null | closed_qa | Given this text, what is the third wealthiest state in the USA? | Hawaii became a unified, internationally recognized kingdom in 1810, remaining independent until American and European businessmen overthrew the monarchy in 1893; this led to annexation by the U.S. in 1898. As a strategically valuable U.S. territory, Hawaii was attacked by Japan on December 7, 1941, which brought it global and historical significance, and contributed to America's decisive entry into World War II. Hawaii is the most recent state to join the union, on August 21, 1959. In 1993, the U.S. government formally apologized for its role in the overthrow of Hawaii's government, which spurred the Hawaiian sovereignty movement.
Historically dominated by a plantation economy, Hawaii remains a major agricultural exporter due to its fertile soil and uniquely tropical climate in the U.S. Its economy has gradually diversified since the mid-20th century, with tourism and military defense becoming the two largest sectors. The state attracts tourists, surfers, and scientists with its diverse natural scenery, warm tropical climate, abundance of public beaches, oceanic surroundings, active volcanoes, and clear skies on the Big Island. Hawaii hosts the U.S. Pacific Fleet, the world's largest naval command, as well as 75,000 employees of the Defense Department.
Its relative isolation results in one of the highest costs of living in the United States, and Hawaii is the third-wealthiest state. | According to this text, Hawaii is the third wealthiest state in the United States of America. | null | null | null | 4102 |
null | general_qa | What is the difference between earphones and headphones? | Both earphones and headphones allow users to listen to audio from an input device. Their primary difference is in their form factor. Earphones tend to go inside your ears, while headphones sit on your ears (on your head).
Earphones are usually smaller and more portable, while headphones tend to have better sound quality and battery life, as they are larger and can fit more parts and larger batteries inside. Depending on your needs, either would be a good choice for listening to audio. | null | null | null | 4103 |

null | classification | What is the difference between a coastal cruising and blue water sailboat? | The designs, accommodations and compromises for these boats can be very different and reflect the likely sea conditions these boats would encounter, expected time at sea and different experiences of passenger comfort. The primary difference between these boats begins with the shape of the hull since many other design choices tend to be dictated by hull shape.
Coastal cruisers, which are generally sailed near shore and in safer weather conditions,
tend to have a flatter hull shapes since these boats, which means they tend to "slap" the water when coming off a wave. With a flatter hull shape, boat architects can make greater use of the cabin space and so coastal cruisers will generally have a more spacious interior. The helm (or the outdoor area from which the boat is navigated) is generally less protected and generally speaking, offers greater comfort and ease of moving around. Safety, protection and expected time away from marinas mean these boats can refill fresh water, recharge batteries, empty waste tanks more frequently and therefore, tend to have lower capacities.
Blue water boats, because they are intended to sail in open waters (hence the moniker "blue water") in more unpredictable weather, generally have tapered (or tear drop shaped) hull shapes with heavier keels (generally, lead) and deeper drafts. With these designs, blue water boats can withstand heavier seas and will "cut through" waves rather than "slap." Generally speaking, blue water boats offer a much more comfortable experience in rougher seas and will have bigger fresh water and fuel tanks and will likely feature generators and other equipment that allows these boats to away for longer periods.
Blue water boats feature tapered hulls so the beam or width of the boat narrows the closer it gets to the water line (and below), leaving less room in the interior cabin than an equally sized coastal cruiser. Foot for foot, blue water boats will feature fewer berths and will have more cramped quarters because of the narrowing beam.
Because blue water boats are intended to sail longer distances and will carry more fuel and fresh water, these boats interior space is further restricted to accomadate these practical requirements.
The differences in comfort, stability and likelihood of capsizing are all captured in mathematical calculations that can provide an abstracted comparison between these boat types so prospective buyers can anticipate the the experiences and trade offs each hull type would provide. | null | null | null | 4107 |

null | closed_qa | Given this paragraph about the Roman temple known as the Pantheon, tell me whether we definitively know why the temple was called the Pantheon. | The name "Pantheon" is from the Ancient Greek "Pantheion" meaning "of, relating to, or common to all the gods". Cassius Dio, a Roman senator who wrote in Greek, speculated that the name comes either from the statues of many gods placed around this building, or from the resemblance of the dome to the heavens. His uncertainty strongly suggests that "Pantheon" (or Pantheum) was merely a nickname, not the formal name of the building. In fact, the concept of a pantheon dedicated to all the gods is questionable. The only definite pantheon recorded earlier than Agrippa's was at Antioch in Syria, though it is only mentioned by a sixth-century source. Ziegler tried to collect evidence of pantheons, but his list consists of simple dedications "to all the gods" or "to the Twelve Gods", which are not necessarily true pantheons in the sense of a temple housing a cult that literally worships all the gods. | We do not know why the temple was called the Pantheon. Even Cassius Dio, a Roman senator who would have had more context by nature of living and ruling in Roman society, was only able to speculate where the name came from. | null | null | null | 4108 |
null | general_qa | How to find the area of a rectangle? | A rectangle is a closed two dimensional quadrilateral structure with four right angles (90 degrees). Opposite sides of a rectangle are parallel and of equal length. Usually, the length of longer sides is called length of a rectangle and the length of shorter sides is called width/breadth of a rectangle.
Area of the rectangle is calculated by multiplying the length and width of the rectangle. For example, If the length of the rectangle is l and the width of the rectangle is w then area of the rectangle = (l x w).
If all sides of a rectangle are of equal length then it is called a square. Thus, square is a special case of a rectangle. | null | null | null | 4109 |

