Athabasca named Athabasca Landing, is a town in northern Alberta, Canada. It is located 145 km north of Edmonton at the intersection of Highway 2 and Highway 55, on the banks of the Athabasca River, it is the centre of Athabasca County. It was known as Athabasca Landing prior to August 4, 1913. Unlike many other towns in Alberta, Athabasca predates the railway, it was the terminus of the Edmonton to Athabasca Landing trail. Athabasca lies on a southern protrusion of the Athabasca River. During the fur trade era, when rivers were the principal means of transportation, the Athabasca–Edmonton trail connected two different drainage basins; the Athabasca River flows north and is part of the Mackenzie River watershed, which leads to the Arctic Ocean. Edmonton lies across a height-of-land on the North Saskatchewan River in the Nelson River drainage basin, which empties into Hudson Bay. Edmonton was in Rupert's Land but not Athabasca; the trail allowed goods to be portaged forth between river systems. Once agricultural settlement occurred, the trail served a similar purpose.

Road and rail links would trace the same path. A massive forest fire in August 1913 destroyed a good portion of the town, including 30 businesses. There was no loss of life. Rebuilding of the town began immediately; the Athabasca Heritage Society put up signs through the downtown as well as along the riverfront that explain and depict the history. It has published a historical walking tour, available from the town office and visitor information centre.

The Dent d'Oche is a mountain in the Haute-Savoie region of France, in the Chablais massif, near the Swiss-French border, that rises to 2,221 m in altitude. It towers above Évian and Lake Geneva, it offers a view of the Swiss Alps and the Swiss prealps. It is the northernmost summit above 2,000 m in France. About 100 m below the summit is a refuge of the refuge de la Dent d'Oche. In summer, the refuge and the summit can be reached by a hike, doable without special equipment, but more difficult than the usual routes to nearby peaks such as Cornettes de Bise and Le Grammont. Reaching the refuge involves some short climbing sections for which chains are provided; the hike from the refuge up to the summit involves some unsecured sections along a cliff, where a misstep would be fatal. There is an alternative hiking route to the summit, from the east, more delicate; the north face route, with a rise of 350 m, is one of the most difficult climbs of the Chablais Alps. Certain sections require extensive technical skill.

The first ascent of the north face was achieved by Joseph Ravanel, his siblings Arthur and Camille and François Jacquier on 6 June 1925. Dent d'Oche on Summitpost

Stephen Wiltshire is a British architectural artist and autistic savant. He is known for his ability to draw a landscape from memory after seeing it just once, his work has gained worldwide popularity. In 2006, Wiltshire was made a Member of the Order of the British Empire for services to art. In the same year, he opened a permanent gallery on the Royal Opera Arcade in London. Stephen Wiltshire was born in England, in 1974 to Caribbean parents, he grew up in Maida Vale, London. Wiltshire was mute. At the age of three, he was diagnosed with autism; the same year, his father died in a motorbike accident. At the age of five, Wiltshire was sent to Queensmill School in London where he expressed interest in drawing, his early illustrations depicted cars. When he was about seven, Wiltshire became fascinated with sketching landmark London buildings. After being shown a book of photos depicting the devastation wrought by earthquakes, he began to create detailed architectural drawings of imaginary cityscapes.

He began to communicate through his art. The instructors at Queensmill School would deal with his lack of verbal communication skills by temporarily taking away his art supplies so that he would be forced to learn to ask for them. Stephen responded by making sounds and uttered his first word—"paper", his teachers encouraged his drawing, with their aid Wiltshire learned to speak at the age of nine. In June 2015, the BBC's Lucy Ash reported: "Soon people outside the school started noticing Stephen's gift and aged eight he landed his first commission—a sketch of Salisbury Cathedral for the former Prime Minister Edward Heath"; when he was ten, Wiltshire drew a sequence of drawings of London landmarks, one for each letter, that he called a "London Alphabet". In 1987, Wiltshire was part of the BBC programme The Foolish Wise Ones. Drawings, a collection of his works, was published that same year. Between 1995 and his graduation in 1998, Wiltshire attended the City and Guilds of London Art School in Kennington, South London.

Wiltshire can look at a subject once and draw an accurate and detailed picture of it. He draws entire cities from memory, based on single, brief helicopter rides. For example, he produced a detailed drawing of four square miles of London after a single helicopter ride above that city, his nineteen-foot-long drawing of 305 square miles of New York City is based on a single twenty-minute helicopter ride. He draws fictional scenes, for example, St. Paul's Cathedral surrounded by flames. Wiltshire's early books include Drawings, Floating Cities, Stephen Wiltshire's American Dream. Floating Cities was number one on the Sunday Times best-seller list. In 2003, a retrospective of his work,'Not a Camera: the Unique Vision of Stephen Wiltshire', was held in the Orleans House gallery in Twickenham, London. In May 2005 Wiltshire produced his longest panoramic memory drawing of Tokyo on a 32.8-foot-long canvas within seven days following a helicopter ride over the city. Since he has drawn Rome, Hong Kong, Madrid, Dubai and London on giant canvasses.

