GSL-class berthing pontoon. The GSL class of jetty berthing pontoons are a series of four non self-propelled yardcraft built by Goa Shipyard Limited for the Indian Navy.

The pontoons are catamarans with rectangular shaped twin flat-bottomed hulls. The twin hulls are connected by trusses of round pipes with a steel deck covering the transverse beams. Each hull is divided into eight watertight compartments. The pontoons have hydro-pneumatic fenders on both sides to facilitate high energy absorption and low reaction loads. Two vertical roller fenders are located at the forward and aft corners, on the side, for corner protection. They are intended for berthing vessels having displacement up to 40,000 tons on a jetty by serving as spacers between the jetty and the ship.

They were built as part of an order to also construct one Service Barge Pontoon and four gangways. The request for proposal was issued on 7 March 2011 and the contract was signed in June 2011. By February 2013 all four pontoons had been delivered. Two pontoons were stationed at Naval Dockyard, Mumbai and two at the Naval Base in Karwar.

Zip Zap. Zip Zap is an action game developed by Ian Weatherburn for Imagine Software and released for the ZX Spectrum in 1983.

Gameplay
The player controls a robot sent to an unexplored planet called Hallucinor with the job of investigating it ahead of human colonisation. When it arrives, however, it is attacked by aliens and must manoeuvre its way through the planet, avoiding or killing the aliens, gathering fuel cells to remain powered, and escaping through teleportals to move on to the next level. The robot's circuitry has been damaged, however, so it cannot stop moving and has only limited braking power.

Reception

While Home Computing Weekly said that the game had "professional packaging, amazing graphics, thoughtful facilities and [was] well priced" and Sinclair User said that it was an "excellent arcade-quality game," Crash noted that it was below Imagine's usual standards and Simon Lane, reviewing for Popular Computing Weekly, criticised the game's difficulty, saying that it was "consequently frustrating to play".

High Speed Railway Bridge over AP7, Llinars del Valles. The Llinars Bridge this bridge is the first steel structure in the high-speed railway (HSR) joining Barcelona and the French Border. The  Llinars HSR bridge comprises two parts: a  composite steel–concrete structure crossing Autopista AP-7, and a continuous prestressed concrete bridge crossing the Mogent River with a maximum span of .

After analyzing many possible color combinations for the Llinars bridge, the designers selected blue for the members above the deck level and gray for the bottom of the longitudinal beams. This combination was intended to make the structure appear more slender.

Description
The  Llinars bridge comprises two parts:
A  composite steel and concrete structure crossing AP-7 and a continuous structure made of prestressed concrete crossing the Mogent River with a maximum span of . The location of the piers was dictated by the highly skewed angle of the highway crossing and by the launching process used to erect the bridge. The final bridge features a composite steel and concrete deck suspended on structural steel tied members.

Construction
Construction of the Llinars bridge began in 2003.
An effort was made to develop an aesthetically pleasing solution that would be transparent and well suited to the site. To avoid interfering with the operation of Barcelona’s critically important tollway, incremental launching construction methods were used for the composite steel and concrete section. This section includes a deck that is a continuous structure with five spans.

The suspension members have a typical box girder cross section with an average depth of . The flange width, , does not vary along the girder. For aesthetic reasons, the members have a radius of curvature of , limiting the large structure’s vertical clearance over the highway and diminishing its visual obtrusiveness.
A complex steel structure with innovative aesthetics. This High-Speed Rail Bridge required a complex dynamic analysis. The launching method used for construction avoided any interference with the traffic below and to complete the structure on time and budget.

Tim Goss. Tim Goss (born 28 February 1963), is a British motor racing engineer, and Chief Technical Officer of the RB Formula One Team.

Career
Goss graduated from Imperial College London, where he also completed postgraduate studies specialising in ignition of turbocharged engines. Goss then joined Cosworth in 1986.

Goss joined McLaren in 1990, becoming the engineer in charge of engine installation design. He was then appointed assistant race engineer to Mika Häkkinen, and then became chief test team engineer. After working as head of vehicle dynamics, he then worked as chief powertrain engineer – a role in which he oversaw the introduction of the sport's first-ever seamless-shift gearbox in 2005.

In 2005 he was appointed Chief Engineer for the McLaren MP4-21 and led the engineering design team of the Adrian Newey designed 2006 car. After a few races it soon became clear that it was not as competitive as its predecessor, the MP4-20, despite an apparent improvement in reliability. McLaren did not win a race all season, for the first time since 1996.

