Many modern computers have operating systems that permit several applications or programs to run at the same time. Each running program uses one or more so-called "processes", that's why this situation is generally known as multiprocessing. At times it can happen, that a process stops responding to user input; the user sees when the computer stops responding to inputs, or it becomes very slow. Different causes can cause this scenario: The most frequent are deadlock, race conditions or the system simply having too much to do. In many cases, the only solution is to terminate the processes, which cause so much load. Many GUI-based operating systems have programs that allow the user to tell the operating system to terminate a process. There may also be command-line programs that do this. When the operating system terminates a process, all unsaved data of the process will be lost.
In the case where the operating system detects such a situation, it may show a BSoD.
8 track tape
The 8-track is a music format which first appeared in the 1960s. It is a tape format which was created so people could play music in their cars. Unlike cassettes, 8 tracks are a continuous loop of tape. They did not need to be turned over to keep playing. There were four programs of music on each tape with two tracks on each program to create stereo sound. When the track was over, a very thin piece of metal in the tape would be sensed. This would cause the part of the player that read the tape (the "head") to start reading the next track. 8 tracks became very popular in the early 1970s. They were used both in the home and car.
In the 1970s, the cassette tape was improved. It eventually had better quality than 8-tracks. By the late 1970s, cassettes became more popular than 8-tracks. In 1980, 8-tracks were rarely being made. They could still be bought through mail order record clubs until 1987. Today there are still a small number of people who collect 8 tracks.
The 8-track had many problems. Unlike cassettes, the rubber roller was in the cartridge. It would often wear out. This could cause a gooey substance in the tapes. This also caused the tapes to wear out quickly. The spacing between the tracks were very narrow. Music from tracks other than the one being played could often be heard. The sensing foil in the tape would sometimes break off. This would stop the tape from changing tracks.
Le Plateau-Mont-Royal
Le Plateau-Mont-Royal is a neighborhood in Montreal. It is northeast of downtown. It was a middle class neighborhood where many Québécois, Portuguese, and Jewish people lived. In the 1980s, many artists moved into the neighborhood. They liked the low rent and the beautiful architecture. Today, Le Plateau is a very expensive area to live. There are many popular shops and restaurants.
Côte-des-Neiges
Côte-des-Neiges is a working class neighborhood in Montreal, Canada. It is north of downtown on the other side of Mount Royal. The west side of the neighborhood is very ethnic with many shops that cater to this population. Most of the people here live in apartment buildings built after 1945. The eastern part of Côte-des-Neiges is more Québécois and more of an upperclass neighborhood. North America's largest church, St. Joseph's oratory, is here, as well as the University of Montreal.

Sinornithosaurus
Sinornithosaurus (derived from Latin and Greek, meaning 'Chinese bird-lizard') was a feathered dinosaur from the Lower Cretaceous, a dromaeosaur. It was found in the Yixian Formation in what is now China.
This new fossil supports the idea that these dinosaurs did not have scaly, reptile-like skin, but had a softer, downy coat. No fossil skin impressions of these dinosaurs had been found previously.
Sinosauropteryx
Sinosauropteryx
is a genus of non-avialan dinosaur ("not" a bird).
It is the first one found with the fossilized impressions of furry down or filamentous feathers. Overall, the filaments resemble the down-like feathers of some modern flightless birds.
"Sinosauropteryx" lived in China during the early Cretaceous period and was a close relative of "Compsognathus". It has been dated to 124.6–122 million years ago.
The fossils were from the famous Jehol biota of Sihetun, Liaoning Province, China, and represent an ancient lake bed.
Most paleontologists do not consider "Sinosauropteryx" to be a bird, because phylogenetically, it lies far from the "clade" Aves, usually defined as "Archaeopteryx" plus modern birds.
"Sinosauropteryx prima" is among the smallest known non-avian theropods, with the type specimen (a nearly mature individual) measuring only in length, including a very long tail.
Paleontologist Nick Longrich suggested that these specimens preserve remnants of the original colour pattern the animal would have had in life. He argued that the dark, banded stains on the tail were too evenly spaced to have been caused by random separation of the fossil slabs, and that they represent fossilized pigments present in the feathers.
The presence of dark feathers along only the top of the body may also reflect the colour pattern in life, indicating that "Sinosauropteryx prima" was countershaded with dark colour on its back and lighter colour on its underside, with bands or stripes on the tail for camouflage. The main colour turned out later to be ginger.
Unenlagia
Unenlagia was a theropod from the mid-Cretaceous, living about 90 million years ago. The first birds appeared 150 million years ago, evolving from dinosaurs long before "Unenlagia" lived. Therefore, it is not an ancestor of modern-day birds, but was an evolutionary dead-end. The most bird-like dinosaur ever discovered is the 90-million-year-old "Unenlagia comahuensis", a flightless, 4-foot tall, 7.5-foot-long carnivore.
Subversion
Subversion is a systematic attempt to overthrow or undermine a government or political system by persons working from within. Subversion works against structures of power, authority, exploitation, servitude, and hierarchy. A subversive is something or someone that works against an organization or system.
Subversive activity is the lending of aid, comfort, and support to individuals, groups, or organizations that work for the "overthrow of governments by force and violence". Actions against the best interests of the government, and which are not treason, sedition, sabotage, or espionage are put in the category of subversive activity.
Subversion is a crime in China. The government of the People's Republic of China prosecutes subversives under Articles 102 through 112 of the state criminal law. These laws describe behavior that can be a threat to national security. China has prosecuted many dissidents using these laws. Articles 105 and 111 are used the most often to silence political dissent. Article 105 makes it a crime to organize, make a secret plan, work against the national order, or tell rumors to make people fight the national order or overthrow the socialist system. Article 111 prohibits stealing, secretly collecting, purchasing, or illegally providing state secrets or intelligence to an organization, institution, or personnel outside the country.
There is no crime defined as "subversion" in British Constitutional law. There is a crime of treason. Legal experts have tried define subversion, but political and legal thinkers could not reach a general agreement.
Michio Kaku
Dr. Michio Kaku (born 24 January 1947) is a Japanese-American theoretical physicist and a performer on the Science Channel, particularly for Sci-Fi Science. He is known as a "sci-fi fan" on the SC.
Kaku was born on January 24, 1947 in San Jose, California to Japanese parents. As a child, he took judo lessons. When he grew older, he graduated from college with a summa cum laude degree.
