Duncan Simpson. Duncan Menzies Soutar Simpson  (23 December 1927 - 5 December 2017) was a Scottish test pilot who played a key role in the development of the Hunter aircraft, the Harrier, and the Hawk advanced trainer flown by the RAF’s Red Arrows. He was the former chief test pilot of Hawker Siddeley in the 1970s. He flew the first production Harrier aircraft in December 1967, and the first two-seat Harrier in April 1969.

Early life
He was born in Edinburgh, and was educated at Merchiston Castle School there. His uncle was a test pilot for the Fairey Aviation Company.

Career

de Havilland
After leaving school in 1945 he worked for de Havilland in Hertfordshire.

Royal Air Force
In 1949 he joined the Royal Air Force with 6FTS and 226 OCU, and flew the Gloster Meteor VIII with 222 Squadron. In 1953 he joined the Day Fighter Development Unit at the Central Fighter Establishment.

Hawker Siddeley Aviation

He joined Hawker Siddeley in 1954. He first flew the Hawker Siddeley P.1127 in August 1962; he was the third pilot to fly the P.1127. On 27 December 1967, he was the first the fly the first production Harrier GR1 XV738. On 24 April 1969 he was the first to fly the two-seat Harrier XW174; six weeks later on 4 June 1969 in this aircraft, he was forced to eject at low level (100 ft), over Larkhill in Wiltshire, when the engine failed at 3,000 ft. On ejection from the aircraft he broke his neck; he needed a bone graft, and surgeons had to operate via his throat. He returned to flying nine months later, and received the Queen's Commendation for Valuable Service in the Air in the 1969 Birthday Honours. After this incident, all Hawker aircraft were fitted with canopy severance cord to shatter the canopy before ejection occurred.

He became deputy chief test pilot in 1969. He became chief test pilot in 1970. He was the first to fly the Hawk HS1182 prototype (XX154) at around 7pm on 21 August 1974, and reached 20,000 ft in a 53-minute flight. The Hawk entered service with the RAF in November 1976.

Personal life
He married in June 1958 and had two sons, and a daughter. They lived in Guildford, Surrey.

He received an award in 2011 from the Honourable Company of Air Pilots. He received the OBE in the 1973 Birthday Honours. He became a Fellow of the Society of Experimental Test Pilots. He died aged 89 in December 2017.

Sara Russell. Sara Samantha Russell (born 1966) is a professor of planetary sciences and leader of the Planetary Materials Group at the Natural History Museum, London. She is a Fellow of the Meteoritical Society and of the Royal Astronomical Society.

Early life and education 
Russell was captivated by the Moon landing as a child. She studied at the University of Cambridge, where she was introduced to microanalysis by Jim Long. She had started studying natural sciences, but heard that geologists host the best parties, so switched courses. She was inspired to complete a PhD degree in geology after attending a lecture by Colin Pillinger, and moved to the Open University. She won the Royal Astronomical Society Keith Runcorn Prize for the best British doctoral thesis in geophysics in 1993.

Career 
Russell completed postdoctoral research at the California Institute of Technology and Smithsonian Institution. She joined the Natural History Museum in 1998, where she studied protostars and planets. In 2000 she edited the collection Protostars and Planets IV. Russell is leader of the micrometeorite and meteorite collection at the Natural History Museum, London. She has been on three expeditions to Antarctica searching for meteorites. She has been awarded the Antarctica Service Medal. She was awarded a Leverhulme Trust grant in 2005. In 2006 she studied the meteorites in the early solar system and the protoplanetary disc.

On behalf of the Natural History Museum, Russell was part of the team which arranged the acquisition of the Ivuna meteorite in 2008. In 2009 she published the book Meteorite with Caroline Smith and Gretchen Benedix. She won the Geological Society of London Bigsby Medal in 2010. In 2011 Russell took part in an exhibition at the Royal Observatory, Greenwich. She is a science team member of OSIRIS-REx. She was the initial point of contact in the process by which the Tissint meteorite came to be acquired by the Natural History Museum in 2012. In 2014 she studied Moon rocks brought back by the Apollo Astronauts, finding that the lunar crust did not form from a common source.

Russell has studied the origin of water in the inner Solar System with Monica Grady. She published Chondrules in 2018, a book which considers the silicate grains that form in the protoplanetary disk. The eponymous asteroid 5497 Sararussell was named after her. Russell is an advocate for diversity in science.

Beltecno Corporation. Beltecno Corporation (株式会社ベルテクノ) is a Japanese company based in Naka-ku, Nagoya that manufactures stainless steel products. It also manufactures kitchen equipment, bathroom fixtures, housing facility equipment, construction equipment and dyeing machines. The company was founded in 1947.

The company is listed in the JASDAQ Securities Exchange.

History and timeline 
In 1947, Suzuki-Shoten was established for manufacturing dyeing machines. Ten years later in 1957 Suzuki Seisakusho Co. Ltd was established with the aim of manufacturing and selling dyeing machines.

Then in 1960 Tokai Sink Co. Ltd was set up for the purpose of manufacturing and selling housing equipment. And in 1966  Tokai Sink Sales Co. Ltd was incorporated for the purpose of selling housing equipment.

