Desert Tech HTI. The Desert Tech Hard Target Interdiction (HTI) is a bullpup bolt-action sniper and anti-materiel rifle designed and manufactured in West Valley City, Utah, United States by Desert Tech (formerly Desert Tactical Arms).

Design
The Desert Tech HTI made its first public debut at Shot Show 2012 as a modular multi caliber bullpup Sniper Rifle.

The design of the HTI is largely based on the SRS-A1, scaled up to handle larger cartridges.  It is made out of high-impact polymers, aircraft grade aluminum (7075-T6), ultra high-strength steels, and durable coatings.  These materials make the firearm 12 pounds lighter, 12 inches shorter, and far more accurate than the comparable US M82A1 and M107 50 BMG rifles, in the same caliber, currently in service with various militaries around the world.

Barrels on the HTI can be changed within 60 seconds, allowing the chambering to be easily changed or worn out barrels to be quickly replaced. The chamberings currently available from Desert Tech are .375 Cheyenne Tactical (CheyTac), .408 CheyTac, .416 Barrett, and .50 BMG.

The bullpup design means the action is behind the trigger. As with all bullpups, this allows for a shorter overall length, without having to reduce barrel length.

Results of the shelf ammunition accuracy tests of the Desert Tech HTI firearm show between 0.549 MOA and 1.751 MOA, depending on ammunition used.

Mattel Hot Birds. Hot Birds is a set of 6 futuristic die-cast toy airplanes produced by American toy maker Mattel in 1971. All 6 of the models were manufactured in the US. 4 of the models were also produced in Hong Kong. Hot Birds were painted with the same Spectraflame paint as Mattel's Hot Wheels cars were painted. However, the planes came in only five colors, Red, Blue, Green, Gold/Yellow, and Magenta. Not all models came in all colors. These colors also came in varying shades believed due to the way the paint was mixed at the factory.

Model names/manufacturing countries were:
 6075 – Sky Scraper (USA and Hong Kong)
 6076 – Cloud Hopper (USA and Hong Kong)
 6077 – Star Grazer (USA and Hong Kong)
 6078 – Ski Gull (USA only)
 6079 – Maching Bird (USA and Hong Kong)
 6080 – Regal Eagle (USA only)

Rarity by Color

As Mattel does not publish production numbers these are only approximate. They are only to be used for collecting purposes.  For example, by using the chart one could conclude that Blue Ski Gulls are common while Green Regal Eagles are rare. 
The percentages don't reflect total models produced or country of origin.

William Keay. William Keay (1869-1952) was an English civil engineer and architect particularly associated with works in Leicestershire.

Career
Born in Leicester, Keay began his career as a civil engineer working with Everard, Son and Pick from 1911, while also developing his own partnership and extending into architecture (a member of the Institution of Civil Engineers, he was also eventually elected a fellow of Royal Institution of British Architects).

In 1923 his practice merged with the Pick Everard practice, which was joined by Martin Gimson in 1925 to become Pick, Everard, Keay and Gimson (since 1991 known as Pick Everard). Keay was also county architect for Leicestershire County Council with an office in the medieval Castle House in the Leicester Castle Close. In this role, his projects included:
extensions to Carlton Hayes Hospital (1930s)
the County Offices on the corner of Friar Lane and Greyfriars, Leicester (1936)
Hinckley police station (1937)
Hinckley cottage hospital extensions (1936-9)
St John's church, Coventry Road, Hinckley (1948)

Other works included:
overall planning and early buildings of the Leicester University College campus, including Wyggeston boys and girls grammar schools (from 1921)
Holy Apostles Church on Fosse Road South (1923-4)
assistance to Sir Charles Nicholson on work at Leicester Cathedral (1927)
St Christopher’s Church in Marriott Road, Leicester (1928 – now the Church Hall)
an extension to Ernest Gimson’s “Inglewood” in Ratcliffe Road, Leicester (1930)

During the 1930s, he made a detailed record and carried out archaeological excavations on the site of Ulverscroft Priory in Charnwood Forest.

He lived for a time in Glenfield at a house called "The Gynsills" (now a pub), formerly owned by the Ellis family associated with the Bardon Hill quarrying business, Ellis and Everard.

Penar branch line. The Penar branch line and the Hall's branch line, (also known as the Hall's Tramway and Hall's Road) was a standard gauge freight railway line running between Risca and the Oakdale Colliery in the South Wales coalfield. It finally closed when the colliery closed in 1989 but several sections of the trackbed, line and footbridges remain, around Crosskeys.

