HackNY. hackNY is a New York City-based initiative seeking "to create and empower a community of student-technologists." hackNY was created in 2010 by Evan Korth, Hilary Mason, and Chris Wiggins. The organization is organized by faculty at both New York University and Columbia University.  hackNY holds semiannual, 24-hour "hackathons", and runs a summer Fellows Program which pairs students in the computational sciences with local startup companies.

Each semester, hackNY holds a 24-hour coding marathon, or "hackathon", often at New York University's Courant Institute of Mathematical Sciences, but in Spring 2013 at Columbia's Engineering School.  The events are open to all students, not just of Columbia and NYU. The hackathons begin with brief presentations from startups that make their APIs available to the participants.  The students are encouraged, though not required, to work together to come up with creative solutions or build new features before the time runs out. The hackathons conclude with a presentation of the students' work, and judging.

hackNY organizes a summer program that pairs quantitative and computational students with startup companies. A list of startups that hosted students during previous years can be found here . The students are compensated, receive free housing, and attend a lecture series  showing them what it's like to join, or found, a  startup company.

All British Ford. The ABF or All British Ford was a car manufactured by Canadian born garage owner and inventor Albert (Bertie) Ford in Kenilworth, Warwickshire between 1918 and 1920. Engines used included a water-cooled two-stroke flat-twin and a four-stroke 4-cylinder V-pattern with shaft drive to the rear wheels via a 3-speed gearbox in unit with the engine.

Series production was intended but a combination of the early post-war slump in England, illness to Ford and competition from better-funded manufacturers meant that only prototypes were built.

Eggplant Software. Eggplant Software, Inc., was a software testing and monitoring company. Eggplant was a global company that served more than 650 enterprise customers in over 30 countries.

Eggplant had offices in London, Boulder, Colorado, Philadelphia, and Berlin, Germany, with additional development centers and regional offices around the world. Eggplant was acquired by Keysight Technologies.

Products
Eggplant's products cover: 
 Automated, AI-driven functional and usability testing
 Performance testing
 Robotic Process Automation (RPA)
 performance monitoring (real user and synthetic).

Many of these products work together. For example, real user journeys from monitoring can be used to build journeys for functional testing.

History
The Eggplant software test automation product was originally developed and sold beginning in 2002 by Redstone Software, a subsidiary of Gresham Computing. In 2008, the Eggplant software (and associated SenseTalk scripting language) was acquired by a group of investors who created a new company called TestPlant to continue the promotion and development of Eggplant. It was created to help organisations put users at the centre of software testing to create amazing digital experiences and drive user adoption, conversion, and retention.  After an initial round of seed funding ($100,000), the company was able to invest in developing technologies ─ predominantly the Digital Automation Intelligence (DAI) suite ─ which interacts with software exactly like a real user does. In 2018, the company rebranded as Eggplant to align with expansion and growth in the US market.

On 28 March 2018 Eggplant announced the acquisition of NCC Group's Web Performance Division.

On 25 June 2020, Eggplant was acquired by Keysight Technologies for $330 million from the Carlyle Group.

DDP-24. The DDP-24 (1963) was a 24-bit computer designed and built by the Computer Control Company, aka 3C, located in Framingham, Massachusetts. In 1966 the company was sold to Honeywell who continued the DDP line into the 1970s.

Hardware
The DDP-24 was completely transistorized and used magnetic-core memory to store data and program instructions. It had a sign magnitude code to represent positive or negative numbers and used binary logic. The DDP-24 used a single address command format and single operation with index and indirect addressing flags.

Market acceptance
The DDP-24 found use in space and flight simulators of the mid-1960s and other real-time scientific data processing applications.

