Website development *

The PVS-Studio website turns 15 this year. This is quite significant for any internet resource. Back then, when our website was born, Russia announced 2006 as a year of humanities. That same year, in June, Denis Kryuchkov established a new platform, "Habrhabr" (now known as Habr). In November, Microsoft officially completed OS Windows Vista. That same month we registered the viva64.com domain.

We celebrated our domain's 10th anniversary with the website's redesign. After that, we would only change the resource capacity and features, but we'd never touch the design in any way. During this time, the number of articles grew so much that we needed to add tags to facilitate navigation. Right now we are also working on our YouTube channel. This means, you will see more and more new videos on our website as well. We keep adding new web pages at a tremendous rate, while the website's usability stays the same.

Time has come for big changes!

It may seem that when you are a beginner, you'll do simple things only. No need to learn data structures and algorithms. No need to understand Big O notation, complexity and stuff like that. 

This couldn't be further away from the truth!

In 2008, when I just started learning to program, I spent a lot of time reading books on PHP and MySQL. Months later, when I felt confident, I took my first freelance project. It was a real estate website. A simple one. I used a custom-made ORM and everything worked just fine!

When I released it, the search feature quickly became sluggish and made the website unusable. 

I was wondering what the heck had happened. I figured out that database queries became very slow when there were over 200 real estate objects added to it. 

This is it. What worked fine during testing did not work in real life.

I was a self-taught developer. I did not know how to measure if my project scaled well. I didn't even know that I had to do it.

I thought algorithms mattered only for launching a spaceship.

If I had some basic understanding of algorithms, I would have known that the more the input, the longer it takes. 

I am not saying I would have come up with a robust solution as a junior, but I would have looked for a solution because I knew there would be a problem. 

Please, don't make the same mistake!

Of course, data structures and algorithms are much more than that and they apply differently depending on what you work on.

But a basic understanding of data structures and algorithms is a must for every software developer. 

• Streaming of content from the rich text editor to other infrastructure tools like full-text search, warehouses, etc.
• Retrieving of content to clients: mobile, web, desktop.
• Storing of content in some kind of storage (SQL database in my case)
• Analyzing of content, which includes point 1, but also analyzing it from the perspective of our application

An eCommerce platform empowers startups, SMEs, and large enterprises to manage multiple online business processes such as website, marketing, sales, and operations.

The top eCommerce platforms handle online business tasks efficiently, and this finally helps enterprises in expanding their productivity.

Thousands of new online businesses created daily. Dozens of different platforms work like real mega plants to meet the needs of humanity. In recent years, the Shopify occupies a leading position in the market and continues to gain momentum. Shopify's functionality is expanding rapidly, but sometimes even it's not enough. We want to show how you can integrate the accounting Netvisor to your newly made e-shop and what benefits you get at it.

Based on practice, even the simplest data analysis can lead to a significant reduction in CPA. Advertising campaigns on Facebook are no exceptions and need to be optimized over time. Often under optimization, you can see experiments with different types of audiences and targeting. If you want to get more conversions within the same budget, then you should pay attention to a few crucial points that we will consider in this article.

Ruby programmers around the world are participating in an increasing number of conferences where they gather to share reports on unfinished projects, discuss the future of Ruby, and welcome newcomers to the community. At such conferences, new ideas are born and a lot of inspiration comes for real masters of their craft. Let's take a look at the list of the main events of the Ruby community.

JavaScript is a multi-paradigm language. It supports event-driven, functional, and imperative, including object-oriented and prototype-based, programming styles. JavaScript was initially used only for client side. These days JavaScript is used as a server-side programming language as well. To summarize in just one simple sentence — JavaScript is the language of the web.

Custom development is different from commercially distributed software or existing open source software. Individual development either creates a new application or expands the functionality of an existing one and can be executed by its own or third-party developers.

How do you know that it’s time for you to launch your online marketplace? When do you see the necessity to provide the ultimate clear and fast “brand – consumer” communications? The point of an online marketplace is to grow customers loyalty by offering them an ever-expanding range of products.

A brand, whether online or not, must use its reputation and expertise to make its marketplace successful.

Let's take a look at the benefits of marketplaces and the reliability of Ruby on Rails as the strongest development tool.

Choosing between Node.js and Ruby on Rails, when choosing a development platform, is a core decision. That affects how the project unfolds over time, and how much server resources will be needed. Both languages can support web applications of high complexity, but each has its advantages and disadvantages. Knowledge of these pros and cons will help to choose the best solution for the proposed project. Let's analyze in more detail and tell you about our choice and experience.

The manual work of the accountant went into oblivion. Today everyone makes machines, but, of course, controlled by a specialist. Although in our last project we have carefully worked on the topic of artificial intelligence and some accounting operations can already occur with little or no human intervention. Let's look at what systems we attracted, and what exactly was done to save time on daily routine operations.

Implementation a web UI is faced with more and more complex tasks that require the use of more and more complex tools. The trend of leaving the MVC application architecture, as well as the desire of developers to use separate libraries for each layer of tasks, led to changes, against which the Vue.JS framework appeared and became popular. Let's try to understand why Vue.JS appeared and what problems it carefully solves.

E-commerce today has become so frequent that it has become almost a standard chain of stores, where most people make purchases. But even online stores are trying to save money by becoming drop shippers and more working on additional implementations, rather than on the maintenance and payment of huge storage spaces.

Development in its pure form is not only writing code, but also a number of manipulations that are necessary for its correct and timely work. Testing in development takes the lion's share of both time and resources, but proper testing will bring only time savings and the best result for the client.

Many corporations today only a few years ago started their business with MVP. The only MVP allows you to take a look in a very short period how your business will move. By this way, you can notice at the first reaction of the target audience, see all the shortcomings, and exactly decide how to proceed further: develop the idea and invest in or completely modify it in an absolutely different product.
