.and a CPU+GPU that can generate a full frame of AAA graphics in under 1 msec. Good luck w that. Same thing with apples "retina" displays. Yeah they are nice to look at.. but it's REALLY hard to feed a high res image at any decent framerate.

Doubling the frame size means quadrupling the GPU framebuffer size = 4x more horsepower to feed it.

The content is accurate, the opinion is based on the findings and additional inputs.

The less third parties you have the better the opsec.

Messaging apps also get cam/mic/location/contacts permissions, Signal is no different, one more entity with your face/voice/place/friends.

You are free to keep using Signal, but trusting a third party messenger is really, really risky.

Agree to disagree.

There's more to PVs than just the panel itself. It's also the manufacturing and nighttime electricity storage. This is non-marginal when PV manufacturing is dirtier and riskier than combustion engineering, because boilers don't require special acids to be made. At least not on a simple level. The larger supply chain needs to be addressed, regardless of how much wishful thinking currently happens most PVs are still made in China and most are made in appalling, dirty conditions that actively contribute to global warming & thus represent an external climate cost to PVs as even the best PVs don't last more than 25 years. Gen 1 PVs are already hitting their end-of-life and most are being landfilled in Asia, contributing to the global microplastics problem.

This doesn't discredit PVs as a technology, but it does discredit neoliberal capitalism as a means to deliver it. We need to stop importing energy, including manufactured energy devices such as PVs and electronics in general.
