GRPC. gRPC (acronym for gRPC Remote Procedure Calls) is a cross-platform high-performance remote procedure call (RPC) framework. gRPC was initially created by Google, but is open source and is used in many organizations. Use cases range from microservices to the "last mile" of computing (mobile, web, and Internet of Things). gRPC uses HTTP/2 for transport, Protocol Buffers as the interface description language, and provides features such as authentication, bidirectional streaming and flow control, blocking or nonblocking bindings, and cancellation and timeouts. It generates cross-platform client and server bindings for many languages. Most common usage scenarios include connecting services in a microservices style architecture, or connecting mobile device clients to backend services.

As of 2019, gRPC's use of HTTP/2 makes it impossible to implement a gRPC client in a browser, instead requiring a proxy.

History 
From about 2001, Google created a general-purpose RPC infrastructure called Stubby to connect the large number of microservices running within and across its data centers. In March 2015, Google decided to build the next version of Stubby and make it open source. The result was gRPC.

Authentication 
gRPC supports the usage of Transport Layer Security (TLS) and token-based authentication. Connection to Google services must use TLS. There are two types of credentials: channel credentials and call credentials.

For token-based authorization, gRPC provides Server Interceptor and a Client Interceptor.

Encoding 

gRPC uses Protocol Buffers to encode data. Protocol buffers provide a serialization format and an Interface Definition Language.

Testing 
Some of the software tools used for testing gRPC implementations include Postman, ezy, Insomnia, and Step CI.

Adoption 
Many organizations use gRPC, including Uber, Square, Netflix, IBM, CoreOS, Docker, CockroachDB, Arista Networks,  Cisco, Juniper Networks, Spotify, Zalando, Dropbox, and Google as the original developer.

The open source project u-bmc uses gRPC to replace Intelligent Platform Management Interface (IPMI). On 8 January 2019, Dropbox announced that the next version of "Courier", their RPC framework at the core of their service-oriented architecture (SOA), would be migrated to be based on gRPC, primarily because it aligned well with their existing custom RPC frameworks.

MainView. MainView, currently advertised as BMC MainView, is a systems management software produced by BMC Software. It was created in 1990 by Boole & Babbage and became part of BMC Software's services after they bought out Boole & Babbage in a stock swap.

History 
MainView was created in 1990 by Boole & Babbage as office automation software, designed specifically to work on IBM hardware. The product was designed so that companies would be able to automate their data management systems as well as being able to control what is automated within each enterprise. In 1993, it was updated to include support for parallel processors.

The system gained popularity with users being pleased with its real-time data however expressed dissatisfaction with its usage of counterfactual history to make decisions. In 1998, following BMC Software's purchase of Boole & Babbage, they announced that they would continue to operate MainView by directly integrating it with their IBM hardware products rather than continuing to sell it as specifically as a separate software product. BMC Software continued to upgrade MainView to be compatible with new technologies. In 2016, MainView was upgraded to be compatible with Java Environments.

Advertising 
In 1993, Boole & Babbage signed a deal with Paramount Pictures to license Star Trek for use in their advertising. The first way they used it was to advertise MainView. They produced a short advertising film titled "The Vision", which included Star Trek: The Next Generation Commander William Riker (played by Jonathan Frakes, with whom B&B also signed a spokesman's deal) using MainView on the bridge of the USS Enterprise to promote MainView. Boole & Babbage also used Frakes to promote MainView in person at the Computer Measurement Group conference as well as to announce that MainView would become available for singular desktop computers later in that year.

Hole Land. Hole Land is an arcade fixed shooter developed by the Spanish company Tecfri and released in Japan in 1984.

Gameplay

Player controls a multi-colored robot able to move to right and left, jump and shoot enemies such as small humanoids, rats, ghosts and snakes that come from holes above on the screen, vertically far away from the player, who stands always at the bottom of the stage and has to eliminate them all before they reach the bottom or simply avoid them to complete each level. Enemies are able to attack the player with bombs, making him unable to jump, move and shoot for a short time. The player can also become defenseless getting hit by incoming rocks from vulcans. A life is lost when enemies touch the player and take away the robot's lower half, which can be avoided by jumping over them without touching them.

The game has three stages. In the first two, each time the robot is damaged by rocks and bombs, a friendly, short, old man appears to help fix it.

