Jinx Debugger. Jinx was a concurrency debugger that deterministically controlled the interleaving of workloads across processor cores, focusing on shared memory interactions. Using this deterministic approach, Jinx aimed to increase the frequency of occurrence of elusive shared memory bugs, sometimes called Heisenbugs.  Jinx is no longer available. Corensic, the company that was developing Jinx, was bought by F5 Networks and the Jinx project was cancelled.

Jinx worked by dynamically building a set of potential interleavings (i.e. alternate eventualities, or execution scenarios, that will occur under some future condition) that are most likely to result in concurrency faults, and quickly tested those execution paths to surface concurrency problems such as deadlocks, race conditions and atomicity violations that are found in multiprocessing applications.

Unlike model checkers, Jinx did not require the specification of a model. Unlike dynamic and static code analysis methods, Jinx was notable in that it produced no false positives (spurious bug reports). This was because Jinx tested the scenarios that are likely to be bugs, as opposed to just inferring those scenarios by analyzing source code or observing the execution of a program.

Jinx was implemented as a hypervisor, giving it the ability to observe the effects of all elements of the software environment on thread interleaving. Jinx operated independently of any programming language or threading libraries or tools.

Jinx was developed by a (now defunct) company named Corensic in Seattle, Washington based on research performed at the University of Washington and initially presented at the ASPLOS conference of 2009.

Henry Ronald Godfrey. Ronald Godfrey (1887–1968), full name Henry Ronald Godfrey, was an English motor car design engineer of the first half of the 20th century possibly best known for his successful Singer-engined  H R G thoroughbred sports cars built between 1935 and 1956.

Apprenticeship
Born near London, Ron met Archie Nash at London's Finsbury Technical School and after obtaining his City & Guilds diploma in Mechanical Engineering he completed an apprenticeship at Willans & Robinson in Rugby, Warwickshire where the slightly younger Archie soon followed him to do the same training.

G N
Godfrey and Nash then got together to produce the GN cycle car. A light-weight 90 degree Vee-twin-cylinder car first sold in 1911, it stayed in production through 1922. Ron Godfrey's major contribution was his design of the engine and chain transmission.

H R Godfrey Motors
When Archie Nash left the company in 1922 to form Frazer-Nash Godfrey left to provide a repair business H R Godfrey Motors to supply GN spares. They also offered rebuilds. This enterprise formed the basis of his partnership with Stuart Proctor, with whom he formed Godfrey-Proctor. Continuing the servicing of GN's, they produced their own car based on the Austin Seven, but the venture was unsuccessful, with only about 10 cars produced by the time the company ceased trading in 1928.

Nash & Thompson
In 1929 Ron joined a new partnership with Archie Nash in Kingston-upon-Thames, Nash & Thompson. It was described as contractors and armament engineers for the Admiralty and the Air Ministry. Archie designed the hydraulic gun turret that was to be widely used in World War II. In 1935 Archie Nash took this business into Parnall Aircraft and Ron Godfrey moved to a new enterprise.

H R G Engineering

In 1935, having raced at Brooklands, Ron Godfrey formed HRG Engineering (initial letters Halford Robins Godfrey) with Major E J "Ted" Halford and Guy Herbert Robins, who was previously with Trojan. H R G was based in Norbiton, with the first prototype shown at the end of 1935. Fully established in 1936, the company produced cars until 1956, and then reverted to development engineering work for others, before ceasing trading in 1966.

Their H R G car was a small true sports car in the vintage tradition sold at a realistic price. The prototype used a Meadows ED engine with a strengthened crankshaft. It could exceed 85 mph and handled excellently on the road. From 1939 the Meadows engine was replaced with a 1½ litre overhead camshaft Singer engine. When Ronald retired he had a very advanced new car on the drawing board but it was never put into production.

British Automobile Racing Club
H R Godfrey was a founder member of the British Automobile Racing Club.

