The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help boost feelings of calmness, happiness and focus.

The document discusses techniques for evolutionary database development in an agile team. It recommends that the database administrator (DBA) work closely with other roles to iteratively refactor the database schema through small, frequent changes. It also emphasizes automated testing and deployment of database changes to safely evolve the database design over time.
This document discusses techniques for writing highly scalable Java programs for multi-core systems. It begins with an overview of hardware trends showing an increasing number of cores per chip. It then discusses profiling tools that can identify lock contention issues. The document provides best practices for Java programming including reducing locking scope, splitting locks, stripping locks, using atomic variables, and lock-free algorithms. It emphasizes using concurrent containers and immutable/thread-local data where possible.

This document provides an introduction to data visualization techniques including 2D scalar fields, quantitative vs qualitative representations, isocontours, marching cubes, direct volume rendering, transfer functions, vector fields visualization using streamlines and line integral convolution, and visualizing hierarchical, map, and social data. It discusses principles for representing ordered data with colors and representing different levels with different colors. It also covers speeding up techniques like octrees and extrema graphs and handling multiple data layers.
The document discusses applying behavior driven development (BDD) to refactor a legacy system. It describes starting with a 10+ year old complicated system without tests. The goal is to simplify and test the code to enable continuous integration and deployment. BDD is implemented through scenarios to design test cases, develop features incrementally, and provide regression testing. An automated test architecture is developed using scenarios for end-to-end and white box testing. Continuous deployment is enabled through incremental delivery and throughput throttling to simulate production. The system is made resilient through automatic incident recovery.
Java is a popular language for mobile development due to its portability across platforms. It allows development of apps for tasks like maps, email, chat, and games. Developers can target platforms like Android and Blackberry using Java with SDKs, IDEs, and emulators. The development process involves proposals, design, testing, and agile practices while addressing issues specific to mobile like concurrency, battery use, location services, and networks.

The document discusses differences in how web front-end standards are implemented across browsers. It covers topics like IE's hasLayout and block formatting contexts compared to specifications, line boxes and inline formatting contexts, differences between DOM attributes and JavaScript properties, and script optimization in Firefox's TraceMonkey engine.
The document discusses HTML5 features including Canvas, SVG, WebSockets, Web Storage, Web SQL Database, Audio/Video tags, and CSS3 properties like gradients, transitions and animations. It provides examples and links to resources about implementing these new technologies. Key HTML5 features like local storage, audio playback, and the Canvas API are highlighted in the context of enhancing the Douban Pulse application.
