Massive Streaming Analytics with Spark Streaming
Streaming data allows for faster reactions and more profits by enabling real-time processing compared to typical batch analysis workflows. Prediction is more valuable than rule-based categorization and clustering because it allows for pattern discovery, adaptation to changing data, and "smart thinking". Spark Streaming is presented as a tool for building streaming architectures with ingestion, processing, and serving layers. A demo of card transaction analysis with real-time classification, fraud detection, and alert generation is shown.

Pragmatic Architecture
Friday, March 19 - 1:00 p.m.
Presented By: Ted Neward
Ted Neward, delivers brass-tacks advice on how to make decisions regarding programming languages to use (Java, .NET, even FoxPro); architectural approaches to take (n-tier, client/server); user interface approaches to take (Smart/rich client, thin client, Ajax); and even how to communicate between processes (Web services, distributed objects, REST). Ted understands the goals of an application architecture
and why developers should concern themselves with architecture in the first place. In this session, he dives into the meat of the various architectural considerations available; the pros and cons of JavaWebStart, ClickOnce, Windows Presentation Foundation, SWT, Swing,
WinForms, Struts, WebForms, Ajax, RMI, .NET Remoting, JAX-WS, ASMX, Windows Communication Foundation, Windows Workflow Foundation, JMS, MSMQ, transactional processing, and more. The basic architectural discussion from the first part is, with the aid of audience
interaction, applied to a real-world problem, discussing the performance and scalability ramifications of the various communication
options, user interface options, and more.

Pragmatic Architecture for Agile Teams - GeeCON 2014
The talk I gave on GeeCON Prague 2014 on doing pragmatic architecture, using lean methods and practical documentation.
Pragmatic Architecture in .NET
The document discusses pragmatic architecture approaches in .NET. It outlines three levels of architecture - Level 1 using simple patterns like active record, Level 2 with some separation of concerns, and Level 3 using domain-driven design and other complex patterns. The key points are that the simplest approach that could work is best, context matters, and best practices have both benefits and costs to consider for the project.
Pragmatic Architecture for Agile Teams
The document discusses pragmatic architecture for agile teams. It argues that architecture is too important to be left solely to architects and should be a team responsibility. It recommends balancing agility and discipline by designing enough architecture early while still prototyping. Key aspects of good architecture include getting all hands on deck in architectural decisions, prioritizing local team decisions while ensuring feedback, and documenting relationships not clear from code like domain dictionaries, component diagrams, and integration diagrams.
Design Thinking Process
This document outlines the design thinking process which includes understanding the problem, researching benchmarks and insights, identifying opportunities and problems, designing a strategy, prototyping solutions, and implementing the final solution. The process involves studying the problem, researching other solutions, looking for unidentified opportunities, gathering all potential problems, designing objectives to solve problems, testing prototype models, and developing the best solution.
Theory of architecture
The document discusses several architectural theories and styles including deconstructivism, postmodernism, parametric design, futuristic design, and cybertecture. Deconstructivism focuses on non-rectilinear forms and fragmented features. Postmodernism incorporates references from multiple historical styles. Parametric design uses computer software to generate complex shapes. Futuristic designs presented use bio-inspired vertical designs and sustainability. Cybertecture proposes buildings that incorporate technology, multimedia, and intelligence.
Basic Theory of Architecture
The document provides an introduction to the basic elements and concepts of architecture. It discusses key spatial elements like points, lines, planes and volumes that define architectural space. It describes different types of planes such as vertical wall planes, horizontal base planes that can be elevated or depressed, and overhead planes like ceilings and roofs. It explains how these different planes are used to define, articulate and organize interior and exterior spaces. Linear elements like columns, walls and structural frames are also summarized as defining edges and corners of spaces while providing structure.
03 architectural principles & elements
The document discusses the primary architectural elements of point, line, plane and volume. It defines each element and provides examples of how they are used in architectural design. A point becomes a line with length and direction. A line extended forms a plane with length, width and surface. A plane extended creates a volume with three dimensions of length, width and depth. The elements are used to define spaces, structures and forms in architecture.

Generating Architectural Concepts & Design Ideas
The document discusses the history and development of artificial intelligence over the past 70 years, from early research into neural networks in the 1940s to modern deep learning techniques. While AI has made tremendous progress, fully human-level AI remains challenging to achieve and raises complex issues around safety, ethics, and its impact on society that require careful consideration and oversight. Overall progress in AI has occurred in steps by incorporating more data and modeling increasingly complex phenomena, but fully general human intelligence remains a long-term goal that will require ongoing research.

agile microservices @scaibo
The document discusses agile microservices and their advantages over monolithic architectures. It describes how to decompose a monolithic real estate management application into independent microservices for properties, facilities, and engineering. Microservices allow for improved independence, speed of development, automation, and use of different technologies. Inter-service communication can occur over REST, HTTP, or AMQP, while an API gateway pattern hides service complexity from clients. Cloud computing platforms like Docker and Convox can deploy and manage containerized microservices. The Internet of Things connects physical devices to these services over protocols like MQTT and WebSocket.

The micro-service architecture, which structures an application as a set of small, narrowly focused, independently deployable services, is becoming an increasingly popular way to build applications. This approach avoids many of the problems of a monolithic architecture. It simplifies deployment and let’s you create highly scalable and available applications. In this talk we describe the micro-service architecture and how to use it to build complex applications. You will learn how techniques such as Command Query Responsibility Segregation (CQRS) and Event Sourcing address the key challenges of developing applications with this architecture. We will also cover some of the various frameworks such as NodeJS and Spring Boot that you can use to implement micro-services.
Migrando aplicaciones SAP a AWS
This document discusses migrating SAP applications to AWS. Some of the key points discussed include:
1) Migrating SAP systems to AWS can be done in several ways such as backup and restore, classical SAP migration tools, or third party migration tools.
2) AWS services that can help with migration include services for transferring data over the wire like S3, VPN, or Direct Connect as well as the AWS Import/Export service.
3) Once migrated, running SAP on AWS provides benefits like speed, security, flexibility, and agility through services like AWS Quick Starts for SAP, high performance compute instances optimized for SAP, and integration with other AWS services.

This document provides a short introduction to MongoDB. It discusses that MongoDB is a scalable, high-performance, open source, document-oriented database that stores JSON-like documents. It then demonstrates some basic MongoDB operations like insert, find, update, remove, and indexing documents in a collection. The document recommends further resources on additional MongoDB features and capabilities.
Geo & capped collections with MongoDB
Capped collections in MongoDB allow you to limit the size and number of documents in a collection. This is useful for applications that involve logging, news feeds, or caching where collections need to be bounded. While documents cannot be deleted or updated, objects are returned in insertion order and the collection size is prevented from growing out of control. Geospatial indexing allows finding documents close to a location point, making it useful for location-based services. Real world examples of using capped collections include activity feeds, event logging, caching, and data pages.

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
