CONTEMPORARY REMINDER. “A new flaw has been discovered in the computer system for the Boeing 737 Max that could push the plane downward, according to two sources familiar with the testing, an issue that is expected to further delay the aircraft's return to service.” https://lnkd.in/d5ytNit View in LinkedIn

DIGITAL INFORMATION ROOT. "Software is stored in the hardware as magnetic domains on the hard drive or floppy disc, or as low and high voltages in computer chips. When you type on a keyboard, each character is converted into an electrical series of 0's and 1's which are then stored as low and high voltages in the computer chips called RAM." https://lnkd.in/d-JGnVK View in LinkedIn

THE INFINITE POSSIBILITY. "While today’s computers politely use programmed instructions to solve predictable problems, these adaptable alternatives may one day strip away such limits and lay bare the elegant solutions that the human mind is reluctant— or powerless— to conceive on its own." https://lnkd.in/d-JGnVK View in LinkedIn

INCOMPREHENSIBLE SYSTEMS. “There is concern that a dormant “gene” in a medical system or flight control program might express itself without warning, sending the mutant software on an unpredictable rampage. Similarly, poorly defined criteria might allow a self-adapting system to explore dangerous options in its single-minded thrust towards efficiency, placing human lives in peril." https://lnkd.in/e5p4fXs View in LinkedIn

STANDARD DISTRIBUTION CURVE OF ERRORS. "The standard evolutionary picture tells us that evolution is messy, incomplete and inefficient." https://lnkd.in/dycehf5 View in LinkedIn

THWARTED PATHS. "It is not difficult to imagine that coevolution might sometimes block certain adaptive paths." http://rspb.royalsocietypublishing.org/content/royprsb/283/1839/20161528.full.pdf View in LinkedIn

PERSISTENCE. "Dynamic polymorphisms involve fluctuations in allele frequencies caused by selection and are inherently persistent, although fixation can occur as a result of genetic drift." https://lnkd.in/d3-W8NW View in LinkedIn

HOST SMOKE SCREEN. "We demonstrated how the host’s coevolution led to varied, and sometimes even opposite, effects on the relative fitness of different virus genotypes." http://rspb.royalsocietypublishing.org/content/royprsb/283/1839/20161528.full.pdf View in LinkedIn

MOVING TARGET. "Improvements in adsorption were offset, in large part, by the evolution of host resistance, which occurred by reduced expression of LamB, the usual receptor for l. As a consequence of host coevolution, the adaptive landscape of the virus changed such that selection favouring four of the six virus intermediates became stronger after the host evolved resistance, thereby accelerating virus populations along the path to using the new OmpF receptor." http://rspb.royalsocietypublishing.org/content/royprsb/283/1839/20161528.full.pdf View in LinkedIn

INTERMEDIATE GENEALOGIES. "Here, we examine how this innovation evolved by studying six intermediate genotypes of l isolated during independent transitions to exploit OmpF and comparing them to their ancestor. All six intermediates showed large increases in their adsorption rates on the ancestral host." http://rspb.royalsocietypublishing.org/content/royprsb/283/1839/20161528.full.pdf View in LinkedIn
