my brain at 3am: 6 hours of sleep is plenty, I'm finely exhausted enough to stop comfy-cool

my brain at 9 am after drinking coffee: lets-fucking-go

my brain at noon: STOP BOTHERING ME ASSHOLE! maddened

Doing their best to play dumb, but it's plain to see they knew what "against the Russians in WW2" means.

Women below 50 have a more positive view of socialism over capitalism. They just need a bit more theory to bring down the communist red flag numbers.

brainworms run deep.

Liberalism : Anti-Socialist :: Socialism : Anti-Capitalist

Interesting stuff.

Why does piracy need a business model? Sci-hub etc already exists.

This seems more like just a reality of LCD / LED display tech than anything. CRTs (remember those?) can do a lot of resolutions pretty well no problem, but new stuff not so much. I remember using a lower rez on early LCDs as a 'free AA' effect before AA got better/cheaper. This just seems like a response to folks getting ~4k or similar high rez displays and gfx card performance unable to keep up.

I was just playing around with gamescope that allows for this kind of scaling stuff (linux with AMD gfx). Seems kinda cool, but not exactly a killer feature type thing. It's very similar to the reprojection algos used for VR.

Then who makes the coprocessor that is inserted into the die?

Looking into more details of the boot process, it seems like the UEFI manufacturers such as AMI or Phoenix might be the best place to insert a pre-OS boot back door. The PSP (CCP) is just what is used to bootstrap before this step in the process.

https://en.m.wikipedia.org/wiki/AMD_Platform_Security_Processor

The PSP itself represents an ARM core (ARM Cortex A5[6][circular reference]) with the TrustZone extension which is inserted into the main CPU die as a coprocessor. The PSP contains on-chip firmware which is responsible for verifying the SPI ROM and loading off-chip firmware from it.

Critics worry it can be used as a backdoor and is a security concern.[3][4][5] AMD has denied requests to open source the code that runs on the PSP.

The PSP also provides a random number generator for the RDRAND instruction[10] and provides TPM services.

The Cavium stuff mentioning RNGs being compromised reminded me about this recent headline about fTPM RNG being wonky on some AMD motherboards.

Probably not related, right? I wonder who the fTPM manufacture is for these boards.
