Product-market fit — what is it and how to achieve it?

Are you wondering if your product will succeed on the market? Many business owners are asking themselves the same question. Trying to build growth in the wrong market or with a product that your customers don't need can be difficult or even impossible to achieve. That's why before you start "growing" it's a good idea to check if your product or service has a good product-market fit. Finding product-market fit can highly benefit your company. It can contribute to growth potential, increased sales, and overall performance.

Linux network troubleshooting — commands and examples

Linux is a popular and powerful operating system that is widely used in both personal and professional settings. One of the key features of Linux is its robust networking capabilities, which make it an excellent choice for a wide range of networking tasks. The Linux network stack has grown significantly throughout the years and currently supports not only basic functionalities but also advanced and complex features (e.g. network namespaces allowing the creation of different and isolated network stack instances).

Esthetic or functional? The essence of product design for network applications [interview]

According to a PLA report, more than 50% of respondents claim that UX for analytics is crucial. It is even more true regarding modern network solutions that require a clear visualization of massive amounts of data that can be utilized by users. Nevertheless, manycompanies still avoid investing their time and money in user experience. Why is that? For the answers to these and more questions, we talked to Sebastian Janiec, a product designer at CodiLime. Read further to learn more about Sebastian’s experience in product design for complex network solutions and his views on creating user experience for networks.

Traditional Internet vs. SCION Architecture

Almost everyone knows and uses the Internet but almost nobody knows about its most modern and secure architecture- it's called SCION (SCALABILITY, CONTROL, AND ISOLATION ON NEXT-GENERATION NETWORKS). Read this blog article to learn more about it and how it compares to traditional internet architecture. The Internet is a world-wide global system of interconnected computer networks. Using the Internet, we can share data and information across the globe instantly. The Internet has made the world a smaller place to live in.

Manual testing vs. automated testing — main differences

The need for rapid development and competitive time to market means companies are looking for time-saving solutions at every stage of development, including testing. This has resulted in the emergence of new tools that automate the testing process and make it more efficient. But will automated testing ever fully replace manual testing? Let’s take a look at both kinds of tests, when to use them, and their main differences. Let’s start with the original method of testing, the manual one. Before any product reaches the market, it needs to be thoroughly checked - whether it’s safe, functional, and easy to use.

Best practices for microservices you should adopt

Microservices are all the rage these days. But the simple fact of implementing microservices architecture on your project doesn’t guarantee success. There are certain recommended practices that you should follow when it comes to microservices. Only then can you be sure that you will unlock the full potential of microservices architecture. Before learning in-depth about what you should keep in mind when adopting microservices, let’s quickly recap what they actually are. Microservices architecture presupposes building an application as a bunch of loosely coupled independent components.

DevOps lifecycle: everything you need to know

DevOps is transforming how software is built and deployed by offering a more collaborative working environment and bridging the gaps between development, operations, and quality assurance. However, to fully profit from all the advantages that DevOps has to offer, it is recommended to adopt the complete DevOps lifecycle process. In this article, we’ll explain the DevOps lifecycle, its phases, and the tools used to build software. DevOps is a widely used methodology and is already well-known in the IT industry.

Angular component state management — how to do it with RxAngular and NgRx

State management is already a well-established concept in programming but that does not mean it’s a done deal. Widely used in commercial applications, the concept is still evolving and new ideas are still being developed. In this article, I’m going to focus on web applications built with Angular, however some concepts may be similar and applicable to other frontend frameworks for software development. Let’s begin with a quick reminder about the evolution of state handling in web apps. Around 2015, when the Redux concept was introduced, the only state was the global state app.

Introduction to network telemetry

You may have already heard about network telemetry, but you are not sure you understand well enough what exactly is behind it. If that's the case, you'll find the right explanation in this article. The term "network telemetry" can be understood in different ways. Over the years, it was not completely clear for everyone. Following the RFC 9232, you will come across the following understanding of the terms "network telemetry" and "telemetry data"- “Network telemetry is a technology for gaining network insight and facilitating efficient and automated network management.

FD.io’s VPP’s mechanical sympathy – thread and memory management techniques explained

We've previously explained how VPP processes packets in vectors as opposed to processing each packet end to end. But how is this processing spread across CPU cores? How exactly is a vector of packets structured?
