Relationships where one element depends on another to start or complete. This can apply to tasks in a project, where one task must be finished before another can begin, or to software components, where a program needs a specific library to function correctly. Dependencies are crucial for planning and execution in many fields and must be managed to avoid delays and disruptions.
Set of rules, tools, and processes that streamline the design, construction, and development of digital products.

Free, open-source, high-level Python web framework that enables the rapid development of secure and maintainable websites. It provides a structured framework with pre-built components and tools that handle common web development tasks, allowing developers to focus on writing unique application logic instead of reinventing the wheel. Django is particularly helpful for database-driven websites and offers built-in protection against common web security threats.
Email authentication technology that digitally signs outgoing emails to prevent sender impersonation (known as spoofing). It works by using cryptography: the sender adds a signature created with a private key to the email header, and the recipient’s server verifies it using a public key published in the sender’s domain DNS record. This allows the recipient to ensure that the message comes from an authentic source and has not been modified during transmission.
Advertising flyer format measuring 99 x 210 mm, which is one-third of the A4 format. It is a popular format due to its compactness and ability to convey information effectively.
Instruction that an email service (e.g. MailPoet) gives to email service providers (e.g. Gmail or Yahoo) about what to do if they receive spoofed emails (like in the case of phishing attacks).Setting up DMARC for your domain enables you to control and monitor its usage. Malicious actors may impersonate your domain in their spam or phishing emails. Having a restrictive DMARC policy reduces their ability to do so and improves your deliverability at the same time.
Key element of the internet that translates easy-to-remember domain names, such as „google.com,” into IP addresses that computers can understand (e.g., 172.217.160.142). Thanks to DNS, we don’t have to remember complicated strings of numbers to access a given website. It works like an online phone book, where instead of phone numbers, we have domain names, and instead of names, we have IP addresses.
Open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code, you can significantly reduce the delay between writing code and running it in production.
Way of representing complex XML and HTML documents in the form of an object model. This model is independent of the platform and programming language.
Modern form of outdoor advertising that uses digital media (LED screens, 3D billboards, kiosks) to display dynamic and variable content in public spaces. The main advantages of DOOH are flexibility, the ability to adapt the message to the context (e.g., weather), precise audience targeting, video formats, and the ease of updating content in real time.
Configuration file used by various software applications, especially on Unix-like systems, that is hidden by default because its filename starts with a dot (.). These files store user-specific settings or preferences, such as shell configurations, environment variables, or application-specific preferences
Online sales model in which the seller (store) does not stock the goods but acts as an intermediary between the customer and the wholesaler, who ships the products directly to the end customer. The store owner focuses on marketing and customer service, while their logistics partner (wholesaler or manufacturer) handles the rest of the operations, including storage and shipping. This model allows you to start selling with minimal initial capital and without having to invest in your own warehouse.

It is highly flexible and scalable, with a modular design that allows for customization to create diverse digital experiences, from large government sites to corporate portals.
– software development concept that states every piece of knowledge should have a single, unambiguous, and authoritative representation within a system. Its goal is to reduce repetition and duplication in code, which makes software more maintainable, efficient, and easier to update. Instead of copying and pasting code, developers use abstractions like functions, classes, and modules to represent logic or data in one place
Fundamental concept in computer science that helps you solve problems efficiently. It involves organizing and storing data in ways that make it easy to access and modify.
Process of using computer software to create visual documents like brochures, magazines, newsletters, books, and more. DTP involves combining text, images, and graphics into a layout that is suitable for printing or digital distribution.

Distributed search and analytics engine, commonly used for full-text search, log and event data analysis, and other data-heavy applications. It’s built on top of Apache Lucene, which is a powerful search library, but ElasticSearch enhances its capabilities by adding distributed architecture and real-time data processing.
Encoding is the process of converting information into a specific format, while decoding is the reverse process of converting it back into its original form. The concepts appear in various contexts, such as converting a message into a different language or code (communication theory), compressing and decompressing digital data (video, audio), and teaching children to read.

Function or method used to modify a string so it can be safely included as the value of an HTML attribute, preventing characters like < or > from being misinterpreted by the browser. This process, known as HTML escaping, ensures that the content is treated as a literal string rather than as part of the HTML code, which improves security and prevents rendering errors.
JavaScript code lintering tool that helps find and fix errors in your code. It’s a great tool for writing better code and catching bugs before they reach production. It can be combined with Prettier, a code formatter that ensures consistent style across all your code files.
Dynamic name that refers to whatever the next JavaScript version is at the time of writing. ESNext features are more correctly called proposals, because, by definition, the specification has not been finalized yet.

Time from when the user first opened the page to when any part of the page content was rendered on the screen. For this metric, „content” refers to text, images (including background images), <svg> elements, or <canvas> elements that are not white.
Modern interface in JavaScript that allows you to make HTTP requests. It replaces the older XMLHttpRequest (AJAX) method and provides a cleaner and more flexible way to fetch resources asynchronously. The Fetch API uses Promises, making it easier to work with asynchronous data.
In programming is a function or operation that selects elements from a collection (like a list, array, or set) based on a specific condition. It creates a new data structure containing only the elements for which a given „predicate” function returns true. This is a common technique for restricting a dataset to a subset that meets certain criteria.
