Several years ago, I got the “Pro ASP.NET Web API” book. This article is the offshoot of ideas from this book, a little CQRS, and my own experience developing client-server systems. In this article, I’ll be covering: Why ASP.NET Core? ASP.NET Core provides many improvements over the ASP.NET MVC/Web API. Firstly, it is now one framework and not two. I really like it because it is convenient and there is less confusion. Secondly, we have logging and DI containers without any additional libraries, which saves me time and allows me to concentrate on writing better code instead of choosing and analyzing the best libraries. What Are Query Processors? A query processor is an approach when all business logic relating to one entity of the system is encapsulated in one service and any access or actions with this entity are performed through this service. This service is usually called {EntityPluralName}QueryProcessor. If necessary, a query processor includes CRUD (create, read, update, delete) methods for this entity. Depending on the requirements, not all methods may be implemented. To give a specific example, let’s take a look at ChangePassword. If the method of a query processor requires input data, then only the required data should be provided. Usually, for each method, a separate query class is created, and in simple cases, it is possible (but not desirable) to reuse the query class. Our Aim In this article, I’ll show you how to make an API for a small cost management system, including basic settings for authentication and access control, but I will not go into the authentication subsystem. I will cover the whole...
As a result of smartphones and mobile applications becoming so popular, web developers have been looking for ways to create mobile applications using JavaScript. This popularity resulted in the development of many JavaScript frameworks capable of running native-like applications on mobile devices. Currently, Cordova and React Native are the most popular choices. Cordova supports iOS, Android, and Windows Phone mobile platforms. With React Native, on the other hand, Android, iOS, and UWP are targets for developers. (UWP stands for Universal Windows Platform, Microsoft’s platform that allows the same application to run on Windows Phone 10 Mobile, XBox One and Windows 10.) From the surface, it appears that React Native and Cordova are occupying the same space. However, as with all technologies, there are aspects where one shines, and the other falls short. So, to get a better picture of each technology, and to learn their advantages and pitfalls, we will dive into details of each and compare them across different disciplines. Differences in Philosophy It’s important to remember that React Native’s tagline, “Learn once, write anywhere” differs from the usual cross-platform mantra, “Write once, run anywhere.” This leads to two things: Firstly, we can’t just take our existing React codebase from our web project and turn it into a mobile application in just a few clicks. However, React and React Native do share a lot of key concepts with one example being their component systems, and as a result, React Native feels instantly familiar. While React shares a lot of similarities with React Native, there are some core differences, which ranges from the way stylesheets are handled to the...
With Covid-19 hitting the headlines, it has forced most organizations to adapt to new practices and norms such as Social Distancing, Sanitization, and Remote Working. While the world is combating this epidemic, we also have cyber criminals who are indeed capitalizing on this crisis. The Coronavirus epidemic has created a fresh and unlikely cybersecurity challenge for most organizations around the world. Pre-COVID19, employees were accessing their corporate network through secured office laptops and devices. With the rise in employees working from home, enterprises have been forced to migrate to cloud services almost overnight. In this rapid rush, many security best practices have been overlooked. Cloud services like enterprise chat rooms, online office suites, and drives are seeing widespread use nowadays for file sharing and communication. This creates novel problems since there are more unsecured devices being used by workers that are lacking the latest security updates and patches. Therefore, with work from home becoming the new normal, Cyber Security strategies need to get sharper, stronger, and more relevant. Let’s face it, we all know that security bugs and privacy hacking practices are not new. The traditional approach to security has been to look for outsiders who may try to break in and steal confidential data. That dynamic has now changed with the risks coming from within so to speak. Employees who lack training in security best practices may end up causing the leak of sensitive organizational data. Cybersecurity leaders must be willing to look at the bad actors or employees with malicious intent as well. This emerging threat is a serious factor to consider since a sudden influx of unsecured devices...
AMY GOODMAN: This is Democracy Now!, democracynow.org, The War and Peace Report. I’m Amy Goodman. DAVID CARROLL: All of your interactions, your credit card swipes, web searches, locations, likes, they’re all collected, in real time, into a trillion-dollar-a-year industry. CAROLE CADWALLADR: The real game changer was Cambridge Analytica. They worked for the Trump campaign and for the Brexit campaign. They started using information warfare. AMY GOODMAN: New details are emerging about how the shadowy data firm Cambridge Analytica worked to manipulate voters across the globe, from the 2016 election in the United States to the Brexit campaign in Britain. We are continuing our look at the Oscar-shortlisted documentary The Great Hack, which chronicles the rise and fall of Cambridge Analytica. And we’re continuing with our four guests. Jehane Noujaim and Karim Amer are the co-directors of The Great Hack, which was just nominated for a BAFTA — that’s the British equivalent of the Oscars — as well as made it to the Academy Award shortlist for documentaries. Jehane and Karim’s past film include The Square. Jehane was the director of Control Room. Brittany Kaiser is also with us. She’s the Cambridge Analytica whistleblower who’s featured in the film. She has written the book Targeted: The Cambridge Analytica Whistleblower’s Inside Story of How Big Data, Trump, and Facebook Broke Democracy and How It Can Happen Again. She’s joining us in her first interview that she’s done after releasing a trove of documents on Cambridge Analytica’s involvement in elections around the world and other issues. And we’re joined by Emma Briant, a visiting research associate in human rights at Bard College who...
Australian experts suggest blockchain is an integral part to protecting Australia’s business and government from cyber attacks. A cyber security and blockchain forum with leading Australian experts and government officials has identified blockchain technology as a direct response to an increase in cyber attacks targeting the integrity of systems through manipulating data. Recently appointed Blockchain Australia CEO Steve Vallas held a panel discussion on July 30 regarding blockchain’s use-case in cyber security with experts from various fields being part of the 300+ attendees. The panel consisted of National Blockchain Lead Chloe White from the Department of Industry and Liberal Senator Andrew Bragg, CEO of cyber security firm CyberCX John Paitaridis, and founder and CTO of blockchain database firm ProvenDB Guy Harrison. The experts, with decades of experience in the cyber security sector, defined the emerging technology as a critical component in protecting Australia from future attacks. They further outlined that blockchain, although not a complete solution, should be considered by businesses across the board as the country works to keep ahead of would-be attackers. Blockchain is about data integrity During the panel, Paitaridis explained that attacks are increasing in frequency and severity, suggesting China was behind the major state actor attacks from June that threatened many industries including the Australian government: “In June this year, the Australian Prime Minister announced an ‘unnamed state actor’, you can read into that — China — as being targeting businesses and government agencies across Australia as part of a large, dedicated, persistent scale attack.” These cybersecurity breaches have increased by almost 80% in the last 12 months with a specific adjustment in their...
