🚀 Excited to share our #SIGGRAPH2025 paper: “Dynamic Mesh Processing on the GPU” 📍 Talk this week: s2025.conference-schedule.org/presentation/?… 📄 Paper: escholarship.org/uc/item/1sm051… 🛠 Docs and Code: ahdhn.github.io/RXMeshDocs/ We present a GPU system for dynamic triangle mesh processing with: 📐 Rapid mesh connectivity & attribute updates via patch-based, shared-memory design 🧠 Speculative processing for conflicts with cheap rollback 🕸️ A cavity operator unifying all dynamic mesh edits (collapse, split, flip) Performance: 🏎️ 10× faster than multi-threaded CPU 🚀 100× faster than single-threaded CPU 📈 Outperforms state-of-the-art GPU static data structures in speed & memory

Fuck it, we just made Fizzy completely free. The open source installable version was always free, but the SaaS version was pay. No more. Basecamp and HEY's largess will subsidize Fizzy for all. So go grab your account at Fizzy.do. It's Kanban the way it should be, not the way it has been. Fresh, fun, light, fast, and perfect for working with agents, too. An official CLI is coming soon as well. Stay tuned for that. The native iOS app should be out once Apple approves it (it's in approval right now...). Android is already out, you can get it on the Play store. (and BTW if you were a paying customer, you will no longer be charged moving forward)

@Love2Code @pikuma Wang Tiles: dl.acm.org/doi/abs/10.114…

@pikuma Is there a simple algo for making non-seamless textures tileable?

It looks like the Creator was lazy and did not implement seamless tiling texture.

@readswithravi Matt Dinniman - Dungeon Crawler Carl. The audiobooks are also fantastic.

Have you ever read a book by an author that was so good it made you want to read everything else they've written?

yep

@ThePrimeagen Watch this and get back to me youtu.be/5T_CqqjOPDc?si…

The Social Network is the single most important movie

Stewart Cheifet passed away, on December 28th, at the age of 87. Through The Computer Chronicles, Stewart inspired a generation of computer nerds (myself included). Back in 2017, Stewart was kind enough to sit down and chat with me. He was kind and amazing. May his memory be a blessing. youtu.be/PXCwjoPLU4c

It's DOOM’s 32nd birthday today! It amazes me how far this rebellion of a game has travelled. We wanted to build the the greatest game we could imagine playing, and generations of players have kept it alive. It’s one of the great privileges of my life.

@readswithravi Isaacson is a great all around biographer! I especially enjoyed “Einstein His Life and Universe”

Steve Jobs by Walter Isaacson is one of my favorite biographies of all time. QT with your favorite.

@readswithravi Consider: - Preferential attachement - Hanlon's razor

10 Concepts That Explain The Modern World: - Parkinson’s Law - Chesterton’s Fence - Law of Diminishing Returns - Pareto Principle (80/20 Rule) - Butterfly Effect - Tacitus Razor - Lindy Effect - Murphy’s Law - Dunning-Kruger Effect - Occam’s Razor What would you add to this?

@readswithravi The Four Agreements

Which book should everyone read at least once?

totally normal amount of cameras

@dhh I think it’s deeper than resumes. Look at, for example, Yahoo, Sun, Nokia, BlackBerry, and Twitter (pre-Musk).

"It takes ten years for the culture of a great company to fall apart once the CEO seat is given to someone without an engineering or product background. That's been the story of Boeing, Intel, and now Apple." world.hey.com/dhh/the-great-…

@readswithravi Yes 📚

Is there anyone else who still favors reading physical books over e-books?

Strap in nerds, we're going for a ride! Fast cars and fast operating systems pair beautifully together 😄

I agree companies can and do change. Satya’s Microsoft is a great example of that. But Apple shows the other side of the coin: when Tim Cook took over from Jobs, the company didn’t suddenly reinvent itself. Apple’s culture of integration and design runs deeply through the company. I think that makes abrupt shifts much harder. That stability can be good for consistency and focus, but it can also make adaptation slower.

@serban Company DNA changes all the time. Satya brought an entirely new vision and outlook to Microsoft. Despite having worked in the company for many years prior to ascending to the CEO spot. This is total present bias.

Apple's advantage is now all in the hardware. It might be impossible to imagine a MacBook free from the drag of macOS today, but Microsoft also centered everything around Windows until Ballmer left. Tim Cook will soon retire, and Apple will once more be able to think different!
