BHP Whyalla DH class. The BHP Whyalla DH class were a class of diesel locomotives built by Walkers Limited, Maryborough for the BHP's Whyalla Steelworks between 1962 and 1968.

History
In 1962 three locomotives were purchased by BHP for use at its new Whyalla Steelworks. Initially used on construction trains until the facility opened in 1964. A further two were delivered in 1965. All were built for use on the standard gauge. In March 1968 a sixth was purchased for use on the narrow-gauge line between Hummock Hill and the blast furnaces.

All six members of this class have been scrapped with DH1 being the last to be scrapped, having been transferred to Australian Southern Railroad when it took over OneSteel's rail operations in 2000.

Junk raft. A junk raft is a type of home-built watercraft made of plastic bottles or other recycled materials constructed by artists and community-minded groups organizing recreational flotillas, or by environmentally concerned individuals seeking to draw attention to the problem of floating debris and the need for recycling. It can also be an improvised small, functional watercraft from readily available materials.

The JUNK Raft Project was organized by Dr. Marcus Eriksen, Joel Paschal and Anna Cummins in Long Beach, California in 2008, to bring attention to the issue of plastic pollution in the Great Pacific Garbage Patch. The project was launched with the Algalita Marine Research Foundation, after founder Charles J. Moore encountered the patch in 1997. Organizers hoped to "creatively raise awareness about plastic debris and pollution in the ocean," specifically the Great Pacific Garbage Patch trapped in the North Pacific Gyre, by sailing 2,600 miles across the Pacific Ocean on a  raft made from an old Cessna 310 aircraft fuselage and six pontoons filled with 15,000 old plastic bottles. Crewed by Dr. Marcus Eriksen of the Foundation and film-maker Joel Paschal, the raft set off from Long Beach, California on 1 June 2008, arriving in Honolulu, Hawaii on 28 August 2008. On the way, they gave valuable water to record-holding ocean rower Roz Savage, also on an environmental awareness voyage, when her supplies dwindled.

The construction of the JUNK Raft began in April 2008 and was finished the following month. The huge undertaking of constructing a seaworthy raft from "junk" was aided by volunteers from the environmental education programs of Bell Elementary School, Green Ambassadors, Muse Elementary School, Santa Monica High School, and Westbridge School for Girls. The volunteers lent a hand by cleaning bottles, fastening bottle caps, and stuffing them into the recycled fisherman's net pontoon forms.

Test article (aerospace). A test article or pathfinder is a version of a spacecraft or related vehicle or equipment, built as a platform to perform testing on particular portions of a spaceflight regime. Test articles are built to the specifications necessary to replicate particular conditions and behaviors that are to be validated. Test articles may be built for flight testing or for non-flight testing.  

For space agencies with extensive flight certification procedures, they may be built without the certification and quality control steps taken with the versions intended for flight.  Test articles are more complete than a boilerplate.

Overview
Some test articles are theoretically able to be modified and upgraded to flight-ready status.  Of the 136 Space Shuttle external fuel tanks produced, one was retained as a test article.  The contractor producing the tanks stated that that tank could be refurbished for flight use if necessary.

Test articles are often displayed in museums because of their accuracy.  Museums may refurbish test articles to match more modern configurations.  This was completed on the Hubble Space Telescope Structural Dynamic Test Vehicle on display at the National Air and Space Museum where this 1976 version of the vehicle was removed from display and upgraded in 1996 by the Smithsonian, Lockheed, and NASA to incorporate changes made on the on-mission version of the Hubble Space Telescope over several servicing missions.

SS Gulfwave. SS Gulfwave was a Gulf Oil Corporation tanker that operated from 1937 to 1956. She was torpedoed during World War II. but returned to service after repairs. From 1956 to 1959 she operated as the Liberian Michael J.

Construction
Bethlehem Steel Company at Sparrows Point, Maryland. She was launched on 9 October 1937 as the third of four tankers built at Sparrows Point for Gulf Oil. The construction made greater use of welding than in the previous two tankers of the series. She was delivered to Gulf Oil on 1 December 1937.

Characteristics
Gulfwave was  in length overall,  in registered length,  in beam, and had a design draft of . Propulsion was by a set of General Electric double-reduction geared turbines, developing about , driving a single  propeller for a maximum speed of about .

