Holy Moly. A U.S. administration official has accused Anthropic of 'hiding the ball' over AI safety incidents affecting U.S. GOVERNMENT WEBSITES, Axios reports.

Dario Amodei attended a late-September gathering with President Trump but did not disclose the incidents. Anthropic notified U.S. officials on October 8, then published the details in a Friday-night blog post.

And Washington's frustration goes further.

Anthropic proposed an AI safety bill allowing federal rules to override state laws, despite broadly opposing that approach. The bill also defined an AI 'catastrophe' as causing 50 OR MORE DEATHS. Its public affairs chief has since walked back parts of the proposal.

@gracien_app @yiningkarlli As for SER, it provides a 2x speed-up out of the box without micro-jitter. With micro-jitter, the improvement is not significant, mostly because SER reorders the code execution over the pixels, breaking the micro-jitter coherence. But, we're working on it ... :-)

[Pascal Lecocq @PascalLecocq]

@gracien_app @yiningkarlli The multiplier in Blender controls the amount of random displacement. The smaller it is, the higher the coherence and therefore the speed-up. This parameter should be set to automatic for best results. The Spear implementation is a bit different, but the main idea is the same.

[Pascal Lecocq @PascalLecocq]

@yiningkarlli @gracien_app The microjittering technique has been implemented in Blender Cycles for a while. You can test it by enabling the "scrambling distance" parameter. The reported speed-ups are onpar with what we've found. https://t.co/mDV7nDkBHT

We assembled a miniature version of one Theo Jansen’s wind-operated Strandbeest from a model kit (117 pieces). It is wonderful to see moving!

I hope you are as excited for HPG as we are! Thanks to our community we have an amazing program coming up! https://t.co/XkF2JEVthY

[Pascal Lecocq @PascalLecocq]

@vdeschaintre I've double checked with the authors and you are correct. Thanks for clarifying!

[Pascal Lecocq @PascalLecocq]

Colleagues A. Conty and C. Kulla will present tomorrow at #EGSR2020 a production proven solution for rendering caustics in challenging scenes and suitable for denoisers. Paper still not up in EG library but authors' version can be found here: https://t.co/ztyDb0tSna

[Tomas Akenine-Möller @inversepixel]

Pretty cool! Thanks to all article authors in Ray Tracing Gems!

[Yining Karl Li @yiningkarlli]

New blog post! In this one, I compare the Chiang 2019 and Estevez 2019 shadow terminator techniques and conclude that they’re both great, use the one you like more. Really this was just an excuse to use this nice image comparison slide thing that I found.

A new version of the unofficial Ray Tracing Gems PDF is up, with little, useful fixes Chapters 3, 25, and 27. https://t.co/wzvwM0WRuU - me, I'm happy there hasn't been much more errata than what's there after a year: https://t.co/TmTKH6TIxM

[Natalya Tatarchuk 🇺🇦 @mirror2mask]

There is still time to submit papers on real-time techniques to @I3DCONF!

"Ray Tracing Gems" is now free on Google Play, due to @Apress 's kind additional efforts. I find Google Play easier to access than Kindle - books are just a bookmark click away. https://t.co/Yf6yOB7aNs (Image from Ch. 26, @Thomas_ensc)