null | closed_qa | What is Venture Capital? | Venture capital (commonly abbreviated as VC) is a form of private equity financing that is provided by venture capital firms or funds to startups, early-stage, and emerging companies that have been deemed to have high growth potential or which have demonstrated high growth (in terms of number of employees, annual revenue, scale of operations, etc). Venture capital firms or funds invest in these early-stage companies in exchange for equity, or an ownership stake. Venture capitalists take on the risk of financing risky start-ups in the hopes that some of the companies they support will become successful. Because startups face high uncertainty, VC investments have high rates of failure. The start-ups are usually based on an innovative technology or business model and they are usually from high technology industries, such as information technology (IT), clean technology or biotechnology. | Venture capital firms invest in early-stage companies in exchange for equity. | null | null | null | 4114 |

null | general_qa | Is plastic bad for us? | Have you ever thought about where your plastic water bottles go? It probably ends up in a landfill, where it will decompose for over 1000 years as it deposits toxic chemicals. Plastic is an invention that has done more harm than good. There are about 363,762,732,605 pounds of plastic covering the earth. Most of this plastic can’t be recycled. Although people think it is too expensive or inconvenient to get rid of plastics, we should reduce the amount of plastic used or increase the price of plastics. One reason is that when plastic invades a balanced ecosystem, it corrupts it completely. The marine biome is one that is affected by this product. The animals in the ocean die of suffocation, ingestion of plastics, and entanglement. The animals affected are seagulls, whales, seals, fish, and turtles, and that's just a few. The animals eat so much plastic that they die of constipation from it. Another reason is the presence of microplastics in food and people. About 99% of fish have microplastics in their stomachs, livers, and filets (the meat of fish). Approximately 80% of cows have microplastics in their meat and milk. A good point is that mealworms and waxworms are studied to digest plastics, and they should be added to landfills to break down plastics. There are about 50,000 particles of plastic in an adult person, and this number is rising fast. Third, most plastic is littered. There are about 10 million tons of plastic litter every year. Every week, you ingest about a credit card's worth of plastic. There are about 44 million pounds of plastic that are produced that is very deadly to the environment."The plastic in the environment is in your water, food, and body. These plastics should not be there; they can lead to cancer, according to a recent study. We need to stop using plastic in our lives. Some ways we can reduce the amount of plastic on earth are by using sustainable materials such as wood, plant fibers, and mushroom styrofoam. We can also try to buy recyclable plastics that have a triangle formed by three cycling arrows. Use a tote bag instead of a plastic one, or a metal and glass straw instead of a plastic one. You can also use a metal cutlery kit instead of plastic. These are all ways you can make a difference in your everyday life. | null | null | null | 4132 |

null | creative_writing | How many angels can dance on the head of a pin? | This exact question puzzled theologians for many hundreds of years, and led to many differing points of view. The issue with the question is that there is no correct answer- firstly, are angels real? If they are, how big are they? are they even able to dance? if they could dance, how much space would they need? Secondly, how big is the pin? is the pin a normal sized Earthly pin? or something much larger, on a celestial scale?
The answer relates to faith- if you believe in angels, you believe in their ability to dance, and believe in their specific ability to dance upon a pin, and can have an argument in any direction based on your faith that they underlying premise of the question could be a likelihood. If you do not have that faith, then your outlook would likely view this question with a great degree of cynicism, and you would probably view it as a pointless question.

null | closed_qa | Based on the given text, do beavers eat wood or do they only chop down trees for dams? | Beavers (genus Castor) are large, semiaquatic rodents of the Northern Hemisphere. There are two existing species: the North American beaver (Castor canadensis) and the Eurasian beaver (C. fiber). Beavers are the second-largest living rodents, after capybaras, weighing up to 50 kg (110 lb). They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet, and tails that are flat and scaly. The two species differ in skull and tail shape and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges.
Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams restrict water flow, and lodges serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ecosystem, beavers are considered a keystone species. | Beavers are herbivorous and are known to consume tree bark as part of their diet.

