Robotic process automation (RPA) is a technology used to automate manual, rule-based, repetitive tasks within your business processes. This can help free up human workers so they can focus more on the activities that require human logic, reasoning, and emotion. RPA can also be used as a quick and easy way to connect to legacy systems that don't use application programming interfaces (APIs).

There can be confusion out there given the size of the JS ecosystem. The differences seem pretty trivial, as a lot of tools seem to work in both limited and expanded capacities. But knowing the original or primary intent of a tool like React.js (it’s a library), can make it easier to grasp how it works and with which other JS tools. But this is where the distinctions become important – understanding the role of a progressive framework like Nest.js and how we got here.

Founding a developer-first startup isn’t quite the same as starting a regular company. When your primary focus is on creating products to sell to developers, you need to build a sales strategy around those developers’ needs. The occasional email with a ‘click here for a demo’ button just won’t cut it. Instead, it’s time to work on your content strategy. Why take our word for it?

API providers need to understand how their consumers are using their APIs. Usage metrics are essential because they tell you about API adoption, how your API is growing over time, and which endpoints are seeing more (or less) use. When you look at API usage metrics, you should be measuring the active users on your API in the sense that most closely aligns with your service.

Core Web Vitals are a set of metrics that allow you to determine how fast, visually stable and responsive your site is. The front-end takes the bulk of the responsibility to make sure that your website is scoring highly in each of these metrics, so in this blog post I will outline what we should be doing (as well as what we should be avoiding) to score highly in them.

API providers need to observe their APIs to get meaningful data about whether and how they are consumed in practice. API observability is a form of monitoring that passively logs API traffic to an observability service. Different from traditional API monitoring, with API observability you: Monitor interactions to improve developer experience Understand how customers use your API Troubleshoot your API Observing REST APIs is well understood and supported, but not every API is a REST API.

Typescript is a free-to-use programming language. This means that Typescript is a combination of JavaScript and other characteristics. Typescript is a superset of JavaScript, which means it contains all of the features of JavaScript plus a few more. JavaScript is an interpreted, lightweight programming language. It's a language for dynamic programming. JavaScript does not support multithreading or multiprocessing. It's used in web development to make HTML pages look better.

Let's face it. Nobody wants to see a broken, empty page while surfing the web. It leaves you stranded and confused. You don't know what happened or what caused it, leaving you with a bad impression of the website. It is often better to communicate the error and let the user continue to use the app. The user will get less of a bad impression and can continue to use its features. In today's post, we'll go through different ways to handle errors in React applications.

Identity verification is a crucial step in ensuring someone is who they say they are. This idea is brought through digital identity verification. This reduces the effects of individuals from creating a fraudulent identity, engaging in fraud-related crimes, or acting without the permission of someone else. Organizations must detect the identity of an individual as they manage many prominent security issues like identity theft, data breaches, and fraudulent transactions.

Transportation companies hold together the world’s supply chain. Shipping goods internationally, transporting fuel from refineries, bringing products to retail outlets, and delivering packages last mile to consumers’ homes—transportation is the glue of the economy. This responsibility comes with enormous pressure. These companies are on the hook when deliveries run late due to things like shipping container shortages.

Phoenix LiveView lets you develop full-stack apps with client-side interactions while mostly avoiding cross-stack hassle. Assigns, managed by the LiveView socket, are a core tool for making that happen — allowing you to store, present, and update data effortlessly and efficiently.

Passwords are becoming obsolete, and the tech world is exploring various different technologies to allow users to log in without passwords. In a previous article, we discussed the perils of passwords and how FIDO2 can help us go passwordless. However, FIDO2 is no silver bullet as it comes with its fair share of caveats. Magic link is a viable alternative for all those who do not want to use FIDO2. This article discusses magic link in detail and demonstrates how we can use it with Asgardeo.

Containers are popular because they create a reproducible environment that you can deploy to production and run locally in development. However, containerizing a Rails app can be tricky—Jeff Morhous helps us navigate the pitfalls.

Even if we have a good project plan and a logical concept, we will spend the majority of our time correcting errors. Furthermore, our application can run without obvious errors with JavaScript, we must use various ways to ensure that everything is operating properly. The majority of JavaScript errors in our web applications will be eliminated if we understand both the syntax and how JavaScript works. Furthermore, numerous web services can help us in catching all of them.

To run Java applications optimally, the JVM divides memory into stack and heap memory. Whenever new variables and objects are declared, new methods are called or other similar operations are performed, the JVM designates memory to these operations from either the Stack Memory or Heap Space. Heap space is used for the dynamic memory allocation of Java objects and classes at runtime. New objects are always created in the heap space, and references to these objects are stored in the stack memory.

The claims stage is critical in the insurance customer lifecycle, acting as a moment of truth in the provider’s ability to serve the client as promised. Because it can often be an emotional experience for customers, insurers that value a seamless experience need to prioritize efficient and effective first notice of loss (FNOL) intake.

Picture this scenario: you are a Rails developer and have spent the last couple of days developing that awesome feature that everyone is waiting for. It's big and complex, but it went through rigorous testing, so you are confident everything works as it should. There are deadlines to meet, so you deploy. Immediately, all hell breaks loose. Your feature straight up breaks the entire app for some of your users. It's hard to say why. No bugs showed up during testing.

In our final year as undergraduates, we researched how to use human affect and behaviors to anticipate threats posed by other humans. We built a simple website that demonstrated the capabilities of the model we designed.

Like most modern programming languages, Java includes the concept of exceptions to handle both errors and "exceptional events." When an exception occurs in your code, it disrupts the normal instruction logic and abnormally terminates the process. However, with a little foresight and code, you can often handle these exceptions gracefully, allowing your code to continue running and providing insight for tracking down the root cause of the unexpected result.

Case management can mean a lot of different things, depending on the industry you’re working in. A case could be seeing a patient for a doctor, a legal proceeding for a lawyer, a customer request for a customer service team, an investigation for a corporate management team—we could go on and on.

WordPress is a Content Management System (CMS), which is a tool that optimizes the process of producing, storing, and displaying web material. But you already know that, right? Well, how about this then – did you know that WordPress began as an improvement tool to improve the routine typography of day-to-day writing, but it was later adopted as a blogging tool? When it was first released, WordPress was nothing more than a typographic improvement.

Many API developers and companies struggle to find ways to easily set up systems to monetize their APIs.

ESG expectations come to insurers from a multitude of stakeholders, including customers, employees, board members, and more.

Spring Boot has made the Spring Framework more accessible than it already was. It is a streamlined form of the larger Spring Framework. For one, Spring uses manual configurations while Spring Boot contains a number of default config templates. Spring has a number of dependencies; Spring Boot, not so much (at least until build time). Auto-configuration makes it easy to get started with the Spring Framework (or even Java overall if you’re a true novice to coding) and the support community is huge.
