🚀 Excited to share our #SIGGRAPH2025 paper: “Dynamic Mesh Processing on the GPU”

📍 Talk this week: https://t.co/LGykTkFalj
📄 Paper: https://t.co/2UVIxV76tC
🛠 Docs and Code: https://t.co/gRPiYA6ccy

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

I’ve bought a lot of business books I never finished.

That’s why every one of mine uses a fable to convey the ideas.

I believe that for a leader, a finished, interesting book beats a comprehensive one every time.

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 https://t.co/pGxSDeGKNK. 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)

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.

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”

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