null | general_qa | How do you play blackjack? | Blackjack is a card game, among players and a dealer. Each player is initially given two cards and the dealer shows one card. Each player takes a turn deciding to request one new card, "double down" by taking one extra card and doubling their bet amount, or "splitting" if the player's two cards are identical by doubling their bet and subsequently splitting the two cards into two new games. Cards with kings, queens, or jacks count are considered to have.a value of 10. Cards with an ace can be considered to be either a 1 or 11, whichever benefits the player. The player has the choice to take one additional card at a time to increase their value, until their choose to stop and "stay", or lose the game if their cards total more than 21. Once the player chooses to "stay", the dealer goes through a similar process by taking new cards until they either go over 21 and lose, or reach 17, 18, 19, 20, or 21. The player wins if the sum of the value of their cards is greater than the sum of the value of the dealer's card. The the players sum of the value equals the dealers sum their value, then the game is a "draw" and a tie. A "blackjack" is when a player's first two cards total 21, and the player typically receives 150% the value of their bet. If both the player and the dealer have a blackjack on their first two cards, then it is considered a tie. | null | null | null | 4156 |

null | open_qa | How is it that some high net-worth individuals are able to avoid paying taxes completely? | The Internal Revenue Service (IRS) taxes regular income and investment income differently. For one type of common investment income i.e long term capital gains, the tax rates are 0%, 15% and 20% based on the annual income of the individual. The income used for calculating the above rates doesn't include income from the long term capital gains itself. For example, if an individual makes less than $41,675 for the year 2022 through regular income, his or her capital gains tax rate would be 0% even if the long term capital gains itself is more than a million dollars. Assuming many of these high net-worth individuals don't have any regular income and all their income is through long term capital gains, they end up paying no taxes at all. | null | null | null | 4157 |

The team must also learn how to communicate, build trust, and play together unselfishly. Putting too many players who are alphas and are good at the same things is much worse than having a team with less talent who plays as a unit and complement each other. | null | null | null | 4160 |

null | information_extraction | What are some of the uses of gilding metal? | Gilding metal is a form of brass (an alloy of copper and zinc) with a much higher copper content than zinc content. Exact figures range from 95% copper and 5% zinc to “8 parts copper to 1 of zinc” (11% zinc) in British Army Dress Regulations.
Gilding metal is used for various purposes, including the jackets of bullets, driving bands on some artillery shells, as well as enameled badges and other jewellery. The sheet is widely used for craft metalworking by hammer working. It is also used particularly as a lower-cost training material for silversmiths. Starting in 1944, shell casings made of gilding metal were melted down by the United States Mint to be made into pennies. These pennies replaced the less popular steel cent of 1943, and the pennies of this composition were produced until 1946.
Gilding metal was also used for the "bronze" Olympic medal at the 2020 Summer Olympics held in Tokyo, Japan in 2021.
Gilding metal may be annealed by heating to between 800–1,450 °F (427–788 °C). It should be cooled slowly afterwards, to reduce risk of cracking. | Army Dress, weapons, metalworking, penny production, and Olympic medals | null | null | null | 4165 |

null | general_qa | I've heard astronauts talk about the normalization of deviance and the risks therein. What is the normalization of deviance, and how do I avoid it? | The normalization of deviance was a term coined by the sociologist Diane Vaughan who participated in the review of the Challenger disaster. It was later the the subject of a number of public talks by astronaut Mike Mullane. The theory is essentially that when we accept deviations from an expected standard, the deviation becomes the standard. In the Challenger disaster, engineers kept noticing rubber o-rings that came back from tests in an out of tolerance state. Because there were no dramatic failures during the tests, the engineers adjusted the standard for the o-rings to absorb these abnormalities. Unfortunately, by normalizing deviance from the expected standard, it led to an o-ring failing during the Challenger launch, and the Challenger shuttle disintegrated in flight. The normalization of deviance is an important pitfall to avoid when running any organization, but especially those which put its members in high risk situations, such as space travel. To avoid it, you must remember, or learn, how and why certain standards were developed and adhere to them, even when pressures are high. | null | null | null | 4171 |

null | summarization | From the example given in this paragraph, what is an eigenvector? | The Mona Lisa example pictured here provides a simple illustration. Each point on the painting can be represented as a vector pointing from the center of the painting to that point. The linear transformation in this example is called a shear mapping. Points in the top half are moved to the right, and points in the bottom half are moved to the left, proportional to how far they are from the horizontal axis that goes through the middle of the painting. The vectors pointing to each point in the original image are therefore tilted right or left, and made longer or shorter by the transformation. Points along the horizontal axis do not move at all when this transformation is applied. Therefore, any vector that points directly to the right or left with no vertical component is an eigenvector of this transformation, because the mapping does not change its direction.

