Development

Java 8 introduced two kinds of functional expressions: lambda expressions like s -> System.out.println(s) and method references like System.out::println. At first, developers were more enthusiastic about method references: they are often more compact, you don't need to think up the parameter name, and, as urban legends say, method references are somewhat more optimal than lambda expressions. Over time, however, the enthusiasm waned. One of the problems with method references is the difficulty in debugging.

This article is aimed to describe FreeBSD OS as a platform to launch cloud guest OSes with simple API capabilities, using MyBee and DevOPS I really like!

We, the PVS-Studio static code analyzer developers, have a peculiar view on beauty. On the beauty of bugs. We like to find grace in errors, examine them, try to guess how they appeared. Today we have an interesting case when the concepts of length and size got mixed up in the code.

Google Colorizing Transformer vs Deoldify

C# has low barriers to entry and forgives a lot. Seriously, you may not understand how things work under the hood but still write code and remain easy-going about this. Though you still have to deal with different nuances over time. Today, we'll look at one of such subtle aspects — handling enumerations.

As a side hustle, I teach tech recruiters web and software development technologies using plain English. It helps them with understanding job specs and resumes and it makes all of us, tech people, happier.

I run a weekly newsletter and often get feedback from recruiters via email or LinkedIn DMs.

I thought that I could try to collect feedback using the “Reactions” feature just like LinkedIn or Facebook does. It’s not as informative as personalised messages but is a simple feature that may incentivize more people to provide some general feedback.

Either way, it’s worth trying and as a software developer, I can’t wait to implement it.

This tutorial is about implementing a feature that will be used in real life on my project.

In this article we will once again return to the tired topic of webinars and webinar hosting tools. And no, we're not about to code a whole new system for webinar hosting – there are already plenty of those. Instead, we will talk about connecting drawing software to the webinar, so that you could manually draw and broadcast the process.

Getting acquainted with the CodeIgniter 4 PHP framework is quite simple.

Spend the evening following the instructions in the «Build Your First Application» section. Since the documentation is written in a good, technically understandable language, it is even possible to get some aesthetic pleasure in the process of familiarizing yourself with this and other sections.

The feeling of airiness and consistency of the CodeIgniter 4 project will be present with you everywhere now.

What is so attractive about CodeIgniter 4?

Goal: continuously send UDP packets from an Arduino Nano 33 IoT to a Raspberry Pi 4 to understand the reliability of this solution.

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.

A few weeks ago we wrote an article about Docker and WebRTC servers and talked about the intricacies of launching containers. Our readers (rightly) questioned whether Docker was a suitable tool for production, for the following reasons:

The potential of VoIP to your customers is simply phenomenal. Businesses are experiencing the advantages of VoIP’s cost-efficiency and reliability and now you can pass these benefits onto your own customers very easily. Cloud telecommunication is sophisticated and easily integrated. Confidence in this technology is growing fast. There has never been a better time to start talking to your customers about adopting this solution. It will deliver huge business benefits for them and has the potential to increase business income and profitability.

The "Click to Call" button on the website is an "innovation" that has been around for about 10 years. The technologies under the hood have changed, but the principle remains the same: someone clicks on the button on the site page, then JavaScript launches and requests access to the microphone and establishes a connection to the server — WebRTC SIP gateway. Further, the first client-server leg is a browser gateway, the second leg can be arbitrarily long and through the SIP proxy chain can eventually connect to a mobile or landline phone. Thus, the browser turns, in a sense, into a softphone and becomes a full participant in VoIP telephony.

Static analyzers' primary aim is to search for errors missed by developers. Recently, the PVS-Studio team again found an interesting example proving the power of static analysis.

Four months of awesome work together with a few new contributors finally result in a new major release, which I'm happy to announce about.

Now we get completely new matrices, improved parser, a lot of new functions, almost rewritten interactive package (for working in Jupyter) and many more.

This article about a big update in a FOSS symbolic algebra library for .NET, I hope it may be interesting for someone!

When creating a .NET library with a partially platform-specific API, we should think about how to pack it into a NuGet package so that the installed library will work in various scenarios (.NET Framework, .NET Core, self-contained application and so on). Unfortunately, it is difficult to find a step-by-step instruction on the web that describes how to perform this task. This article is intended to be such an instruction.

Microservices Architecture is a well-known pattern for building a complex system that consists of loosely coupled modules. It provides better scalability, and it is easier to develop a system in multiple teams so that they don’t interfere with each other too much. However, it is important to choose the right way of communication between the services. Otherwise, this kind of architecture can do more harm than good.

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.
