Development

In order not to buy a defective monitor, it is highly recommended to check it before buying. DE10-Lite is great for this because of a compact size and the presence of a VGA connector.

We are the first year students studying Computer Science in Innopolis University and we would like to share our experience in developing a Verilog program to create the greatest Memory Game (MemGame) that has ever existed on the FPGA board.

In this article, we decided to create a game for extending human memory. You will read the background theory and the incredible story of creation.

The goal of paper is to demonstrate non-trivial approaches to give statistical estimate for forecast result. Idea comes from probability cone concept. A probability cone is an indicator that forecasts a statistical distribution from a set point in time into the future. This acticle provide alternative approaches using machine learning, regression analysis.

During the last years, one of the modern directions of technology development is computer vision. The main task of this direction is the classification of objects from a photo or video camera. In usual problems, it is solved using case-based machine learning methods. This work presents the application of computer vision for traffic sign recognition using machine learning algorithm. A road sign is a flat artificial object with a fixed appearance. There are two applied problems in which road sign recognition algorithms are used. The first task is to control an autonomous vehicle. Self-driving cars are cars that can drive on roads without a driver. A key component of an unmanned vehicle control system is object recognition. Objects of interest are primarily pedestrians, other vehicles, traffic lights and road signs.

Traffic signs are a fundamental portion of our day to day lives. They contain critical information that ensures the safety of all the people around us. A road sign is a flat artificial object with a fixed appearance. There are two applied problems in which road sign recognition algorithms are used. The first task is to control an autonomous vehicle. Self-driving cars are cars that can drive on roads without a driver. A key component of an unmanned vehicle control system is object recognition. Objects of interest are primarily pedestrians, other vehicles, traffic lights and road signs. The second task that uses traffic sign recognition is automatic mapping based on data from DVRs installed on cars. The task is relevant, because currently, compiling and maintaining detailed roadmaps requires either significant financial costs or a large amount of human time.

Let’s say you want to send an encrypted message to your friend in order to avoid it being intercepted and read by a third party. You generate a random secret key and encrypt the message with it. Let’s say you use AES. But how do you let your friend know the key to decrypt it?

In this article, we will explore how the Elliptic-Curve Diffie-Hellman algorithm works under the hood. The article includes the implementation of this algorithm from scratch, written in Python.

Games can give positive emotions and provide relaxation to a person. However, the main purpose of my project is to get a better understanding of the Verilog language. In addition, coding a game into FPGA will help to define the bounds of this programming language.

The following text consists of two logically connected parts. The first part constructively rules out the assumption that untraceability supposes anonymity. The second part enumerates specific practical tasks in the form of various scenarios when digital signatures (DS) do not provide correct solutions to the task. It is demonstrated that a complete solution can be obtained through a special combination of DS and an interactive anonymous identification protocol.

The e-commerce market in 2022 leaves entrepreneurs no choice but immediately incorporate new technologies. Today it is not enough to follow the latest trends, because you need to be two steps ahead. How to do it?

Consumer behavior has changed, especially since this pandemic. You get used to good things quickly, so online shopping and fast delivery services made us all appreciate our time and comfort.

You have to pay for everything in this life, so retailers and marketplaces have to pay for the growth of demand and profits in the field of e-commerce by regularly introducing new technologies, fighting for consumer loyalty, and rivalry in endless competition.

Here are a few of the latest e-commerce trends that cannot be missed if you want to achieve stable profits and customer growth.

All attention to CRO

Design system creation and integration is a challenging and rather tedious task. It can simply the development process or make it even harder. Anton Polyakov, Project Management Director for Innotech’s Mobile Development Department shares his team’s experience to demonstrate the unforeseen challenges they encountered.

Rust's type system is quite powerful as it allows to encode complex relationships between user-defined types using recursive rules that are automatically applied by the compiler. Idea behind this post is to use some of those rules to encode properties of our domain. Here we take a look at Peano axioms defined for natural numbers and try to derive some of them using traits, trait bounds and recursive impl blocks. We want to make the compiler work for us by verifying facts about our domain, so that we could invoke the compiler to check whether a particular statement holds or not. Our end goal is to encode natural numbers as types and their relationships as traits such that only valid relationships would compile. (e.g. in case we define types for 1 and 3 and relationship of less than, 1 < 3 should compile but 3 < 1 shouldn't, that all would be encoded using Rust's language syntax of course)

Let's define some natural numbers on the type level first.

