In microservice world the problem of high load is exteremely big especially when we have a REST API which is accessed quite extensively. Why do we need throttling? The main answer is to decrease the load of the service at the moment. Different frameworks have different solutions, mostly some additional libraries. Also there is a Guava RateLimiter and Bucket4J . What is interesting Spring MVC being one of the most... Read more ›

Here I am going to cover my own approach to compilation of mathematical functions into Linq.Expression. What we are going to have implemented at the end:1. Arithmetical operations, trigonometry, and other numerical functions2. Boolean algebra (logic), less/greater and other operators3. Arbitrary types as the function's input, output, and those intermediateHope it's going to be interesting! Read more → Read more ›

![[Translation] Architecting Architecture](https://times42.com/media/4/8/4/1841484_640x200.jpg "[Translation] Architecting Architecture")
Architect. This word sounds so mysterious. So mysterious that to understand it you almost forced to add something. Like “System Architect” or “Program Architect”. Such addition does not make clearer, but for sure adds weight to the title. Now you know – that’s some serious guy! I prefer to make undoubtful and around 10 year ago added to my email signature “Enterprise Architect of Information Systems”. It’s a powerful perk.... Read more ›

The DHT system has existed for many years now, and torrents along with it, which we successfully use to get any information we want.Together with this system, there are commands to interact with it. There are not many of them, but only two are needed to create a decentralized database: put and get. This is what will be discussed below... Read more ›

Security. What does this word mean to you? Nowadays, companies spare no effort to ensure that their product is secured from hacking and all sorts of information leaks. PVS-Studio decided to help its users and expand the functionality in this area. Therefore, one of the main innovations of the upcoming release will be the introduction of analyzer new features which will ensure code safety and security. This article aims to... Read more ›

We work using Agile: Scrum, or Kanban, or any other extended project management way. Agile appeared in 2001 as a result of a long discussion between really smart guys. They just formed best practices of management into the shape of short documents - the Agile Manifesto. But what did they want to replace by the Agile way? Most of you may say that they wanted the Waterfall to go to... Read more ›

If you work with Azure infrastructure and have to integrate message queues. It sounds quite simple: just create Azure Resource, write some code and then be happy! But what would you say if the resources are limited? What will you do if there are several teammates in your team, and all of you have to debug queues at the same time? I try to give you a simple solution. Read... Read more ›

Most solutions to algorithmic problems can be grouped into a rather small number of patterns. When we start to solve some problem, we need to think about how we would classify them. For example, can we apply "fast and slow" algorithmic pattern or do we need to use "cyclic sort" pattern? Some of the problems have several solutions with different patterns. In this series, we cover the most popular algorithmic... Read more ›

In this article, we discuss the postorder traversal of a binary tree. What does postorder traversal mean? It means that at first, we process the left subtree of the node, then the right subtree of the node, and only after that we process the node itself.Why would we need to do it in this order? This approach solves an entire class of algorithmic problems related to the binary trees. For... Read more ›

Let me also say a word about properties. I'm going to consider a good use of them for immutable records in C#.I am a big fan of code design, so in this article I want to cover existing approaches and show what, I think, is a better solution. ReadMore() → Read more ›

Having only programming background, it is impossible to develop software in some areas. Take the difficulties of medical software development as an example. The same is with music software, which will be discussed in this article. Here you need an advice of subject matter experts. However, it's more expensive for software development. That is why developers sometimes save on code quality. The example of the MuseScore project check, described in... Read more ›

C# capabilities keep expanding from year to year. New features enrich software development. However, their advantages may not always be so obvious. For example, the good old yield. To some developers, especially beginners, it's like magic - inexplicable, but intriguing. This article shows how yield works and what this peculiar word hides. Have fun reading! Read more Read more ›

After 210 days, 600 commits, tens of debugging nights, and thousands of messages in the project chat, I finally released AngouriMath 1.2.This is an open-source symbolic algebra library for C# and F#, maybe it is interesting for someone? Read more Read more ›

In our articles, we regularly repeat an important idea: a static analyzer should be used regularly. This helps detect and cheaply fix many errors at the earliest stage. It looks nice in theory. As we know, actions still speak louder than words. Let's look at some recent bugs in new code of the Blender project. Read more → Read more ›

PVS-Studio is a static analyzer that allows to find many problems hidden in the source code. Among them there are also errors related to application security. For example, the analyzer has recently learned to identify the presence of confidential data such as passwords in the code. The OWASP Top Ten list includes this potential vulnerability. It is much more dangerous than it may seem at first glance. What makes it... Read more ›

Создание чего-то нового — дело всегда рискованное. Как и многие люди до вас, вы пишете бизнес-план, предлагаете его инвесторам (либо роетесь в собственном кошельке), набираете людей, начинаете разрабатывать продукт, тратите тысячи человеко-часов. А потом, спустя месяцы разработки (а иногда и годы) получается, что вы всё это время усиленно делали продукт, который никому не нужен. Вот вообще. А деньги и время уже потратили. Как понять, что ваш продукт не будет успешен,... Read more ›

Такие приложения, как Snapchat, предлагают удивительное разнообразие фильтров для лиц и объективов, которые позволяют накладывать интересные эффекты на фотографии и видео. Если вы когда-либо дарили себе виртуальные собачьи уши или праздничную шляпу, вы знаете, насколько это может быть весело! Задумывались ли вы о возможности создания таких фильтров с нуля? Что ж, теперь у вас есть возможность научиться всему, используя только веб-браузер! В этой серии статей мы узнаем, как создавать в... Read more ›

Techstars Startup Digest was designed as a discovery tool for entrepreneurs looking for tech events in their area. It was founded in 2009 by Chris McCann who just moved to the Valley. He created an old-school newsletter, featuring promising events in the Bay Area. There was no website, all the events were hand-picked by Chris himself, and the newsletter had 22 subscribers. People liked the idea and that number quickly... Read more ›

Have you ever heard of Image File Execution Options (IFEO)? It is a registry key under HKEY_LOCAL_MACHINE that controls things like Global Flags and Mitigation Policies on a per-process basis. One of its features that drew my attention is a mechanism designed to help developers debug multi-process applications. Imagine a scenario where some program creates a child process that crashes immediately. In case you cannot launch this child manually (that... Read more ›

The most popular computer ever sold to-date, the Commodore C-64, sold 27 Million units total back in the 1980’s. Little is left to show of those times, the 8-bit “retro” years when a young long-haired self-taught engineer could, through sheer chance and a fair amount of determination, sit down and design a computer from scratch using a mechanical pencil, a pile of data books, and a lot of paper.
