My website has previously been described as
"where the internet goes to die" and
"the virtual embodiment of a calling card scam" and
"detrimental to <my> career".

Despite these compliments, I felt it was time to make something slightly more useful: www.diwlevin.com

That’s the thing, now it has some value because LLMs need such a big data corpus. That multiplicity is what lets them learn a distribution. Now we can argue about how much value each nugget is worth (a lot to a little) but value it has.

I think it might also be a legal violation of the licences (IANAL). It would be fantastic if various government entities would grow a spine and enforce punitive financial penalties for this sort of thing, that get funnelled back to creators. Obviously the code has value and people should be paid.

the centralization of power is definitely a legit concern. I guess there major solution is don't use these tools. I'm wondering how you feel about a world where these coding agents are trained and run locally, rather than as a SAAS type model ?

for me it largely replaced cutting and pasting code off of stack overflow with a more efficient workflow. There's not substitute for thoroughly checking and debugging, but it helps me prototype ideas much faster.

I've wanted more of these types of papers forever in graphics. Benchmarks and evaluation are crucial in any mature field to help establish state-of-the-art. SCA 2026 is a great place to do that.

Reminds me of photo-ops where politicians visit a job site. Look they’re wearing a hard hat and holding a hammer, they understand !

Cynically I think all this is a weird teleopereration play … if you can have your workers remotely controlling your robot factory all of a sudden you can do a lot more outsourcing and avoid point of origin manufacturing restrictions.

Don’t worry spaceX is going to take all that IPO money and buy a million Optimus robots.

Abhishek Madan

My PhD student Abhishek Madan is getting ready to graduate and he’s looking for a postdoc or industry position. Checkout his website www.dgp.toronto.edu/~amadan/

He’s been an amazing student , basically does all his research by himself. Fantastic math and implementation acumen.

Realizing my follow up to this will likely be β€œwell all my submissions were rejected” 😬

For the first time in a while none of the SIGGRAPH papers I’ll submit have any ML (no neural nets no nothing) in them.

Why ?

The truth is that for most of my use cases those techniques have yet to show any practical benefit over good ol’ meshes and math.

It's funny to me that the SGP call for papers basically has all of SCA as a subtopic and I'm pretty sure SCA does the same thing in reverse.

It's like a snake eating its tail.

Sometimes using AI is productive, sometimes all that typing just makes you feel productive. And it’s really the feels that count.

Bonus points because you burnt down one rainforest to make this fire hydrant.

We are all just notation artists …

My PhD advisor was always testing creative hacks for math notation, from using colours to different typefaces to label quantities. I like using visually meaningful decorations (like tilde for deformed quantities because it looks like a squished bar).

Hey I made a new thing - it's called Gradientspace Graph, and it's a C#-based NodeGraph Programming system that also supports inline C# and Python "Code Nodes". The NodeGraph Engine is MIT Open-Source and the Editor is Free. More details here: www.gradientspace.com/tutorials/20...

The ACM Digital Library, where a LOT of computing-related research is published (I'd say at least 75% of my own publications), is now not only providing (without consent of the authors and without opt-in by readers) AI-generated summaries of papers, but they appear as the *default* over abstracts.