History

The line was originally built between 1808 and 1812 as a private tramway by Benjamin Hall, 1st Baron Llanover to connect mines he owned near Markham and Argoed in the Sirhowy Valley initially to Newbridge where it connected with the Crumlin Arm of the Monmouthshire and Brecon Canal, later probably extended to Risca.

At first the tramway was only 3 ft wide and used horses drawing small wagons for the nine mile journey.

in 1876, the line was acquired by the Great Western Railway on a thousand-year lease.

British Rail 

For official purposes two different Engineer's Line Reference (ELR) codes were allocated to the line by British Rail. The section from Halls Road Junction (at Lime Kiln Junction, Crosskeys) to Penar Junction was denoted HRD (for Halls Road branch); while the section from Penar Junction to Oakdale Colliery (Colliers Arms) was PEN (for Penar branch). The line west of Penar tunnel (= railway spelling) made a junction with the Vale of Neath line (VON) at Penar Junction. 

In December 1967, due to rationalisation of the railway network, the Halls Road branch was taken out of use for a period and the closed Vale of Neath line was brought back into use between Penar Junction and Bird-in-Hand West to join the former LMS Sirhowy line to Nine Mile Point via Tredegar Junction Lower and Wyllie. For that journey, a run around siding had to be established on the barren VON formation at Penar Junction for the locomotive to run around its train for forward journey to Oakdale or return journey to Newport. 

When the former LMS branch to the Sirhowy Valley from Nine Mile Point closed, the Halls Road section was reopened in May 1970 until closure of both the Halls Road and the Penar branches after 1989.

Compute kernel. In computing, a compute kernel is a routine compiled for high throughput accelerators (such as graphics processing units (GPUs), digital signal processors (DSPs) or field-programmable gate arrays (FPGAs)), separate from but used by a main program (typically running on a central processing unit). They are sometimes called compute shaders, sharing execution units with vertex shaders and pixel shaders on GPUs, but are not limited to execution on one class of device, or graphics APIs.

Description 

Compute kernels roughly correspond to inner loops when implementing algorithms in traditional languages (except there is no implied sequential operation), or to code passed to internal iterators.

They may be specified by a separate programming language such as "OpenCL C" (managed by the OpenCL API), as "compute shaders" written in a shading language (managed by a graphics API such as OpenGL), or embedded directly in application code written in a high level language, as in the case of C++AMP. Microsoft support this as DirectCompute.

Vector processing 

This programming paradigm maps well to vector processors: there is an assumption that each invocation of a kernel within a batch is independent, allowing for data parallel execution. However, atomic operations may sometimes be used for synchronization between elements (for interdependent work), in some scenarios. Individual invocations are given indices (in 1 or more dimensions) from which arbitrary addressing of buffer data may be performed (including scatter gather operations), so long as the non-overlapping assumption is respected.

Vulkan API 

The Vulkan API provides the intermediate SPIR-V representation to describe both Graphical Shaders, and Compute Kernels, in a language independent and machine independent manner. The intention is to facilitate language evolution and provide a more natural ability to leverage GPU compute capabilities, in line with hardware developments such as Unified Memory Architecture and Heterogeneous System Architecture.  This allows closer cooperation between a CPU and GPU.

Boot (software). Boot is a build automation and dependency management tool written primarily in the Clojure programming language.

Boot was originally written by Micha Niskin and Alan Dipert as part of the Hoplon web framework.  As of May 2015, Boot is developed and released independently of Hoplon.  Boot is implemented as an executable entry point and a set of Clojure libraries that can be used to develop build processes programmatically.  The spirit of Boot's design is captured by its tag line, "Builds are programs. Let's start treating them that way."

Build tasks supported natively by Boot include compiling Java, creating .jar files, and creating servlets.  As a Clojure program, Boot can be extended on a per-project basis using the Clojure language.  Boot's primary means of extension are tasks, or functions that take and return Filesets.  A Fileset is a managed, immutable representation of the filesystem and classpath that can be synchronized to disk at any point during the build.  Like Leiningen, Boot supports resolving and publishing Maven dependencies using the Aether library.

Boot also supports:
 In-process classloader isolation with pods
 Shebang scripts

Boot is featured in Appendix B of the book "Clojure for the Brave and True".