When Wiltshire took the helicopter ride over Rome, he drew it in such great detail that he drew the exact number of columns in the Pantheon. In October 2009 Wiltshire completed the last work in the series of panoramas, an 18-foot memory drawing of his "spiritual home", New York City. Following a 20-minute helicopter ride over the city he sketched the view of Manhattan, the Hudson shoreline of New Jersey, the Financial District, Ellis Island, the Statue of Liberty, Brooklyn over five days at the Pratt Institute, a college of art and design in New York City. In 2010, he made a panorama of Sydney to raise awareness of Autism Spectrum Australia, he visited Bermuda National Gallery where the sale of his donated drawing of Hamilton raised over $22,000. In June 2010, Christie's auctioned off an oil painting of his "Times Square at Night". Wiltshire started a tour of China with a first project taking him to Shanghai. A 2011 project in New York City involved Wiltshire's creation of a 250-foot long panoramic memory drawing of New York, now displayed on a giant billboard at John F. Kennedy International Airport.

It is a part of a global advertising campaign for the Swiss bank UBS that carries the theme "We will not rest", The New York Times reported. In July 2014, Wiltshire drew an aerial panorama of the Singapore skyline from memory after a brief helicopter ride, taking five days to complete the 1 x 4m artwork; the artwork was presented to President Tony Tan as the Singapore Press Holding's gift to the nation in celebration of Singapore's 50th birthday in 2015, will be displayed at Singapore City Gallery, visitor centre of the country's urban planning authority, Urban Redevelopment Authority. Wiltshire's work has been the subject of many TV documentaries. Renowned neurologist Oliver Sacks wrote about him in a chapter on prodigies in his book An Anthropologist on Mars. In 1989, Wiltshire appeared on the cover of You magazine with actor Dustin Hoffman, who had portrayed autistic savant Raymond Babbitt in the 1988 Oscar-winning film, Rain Man, which Wiltshire considers to be one of his favourite movies.

In 2006, Wiltshire was appointed a Member of the Order of the British Empire for services to art. In September 2006 Wiltshire opened his permanent gallery in the Royal Opera Arcade, Pall Mall, London. On 15 February 2008, ABC News named him Person of the Week. In July 2009 he acted as amb

The Glicko rating system and Glicko-2 rating system are methods for assessing a player's strength in games of skill, such as chess and Go. It was invented by Mark Glickman as an improvement of the Elo rating system, intended for the primary use as a chess rating system. Glickman's principal contribution to measurement is "ratings reliability", called RD, for ratings deviation. Both Glicko and Glicko-2 rating systems are under public domain and found implemented on game servers online, competitive programming competitions; the formulas used. The RD measures the accuracy of a player's rating, with one RD being equal to one standard deviation. For example, a player with a rating of 1500 and an RD of 50 has a real strength between 1400 and 1600 with 95% confidence. Twice the RD is subtracted from their rating to calculate this range. After a game, the amount the rating changes depends on the RD: the change is smaller when the player's RD is low, when their opponent's RD is high; the RD itself decreases after playing a game, but it will increase over time of inactivity.

The Glicko-2 rating system improves upon the Glicko rating system and further introduces the rating volatility σ. A slightly modified version of the Glicko-2 rating system is implemented by the Australian Chess Federation; these steps only apply to the original Glicko system, not its successor, Glicko-2. If the player is unrated, the rating is set to 1500 and the RD to 350; the new Ratings Deviation is found using the old Ratings Deviation: R D = min where t is the amount of time since the last competition and'350' is assumed to be the RD of an unrated player. If several games have occurred within one rating period, the method treats them as having happened simultaneously; the rating period may be as long as several months or as short as a few minutes, according to how games are arranged. The constant c is based on the uncertainty of a player's skill over a certain amount of time, it can be derived from a thorough data analysis, or estimated by considering the length of time that would have to pass before a player's rating deviation would grow to that of an unrated player.

If it assumed that it would take 100 rating periods for a player's rating deviation to return to an initial uncertainty of 350, a typical player has a rating deviation of 50 the constant can be found by solving 350 = 50 2 + 100 c 2 for c. Or c = / 100 ≈ 34.6 The new ratings, after a series of m games, are determined by the following equation: r = r 0 + q 1 R D 2 + 1 d 2 ∑ i = 1 m g where: g = 1 1 + 3 q 2 π 2 E = 1 1 + 10 {\displaystyle
