Environmental Station Alpha. Environmental Station Alpha is a 2015 Metroidvania created by Finnish independent developer Arvi Teikari (known professionally as Hempuli).

Gameplay
The player character is a robot who must examine a vast bio-dome space station which was mysteriously abandoned, despite still holding signs of life.

The player explores the vast side-scrolling maze of the space station, consisting of several large areas. At the beginning of the game, many areas are inaccessible, so the player must acquire items that grant the robot new abilities (like a grappling hook, the ability to double jump, etc.), and then backtrack to previous areas to find previously-inaccessible paths leading deeper into the station.

Reception
Jed Whitaker of Destructoid scored the game 7/10 and said, "[o]verall, Environmental Station Alpha didn't reinvent the wheel when it comes to Metroidvania games, but it certainly helped satisfy my appetite." He praised the game's pixel art aesthetic and bosses, writing that "[t]hese confrontations are some of the most satisfying boss battles I've had in a game in some time"; however, he was less enthusiastic toward the game's mandatory backtracking to find new pathways, which he said could be either "rewarding, or tedious depending on the amount of time needed." John Walker of Rock Paper Shotgun also gave the game a positive review, calling it a "Metroid-alike pixel platformer that I’ve thoroughly enjoyed, right up until I didn’t any more. And yet, I find myself recommending it." He said that "[t]he fine balance of Metroid games is often underestimated by those wishing to emulate them, but Arvi Teikari and Roope Mäkinen demonstrate a rare skill of precision" but wrote that the game was too difficult for his tastes, labelling its later sections as "fiddly and over-complicated."

A speedrunning community has developed for Environmental Station Alpha, with the game having been run at the speedrunning marathons European Speedrunner Assembly and Games Done Quick multiple times apiece.

Crank machine. The crank machine was a penal labour device used in England in the 19th century. It consisted of a hand-turned crank which forced four large cups or ladles through sand inside a drum, doing nothing useful. 

The prisoner would typically be forced to do 6,000–14,400 revolutions over the period of six hours per day (1.5–3.6 seconds per revolution). The prison warden could make the task harder by tightening an adjusting screw.

In 1895, there were 29 crank machines in use, but by 1901 there were only 5.

Aventureiro Sustainable Development Reserve. The Aventureiro Sustainable Development Reserve (), formerly the Aventureiro Marine State Park, is a sustainable development reserve in the state of Rio de Janeiro, Brazil. It supports artisanal fishing by a small traditional community on the Ilha Grande, an island off the southwest coast of the state.

Location

The Aventureiro Sustainable Development Reserve (RDS) is in the municipality of Angra dos Reis, Rio de Janeiro.
It has an area of .
It covers a small part of the southwest of the Ilha Grande off the south coast of Rio de Janeiro near the border with São Paulo, and the bay in the southwest of the island. 
The RDS covers a small area of land, plus the bay, shore and rocks up to the high water mark.
The Praia do Sul Biological Reserve the remaining land around the bay.
62.5% of the island is covered by the Ilha Grande State Park, making a total of 87% of the island protected.

History

The Aventureiro Marine State Park was created by state decree 15.983 of 27 November 1990.
The purpose was to safeguard exceptional natural beauty, flora and fauna for use in education, recreational and scientific purposes.
It is part of the Bocaina Mosaic of conservation units.

A caiçaras community had lived in the area for over 150 years.
In recognition of their claims, on 28 May 2014 law 6793 authored by deputy Carlos Minc created the Aventureiro RDS from 2.7% of the Praia do Sul Biological Reserve, and the area covered by the Aventureiro Marine Park was incorporated into the RDS.
The RDS aims to preserve the ecosystems and also the traditional way of life of the caiçaras fishing community of about 50 families.
Only artisanal fishing is allowed, under the control of the Instituto Estadual do Ambiente (State Environmental Institute).
It was expected that creation of the RDS would help to protects the biological reserve.

Derivative code. Derivative code or Chameleon code is source code which has been derived entirely from one or more other machine readable file formats.  If recursive transcompiling is used in the development process, some code will survive all the way through the pipeline from beginning to end, and then back to the beginning again.

This code is, by definition, derivative code.  The following procedure can be used to easily test if any source code is derivative code or not.  
 Delete the code in question
 Build (or compile) the project
If the build process simply replaces the source code which has been deleted, it is (obviously) code which has been derived from something else and is therefore, by definition, derivative code.

If the build process fails, and a human needs to re-create the deleted code by hand, this is again, by definition, hand code.

The transcompilers and other tools which create derivative code, are usually themselves either in part, or entirely hand code.