Augmented reality (AR) has been gaining popularity in recent years, with companies such as Apple, Meta, Google and Microsoft investing heavily in the technology. AR technology allows users to see digital objects and information overlaid onto the real world. This technology has the potential to revolutionize multiple sectors in the future, from healthcare to education to entertainment. In this article, we will explore how AR is going to change these sectors and the potential impact it will have on society. 

We will have a closer look into three sectors and try to see how AR could change them in upcoming future.

InvokeAI 2.2 is now available to everyone. This update brings in exciting features, like UI Outpainting, Embedding Management and more. See highlighted updates below, or the full release notes for everything included in the release.

Imagine this: you are an ordinary frontend developer. When you open your mailbox you found a message — tomorrow DevOps team will make an optimization with Kubernetes. You are experienced developer and you know that environment operation test might go sideways. Test environment is crucial for your job as frontend developer and you don’t want to miss a whole day on a job, so there are two possible solutions present:

1. Setup all microservices on your laptop
2. Prepare mocks for API

I will describe how to mock REST API request via Yakbak.

You can encounter integer sequences all around combinatorics, number theory, and recreational mathematics. And if there is a multitude of objects of the similar form, then one can create an index for these objects. The On-Line Encyclopedia of Integer Sequences, OEIS, is such an index.

This is a translation of my article The On-Line Encyclopedia of Integer Sequences in 2021, published in Mat. Pros. Ser. 3 28, 199–212 (2021).

This article covers the On-Line Encyclopedia inclusion criteria, its editorial process, its role in mathematics, and its future.

Hello! My name is Mikhail Emelyanov, I am embedded software engineer, and I was inspired to write this little roadmap on the capabilities of Python language by a certain commonality among the existing Python tutorials found on the web.

The usual suggestions to study, say, “Algorithms and Data Structures” or “Databases” are especially jarring. You can spend years studying these topics, and even after decades you'd still be able to find something you didn't know yet even without ever venturing outside the scope of Algorithms!

Using video game analogies, we can say that novice programmers often stand on the shore of the lake of boiling lava with an island with the ever-coveted jobs in the center, while the islands in between, which you have to jump on, gradually increasing your skills in successive mini-quests, are either missing, or arranged haphazardly, or their fairly smooth sequence breaks off, never having managed to get you any farther from the shore. Let's try to build a path of hint islands, a number of which, although not without effort, will finally allow us to reach our goal.

For iOS developers, WWDC is always something of a New Year. We are presented with so many new products, and sometimes you can get lost in them. Most of my colleagues are trying to be in touch by watching “Platform State of Union” and all “What’s new” sessions. The event basically provides an opportunity to developers a glimpse of the features to expect from the software part. When Apple has a conference like this one, they want to make sure they have enough time to get everything done. In order to do this, they need to be able to work at their own pace and not worry about how long it will take them to get something done.

This means that if you have a small project, it may not be that important but once you move into larger projects with more people involved, every second saved can be worth several dollars in terms of money saved or profit made by the company. The platform tightly integrates programming languages, frameworks, and tools. Everyone gains when these three complement one another. Customers receive a consistent experience, such as scrolling that feels right every time. And developers may devote more time and attention to what distinguishes the app.

And it’s fine, you don’t need to spend so much time for this other unpopular stuff. However, in these, not-so-popular videos as couple of them may be called as “hidden gems” because of the content or a beautiful presentation/structure. Let me show couple of them!

Hi everyone! My name is Dmitrii Konstantinov and this is a personal story of experience and growth in a cozy startup. How we made a business pivot and adapted the server and mobile apps for it. What challenges did we face and how did we solve them.

In 2021, we were contacted by an industrial plant that was faced with the need to create a system for analyzing processes in its production. The enterprise team studied ready-made solutions, but none of the analytics system designs fully covered the required functionality. So they turned to us with a request to develop their own analytical system that would collect data from all machines and allow it to be analyzed to see bottlenecks in production. For this project, we created a data-driven UI/UX design and also developed a web-based interface for the equipment monitoring system.

Software message brokers became the standard for creating complex systems. However not all IT specialists understand how these instruments work. Pavel Malygin, Lead System Analyst at Innotech, dives into the topic of message brokers and explains how they are used.