Ron Godfrey retired in 1958 to a nearby water mill which he took great pleasure in rebuilding. He died in 1968.

Internal fixation. Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone, a concept that dates to the mid-nineteenth century and was made applicable for routine treatment in the mid-twentieth century. An internal fixator may be made of stainless steel, titanium alloy, or cobalt-chrome alloy.

Types of internal fixators include:
 Plate and screws
 Kirschner wires
 Intramedullary nails

Open reduction

Open reduction internal fixation (ORIF) involves the implementation of implants to guide the healing process of a bone, as well as the open reduction, or setting, of the bone. Open reduction refers to open surgery to set bones, as is necessary for some fractures. Internal fixation refers to fixation of screws and/or plates, intramedullary rods and other devices to enable or facilitate healing. Rigid fixation prevents micro-motion across lines of fracture to enable healing and prevent infection, which happens when implants such as plates (e.g. dynamic compression plate) are used. ORIF techniques often are used in cases involving serious fractures such as comminuted or displaced fractures or, in cases where the bone otherwise would not heal correctly with casting or splinting alone.

Risks and complications may include bacterial colonization of the bone, infection, stiffness and loss of range of motion, non-union, mal-union, damage to the muscles, nerve damage and palsy, arthritis, tendonitis, chronic pain associated with plates, screws, and pins, compartment syndrome, deformity, audible popping and snapping, and possible future surgeries to remove the hardware.

Closed reduction 

Closed reduction internal fixation (CRIF) is reduction without any open surgery, followed by internal fixation. It appears to be an acceptable alternative in unstable distressed lateral condylar fractures of the humerus in children, but if fracture displacement after closed reduction exceeds 2 mm, open reduction and internal fixation is recommended.

Various techniques of minimally invasive surgery for internal fixation of bones have been reported. The treatment of fractures of the distal third of the tibia has evolved with the development of improved imaging and surgical techniques.

Internal fixation implants for intracapsular hip fractures in older adults

The latest evidence suggests that there may be little or no difference between screws and fixed angle plates as internal fixation implants for intracapsular hip fractures in older adults. The findings are based on low quality evidence that cannot firmly conclude major difference in hip function, quality of life, and additional surgery.

Auster Tugmaster. The Auster 6A Tugmaster was a British high-wing monoplane glider tug converted from surplus former military Auster AOP.6s.

Development
The Auster Tugmaster is a high-wing braced monoplane with a fixed tailwheel landing gear and powered by a de Havilland Gipsy Major engine. The Tugmasters had their engines modified to civilian standards as the Gipsy Major 10 and they were also fitted with larger tail surfaces. Because of the original radio fit had been removed the second passenger sat in a sideways-facing seat behind the pilot and not side-by-side although three aircraft were fitted with dual controls and side-by-side seating.

When the Auster AOP.9 was introduced into British Army service from 1959, Auster Aircraft bought 104 surviving and now surplus Auster AOP.6 and T.7s. Initially 29 airframes were modified for glider towing as the Auster 6A Tugmaster. Each individual aircraft was stripped as necessary and re-built with minimum cost in a maximum of 400 manhours, with a selling price of £995. Subsequently, about 50 were converted as three-seater touring aircraft for civilian use as the Auster 6B, later designated as the Beagle A.61 Terrier.

The first conversion, test registration G-25-9, flew on 5 July 1960 and was produced by Air Tows Ltd at Lasham and was fitted with an electrically-driven winch; five more were modified by Air Tows. Twenty one were converted by Auster at Rearsby with a conventional Auster-designed towing hook. Other conversions were carried out by a number of organisations including one by British European Airways employees at London Heathrow Airport for their own gliding club at Booker. Some surplus Royal Canadian Air Force Auster AOP.6 aircraft were also converted in Canada for glider towing.

Examples of the Tugmaster were exported to Finland, Norway and Sweden. Several Tugmasters remain in service with UK gliding clubs (2014).

