Programming *

Hello!

[UPD from 12.06.2021: if you're looking for a symbolic algebra library, AngouriMath is actively developed. It's on Github and has a website. Discord for questions]

Why does programming a calculator seem to be a task, which every beginner undertakes? History might have the answer — computers were created for this exact purpose. Unlike the beginners, we will develop a smart calculator, which, although won't reach the complexity of SymPy, will be able to perform such algebraic operations as differentiation, simplification, and equations solving, will have built-in latex support, and have implemented features such as compilation to speed up the computations.


Let's do it!

2020 is going to be a competitive year especially for business people. A large number of startups and small businesses are outsourcing their projects to the best web development agencies because of the skilled resources, outsourcing-friendly policies, high-quality work, affordable price and favorable time zones they have.

But selecting a good company can be a daunting task because we are surrounded by a pool of such companies today. Keeping this in my mind, I have shortlisted some of these companies to help you choose the best one which offers world-class web development services at affordable rates.

I have checked the diversified portfolio, their tech teams expertise, client’s feedback, reviews from sites like Goodfirms and Clutch before making this list. Moreover, I have taken references from some popular platforms viz. hackernoon, dev.to, yourstory, quora, medium and habr.

Lets' dive into my research work on this which would surely meet your business requirements.

Psychology plays an important role in the success of any marketing strategy. Attracting people to your app needs the right psychological approach. Human behaviors are highly crucial which are required to be considered while forming strategies.

Simplest thing in application affects their interactivity greatly. For example, even the number of notifications, as well as the time at which they will be sent, have a strong impact. According to a survey, 60% of respondents have a preference for what time of day they receive notifications.



This indicates that the way an app will communicate with users will have an immense effect on its success or failure. Do you know what are the factors that affect the interactivity of your app? Apart from that, how can you make an app interactive?

One of the modules in the Windows kernel provides support for combining a set of file operations into an entity known as a transaction. Just like in databases, these entities are isolated and atomic. You can make some changes to the file system that won't be visible outside until you commit them. Or, as an alternative, you can always rollback everything. In any case, you act upon the group of operations as a whole. Precisely what needed to preserve consistency while installing software or updating our systems, right? If something goes wrong — the installer or even the whole system crashes — the transaction rolls back automatically.

From the very first time I saw an article about this incredible mechanism, I always wondered how the world would look like from the inside. And you know what? I just discovered a truly marvelous approach to force any process to operate within a predefined transaction, which this margin is too narrow to contain. Furthermore, most of the time, it does not even require administrative privileges.

Let's then talk about Windows internals, try out a new tool, and answer one question: what does it have to do with sandboxes?

If you're reading this text, you've either thought that something was wrong with the headline or you've seen the name of a familiar computer game. VVVVVV is an indie platformer game that has stolen the hearts of many players by its pleasant external simplicity and no less pleasant internal complexity. A few days ago, VVVVVV turned 10 years, and the author of the game — Terry Cavanagh — celebrated this holiday by publishing its source code. What mind-boggling things is it hiding? Read the answer in this article.

Machine learning has firmly entrenched in a variety of human fields, from speech recognition to medical diagnosing. The popularity of this approach is so great that people try to use it wherever they can. Some attempts to replace classical approaches with neural networks turn up unsuccessful. This time we'll consider machine learning in terms of creating effective static code analyzers for finding bugs and potential vulnerabilities.

Visual Studio 2019 versions 16.3 and 16.4 include improvements to the C++ inliner. Among these is the ability to inline some routines after they have been optimized, referred to as the «Zipliner.» Depending on your application, you may see some minor code quality improvements and/or major build-time (compiler throughput) improvements.

A client contacts you via Telegram, asking you to develop website that will be the meeting place for the employer and the employee to conduct an in-person interview. In-person means face-to-face, a direct video contact in real time with video and voice. «Why not use Skype?» some may ask. It just so happened that serious projects – and each startup undoubtedly considers itself a serious project – are trying to offer an internal communications service for a variety of reasons, including:

Virtual reality is on the rise these days. The equipment that was previously the exclusive preserve of crazy scientists geeks with big money from the Ministry of Defense back in the The Lawnmower Man days, is currently affordable for ordinary people; those whose pockets are empty, can assemble a VR headset from cardboard and a smartphone according to many recipes.

Hyper-V is more known as a server virtualization technology; however, since Windows 8, it is also available in the client operating system. In Windows 10, Microsoft improved the experience drastically to make Hyper-V an excellent solution for developers and IT Pros.
 
Microsoft Hyper-V, codenamed Viridian, is a native (type 1) hypervisor that directly runs on the hardware, compared to VMware Workstation, VirtualBox, and other type 2 or hosted hypervisors. It was first released in Windows Server 2008, and it allows you to run virtual machines on x86-64 systems.

As mentioned, with Windows 10, Microsoft optimized Hyper-V for developers. Hyper-V allows developers to quickly spin up development virtual machines on Windows 10 with excellent performance, but it is also used in a couple of other development features as a back-end technology, like the Android Emulator, the Windows Subsystem for Linux 2 or Docker Containers. In this article, we will have a quick look at what Hyper-V on Windows 10 can over for developers.
