Hick Merlin. The Hick Merlin was a high performance small sailplane built in the United Kingdom in the mid-1930s. It was a wooden, single seat, parasol wing aircraft.  Only one was built.

Design and development
The Merlin, originally known as the Kestrel, was designed and built by W. E. Hick of the Newcastle Glider Club.  It took three years to complete, first flying on 2 February 1936 from the Club's Moat Law site.

It was a wooden single seat high performance glider with a parasol wing of three parts. The long outer panels were continuously tapered and the centre section had an uncovered strip above the fuselage, with the open cockpit not far below the underside of the wing. The wing was braced by a single lift strut on either side from the bottom of the fuselage to the outer centre section, assisted by flying wires.  The ailerons reached to the wing tips where the whole wing surface rotated, the leading edge acting as an aerodynamic balance; there were no flaps or airbrakes.

The fuselage was rounded and tapered towards the rear.  The tail surfaces had straight leading edges and curved trailing edges;  the rudder was described as "automatic".  The Merlin landed on a simple central skid which ran along the fuselage underside from the nose to below the wing trailing edge, assisted by a tailskid.

Operational history
Apart from the first flight, the activities of the Merlin seem not to have been recorded.  It was tailored around its owner and seems not to have suited other pilots, ending up on the club bonfire.

William E. Somerville. William E. Somerville (12 April 1869 – 25 September 1950) was a Scottish-American aircraft engineer.

Early life 
William E. Sommervile's father was a mechanical engineer in Scotland. Sommerville studied as a marine engineer in Scotland. Somerville immigrated to America in 1892 and worked as an electrical engineer for General Electric in Coal City, Illinois, later working for McComber Wire Rope Company. In 1907 he became mayor of Coal City, keeping the title until 1913. About the same time, he met and flew gliders designed by Octave Chanute in nearby Gary, Indiana. In 1910, Somerville started the Illinois Aero Construction Company with $250,000 in capitalization. Somerville designed a $40,000 seven-passenger aircraft believed to be one of the earliest with a forward facing engine. Somerville patented up-curled wing ends (winglets) which were the first practical application of the device in an aircraft. In 1911 Somerville leased 160 acres to build an airport and construct gliders. Somerville was sued by the Wright brothers for patent infringements, but the case was dropped.	

In 1912 Somerville hired pilot George Mestach to fly mail using his aircraft between New Orleans and Baton Rouge. Mestach was involved in a mid-air crash with a Wright biplane in Chicago later in the year that killed pilot Howard Gill but left Mestach uninjured. Mestach was flying a Borel-Morane biplane, which was used as the basis for Somerville's first monoplane, which featured wing leveling stabilizers. Sommerville changed interests, eventually becoming a captain in the Home Guard during World War I.

On 13 December 1924 a fire destroyed all of Sommerville's buildings and aircraft. Somerville hired Earl Daugherty to fly a Morane-Borel monoplane in a Barnstorming act across the Midwest. The biplane is now owned by the Canada Aviation and Space Museum. Somerville started the Somerville Engineering Company on the land once used as an airfield. He also founded the Wood-Web Porch Shade Company based on shades he saw in Germany

Somerville was also an accomplished musician, being featured as a solo clarinet with John Philip Sousa. He died at age 81 in 1950.

In 2010 Somerville was inducted into the Illinois Aviation Hall of Fame.

Cray XK6. The Cray XK6 made by Cray is an enhanced version of the Cray XE6 supercomputer, announced in May 2011.  The XK6 uses the same "blade" architecture of the XE6, with each XK6 blade comprising four compute "nodes". Each node consists of a 16-core AMD Opteron 6200 processor with 16 or 32 GB of DDR3 RAM and an Nvidia Tesla X2090 GPGPU with 6 GB of GDDR5 RAM, the two connected via PCI Express 2.0.  Two Gemini router ASICs are shared between the nodes on a blade, providing a 3-dimensional torus network topology between nodes. This means that it has 576 GB of Graphics memory and over 1500 CPU cores, several orders of magnitude more powerful than the best publicly available computer on the market.

An XK6 cabinet accommodates 24 blades (96 nodes). Each of the Tesla processors is rated at 665 double-precision gigaflops giving 63.8 teraflops per cabinet. The XK6 is capable of scaling to 500,000 Opteron cores, giving up to 50 petaflops total hybrid peak performance.

The XK6 runs the Cray Linux Environment. This incorporates SUSE Linux Enterprise Server and Cray's Compute Node Linux.

The first order for an XK6 system was an upgrade of an existing  XE6m at the Swiss National Supercomputing Centre (CSCS).

