Enterprise IT architecture, or system architecture, is a hybrid environment of applications and systems distributed across on-premise data centers, cloud infrastructure, edge computing, IoT networks, and other platforms. It spans different physical locations of the machines and various service providers, whether a company uses IaaS, PaaS or SaaS solutions, or a hybrid environment. Let’s see how system…

What is a Production Monitoring System, and how can it improve manufacturing processes?

Why is production monitoring critical? Manufacturing is a very complex process, and each part of it has the potential for significant optimization, which could increase profits and reduce production costs. Conversely, each part of the process can malfunction and lead to unnecessary expenses, material losses, delays, or workplace injury.  No wonder, then, that a Production Monitoring System (PMS; sometimes called Shop Floor Monitoring System) is necessary for companies in all manufacturing industries – whether it’s pharmaceutical, food, chemical, or automotive production. What is a production monitoring system? Production monitoring, or shop floor monitoring system, allows production managers and operators to monitor…

How to do your null-checks safely in JavaScript

How to do your null-checks safely in JavaScript

Checking if the value is null or undefined in JavaScript (and TypeScript) can be a real headache and doing it incorrectly can lead to unexpected errors during runtime.  In most strongly typed languages the value can be either null or not, however that’s unfortunately not the case in JavaScript.   In JavaScript, you will encounter null or undefined. To make life even harder, there are also double (abstract ==) and triple (strict ===) equality comparisons which combined with null/undefined confusion can be a challenge, especially for beginners.   Let’s start with a little theory, and later I’ll guide you through examples and finally show you a painless (and safe!) way to do the null checks in the code.  Equality comparison  There are three value-comparisons in operations in JavaScript:  == Abstract Equality…

How to avoid ten common mistakes in data visualization?

How to avoid ten common mistakes in data visualization?

John W. Tukey, the founding member of Princeton’s statistics department and the author of the software term,  once said that if you torture the data long enough, it will tell you anything. His work of life was to take boring, flat data and bring it to life through visualization. However, he was aware of the misconstructed data. It leads to publishing misleading visualization, which results in the audience’s mistrust. Let’s check then what design factors make visualizations stand out? How can designers convey the meaning of data with desired clarity? Read the article to find out.   How do we perceive data?  Data visualization focuses on human sight, and cognition is the most incredible natural phenomenon. Human brains work in such a way as to catch the most critical…

IT project visualization. Types, examples, and tips

IT project visualization. Types, examples, and tips

Visualization is one of the most popular methods of analyzing and communicating information. This article will try to present several visualization methods in an IT project. It will tell you how to simplify sharing knowledge in a team.  Is the documentation in an IT project necessary?  Developers’ opinions regarding the need for creating the documentation are strongly divided. On the one hand, the documentation responds to the problem of storing knowledge in a narrow group of people, an example of which is the Bus Factor and the occurrence of the so-called Heroes in the IT project. On the other hand, documentation, like code, needs to be maintained,…
