The less likely engineers are to review their own commits with LLMs, the more they rely on empirical measurements for it, the more useful Data-Oriented Programming becomes. Easy to adopt, not a huge challenge to maintain.
Had an opportunity to present another generation of engineers to @mike_acton 's "Data Oriented Programming" CPPCON 2014 talk, and saw the wheels in their brain start to turn. The talk is still relevant, and far easier to act on with LLM-assisted coding.
It's official: the original Black Ops and Black Ops 2 are being ported to PlayStation in July, courtesy of our partners at @IronGalaxy. 🤝

@SebAaltonen What I do if I need to decrease the time a little (if I need a lot of time then I sadly cut actual content). It only works if you stick to speaker notes for your speaking during the talk. I don’t cut slides, I trim what I say in each slide to a more concise message.

@g_Schellenbaum I don’t disagree with anything you’ve written. Until we have a better model then all these things are worth doing. Separately from that, I have a strong feeling that a better model is out there and we should be spending more effort on finding it.
This might be the most important paper on surface shading to come out in years. TL;DR: microfacet models are wrong and proposed wave-based or hybrid alternatives are wrong too. This is an exciting opportunity for new research! ssteinberg.xyz/2026/04/01/acc…
@tonyblu331 @g_Schellenbaum I meant the directional error term specifically - it only works when you have a massive calibrated database of photo references to analyze. It’s not the kind of thing that an artist could paint from scratch when creating a surface from a concept sketch.
@g_Schellenbaum TCP is a great example of a practical production solution. But it doesn’t replace the need for a model which is robust, artist-controllable and *also* (unlike current models) matches the real world; if anything it shows the need for such a model.
Instead of “are wrong” I should have said “are a poor match to real-world surfaces”. As George E. P. Box taught us, all models are wrong anyway 🙂
