Roof And Tunnel Hacking
Roof and tunnel hacking is the unauthorized exploration of roof and utility tunnel spaces. The term carries a strong collegiate connotation, stemming from its use at MIT and at the U.S. Naval Academy, where the practice has a long history. It is a form of urban exploration. Some participants use it as a means of carrying out collegiate pranks, by hanging banners from high places or, in one notable example from MIT, placing a life-size model police car on top of a university building. Others are interested in exploring inaccessible and seldom-seen places; that such exploration is unauthorized is often part of the thrill. Roofers, in particular, may be interested in the skyline views from the highest points on a campus. On August 1, 2016, Red Bull TV launched the documentary series '' URBEX – Enter At Your Own Risk'', which also chronicles roof and tunnel hacking. Vadding Vadding is a verb which has become synonymous with urban exploration. The word comes from MI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio Broadcast
Radio broadcasting is the broadcasting of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in ''satellite radio'' the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network that provides content in a common radio format, either in broadcast syndication or simulcast, or both. The encoding of a radio broadcast depends on whether it uses an analog or digital signal. Analog radio broadcasts use one of two types of radio wave modulation: amplitude modulation for AM radio, or frequency modulation for FM radio. Newer, digital radio stations transmit in several different digital audio standards, such as DAB (Digital Audio Broadcasting), HD radio, or DRM ( Digital Radio Mondia ...

Burglarious Instruments
Lock picking is the practice of unlocking a Lock (security device), lock by manipulating the components of the lock device without the original key. Although lock-picking can be associated with Intention (criminal law), criminal intent, it is an essential skill for the legitimate profession of locksmithing, and is also pursued by law-abiding citizens as a useful skill to learn, or simply as a hobby (locksport). In some countries, such as Japan, lock-picking tools are illegal for most people to possess, but in many others, they are available and legal to own as long as there is no intent to use them for criminal purposes. History Lock (security device), Locks by definition secure or fasten something with the intention that access is possible only with the matching key. Despite this, criminal lock picking likely started with the first locks. Famed locksmith Alfred Charles Hobbs said in the mid-1800s: Professional and recreational lock picking also has a long history. Ki ...

Burglary
Burglary, also called breaking and entering (B&E) or housebreaking, is a property crime involving the illegal entry into a building or other area without permission, typically with the intention of committing a further criminal offence. Usually that offence is theft, larceny, robbery, or murder, but most jurisdictions include others within the ambit of burglary. To commit burglary is to ''burgle'', a term back-formed from the word ''burglar'', or to ''burglarize''. Etymology Sir Edward Coke (1552–1634) explains at the start of Chapter 14 in the third part of '' Institutes of the Lawes of England'' (pub. 1644), that the word ''Burglar'' ("or the person that committeth burglary"), is derived from the words ''burgh'' and ''laron'', meaning ''house-thieves''. A note indicates he relies on the ''Brooke's case'' for this definition. According to one textbook, the etymology originates from Anglo-Saxon or Old English, one of the Germanic languages. (Perhaps paraphrasing Sir Edward ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trespassing
Trespass to land, also called trespass to realty or trespass to real property, or sometimes simply trespass, is a common law tort or a crime that is committed when an individual or the object of an individual intentionally (or, in Australia, negligently) enters the land of another without a lawful excuse. Trespass to land is ''actionable per se''. Thus, the party whose land is entered upon may sue even if no actual harm is done. In some jurisdictions, this rule may also apply to entry upon public land having restricted access. A court may order payment of damages or an injunction to remedy the tort. By law, trespass for mesne profits is a suit against someone who has been ejected from property that did not belong to them. The suit is for recovery of damages the trespasser caused to the property and for any profits he or she may have made while in possession of that property. For a trespass to be actionable, the tortfeasor must voluntarily go to a specific location but need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A History Of Hacks And Pranks At MIT
A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is '' a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, '' a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest known ancestor of A is ''aleph''—the first letter of the Phoenician ...

