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.

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:
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.
IPTV is quickly rising to the top of the list of TV viewing options for viewers worldwide. other types of home entertainment, including music and video. This indicates a developing market for service providers and a potential new source of income. But how can you set up an IPTV service? Mware Solutions can assist you in establishing the required infrastructure for a successful entry into this cutthroat market.
TV delivered using an Internet Protocol Network is known as IPTV. This new technology has the potential to alter how we watch television at home, get training, utilize computers, and even use cell phones. From computer monitors and mobile phone screens to plasma and LCD televisions, it is used to provide television services to all of these devices. But how can you launch an IPTV company and become a provider of IPTV? An IPTV business solution is what?
We, therefore, decided to offer an eight-week boot camp to teach you everything you require to launch your own IPTV company. You may build the necessary infrastructure with the aid of Setplex to successfully enter this cutthroat market.
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.

The sound of rock music, in particular of hard rock and heavy metal, is largely based on a specially distorted guitar sound, for which electronic “distortion” devices, tube amplifiers in “overloaded” mode, computers with appropriate software and digital processors are used. increasingly using neural network algorithms.
The distorted sound of electric guitars began to gain popularity around the 1960s. Since that time, the sound of overloaded tube amplifiers, connected to powerful dedicated guitar speakers with large dedicated speakers, has been considered the benchmark in rock music. But tube amplifiers were relatively expensive and inconvenient to operate. Therefore, semiconductor distortion devices were developed.
At that time, the electrical circuitry of distortion devices was relatively simple and the signal output from their output only vaguely resembled the sound of an overloaded tube amplifier. Nevertheless, it was still somewhat similar to the “sound of a lamp” and this provided a powerful incentive for designers of analog semiconductor distortion circuits to continue their research, complicate circuits and propose new circuit solutions. The heyday of analog solid-state distortion was around 1995-2010. The most popular were electrical circuit diagrams like those shown in the figure below.

Apple next year is planning to enter a new product category, launching its first mixed reality headset. Rumors indicate that the upcoming headset will support both AR and VR technology, and that it will have features that will outshine competing products.
With the iPhone, iPad, and Apple Watch, Apple's hardware and software led it to dominate those categories within a few short years after entering a new market, and it's likely the same thing will happen with augmented and virtual reality. We've rounded up 10 features rumored for the AR/VR headset that will set it apart from competitors.
How we listened to the needs of our customers and implemented the feature with the maximum capabilities of the iOS and Android platforms. Then we looked into analytics, added onboarding, and usage grew. At the end of the article there are some cool conclusions and insights. Developing a video conferencing mobile app is fun!
So far we've discussed query execution stages, statistics, and the two basic data access methods: Sequential scan and Index scan.
The next item on the list is join methods. This article will remind you what logical join types are out there, and then discuss one of three physical join methods, the Nested loop join. Additionally, we will check out the row memoization feature introduced in PostgreSQL 14.
The common combination of JUnit5, Selenide and Allure has proven to be stable and reliable for autotesting. The remaining issue, however, lies in test length increase up until the rise of overall test numbers. The resulting video files turn out to be over an hour. Alexander Kochergin, Lead engineer at Innotech, has found a way to simplify the process.
