Once upon a time, there was a unity game programmer called Lancelot. A very passionate one, I would say. He didn't know yet, but eventually he would face the darkest side of Unity garbage collection.


Lancelot was always looking for bigger and bigger titles to work on. And so he worked hard to get his big chance in the games industry.

It was not easy, that he knew.

There are quite a few reviews and videos on the Internet about building smart houses. There is an opinion that all this is quite expensive and troublesome in the organization, that is, in general, the fate of geeks. But progress is not standing still. Devices are becoming cheaper and more functional, and design and installation are quite simple. However, the reviews mainly focus on 1-2 examples of use, practically not covering nuances and not creating a complete picture. Therefore, in this article I want to make an overview of the finished project, demonstrate the use cases and pitfalls encountered in building a smart home with Xiaomi devices on the example of a sauna. The described ideas with small variations can also be applied to the automation of the apartment.

Background or why all of this is necessary

For starters, a little background so that the context can be understood. In the early autumn of 2018, the sauna was finished and put into operation. The sauna is an autonomous capital structure with year-round heating and water supply.

Which is the best programming technology for web app development in the year 2020? This is one of the most debated questions among web programmers, students and companies (wanted to develop their own website). Actually, every language has its own pros, cons or advantages, disadvantages. It totally depends on your requirements for website development.

In this blog post, I am going to clear your many doubts related to these programming languages or technologies, so that you can choose the best language according to your specific needs and requirements. Here, I’ll do a detailed and comprehensive comparison between these three most popular programming technologies viz. PHP vs Python vs Ruby (RoR). The comparison is on the basis of various stats and data on different parameters. So, let’s start the battle of most popular programming languages ie: PHP vs Python vs Ruby (RoR).

Millions of businesses exchange information on the internet and to interact with their target audience. This helps them make fast and secure transactions over the web. However, business goals can be achieved when the businesses are able to store all this data for the means of presenting quality output to the end users.

Simply put, in the development industry a web application (or “web app”) is more like a program that uses a web browser to handle the storage and retrieval of the information to present information to the users. This allows a user to interact with the company using the online forms, e-shopping carts, CMS, etc. Some more examples of web applications are online banking, online polls, online forums, online reservations, shopping cart, and interactive games.

Learning about web development is kind of like having too many things on a plate. This blog serves as a way to get your acquainted with the world of web app development.

PHP evolves continuously and they just released their latest PHP 7.4 update. Performance and speed keep advancing, as we have already been proved in the past PHP 7 releases. Preloading is one of the most thrilling new updates. It quickens script execution and makes code cleaner and faster due to the simplified common lines of code.

PHP is an important element in the world wide web and is used in over 79% of all websites. Well-known websites like Facebook, Wikipedia, WordPress and much more are using PHP.
We can see a double speed increase when looking at WordPress sites running PHP and comparing PHP 5 and 7. While using the latest PHP version out there — WordPress powered websites gain the most.

Even most of the experienced Ruby on Rails developers sometimes forgot about annoying mistakes they produce in the long development processes, like n+1 queries or lose a lot of time with some unexpected queries from nowhere.

Not all these mistakes can be avoided before the production, but at least you can try :)

Yes, that’s another list of forgotten or not so popular gems for the better development processes.
Let’s begin.

Are you a business owner looking for PHP web development services or ASP.Net development services, but unable to decide the right technology for your project? Are you looking for the pros and cons of ASP.Net and PHP to take an effective decision?  I have tried to make this task easy for you by comparing ASP.Net and PHP in a very simple way.

There are a number of articles and blogs available over the Internet with a large amount of information about PHP Vs ASP.NET. Unfortunately, most of these blog posts are biased and typically based on promoting one over the other.  

In this blog post, I have done an unbiased comparison between the two most popular technologies i.e. PHP and ASP.NET in today’s world. 

On one side, we have PHP, the world’s most used and popular technology on the internet with billions of dedicated PHP developers across the world. On the other side, we have ASP.NET, a Microsoft platform. Sometimes, it becomes quite difficult to have a clear decision about which technology (Php or Asp.net) should we prefer for our application or website development project? 

Here is an elaborative comparison guide that helps you figure out the best technology for your next web app development project. I can assure you that after reading this article, you’ll have a clear idea about which technology suits you better. Moreover, you can share your thoughts and feedback in our comment box. We welcome your positive feedback for appreciating our work. Also, I will be happy to hear from you if you want us to do some improvements to my article.    

From Netflix to Amazon, Twitter, and many software giants, everyone has started adopting the all-new architectural pattern for software development — microservices. Microservices is an architectural pattern for software development that is a collection of small autonomous units, built around business units.

Warning

First, all the objects and theories described in this article have the status of hypothetical at the moment. That is, the holographic hypothesis and string theories have not been experimentally confirmed many.

Second, a fundamentally new type of mechanical gyroscope with six degrees of freedom is proposed for experimental verification (base) of hypotheses. Of the two and three degrees of freedom mechanical gyroscopes known to science, this is the last of the possible types with the maximum number of degrees of freedom in the holonomic system (GYRO_6DoF).

Third, with the advent of the experimental base — the tops of the physical pyramid, string theories, and the holographic hypothesis, which is actually the foundation of the future Theory of Everything, are temporarily removed from criticism until the moment of practical implementation of the experiment and measurements.

Abstract

Even people far from physics know that the maximum possible data transmission rate of any signal is equal to the speed of light in a vacuum. It is denoted by the letter «c», and this is about 300 thousand kilometers per second. The speed of light in a vacuum is one of the fundamental physical constants. The impossibility of achieving speeds exceeding the speed of light in three-dimensional space is a deduction from Einstein's Special Theory of Relativity (SRT). Usually, when it is argued that SRT prohibits the transmission of the information above the speed of light, an implicit assumption is made that there is no other way other than to «bind information» to a photon and transmit it. However, there is another way. The well-known physical hypothesis — the Holographic Principle (a modern and widely used tool in theoretical physics) points to an interesting phenomenon: “Phenomena taking place in three-dimensional space can be projected onto a remote screen without losing information” — Leonard Susskind “The World as a Hologram ”[p. 3].

