The document discusses the Guardian's transition from using relational databases to NoSQL databases like MongoDB. It describes the early, mid, and modern periods of the Guardian's technology stack, moving from bespoke systems to vendor CMS platforms to monolithic Java applications. Problems with scaling and complexity motivated experimenting with partial NoSQL solutions and APIs. MongoDB was ultimately chosen as it allows flexible schemas, complex queries, and easy scaling similar to relational databases but with simpler implementation. The first project to use MongoDB is replacing the user identity system stored in Oracle.

JSP (JavaServer Pages) allow embedding Java code within HTML/XML pages to create dynamic web content. Key points: - JSP pages are compiled into Java servlets to generate the HTML response. This means JSP have access to full Java APIs and can be efficiently handled by the server. - It is recommended to separate presentation logic in JSP from business logic in Java classes to improve modularity. This can be done using JavaBeans, tag libraries, and MVC pattern. - Examples demonstrate using JSP scriplets and expressions to output dynamic data, JavaBeans to encapsulate data in reusable objects, and tag libraries to access beans and simplify JSP code. Form submission examples pass

Using Model-View-Controller as a pattern to describe stateless HTTP interactions has always been a bit of a kludge. There simply hasn't been a better pattern web applications -- until now. ADR (Action-Domain-Responder) represents a refinement of generic MVC as an application architecture specifically tuned to the web. In this talk, we will discuss various patterns of overall application architecture, including MVC, MVP, PAC, DCI, RMR, and others. We will find out how the ADR pattern arises from generic MVC, and how it provides a better description of how web applications actually work. Finally, we will go over examples of how to architect an ADR application, as well as how to convert from an MVC architecture to an ADR one.

The document discusses the health triangle, which measures three aspects of health: physical, mental, and social. Physical health deals with body functioning and includes exercise, nutrition, sleep, avoiding drugs and alcohol, and maintaining a healthy weight. Mental health relates to thinking, feelings, and coping, and encompasses learning, managing stress, and avoiding mental illness. Social health involves relationships with others through public health, family, and peers. The health triangle emphasizes making good choices across all three areas to reduce disease risk and promote overall well-being.

The document discusses load balancing techniques used to distribute workloads across multiple servers or resources. It begins with an introduction to load balancing and its benefits, such as increased capacity and continued service during failures. It then describes three main methods for load balancing in Linux: virtual server via NAT (VS/NAT), virtual server via tunneling (VS/TUN), and virtual server via direct routing (VS/DR). Each method forwards requests to servers differently while maintaining a single virtual IP address for clients. VS/NAT rewrites packets, VS/TUN uses encapsulation, and VS/DR directly routes packets on a shared LAN. The document provides examples and compares the advantages and disadvantages of each approach.

Human values are important ideals shared by a culture regarding what is good and desirable. These values determine whether people feel desire, happy, unhappy, prosperous, or deprived.

The document discusses and compares different API description languages (APIs), including RAML and Swagger. It provides an overview of each tool's features and capabilities. The document also shares the author's experiences using RAML and Swagger to describe sample APIs. While both APIs are useful for documentation, the author found RAML better suited for designing APIs first before coding, while Swagger integrates more tightly with code.

Just a few years back, lack of a standard way to document, govern or describe a contract for the APIs acted as a deterrent to API adoption within the enterprise. WSDL 2.0 and WADL provided early support, but they couldn’t truly capture the essence of RESTful APIs. Recently we have seen the emergence of several description languages. New ways to describe and document APIs have emerged such as Swagger, RAML, API Blueprint and others, each taking a slightly different approach.

This document discusses API description languages (APIs), comparing Swagger and RAML. It provides an overview of each specification and demonstrates how to define a sample wishlist API using Swagger via swagger-node-express and RAML. While both work well for RESTful APIs, RAML allows for more robust modeling and top-down design capabilities. The document considers issues like documentation approaches and generating documentation from code versus design.

This document provides an overview of JavaScript, including: - JavaScript can run in browsers without needing Java and is used for client-side scripting. It allows dynamic interactions with web pages. - JavaScript code can be included inline, embedded in <script> tags, or linked externally from .js files. External is preferred for maintenance. - Variables, data types, operators, and control structures are explained. Objects are collections of properties and methods. - Client-side scripting benefits include offloading processing to clients and faster responses to user events. Disadvantages include lack of JavaScript support and cross-browser inconsistencies. - AJAX made JavaScript more important by enabling asynchronous data requests without blocking the browser.
