The serpent is an ancient, low-sounding wind instrument in an 'S' shape. It looks a bit like a snake or serpent. It is made of wood, but had a mouthpiece similar to a trumpet and is classified as a brass instrument. The serpent has a range from C below the bass clef to around F above middle C. It was perhaps invented by Frenchman, Edme Guillaume, in the late 1500s. It made a comeback in the late 1800s and can be heard in Berlioz' "Symphonie Fantastique".
The nearest musical instrument to the serpent is the ophicleide, which replaced it in the 19th century. Its place was taken later on by valved bass brass instruments such as the euphonium and tuba.
Xbox
Xbox is a video game console system made by Microsoft. It began in 1998 when four employees decided to try to make a system to compete with Sony's PlayStation 2. The employees took apart four Dell computers and built the console from the parts. The employees named the console DirectX Box because it used Microsoft's DirectX graphics program. They showed the console to Ed Fries, who was the leader of Microsoft's game publishing business, and he liked the idea. During work on the project, the name was changed to Xbox.
There are three generations of the Xbox.

Arrow's impossibility theorem
Arrow's impossibility theorem, Arrow's theorem, or Arrow's paradox is a statement from social choice theory, named after economist Kenneth Arrow, who first described it in 1950: Suppose there is a vote, and voters have at least three different options to choose from. Each voter will then rank the options according to his or her preference. Arrow said, that in such a case, there is no way to convert these rankings into a community-wide complete and transitive ranking while also meeting certain criteria.
Arrow demonstrated the theorem in his doctoral thesis. He popularized it in his 1951 book "Social Choice and Individual Values". The original paper was titled "A Difficulty in the Concept of Social Welfare".
In short, the theorem states that no rank-order electoral system can be designed that always satisfies these three "fairness" criteria:
2018 Liège attack
On 29 May 2018, a man on temporary leave from prison "hunted down" and stabbed two female police officers, then took their guns and used them to shoot and kill the two officers and a pedestrian in Liège, Belgium.

Stranger than Fiction (2006 movie)
Stranger than Fiction is a 2006 American fantasy comedy-drama movie directed by Marc Forster, produced by Lindsay Doran, and written by Zach Helm. The movie stars Will Ferrell, Maggie Gyllenhaal, Dustin Hoffman, Queen Latifah, Kristin Chenoweth with Emma Thompson and Linda Hunt.
The main plot follows Harold Crick (portrayed by Ferrell), an IRS worker who begins hearing a disembodied voice narrating his life as it happens – seemingly the text of a novel in which it is stated that he will soon die – and he frantically seeks to somehow prevent that ending.
The movie was shot on location in Chicago. It was released by Columbia Pictures on November 10, 2006 and made $53.7 million at the box office. Roger Ebert gave it 3.5 out of 4 stars and praised Ferrell's performance.
