Page and Brin originally nicknamed the new search engine "BackRub", because the system checked backlinks to estimate the importance of a site. Hassan as well as Alan Steremberg were cited by Page and Brin as being critical to the development of Google. Rajeev Motwani and Terry Winograd later co-authored with Page and Brin the first paper about the project, describing PageRank and the initial prototype of the Google search engine, published in 1998. Héctor García-Molina and Jeff Ullman were also cited as contributors to the project. PageRank was influenced by a similar page-ranking and site-scoring algorithm earlier used for RankDex, developed by Robin Li in 1996, with Larry Page's PageRank patent including a citation to Li's earlier RankDex patent; Li later went on to create the Chinese search engine Baidu.
From August 26 to 29, Dorian produced damaging winds and heavy rain across the eastern Caribbean. In Barbados, winds reached 55 mph (89 km/h), downing trees and power lines. Isolated interruptions to power occurred on St. Lucia; no damage occurred otherwise in the nation. In Martinique, heavy rains—peaking at 102 mm (4.0 in) in Rivière-Pilote—and winds up to 61 mph (98 km/h) caused some damage, though overall damage was negligible. Heavy showers in Dominica left multiple communities without power and water. Rainfall extended north to Guadeloupe were accumulations reached 121 mm (4.8 in) in Matouba. Striking the Virgin Islands as an intensifying hurricane, Dorian brought strong winds and heavy rains to the region. Buck Island, just south of Saint Thomas, experienced sustained winds of 82 mph (132 km/h) and a peak gust of 111 mph (179 km/h). Wind gusts on Saint Thomas reached 75 mph (121 km/h). Island-wide blackouts occurred on Saint Thomas and Saint John, while 25,000 customers lost power on Saint Croix. The high winds downed trees across the islands. Along the coast, multiple boats broke from their moorings and washed ashore. Some flooding occurred on Tortola in the British Virgin Islands. Downed trees knocked out power to some residences on Virgin Gorda. Because the hurricane moved farther northeast than initially anticipated, its effects in Puerto Rico were relatively limited. A man in Bayamón died when he fell off his roof trying to clean drains in advance of the storm.
More InfoAt 16:40 UTC on September 1, Dorian made landfall on Great Abaco Island in the Bahamas, with one-minute sustained winds of 185 mph (298 km/h), wind gusts over 220 mph (355 km/h), and a central barometric pressure of 910 millibars (27 inHg), as Dorian reached its peak intensity during landfall. Storm chaser Josh Morgerman observed a pressure of 913.4 mbar (26.97 inHg) in Marsh Harbour. Dorian's forward speed decreased around this time, slowing to a westward crawl of 5 mph (8.0 km/h). At 02:00 UTC on September 2, Dorian made landfall on Grand Bahama near the same intensity, with the same sustained wind speed. Afterward, Dorian's forward speed slowed to just 1 knot (1.2 mph; 1.9 km/h), as the Bermuda High that was steering the storm westward weakened. Later that day, the storm began to undergo an eyewall replacement cycle to the north of Grand Bahama; the Bermuda High to the northeast of Dorian also collapsed, causing Dorian to stall just north of Grand Bahama. Around the same time, the combination of the eyewall replacement cycle and upwelling of cold water caused Dorian to begin weakening, with Dorian dropping to Category 4 status at 15:00 UTC. Due to the absence of steering currents, Dorian stalled north of Grand Bahama for about a day. Dorian subsequently weakened to a Category 2 storm on September 3, before beginning to move northwestward at 15:00 UTC, parallel to the east coast of Florida, with Dorian's wind field expanding during this time.
More InfoPrior to Dorian's arrival in the Lesser Antilles, local governments issued various tropical cyclone warnings and watches across the islands. LIAT cancelled multiple flights across the Lesser Antilles due to the storm and airports across the Virgin Islands temporarily suspended operations. Many of the threatened islands suffered devastating impacts in 2017 from Hurricanes Irma and Maria, lending to greater vigilance. In Barbados, thirty-eight shelters opened island-wide, with 103 residents seeking refuge in them. All public services were suspended for the duration of the storm. Homeless persons were transported to shelter by emergency personnel. On August 26, St. Lucia prime minister Allen Chastanet announced that the nation would "shut down" for the duration of Dorian. In Dominica, Prime Minister Roosevelt Skerrit ordered all public sector workers to remain home and prepare for the storm. The Ministry of Public Works mobilized heavy machinery and the police were placed on high alert.
More InfoDavid Sutton was director of AAT Corporation and EHG Corporation when they held mineral licenses in North Korea and did business with Korean Natural Resources Development and Investment Corporation, which is under United Nations sanctions, and North Korea's "primary arms dealer and main exporter of goods and equipment related to ballistic missiles and conventional weapons, responsible for approximately half of the arms exported by North Korea." The geologist, Louis Schurmann, said British billionaire Kevin Leech was key to putting the deal together. Leaked documents also reveal the involvement of another Briton, Gibraltar-based John Lister. According to ABC, the Department of Foreign Affairs and Trade was aware of these mining deals, which had also been brought up in the Australian Senate, but nobody ever referred the matter to the Australian Federal Police.
More InfoDorian developed from a tropical wave on August 24 over the Central Atlantic. The storm moved through the Lesser Antilles and became a hurricane north of the Greater Antilles on August 28. Dorian proceeded to undergo rapid intensification over the following days to reach its peak as a Category 5 hurricane with one-minute sustained winds of 185 mph (295 km/h) and a minimum central pressure of 910 millibars (26.87 inHg) by September 1. It made landfall in the Bahamas in Elbow Cay, just east of Abaco Island, and again on Grand Bahama several hours later, where it remained nearly stationary for the next day or so. After weakening considerably, Dorian began moving northwestward on September 3, parallel to the east coast of Florida. Dwindling in strength, the hurricane turned to the northeast the next day and made landfall on Cape Hatteras at Category 2 intensity on September 6. It transitioned into an extratropical cyclone before striking first Nova Scotia and then Newfoundland with hurricane-force winds on September 8. It finally dissipated near Greenland on September 10.
