A derecho [deh-rey-cho] is a widespread and damaging group of severe thunderstorms which often represent with rapid forward speeds. They have a distinct appearance on radars, known as bow echos (after an archer’s bow). The common definition of the word is: a thunderstorm complex that produces a damaging wind swath of at least 240 miles, featuring a concentrated area of convectively induced wind gusts exceeding 58 mph. Some studies add further criteria, such as a requirement that no more than two or three hours separate any two successive wind reports.
Unlike other thunderstorms, which typically can be heard in the distance when approaching, a derecho seems to strike suddenly. Within minutes, extremely high winds can arise, strong enough to knock over highway signs and topple large trees. These winds are accompanied by spraying rain and frequent lightning from all directions. It is dangerous to drive under these conditions, especially at night, because of blowing debris and obstructed roadways. A derecho moves through quickly, but can do much damage in a short period of time.

He is the founder of Megaupload and its associated websites. He legally changed his surname to Dotcom in 2005. in 2012, the New Zealand Police placed him in custody in response to US charges of criminal copyright infringement in relation to his Megaupload Web site.
Dotcom has spoken out against his negative portrayal in the media, claiming to be a reformed character and a legitimate businessman who has been unfairly demonized by United States authorities and industry trade groups such as the RIAA and MPAA. He contends that the services offered by his Megaupload site were not significantly different from those of comparable services such as Rapidshare or YouTube, and he has just been used as a scapegoat because of his hacker past.

Cinespia is an organization that hosts on-site screenings of classic films in and around Los Angeles, California. Launched in 2002, Cinespia shows films from the 1930s through the 1990s mostly in open-air settings at historic locations. Its most popular series runs weekly between May and August on Saturday (and occasionally Sunday) nights at the Hollywood Forever Cemetery. In addition, it screens films, both contemporary and canonical, at other locations throughout the year.
The series was the brainchild of John Wyatt, a set designer then in his mid-twenties. A student of influential film lecturer Jim Hosney at the Crossroads School in Santa Monica, Wyatt initially formed an Italian cinema club with friend Richard Petit, which evolved into Cinespia. The name is a portmanteau of the Italian word for film, ‘cine,’ and the third person singular conjugation of the verb ‘spiare,’ meaning ‘to observe,’ or more commonly, ‘to spy.’ Conjoined, cinespia was intended to suggest a film enthusiast or ‘watcher of films,’ although the actual term for film buff in Italian is ‘cinofilo.’ Cinespia, by contrast, means literally ‘he spies in the movie theater’ or ‘cinema spy.’

Everything is Terrible! is a Chicago-based video blogging website launched in 2007 that features clips of VHS tapes from the late 20th century. The project was founded in 2000 by a group of friends while at Ohio University. They search at thrift stores, garage sales, and ‘bargain bins’ for the worst and most outrageous VHS tapes in which to share with each other. The website has also been attempting to amass the largest collection of tapes that feature the film ‘Jerry Maguire’; according to member Ghoul Skool: ‘We always have noticed since the beginning that there seems to be nothing but just ‘Jerry Maguire’ tapes filling our nation’s thrift stores. I don’t know why.’
The people behind ‘Everything is Terrible’ also perform live shows wearing cloaks and gold VHS tapes around their necks to showcase their new VHS discoveries. In 2009, the website released a video titled ‘Everything is Terrible! The Movie,’ which featured the same type of VHS clips that would be featured on their website. The ‘A.V. Club’ called the video ‘a portal into a world halfway between showbiz and real life—a look at how the people who make entertainment for a living think the rest of us saps actually live,’ adding that it’s ‘simultaneously enlightening, hilarious, and deeply sad.

Connectionism [kuh-nek-shuh-niz-uhm] is the theory that the connections (such as between brain cells) mediate thought and govern behavior. It is a set of approaches in the fields of artificial intelligence and cognitive science that model mental or behavioral phenomena as the emergent processes of interconnected networks of simple units. There are many forms of connectionism, but the most common forms use neural network models (artificial brains).
The central connectionist principle is that mental phenomena can be described by interconnected networks of simple and often uniform units. The form of the connections and the units can vary from model to model. For example, units in the network could represent neurons and the connections could represent synapses. Neural networks are able to learn by themselves, unlike normal computers, which cannot do anything for which they are not programmed.

Perceptual control theory (PCT) is a model of behavior based on the principles of negative feedback (when the output of a system acts to oppose changes to the input of a system, acting to stabilize it). It differs in a number of respects from standard engineering control theory, which deals with the behavior of dynamical systems like feedback loops. From the PCT perspective, an organism controls neither its own behavior, nor external environmental variables, but rather its own perceptions.
According to the standard catch-phrase of the field, ‘behavior is the control of perception.’ While the adoption of PCT in the scientific community has not been widespread, it has been applied to a number of areas, and has led to a method of psychotherapy called the Method of Levels.
