The document discusses various aspects of decision making including defining decision making, factors that influence decisions, the importance of rational decision making, and challenges with delayed decisions. It provides a 6-step decision making model and includes case studies about choosing an education path and deciding whether to divert a train to save some children at the expense of one child. Key lessons are that acquiring knowledge helps decision making, rational decisions consider all options and consequences, and hasty decisions may not always be the best choice.

Graph databases are an alternative to relational databases for modeling connected data. They are well-suited for problems involving relationships across multiple degrees of separation and different data types. Graph databases represent data as nodes and relationships, allowing for flexible traversal of connections. The presentation introduces graph database concepts and demonstrates how to model and query data using the Neo4j graph database.
This document introduces graph databases as an alternative to relational databases for modeling data with complex relationships. It discusses how graph databases can be used to efficiently find connections between entities, such as finding the shortest path between two actors in a movie database. Examples are given of domains where graph databases are commonly used, like social networks, mapping, and bioinformatics. The document also provides an overview of Neo4j, a popular graph database technology.
This document provides an overview of design patterns, including:
1) Design patterns are general solutions to common programming problems and help simplify code structure by promoting loose coupling and high cohesion.
2) Common design patterns include Strategy, Decorator, Observer, and Chain of Responsibility. Strategy defines behaviors through a common interface. Decorator adds behaviors dynamically. Observer uses publish-subscribe to broadcast events. Chain of Responsibility passes requests between handlers in a chain.
3) Design patterns derive from each other - for example, Decorator and Observer are forms of Chain of Responsibility that always run all handlers. Patterns help decrease coupling and increase cohesion in code.
Application modelling with graph databasesJosh Adell
?
Applications are built around domain and business concepts. As developers, we model these concepts and their relationships all the time in our heads, on whiteboards, and in code. Then we perform mental gymnastics translating objects and relationships into tables, rows and columns. Wouldn't it be better if our data storage thought the same way we do? This talk will describe a few types of problems that relational databases and many contemporary NOSQL solutions have trouble modeling, and how graph databases are a solution to those problems. Along the way, attendees will be introduced to the graph database Neo4j, will see how to interact with it via the Cypher query language, and learn how they can start modeling their own application domains as graphs.
"Dependency injection" (DI) seems like one of those hot buzzwords that will solve all your problems. But what is DI really? How does it help keep code clean and maintainable? And how do you take a legacy codebase and rewrite it to take advantage of DI? This talk takes an application written without DI and walks through the steps for "injecting" DI into the code. Learn the difference between "dependency injection" and "dependency injection containers". See how DI makes things like event-driven architectures simple to implement. And learn how DI leads to code that is easier to debug and test.
Roundabouts provide environmental, economic, and safety benefits over traditional intersections. They reduce greenhouse gas emissions by decreasing idling time and promoting continuous traffic flow. Construction and maintenance costs are often lower for roundabouts which do not require traffic signals or expensive infrastructure. Multiple studies show roundabouts reduce collisions and injuries at intersections by up to 90% by lowering speeds and eliminating high-risk collision angles. Washington state is promoting roundabouts as part of its strategy to reduce transportation emissions and meet sustainability goals.

The document discusses how graph databases can be used to model application data with relationships. It provides examples of using graph databases to model social networks, access control lists (ACL), and company organizational structures. Relational databases are not well-suited for modeling relationships, while graph databases allow querying and traversing relationships through nodes and edges. The document encourages using the right tool for the job and considering a graph database for applications where relationships are important.
The document provides an overview of upstream oil and gas exploration and production processes in India. It discusses key steps in the exploration cycle including surveys, drilling, reservoir analysis, and production. It covers geological concepts like source rocks, migration, traps, and basin formation. Key methods are outlined, such as seismic acquisition and different trap types. The importance of inputs from geology, geophysics, geochemistry is highlighted. Drilling and production activities are also summarized. India has 26 sedimentary basins but only 7 have yielded commercial oil and gas discoveries to date.
This document provides an overview of a training session on fans and blowers for energy efficiency. It discusses the different types of fans and blowers, how to assess their performance and efficiency, and identifies various opportunities to improve energy efficiency, such as choosing the right fan for the application, reducing system resistance, operating fans close to their best efficiency point, regular maintenance, and controlling air flow. The training covers centrifugal and axial fans, centrifugal and positive displacement blowers, and recommendations for improving fan system efficiency through proper selection, installation, operation and maintenance practices.