When Suzuki Seisakusho Co. Ltd. merged with Tokai Sinku Co. Ltd and Tokai Sink Sales Co. Ltd in 1990, it changed its company name to Beltecno Co. Ltd.

Nearly ten years later the Beltecno Headquarter, Nagoya branch and the Manufacturing Department were certified by the International Quality Management System ISO9001 in 1998/1999. The company also incorporated Beltecno Giken East Co., Ltd. for manufacturing Stainless-Steel Reservoir.

In 2004, the corporation was listed on the JASDAQ Securities Exchange. And in 2006, the IGC Corporation, a subsidiary of Wood One Co., Ltd., implemented TOB and acquired 96.2% of the shares. Become a consolidated subsidiary of Wood One. It was later de-listed from JASDAQ Securities Exchange in 2007. Before becoming a wholly owned subsidiary of IGC Co., Ltd. through share exchange on March 1 that same year.

On February 1, 2008, a domestic housing equipment business was incorporated into Bell Kitchen Co., Ltd. through the inauguration and Bell Kitchen International Inc. in the United States to Bell Kitchen Co., Ltd. On April 23, the IGC Corporation transferred the shares of the company and the company Bell Dyeing to BT Holding Co., Ltd. The Suzuki family now owns all shares. The capital relationship with Wood One disappeared. On July 1 they merged  with Bell Dyeing Co., Ltd.

In 2009, the company incorporated Beltecno India Private Limited. Neemrana plant was constructed in Rajasthan.

In July 2011, a merger absorbed the separate dyeing machine business to 'Belle Dyeing'.

Enterprise and Data Center Standard Form Factor. The Enterprise and Data Center Standard Form Factor (EDSFF), previously known as the Enterprise and Data Center SSD Form Factor, is a family of solid-state drive (SSD) form factors for use in data center servers.

Form factors
EDSFF was developed by the Small Form Factor Technology Affiliate technical work group, which is itself under the organizational stewardship of the Storage Networking Industry Association.

As a family of form factors, it defines specifications for the mechanical dimensions and electrical interfaces devices should have, to ensure compatibility between disparate hardware manufacturers. The standard is meant to replace the U.2 form factors for drives used in data centers. EDSFF provides a pure NVMe over PCIe interface. One common way to provide EDSFF connections on the motherboard is through MCIO connectors.

EDSFF SSDs come in four form factors: E1.L (Long) and E1.S (Short), which fit vertically in a 1u server, and  E3.L and E3.S, which fit vertically in a 2u server. E3.S is approximately the size of an 2.5 inch (U.2) drive.

Samsung's NGSFF (also known as M.3 or NF1) form factor competes with EDSFF.

RS-366. In telecommunications, RS-366, later known as EIA-366, defines a standard for serial communications between computers and an auto dialer, which is used to dial telephones. It was intended to be used to automate the operation of modems. The standard uses the same DB25 connectors and electrical signalling standards of the well-known RS-232 standard, which RS-366 was designed to support. The CCITT had a matching standard, V.25.

The earliest modems were used in the SAGE system that automated the collection of radar data, digitized it, and sent it over modems on leased lines to the SAGE computers. Modems were soon being used in business roles, notably in the SABRE that was patterned on the SAGE system. In these roles, the connections were always to the same remote machine, so there was no need to dial the phone, only connect and disconnect.

There were some business cases for automated dialling, but these tended to be mission specific. One common example was for a bank's central computer to call out to branches to retrieve transactions, thus centralizing the phone costs at the computer site rather than each branch. As these were highly customized applications, this lent itself to the development of a variety of incompatible systems. RS-366 was an effort to standardize the communications with these dialler systems.

RS-366, unlike RS-232, was a partially parallel communication system. Although most of the standard used RS-232 serial-like signalling, the digits of the phone number were sent as a 4-bit binary number in parallel on pins 14 through 17, with 14 being the least significant digit. So to send the digit 9, pins 14 (1) and 17 (8) would be put to the "mark" state, whereas the digit 6 would mark pins 15 and 16.

With each digit, the host system data terminal equipment (DTE, typically a computer) would raise pin 2 to indicate the digit was ready for the dialler to read. When the dialler completed the read, it would raise pin 5 to indicate it was ready for another. The "digit" 10 represented a wait-for-dialtone, while 11 indicated the end of the number. Once the entire dialling string had been read to the dialler, the DTE would start dialling by raising pin 4.

While the RS-366 standard process was progressing, the Hayes Smartmodem was introduced. This combined the modem and autodialler in a single box and communicated with both using a single RS-232 cable. This eliminated the cost and complexity of needing two ports and devices. The need for RS-366 disappeared, but the standards process continued for a time and at least some products were introduced based on it. The standard was obsolete by the time the Telecommunications Industry Association took over the EIA efforts, and it was never referred to as TIA-366.

Historic Aviation Memorial Museum. The Historic Aviation Memorial Museum is an aviation museum located at the Tyler Pounds Regional Airport in Tyler, Texas.

