The CloneNotSupportedException is an exception in Java that is thrown to indicate that the clone() method in class Object was called to clone an object, but that object's class does not implement the Cloneable interface. Applications that override the clone() method can also throw this exception to indicate that an object could not or should not be cloned.
In this series of demystifying the tech trends, my colleagues and I will be looking at busting the buzzwords to help you keep on track. Concerned about puzzling parlance, analytics argot, techie terminology – or plain old jargon? This series breaks down words and concepts to give you the deepest insight and understanding into how to talk the talk in the world of tech, so you can engage in conversations with the confidence of being data literate.
When I was working at Google back in the mid 2000’s, we dealt with tens of billions of ad impressions a day, trained several machine learning models on years worth of historic data, and used frequently-updated models in ranking ads. The whole system was an amazing feat of engineering and there was no system out there that was even close to handling this much data. It took us years and hundreds of engineers to make this happen, today, the same scale can be achieved in any enterprise. Rapid innovation in cloud data technology and exponential growth in the number of new products and companies in the data and analytics space is what’s making this possible. A subset of these tools is often referred to as the “modern data stack.”
You use realtime communication every day. It is the simultaneous exchange of information between a sender and a receiver with almost zero latency. Internet, landlines, mobile/cell phones, instant messaging (IM), internet relay chat, videoconferencing, teleconferencing, and robotic telepresence are all examples of realtime communication systems.
Flask and Django are two of the most popular Python packages. More importantly, they are the two most preferred web frameworks you can use with the language. Both frameworks are open-source and offer excellent APIs for developers to build robust Python web applications. While both frameworks serve the same purpose, they take two philosophically opposed routes to achieve it. While Django offers a stable, all-inclusive toolkit for the many different aspects of backend programming, Flask strips away most of the fluff. It focuses on the barebones and core features through a lightweight and highly flexible API.
Object-oriented programming (OOP) is hard to achieve in a dynamic prototypical language like JavaScript. You have to manually stick to OOP principles because of language features like duck typing. This requires discipline, as nothing in the language enforces the principles. If a diverse team of developers with different backgrounds is involved, a codebase filled with good intentions can quickly become one chaotic mess. In this take, we will delve into proper OOP techniques in TypeScript, showing how the language automates a bunch of manual labor and encourages best practices. We will begin by talking a bit about duck typing, then go into the three pillars: encapsulation, inheritance, and polymorphism.
In this load test tutorial, you’ll learn how to use Postman for small-scale API testing. You’ll also learn about some shortcomings and challenges of the framework that can be solved by using a tool like Speedscale. Because HTTP services don’t have a graphical user interface, you’re forced to test web APIs by simulating requests from a known client so that you can control the traffic data. However, if you develop a client application with a graphical interface for testing, you’d be wasting time and resources that could be used in the development of the service itself.
While the title to this post is clearly playful, when it comes to customer success it’s all business. Our rapid growth has always been a function of our customers’ happiness. Regardless if it’s a new release or a service engagement, our internal focus revolves around a few key themes.
All product designers, builders and owners strive to create true ‘ah-ha!’ moments in the products they create. But how do you do so in an era of incremental innovation? GM of Design & Digital at Yellowfin, Tony Prysten, shares his experiences.
A common theme among most software testing organizations is their escalating interest in Test Automation. While test automation has grown in popularity, there are still many myths and biases surrounding it. Such myths can unknowingly create a self-limiting boundary and negatively impact the possibilities of test automation. In this article, I will discuss some common test automation myths and biases that people have towards test automation. Note: “!=” operator has been used throughout this article to denote inequality. If you are not familiar with this operator, please read it as “not equal to”.
The InstantiationException is a runtime exception in Java that occurs when an application attempts to create an instance of a class using the Class.newInstance() method, but the specified class object cannot be instantiated. Since the InstantiationException is an unchecked exception, it does not need to be declared in the throws clause of a method or constructor.
When it comes to providing the latest and greatest ETL and ELT tools, the platforms Stitch, Fivetran, and Integrate.io are all top contenders. That being said, each platform also has its own set of pros and cons. Ultimately, the best ETL/ELT platform for your company will largely depend upon the needs of your organization. So, which platform will reign supreme for your company in the Stitch vs Fivetran vs Integrate.io matchup? Read on to learn more about these three ETL/ELT platforms and to discover how the Stitch vs Fivetran vs Integrate.io matchup will play out.
Application programming interface (API) monetization is a process that allows businesses to generate revenue from their APIs. There are several different ways to do this, and the best approach depends on the specific API program and its features. This article will discuss API monetization strategy, the different types, and the benefits and drawbacks of each approach.