Peter B. Denes, a researcher at Bell Telephone Laboratories, Inc., installed a DDP-224 system around 1965 for use in speech research. It and a DDP-24 were used by Max Mathews, considered by many to be the founding father of computer music, to develop his GROOVE music system, as related by Professor Barry Vercoe in a 1999 MIT Media Lab interview. When asked to describe the first MIT experimental music studio, Prof. Vercoe replied, "We began that work when I first arrived in 1971. The first studio we had was in the basement of Building 26, where we had a computer given to MIT by Max Mathews--the Honeywell DDP-24. Max initially developed his GROOVE system on this machine and was kind enough to give it to MIT when I joined the faculty." The 3C DDP-24 used modules or cards called S-Pac's. These S-Pac cards could be Flip-Flops, NAND gates, Bit Registers etc. and were housed in a DDP-24 S-Bloc card rack. An early raster-scan graphics display was developed for the computer system.

Arup Manufacturing Corporation. Arup Manufacturing Corporation  was an American aircraft manufacturer of tailless aircraft.

History 

Dr. C.L. Snyder experimented with tailless aircraft starting with a 1926 glider called the Dirigiplane. The aircraft used a Clark Y airfoil that could be filled with helium gas to assist with lift. Snyder formed the Monowing corporation to further develop the aircraft. The design progressed into the Arup S-1 design and the formation of Arup Manufacturing.

In 1934, Snyder's chief engineer, Raoul J. Hoffman left the company to create a similar design, the Hoffman Flying Wing. His breakaway project ended with the crash of the prototype from an onboard fire.

Hornby Track Master. Hornby Track Master is a software tool to design Hornby Railways train tracks.

Gameplay
Hornby Track-Master is a birds eye 2D Planning tool, distinct from Hornby Virtual Railway (HVR). HVR uses a 3D Planning Environment in which one can plan, build and test a layout. However, being released many years ago, it has fairly low quality graphics. 

Hornby Track-Master, on the other hand, also allows for the development of a shopping list for every thing needed to build a track, but it has no 3D whereas HVR does.

Users select pieces of track from lists and place them where they wish. Track-Master uses birds-eye view to work. Track, platforms, turntables etc. can be added. Once completed the software develops a printable shopping list.

Borsche–Drechsel cyclization. The Borsche–Drechsel cyclization is a chemical reaction used to synthesize tetrahydrocarbazoles by the acid-catalyzed cyclization of cyclohexanone arylhydrazones. The reaction was first described by  in 1888 and by  in 1908.

Borsche–Drechsel cyclization is the central step in Borsche–Drechsel carbazole synthesis, where in the first step phenylhydrazine is condensed with cyclohexanone to form the cyclohexanone phenylhydrazone, and in the final step the resulting tetrahydrocarbazole is oxidized to carbazole itself.

Mechanism 
The reaction has been described in the literature as proceeding in a manner similar to the Fischer indole synthesis.

Here, the acid-catalyzed proton transfer first converts the cyclohexanone phenylhydrazone 1 to the intermediate 2. Subsequently, a heat-induced sigmatropic reaction occurs to produce 3, which is protonated and cyclizes into 4. Elimination of ammonia then leads to the final product, the tetrahydrocarbazole 5.

Tulloch Limited. Tulloch Limited was an Australian engineering and railway rolling stock manufacturer, located at Rhodes, New South Wales.

History
In 1885, Robert Tulloch founded Phoenix Iron Works in Pyrmont. In 1913 the business was incorporated as Tulloch's Phoenix Iron Works and relocated to Rhodes. It primarily built freight wagons for the New South Wales Government Railways but also built single deck electric carriages for the Sydney suburban network from 1926 until the 1957. During World War II, a number of boats were built for the Royal Australian Navy including some 120ft Motor Lighters. In April 1948 the first of four seven-carriage HUB sets was delivered.

In the 1950s, it commenced building locomotives with 27 Victorian Railways W class diesel hydraulic shunters and 13 Commonwealth Railways NT class diesel locomotives delivered.

In 1964, Tulloch delivered the first double-decker trailer cars for use in Sydney. After the success of the trailers, Tulloch built four experimental double-decker power cars in 1968, each with electrical equipment from four different manufacturers: English Electric, Toshiba, Hitachi and Mitsubishi, the latter being selected as the supplier for the S class double decker power cars. These four motor cars were each paired with modified matching trailers from the original fleet of 120, and ran as an 8-car set with the target plate S10, giving NSW the first fully double deck Electric Multiple Unit passenger train in the world.

