Hello, Habr! In this article, I want to tell you about a wonderful tool for developing batch data processing workflows, for example in corporate DWH infrastructure or your DataLake. We'll talk about Apache Airflow (hereafter Airflow). It has been unjustly neglected on Habr, and in the main part, I will try to convince you that Airflow is at least worth considering...
Preface: By fate, I transitioned from the world of academic science (medicine) to the world of information technology, where I have to use my knowledge of experimental design methodology and data analysis strategies, while applying a new technology stack. During the process of mastering these technologies, I face a number of challenges that, fortunately, I am currently managing to overcome. Perhaps this post...

With Docker, you can separate your application from your infrastructure and […]
Hello everyone. This is Sergey Omelnitsky. Not long ago, I hosted a stream on reactive programming where I talked about asynchronicity in JavaScript. Today, I would like to summarize this material. But before we dive into the main content, we need to start with an introduction. So, let's begin with definitions: what is a stack and a queue? A stack is a collection where elements […]
A vulnerability (CVE-2019-9848) has been identified in the LibreOffice office suite, which can be exploited to execute arbitrary code when opening documents prepared by an attacker. The vulnerability is caused by the LibreLogo component, which is intended for programming education and inserting vector graphics, translating its operations into code in the Python language. By executing LibreLogo instructions, an attacker can achieve code execution in Python […]
Starting in 2020, Google will introduce a new search engine selection screen for all Android users in the EU during the initial setup of a new phone or tablet. The chosen search engine will become the default in Android and the Chrome browser, if installed. Search engine owners will have to pay Google for the right to appear on the selection screen alongside Google search. The three winners […]
On Friday, August 2nd, the release of re2c was announced — a free lexical analyzer generator for C and C++ languages. It should be noted that re2c was written in 1993 by Peter Baeumer as an experimental generator of very fast lexical analyzers, distinguished from other generators by the speed of the generated code and an unusually flexible user interface, which allows for easy and efficient embedding of analyzers into existing […]

Digital transformation is a serious challenge. What should the program for transforming IT systems to achieve business digital transformation be based on? The right IT infrastructure is the key to […]
