Hi all! The dev.family team is in touch. In this article, we are sharing a short guide on how to install Splash Screen in a cross-platform app written in React Native with support for multiple themes.Splash screen is the first screen that users see before loading into the main application. This screen is perhaps the best way to make the name of your app, and in general, its entire name,... Read more ›

![[Translation] Application performance monitoring and health metrics without APM](https://times42.com/media/7/7/1/2305771_640x200.jpg "[Translation] Application performance monitoring and health metrics without APM")
I have already written about AIOps and machine learning methods in working with IT incidents, about hybrid umbrella monitoring and various approaches to service management. Now I would like to share a very specific algorithm, how one can quickly get information about functioning conditions of business applications using synthetic monitoring and how to build, on this basis, the health metric of business services at no special cost. The story is... Read more ›

Nowadays a lot of product managers have to confirm most of their decisions with AB-tests. Yet, it is far not always clear how to choose the parameters for the test. A particularly difficult parameter to tune is often the level of statistical significance. If we choose too high level - tests will fail even though improvements do exist. If we choose too low level - we'll be getting lots of... Read more ›

A basic data structure in computer science is the “associative array” known as a “map”. This structure is called a “dictionary”. Dictionaries are being used when you have key-value pairs of the information. Inputs are called keys, and outputs are called values. A dictionary is the abstract data type that can store elements so that they can be positioned quickly by using keys. Dictionary is like a container that will... Read more ›

We continue to develop PVS-Studio as a SAST solution. Thus, one of our major goals is expanding OWASP coverage. You might ask, what's the use when there's no taint analysis? That's exactly what we thought — and decided to implement taint analysis in the C# analyzer. Curious about what we accomplished? Read on! Read more → Read more ›

Angular is one of the most popular front-end development frameworks out there. It is a leading choice for personal as well as industry-level development of web applications due to its robust capabilities. While Angular is popular for many different reasons, one of the main ones is its modular nature. Modularity makes it easy for the developer to keep track of all the different elements being used to program functionalities. It... Read more ›

From the earliest days, we used MSVC to compile the PVS-Studio C++ analyzer for Windows - then, in 2006, known as Viva64, version 1.00. With new releases, the analyzer's C++ core learned to work on Linux and macOS, and we modified the project's structure to support CMake. However, we kept using the MSVC compiler to build the analyzer's version for Windows. Then, in 2019, on April 29th, Visual Studio developers... Read more ›

Data structures are classified into linear and non-linear data structures. A tree is a non-linear data structure. Data is stored hierarchically in a non-linear data structure. So the tree is a way of organizing data hierarchically. A tree grows from top to bottom. In a tree, there are different kinds of nodes that are linked with each other. A tree consists of the following elements: Читать далее Read more ›

It is a collection of edges and vertices. It can be used to display any form of network.The following graph contains a total of 4 vertices and 5 edges. In this graph, vertices are A, B, C and D while edges are AB, BD, DC, CA and AD. Vertices are also known as nodes. The line connecting these vertices is the edge. Vertices are like objects and edges indicate the... Read more ›

Sorting is the process that is used to arrange the elements in a specific manner. A sorting algorithm is used to rearrange a given array according to the specific order. It can sort an array in either ascending or descending order. We need a sorting algorithm because it helps us to easily and fastly locate elements in the array list. The key purpose of sorting algorithms is to get the... Read more ›

Recursion is a strategy that algorithms use to solve specific problems. A recursive algorithm is an algorithm that solves the main problem by using the solution of a simpler sub-problem of the same type. Recursion is a particular way of solving a problem by having a function calling itself repeatedly. It is always applied to a function only. By using recursion, we can reduce the size of the program or... Read more ›

We describe the implementation of a custom Domain Name System (DNS) by using C socket programming for network communication, together with SQLite3 database for the storage of Internet Protocol (IP) for Uniform Resource Locator (URL). Then we provide a performance analysis of our implementation. Our code is available publicly [1]. Read more Read more ›

On implementing streaming algorithms, counting of events often occurs, where an event means something like a packet arrival or a connection establishment. Since the number of events is large, the available memory can become a bottleneck: an ordinary -bit counter allows to take into account no more than events.One way to handle a larger range of values using the same amount of memory would be approximate counting. This article provides... Read more ›

Dynamic programming is applied to solve optimization problems. In optimization, we try to find out the maximum or minimum solution of something. It will find out the optimal solution to any problem if that solution exists. If the solution does not exist, dynamic programming is not able to get the optimal solution.Optimization problems are the ones that require either lowest or highest possible results. We attempt to discover all the... Read more ›

Asymptotic notations are used to represent the complexity or running time of an algorithm. It is a technique of defining the upper and lower limits of the run-time performance of an algorithm. We can analyze the runtime performance of an algorithm with the help of asymptotic notations. Asymptotic notations are also used to describe the approximate running time of an algorithm.Types of Asymptotic NotationsFollowing are the different types of asymptotic... Read more ›

Cегодня мы рассмотрим инфраструктуру управления и контроля (C2), используемую злоумышленниками для управления зараженными устройствами и кражи конфиденциальных данных во время кибератаки. Успешная кибератака — это не просто вторжение в систему ничего не подозревающей об этом организации. Чтобы получить реальную выгоду, злоумышленник должен поддерживать постоянное функционирование вируса в целевой среде, обмениваться данными с зараженными или скомпрометированными устройствами внутри сети и потенциально извл Read more ›

Работа с контейнерами многим кажется волшебством, пришло время разобраться как работает сеть Docker. Мы покажем на примерах, что это совсем не сложно. Нам потребуется немного сетевой магии и никакого кода ...В этой статье мы ответим на следующие вопросы:- Как виртуализировать сетевые ресурсы, чтобы контейнеры думали, что у каждого из них есть выделенный сетевой стек?- Как превратить контейнеры в дружелюбных соседей, не дать им мешать друг другу и научить хорошо общаться?-...