Service history
Gulfwave operated with the Gulf Oil fleet until taken by the War Shipping Administration for World War II service on 20 April 1942. Gulf Oil subsequently operated her under an agreement with the United States Army, revised to a time charter on 29 June 1944. After the war, the ship returned to company operations on 20 November 1945.

On 1 March 1943 the ship was torpedoed by the Imperial Japanese Navy submarine  under the command of Commander Kinzo Tonozuka in the New Hebrides south of Tonga at . Gulfwave suffered no casualties among her merchant mariners or United States Navy Armed Guard personnel, and she arrived at Suva in Fiji under her own power. After temporary repairs at Suva, Gulfwave arrived at Pago Pago in American Samoa on 29 March 1943 for further repairs. She departed Pago Pago on 13 May 1943 bound for Hawaii. Permanent repairs were made at Portland, Oregon.

Gulfwave was sold to Liberian interests in January 1956, renamed Michael J., and was scrapped in 1959.

I.Ae. 41 Urubú. The I.Ae.41 Urubú was a two-seat flying wing tailless glider, built in Argentina by the Fábrica Militar de Aviones (FMA) in the 1950s.

History 
In 1951 some airclubs requested from the Department of Aeronautics (Secretaría de Aeronáutica) that a side-by-side two-seater sports glider should be built. Its development was assigned to the Instituto Aerotécnico (I.Ae.), in Cordoba.
The design team was led by Professor Reimar Horten, who was a pioneer in the design of tailless flying wing planes. His project H.XVc was submitted to the Department of Aeronautics, and was assigned the denomination I.Ae.41 "Urubú" (meaning "owl" in mapudungun). Production at the FMA was limited to five planes, and the first flight was in 1953.

In September 1956, after a proposal from the "Dirección de Fomento de la Aviación Civil" (Civil Aviation Directorate), a crossing of the Andes Mountain Range ("Cordillera de los Andes") with sailplanes was attempted. The gliders chosen were the I.Ae.41 Urubú, towed by a Morane-Saulnier, and a Slingsby Sky glider, towed by  a Stearman. Pilots Hans Scheidhauer (Urubú) and Claudio Dori (Sky) flew from San Carlos de Bariloche (Argentina) to Paraje Ensenada (Chile). The flight lasted three hours, crossing over: Cerro Otto, Cerro Catedral, the Tristeza branch of Nahuel Huapi lake, Puerto Blest, Cerro Tornador, Laguna Fría, Lanín Volcano, Cerro El Puntiagudo and Cerro Osorno.

Description 
The I.Ae 41 was a wooden aircraft, similar in general to the preceding I.Ae. 34 Clen Antú but with a spacious twin-seat side-by-side cockpit. Its design incorporated lessons learnt from its predecessor and it had improved aerodynamics, showing better handling in turbulent conditions. Its tandem landing gear had more efficient shock absorbers.

Surviving aircraft 
A surviving aircraft has been restored, and is displayed at the Argentine Air Force’s Museo Nacional de Aeronáutica de Argentina, located at Morón Airport.

Next Steps in Signaling. Next Steps in Signaling (NSIS) was an Internet Engineering Task Force working group focusing on the design of a next generation signaling protocol framework and protocol specifications.

The NSIS working group was chartered in late 2001 to work on a replacement for Resource Reservation Protocol (RSVP).   Chairs included Jukka Manner and Martin Stiemerling.  The overall framework of NSIS was presented in 2005.  In 2006, the group submitted the first protocol specification for approval by the Internet Engineering Steering Group (IESG).  In October 2010, the actual protocol specifications were finally approved and released within the Request for Comments (RFC) series.
The work concluded in 2011.

The NSIS protocol suite includes three primary protocols:
 The General Internet Signalling Transport protocol (GIST)
 The QoS signaling protocol QoS NSLP 
 The NAT/Firewall signaling protocol NAT/FW NSLP 

The QoS NSLP seeks to replace the Resource Reservation Protocol (RSVP) for signaling resource reservations to Internet routers.