Cryptographic splitting. Cryptographic splitting, also known as cryptographic bit splitting or cryptographic data splitting, is a technique for securing data over a computer network.  The technique involves encrypting data, splitting the encrypted data into smaller data units, distributing those smaller units to different storage locations, and then further encrypting the data at its new location.  With this process, the data is protected from security breaches, because even if an intruder is able to retrieve and decrypt one data unit, the information would be useless unless it can be combined with decrypted data units from the other locations.

History
The technology was filed for patent consideration in June 2003, and the patent was granted in June 2008.

Technology
Cryptographic splitting utilizes a combination of different algorithms to provide the data protection. A block of data is first encrypted using the AES-256 government encryption standard.  The encrypted bits are then split into different shares and then each share is hashed using the National Security Agency's SHA-256 algorithm.

Applications
One application of cryptographic splitting is to provide security for cloud computing.  The encrypted data subsets can be stored on different clouds, with the information required to restore the data being held on a private cloud for additional security. Security vendor Security First Corp uses this technology for its Secure Parser Extended (SPx) product line.

In 2009, technology services company Unisys gave a presentation about using cryptographic splitting with storage area networks.  By splitting the data into different parts of the storage area network, this technique provided data redundancy in addition to security.

Computer giant IBM has written about using the technology as part of its Cloud Data Encryption Services (ICDES).

The technology has also been written about in the context of more effectively using sensitive corporate information, by entrusting different individuals within a company (trustees) with different parts of the information.

Propylene chlorohydrin. Propylene chlorohydrin usually refers to the organic compound with the formula CH3CH(OH)CH2Cl. A related compound, an isomer, is CH3CH(Cl)CH2OH. Both isomers are colorless liquids that are soluble in organic solvents. They are classified as chlorohydrins. Both are generated on a large scale as intermediates in the production of propylene oxide.

The reaction of aqueous solution of chlorine with propene gives a 10:1 ratio of CH3CH(OH)CH2Cl and CH3CH(Cl)CH2OH. These compounds are treated with lime to give propylene oxide, which is useful in the production of plastics and other polymers.

Trippel SG6. The Trippel SG 6 was a Schwimmwagen (amphibious vehicle) developed in the 1930s and used by the German ground forces during the Second World War.

History

In 1935 Hans Trippel began to design all-terrain amphibious vehicle prototypes. In 1936 a factory was established in Hamburg for the mass-production of such vehicles.

Instead of a commercial suspension provided with a buoyant vehicle body, Trippel designed a streamlined, tub-shaped body into which the vehicle technology was fitted. The resulting Schwimmwagen SG 6 was intended for civilian use such as expeditions, but from the outset it was clear that the production of the vehicle could only be economical if military customers would order the amphibious vehicles in larger numbers. The first order of 20 vehicles went to the Wehrmacht. This version of the SG 6 was manufactured from 1937 to 1940.

At the end of September, 1938, a Trippel SG 6 was used on an advertising drive from Hamburg to Naples and then across the  water route to the island of Capri.

At the request of the military, a version of the SG 6 was built with an enlarged interior for transporting up to 16 soldiers. This military variant of Schwimmwagen was manufactured from 1939 to 1943.

In 1940, Trippel revised the streamlining and enhanced the detailing of the civilian version of the SG 6, resulting in the SG 6 Colonial Pioneer, but only a few were made because of the war.

Following the development of the swimming characteristics of the Colonial Pioneer model, the military version of the Schwimmwagen was also revised. The two doors were removed and the damage control improved. Production of this vehicle began in 1941 under the designation SG 6/41 at the Bugatti works in Molsheim in Alsace. With the outbreak of war in September 1939, Bugatti ceased the manufacture of expensive luxury vehicles and after the fall of France in June 1940, Bugatti, on August 12, 1940 signed a lease agreement with the Trippel-works, to move the latter's headquarters to Molsheim.

From 1942, a version of the SG 6 with a folding roof was manufactured. From 1943, the production of SG 6 was shut down, and in 1944 replaced by the Volkswagen Schwimmwagen Type 166 which was much lighter and also cheaper to manufacture. A total of about 800 SG-6-Schwimmwagen were produced.

Special Real Time Operating System. Special Real Time Operating System (SRTOS) is a discontinued IBM real time operating system, originally designed for use in the electricity industry, but later also applied in other areas of industrial process control. It formed part of the Realtime Plant Management System (RPMS) and Advanced Control System (ACS). Rather than a standalone operating system, it was designed as an extension to the OS/VS1 and OS/VS2 (later MVS) operating systems. It was also used in the paper industry. SRTOS was originally released in 1976, and though no longer supported as a program product, it is currently used as part of several ACS and RPMS installations worldwide.