Model of the software development life cycle, highlighting the maintenance phase
In systems engineering, information systems and software engineering, the systems development life cycle (SDLC), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. The SDLC concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both. There are usually six stages in this cycle: requirement analysis, design, development and testing, implementation, documentation, and evaluation.
Overview
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems. Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates. Computer systems are complex and often link components with varying origins. Various SDLC methodologies have been created, such as waterfall, spiral, agile, rapid prototyping, incremental, and synchronize and stabilize.
SDLC methodologies fit within a flexibility spectrum ranging from agile to iterative to sequential. Agile methodologies, such as XP and Scrum, focus on lightweight processes that allow for rapid changes. Iterative methodologies, such as Rational Unified Process and dynamic systems development method, focus on stabilizing project scope and iteratively expanding or improving products. Sequential or big-design-up-front (BDUF) models, such as waterfall, focus on complete and correct planning to guide larger projects and limit risks to successful and predictable results.[citation needed] Anamorphic development is guided by project scope and adaptive iterations.
In project management a project can include both a project life cycle (PLC) and an SDLC, during which somewhat different activities occur. According to Taylor (2004), "the project life cycle encompasses all the activities of the project, while the systems development life cycle focuses on realizing the product requirements".
SDLC is not a methodology per se, but rather a description of the phases that a methodology should address. The list of phases is not definitive, but typically includes planning, analysis, design, build, test, implement, and maintenance/support. In the Scrum framework, for example, one could say a single user story goes through all the phases of the SDLC within a two-week sprint. By contrast the waterfall methodology, where every business requirement[citation needed] is translated into feature/functional descriptions which are then all implemented typically over a period of months or longer.[citation needed]
History
According to Elliott & Strachan & Radford (2004), SDLC "originated in the 1960s, to develop large scale functional business systems in an age of large scale business conglomerates. Information systems activities revolved around heavy data processing and number crunching routines".
The structured systems analysis and design method (SSADM) was produced for the UK government Office of Government Commerce in the 1980s. Ever since, according to Elliott (2004), "the traditional life cycle approaches to systems development have been increasingly replaced with alternative approaches and frameworks, which attempted to overcome some of the inherent deficiencies of the traditional SDLC".
Models
A ten-phase version of the systems development life cycle
SDLC provides a set of phases/steps/activities for system designers and developers to follow. Each phase builds on the results of the previous one. Not every project requires that the phases be sequential. For smaller, simpler projects, phases may be combined/overlap.
Waterfall
The oldest and best known is the waterfall model, which uses a linear sequence of steps. Waterfall has different varieties. One variety is as follows:
Preliminary analysis
Conduct with a preliminary analysis, consider alternative solutions, estimate costs and benefits, and submit a preliminary plan with recommendations.
Conduct preliminary analysis: Identify the organization's objectives and define the nature and scope of the project. Ensure that the project fits with the objectives.
Consider alternative solutions: Alternatives may come from interviewing employees, clients, suppliers, and consultants, as well as competitive analysis.
Cost-benefit analysis: Analyze the costs and benefits of the project.
Systems analysis, requirements definition
Decompose project goals[clarification needed] into defined functions and operations. This involves gathering and interpreting facts, diagnosing problems, and recommending changes. Analyze end-user information needs and resolve inconsistencies and incompleteness:
Collect facts: Obtain end-user requirements by document review, client interviews, observation, and questionnaires.
Scrutinize existing system(s): Identify pros and cons.
Analyze the proposed system: Find solutions to issues and prepare specifications, incorporating appropriate user proposals.
Systems design
At this step, desired features and operations are detailed, including screen layouts, business rules, process diagrams, pseudocode, and other deliverables.
Development
Write the code.
Integration and testing
Assemble the modules in a testing environment. Check for errors, bugs, and interoperability.
Acceptance, installation, deployment
Put the system into production. This may involve training users, deploying hardware, and loading information from the prior system.
Maintenance
Monitor the system to assess its ongoing fitness. Make modest changes and fixes as needed.
Evaluation
The system and the process are reviewed. Relevant questions include whether the newly implemented system meets requirements and achieves project goals, whether the system is usable, reliable/available, properly scaled and fault-tolerant. Process checks include review of timelines and expenses, as well as user acceptance.
Disposal
At end of life, plans are developed for discontinuing the system and transitioning to its replacement. Related information and infrastructure must be repurposed, archived, discarded, or destroyed, while appropriately protecting security.
In the following diagram, these stages of the are divided into ten steps, from definition to creation and modification of IT work products:
Systems analysis and design
Systems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem. SAD can help balance competing high-level requirements. SAD interacts with distributed enterprise architecture, enterprise I.T. Architecture, and business architecture, and relies heavily on concepts such as partitioning, interfaces, personae and roles, and deployment/operational modeling to arrive at a high-level system description. This high-level description is then broken down into the components and modules which can be analyzed, designed, and constructed separately and integrated to accomplish the business goal. SDLC and SAD are cornerstones of full life cycle product and system planning.
