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 an Android Pie Update: the Picture Message Preview is a Paradigm Shift

On Android Pie, there is a Messages app feature, and this app has a native picture preview.  Today, on Android Pie, I captured a camera picture. Then, I received a notification. On my Android Pie phone, the notification was a drop-down, and it had a small picture. After selecting the notification down arrowhead, a middle-sized picture preview displayed. After I had waited three-plus seconds, the message picture notification disappeared. On the drop-down menu, there was a small picture  preview. On the Messages app was a large picture preview. On Android Pie, the Messages app reduced overhead because it caused less file search reliance, and less sort reliance. For an average search example, the binary search tree requires O(n) search time because it one step, and I have the datem. For example,  the average Selection Sort requires O(n^2) time complexity because two a computer selects the datem then sorts the datem. For more asymptotic notations, review Eric D. Row
