Carl Sagan is one of my heroes, extraterrestrial life would be really cool to find, so of course this item interests me. Not so much you? Oh well. "The conversation touched on some the big questions you might expect: the compatibility between science and religion; the probability we’ll encounter extraterrestrials if given enough time; and more."
These are some good lessons; here they are, with some comments from me:
Good article, worth the read.
People are talking about 'microlearning' again. Today's learners, writes , "are equipped to research what they need to know and learn about it from various sources such as blogs, online courses, websites or YouTube videos." This, mocrolearning. "Microlearning is a method to teach and deliver educational content through short and concise segments that cover focused topics while fulfilling specific objectives." Try to ignore the hype and sensationalism (like, for example, "...has caused the attention span to fall to eight seconds (eight!)" or the broad over-generalizations about "millennials"). The main thing is to take the concept seriously, and maybe follow some of the links for more detail.
Some tereminology from Elliott Masie: "we are seeing more 'Stacking', which means accepting the role of the existing LMS as the base system for the organization and then adding Stacks or Layers on top that will create added and more targeted functionality... In other words, some organizations are shifting from replacing their LMS to adding these technologies on top of the LMS. Some may be limited to a specific line of business or segment of learners. Others are layered in almost as extensions of the LMS." No links, and not much content beyond this (because it's Masie) but I wanted to make sure I shared at least this.
Useful and clearly explained description of how VPNs and proxies differ, and what they're best used for. With a proxy, you simply route your internet traffic through another server; there is no encryption, but it hides where your original request is coming from. A VPN, on the other hand, will encrypt the traffic between you and that second server. "In summary, proxies are great for hiding your identity during trivial tasks (like “sneaking” into another country to watch a sports match) but when it comes to more series tasks (like protecting yourself from snooping) you need a VPN."
