TI StarterWare. StarterWare was initially developed by TI as a free software package catering to their arm A8 and A9 microprocessors. Its primary purpose was to offer drivers and libraries with a consistent API tailored for processors within these microprocessor families. The package encompassed utilities and illustrative use cases across various applications. Despite TI's diminished active backing, the software lingers in open-source repositories on GitHub, primarily upholding support for widely used beagle boards that make use of these processors.

This software collection closely aligns with what many chip manufacturers refer to as a HAL (Hardware Abstraction Layer). In TI's context, it's termed DAL (Device Abstraction Layer). Its role revolves around furnishing fundamental functionalities and an API that an operating system can conveniently adapt to. For those inclined to create baremetal programs by directly engaging with the starterware API, the package also offered documentation and assistance.

Starck AS-80 Holiday. The Starck AS-80 Holiday is a conventional two-seat, single-engine high-wing monoplane designed and built in  France around 1950.  It was sold in kit form but only a few were completed.

Design and development
The Holiday is wood framed and fabric covered throughout.  Its high wing, built around two spars, has constant chord and rounded tips.  It is braced to the lower fuselage longerons with two V-form pairs of struts, assisted by jury struts.  The tail unit is braced, with the tailplane set at mid-fuselage height.  The fin is straight edged, the rudder generous, rounded and fitted with a trim tab.

The rectangular cross-section fuselage is deep behind the cabin, its upper surface at wing height.  The cabin is under the wing with the windscreen at the leading edge and its glazing extending rearwards beyond the trailing edge.  Access is via trapezoidal side doors.  The conventional fixed undercarriage has  mainwheels with low pressure tyes on faired V-struts and half axles hinged on an underside cabane.  The main unit is rubber sprung; the tail skid is spring steel. Some Holidays have had wheel fairings, others not.

The prototype Holiday first flew powered by a 56 kW (75 hp) Régnier 4D.2 four cylinder inverted inline air-cooled piston engine, but there was a wide range of suitable engines, both inline and flat fours, in the power range 44-63 kW (59-85 hp).  The second prototype, for example, had a 48 kW (65 hp) Continental A 65 flat four.  Though the inline Régnier engine was fully cowled, some of the flat fours have had exposed cylinder heads.

Operational history
At least seven Holidays have appeared on the French civil register. In 2010 four remained; one French-built Holiday is now (2012) on the UK register. Some of those currently registered may not be active.  Several of the Holidays first flew around 1950 but at least one was not completed until 1998. In France, the type was usually referred to as the AS.80 Lavadoux.

Massively parallel. Massively parallel is the term for using a large number of computer processors (or separate computers) to simultaneously perform a set of coordinated computations in parallel. GPUs are massively parallel architecture with tens of thousands of threads.

One approach is grid computing, where the processing power of many computers in distributed, diverse administrative domains is opportunistically used whenever a computer is available. An example is BOINC, a volunteer-based, opportunistic grid system, whereby the grid provides power only on a best effort basis.

Another approach is grouping many processors in close proximity to each other, as in a computer cluster. In such a centralized system the speed and flexibility of the interconnect becomes very important, and modern supercomputers have used various approaches ranging from enhanced InfiniBand systems to three-dimensional torus interconnects.

The term also applies to massively parallel processor arrays (MPPAs), a type of integrated circuit with an array of hundreds or thousands of central processing units (CPUs) and random-access memory (RAM) banks. These processors pass work to one another through a reconfigurable interconnect of channels. By harnessing many processors working in parallel, an MPPA chip can accomplish more demanding tasks than conventional chips. MPPAs are based on a software parallel programming model for developing high-performance embedded system applications.

Goodyear MPP was an early implementation of a massively parallel computer architecture. MPP architectures are the second most common supercomputer implementations after clusters, as of November 2013.

Data warehouse appliances such as Teradata, Netezza or Microsoft's PDW commonly implement an MPP architecture to handle the processing of very large amounts of data in parallel.

Starck AS-57. The Starck AS-57 is a single engine low wing monoplane seating two in side-by-side configuration.  It was designed and built in France just after World War II; only ten were produced, one of which was still active in 2012.

Design and development
Like the earlier Starck A.S. 70 Jac single seat light aircraft, the AS-57 was an all wooden machine. The two types were similar in layout, apart from the accommodation, though the AS-57 was larger all round. The wings were straight tapered in plan, with rounded tips. The earliest AS-57 had full span trailing edge control surfaces which could be lowered as flaps and operated differentially at the same time as ailerons, though one later specimen at least had ailerons outboard and separate flaps inboard. Leading edge slots are fitted. The side-by-side configuration seating is enclosed under a bubble canopy which has transparent access panels. At the rear the canopy line drops to the upper fuselage to improve the pilot's view aft. The fuselage tapers back to the tail unit, where the tailplane is mounted just above the upper fuselage surface, braced from below with a pair of struts and placed well forward of the straight leading edge of the fin. The fin has a curved top which merges into a full, rounded rudder.
 
The AS-57 has a fixed conventional undercarriage; some have had wheel fairings, others not. There is a small tailwheel.  Various engines have been fitted; the one remaining active aircraft has a 78 kW (105 hp) Walter Minor 4-III  but another had a Regnier 67 kW (90 hp) 4E.0, both four cylinder, inverted, air-cooled inlines.

The AS-57 flew for the first time on 4 April 1946.

Operational history
An AS-57 was on view at the 1949 Paris Salon. The general later verdict on the AS-57 was that its appearance was pleasing and its characteristics "honest", but its performance unexceptional.
 
In 2010 only one AS-57, powered by a Walter Minor engine, remained on the French civil aircraft register. Another AS-57 is at the Musée Régional de l'Air at Angers, viewable though not on public  display.
