squillari 66 comments suggests the article was a hit and generated great advertising profits! Expect to see more like it 💰 💰 💰 😉

the piece in question cyclingtips.com/2022/07/is-the…

What's the state of play for a Streisand Effect article about celebrity partners at the Femmes Tour de France? And then calling opposition to the piece "toxic male energy" Celebs at other sporting events are nothing new. Partners, certainly more rare. How is this bad? Or 'toxic'?

Fantastic 🤓

@peter__leo Thanks Leo. That was a fun blog to write. 🙂