Engers station. Engers station is a through station and a former railway junction in the district of Engers in the town of Neuwied in the German state of Rhineland-Palatinate. It is on the East Rhine Railway (, Right Rhine line) and was formerly also the beginning of a line to Au (Sieg) and had a large freight yard.

History 
The station was built in the 1860s simultaneously with the Right Rhine line from Cologne to Wiesbaden. Its commissioning took place on 27 October 1869, when the Right Rhine line was extended from Niederlahnstein to Neuwied.

Initially, Engers station played only a minor transport role and only had a couple of railway employees. But this changed over the next two decades, initially with the completion of the Right Rhine line and finally in May 1884 with the completion of the Engers–Au railway to the Westerwald. The station thus became a rail transport hub, which also meant that a train depot with a roundhouse was built at the station.

In the late 19th century and well into the 20th century, a major freight yard was developed next to the passenger station, which eventually had a hump for assembling trains, as well as facilities for loading raw materials (including clay and pumice) and agricultural products. In 1912, Engers station, which was then part of the Prussian state railways, sold approximately 150,000 tickets. The track work as well as the hump and the loading  facilities still exist for the most part, but are no longer connected to the railway.

In the Second World War, Engers station and the related workshops, together with large parts of the Rhine line, were badly damaged by Allied artillery bombardments in March 1945. The rail service was resumed in August of that year. However, the station increasingly lost its former importance in the postwar period. In 1954 most of the freight and passenger trains on the Right Rhine line diverted over the line to the newly rebuilt Urmitz railway bridge and the freight yard in Engers was abandoned in the 1970s. Finally, the station lost its importance as a junction in 1989 with the closure of the line to the Westerwald.

Current operations

The old station building still exists, but is no longer used as such, because it has been sold into private ownership. Two platforms are used for passenger operations and are linked by a pedestrian underpass. It is served hourly by the Rhein-Erft-Bahn from Koblenz via Cologne to Mönchengladbach. The station is also served by three bus routes of the Verkehrsverbund Rhein-Mosel (Rhine-Moselle transport association, VRM).

List of Arduino boards and compatible systems. This is a non-exhaustive list of Arduino boards and compatible systems. It lists boards in these categories:
 Released under the official Arduino name
 Arduino "shield" compatible
 Development-environment compatible
 Based on non-Atmel processors

Where different from the Arduino base feature set, compatibility, features, and licensing details are included.

Official 
Many versions of the official Arduino hardware have been commercially produced to date:

See also list of Official Arduino Boards in wikidata

Superseded 
The following have been superseded by later and more capable versions from Arduino.

Compatible 
Although the hardware and software designs are freely available under copyleft licenses, the developers have requested that the name "Arduino" be exclusive to the official product and not be used for derivative works without permission. The official policy document on the use of the Arduino name emphasizes that the project is open to incorporating work by others into the official product.

As a result of the protected naming conventions of the Arduino, a group of Arduino users forked the Arduino Diecimila, releasing an equivalent board called Freeduino. The name "Freeduino" is not trademarked and is free to use for any purpose.

Several Arduino-compatible products commercially released have avoided the "Arduino" name by using "-duino" name variants.

Footprint-compatible 
The following boards are fully or almost fully compatible with both the Arduino hardware and software, including being able to accept "shield" daughterboards.

Special purpose compatible 
Special purpose Arduino-compatible boards add additional hardware optimised for a specific application. It is kind of like having an Arduino and a shield on a single board. Some are Shield compatible, others are not.

Industrial grade

Software-compatibility only 
These boards are compatible with the Arduino software, but they do not accept standard shields. They have different connectors for power and I/O, such as a series of pins on the underside of the board for use with breadboards for prototyping, or more specific connectors. One of the important choices made by Arduino-compatible board designers is whether or not to include USB circuitry in the board. For many Arduino tasks, the USB circuitry is redundant once the device has been programmed, so that circuitry can be placed in the cable between development PC and board, thus making each instance of the board less expensive, potentially smaller, and more power efficient.

Non-ATmega 
The following non-ATmega boards accept Arduino shield daughter boards. The microcontrollers are not compatible with the official Arduino IDE, but they do provide a version of the Arduino IDE and compatible software libraries.

Non-Arduino 
The following boards accept Arduino shield daughter boards. They do not use microcontrollers compatible with the Arduino IDE, nor do they provide an alternative implementation of the Arduino IDE and software libraries.

Gross Sky Ghost. The Gross Sky Ghost is an American high-wing, strut-braced, two-seat, glider that was designed by Frank R. Gross.

