Gmail is email that's intuitive, efficient, and useful. 15 GB of storage, less spam, and mobile access. Television or TV is a telecommunication medium used for transmitting moving images in monochrome (black-and-white), or in color, and in two or three dimensions and sound. Foursquare’s Swarm 5.0, released yesterday on iOS and coming soon to Android, has a cleaner look and better venue categorization. Most importantly, it downplays.

Swarm's New Update Works Great Without Friends. Foursquare’s Swarm 5. OS and coming soon to Android, has a cleaner look and better venue categorization.

Most importantly, it downplays most of the social check- in app’s social elements and strengthens its solo benefits. That’s great news, because Swarm might be more useful if you use it alone. The early promise of Foursquare (and its predecessor Dodgeball) was to help people meet up with their friends by selectively sharing their location. This would give people a sort of social radar that let them meet up ad hoc. Unlike Google Maps or Apple’s Find Friends, Swarm leaves the user in control of each check- in, making it less exhibitionist but also less frictionless.

Yesterday Foursquare updated to allow your friends to check you in to places (with your. But not even Facebook could convince people to report every time they showed up at a bar or restaurant. Instagram, Twitter, and Snapchat adopted location tags too, but while this makes for excellent after- the- fact content aggregation, most people don’t use it frequently enough to enable serendipity- based drop- ins. Swarm’s social elements (like becoming “mayor” of your favorite venue or collecting points for weekly contests) aren’t that useful unless your friends are fellow diehards. As a longtime diehard (and acquaintance of Foursquare’s founders) I’ve seen fewer and fewer of the early core users check in, while newer friends have never joined. The social panel of the app has become a ghost town populated by people I knew better in 2.

But that hasn’t discouraged me from checking in (which now often takes just a swipe and a tap from your lock screen). I’m not here for the points or even the casual hangouts; I’m here to keep a journal of where I’ve been, which I end up consulting several times a week. Foursquare is fairly open about Swarm 5’s shift toward solo features.

This was the focus for Swarm 5. The company still benefits as long as you’re providing it data, which it then sells to advertisers. According to Wired, “ad- targeting and other services allow the company to make money from a relatively small user base.” As usual, the service is free because you’re the product. Or in another sense, you’re the free labor, and the database you’re building is the product. Not a bad trade- off. Swarm’s main display used to show where your friends had checked in. Now that display shares equal billing with a solo view, displaying a timeline and map of your past check- ins.

You can share this map, but more importantly, you can analyze it next time you’re trying to remember what you did Friday night, or returning to your old neighborhood and wondering what to eat. Your Swarm check- ins also help Foursquare customize your recommendations, which gives it an edge over Yelp, but you can already customize your recs by answering some questions about your tastes. Check- ins also help your friends see your recommendations, but again, that doesn’t matter if your friends aren’t on it. That record of where you’ve been is still the killer app. Whenever you’re tired and you just want to go somewhere familiar, just open Foursquare and flick on the “You’ve been” filter. Every now and then, rate your past visits on Foursquare, and you’ll have a list of places you’ve “liked.” Now it’ll be easy to pick somewhere to meet up or to recommend to a visiting friend. All this takes minimal effort, and doesn’t require carefully curating lists, writing tips, or connecting with all your friends.

And maybe you shouldn’t connect with your friends, even if you can. What will you get from their occasional check- ins, besides FOMO, meaningless likes, and annoying updates about competing for points?

Television - Wikipedia. This article is about television as a medium. For the appliance itself, see television set. The term can refer to a television set, a television program (. Television is a mass medium for entertainment, education, news, politics, gossip, and advertising.

Television became available in crude experimental forms in the late 1. After World War II, an improved form of black- and- white TV broadcasting became popular in the United States and Britain, and television sets became commonplace in homes, businesses, and institutions. During the 1. 95.

The availability of multiple types of storage media such as Betamax, VHS tape, local disks, DVDs, flash drives, high- definition Blu- ray Discs, and digital video recorders have enabled viewers to watch prerecorded material—such as movies— at home on their own time schedule. For many reasons, the storage of television and video programming now occurs on the cloud. At the end of the first decade of the 2. Another development was the move from standard- definition television (SDTV) (5. HDTV), which provides a resolution that is substantially higher. HDTV may be transmitted in various formats: 1.

Since 2. 01. 0, with the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Video, i. Player, Hulu, Roku and Chromecast. In 2. 01. 3, 7. 9% of the world's households owned a television set. Most TV sets sold in the 2. LEDs. Major manufacturers announced the discontinuation of CRT, DLP, plasma, and even fluorescent- backlit LCDs by the mid- 2. Alternatively television signals are distributed by coaxial cable or optical fiber, satellite systems and, since the 2. Internet. Until the early 2.

A standard television set is composed of multiple internal electronic circuits, including a tuner for receiving and decoding broadcast signals. A visual display device which lacks a tuner is correctly called a video monitor rather than a television.

Etymology. The word television comes from Ancient Greek. The first documented usage of the term dates back to 1.