Goss was appointed Director of Engineering in January 2011. In February 2013, after McLaren confirmed the departure of Paddy Lowe to Mercedes F1 effective for the 2014 season, Goss was appointed Technical Director. He held the position of technical director until 2018 when he was removed from that post and replaced by James Key.

On 18 January 2023, Goss was appointed the FIA Single-Seater Technical Director, replacing Nikolas Tombazis who became  Single-Seater Director.

In January 2024, Goss joined RB Formula One Team as Chief Technical Officer.

WHOIS++. The WHOIS++ protocol is a distributed directory system, originally designed to provide a "white pages" search mechanism to find humans, but which could actually be used for arbitrary information retrieval tasks.  It was developed in the early 1990s by BUNYIP Information Systems and is documented in the IETF.

WHOIS++ was devised as an extension to the pre-existing WHOIS system.  WHOIS was an early networked directory service, originally maintained by SRI International for the Defense Data Network.  The WHOIS protocol is still widely used to allow domain ownership records in the Internet to be easily queried.

WHOIS++ attempted to address some of the short comings in the original WHOIS protocol that had become apparent over the years.  It supported multiple languages and character sets to help with I18N issues, had a more advanced query syntax, and the ability to generate "forward knowledge" in the form of 'centroid' data structures that could be used to route queries from one server to another.  The protocol was designed to be backward compatible with the older WHOIS standard, so that WHOIS++ clients could still extract meaningful information from the already deployed WHOIS servers.

Whilst WHOIS++ as a white pages directory service never really took off compared to competitors such as X.500, it did gain a notable amount of use in the United Kingdom as the underlying search and retrieval protocol of a number of subject based gateways funded as part of the Jisc Electronic library programme.  This was achieved using software called ROADS that provided WHOIS++ base and index servers and CGI based web interfaces to WHOIS++ clients.  The use of centroids to provide forward knowledge and query routing allowed a subject gateway to not only provide resources to academic users from their own database but also point them at other JISC funded subject gateways that might have useful information.

The WHOIS++ protocol is now designated by the IETF as a historic protocol and is no longer deployed in new systems or developed.

Singer Featherweight. The Singer Featherweight is a model series of lockstitch domestic sewing machines produced by the Singer Manufacturing Company from 1933 to 1968, significant among sewing machines for their continuing popularity, active use by quilters and high collector's value.

Design

A typical early 20th century sewing machine, like the Singer 27, was designed to be mounted in a treadle or table, and though reduced-size models with hand cranks and wooden cases were introduced, their weight strains the meaning of the word 'portable.' The first sewing machine designed for portability, with a completely enclosed movement, was invented in 1928 by Raymond Plumley and Richard Hohmann, engineers for the Frederick Osann Company, who took advantage of then-recent advances in alloy technology to create a machine housed in a lightweight cast aluminum body. Osann subcontracted manufacture and assembly to the Standard Sewing Machine Company of Cleveland, Ohio, which marketed the machine under a number of brands, including Osann, Standard, and General Electric.

Both companies encountered financial difficulties as the Great Depression worsened; Osann was acquired by Standard, which was in turn acquired by the Singer Manufacturing Company. Singer continued production of the Sewhandy under the Standard brand through the early 30s while working on an improved design, which would be introduced as the Model 221 during the 1934 World's Fair. Like the Sewhandy, the 221 featured aluminum construction and small size, weighing only , as well as an improved self-fastening bobbin case which simplified the design of the machine's bobbin driver.

Production
It is estimated that Singer produced and sold some 3.0–3.5 million Featherweight machines during the model's lifetime. Production of the original Featherweight ended in 1961, but continued at Singer factories in Quebec and Scotland until 1969. Later British versions have numerous cost-saving components including a belt drive and a simpler front thread guide. An especially sought-after free arm version, Model 222K, was produced in Scotland from c.1953 to c.1961 exclusively for the non-US market.

Attachments

A number of attachments are available for the Featherweight, including the following feet:

 Foot hemmer – used for hemming, making hemmed and felled seams, and for sewing on lace while hemming
 Adjustable hemmer – to make hems from 3/16" to 15/16" wide
 Multi-slotted binder – to apply unfolded bias binding 15/16" in width and folded bias bindings in sizes 1–5 (1/4" – 1/2"), or to add piping
 Edge-stitcher – replaces the presser foot, used to accurately stitch at the very edge of the fabric
 Gatherer – used to slightly gather material
 Ruffler – to make and apply ruffles in one step, to pipe ruffles, or to pleat material

In popular culture
In the 1999 movie October Sky, Laura Dern's character Miss Riley has a Singer Featherweight visible on a table when visited by the boys at her home.
