Nowadays mobiles are an important part of the business. But a few years back the mobile was considered just a tool used for communication but as technology evolved the mobile also evolved and new features are installed and now the mobile is an essential part of the business. If a business is not equipped with a mobile, then business suffers. That is why organizations ensure that their application and website are mobile-friendly.

If you develop software for an embedded system, you need some kind of system feedback. Debuggers are awesome tools, but when it comes to analyzing dynamic behavior in the field, they cannot be used. For remote debugging, many engineers turn to printf, which can usually be quickly put in place after having a putchar() implemented. This turns out to be an expensive way, in terms of processor clocks and required FLASH memory for the strings.

Nest.js is a scalable and efficient server-side Node.js framework built with TypeScript. Nest.js was created to provide a structural design pattern to the Node.js development world. It was inspired by Angular.js and uses Express.js under the hood. Nest.js is compatible with the majority of Express.js middleware. In this tutorial, I will lead you through building a RESTful API with Nest.js. The tutorial will familiarize you with the fundamental principles and building blocks of Nest.js.

Artificial intelligence has been a hot topic of conversation among agency leaders for some time now, and mass adoption of AI as a valuable marketing tool is already well underway. While brands come up with innovative ways to use AI to meet their strategic business, marketing and sales goals every year, they also learn a lot through trial and error in the process.

Maintaining an endpoint, especially a customer-facing one, requires constant monitoring, whether using REST or GraphQL. As the industry has looked for solutions to build a more adaptive endpoint technology, it is also a must to monitor these endpoints. GraphQL and REST are two different technologies that allow user-facing clients to link to databases and platform logic. Both GraphQL and REST include monitoring techniques.

The Internet of Things (IoT) market is evolving at a rapid pace and while some of the early predictions for tens of billions of connected devices by 2022 have proved to be wide of the mark, the use cases are so varied that explosive adoption is likely. However, the encroachment of IoT into all aspects of our personal and business lives brings with it plenty of concerns, from security and data ownership, to business models that acknowledge and enable the global nature of connected devices.

gRPC is a remote procedure call framework that has been widely adopted among cloud native applications. It is an attractive choice for engineers needing more capabilities than what REST APIs provide. However, observability and testing tools for gRPC are few and far between. Because of this, triaging or understanding application behavior is potentially time-consuming and overly burdensome.
