COM file

A COM file is a type of simple executable file. On the Digital Equipment operating systems of the 1970s, .COM was used as a filename extension for text files containing commands to be issued to the operating system (similar to a batch file). With the introduction of CP/M (a microcomputer operating system), the type of files commonly associated with COM extension changed to that of executable files. This convention was later carried over to MS-DOS. Even when complemented by the more general .exe file format for executables, the compact COM files remain viable and frequently used in MS-DOS.

The .COM file name extension has no relation to the .com (for "commercial") top-level Internet domain name. However, this similarity in name has been exploited by malicious computer virus writers.

MS-DOS binary format

The COM format is the original binary executable format used in CP/M and MS-DOS. It is very simple; it has no header (with the exception of CP/M 3 files), and contains no standard metadata, only code and data. This simplicity exacts a price: the binary has a maximum size of 65,280 (FF00h) bytes (256 bytes short of 64 KB) and stores all its code and data in one segment.

56.com

56.com is one of the largest video sharing websites in China, where users can upload, view and share video clips.

A fully owned subsidiary of Sohu, the company is headquartered in Tianhe District, Guangzhou, Guangdong.

The domain 56.com attracted at least 3.2 million visitors annually by 2008 according to a Compete.com survey.

Access to the Chinese online video provider 56.com was suspended since 18:00 on June 3, 2008. 56.com made an explanation at 10:00 on June 4, 16 hours after the website's access was stopped, and said that the website had experienced a server failure and was being repaired, but it did not give a clear time for when the site's services would be fully resumed. Some media, such as Hexun.com and Sina.com, reported that as 56.com had frequently violated relevant government rules with its video content, it had therefore been issued a warning by the government and might be closed for a few days. However, this was denied by 56.com. By July 11, 2008, 56.com was back and operational.

FiveThirtyEight

FiveThirtyEight, sometimes referred to as 538, is a website that focuses on opinion poll analysis, politics, economics, and sports blogging. The website, which takes its name from the number of electors in the United States electoral college, was founded on March 7, 2008, as a polling aggregation website with a blog created by analyst Nate Silver. In August 2010 the blog became a licensed feature of The New York Times online. It was renamed FiveThirtyEight: Nate Silver's Political Calculus. In July 2013, ESPN announced that it would become the owner of the FiveThirtyEight brand and site, and Silver was appointed as editor-in-chief. The ESPN-owned FiveThirtyEight began publication on March 17, 2014. In the ESPN era, the FiveThirtyEight blog has covered a broad spectrum of subjects including politics, sports, science, economics, and popular culture.

During the U.S. presidential primaries and general election of 2008, the site compiled polling data through a unique methodology derived from Silver's experience in baseball sabermetrics to "balance out the polls with comparative demographic data." He weighted "each poll based on the pollster's historical track record, sample size, and recentness of the poll".

WSYR-TV

WSYR-TV is the ABC-affiliated television station for Central New York State that is licensed to Syracuse. It broadcasts a high definition digital signal on UHF channel 17 from a transmitter on Sevier Road in Pompey. The station can also be seen on Time Warner channel 9 and in high definition on digital channel 1240. Owned by Nexstar Broadcasting Group, it has studios on Bridge Street (NY 690) in East Syracuse.

History

Channel 9 was the last of Syracuse's major network affiliates to sign on, doing so September 9, 1962 after a channel shuffle involving rival WHEN-TV and Rochester's WROC-TV allowed a third analog VHF station in Syracuse. The original call letters were WNYS-TV (now assigned to Syracuse's MyNetworkTV affiliate). It signed-on under the ownership of a group of local investors. The station has always been an ABC affiliate. Channel 9's original studios were located in the basement of Shopping Town Mall on Erie Boulevard in DeWitt.

Fire overtook WNYS-TV's studios in the basement of the Shopping Town Mall in DeWitt in April 1967 forcing the station to temporarily move to WCNY-TV's studios in Liverpool until its facilities were rebuilt. In 1969, then-owner W.R.G. Baker Television Corporation applied for a WNYS-TV translator on channel 7, W07BA; this facility, serving Syracuse and nearby Nedrow, came on the air in 1972. W07BA, which later moved its second city of license to DeWitt, remained a repeater of channel 9 until 2014; its license was canceled on March 24, 2014. The station was purchased by The Outlet Company in 1971, and was sold in 1978 to WNYS Acquisition Corp., which was a joint partnership of Coca Cola's New York bottling division and former Washington Post president Larry H. Israel. The call sign was then changed to WIXT-TV with "IX" standing for Roman numeral 9. The Ackerley Group bought the station in 1982. The station moved to its current location on Bridge Street in 1985.

891 ABC Adelaide

891 ABC Adelaide (call sign: 5AN) is the ABC Local Radio station for Adelaide. It is broadcast at 891 kHz on the AM band.

History

5AN started transmitting on 15 October 1937 with equipment located in the central telephone exchange, and a radio mast located in Post Office Place. The station transmitter moved to Brooklyn Park, the site of 5CL on 4 May 1944. The radio mast was moved from the east side of the building to the south side to make way for an airport road in 1952. The airport made the transmitter site inconvenient so it was moved to the Pimpala Transmitting Station, at the corner of Sherriffs and Hillier Roads, Reynella, and opened on 20 September 1961 by Postmaster-General C W Davidson.

The ABC radio staff relocated to an eight story building in Collinswood in 1974. In the 1980s the radio manager was David Hill. In 2000 the 5AN branding was replaced with "891 ABC Adelaide".

The power level of 5AN was upgraded to 50 kW in the early 1950s. The transmitter for this was housed in the same building as for 5CL. The transmitter was manufactured by STC. The final stage of the transmitter contained three parallel 3J/261E air cooled triodes running in class C amplifier at 90% efficiency. These were driven by a class B modulator with the same type of valves.
