Ira Gershwin was an American lyricist who collaborated with his younger brother, composer George Gershwin, to create some of the most memorable songs in the English language of the 20th century. With George he wrote more than a dozen Broadway shows, featuring songs such as "I Got Rhythm", "Embraceable You", "The Man I Love" and "Someone to Watch Over Me", he was responsible, along with DuBose Heyward, for the libretto to George's opera Porgy and Bess. The success the Gershwin brothers had with their collaborative works has overshadowed the creative role that Ira played, his mastery of songwriting continued, after the early death of George. He wrote additional hit songs with Kurt Weill, Harry Warren and Harold Arlen, his critically acclaimed 1959 book Lyrics on Several Occasions, an amalgam of autobiography and annotated anthology, is an important source for studying the art of the lyricist in the golden age of American popular song. Gershwin was born at 242 Snediker Avenue in Brooklyn, the oldest of four children of Morris and Rose Gershovitz, who were Russian Jews, born in St Petersburg, who had emigrated to the US in 1891.

Ira's siblings were George and Frances. Morris changed the family name to "Gershwine". Shy in his youth, Ira spent much of his time at home reading, but from grammar school through college he played a prominent part in several school newspapers and magazines, he graduated in 1914 from Townsend Harris High School, a public school for intellectually gifted students, where he met Yip Harburg, with whom he enjoyed a lifelong friendship and a love of Gilbert and Sullivan. He dropped out; the childhood home of Ira and George Gershwin was in the center of the Yiddish Theater District, on the second floor at 91 Second Avenue, between East 5th Street and East 6th Street. They frequented the local Yiddish theaters. While George began composing and "plugging" in Tin Pan Alley from the age of 18, Ira worked as a cashier in his father's Turkish baths, it was not until 1921. Alex Aarons signed Ira to write the songs for his next show, Two Little Girls in Blue produced by Abraham Erlanger, along with co-composers Vincent Youmans and Paul Lannin.

So as not to appear to trade off George's growing reputation, Ira wrote under the pseudonym "Arthur Francis", after his youngest two siblings. His lyrics were well received, allowing him to enter the show-business world with just one show; the same year, the Gershwins collaborated for the first time on a score. It was not until 1924 that Ira and George teamed up to write the music for what became their first Broadway hit Lady, Be Good. Once the brothers joined forces, their combined talents became one of the most influential forces in the history of American Musical Theatre. "When the Gershwins teamed up to write songs for Lady, Be Good, the American musical found its native idiom." Together, they wrote the music for four films. Some of their more famous works include "The Man I Love", "Fascinating Rhythm", "Someone to Watch Over Me", "I Got Rhythm" and "They Can't Take That Away from Me", their partnership continued until George's sudden death from a brain tumor in 1937. Following his brother's death, Ira waited nearly three years before writing again.

After this temporary retirement, Ira teamed up with accomplished composers such as Jerome Kern. Over the next 14 years, Gershwin continued to write the lyrics for many film scores and a few Broadway shows, but the failure of Park Avenue in 1946 was his farewell to Broadway. As he wrote at the time, "Am reading a couple of stories for possible musicalization but I hope I don't like them as I think I deserve a long rest."In 1947, he took 11 songs George had written but never used, provided them with new lyrics, incorporated them into the Betty Grable film The Shocking Miss Pilgrim. He wrote comic lyrics for Billy Wilder's 1964 movie Kiss Me, although most critics believe his final major work was for the 1954 Judy Garland film A Star Is Born. American singer and musical historian Michael Feinstein worked for Gershwin in the lyricist's latter years, helping him with his archive. Several lost musical treasures were unearthed during this period, Feinstein performed some of the material. Feinstein's book The Gershwins and Me: A Personal History in Twelve Songs about working for Ira, George and Ira's music was published in 2012.

According to a 1999 story in Vanity Fair, Ira Gershwin's love for loud music was as great as his wife's loathing of it. When Debby Boone—daughter-in-law of his neighbor Rosemary Clooney—returned from Japan with one of the first Sony Walkmans, Clooney gave it to Michael Feinstein to give to Ira, "so he could crank it in his ears, you know, and he said,'This is wonderful!' And he called his broker and bought Sony stock!" Three of Ira Gershwin's songs were nominated for an Academy Award for Best Original Song, though none won. Along with George S Kaufman and Morrie Ryskind, he was a recipient of the 1932 Pulitzer Prize for Drama for Of Thee I Sing. In 1988 UCLA established The Georg

Cisco Meraki is a cloud-managed IT company headquartered in San Francisco, California. Their products include wireless, security, enterprise mobility management and security cameras, all centrally managed from the web. Meraki was acquired by Cisco Systems in December 2012. Meraki was founded by Sanjit Biswas and John Bicket, along with Hans Robertson; the company was based in part on the MIT Roofnet project, an experimental 802.11b/g mesh network developed by the Computer Science and Artificial Intelligence Laboratory at the Massachusetts Institute of Technology. Meraki was funded by Sequoia Capital; the organization started in Mountain View, before relocating to San Francisco. Meraki employed people. In 2007, Meraki selected San Francisco for their community-based Free the Net campaign, they started putting gateway devices in the Lower Haight neighborhood to provide Internet access and giving away repeaters. In the first year of the project, the growth of the network was in the Mission District.

