Today we continue the story of how we, together with the guys from Innopolis University, are developing the Active Restore technology to allow users to start working on their machines as soon as possible after a crash. We'll discuss native Windows applications, including the specifics of their creation and launch. Below — a bit about our project, as well as a practical guide on how to write […]
Magic constants C — Cleanliness (see Marshak), B — Balance (see Nash), MLP — Materials, people, and process in space (see Mayakovsky, Corbusier). A fresh graph-based convolutional neural network can even be useful in the kitchen. It's easier than ever to start playing molecular cuisine. It is enough to describe a dish as: $inline$H = sigma [ hat D ^{-½} hat […
If at the beginning of the play you mention a C++ code on the wall, by the end, it should definitely shoot you in the foot. Bjarne Stroustrup From October 31st to November 1st, the C++ Russia Piter conference took place in St. Petersburg – one of the largest programming conferences in Russia, organized by JUG Ru Group.

Some time ago, 'My Circle' participated in a discussion organized by our friends from Index School, focusing on the employment of novice specialists. The organizers presented the participants with the following problem: "The IT industry has long been in need of professionals, and this is no news to anyone. It seems that the solution to the problem should come from the abundance of novice specialists available in the market. […
Another release has taken place in the current mainline branch of the nginx web server.

I completed my first year of study in the Online Master of Science in Computer Science (OMSCS) program at the Georgia Institute of Technology (3 out of 10 courses). I wanted to share some interim conclusions. You shouldn't go there if: 1. You want to learn programming. In my understanding, a good programmer should: Know the structure of a specific language, standard libraries, etc.; Be able to […]
Part One: Basics of Working with Video and Images What? A video codec is a part of software/hardware that compresses and/or decompresses digital video. Why? Despite certain limitations in bandwidth and storage capacity, the market demands increasingly higher quality video. Do you remember how in the last post we calculated the minimum required for 30 […]
Part Two: Principles of How a Video Codec Works Any raster image can be represented as a two-dimensional matrix. When it comes to colors, the idea can be expanded by considering the image as a three-dimensional matrix, where additional dimensions are used to store data for each of the colors. If we look at the final color as a combination of so-called primary colors (red, green, and blue), in our […]
The release of the Python library for scientific computing, NumPy 1.18, has occurred. It is designed for working with multidimensional arrays and matrices while providing a large collection of functions implementing various algorithms related to matrix usage. NumPy is one of the most in-demand libraries used for scientific calculations. The project code is written in Python with optimizations in C and is distributed […]