Over some time in different jobs, I came across a need for several utilities that I couldn't find available at the time. And I saw that I needed them several times over and over again. So I wrote my own small library that I found very useful. So I just published it as an open-source java library.

Here is the Github link

Javadoc online is available here

Also, this library is available on Maven Central. Here are the Maven artifacts (the version 1.5.1.2 is the latest at the time of writing of this article but might change in the future. To check for the latest version search for artifact «MgntUtils» at http://search.maven.org/):

<dependency>
     <groupId>com.github.michaelgantman</groupId>
     <artifactId>MgntUtils</artifactId>
     <version>1.5.1.2</version>

     <artifactId>MgntUtils</artifactId>
     <version>1.5.1.2</version>
     <classifier>sources</classifier>
</dependency>

Below is just a short explanation of what is there. The library comes with a nicely written (I hope) JavaDoc with a detailed description. So here is the list of features:

The goal of this quick reference is to collect in one place and organize information about value categories in C++, assignment, parameter passing and returning from functions. I tried to make this quick reference convenient to quickly compare and select one of solutions possible, this is why I made several tables here.

Artificial Intelligence refers to the theory of computer systems or human-made robots programmed with performing tasks as humans, such as learning, generalization, and reasoning. With this ability, AI has become a significant part of human lives. Similarly, AI and the education & tutoring web solutions are inseparable from being observed by the astounding inventions enabling machines to mimic human roles.

“Instead of using technology to automate processes, think about using technology to enhance human interaction.” ~ Tony Zambito, Lead authority in Buyer Personas.

Do you know ~ according to research, 93% of customers make purchase decisions based on visual appearance. Visual elements of your brand are the key deciding factors for a majority of potential customers.

Your logo, website colors, chatbot texts, etc all have an impact on the psychology of people who come across them. Some colors or features attract them and some make them leave your website instantly.

In this era, interactive features with the help of technologies like Artificial intelligence are enhancing such effects. AI has the power to add interactive elements to your presentation. This creates a connection between your company and its customers.

Hi there!

The latest years Powershell started expansion to other platforms and now works on Windows, Linux, and MacOS (I even managed to start it on raspberry Pi Debian distro).

And nowadays the main way for installing modules is PowerShell Gallery but in some situations, it still convenient to install modules directly from the source (the main reason — the main PowerShell modules repo configured to MyGet or NugetServer).

And it can be painful to install Module from GitHub — you should download archive, find modules folder extract archive content and then copy module folder to the Powershell Profile directory.

Moreover — people like me don't want to create a separate repository for each module (yes, I like the Release-Flow approach) so download and extract only the modules you are like -it even more difficult.

Are you ready to get started with 3D printing but just aren’t sure about what filament you’re using? You’re definitely not alone because with the multitude of different filaments out there it can really get complicated. You find yourself overwhelmed while you’re trying to research because it seems like everyone has a different idea of what the best option is and it can easily seem like you’re being pulled in different directions. So, let’s take a closer look at how you can make the right decision.

In June, we heard about SwiftUI for the first time — a totally new way of creating and working with UI elements in iOS and macOS (also iPadOS) apps. It felt like Christmas in the summer. It's new, it's declarative, it's sexy! And now, just a few weeks after iOS 13 has been released, we can start to use SwiftUI in all our projects. Let's learn how to use this amazing tool that Apple gave us, to create the classic Tinder-esque Swipe Cards.

In this article, I would like to show you how to achieve a Tinder-like card view and behavior (swipe to action), with just a few lines of code.

To achieve this, we need to do the following things, in order:

• Create UserView
• Create NavigationView
• Create BottomBarView
• Create SwipeView
• Put all this together inside ContentView

So let's get started.

Bill of Materials

Hello everyone!

Today I'm going to tell about how is test task to job interview became the library Image Comparison. It's an open-source library, which is hosting on GitHub.



Before I start, let me introduce myself. My name is Roman. I'm a husband and father. I'm a software engineer in Epam Systems with 4 years of experience in IT.

The main idea of this topic is to tell, that creating an open-source product it's not wasting time, no! It's an amazing experience, which is going from all the open-source community. It's a time when you're a developer, project manager, product manager in one head.

While this library is growing I have been working with people from more than 10(!!) countries, such as the USA, Germany, Chine, India, Russia, Ukraine, etc.

Let's move on from the start of this story…

Vue.js is a JavaScript library for building web interfaces. Combining with some other tools It also becomes a “framework”. Now, from our last blog, you already know that Vue.js is one of the top JavaScript frameworks and it is replacing Angular and React in many cases. This brings in the topic of this blog ‘Vue.js is good, but is it better than Angular or React?


In case you’ve never heard or used Vue.js before, you are probably thinking: Come on! yet another JavaScript framework! We get it. However, Vue.js is not new in the custom software development domain. It was first released in 2013 and now it has 130549 stars on Github and downloaded a number of times this year.

The web development arena is moving at a fast pace and has reached an advanced stage today. Python and Javascript making some significant contributions for almost three decades. Now, being a developer or a business if you are planning to pick one of these, then it’s going to be tough just because both are too good to avoid. Hence, this brings up the topic ‘Python vs JavaScript: Which One Can Benefit You The Most?’

These two languages are supported by various trending web frameworks and libraries which are the real game-changers. The introduction of these frameworks and libraries to the web ecosystem has brought new paradigms, traditional notions, and standards of software development.
