Guide to naming in code

SemanticsProgrammingDesigning and refactoringIndustrial ProgrammingDevelopment Management
Sandbox

We present a guide to name entities in code based on putting naming in perspectives of semantic space, design, and readability. 

The main idea is that naming should not be considered as creation of tags, but as a fundamental part of design process, which implies integral and consistent vocabulary to be used. We discuss naming process and naming formalism from these perspectives and we provide guidelines for practical use.

The work is based on 15 years of experience in engineering work, coding and development management in high-tech industries.

The architecture of a flexible e-commerce platform on the example of a marketplace

Development for e-commerceE-commerce management

When a company decides to build a marketplace, one of the most critical issues to solve is building interaction between all operational processes.

You need a system where you can manage and exchange customer, partner, and order data. Often the back-office of a marketplace consists of a complex of systems. However, we have been working with marketplaces for many years and have come to the conclusion that the integration between back-office systems should be seamless. At least between 6 fundamental parts. Thus, we have created the Scallium platform, where the business manages the processes of the marketplace.

Application performance monitoring and health metrics without APM

IT systems testingSystem administrationIT InfrastructureWeb services testingService Desk
Translation

I have already written about AIOps and machine learning methods in working with IT incidents, about hybrid umbrella monitoring and various approaches to service management. Now I would like to share a very specific algorithm, how one can quickly get information about functioning conditions of business applications using synthetic monitoring and how to build, on this basis, the health metric of business services at no special cost. The story is based on a real case of implementing the algorithm into the IT system of one of the airlines.

Currently there are many APM systems, such as Appdynamics, Dynatrace, and others, having a UX control module inside that uses synthetic checks. And if the task is to learn about failures quicker than customers, I will tell you why all these APM systems are not needed. Also, nowadays health metrics are a fashionable feature of APM and I will show how you can build them without APM.

How to choose the appropriate level of statistical significance for an AB-test

Web services testingProduct ManagementStatistics in IT

Nowadays a lot of product managers have to confirm most of their decisions with AB-tests. Yet, it is far not always clear how to choose the parameters for the test. A particularly difficult parameter to tune is often the level of statistical significance. If we choose too high level - tests will fail even though improvements do exist. If we choose too low level - we'll be getting lots of "confirmations" of false improvements.

When we make decisions based on AB-tests, once in a while we'll be making mistakes. We can limit the losses caused by such mistakes by choosing the appropriate level of statistical significance.

Telegram bot provides time-based currency

Many of us spend time in specialized telegram groups. The power over communication here belongs to random people with their own shortcomings. Conflict and abuse occurs regularly. Is there another way to keep order so that scam spam doesn't flourish and no one has total control over group members?

In my case, these thoughts led to the development and testing of a system that can be connected to your Telegram today.

Customer feedback: The ultimate guide

SaaS / S+SService DeskGrowth Hacking
Tutorial

Introduction

It was 1989 when 2 editors of Inc. magazine, George Gendron and Bo Burlingham made the nervous drive to Palo Alto, California. Not long beforehand they’d decided on who to name as Inc.’s Entrepreneur of the Decade, and finally, they would get a chance to interview him.

As they entered the offices of NeXT, their interviewee approached them. In his trademark jeans and turtleneck sweater, Steve Jobs led them up the stairs to his office and the interview commenced.

Securing an interview with Steve Jobs was rare, even in 1989. And, wanting to make the most of their time, the editors got straight to the point with their very first question:

“Where do great products come from?”

After a slight pause, and a shuffle in his chair, Jobs replied:

“I think really great products come from melding two points of view; the technology point of view and the customer point of view. You need both. You can't just ask customers what they want and then try to give that to them. By the time you get it built, they'll want something new.”

Silence overshadowed the room. Three decades later, and this powerful answer Jobs gave is something that still isn’t often internalized in companies. 

Collecting user feedback is incredibly important. As you’ll see examples of later in this article, launching surveys, asking onboarding questions, and conducting customer interviews are all vital tools for improving your product. 

But the true lesson that Steve Jobs gave all this time ago was that user feedback isn’t as simple as asking what users want, or what they think about your product, and making those changes. You have to dive much deeper.

Qrator Labs corporate blogInformation SecurityIT InfrastructureNetwork technologiesResearch and forecasts in IT

The year 2021 started on such a high note for Qrator Labs: on January 19, our company celebrated its 10th anniversary. Shortly after, in February, our network mitigated quite an impressive 750 Gbps DDoS attack based on old and well known DNS amplification. Furthermore, there is a constant flow of BGP incidents; some are becoming global routing anomalies. We started reporting in our newly made Twitter account for Qrator.Radar.