Single Rope Technique
The single-rope techniques (SRT) are a set of methods used to descend and ascend on the same single rope. Single-rope techniques are used in caving, potholing, rock climbing, canyoning, roped access for building maintenance, and by arborists for tree climbing, although to avoid confusion in the tree climbing community, many have taken to calling them "stationary" rope techniques. Single-rope techniques are used in contrast to Tree climbing#Doubled-rope technique, double-rope techniques (DRT), also known as the moving-rope techniques. Historical developments In the 1930s, as caving became increasingly popular in France, several clubs in the Alps made vertical cave exploration an outdoor sport. During World War II, a team composed of Pierre Chevalier (caver), Pierre Chevalier, Fernand Petzl, Charles Petit-Didier, and others explored the Dent de Crolles cave system near Grenoble, France, which became the deepest explored cave in the world (–658m) at that time.

Elevator Surfing
Elevator surfing, also known as lift surfing, is the usually clandestine activity of riding on top of elevators, rather than inside them. More experienced surfers may attempt riskier maneuvers such as jumping between moving elevators, or riding the elevator's counterweight. Elevator surfing is typically considered a form of urban exploration, aligned more with investigative experiences like rooftopping and tunnel hacking than with adventurous urban sports like train surfing. While elevator surfing was most prominent as a subculture in the United States and United Kingdom in the 1990s, it made a comeback in the late 2010s, with partakers often posting footage of their adventures on YouTube and similar platforms. Access into the elevator shaft (Hoistway) is often achieved using an elevator key—like those carried by first responders and building maintenance staff—to open the outer doors. Alternatively, participants may utilize lock picking techniques or use tools like coat hange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elevator Shaft
An elevator (American English) or lift (Commonwealth English) is a machine that vertically transports people or freight between levels. They are typically powered by electric motors that drive traction cables and counterweight systems such as a hoist, although some pump hydraulic fluid to raise a cylindrical piston like a jack. Elevators are used in agriculture and manufacturing to lift materials. There are various types, like chain and bucket elevators, grain augers, and hay elevators. Modern buildings often have elevators to ensure accessibility, especially where ramps aren't feasible. High-speed elevators are common in skyscrapers. Some elevators can even move horizontally. History Pre-industrial era The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes ( – ) built his first elevator probably in 236 BC. Sources from later periods mention elevators as cabs on a hemp rope, powered by people or a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duct Tape
Duct tape or duck tape is cloth- or scrim-backed pressure-sensitive tape, often coated with polyethylene. A variety of constructions exist using different backings and adhesives, and the term "duct tape" has been genericized to refer to all of them. A variation is heat-resistant foil tape useful for sealing heating and cooling ducts, produced because standard duct tape fails when used on heating ducts. Duct tape is generally silvery gray in color, but also available in other colors and printed designs, from whimsical yellow ducks to practical camouflage patterns. It is often confused with gaffer tape which is designed to be non-reflective and cleanly removed, unlike duct tape. During World War II, Revolite (then a division of Johnson & Johnson) developed an adhesive tape made from a rubber-based adhesive applied to a durable duck cloth backing. This tape resisted water and was used to seal some ammunition cases during that period. "Duck tape" is recorded in the ''Oxford ...

Buildering
Buildering (also known as edificeering, urban climbing, structuring, skywalking, boulding, or stegophily) describes the act of climbing on the outside of buildings and other artificial structures. If done without ropes or protection far off the ground, buildering is extremely dangerous. It is often practiced outside legal bounds, and is thus practiced mostly at night. Night climbing is a particular branch of buildering which has been practiced for many years in a variety of locations, especially at the Universities of Oxford and Cambridge, England. Night climbing, as distinct from buildering, is performed mainly by undergraduates under cover of darkness. The term "night climbing" has replaced the older term "roof climbing". The philosophy behind night climbing has undergone great change during the 21st century, with urban disciplines such as parkour having a heavy influence on the evolution of night climbing techniques and movements. Adepts of buildering who are seen climbing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
