  • It’s a fine line, but it comes down to this: it’s not OK for the baker to refuse to bake a cake for someone in a protected class.

    However, it’s also not OK for someone in a protected class to compel speech from the baker.

    Ask the baker to bake a plain cake with no messaging on it: the baker can’t refuse on the basis of any protected attributes, like the customer’s race, etc.

    Ask the baker to decorate the cake with a “happy pride day” message? Only if the baker agrees to that expression. You can’t compel speech.

    It works the other way too: you can’t compel the baker to write something they disagree with if they don’t want to. It’s clear why a baker would be within their rights to refuse a “I’m glad all the Jews died” message on the cake. The baker is within their rights to decline any expression they don’t like. And that’s the way it should be.





  • I’ve recoded a bunch of x264 to AV1 and routinely gotten file sizes that are 10-15% of the original file size (a little more than 1/10th the original size)

    What I’ve found is that source content often has a lot of key frames. By dropping key frames down to one per 300 or one per 150 frames (one per 10 or 5 seconds for 30fps) and at scene changes, you can save a LOT of space with no loss of quality. You do give up the ability to skip to an arbitrary point in the content, however. You may have to wait a few seconds for rendering to display if you scroll to an arbitrary point in the content.

    If you’re just watching the content straight through, no issues. I set CRF to achieve 96 VMAF and I can’t tell any difference in quality between the content with that setup.

    I had one corpus of content that I reduced from 1.3 TB down to 250 GB after conversion.

    Unfortunately, only the most recent TVs have AV1 playback built in, and the current Fire sticks, Chromecast don’t have support for playback from a LAN source. I’m hoping the next crop of Chromecast and similar devices get full support, I’m assuming it’s just a matter of time until AV1 decoding is included in every hardware decoder since it’s royalyy-free.