Nevertheless, with the first quarter of the year being over, we can take a closer look at DDoS attacks statistics and BGP incidents for January - March 2021.

Roslyn API: Why PVS-Studio Was Analyzing the Project So Long

PVS-Studio corporate blogAPIDevelopment Management

How many of you have used third-party libraries when writing code? It's a catchy question. Without third-party libraries the development of some products would be delayed for a very, very long time. One would have to reinvent the wheel to solve each problem. When you use third-party libraries you still stumble upon some pitfalls in addition to obvious advantages. Recently PVS-Studio for C# has also faced one of the deficiencies. The analyzer could not finish analyzing a large project for a long time. It was due to the use of the SymbolFinder.FindReferencesAsync method from the Roslyn API in the V3083 diagnostic.

Content marketing stamina — the easy way for startup founders to get ahead of their competition

ITMO University corporate blogProject managementDisplay advertisingContent-marketingStart-up development

Content marketing is an endless endurance race. You can’t put a cap on business growth, even if you’re a tech industry giant. A single success is not enough — every time you reach the finish line, it moves further away. Retaining your existing customers is no walk in the park either. When you go silent, you are actively ignoring your audience. There’s no way around it — you need to pump out content.

However, doing that day in and day out requires a lot of stamina. So let’s look at why we get tired in the first place, and figure out how to avoid it. [Previous article: The true cost of free labour].

The step has been made. Not sure where to, but for sure from the point of no return. Keep calm and keep walking. It is about a time to look around and understand the smelly and slippery route before you.

You don't get a buzzing-noise like that, just buzzing and buzzing, without its meaning something.

Architecting Architecture

System Analysis and DesignProject managementSystems engineering
Translation

Architect. This word sounds so mysterious. So mysterious that to understand it you almost forced to add something. Like “System Architect” or “Program Architect”. Such addition does not make clearer, but for sure adds weight to the title. Now you know – that’s some serious guy! I prefer to make undoubtful and around 10 year ago added to my email signature “Enterprise Architect of Information Systems”. It’s a powerful perk. Like “Chosen One”. With architects it is always a matter of naming, you know. Maybe that is why the only way to become and architect is to be named as one by others. Like with vampires. One of them has to byte you! That is probably the easiest way to earn the title as there is no degree or school to grant you one. And if there’s a troubling title, somebody’s making a trouble, and the only reason for making a trouble that I know of is because you’re an Enterprise. Huge old and complex multinational corporation. Like a one-legged pirate. Strong and scary, but not a good runner. You own your ship, you had good days, you have some gold, you need new ways.

To get to new treasures and avoid losing second leg to piranha regulators and local business shark swarming waters near every enterprise ship – every pirate has a map. Map is a list of major features and requirements in desired order and priority.

Have we ever been working by the Waterfall?

Development ManagementAgile

We work using Agile: Scrum, or Kanban, or any other extended project management way. Agile appeared in 2001 as a result of a long discussion between really smart guys. They just formed best practices of management into the shape of short documents - the Agile Manifesto. But what did they want to replace by the Agile way? Most of you may say that they wanted the Waterfall to go to the past. But what would you think if I tell you that the “classical” Waterfall had been a really rare thing even for those days?

Startups going global: a guide to Startup Digest

ITMO University corporate blogDisplay advertisingContent-marketingStart-up developmentLifehacks for geeks

Techstars Startup Digest was designed as a discovery tool for entrepreneurs looking for tech events in their area. It was founded in 2009 by Chris McCann who just moved to the Valley. He created an old-school newsletter, featuring promising events in the Bay Area. There was no website, all the events were hand-picked by Chris himself, and the newsletter had 22 subscribers. People liked the idea and that number quickly grew. In 2012 it was acquired by Startup Weekend. Three years later, Startup Weekend’s parent company UP Global was acquired by Techstars — and that’s how the project got its name.

Startup Digest can be a useful tool for startups and event coordinators. If you can successfully leverage it, your event, blog post and/or tech product can reach thousands of people at no cost.

Ancient times are known to everyone not with immortal works from Homer's only, but also with the Pythagorean multiplication table, Euclidean geometry and the Archimedes screw and the Pi, which we learned to use only relatively recently. In antiquity the art was not only to be able to write poetry and prose, but to design catapults or battering tools also, now there are rigid frameworks, when the discovering the new another beautiful formula is a formal words play only.
Mathematics rules the modern world completely, cynically intertwining with the world of art, intruding with calculations in all spheres of our recreation and everyday life, when the colors of masterpieces turning into poisonous colours.