Binfield Park Dam. Binfield Park Dam is a dam on the Tyhume River, near Alice, Eastern Cape, South Africa. It was established in  1986, and commissioned in 1987.

The villagers underused the Binfield Park Dam and vicinity areas located nearby – no fishing, aquaculture, irrigation or recreation. It is concluded that with the help from Government and institutions, the appropriate use of indigenous knowledge and the dam can benefit the communities and the environment regarding ecotourism or ecofeminitourism.

Slauerhoffbrug. The Slauerhoffbrug () is a fully automatic bascule bridge (aka tail bridge) in the city of Leeuwarden in the Netherlands. It is a road bridge that carries the Slauerhoffweg (named after J. Slauerhoff) over the Harlingervaart. It was completed in 2000. 

The bridge uses two arms to swing a 15×15m section of road in and out of place. The lift arms are oriented diagonally to the road. The bridge is painted in yellow and blue, representative of Leeuwarden's flag and seal. This movable bridge is also known as the  “Slauerhoffbrug ‘Flying’ Drawbridge” or Frog Bridge (Dutch: Kikkerbrug), the last because of its shape in the down position. One of the main designers is Emile Asari. A tail bridge can quickly and efficiently be raised and lowered from one pylon (instead of hinges). This allows water traffic to pass while only briefly blocking road traffic.

Constrained-layer damping. Constrained-layer damping is a mechanical engineering technique to suppress vibrations. Typically a viscoelastic or other damping material, is sandwiched between two sheets of stiff materials that lack sufficient damping by themselves. The result is that any vibration generated on either side of the constraining materials (the two stiffer materials on the sides) is suppressed by the viscoelastic material, by turning it into heat. The damping is associated with the shear deformation of the viscoelastic material.

Desktop and mobile Architecture for System Hardware. Desktop and mobile Architecture for System Hardware  (DASH) is a Distributed Management Task Force (DMTF) standard.

Description
In April 2007 the Desktop and Mobile Working Group (DMWG) of the DMTF started work on an implementation requirements specification (DSP0232).  Version, DASH 1.1, was published in December 2007 and became a DMTF standard in June 2009. Version, DASH 1.2, was published in December 2014 and became standard in June 2015.

In-service and out-of-service systems can be managed, with manageability aligned between the modes, independent of operating system state.  Both HTTP and HTTPS management ports are supported: TCP ports 623 and 664, respectively, for connections from remote management consoles to DASH out-of-band management access points (MAP).

The DMTF Common Information Model (CIM) schema defines the supported DASH management data and operations. There are 28 CIM profiles supported in the DASH 1.1 specification. 9 new profiles were added and 4 profiles were updated in DASH 1.2 specifications.

DASH uses the DMTF's Web Services for Management (WS-Management) protocol for communication of CIM objects and services.

The web services expose a common set of operations for system management:
 DISCOVER
 GET, PUT, CREATE and DELETE management resources, such as property values & settings
 ENUMERATE for tables and collections
 SUBSCRIBE to and DELETE events (indication delivery)
 EXECUTE for services (method invocation)

Management access point discovery
Discovery of access points is a two phase process:
 Phase 1: an RMCP Presence Ping request is sent (broadcast, multicast or unicast) and an RMCP Presence Pong response is received indicating support for WS-Management.
 Phase 2: a WS-Management "Identify" request is sent and response is received indicating support for DASH, which version, and which security profiles.

Protocols
DASH management protocols layers include:

Profiles
The DMTF CIM Profiles supported by the DASH 1.1 specification:

The DMTF CIM Profiles supported by the DASH 1.2 specification:

DASH is designed for desktop and mobile computer systems; a related DMTF standard for management of server computer systems is the Systems Management Architecture for Server Hardware (SMASH), with a similar set of CIM Profiles.

Intel Active Management Technology is a compliant implementation of DASH.
