ReCAPTCHA V1
reCAPTCHA Inc. is a CAPTCHA system owned by Google. It enables web hosts to distinguish between human and automated access to websites. The original version asked users to decipher hard-to-read text or match images. Version 2 also asked users to decipher text or match images if the analysis of cookies and canvas rendering suggested the page was being downloaded automatically. Since version 3, reCAPTCHA will never interrupt users and is intended to run automatically when users load pages or click buttons. The original iteration of the service was a mass collaboration platform designed for the digitization of books, particularly those that were too illegible to be Optical character recognition, scanned by computers. The verification prompts utilized pairs of words from scanned pages, with one known word used as a control for verification, and the second used to crowdsourcing, crowdsource the reading of an uncertain word. reCAPTCHA was originally developed by Luis von Ahn, David A ...

CECB
A coupon-eligible converter box (CECB) was a digital television adapter that met eligibility specifications for subsidy "coupons" from the United States government. The subsidy program was enacted to provide terrestrial television viewers with an affordable way to continue receiving free digital terrestrial television services after the nation's television service transitioned to digital transmission and analog transmissions ceased. The specification was developed by the National Telecommunications and Information Administration (NTIA), with input from the broadcast and consumer electronics industries as well as public interest groups. History Early proposals In March 2005, United States House Commerce Committee chairman Joe Barton of Texas said he would introduce a bill requiring the transition to digital television "sometime in the spring", saying he wanted analog broadcasting to end on December 31, 2006. Included in his plan was a $400–$500 million subsidy for conve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waymo

Google Street View
Google Street View is a technology featured in Google Maps and Google Earth that provides interactive panoramas from positions along many streets in the world. It was launched in 2007 in several cities in the United States, and has since expanded to include all of the country's major and minor cities, as well as the cities and rural areas of many other countries worldwide. Streets with Street View imagery available are shown as clickable blue lines on Google Maps. Google Street View displays interactive panoramas of stitched VR photographs. Most photography is done by car, but some is done by tricycle, camel, boat, snowmobile, underwater apparatus, and on foot. History Street View had its inception in 2001 with the Stanford CityBlock Project, a Google-sponsored Stanford University research project. The project ended in June 2006, and its technology was folded into Street View. The technology was launched on May 25, 2007, in the United States. In May 2008, Google announc ...

Fife (instrument)
A fife ( ) is a small, high-pitched, transverse aerophone, that is similar to the piccolo. The fife originated in medieval Europe and is often used in fife and drum corps, Military band, military units, and marching bands. Someone who plays the fife is called a fifer. The word ''fife'' comes from the German language, German , meaning pipe, which comes from the Latin word . The fife is a diatonically tuned instrument commonly consisting of a tube with six finger holes and an embouchure hole that produces sound when blown across. Modern versions of the fife are Total chromatic, chromatic, having 10 or 11 finger holes that allow any note to be played. On a 10-hole fife, the index, middle and ring fingers of both hands remain in the same positions as on the six-hole fife, while both thumbs and both pinkies are used to play accidentals. An 11-hole fife has holes positioned similarly but adds a second hole under the right middle finger. Fifes are made primarily of wood, such as Dalber ...

File (tool)
A file is a tool used to remove fine amounts of material from a workpiece. It is common in woodworking, metalworking, and other similar trade and hobby tasks. Most are hand tools, made of a case hardened steel bar of rectangular, square, triangular, or round cross-section, with one or more surfaces cut with sharp, generally parallel Tine (structural), teeth. A narrow, pointed Tang (tools), tang is common at one end, to which a handle may be fitted.. A rasp is a form of file with distinct, individually cut teeth used for coarsely removing large amounts of material. Files have also been developed with abrasive surfaces, such as natural or synthetic diamond tool, diamond grains or silicon carbide, allowing removal of material that would dull or resist steel files, such as ceramic. History Early filing or rasping has prehistoric roots and grew naturally out of the blending of the twin inspirations of cutting with stone cutting tools (such as hand axes) and abrasive, abrading u ...

Images Recaptcha
An image or picture is a visual representation. An image can be two-dimensional, such as a drawing, painting, or photograph, or three-dimensional, such as a carving or sculpture. Images may be displayed through other media, including a projection on a surface, activation of electronic signals, or digital displays; they can also be reproduced through mechanical means, such as photography, printmaking, or photocopying. Images can also be animated through digital or physical processes. In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term ''image'' (or ''optical image'') refers specifically to the reproduction of an object formed by light waves coming from the object. A ''volatile image'' exists or is perceived only for a short period. This may be a reflection of an object by a mirror, a projection of a camera obscura, or a scene displayed on a cathode-ray tube. A ''fixed image'', also called a hard copy, is one that has been r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MacArthur Fellowship
The MacArthur Fellows Program, also known as the MacArthur Fellowship and colloquially called the "Genius Grant", is a prize awarded annually by the MacArthur Foundation, John D. and Catherine T. MacArthur Foundation to typically between 20 and 30 individuals working in any field who have shown "extraordinary originality and dedication in their creative pursuits and a marked capacity for self-direction" and are citizens or residents of the United States. According to the foundation's website, "the fellowship is not a reward for past accomplishments but rather an investment in a person's originality, insight, and potential", but it also says such potential is "based on a track record of significant accomplishments". The current prize is $800,000 paid over five years in quarterly installments. Previously, it was $625,000. This figure was increased from $500,000 in 2013 with the release of a review of the MacArthur Fellows Program. The award has been called "one of the most signifi ...
