There is an open project COVID-19 CovidSim Model, written in C++. There is also a PVS-Studio static code analyzer that detects errors very well. One day they met. Embrace the fragility of mathematical modeling algorithms and why you need to make every effort to enhance the code quality. Read more → Read more ›

In PVS-Studio, we often check various compilers' code and post the results in our blog. Decompiler programs, however, seem to be a bit neglected. To restore justice in this world, we analyzed the ILSpy decompiler's source code. Let's take a look at the peculiar things PVS-Studio found. Читать далее Read more ›

There is a myriad of articles about where to find remote jobs, particularly in tech. Some of them are outdated and most of them don't provide detailed reviews. So that's why I decided to do my own research. I did a basic search by "React" skill (where possible) and expected to see mostly "Frontend Developer" vacancies. Read more Read more ›

The compound annual growth rate for Machine Learning stands at a whopping 44.1%, as per Development stats. This means the Machine learning market will reach 8.81 billion USD by 2022. The pragmatic use of ML in image recognition, speech recognition, medical diagnosis, CRMS, etc., has led to startups investing in the technology.The technology can effectively predict a user's behavior based on the acquired data. However, it requires excellent domain knowledge... Read more ›

Speech analytics is the process of analysing recorded speech, such as phone calls, to gather customer information to improve communication and future customer interaction. Speech analytics as a technology has been evolving especially rapidly over the last few years. It gives the ability to structure and analyse previously lost streams of insight-rich data, such as phone conversations. Empowered with this technology, operations can gather incredibly valuable business intelligence to drive... Read more ›

The PVS-Studio analyzer is regularly updated with new diagnostic rules. Curiously enough, diagnostics often detect suspicious code fragments before the end of the work. For example, such a situation may happen while testing on open-source projects. So, let's take a look at one of these interesting finding. Read more Read more ›

In 2013 Canonical tried to crowdfund Ubuntu Edge smartphone. Its main feature could be the ability to use the smartphone as a full-fledged PС. Unfortunatly, the crowdfunding campaign did not accumulate enough money, so a dream of having a universal device remained to be the dream.I've been searching for universality, too, on the software side, not the hardware one. Today I can confidently say I found the necessary combination: Git... Read more ›

Home of this article: https://robotics.snowcron.com/coins/02_head_or_tail.htmThe global objective of these articles is to build a coin classifier, capable of scanning your pocket change and find rare / valuable coins. This is a second article in a series, so let me remind you what happened earlier (https://habr.com/ru/post/538958/). During previous step we got a rather large dataset composed of pairs of images, loaded from an online coins site meshok.ru. Those images were uploaded... Read more ›

Hey everyone! This post was born from a question asked by an IT forum member. The summary of the question looked as follows: There is a set of text files containing routing tables collected from various network devices. Each file represents one device. Device platforms and routing table formats may vary. It is required to analyze a routing path from any device to an arbitrary subnet or host on-demand. Resulting... Read more ›

AngelList is a social network designed to connect startups with investors and vice versa. The founders of it were dissatisfied with how opaque the VC world was, and built a transparent online funding network to increase the amount of available data. This drastically improves the price-setting process, and allows startups to find the best investors for their business. The project began in partnership with just 50 volunteer investors wishing to...

All Prometheus metrics are based on time series - streams of timestamped values belonging to the same metric. Each time series is uniquely identified by its metric name and optional key-value pairs called labels. The metric name specifies some characteristics of the measured system, such as http_requests_total - the total number of received HTTP requests. In practice, you often will be interested in some subset of the values of a... Read more ›

What is distributed tracing? Distributed tracing is a method used to profile and monitor applications, especially those built using a microservices architecture. Distributed tracing helps pinpoint where failures occur and what causes poor performance.Let’s have a look at a simple prototype. A user fetches information about a shipment from `logistic` service. logistic service does some computation and fetches the data from a database. logistic service doesn’t know the actual status...

This is the third part of a series covering the implementation of algorithms in Go. In this article, we discuss the Merge Interval algorithm. Usually, when you start learning algorithms you have to deal with some problems like finding the least common denominator or finding the next Fibonacci number. While these are indeed important problems, it is not something that we solve every day. What I like about the Merge... Read more ›

See more at robotics.snowcron.com This is the first article in a serie dedicated to coins classification.Having countless "dogs vs cats" or "find a pedestrian on the street" classifiers all over the Internet, coins classification doesn't look like a difficult task. At first. Unfortunately, it is degree of magnitude harder - a formidable challenge indeed. You can easily tell heads of tails? Great. Can you figure out if the number is... Read more ›
