Patterns for organic architecture codedivemagda3695
This document is a diary entry by Jarosław Pałka about patterns of organic architecture. It discusses using metrics like complexity and number of changes to identify stable and fragile parts of a codebase. It also talks about refactoring incrementally with user stories, modularizing based on stability, and transforming a system design through an architectural process focused on understanding needs and allowing for design flexibility. The overall message is that architecture is an ongoing process of understanding problems, identifying constraints, and evolving a system's design for improved resilience through principles like separation of concerns, asynchronous communication, and self-organization.

The document discusses the history and evolution of mocking tools, from early mocking frameworks like JMock and EasyMock to the rise of Mockito. It notes key events like the introduction of the concept of "mock objects" for unit testing in 2000 and Tammo Freese's work on EasyMock in 2002. The document also provides guidance on best practices like "mock roles not objects" and emphasizes that test code quality is important and that tests should make production code refactoring easier. It highlights Mockito's popularity and ease of continuous deployment with automated release notes.
This document discusses ways to secure web applications from CSRF attacks. It describes how cookies and anti-forgery tokens can be used to authenticate requests and prevent request forgery. It provides examples of how attackers can hijack user sessions by stealing cookies and explains how to defend against these attacks using token-based validation. The document also addresses challenges in securing single-page apps and REST APIs and provides solutions like using a client-side API wrapper to generate and validate tokens for requests.
Gradle is an open-source build automation tool that provides a consistent automation workflow. It is developed by Gradleware, which employs around 7 engineers who release Gradle every 6 weeks through automated testing and continuous integration processes. Gradle scales to build very large projects with thousands of subprojects through features like caching, parallelization, and its daemon.
Big data is characterized by volume, velocity, and variety. It refers to data that is too large and complex for traditional data management tools to handle. Examples are provided of the massive amounts of content, videos, and messages generated every day. Hadoop is commonly used to collect, store, and analyze big data using technologies like HDFS, MapReduce, HBase, Hive, Pig, and Hadoop YARN. The future of big data is described as being real-time with low latency capabilities using technologies like Apache Drill and Storm.
IBM SoftLayer is a global cloud computing provider that hosts over 21,000 customers in 140 countries using its 13 data centers and 17 network points of presence. SoftLayer offers on-demand cloud computing resources including servers, storage, networking and other services that customers can provision and manage through a robust API or web-based portal. The platform provides users flexibility in deploying hybrid cloud architectures combining on-premise, private cloud and public cloud resources under a common management interface.
ARnav is an augmented reality navigation company led by CEO Adam Mencwal that provides location-based augmented reality and turn-by-turn navigation features. In the next year, ARnav plans to integrate with partner trail services, release an API and offline map packages, and develop indoor positioning and navigation for blind people. ARnav has won several startup competitions and accelerator programs and their technology could integrate with augmented reality displays like Google Glass.
The document outlines four values of the Agile Manifesto:
1) Individuals and interactions over processes and tools.
2) Working software over comprehensive documentation.
3) Customer collaboration over contract negotiation.
4) Responding to change over following a plan.
Akamai is a leading content delivery network founded in 1998 with over 150,000 servers in 81 countries. It delivers up to 30% of worldwide web traffic and accelerates daily traffic of over 10 terabits per second. Akamai serves the top media companies, ecommerce sites, banks, newspapers, social media sites, computer manufacturers, and anti-virus companies. The presentation discusses Akamai's global intelligent platform and how it leverages trends in media, mobile, cloud, big data, and security to optimize cloud services and protect against cyber attacks.

reflecting deteriorating structure, increases unless work is done to
maintain or reduce it.”