Design and development
Gross was a graduate of Akaflieg Darmstadt and the Sky Ghost was his third glider design after the Baker-McMillan Cadet and the Akron Condor. Gross's Sky Ghost was innovative for its era, in that it had tandem seating with dual controls. In the 1930s most glider flight training was accomplished by having a student fly short hops under supervision of an instructor on the ground.

The aircraft fuselage is made from welded steel tubing, with all surfaces covered in doped aircraft fabric covering. Its  span wing is mounted above the rear seat and supported by parallel lift struts. The tail is cable-braced. The cockpit is open, without a windshield. The landing gear is a conventional arrangement for fixed wing powered aircraft, rather than the more common central monowheel used on gliders. A wooden skid is also mounted on the fuselage center line. In addition to the main landing gear the aircraft has a tail skid and wing tip skids in the form of tubular loops.

The aircraft's name was derived from its appearance in flight, which was described as "eerie", due to its matte black finish.

Operational history
On at least one occasion the Sky Ghost was bungee launched from Harris Hill, New York.

The first multi-place glider flight of over two hours ever flown in the USA was completed by Gross in the Sky Ghost. It was also the first multi-place glider entered in the US Nationals, when it competed in 1932.

1957 Aqaba Valetta accident. 

On 17 April 1957, a twin-engined Vickers Valetta C.1 transport aircraft, serial number VW832, of 84 Squadron, Royal Air Force crashed and was destroyed after departing from Aqaba Airport in Jordan following wing failure due to turbulence. The crash is the deadliest air disaster in the history of Jordan.

Accident
The Valetta was returning British Army troops from Jordan to the United Kingdom following the end of the Anglo-Jordanian Treaty. The Valetta had three crew and most of the 24 passengers were from the 10th Royal Hussars. The aircraft departed Aqaba at 10:23, bound for a stop at Mafraq Airport in North Jordan and then RAF Habbaniya in Iraq. At about 10:30 the aircraft hit turbulence causing the wing to fail, the aircraft spun into the ground 20 miles North North West of Aqaba, it burned and was destroyed killing all on board.

The bodies were returned to RAF Habbaniya and were buried with full military honours in the RAF/CWGC cemetery on 27 April 1957. The bodies lie in Plot 5 Row B Graves 1–7. The personnel who died were 3 RAF crew, 18 10th Hussars troops, 5 REME soldiers and 1 Army Catering Corps soldier.

Investigation
The Board of Inquiry found the accident was due to the failure of the port main spar of the outer wing which had resulted in the disintegration of the wing round the fracture and damage to the rear fuselage and tail. The board also said it found that spar failure was due to over-stressing and they suggested this was due to the extreme air turbulence which was known to have existed in the area at the time. The board said they had found no sign of a fatigue failure.

Electronic-warfare aircraft. An electronic-warfare aircraft is a military aircraft equipped for electronic warfare (EW), that is, degrading the effectiveness of enemy radar and radio systems by using radar jamming and deception methods.

In 1943, British Avro Lancaster aircraft were equipped with chaff in order to blind enemy air defence radars. They were supplemented by specially-equipped aircraft flown by No. 100 Group RAF, which operated modified Halifaxes, Liberators and Fortresses carrying various jammers such as Carpet, Airborne Cigar, Mandrel, Jostle, and Piperack.

Glenda Schroeder. Glenda Schroeder is an American software engineer noted for implementing the first command-line user interface shell and publishing one of the earliest research papers describing electronic mail systems while working as a member of the staff at the MIT Computation Center in 1965.

Biography
Early operating system command-line interfaces were implemented as part of resident monitor programs, and could not easily be replaced. In 1964, MIT Computation Center staff member Louis Pouzin developed the RUNCOM tool for executing command scripts while allowing argument substitution. Pouzin coined the term "shell" to describe the technique of using commands like a programming language, and wrote a paper describing how to implement the idea in the Multics operating system. Pouzin returned to his native France in 1965, and Schroeder developed the first Multics shell with the assistance of an unnamed man from General Electric. Schroeder's Multics shell was the predecessor to the Unix shell, which is still in use today.

Working with Pat Crisman and Louis Pouzin, she also described an early email system called "MAIL" to allow users on the Compatible Time-Sharing System (CTSS) at MIT to send notifications to others about backups of files. Each user's messages would be added to a local file called "MAIL BOX", which would have a “private” mode so that only the owner could read or delete messages. The proposed uses of the proto-email system were for communication from CTSS to notify users that files had been backed up, discussion between authors of CTSS commands, and communication from command authors to the CTSS manual editor. The service only made it possible to leave messages for the other users on the same computer. The idea to allow users to send messages between computers was developed later by Ray Tomlinson in 1971.
