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

How Control Theory Can Help Us Control COVID-19

On Spotify, listen to my related podcast: link   COVID-19 On 17 April, 2020, 5:00 AM Chicago, IL time, Greg Stewart, Klaske van Heusden, and Guy A. Dumont released the IEEE SPECTRUM article How Control Theory Can Help Us Control COVID-19 ( link ). Stewart, et. al. wrote, “As we write these words, several billion people, the majority of the world’s population, are confined to their homes or subject to physical-distancing policies in an attempt to contain on of the worst pandemics of modern times” (Stewart, Heusden, Dumont, 17 Apr, 2020). This is a reflection against the COVID-19 pandemic’s recorded measures. The Reproduction Number of COVID-19 Against other recent disease outbreaks, Stewart, et. al. wrote that the COVID-19 pandemic is unique: the reproduction number, or Ro (“R naught”), that is, the infection rate per infected person during infection. The Cost of Easing Social-Distancing Restrictions About easing social-distancing standardization, Stewart, et. al. wrote a commonly cited

Information, Technology, and the Virtues of Ignorance

Information Technology and Ignorance In 1986 AD, Daniel C. Dennett wrote Information, Technology, and the Virtues of Ignorance ( link ). When Dennett was ten years old, he read Robinson Crusoe. When Dennett read Robinson Crusoe, he loved technology. Dennett loved technology so much: Dennett claimed technology is good; Dennett did not rationalize his devotions. Dennett stated we control technology unlike magic. Dennett claimed that technology that exists: is true. Dennett claimed his technology is convenient, for its blessings: his technology group has received provisions. Put an end to Tradition Against troubling technology traits, Dennett gave a proposition. Dennett claimed: his peers should leave tradition behind, or else information technology can ruin his peers' and his lives. Dennett believed we all want our lives good. Dennett stated: we want lead lives interesting. Also, Dennett stated we want lead lives good. Dennett described these things useful and a right difference. Nex
