Brainstorming some solutions. Maybe a randomized algorithm for ECC. Every so often changes how the ECC is computed? The region nearby where privileged information is stored could have a speed limit on multiple sequential writes? Add blocks

I was talking about previous iterations of facial SR. After the white Obama debacle, researches included skin color as one of the parameters in the cost function.

Those old face super resolution cnn were usually trained with the celebA dataset. And because celebs have above average attractiveness, so did the generated images. Also the dataset were primarly white. Creating the meme image white Obama.

Using AVX 512 is not suitable for programs that takes very small time to run. There is a penalty in the ms range to "warm up" the CPU (it is more a cool down, actually). As OP stated, the limiting factor is on the memory access. T

Modern x86 CPUs have micro instr caches to store small loops (about 50 instr) and medium loops (~2k instr). Also, the bottleneck is usually the instruction decoding (Alder Lake made huge changes on that, so this might change). In other word

The FAA NORAD tapes from 9/11 is available on YouTube. I found it shocking how unprepared everyone seemed to be. I'm reading the Vanity Fair article, it adds context missing from the raw communication. It helps to understand why i

Cloroquine and ivemerctin used to be a suggested treatment on the official government website. Nowadays they are saying "the site was hacked" -- the content wasn't suppose to be publicly available.

I think you are spot on. Just want to add that the content consumption was also hindered by the technology. Fun Fact: Vine was created in the same year the first CNN completed ImageNet with (much) higher accuracy than others contestants.

You can use formal verification tools to verify the code. Having preconditions ("assume" instead of "assert") reduces the search space.

I'm not sure if this apply for human genome, but virus like covid compress many protein in the same sequence. The ribosome iterates over the same genes, starting each new iteration at i+1. This process runs a finite amount of times, pr

It is hard to compare efficacy between different vaccines trials sinc each one was tested in different populations. For instance, Sinovac vaccine was tested in hospital workers in Brazil. This population is more exposed to the virus and hav

Brazil sent data to Sinovac in December, before the surge of cases of P1 VOC. Also, most cases of the new variant are in the north of the country. AFAIK, Sinovac vaccine was not tested there.

They used a similar reasoning as OP. The huge increase on hospitalization in this month suggests heard imunity might not be possible. Either due reinfection, either because a more agressive variant is infecting people not yet imune. Reports

It's seems the author didn't review previous literature on heard imunity on covid. For instance, Manaus had 76% of serumprevalence in October and the number of new cases seem stable. Fast Forward to this week, the health system co