By October 2007, they estimated 20,000 distinct users connected and about 5 terabytes of data transferred in this network. In July 2008, Meraki said 100,000 people in San Francisco used its "Free the Net" service. Since Meraki discontinued this public service, though many access points remain active, but with no connection to the Internet. On November 18, 2012, Cisco Systems announced. On August 3, 2017, the engineering team made changes to the North American object storage service. Cisco stated that the change was due to the application of "an erroneous policy"; the data loss affected media files uploaded by customers. Data, lost included: Systems Manager – Custom enterprise apps and contact images. Meraki Communications – IVR audio files, hold music, contact images and VM greetings. Wireless Device Dashboard – Custom floor plans, device placement photos, custom logos used for interface branding and reports and custom splash themes. On August 7 Meraki announced. On August 9 customers were informed that recovery efforts were still underway but that they "do not expect to be able to recover most assets".

The Zeppelin-Staaken E-4/20 was a revolutionary four-engine all-metal passenger monoplane designed in 1917 by Adolf Rohrbach and completed in 1919 at the Zeppelin-Staaken works outside Berlin, Germany. The E-4/20 was the first four-engine, all-metal stressed skin heavier-than-air airliner built. At a time when most aircraft were small, single-engine biplanes made of wood and canvas, the E-4 was a large, all-metal, four-engine, stress-skinned, semi-monocoque, cantilevered-wing monoplane, with an enclosed cockpit, accommodation for 18 passengers plus a crew of five, including two pilots, a radio operator, an engineer and a steward, as well as radio-telegraph communications, a toilet, a galley and separate baggage and mail storage. With a maximum speed of 143 mph, cruising speed of 211 km/h, a range of about 1,210 km, a loaded weight of 8,500 kg, it outperformed most other airliners of its day; the E-4 included numerous innovations, including its all-metal monocoque construction, onboard facilities such as lavatory and radio communications, its notable and sturdy monoplane load-bearing box-girder wing constructed of dural metal which formed both the wing's main girder and the structure of the wing itself.

Skinned with thin sheets of dural metal to give the aerofoil shape necessary for a wing, the girder section wing had fabric covered leading and trailing edges attached to it. This superb and innovative wing was self-supporting; the E-4 was completed in 1919 and test flown between 30 September 1920 and 1922 when it was broken up on the orders of the Inter-Allied Commission. The Zeppelin-Staaken E-4/20 was a product of the innovative Zeppelin Airship company. Count Ferdinand von Zeppelin, founder of the Luftschiffbau Zeppelin GmbH was himself a major aeronautical innovator, creator of the groundbreaking giant aluminium alloy framed Zeppelin lighter than air dirigible airships and developer of a series of R-Planes. Zeppelin was one of the first aeronautical pioneers to apply stringent scientific principals to the design of aircraft, focusing on issues like power-to-weight ratios of engines and using the new metal alloy aluminium for structural components. Zeppelin heard of the success in Russia of Igor Sikorsky's pioneering 4-engined Le Grand and Ilya Muromets aircraft.

From the outbreak of war in 1914 the 4-engined Ilya Muromets class of aircraft were used as heavy bombers. The German government saw the potential for large strategic bombers and issued a design standard, used by several manufacturers to produce Riesenflugzeuge or R-Planes; the most successful design and manufacturing company of R-Planes was Zeppelin, the only company to manufacture them in series production, the R-VI. Adolf Rohrbach went on to found his own aircraft company, Rohrbach Metall-Flugzeugbau where he designed and built a number of innovative civil all-metal airliners, such as the Ro-VIII trimotor as well as some groundbreaking flying boats; the Smithsonian Institution's "Airspace Magazine" suggested that Rohrbach could have been Germany's Boeing or Douglas but that the Inter-Allied Commission deemed the E-4/20 too much of a threat as a potential bomber to be allowed to go into serial production and ordered its destruction declining offers to sell it to allied countries. The 1932 Armstrong Whitworth Atalanta used a similar configuration, differing in construction details and more powerful engines.
