Video: HTML5 Fundamentals (Bulgarian)
Video lecture about the fundamentals of HTML5.
The video is recorded in 2015 in a training I was delivering in Telerik Academy.
Hypertext Markup Language (HTML) is a standard markup language used for creating web pages. HTML concepts include elements, attributes, and tags. An HTML document has a standard structure, including a doctype declaration, a head section, and a body section.
Common HTML elements include headings, paragraphs, links, images, and lists. Section elements, such as <header> and <footer>, provide additional structure to web pages.
Semantic structural tags, such as <nav>, <main>, and <article>, provide meaning to the content and structure of a web page. These tags help search engines and assistive technologies understand the content, making web pages more accessible and easier to navigate. By using semantic structural tags, developers can create more meaningful and accessible web pages.
Topics covered:
- Hypertext Markup Language
- HTML Concepts
- HTML Document Structure
- HTML Common Elements
- Section Elements
- Semantic Structural Tags
Video: Tools for HTML, CSS and JS (Bulgarian)
Video lecture about the tools for HTML, CSS and JS development and debugging.
The video is recorded in 2015 in a training I was delivering in Telerik Academy.
IDEs, or Integrated Development Environments, are coding tools that provide a comprehensive workspace for developers to write, test, and debug code. Some popular IDEs include Sublime Text, Atom, WebStorm, and Visual Studio. These tools typically include features such as syntax highlighting, code completion, and integrated debugging tools.
Browsers and browser tools are essential for testing and debugging web pages. Common browsers include Google Chrome, Mozilla Firefox, and Apple Safari. Browser tools, such as the browser's developer console, allow developers to inspect and debug HTML, CSS, and JavaScript code.
Drawing and slicing tools are used in web design to create graphics and convert them into web-friendly formats. Examples of drawing tools include Adobe Illustrator and Sketch, while slicing tools, such as Adobe Photoshop, are used to divide a design into smaller, web-optimized pieces, such as images and buttons. These tools are essential for creating high-quality graphics and user interfaces for web pages.
Topics covered:
- Coding Tools (IDEs)
- Sublime Text
- Atom
- WebStorm
- Visual Studio
- Browsers and Browser Tools
- Drawing and Slicing Tools
Video: Web Technologies Basics (Bulgarian)
Video lecture about the basics of web technologies.
The video is recorded in 2015 in a training I was delivering in Telerik Academy.
Web sites and web applications are the foundation of the World Wide Web. Web 1.0, 2.0, and 3.0 describe the evolution of the web, with each stage bringing new capabilities and user experiences. Web browsers are the software applications used to access web pages and web applications, while hardware servers host web sites and web applications. Web servers are software programs running on hardware servers that serve web pages and web applications to users.
The client-server architecture is the underlying architecture of the web, where a client (such as a web browser) requests data from a server (such as a web server) and the server returns the requested data. 3-tier and multi-tier architectures refer to more complex systems, where the client, server, and database are separated into distinct components.
Service-Oriented Architecture (SOA) is a method for designing and building web-based systems, where each component is a self-contained "service" that communicates with other services through a common interface. This approach makes it easier to develop, maintain, and evolve large-scale web applications.
Topics covered:
- Web Sites and Web Applications
- Web 1.0, 2.0, 3.0
- Web Browsers
- Hardware Servers
- Web Servers
- Client-Server Architecture
- 3-Tier / Multi-Tier Architectures
- Service-Oriented Architecture (SOA)
Video: Windows and Windows-based Applications History (Bulgarian)
Video lecture about the history of Windows and Windows-based applications.
The video is recorded in 2015 in a training I was delivering in Telerik Academy.
Windows OS is a widely used operating system for desktop and mobile devices. The history of Windows OS for desktop dates back to Windows 3.0 and has evolved through various versions, culminating in Windows 10. Similarly, the history of Windows OS for mobile began with Windows CE and has evolved through Windows Mobile, Windows Phone, to Windows 10 Mobile.
There are several ways to develop Windows applications, including using MFC, WinForms, WPF, and the Universal Windows Platform (Win10). Universal Windows Apps were introduced in Windows 8.1 and allowed developers to create apps that could run on multiple devices. The Universal Windows Platform (Win10) provides a common platform for building Windows apps that can run on a variety of devices, including desktops, tablets, and smartphones.
In addition to these platforms, there are other platforms for developing Windows apps, such as Unity3D, Xamarin, and Apache Cordova. These platforms provide alternative options for building Windows apps and allow developers to utilize their existing skills and knowledge.
Topics covered:
- History of Windows OS for Desktop
- From Windows 3.0 to Windows 10
- History of Windows OS for Mobile
- From Windows CE to Windows Mobile to Windows Phone to Windows 10 Mobile
- Ways to Develop Windows Applications
- MFC, WinForms, WPF
- Windows Universal Apps (Win 8.1)
- Universal Windows Platform (Win10)
- Other Platforms for Windows Apps
- Unity3D, Xamarin, Apache Cordova
Video: Entity Framework Code First (Bulgarian)
Video lecture about the code first approach in Entity Framework.
The video is recorded in 2014 in a training I was delivering in Burgas, Bulgaria.
Entity Framework Code First is a method of developing software applications that utilizes the Entity Framework and focuses on the code-first approach. The modeling workflow of Entity Framework Code First involves defining domain classes or models that represent the objects in the application. These models are then used to create a database using the DbContext and DbSets classes.
A database connection is established and managed by the DbContext class, and the database is created based on the models defined in the domain classes. Code First Migrations are used to manage database changes and keep track of the evolution of the database over time.
The mappings between the domain classes and the database are configured using either Data Annotations or Fluent API. Data Annotations are attributes that are added to the models to specify the properties of the database, such as the primary key, data type, etc. Fluent API is a more flexible way of defining mappings that allows developers to use a fluent API syntax instead of data annotations.
Topics covered:
- Modeling Workflow
- Code First Main Parts
- Domain Classes (Models)
- DbContext and DbSets
- Database connection
- Using Code First Migrations
- Configure Mappings
- Data Annotations and Fluent API
