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?-...

Делимся результатами небольшого исследования, которое Хабр Карьера помогла провести коллегам из OTUS Онлайн-образование. Вместе мы изучили, как пандемия повлияла на работу в ИТ: что изменилось в процессе найма, какие плюсы и минусы находят айтишники в удалённом формате работы. В этом исследовании приняли участие 60 компаний и 350 ИТ-специалистов. В конце статьи мы дали несколько советов, на что стоит обратить внимание при поиске работы в этом году. Читать далее Read more ›

In this topic, I will tell you how to dynamically parse and deserialize only part of the whole JSON document. We will create an implementation for .NET Core with C# as a language.For example, we have the next JSON as a data source for the report. Notice that we will get this JSON in the runtime and at the compile step we don't know the structure of this document. And... Read more ›

A graph is a kind of data structure that includes a set of vertices and edges. Graph traversing means a visit to each vertex of the graph precisely. The graph traversing is used to determine the order in which vertices are being visited throughout the search process. A graph traversing searches for the edges that will be used in the search operation without establishing loops. This means that using graph... Read more ›

Hi, My name is Alex and I am a DevOps engineer at Altenar. “No Windows, no problems.” - that is the answer I got by asking a guru of Ansible "How do you manage Windows?" on one of the local Ansible meetups. Although we have been running a modern stack (k8s, helm, .net core, etc) in production for about two years, that’s not how it has always been. Read more Read more ›

Stack Stack is a linear data structure. In stack, data access is limited. It follows the rule of insertion and deletion of data. Stack is a collection of only similar data types. Elements in the stack are arranged sequentially. It follows the LIFO principle which is the last-in and first-out rule. ExampleTo understand this concept, let us take an example of arranging coins. If we start placing coins one after... Read more ›
