Anti-disinformation research There was a meetup regarding disinformation at Wikimania 2019 <https://wikimania.wikimedia.org/wiki/2019:Meetups/Disinformation>. Thanks to Leila <https://wikimania.wikimedia.org/wiki/User:LZia_(WMF)> for the notes from the session. I am glad that that there is interest among WMF and community members regarding this topic. Humor "The trouble with quotes on the Internet is that you can never know if they are genuine." —Abraham Lincoln <https://www.pinterest.com/pin/360921357612301545/> (For anyone who does not understand the joke: Abraham Lincoln’s life preceded the existence of the Internet by approximately a century.)

Content August 1877, “American astronomer Asaph Hall discovered Phobos, the larger of Mars's two moons, six days after his discovering Deimos, the smaller one.” This image of Phobos is featured on Commons and on the Arabic, English, Spanish, and Persian Wikipedias <https://commons.wikimedia.org/wiki/File:Phobos_colour_2008.jpg>. I enjoyed reading the description of how the image was made. Also of note is that when Asaph Hall was learning mathematics, he studied under an instructor who was two years ahead of him, Angeline Stickney. “During their days together as teacher and student, Hall and his classmates would devise questions and problems that they were convinced Miss Stickney could not solve, yet she never failed to solve them <https://maia.usno.navy.mil/women_history/hall.html>.” The two of them later married. Stickney encouraged Hall to search for the Martian moons. Hall said, "The chance of finding a satellite appeared to be very slight, so that I might have abandoned the search had it not been for the encouragement of my wife." The largest crater on Phobos <https://en.wikipedia.org/wiki/Stickney_(crater)> is named Stickney in her honor. The Commons Picture of the Day for 23 August 2019 was “Khotyn Fortress under the light of the full moon <https://commons.wikimedia.org/wiki/File:%D0%A5%D0%BE%D1%82%D0%B8%D0%BD%D1%81%D1%8C%D0%BA%D0%B0_%D1%84%D0%BE%D1%80%D1%82%D0%B5%D1%86%D1%8F_%D0%B2_%D0%BC%D1%96%D1%81%D1%8F%D1%87%D0%BD%D1%83_%D0%BD%D1%96%D1%87.jpg>”. According to the article about the fortress on English Wikipedia <https://en.wikipedia.org/wiki/Khotyn_Fortress>, “The Khotyn Fortress ( Ukrainian <https://en.wikipedia.org/wiki/Ukrainian_language>: Хотинська фортеця...) is a fortification complex located on the right bank of the Dniester <https://en.wikipedia.org/wiki/Dniester> River in Khotyn <https://en.wikipedia.org/wiki/Khotyn>, Chernivtsi Oblast <https://en.wikipedia.org/wiki/Chernivtsi_Oblast> (province <https://en.wikipedia.org/wiki/Oblast>) of western Ukraine <https://en.wikipedia.org/wiki/Ukraine>... Construction on the current Khotyn fortress was started in 1325, while major improvements were made in the 1380s and in the 1460s.” Off wiki Related to Wikimania 2019’s focus on the Sustainable Development Goals <https://en.wikipedia.org/wiki/Sustainable_Development_Goals>, I sometimes think about what happens to recycled materials. This article from The New York Times Magazine <https://www.nytimes.com/2019/08/21/magazine/the-big-business-of-scavenging-in-postindustrial-america.html> reports that “The recycling of scrap metal is a $32 billion business in the United States, according to IBISWorld.” The article discusses the business of scavenging for metals and recycling them.
