Support for dependency injection is built into ASP.Net Core, Microsoft’s open source, cross platform, lean, and modular framework for building high performance, scalable web applications. In ASP.Net Core, both framework services and application services can be injected into your classes, rather than being tightly coupled. In this article we’ll look at how we can work with dependency injection in ASP.Net Core.Dependency injection (also known as DI) is a design pattern in which a class or object has its dependent classes injected (passed to it by another class or object) rather than create them directly. Dependency injection facilitates loose coupling and promotes testability and maintenance. Moreover, dependency injection allows you to change your implementations without having to change the classes or interfaces that leverage those implementations.[ Microsoft .Net Core 2.0: Everything you need to know. | Why .Net Core is finally ready for prime time. | .Net Framework … [Read more...] about How to use dependency injection in ASP.Net Core
ETL is dead
Extract, transform, and load. It doesn’t sound too complicated. But, as anyone who’s managed a data pipeline will tell you, the simple name hides a ton of complexity.And while none of the steps are easy, the part that gives data engineers nightmares is the transform. Taking raw data, cleaning it, filtering it, reshaping it, summarizing it, and rolling it up so that it’s ready for analysis. That’s where most of your time and energy goes, and it’s where there’s the most room for mistakes.If ETL is so hard, why do we do it this way?The answer, in short, is because there was no other option. Data warehouses couldn’t handle the raw data as it was extracted from source systems, in all its complexity and size. So the transform step was necessary before you could load and eventually query data. The cost, however, was steep.[ Also on InfoWorld: What is data mining?

Centralized security in the cloud: the best enterprise security model
It’s 6:00 a.m. on a Monday morning. You get an automated text from your security systems that a DDOS attack was attempted, but new security policies downloaded several hours earlier proactively protected the systems from the attacking IP address. All is well. The alternative is not good—meaning that you had no idea of the DDOS attack, and now you’re playing cloud security whack-a-mole to fend off the attack until you can put more permanent solutions in place. Of course, other types of breaches could be much worse, in terms of their impact on the enterprise. [ Working with data in the cloud requires new thinking.

What is Google Grafeas? Better auditing for containers
The software we run has never been more difficult to vouchsafe than it is today. It is scattered between local deployments and cloud services, built with open source components that aren’t always a known quantity, and delivered on a fast-moving schedule, making it a challenge to guarantee safety or quality.The end result is software that is hard to audit, reason about, secure, and manage. It is difficult not just to know what a VM or container was built with, but what has been added or removed or changed and by whom.

The drivers and social responsibility of automation
With machines come automation. And with automation comes a huge shift in how we live. What will the future of work look like? What does automation mean for humanity’s collective and individual purpose? What role will automation play in the social and economic displacement of people?There’s a tendency to take a negative viewpoint where automation is involved. But the reason so many of us are pursuing this path forward is that it promises the potential to change society for the better.Here are just a few examples of how automation can positively reshape our lives.The reduction of laborWorking longer hours doesn’t translate into comparable output. In fact, the longer our hours become, the more inefficient we get. Long hours are correlated with ill health and lower performance, costing US companies an estimated $300 billion each year.

AI, IoT, and the hybrid cloud: the triumvirate of IT’s future
Information technology systems of the future are increasingly focused on where data is generated and processed, how it’s delivered and collected, and how quickly this data can move. Finding the most efficient path is key.Two of the most significant trends are the internet of things (IoT) and artificial intelligence (AI), which fit together like hand in glove. In a very simple form, IoT is about a multitude of devices exchanging data from a multitude of data points, which are being collected in a plethora of ways and on a plethora of platforms. That data must be quickly analyzed and in most cases, sent to the next level for further processing.Meanwhile, AI is about programmatically manipulating this big data to make real-time and time-sensitive decisions. The only way to build for this technological union is with a hybrid multicloud platform.

Getting started with Twilio account security using Node.js and MongoDB
One of the first considerations for developers building mobile and web apps is how to handle account security, namely how they’re going to protect and authenticate their users and their data. The days where a username and password was sufficient to protect accounts are long behind us, and we’re reminded of this nearly every day in the form of large-scale breaches, high-profile account takeovers, or massive digital heists. Andrew Baker is a developer-educator at Twilio. Adding stronger account security such as two-factor authentication (2FA) to your app is one of the simplest ways to increase security, protect users from cyberattacks, and build trust in your product, all while maintaining a smooth user experience.This quick-start guides you through building a Node.js, AngularJS, and MongoDB application that restricts access to a URL.

6 essential Python libraries for Python programming
Python has seen wide adoption across industries and disciplines by dint of being easy to work with. But it has also been aided by a wealth of third-party projects—libraries, add-ons, and complementary development efforts—that extend the language to an ever widening range of use cases.Some of these projects, like PyInstaller and WxPython, shine for Python developers who are building desktop and end-user apps. Others, like PyPy, are used to give server-side Python apps extra oomph. And others, like PBR, CFFI, and MyPy, are useful for developing all kinds of Python apps, no matter where they might run.

How to use Redis for real-time metering applications
Roshan Kumar is senior product manager at Redis Labs. Metering is not just a simple counting problem. Metering is often confused with measuring, but it is usually more than that. Metering does involve measuring, but as an ongoing process, usually with the goal of regulating the usage or flow of a resource over time. Modern applications incorporate metering in many different ways, ranging from counting people, objects, or events to regulating usage, controlling access, and allocating capacity.Metering solutions generally must process large volumes of data while meeting stringent performance requirements. Depending on the scale of the solution, counting and metering might involve thousands if not millions of updates to a database every second. The primary requirements of a database to support such a solution are high throughput for write operations and low (sub-millisecond) latency for responses.Redis, the open source in-memory database platform, delivers both of these benefits … [Read more...] about How to use Redis for real-time metering applications
Using Containers to Reduce Public Cloud Costs
Being a chief information officer or IT manager can be difficult, but it’s rarely boring. Given the accelerating pace of technological change, as soon as these professionals become comfortable with some cutting-edge technology, another compelling advance demands their attention.For many IT leaders, containers have become one of the top items on their “to-do” lists. These standards-based code wrappers emerged from the open source community a few years ago, and have experienced rapid maturation and increasing adoption ever since.Containers promise a range of benefits, including many related to public cloud deployments. But the technology is new enough that it can still be quite challenging for many companies to fully exploit its potential.Unlike virtual machines, which run on top of a hypervisor layer and contain their own operating system instances, applications, and support libraries, containers can be much more compact and faster executing.
