The best way to predict the future… is to build it with an amazing community of like minded innovators - who are dissatisfied with the status quo.
A powerful idea from @stephen_wolfram: The physics you observe depends on how you are constructed as an observer.
New paper on arXiv! And I think it's a good'un 😄 Meet the new Lattice Random Walk (LRW) discretisation for SDEs. It’s radically different from traditional methods like Euler-Maruyama (EM) in that each iteration can only move in discrete steps {-δₓ, 0, δₓ}.
Thank you Frank! Really appreciate all the support from you and the committee, and all my friends!
Very happy to announce that my PhD student Fan Jiang (@FanOnRobotics) successfully defended yesterday, on "Inertially-Aided Navigation with Ultra-Wideband Wireless Ranging". Fan did some cool work with factor graphs and also built a rust-powered UWB ranging device in the process.
Over the long weekend I managed to get Godot 4.4 running on the Vision Pro using the brand-new Metal rendering pipeline!!! Right now, it’s rendering only. Next steps Head/Hands tracking. #GodotEngine #AppleVisionPro #gamedev
Wow Swift is on HN again! "Swift is a more convenient Rust" news.ycombinator.com/item?id=414643… I really like Swift's ergonomics over Rust but the (current) cons of Swift: 1. the lack of non-Apple community 2. "no_std" is an afterthought 3. Unnecessary gardening of UI-related stuff to AAPL
I regretfully completely understand Wedson's frustrations. lore.kernel.org/lkml/202408282… A subset of C kernel developers just seem determined to make the lives of the Rust maintainers as difficult as possible. They don't see Rust as having value and would rather it just goes away.
BTW I encourage anyone who wants something different to come help us make requwest / object_store better (if you want to use a different runtime, come on and help us make it work 🎣)
We've been evaluating a number of C++ successor languages for @ladybirdbrowser, and the one best suited to our needs appears to be @SwiftLang 🪶 Over the last few months, I've asked a bunch of folks to pick some little part of our project and try rewriting it in the different…
However, there is a way to bound the growth of a harmonic function, using so called "Harnack estimates" from PDE theory: en.wikipedia.org/wiki/Harnack%2… The basic idea is that, within a ball, you can find a function that grows faster than *any* harmonic function. [19/n]

Signed distance functions (SDFs) are an important surface representation, which can be directly visualized via the “sphere tracing” algorithm. At #SIGGRAPH2024 we showed how to sphere trace a whole new class of surfaces, based on *harmonic functions* rather than SDFs. [1/n]

A wrote a book on how debuggers work! It guides you through writing a complete native debugger from scratch. Available Spring 2025 from @nostarch (probably not with this cover)
Ask X: Is there a good embedded ROS/ROS2 library in Rust/C++? micro-ROS is just a huge pile of unmaintained code and broken as hell. 😢😢😢
✨Some shiny new Pallas features in @PyTorch XLA 2.4, including support for Flash Attention and Paged Attention: cloud.google.com/blog/products/… (PaigedAttention = activated! 😁)

TIL: Don't buy ZED cameras for multi-sensor research, they don't have external sync input/output...
Wow that's right. This was a big day and Swift has come a long way in the intervening decade: Congrats to everyone who has driven it forward to support such an amazing tech platform! 🍎🐣
omg, the hidden variable resultant method! Also seen in the 5-point camera pose estimation problem in "Five-Point Motion Estimation Made Easy", ICPR'06 by Hongdong Li and Richard Hartley.
I forgot about the secret message I left in my website about responding like the Swedish Chef. I did it 9 months ago. I've never been able to trigger it before. Thank you Perplexity AI.