Object-oriented analysis and design
Object-oriented analysis and design (OOAD) is the process of analyzing a problem domain to develop a conceptual model that can then be used to guide development. During the analysis phase, a programmer develops written requirements and a formal vision document via interviews with stakeholders.
The conceptual model that results from OOAD typically consists of use cases, and class and interaction diagrams. It may also include a user interface mock-up.
An output artifact does not need to be completely defined to serve as input of object-oriented design; analysis and design may occur in parallel. In practice the results of one activity can feed the other in an iterative process.
Some typical input artifacts for OOAD:
Conceptual model: A conceptual model is the result of object-oriented analysis. It captures concepts in the problem domain. The conceptual model is explicitly independent of implementation details.
Use cases: A use case is a description of sequences of events that, taken together, complete a required task. Each use case provides scenarios that convey how the system should interact with actors (users). Actors may be end users or other systems. Use cases may further elaborated using diagrams. Such diagrams identify the actor and the processes they perform.
System Sequence Diagram: A System Sequence diagrams (SSD) is a picture that shows, for a particular use case, the events that actors generate, their order, including inter-system events.
User interface document: Document that shows and describes the user interface.
Data model: A data model describes how data elements relate to each other. The data model is created before the design phase. Object-oriented designs map directly from the data model. Relational designs are more involved.
System lifecycle
The system lifecycle is a view of a system or proposed system that addresses all phases of its existence to include system conception, design and development, production and/or construction, distribution, operation, maintenance and support, retirement, phase-out, and disposal.
Conceptual design
The conceptual design stage is the stage where an identified need is examined, requirements for potential solutions are defined, potential solutions are evaluated, and a system specification is developed. The system specification represents the technical requirements that will provide overall guidance for system design. Because this document determines all future development, the stage cannot be completed until a conceptual design review has determined that the system specification properly addresses the motivating need.
Key steps within the conceptual design stage include:
Need identification
Feasibility analysis
System requirements analysis
System specification
Conceptual design review
Preliminary system design
During this stage of the system lifecycle, subsystems that perform the desired system functions are designed and specified in compliance with the system specification. Interfaces between subsystems are defined, as well as overall test and evaluation requirements. At the completion of this stage, a development specification is produced that is sufficient to perform detailed design and development.
Key steps within the preliminary design stage include:
Functional analysis
Requirements allocation
Detailed trade-off studies
Synthesis of system options
Preliminary design of engineering models
Development specification
Preliminary design review
For example, as the system analyst of Viti Bank, you have been tasked to examine the current information system. Viti Bank is a fast-growing bank in Fiji. Customers in remote rural areas are finding difficulty to access the bank services. It takes them days or even weeks to travel to a location to access the bank services. With the vision of meeting the customers' needs, the bank has requested your services to examine the current system and to come up with solutions or recommendations of how the current system can be provided to meet its needs.
Detail design and development
This stage includes the development of detailed designs that brings initial design work into a completed form of specifications. This work includes the specification of interfaces between the system and its intended environment, and a comprehensive evaluation of the systems logistical, maintenance and support requirements. The detail design and development is responsible for producing the product, process and material specifications and may result in substantial changes to the development specification.
Key steps within the detail design and development stage include:
Detailed design
Detailed synthesis
Development of engineering and prototype models
Revision of development specification
Product, process, and material specification
Critical design review
Production and construction
During the production and/or construction stage the product is built or assembled in accordance with the requirements specified in the product, process and material specifications, and is deployed and tested within the operational target environment. System assessments are conducted in order to correct deficiencies and adapt the system for continued improvement.
Key steps within the product construction stage include:
Production and/or construction of system components
Acceptance testing
System distribution and operation
Operational testing and evaluation
System assessment
Utilization and support
Once fully deployed, the system is used for its intended operational role and maintained within its operational environment.
Key steps within the utilization and support stage include:
System operation in the user environment
Change management
System modifications for improvement
System assessment
Phase-out and disposal
Effectiveness and efficiency of the system must be continuously evaluated to determine when the product has met its maximum effective lifecycle. Considerations include: Continued existence of operational need, matching between operational requirements and system performance, feasibility of system phase-out versus maintenance, and availability of alternative systems.

