The myth of error-free programming

Level of difficultyEasy
Reading time3 min

There have been many discussions about which programming language is better in terms of security and correctness of source code (by "correctness and security" we mean the absence of various errors in the program that manifest themselves at the stage of its execution and lead to the issuance of an incorrect result or unexpected behavior). And some programming languages, such as SPARK or OCaml, were even specially developed to facilitate the proof of program correctness.


Is it possible to write programs without errors at all?

Portfolio is one of the most important things a UX designer should have - it plays a defining role during the job application process. In professional circles it is even called a designer’s “calling card”. Portfolio is not just a collection of your work - it’s your way to present yourself, your problem-solving skills and your talent. No matter whether you’re a freelance designer who posts their portfolio online to attract clients, or if you prepare a portfolio for the HR team at a job interview, you should try to make it look both serious and interesting, while not overloading it with too much information. In this article we’ve collected a list of components that a good portfolio should contain and mistakes that should be avoided when compiling it - let’s discuss them.

Beyond the Engine: The Six Levels of Software-Driven Car Evolution

Reading time7 min
Views861

Cars are among the most technologically advanced consumer-level devices on the market. They have been shaping lifestyles, laws, supply chains, and many other aspects of human society's evolution.

But today, we’re witnessing a silent revolution – one driven not by hardware, but by software. Modern cars are no longer just machines; they’re dynamic, evolving platforms powered by code. This transformation is reshaping every aspect of the automotive industry, from design and manufacturing to ownership and recycling.

In my latest article, I explore six levels of evolution brought about by software’s growing role in vehicles and related fields:

Capabilities - Over-the-air updates and digital twins unlock new features and extend hardware lifespans.
Design - Digital platforms replace manual processes, enabling faster innovation.
Architecture - Modular systems open doors to new partnerships and revenue streams.
Engineering - Agile, feature-centric paradigms align hardware and software development.
Manufacturing - Factories become dynamic, software-driven ecosystems for flexibility and sustainability.
Lifecycle - Software extends vehicle lifecycles, from supply chains to closed-loop recycling.

This transformation isn’t just about technology – it’s about reimagining the industry itself. Do we need a revolution to achieve a better, more sustainable future, or do we already have the tools to evolve?

The automotive industry is at a crossroads. For engineers, it demands fluency in code. For industries, it requires agility. For the planet, it offers a roadmap to reconcile mobility with sustainability.

The road ahead is coded, but the destination is open-ended – shaped by collaboration, innovation, and the choices we make today.

Eco-Methodological Sustainability

Reading time6 min
Views868

In recent years, discussions about the environmental impact of information and communication technologies (ICTs) have largely revolved around hardware — data centers, electronic waste, and energy consumption. However, an equally important factor has been overlooked: the software development methodologies themselves.

When I read the UNCTAD “Digital Economy Report 2024, I was struck by the complete absence of any mention of how programming methodologies impact sustainability. There was no discussion of whether developers use algorithm-centric or code-centric methodologies when creating software, nor how these choices affect the environment.

This realization led me to introduce the concept of Eco-Methodological Sustainability — a new approach that highlights the role of structured software development methodologies in shaping an environmentally sustainable future for the digital economy.

Up to a certain point, I sincerely believed that in today’s world manual CAPTCHA recognition was gradually becoming an anachronism, especially when it came to such simple CAPTCHAs as image-based ones—where one merely needs to read text off a photograph and input it as plain text. But as it turns out, things aren’t quite so straightforward (no matter how it may sound).

An in-depth comparison of the three main kinds of runtime type checkers to my new tool

tl;dr; in the modern TS/JS landscape and overall tooling trends, better stick with static code generators, they are more performant in many ways, easier to integrate into apps, other tools and the multitude of modern JS runtimes. My new tool is as good as other static code generators, but it also produces strictly type safe code and unit tests for you.

This post goes into a rather deep comparison of my new tool Type Predicate Generator (from here just Generator) to other runtime type checkers, also giving a rather broad overview of the related topics. To get a sense of what it does try checking the Playground first.

If you're about to create your first tool for the TypeScript ecosystem the insights in this article will help you hit the ground running.