The NAT/Firewall NSLP provides a means to talk to network middleboxes, such as firewalls NATs, to punch holes and set up IP address mappings.

William Pedley. William Everard Pedley (16 June 1858 – 9 July 1920) was an English civil engineer and cricketer who played first-class cricket for Sussex. After emigrating to the United States he became a well known irrigation engineer in Southern California. He gave his name to the community of Pedley, California, now a neighborhood within the city of Jurupa Valley, California.

England
Pedley was born at Stubbing Court, Wingerworth, Derbyshire, the son of Thomas Humphrey Pedley and his wife Mary Gully, daughter of John Gully. He joined the Royal Engineers and in 1877 became a member of the Institution of Civil Engineers. In 1879 Pedley played two matches for Sussex against Kent and Surrey. Against Kent he took 7 for 36 and was not out on 16 in his second innings to help Sussex to victory. He also played for the Royal Engineers and Gentlemen of Sussex. Pedley next appeared playing for his native Derbyshire in the 1888 season.

California
Pedley went to America where he was manager of the San Jacinto Land Company, who developed part of the Sobrante de San Jacinto land grant at Riverside, California.  He was the designer, builder, and engineer of the irrigation system that was installed. He gave his name to the settlement of Pedley, California in 1903 or 1904 when the Union Pacific Railroad Company installed a switch and a railroad station at the location. His name was also given to the nearby Pedley Hills, a low lying mountain range, also within the Jurupa Valley city limits.

Sports
In Cricket, Pedley was a right-hand batsman and played four innings in two first-class matches with an average of 15 and a top score of 16 not out. He was a right-arm medium pace bowler and took 10 first-class wickets at an average of 13.80 and a best performance of 7 for 36.

In California Pedley became a regular Polo player on the local fields and a member of the Riverside polo team, keeping his own stable of polo horses. His son, Eric became a professional player and a three-time winner of the U.S. Open Polo Championship.

Death
Pedley died in Los Angeles, California at the Good Samaritan Hospital. He was 62. While on a road trip he took ill and was taken to the Los Angeles hospital where he was diagnosed with ptomaine poisoning, and died shortly thereafter. His funeral services were held at the All Saints Episcopal Church in Riverside, and he was interred at the Olivewood Cemetery.

Perite. Perite is a mineral that has a general chemical formula of PbBiO2Cl. The name is given for Per Adolf Geijer, a Swedish economic geologist with the Geological Survey of Sweden, who discovered the mineral in 1960 outside of Långban, Sweden. Perite is orthorhombic, space group Cmcm {C2/m 2/c 21/m}. In terms of its optical properties, Perite is anisotropic which means the velocity of light varies depending on direction through the mineral (i.e. it is birefringent).  Its calculated relief is 1.45–1.461, which is moderate. It is colorless in plane polarized light, and it is weakly pleochroic. Perite is found in areas near igneous extrusions in places like the Western United States, Southern Australia, and scattered around Europe.

Crystallography 
Perite belongs to the orthorhombic crystal system, and has the properties of 2/m 2/m 2/m crystal class. Therefore, perite has three mirror planes and three twofold rotation axes.

Vladimirite. Vladimirite is a rare calcium arsenate mineral with a formula of Ca5(HAsO4)2(AsO4)2·5H2O.  It is named after the Vladimirovskoye deposit in Russia, where it was discovered in the 1950s.

Vladimirite is monoclinic-prismatic, which means crystallographically, it contains three axes of unequal length and the angles between two of the axes are 90 degrees, and one is less than 90 degrees.  It belongs to the space group P21/c.  The mineral also has an orthorhombic polytype.  In terms of its optical properties, vladimirite is anisotropic which means the velocity of light varies depending on direction through the mineral.  Relief is a diagnostic characteristic of a mineral in plane polarized light that refers to the various ways different minerals "stand out".  Vladimirite's calculated relief is 1.65-1.661, which is moderate.  It is colorless in plane polarized light, and it is weakly pleochroic. Pleochroism is the variety of colors under plane polarized light displayed by crystals at various angles.