System investigation
During this step, current priorities that would be affected and how they should be handled are considered. A feasibility study determines whether creating a new or improved system is appropriate. This helps to estimate costs, benefits, resource requirements, and specific user needs.
The feasibility study should address operational, financial, technical, human factors, and legal/political concerns.
Analysis
The goal of analysis is to determine where the problem is. This step involves decomposing the system into pieces, analyzing project goals, breaking down what needs to be created, and engaging users to define requirements.
Design
In systems design, functions and operations are described in detail, including screen layouts, business rules, process diagrams, and other documentation. Modular design reduces complexity and allows the outputs to describe the system as a collection of subsystems.
The design stage takes as its input the requirements already defined. For each requirement, a set of design elements is produced.
Design documents typically include functional hierarchy diagrams, screen layouts, business rules, process diagrams, pseudo-code, and a complete data model with a data dictionary. These elements describe the system in sufficient detail that developers and engineers can develop and deliver the system with minimal additional input.
Testing
The code is tested at various levels in software testing. Unit, system, and user acceptance tests are typically performed. Many approaches to testing have been adopted.
The following types of testing may be relevant:
Path testing
Data set testing
Unit testing
System testing
Integration testing
Black-box testing
White-box testing
Regression testing
Automation testing
User acceptance testing
Software performance testing
Training and transition
Once a system has been stabilized through testing, SDLC ensures that proper training is prepared and performed before transitioning the system to support staff and end users. Training usually covers operational training for support staff as well as end-user training.
After training, systems engineers and developers transition the system to its production environment.
Operations and maintenance
Maintenance includes changes, fixes, and enhancements.
Evaluation
The final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements.
Life cycle
Management and control
SDLC phases related to management controls
SDLC phase objectives are described in this section with key deliverables, a description of recommended tasks, and a summary of related control objectives for effective management. It is critical for the project manager to establish and monitor control objectives while executing projects. Control objectives are clear statements of the desired result or purpose and should be defined and monitored throughout a project. Control objectives can be grouped into major categories (domains), and relate to the SDLC phases as shown in the figure.
To manage and control a substantial SDLC initiative, a work breakdown structure (WBS) captures and schedules the work. The WBS and all programmatic material should be kept in the "project description" section of the project notebook.[clarification needed] The project manager chooses a WBS format that best describes the project.
The diagram shows that coverage spans numerous phases of the SDLC but the associated MCD[clarification needed] shows mappings to SDLC phases. For example, Analysis and Design is primarily performed as part of the Acquisition and Implementation Domain, and System Build and Prototype is primarily performed as part of delivery and support.
Work breakdown structured organization
Work breakdown structure
The upper section of the WBS provides an overview of the project scope and timeline. It should also summarize the major phases and milestones. The middle section is based on the SDLC phases. WBS elements consist of milestones and tasks to be completed rather than activities to be undertaken and have a deadline. Each task has a measurable output (e.g., analysis document). A WBS task may rely on one or more activities (e.g. coding). Parts of the project needing support from contractors should have a statement of work (SOW). The development of a SOW does not occur during a specific phase of SDLC but is developed to include the work from the SDLC process that may be conducted by contractors.
Baselines
Baselines[clarification needed] are established after four of the five phases of the SDLC, and are critical to the iterative nature of the model. Baselines become milestones.
functional baseline: established after the conceptual design phase.
allocated baseline: established after the preliminary design phase.
product baseline: established after the detail design and development phase.