At the last part of the third one, the player faces off the game's boss: a grotesque giant monster with a ball-shaped body and an enormous mouth with pointed teeth. The goal is to shoot and destroy all of its teeth before it can reaches the player's position, otherwise the monster will devour the robot. If the player manages to win the boss, he is returned to the first stage.

Practical Solutions. Practical Solutions is a new methodology by which public transportation systems manage, define, and deliver roadway projects in the United States. The idea seeks cost-effective solutions to meet community-defined outcomes.  Practical Solutions incorporates concepts from the field of energy utilities such as least-cost planning, practical design, context-sensitive solutions, smart transportation, performance-based outcomes, and value engineering into one methodology to achieve results at the lowest cost to the public. Current states that have embarked in transitioning their State Departments of Transportation to this methodology in some form include: Pennsylvania, Missouri, Oregon, Washington, Kentucky, Tennessee, Colorado, California, and Hawaii.

From PennDOT's work, "Smart Transportation" or Practical Solutions is centered on these principles:
 Cost-effectiveness
 Planning and designing within the context of the community
 Choosing projects with high rate of return
 Improving the local transportation system, as well as that of the state
 Recognizing there are many other outcomes beyond level of service (delay)
 Safety being the most important metric, but for all modes of transportation and not just vehicles
 Maintaining and improving existing investments first
 Building Complete Communities through transportation investments
 Partnerships with local governments on land use is key to success

Schempp-Hirth Ventus-3. The Schempp-Hirth Ventus-3 is a sailplane produced by Schempp-Hirth.  It replaces the highly successful Schempp-Hirth Ventus-2.

Design and development
It was announced at the AERO Friedrichshafen in April 2015 where a mock-up was suspended from the ceiling of the exhibition hall. The prototype flew on 29 January 2016 at Flugplatz Hahnweide at Kirchheim unter Teck in Germany. Production of the first seven turbo Ventus 3T started on 28 April 2016. These competed in the 2017 World Gliding Championships and the 2017 European Gliding Championships. In the latter competition, pilots with Ventus 3T took the first three places in the 18m Class. A Ventus 3T also took first place at the World Championships at Hosín in 2018.

Two sizes of fuselage are now available, Sport and Performance; the latter is larger. The Sport fuselage is available as a pure glider, or with a turbo sustaining engine, or a front-end electric sustaining (FES) engine. Currently the larger fuselage is only available for the self-launching 'M' and the turbo versions.

The first version of the Sport fuselage with the front electric sustainer engine, Ventus 3F, first flew December 2017. The first version with the Performance fuselage, Ventus 3M, also flew in December 2017.

Features include 'bug-wiper' garages recessed in the fuselage. There are three ballast tanks in each wing (total capacity 178 litres) and an optional 7.8 litre tank in the fin. The outer two tanks are filled from the wing-tip. 15m tips are available.

It has been designed to carry more ballast than the Ventus 2 and so its gross weight is 75 kg greater than its predecessor. Its maximum gross weight is now the same to the ASG-29.

Specifications (Ventus-3 Sport or Performance Edition with 18m wings)

Either the turbo engine or the FES engine adds 50 kg to the empty weight given above

South Prairie Const. Co. v. Local No. 627, International Union of Operating Engineers, AFL-CIO. South Prairie Construction Co. v. Local No 627, International Union of Operating Engineers, AFL-CIO, 425 U.S. 800 (1976), is a US labor law case, concerning the scope of labor rights in the United States.

Facts
The union, Local No 627 of the International Union of Operating Engineers claimed that the South Prairie Construction Co and Peter Kiewit Sons' Co were both a single employer, and that they were committing an unfair labor practice under the National Labor Relations Act 1935 §8(a)(5) by refusing to apply a collective agreement to them. The union was already the representative of the bargaining unit.

The Administrative law judge held that the firms were one employer. The National Labor Relations Board held that South Prairie Co and Kiewit Co were separate employers. The Court of Appeals, DC Circuit, decided the firms were a single employer, reversing the NLRB decision under Radio and Television Broadcast Technicians Local Union 1264 v. Broadcast Service [1965] USSC 51, 380 U.S. 255 (1965).

Judgment
The Supreme Court found that the DC Circuit had legitimately identified two corporations as a single employer given that they had a "very substantial qualitative degree of centralized control of labor", but that further determination of the relevant bargaining unit should have been remitted to the NLRB.
