This is worse than scripted "clapter" comedy, which is just designed to further an agenda.

Last time I was in China it struck me that my secure VPN solutions, using my own tunnels and pre-installed keys etc, they never worked well. They are throttled to death after a very quick time, since the firewall does not recognize the traffic.

Meanwhile, the VPN solutions my Chinese colleagues use seem to work very well, and it's an open secret. Everyone uses them.

This makes me pretty certain that every VPN solution that works within China, they work simply because there is a known backdoor.

Wikipedia has the gory details, complete with citations. My opinion is that the Donkey Kong and Pac-Man scores from the eighties are likely genuine and that's why he held the world records, not hold them.

Everything from his "comeback" this millennium should be taken with a truckload of salt. Some of it has of course been formally debunked and retracted.

Imagine if this argument was used in drug policy discussions.

"Some people are addicted, they need drugs, it would be cruel to ban drugs"

Yeah, those in "need" of expensive credit are probably those who should not have access to it.

I'm explicitly not talking about storing this in JPEG - it's even mentioned as an example of other formats.

But every format that does compression - even lossless - performs a number of transforms in every dimension, spatial, spectral etc. It's to make it easier to locate redundant information. If the transform and compression is reversible (for example delta-encoding neighbouring pixels and run-length coding), it's lossless.

Transforming the channels with something like a principal component analysis would losslessly transform all the channels into something that could more easily be compressed without loss.

That's weird, why wasn't this already standard practice?

The idea of collecting the energy from multiple layers like DSP 101, I first read about it in graphics literature from the early nineties when I started, and multi-spectral images in astronomy is the standard example of where this is useful.

Of course JPEG and many other related formats already do this with the RGB layers but with a hardcoded transform designed as a decent compromise between image perception and being easy to calculate.

That's actually an interesting question.

As many of us, I remember a time before there were any useful search engines.

We largely survived on our personal collections of links, "web rings", and other topical link collections.

I don't know if that would have made a difference. I know full well what a nanometer is and what a micrometer is. The demo shows a display that's 3-4 cm wide, with a pixel count in the hundreds. There's no confusion about the units.

My old Pixel 7a has 60 micrometer wide pixels, what's the point of this "demo"?

This is nothing but an ad for a specific brand of phones.

Everyone has a "three year roadmap", it's always three years in the future because that's when everyone has forgotten the empty promises. They have nothing to back this up, other than "we will add more battery".