Russian scientist Constantin Perskyi used it in a paper that he presented in French at the 1st International Congress of Electricity, which ran from 1. August 1. 90. 0 during the International World Fair in Paris. The Anglicised version of the term is first attested in 1. The use of the term to mean .

The slang term . Another slang term for the TV is . This schematic shows the circular paths traced by the holes that may also be square for greater precision. The area of the disk outlined in black shows the region scanned. Facsimile transmission systems for still photographs pioneered methods of mechanical scanning of images in the early 1. Alexander Bain introduced the facsimile machine between 1.

Frederick Bakewell demonstrated a working laboratory version in 1. As a 2. 3- year- old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1. Although he never built a working model of the system, variations of Nipkow's spinning- disk . Perskyi's paper reviewed the existing electromechanical technologies, mentioning the work of Nipkow and others. Fournier in Paris in 1. A matrix of 6. 4 selenium cells, individually wired to a mechanical commutator, served as an electronic retina.

In the receiver, a type of Kerr cell modulated the light and a series of variously angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. A separate circuit regulated synchronization. The 8x. 8 pixel resolution in this proof- of- concept demonstration was just sufficient to clearly transmit individual letters of the alphabet. An updated image was transmitted . Moving images were not possible because, in the scanner: . On 2. 5 March 1. 92. Baird gave the first public demonstration of televised silhouette images in motion, at Selfridge's Department Store in London.

By 2. 6 January 1. This is widely regarded as the first television demonstration. The subject was Baird's business partner Oliver Hutchinson. Baird's system used the Nipkow disk for both scanning the image and displaying it. A bright light shining through a spinning Nipkow disk set with lenses projected a bright spot of light which swept across the subject. A Selenium photoelectric tube detected the light reflected from the subject and converted it into a proportional electrical signal.

This was transmitted by AM radio waves to a receiver unit, where the video signal was applied to a neon light behind a second Nipkow disk rotating synchronized with the first. The brightness of the neon lamp was varied in proportion to the brightness of each spot on the image. As each hole in the disk passed by, one scan line of the image was reproduced. Baird's disk had 3. In 1. 92. 7, Baird transmitted a signal over 4. London and Glasgow. In 1. 92. 8, Baird's company (Baird Television Development Company/Cinema Television) broadcast the first transatlantic television signal, between London and New York, and the first shore- to- ship transmission.

In 1. 92. 9, he became involved in the first experimental mechanical television service in Germany. In November of the same year, Baird and Bernard Natan of Path. In 1. 93. 1, he made the first outdoor remote broadcast, of the Epsom Derby. Baird's mechanical system reached a peak of 2. BBC television broadcasts in 1. Instead a 1. 7. 5mm film was shot, rapidly developed and then scanned while the film was still wet.

An American inventor, Charles Francis Jenkins, also pioneered the television. He published an article on .

In 1. 92. 5 Jenkins used the Nipkow disk and transmitted the silhouette image of a toy windmill in motion, over a distance of five miles, from a naval radio station in Maryland to his laboratory in Washington, D. C., using a lensed disk scanner with a 4. Transmitting Pictures over Wireless) on 3. June 1. 92. 5 (filed 1.

March 1. 92. 2). Herbert E. Ives and Frank Gray of Bell Telephone Laboratories gave a dramatic demonstration of mechanical television on 7 April 1.

Their reflected- light television system included both small and large viewing screens. The small receiver had a 2- inch- wide by 2. The large receiver had a screen 2. Both sets were capable of reproducing reasonably accurate, monochromatic, moving images. Dell Optiplex Gx60 Drivers Windows 7. Along with the pictures, the sets received synchronized sound.

The system transmitted images over two paths: first, a copper wire link from Washington to New York City, then a radio link from Whippany, New Jersey. Comparing the two transmission methods, viewers noted no difference in quality. Subjects of the telecast included Secretary of Commerce.

Herbert Hoover. A flying- spot scanner beam illuminated these subjects. The scanner that produced the beam had a 5. The disc revolved at a rate of 1. It would be several years before any other system could even begin to compare with it in picture quality. It broadcast from the General Electric facility in Schenectady, NY.

It was popularly known as . Meanwhile, in the Soviet Union, L. As part of his thesis, on 7 May 1.

This prototype is still on display at the Takayanagi Memorial Museum in Shizuoka University, Hamamatsu Campus. His research in creating a production model was halted by the United States after Japan lost World War II. Nevertheless, the image quality of 3. UK broadcasts using the Baird system were remarkably clear.

Two of these were the 1. Compagnie des Compteurs (CDC) installed in Paris in 1. Peck Television Corp. Mechanical television, despite its inferior image quality and generally smaller picture, would remain the primary television technology until the 1.

The last mechanical television broadcasts ended in 1. United States. Electronic. In 1. 89. 7, English physicist. J. Thomson was able, in his three famous experiments, to deflect cathode rays, a fundamental function of the modern cathode ray tube (CRT).
