Why should you be grateful for act() warnings in React tests

If you have ever written a test using the React Testing Library there is a good chance you have encountered the notorious act() warning. Usually, a solution can be found through intuition and/or a lucky guess, but not this time, though. Welcome! Let’s dive deeper into act() warnings to really understand them. I have created an uncomplicated newsletter app to act as a simple example.

MVP Strategy & Implementation for Network Applications

A minimum viable product (MVP) is a great solution for testing product viability. However, sometimes an MVP misses its mark, and there is little clue as to why it happened. One of the reasons for failure can be using the wrong MVP strategy. Read on to find out what you need to know before minimum viable product implementation and how to plan a minimum viable product properly. The main reason to invest in a minimum viable product is that an MVP helps save time and money. How? A minimum viable product is cheaper than trying to launch a full-fledged product all at once.

Network ACL processing algorithms — optimizing firewall's performance

A firewall is an important component in protecting a network from attacks. It allows configuration of what kind of traffic is allowed inside the network. So in a sense, a firewall is a barrier that can reject all suspicious connections at the very entrance to the network, making potential attacks significantly more difficult. There are many types of firewalls. In this article, we will focus only on simple stateless firewalls that work in the 3rd and 4th layer of the OSI model (L3 + L4 firewalls). Typically, a firewall uses a user-specified access control list (ACL) to decide which packets to let through and which to block.

Software-Defined Networking (SDN) — a gentle introduction

The SDN approach to network architecture has been steadily gaining ground. More and more companies are designing their network infrastructure with this approach in mind. According to Statista, the traffic from SDNs and virtualized network functions in data centers from around the world in 2021 was estimated to have achieved 7.4 zettabytes. The increasing popularity of software-defined networking across a variety of industries shows how important this technology has become for global businesses. This article provides you with the classic definition of software-defined networking technology, then covers a few typical use cases and explains why software-defined networking technology is worth your time.

MVP vs. prototype — which one do you need?

If you build software, for sure you know that you need to pass through several stages before launching the final product. Choosing the right development technique is one of the most important decisions to make, and the way you validate your business idea is another. Product validation sets your software up for success by challenging assumptions, revealing market demand, and defining explicit direction for product growth. IT businesses commonly use a prototype and a minimum viable product to verify whether their business concept will be embraced by target users and stakeholders.

What is Python used for?

Nowadays, it is almost impossible not to have heard about the Python programming language. There are numerous sources that describe this technology, but sometimes, one piece of information is missing. What actually is Python used for? In what types of projects does Python work the best? Sometimes there are so many questions and so few answers. This article aims to dispel any doubts and show Python’s possibilities. To start with, it is worth mentioning that this article focuses on the classic Python implementation (CPython).

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?
