Moving Quicksilver into production

One of the great arts of software engineering is making updates and improvements to working systems without taking them offline. For some systems this can be rather easy, spin up a new web server or load balancer, redirect traffic and you’re done. For other systems, such as the core distributed data store which keeps millions of websites online, it’s a bit more of a challenge. Quicksilver is the data store responsible for storing and distributing the billions of KV pairs…

Engineering Ethics Blog: Technology, Demography, and Destiny

  Most people, including most engineers, suspect there is some relationship between the advances in transportation, communications, sanitation, and health care brought about by modern science-based engineering on the one hand, and the tremendous and rapid growth in world population that has taken place since 1800 on the other hand, when there were only an estimated 1 billion people worldwide.  Now there are about 7 billion.  Something happened beginning a couple of hundred years ago that had never happened before…

The spirited songbirds can rapidly memorize the signature sounds of at least 50 different members of their flock — ScienceDaily

If songbirds could appear on “The Masked Singer” reality TV competition, zebra finches would likely steal the show. That’s because they can rapidly memorize the signature sounds of at least 50 different members of their flock, according to new research from the University of California, Berkeley. In findings recently published in the journal Science Advances, these boisterous, red-beaked songbirds, known as zebra finches, have been shown to pick one another out of a crowd (or flock) based on a particular…
