Hadoop: The Rise of the Modern Data Lake Platform

Hadoop, while it may be synonymous with big data, and while it may be free to access and work with, engineering teams globally will admit that behind every Hadoop undertaking is a major technical delivery project.

Failures are so commonplace that even the experts don’t have great expectations of 2017: at the recent Gartner Data & Analytics Summit in Sydney, research director Nick Heudecker claimed that 70% of Hadoop deployments in 2017 will either fail to deliver their estimated cost savings or their predicted revenue.

It shouldn’t come as a surprise. Hadoop was designed for big data storage, but it wasn’t designed as an actual big data application. Hadoop and Spark are incredible enabling technologies.

Implementing DevOps: 5 Obstacles to Overcome

DevOps implementation is currently “all over the map,” said Jeff Sussna, founder and principal of Ingineering.IT and author of Designing Delivery: Rethinking IT in the Digital Service Economy. “There are some companies that we see at the enterprise DevOps conferences that are all in and making really comprehensive progress. In general though, the majority of companies I see are sort of grappling with it bit by bit, still trying to understand what it is and how to do it.”

Research shows that positive results — including faster deployments, fewer service problems, and more employee loyalty — await those who get it right.

Here are five common challenges enterprises encounter on their DevOps journeys, to help prepare you to tackle any difficulties that may arise.

Versioning a REST API in Kubernetes with Nginx Ingress Controller

An ingress makes it easy to route traffic entering a Kubernetes cluster through a load balancer like NGINX. Beyond basic load balancing and TLS termination, an ingress can have rules for routing to different backends based on paths. The NGINX ingress controller also allows more advanced configurations such as URL rewrites.

In this post, we’ll use ingress rules and URL rewrites to route traffic between two versions of a REST API. Each version is deployed as a service (api-version1 and api-version2). We will route traffic with path /api/v1 to api-version1, and /api/v2 to api-version2.

The sample application

We’ll be using a super simple ASP.NET Core application. Here’s the Configure() method in Startup.cs:

Explained: Neural Networks

In the past 10 years, the best-performing artificial-intelligence systems — such as the speech recognizers on smartphones or Google’s latest automatic translator — have resulted from a technique called “deep learning.”

Deep learning is in fact a new name for an approach to artificial intelligence called neural networks, which have been going in and out of fashion for more than 70 years. Neural networks were first proposed in 1944 by Warren McCullough and Walter Pitts, two University of Chicago researchers who moved to MIT in 1952 as founding members of what’s sometimes called the first cognitive science department.

Neural nets were a major area of research in both neuroscience and computer science until 1969, when, according to computer science lore, they were killed off by the MIT mathematicians Marvin Minsky and Seymour Papert, who a year later would become co-directors of the new MIT Artificial Intelligence Laboratory.

9 Superheroes for Crack Security Teams

Every great computer security team has a synergistic collection of skilled professionals who work well together to meet common goals. The team may debate a solution, but once a decision is made, everyone works hard to execute with no hard feelings. Good teams expect constant change and disruption. They know whatever it is they are trying to accomplish will likely be harder than anticipated.

When I encounter successful teams, distinct roles emerge among the group. Different organizations require different mixes of players, but these archetypes pop up again and again.

The world has reached a key moment in the history of the way we work. We have entered a new business environment, dictated by rapid changing technological variables that create an entirely new economic landscape. Exponential growth of our interconnected world forces us to see the world anew. The 21st century asks for a different mindset now the rules of the game have fundamentally changed.

In this game it is not anymore relevant to optimize an organization’s efficiency based on a stable set of known variables. Instead, there’s a strong need to adapt as fast as possible to increasingly complex working conditions. Efficiency has to make place for engagement and adaptability. The organizations that know how to fully engage their employees and those who are natives in this information-rich, densely interconnected world of the 21st century are the ones that thrive.

Working with Swagger

RESTful services have been popular for quite some time now. They are widely-used, primarily for improved performance, ease of use and maintenance. Swagger is a popular API for documenting your RESTful Web APIs. You need some way to document your RESTful services to know the endpoints and the different data models used in the request and response payloads. This article presents a discussion on how we can use Swagger to document our Web APIs easily.

What is Swagger? Why is it needed?

Swagger is a framework that can be used for describing and visualizing your RESTful APIs. Swagger provides a simple, yet powerful, way to represent your RESTful APIs so that the developers using those APIs can understand the endpoints and the request and response payloads in a much better way. The success of your API largely depends on proper documentation as proper documentation helps the developers understand ways to consume your API better. Here’s exactly where Swagger comes to the rescue.