History

Background 

The Lone Star Wing of the Confederate Air Force was established in 1981 to restore a PBY-6A and build a hangar to house it. However, before the latter could happen, the aircraft was destroyed in accident in October 1984. As a result, on 25 January 1985 he established the Historic Aircraft Memorial Foundation and began raising money for a museum.

Establishment 
The museum reorganized in 1995 to focus on the construction of a museum. To that end, a three phase plan for  exhibit hall,  multipurpose hall and  hangar on the east side of the airport was announced.

Almost two years after construction was completed, the first phase, the Raiford L. Perry Exhibit Hall, opened on 9 June 2001. By that time, the organization had changed its name to the Historic Aviation Memorial Museum and construction had begun on phase two. The museum received its first airplane, an F-1E, on loan from the U.S. Navy in December 2001. It continued to grow, adding an F-111, F-105 and T-33 in 2004 – the latter two from the Pate Museum of Transportation. By July 2005, all three buildings had been completed and an F-4 had been acquired.

Move 
The museum signed a lease for the  first floor of the old terminal building on the north side of the airport in June 2006. It began renovating the building, which opened to the public on 5 July 2007.

The museum received an F9F and an F-101 in 2011.

Facilities 
A library is located at the museum.

The original museum, now used as a restoration hangar, has housed two MiG-17Fs that are part of FighterJets, Inc. since 2000.

7022 aluminium alloy. 7022 aluminium alloy is an alloy in the wrought aluminium-zinc family (7000 or 7xxx series). It is one of the more complex grades in the 7000 series, with at least 87.85% aluminium by weight.

Like most other highly alloyed alloys, 7022 is a high strength alloy, with yield strength of 370 MPa. Designed to be resistant to stress corrosion cracking, it has decent corrosion and oxidation resistance comparable to 7075 aluminium alloy but worse than 7039 aluminium alloy. Good machinability, thermal conductivity and dimensional stability make 7022 alloy a material of choice for plastic injection molds.

7022 alloy can be heat treated to increase tensile strength in expense of workability, with most common grade been T651.

Notes: Alternative names for 7022 alloy are A7022 and AA7022.

Chemical Composition
 Aluminium: 88.35 to 92.4%
 Zinc: 4.3 to 5.2%
 Magnesium: 2.6 to 3.7%
 Copper: 0.5 to 1.0%

Id Tech 7. id Tech 7 is a multiplatform proprietary game engine developed by id Software. As part of the id Tech series of game engines, it is the successor to id Tech 6. The software was first demonstrated at QuakeCon 2018 as part of the id Software announcement of Doom Eternal.

Indiana Jones and the Great Circle features a fork of id Tech 7 known as "Motor".

Technology
id Tech 7 features ten times the geometric detail of id Tech 6 and higher texture fidelity. Moreover the capabilities of the game engine allow it to have a new system called "Destructible Demons", in which enemies' bodies become progressively destroyed and deteriorate in combat as they suffer damage. On PC, id Tech 7 supports Vulkan rendering only. Ray tracing and DLSS were added in June 2021. According to engine developer Axel Gneiting, the engine doesn't have a "main thread"; everything is implemented as jobs.

Improvements in comparison to id Tech 6
 1 million fewer lines of code, due in part to the removal of the OpenGL render-engine
 Unified HDR lighting and shadowing
 Full HDR support on PS4, PS4 Pro, PS5, Xbox One S, Xbox One X, Xbox Series S, Xbox Series X, PC and Stadia
 Multi PBR material compositing, blending, and painting

Exercism. Exercism is an online, open-source, free coding platform that offers code practice and mentorship on 74 different programming languages.

History

Software developer Katrina Owen created Exercism while she was teaching programming at Jumpstart Labs. The platform was developed as an internal tool to solve the problem of her own students not receiving feedback on the coding problems they were practicing. Katrina put the site publicly online and found that people were sharing it with their friends, practicing together and giving each other feedback. Within 12 months, the site had organically grown to see over 6,000 users had submitted code or feedback, and hundreds of volunteers contribute to the languages or tooling on the platform.

In 2016, Jeremy Walker joined as co-founder and CEO. In July 2018, the site was relaunched with a new design and centered around a formal mentoring mode, at which point Katrina stepped back from day-to-day involvement.

Product

In the past, the website differed from other coding platforms by requiring students to download exercises through a command line client, solve the code on their own computers then submit the solution for feedback, at which point they can also view other's solutions to the same problem. Since its second relaunch in 2021, solutions can be edited and submitted through a web editor, though the command line client remains available.

Exercism has tracks for 74 programming languages. Among the notable languages taught: ABAP, C, C#, C++, CoffeeScript, Delphi, Elm, Erlang, F#, Go, Java, JavaScript, Julia, Kotlin, Objective-C, PHP, Python, Raku, Red, Ruby, Rust, Scala, Swift, and V (Vlang).

In 2023, the site launched a "12 in 23" challenge for users to learn the basics of 12 different languages - one per month in 2023.

Open source

The Exercism codebase is open source.

In April 2016, it consisted of 50 repositories including website code, API code, command-line code and, most of all, over 40 stand-alone repositories for different language tracks. 

 Exercism has 14,344 contributors, maintains 366 repositories, and 19,603 mentors.
