Spectre and Meltdown Explained, and a Proposed Counter Against Them

On January 15, 2018, 2:58 AM PST, Josh Fruhlinger wrote Spectre and Meltdown explained: What they are, how they work, what’s at risk . As threats, regarding these two risks, Spectre and Meltdown, Fruhlinger wrote, “In the first days of 2018, published research revealed that nearly ever computer chip manufactured in the last 20 years contains fundamental security flaws, with specific variations on those flaws being dubbed Spectre and Meltdown ” (Fruhlinger, Jan 15, 2018). Fruhlinger was stating this: despite the best known efforts Electrical Engineers and Computer Scientists exercised, computer chip technology dated 1998 AD - 2018 AD has experienced an error, design flaws, that led to known defects, Spectre and Meltdown, and these are potentially great failures.  Side-channel technology requires high grade technical research, and this can be because Spectre and Meltdown exist, so a layman would not have known it, 22 years ago. According to Josh Fruhlinger, speculative execution and cac

On Neuromorphic Chips: Advanced AI, Deep Learning, and Neural Network Computer Architecture

Neuromorphic Chips to Become Affordable In the August 2020 edition of Communications of the ACM , West Linn, OR, USA-based author and journalist, Samuel Greengard, wrote Neuromorphic Chips Take Shape . The available data Greengard had is the claim that a Caltech (The California Institute of Technology) professor invented this technology, neuromorphic chips. Greengard wrote, “The concept of a brain-like computing architecture, conceived in the late 1980s by California Institute of Technology professor Carver Mead, is suddenly taking shape” (Greengard, Aug 2020, p. 9). Since the date, today, is around forty years later, this technology has remained dormant, but not in the research, thus so recent advancements probably allowed neuromorphic chips to become affordable (With LTE capabilities, see current pricing of a standard productivity PC, an i5 Microsoft Surface Pro: ( link ). With 3G capabilities, alternatively see the current pricing of a legacy, but GPU intensive PlayStation Vita: (