null | general_qa | What batting traits make a good baseball or softball hitter? | There are many traits that great baseball and softball batters share. Some of the most important are extreme confidence, sound batting mechanics, and coordination developed though a combination of talent and practice.
All great hitters share some consistencies in their batting mechanics such as their lower half mechanics, their hand and bat path, and their head and eye movement.
With their lower half mechanics they generate powerful torque from the ground up by timing the planting their feet in a balanced position and forcefully rotating and opening their hips. Hitting powerful line drives relies heavily on the barrel of the bat meeting the ball flush. Batters increase the odds of this by keeping their hands in, connected to the back shoulder, and having one palm facing up and one palm facing down for as long as possible as the bat path travels through the strike zone. Finally, all great hitters maintain consistent head and eye position throughout the motion.
There are many nuances of batting mechanics that all great hitters share but these are some of the most important. | null | null | null | 4182 |

null | closed_qa | Given this article about Operation Aurora, Which nation was beleived to be behund the attacks? | Operation Aurora was a series of cyber attacks conducted by advanced persistent threats such as the Elderwood Group based in Beijing, China, with ties to the People's Liberation Army. First publicly disclosed by Google on January 12, 2010, in a blog post, the attacks began in mid-2009 and continued through December 2009.
The attack was aimed at dozens of other organizations, of which Adobe Systems, Akamai Technologies, Juniper Networks, and Rackspace have publicly confirmed that they were targeted. According to media reports, Yahoo, Symantec, Northrop Grumman, Morgan Stanley, and Dow Chemical were also among the targets.
As a result of the attack, Google stated in its blog that it plans to operate a completely uncensored version of its search engine in China "within the law, if at all," and acknowledged that if this is not possible, it may leave China and close its Chinese offices. Official Chinese sources claimed this was part of a strategy developed by the U.S. government.
The attack was named "Operation Aurora" by Dmitri Alperovitch, Vice President of Threat Research at cybersecurity company McAfee. Research by McAfee Labs discovered that "Aurora" was part of the file path on the attacker's machine that was included in two of the malware binaries McAfee said were associated with the attack. "We believe the name was the internal name the attacker(s) gave to this operation," McAfee Chief Technology Officer George Kurtz said in a blog post.
According to McAfee, the primary goal of the attack was to gain access to and potentially modify source code repositories at these high-tech, security, and defense contractor companies. "[The SCMs] were wide open," says Alperovitch. "No one ever thought about securing them, yet these were the crown jewels of most of these companies in many ways—much more valuable than any financial or personally identifiable data that they may have and spend so much time and effort protecting."
History
Flowers left outside Google China's headquarters after its announcement it might leave the country
On January 12, 2010, Google revealed on its blog that it had been the victim of a cyber attack. The company said the attack occurred in mid-December and originated from China. Google stated that over 20 other companies had been attacked; other sources have since cited that more than 34 organizations were targeted. As a result of the attack, Google said it was reviewing its business in China. On the same day, United States Secretary of State Hillary Clinton issued a brief statement condemning the attacks and requesting a response from China.
On January 13, 2010, the news agency All Headline News reported that the United States Congress plans to investigate Google's allegations that the Chinese government used the company's service to spy on human rights activists.
In Beijing, visitors left flowers outside of Google's office. However, these were later removed, with a Chinese security guard stating that this was an "illegal flower tribute". The Chinese government has yet to issue a formal response, although an anonymous official stated that China was seeking more information on Google's intentions.
Attackers involved
Further information: Cyberwarfare by China
Technical evidence including IP addresses, domain names, malware signatures, and other factors, show Elderwood was behind the Operation Aurora attack. The "Elderwood" group was named by Symantec (after a source-code variable used by the attackers), and is referred to as the "Beijing Group" by Dell Secureworks. The group obtained some of Google's source code, as well as access to information about Chinese activists. Elderwood also targeted numerous other companies in the shipping, aeronautics, arms, energy, manufacturing, engineering, electronics, financial, and software sectors.
The "APT" designation for the Chinese threat actors responsible for attacking Google is APT17.
Elderwood specializes in attacking and infiltrating second-tier defense industry suppliers that make electronic or mechanical components for top defense companies. Those firms then become a cyber "stepping stone" to gain access to top-tier defense contractors. One attack procedure used by Elderwood is to infect legitimate websites frequented by employees of the target company – a so-called "water hole" attack, just as lions stake out a watering hole for their prey. Elderwood infects these less-secure sites with malware that downloads to a computer that clicks on the site. After that, the group searches inside the network to which the infected computer is connected, finding and then downloading executives' e-mails and critical documents on company plans, decisions, acquisitions, and product designs.
Attack analysis
In its blog posting, Google stated that some of its intellectual property had been stolen. It suggested that the attackers were interested in accessing Gmail accounts of Chinese dissidents. According to the Financial Times, two accounts used by Ai Weiwei had been attacked, their contents read and copied; his bank accounts were investigated by state security agents who claimed he was under investigation for "unspecified suspected crimes". However, the attackers were only able to view details on two accounts and those details were limited to things such as the subject line and the accounts' creation date.
Security experts immediately noted the sophistication of the attack. Two days after the attack became public, McAfee reported that the attackers had exploited purported zero-day vulnerabilities (unfixed and previously unknown to the target system developers) in Internet Explorer and dubbed the attack "Operation Aurora". A week after the report by McAfee, Microsoft issued a fix for the issue, and admitted that they had known about the security hole used since September. Additional vulnerabilities were found in Perforce, the source code revision software used by Google to manage their source code.