Paper-ruling machine. A paper-ruling machine is a device for ruling paper. In 1770, John Tetlow was awarded a patent for a "machine for ruling paper for music and other purposes." William Orville Hickok invented an "improved ruling machine" in the mid-19th century. As the device is designed for drawing lines on paper, it can produce tables and ruled paper.

The functionality of the machine is based on pens manufactured especially for the device. The pens have multiple tips side by side, and water-based ink is led into them along threads. It is possible to program stop-lines on the equipment by mounting pens on shafts equipped with cams that lower and raise them at predetermined points.

The spread of computerized accounting between the 1960s and 1980s significantly decreased the demand for accounting tables and ruled paper. Nowadays, their demand is primarily filled by using offset printing.

Gateways (video game). Gateways is a 2012 action-adventure platform game created by British indie studio Smudged Cat Games. It is a mixture of gameplay concepts from the Portal and Metroid series.

Plot

The player character is Ed, a scientist who must take back control of his laboratory from a band of robotic monkeys.

Gameplay

Gateways is a side-scrolling game in which the player controls Ed as he makes his way through his maze-like laboratory. The player is equipped with a gateway gun that functions much like the portal gun in Portal, creating holes in walls, which the player can pass between. This mechanic is the basis of most of the game's puzzles. Throughout the adventure, the player will acquire additional gateway guns, featuring new abilities; by the end of the game, the player will be able to control time, gravity, and Ed's size.

Reception

Gateways received mixed reviews, currently sitting at 72/100 on Metacritic. Eurogamer scored the game 7/10, calling it a "stellar, well thought out puzzle gem on paper, and a tiny tragedy in practice." However, it also acknowledged that "[t]he esoteric nature of the game won't be to everyone's taste". PC Gamer awarded it 79/100, but criticized the navigation of the world, focusing specifically on "annoying bottlenecks [that] force you to solve the same fiddly problem with every pass", and also wrote negatively of "[t]he platforming itself ... [which] doesn't feel deftly defined." However, despite calling the game "[f]ugly and frustrating", the magazine concluded that Gateways was "a game of rare and rarely compromised ingenuity, and that alone makes its challenge worth accepting." Edge gave the game 8/10, praising it as "an unusually warm and charming entry in an occasionally clinical genre, [which] escapes from the shadow of its obvious inspiration with no small amount of ingenuity."

Alfred Hardy (architect). Alfred Hardy (1900–1965) was a Belgian contractor and autodidact architect. He became internationally known for his thin-shell concrete constructions in the 1950s and 1960s.

Biography 

Born in Quiévrain, he came into contact during World War II with the Ghent Professor Gustave Magnel and Brussels contractor Emile Blaton. Together with Polish engineer Simon Chaikes, he designed in 1947 two cylindrical aircraft hangars for the Grimbergen Airfield. This design was included in the Twentieth Century Engineering retrospective of 1964 in the New York Museum of Modern Art. His pioneering constructions contributed in architecture to the development of thin shells made out of reinforced concrete, later used by architects like Eero Saarinen or Félix Candela. The hangars are protected since 2007.

He designed his own house in 1954 in Buizingen, Belgium. He also designed an agricultural shed in Villepreux in 1953 that was designated by the government of France as a Monument historique in 2010.

Hardy married Emma Dassy and had two daughters (Nelly and Adrienne). He died in 1965 in road accident.

SAE 904L stainless steel. 904L is an austenitic stainless steel. It is softer than 316L,  and its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids; in particular, its copper addition gives it useful corrosion resistance to all concentrations of sulfuric acid. Its high alloying content also gives it greater resistance to chloride stress corrosion cracking, but it is still susceptible. Its low carbon content makes it resistant to sensitization by welding and prevents intergranular corrosion.

It has applications in piping systems, pollution control equipment, heat exchangers, and bleaching systems.

Omega SA experimented with 904L or 'Uranus Steel' with the PloProf dive watches in 1971–72. The inspiration came from French deep sea diving company COMEX, who used this steel in their diving bells due to superior corrosion resistance in salt water.
In 1985, Rolex began to utilize 904L grade steel in its watches.
Beside its corrosion resistance, watch manufacturers, such as Rolex, also choose this variety of stainless steel because it takes a higher polish than 316L grade stainless steel commonly used by other watch brands such as Seiko, Omega, and Tudor