In the 1970s, the company built 10 New South Wales 1200 class railcars and 2 Victorian Railways DRC class railcars. In October 1974, Tullochs ceased trading. The Rhodes Corporate Park has been built on the former site.

In 1988, Skitube Alpine Railway acquired a diesel-mechanical locomotive built by Tulloch in 1958 for use as a depot shunter. This small locomotive was believed to have been the first to be built at the Tulloch plant at Rhodes.

Products
Vehicles manufactured by Tulloch Limited include:
203 Sydney single deck carriages
28 New South Wales HUB carriages
26 Victorian Railways W class (diesel-hydraulic) & 1 New South Wales 71 class locomotive
2-foot gauge diesel shunting locomotives
15 Western Australian Government Railways T class shunting locomotives

Kevin L.G. Parkin. Kevin L.G. Parkin (born 1977 in London) is an American British scientist who is best known for his study of beamed energy propulsion.

Areas of interest
Rocket propulsion and gasdynamics, high power microwaves and directed energy, object-oriented software engineering, space mission design. ince 2016, Kevin has served as the systems director of Breakthrough Starshot, a $100M initiative to send a beam-driven probe to Alpha Centauri within the next generation.

Education
Parkin attended the University of Leicester, where he received his bachelor's degree in physics in 1999. He then attended graduate school at the California Institute of Technology, where he received his master's degree in science in 2001. He completed his Ph.D. at Caltech in 2006, from which he derived his research for beam energy.

Career
Parkin was previously a member of the Carnegie Mellon Silicon Valley Research Staff and previously Deputy Director of the Mission Design Center at NASA Ames, and project lead for the Microwave Thermal Rocket. Beginning with his Ph.D. thesis on Microwave Thermal Propulsion, his work spans theoretical, computational and experimental domains for the general problem of space access and economics. In July 2005, he was awarded the Korolev Medal by the Russian Federation of Cosmonautics.

He founded the NASA Ames Mission Design Center (MDC) and developed its software architecture. The Ames MDC was the first of its kind to make extensive use of groupware, for example in pooling knowledge to create and maintain spacecraft parts databases. Another innovation was the use of a centralized parametric mission design archive that enables realtime concurrent design collaboration and object-oriented style 'inheritance' of missions to promote reuse of designs and the growth of design trees.

In 2010, Parkin was tapped by the NASA Ames Center Director to manage the 100 year Starship study for NASA and DARPA.

Parkin is a member of the Institute of Physics (IOP).

George Cornwell. George Cornwell ( – ) was a British railway engineer and building contractor working in Melbourne, Victoria, Australia in the second half of the nineteenth century. Among his prominent works, were the Hawthorn Railway Bridge built in 1861, with a span of about , being one of the last major items of permanent way to be completed on the fledgling Melbourne and Suburban Railway. Under the name 'George Cornwell and Co.' Cornwell had previously been involved as contractor in many other major construction works including the Melbourne Grammar School, the Model School, Coppin's Haymarket Theatre, the Sunbury railway goods shed and other Melbourne and Suburban Railway works. Subsequently, he was a contractor on Parliament House, Albert Park Station, Jack's Magazine and the Wallaby Creek water supply.

His work also extended to New South Wales, where he won the construction contract for the Wagga Wagga to Albury section of the Great Southern Railway on 14 February 1878, in partnership with F Mixner.

Family and connections
Cornwell married in 1850 Jemima Ridpath. The family was wealthy and well connected. His eldest daughter Alice Ann Cornwell was born in 1852 and she married and then left John Whiteman MLA. She became independently wealthy due to investing in mines. She went to England and bought The Sunday Times newspaper. His youngest daughter Kathleen Clarice Louise Cornwell (1872–1954) was a prolific writer first married to the music critic Herman Klein, and her daughter, Denise Robins, and her granddaughter, Patricia Robins, also became popular novelists.

Cornwell, however, was also prone to arguments and litigation. In 1883, McColl, a 65-year-old Member of the Victorian Legislative Assembly, took him to court for alleged assault but the action was unsuccessful.