VeriSign's iDefense Labs claimed that the attacks were perpetrated by "agents of the Chinese state or proxies thereof".
According to a diplomatic cable from the U.S. Embassy in Beijing, a Chinese source reported that the Chinese Politburo directed the intrusion into Google's computer systems. The cable suggested that the attack was part of a coordinated campaign executed by "government operatives, public security experts and Internet outlaws recruited by the Chinese government." The report suggested that it was part of an ongoing campaign in which attackers have "broken into American government computers and those of Western allies, the Dalai Lama and American businesses since 2002." According to The Guardian's reporting on the leak, the attacks were "orchestrated by a senior member of the Politburo who typed his own name into the global version of the search engine and found articles criticising him personally."
Once a victim's system was compromised, a backdoor connection that masqueraded as an SSL connection made connections to command and control servers running in Illinois, Texas, and Taiwan, including machines that were running under stolen Rackspace customer accounts. The victim's machine then began exploring the protected corporate intranet that it was a part of, searching for other vulnerable systems as well as sources of intellectual property, specifically the contents of source code repositories.
The attacks were thought to have definitively ended on Jan 4 when the command and control servers were taken down, although it is not known at this point whether or not the attackers intentionally shut them down. However, the attacks were still occurring as of February 2010.
Response and aftermath
The German, Australian, and French governments publicly issued warnings to users of Internet Explorer after the attack, advising them to use alternative browsers at least until a fix for the security hole was made. The German, Australian, and French governments considered all versions of Internet Explorer vulnerable or potentially vulnerable.
In an advisory on January 14, 2010, Microsoft said that attackers targeting Google and other U.S. companies used software that exploits a hole in Internet Explorer. The vulnerability affects Internet Explorer versions 6, 7, and 8 on Windows 7, Vista, Windows XP, Server 2003, Server 2008 R2, as well as IE 6 Service Pack 1 on Windows 2000 Service Pack 4.
The Internet Explorer exploit code used in the attack has been released into the public domain, and has been incorporated into the Metasploit Framework penetration testing tool. A copy of the exploit was uploaded to Wepawet, a service for detecting and analyzing web-based malware operated by the computer security group at the University of California, Santa Barbara. "The public release of the exploit code increases the possibility of widespread attacks using the Internet Explorer vulnerability," said George Kurtz, CTO of McAfee, of the attack. "The now public computer code may help cybercriminals craft attacks that use the vulnerability to compromise Windows systems."
Security company Websense said it identified "limited public use" of the unpatched IE vulnerability in drive-by attacks against users who strayed onto malicious Web sites. According to Websense, the attack code it spotted is the same as the exploit that went public last week.[clarification needed] "Internet Explorer users currently face a real and present danger due to the public disclosure of the vulnerability and release of attack code, increasing the possibility of widespread attacks," said George Kurtz, chief technology officer of McAfee, in a blog update. Confirming this speculation, Websense Security Labs identified additional sites using the exploit on January 19. According to reports from Ahnlab, the second URL was spread through the Instant Messenger network Misslee Messenger, a popular IM client in South Korea.
Researchers have created attack code that exploits the vulnerability in Internet Explorer 7 (IE7) and IE8—even when Microsoft's recommended defensive measure (Data Execution Prevention (DEP)) is turned on.[dubious – discuss] According to Dino Dai Zovi, a security vulnerability researcher, "even the newest IE8 isn't safe from attack if it's running on Windows XP Service Pack 2 (SP2) or earlier, or on Windows Vista RTM (release to manufacturing), the version Microsoft shipped in January 2007."
Microsoft admitted that the security hole used had been known to them since September. Work on an update was prioritized and on Thursday, January 21, 2010, Microsoft released a security patch aiming to counter this weakness, the published exploits based on it and a number of other privately reported vulnerabilities. They did not state if any of the latter had been used or published by exploiters or whether these had any particular relation to the Aurora operation, but the entire cumulative update was termed critical for most versions of Windows, including Windows 7.
Security researchers continued to investigate the attacks. HBGary, a security firm, released a report in which they claimed to have found some significant markers that might help identify the code developer. The firm also said that the code was Chinese language based but could not be specifically tied to any government entity.
On February 19, 2010, a security expert investigating the cyber-attack on Google, has claimed that the people behind the attack were also responsible for the cyber-attacks made on several Fortune 100 companies in the past one and a half years. They have also tracked the attack back to its point of origin, which seems to be two Chinese schools, Shanghai Jiao Tong University and Lanxiang Vocational School. As highlighted by The New York Times, both of these schools have ties with the Chinese search engine Baidu, a rival of Google China. Both Lanxiang Vocational and Jiaotong University have denied the allegation.
In March 2010, Symantec, which was helping investigate the attack for Google, identified Shaoxing as the source of 21.3% of all (12 billion) malicious emails sent throughout the world.

null | general_qa | How can I make my bike more aerodynamic? | Assuming you are keeping your existing bike frame, the top two ways to decrease aerodynamic drag are to ensure you are comfortable riding in an aerodynamic position, and upgrading your wheel set and using road tires. Improving body positioning will have the most benefit at the lowest cost. Because wheel spokes are continuously cutting through air as you ride, they induce drag. Spokes on wheels with less aerodynamic drag allow for the wheels to roll with less resistance. Aerodynamic wheels are generally lighter which also decreases rolling drag. | null | null | null | 4193 |