Occurrence
Vladimirite was first described in 1953 at two deposits in Russia, the Khovu-Aksy nickel-cobalt deposit, Tuva Republic, and the Vladimirovskoye cobalt deposit, Altai Mountains, Altaiskii Krai, Siberia. 
It is a secondary mineral in the oxidized zone of arsenic-bearing ore deposits. It occurs with picropharmacolite, erythrite and aragonite. It has been reported from the Richelsdorf Mountains, Hesse, Germany; the Bou Azzer district, Morocco and the Mohawk mine, Keweenaw County, Michigan.

William John (Medal of Honor). William F. John (October 23, 1844 – 1927) was a Union Army soldier during the American Civil War. He received the Medal of Honor for gallantry during the Siege of Vicksburg on May 22, 1863.

Union assault
On May 22, 1863, General Ulysses S. Grant ordered an assault on the Confederate heights at Vicksburg, Mississippi. The plan called for a storming party of volunteers to build a bridge across a moat and plant scaling ladders against the enemy embankment in advance of the main attack.
The volunteers knew the odds were against survival and the mission was called, in nineteenth century vernacular, a "forlorn hope". Only single men were accepted as volunteers and even then, twice as many men as needed came forward and were turned away. The assault began in the early morning following a naval bombardment.

The Union soldiers came under enemy fire immediately and were pinned down in the ditch they were to cross. Despite repeated attacks by the main Union body, the men of the forlorn hope were unable to retreat until nightfall. Of the 150 men in the storming party, nearly half were killed.  Seventy-nine of the survivors were awarded the Medal of Honor.

Medal of Honor citation
For gallantry in the charge of the volunteer storming party on 22 May 1863.

Explorer-class general-purpose vessel. The Explorer class was a two-ship class of general purpose vessels of the Royal Australian Navy that served between 1960 and 1995.

Design
The Explorer class was a two-ship class of general purpose vessels built for the RAN. The ships had a displacement of 207 tons at standard load and 260 tons at full load. Each was  long between perpendiculars and  long overall, had a beam of , and a draught of . Propulsion machinery consisted of GM diesels, which supplied  to the two propeller screws, and allowed the vessel to reach . The ship's company consisted of 14 personnel. The ship's armament of light weapons (usually .50 calibre machine guns) were only fitted as needed.

The two vessel,  and , were built by Walkers Limited of Maryborough, Queensland. Both were laid down in 1959, and were commissioned into the RAN in 1960.

Operational history
The Explorers' primary roles were hydrographic survey and reservist training, among other duties.

In December 1982, both vessels were decommissioned. Despite this, they remained active in training until the mid-1990s.

Cornell University Programming Language. Cornell University Programming Language (also called CUPL) is a procedural computer
programming language developed at Cornell University in the late 1960s.

CUPL was based on an earlier Cornell-developed programming language, CORC.
It was used to teach introductory computer programming classes.

CUPL was developed by Richard W. Conway, W. L. Maxwell, G. Blomgren, Howard Elder, H. Morgan, C. Pottle, W. Riddle, and Robert Walker.
CUPL had a very simple syntax similar to BASIC and to PL/I.
The processor was designed to offer extensive error correction and diagnostic capabilities.
This would allow student programs to execute even if they contained minor syntax errors.
The compiler also included spelling correction capabilities so that if a variable name is referenced only once, the compiler would assume that it was a misspelling of some other intended name.

CUPL also offered an extensive set of matrix operations and offered dynamic run-time memory allocation. At the time, Cornell's computer was an IBM System/360 Model 40 batch processing system with only 64 KB of core memory. CUPL was able to process a large number of student programs quickly by remaining resident in core memory, but the compiler occupied 58 KB of memory, leaving only a small amount for the program code and variable storage.

Derivative projects
Additional computer language projects grew out of CUPL. The CUPL compiler was reworked to implement a subset of the PL/I programming language, called PL/C.  PL/C retained the diagnostic and error correction features of CUPL.

Audio CUPL was an implementation to accept verbal CUPL statements spoken by the programmer. Each programmer trained the system by first speaking a standard set of CUPL vocabulary words for reference.

Retrocomputing implementation
There is an implementation of CUPL and CORC in modern C for Unix-like systems that includes both transcriptions of the original manuals and a chrestomathy of programs in these languages.  It is available at the Retrocomputing Museum.
