The new block cluster shared memory and synchronisation stuff looks really really nice.

Ambient occlusion is a horrible hack from twenty years ago. You don’t need to measure pixel values from photographs to know that it bears no relation to how light works in the real world. Just don’t use it.

That’s because nvidia hired like every graphics researcher.

Men are more likely to die of COVID and more likely to be intubated. Should we start preferentially treating men over women? Why did they not include this advice as well?

And there are hundreds of thousands of children under 12 who aren’t vaccinated.

Lol “draconian measures”. Yep we’re all under house arrest down here it’s awful. Basically the same as Stalin’s Russia.

You said:

> Do you support denying re-entry to people who are already citizens as a means of doing that?

Which implies the people entering on these visas are taking places away from someone else but they’re not, they’re entering the same lottery system as everyone else. Unless you’re suggesting that only citizens should be allowed to enter the country?

A few weeks ago everyone was expecting them to replace MIQ with home self-isolation in Feb-April thanks to the vaccine uptake. Now Omicron has thrown that all up in the air.

What about people who can’t take the vaccine for medical reasons, or are too young? Fuck ‘em right?

This isn’t what’s happening. Everyone trying to enter the country has to go through the MIQ system, regardless of whether they’re a citizen, have one of these visas, or any other type of visa.

Yes it is a good deal. This is manufactured outrage.

On a similar note - if a huge gravity wave passed through the earth, say one that stretched the space I’m in by a factor of 10, would I feel anything?

See comment elsewhere in this thread for how smoking is a massive net gain for the UK government thanks to high taxes and early mortality.

New comment by pixel_fcker in "Monoio – A thread-per-core Rust async runtime with io_uring"

pixel_fcker — Thu, 09 Dec 2021 18:13:06 +0000

It sort of goes against Rust’s philosophy to bake anything like that into the language.

Where they screwed up was not providing the machinery to make libraries agnostic of the runtime an end user wants to use in their program, so libraries either depend on a specific runtime explicitly or use features to allow users to switch runtimes at compile time. This causes a lot of headaches for library maintainers and end users both.

There’s a lot of interest in adding said machinery (through collections of traits in std) to enable libraries to be generic over different runtimes, but a solution is still some ways off.

It will if the output is expecting RGB in Rec.2020 or P3 and you give it sRGB data…

AP1 is essentially Rec.2020, yes.

By working space I mean a space in which a user manipulates the data in some way, e.g. image editing, grading, compositing or rendering.

ACES (AP0) is an archive format for when you want to be absolutely sure you’re not clipping any colours. As a working space it’s terrible and AP1 should be preferred, either as ACEScg or ACEScc

There are several companies offering this out there. ILM definitely doesn’t have it “locked up”.

VFX companies don’t own any of the assets that they create for films, the studio does. I don’t know what Unity think they’ve bought there.
