Multithreading allows programs to split into multiple threads to perform tasks concurrently. There are two main ways to create threads: extending the Thread class or implementing the Runnable interface. Threads transition between different states like New, Runnable, Running, Waiting and Dead. Synchronization is needed to control access to shared resources between threads using locks and synchronized methods/blocks. The thread scheduler determines which threads get CPU time based on their priority and state.

S - Single Responsibility Principle.
O - Open Closed Principle.
L - Liskov Substitution Principle.
I - Interface Segregation Principle.
D - Dependency Inversion Principle.
Main goal of this session is to explain in details core aspects of SOLID principles. Code samples are in C# , but SOLID principles are language agnostic and should be applied by any software engineer regardless used programming language.
This document provides an outline for a course on design patterns. The course will cover object-oriented design principles like the SOLID principles, as well as creational, structural, and behavioral design patterns. It will be evaluated based on an exam, report, and participation. The first lecture will review object-oriented programming concepts like encapsulation, inheritance, polymorphism, and abstraction, comparing interfaces and abstract classes. The document also provides examples to illustrate object-oriented design and SOLID principles.
This document discusses the five SOLID principles of object-oriented design: single responsibility principle, open-closed principle, Liskov substitution principle, interface segregation principle, and dependency inversion principle. The single responsibility principle states that a class should have one responsibility. The open-closed principle specifies that classes should be open for extension but closed for modification. The Liskov substitution principle indicates that objects should be replaceable with their subtypes without altering program correctness. The interface segregation principle promotes separating general interfaces into specific ones for client needs. Finally, the dependency inversion principle establishes that high-level modules should not depend on low-level ones but instead both should depend on abstractions.
The first session on design patterns that makes the audience aware of the patterns.
P.S. The implementation are more from explanation perse rather than focusing on being 100% correct. The idea is to make the audience understand patterns rather than putting 100% correct code for the pattern.
The document discusses software design principles for managing complexity and change, including the Open-Closed Principle (OCP), Liskov Substitution Principle (LSP), Dependency Inversion Principle (DIP), and Interface Segregation Principle (ISP). These principles aim to create modules that are open for extension but closed for modification, with subclasses substitutable for their base classes. Dependencies should be on abstractions rather than concretions, and interfaces should be client-specific rather than general. Managing complexity means managing dependencies through high abstraction, single-responsibility classes, and other principles that promote designs that are clean, simple, and elegant.
This document provides an overview of the SOLID principles of object-oriented design:
1. The Single Responsibility Principle states that a class should have one, and only one, reason to change. Having multiple responsibilities makes classes more complex and brittle.
2. The Open-Closed Principle states that software entities should be open for extension but closed for modification. New functionality should be added by extending existing classes rather than modifying them.
3. The Liskov Substitution Principle states that subclasses must be substitutable for their base classes. They should not break the expected behavior of the program.
4. The Interface Segregation Principle states that interfaces should be tailored to specific client needs
This document discusses object-oriented design principles to improve software quality. It introduces principles like encapsulation, the single responsibility principle, the open-closed principle, and the Liskov substitution principle. It explains how these principles, when applied, can help make software more maintainable, flexible, and reusable by reducing coupling between classes and increasing cohesion. Examples are provided to illustrate correct and incorrect implementations of these principles.
The document discusses design principles, patterns, and GRASP patterns. It provides explanations of key principles such as SOLID principles, composite reuse principle, law of demeter, and others. It also explains important design patterns and GRASP patterns. Some key points:
- Design principles like SOLID principles help avoid bad designs and guide developers to create designs that are flexible, understandable, and resilient to change.
- GRASP patterns provide guidelines for assigning responsibilities to classes based on concepts like information expert, creator, and controller.
- Design patterns are proven solutions to common programming problems that can be reused in different situations. Some patterns discussed are creational, structural, and behavioral patterns.
- Applying the right
This document outlines the SOLID principles of object-oriented design, including Single Responsibility Principle, Open-Closed Principle, Liskov Substitution Principle, Interface Segregation Principle, and Dependency Inversion Principle. It defines each principle, provides examples, and discusses the benefits, such as increasing reusability, making code more extensible and flexible, and reducing coupling between modules. Applying these principles helps create software that is well-designed and able to easily handle changes, improving developer and customer satisfaction.
The document discusses SOLID principles and architecture patterns in Android development. It describes the five SOLID principles - single responsibility, open/closed, Liskov substitution, interface segregation, and dependency inversion. It then explains popular architecture patterns like MVC, MVP, and MVVM and compares their advantages and disadvantages. The goal of SOLID and these patterns is to make code more reusable, maintainable, flexible and suitable for team development.
This document discusses SOLID principles for object oriented design. It begins with an introduction of the author and overview of topics to be covered. It then reviews basic OOP concepts and code smells to refactor. The main section defines the five SOLID principles: single responsibility, open/closed, Liskov substitution, interface segregation and dependency inversion. For each, it provides a definition, examples of conforming and non-conforming code, and discusses how it improves design. It closes with other agile/OOP principles and inviting questions.
This document discusses software development principles known as SOLID principles for Android development. It describes the Single Responsibility, Open-Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion principles. Following these principles helps create well-structured, maintainable code that is easily extended over time and avoids software quality deterioration.
This document discusses the SOLID principles for clean code architecture. It explains each principle individually: single responsibility (a class should have one responsibility), open/closed (classes should be open for extension but closed for modification), Liskov substitution (functions using base classes must work with derived classes), interface segregation (split interfaces into smaller interfaces that are focused), and dependency inversion (high level modules shouldn't depend on low level modules). Following these principles helps produce code that is less fragile, more flexible, and easier to maintain and change over time.

This document discusses object-oriented (OO) programming and design compared to structured programming and design. It outlines some of the key advantages of OO including that code is less rigid and fragile, reuse is possible, and viscosity is low when well implemented. Some principles of OO are explained such as objects, classes, inheritance, encapsulation, polymorphism, and design patterns. The document also discusses OO principles like the open-closed principle, Liskov substitution principle, dependency inversion principle, interface segregation principle, and single responsibility principle.

Streaming protocols break down video content into small chunks that are delivered sequentially to viewers for reassembly and playback. This overcomes limitations of standard video formats for storage and playback. Common streaming protocols include HTTP Live Streaming (HLS), Dynamic Adaptive Streaming over HTTP (DASH), and Microsoft Smooth Streaming (MSS). These protocols support features like adaptive bitrate streaming and digital rights management (DRM). DRM uses encryption and licenses to restrict playback of protected content and is implemented through standards like Encrypted Media Extensions (EME) and content decryption modules (CDMs).

Topics covered:
1. What is VictoriaLogs
Open source database for logs
● Easy to setup and operate - just a single executable with sane default configs
● Works great with both structured and plaintext logs
● Uses up to 30x less RAM and up to 15x disk space than Elasticsearch
● Provides simple yet powerful query language for logs - LogsQL
2. Improved querying HTTP API
3. Data ingestion via Syslog protocol
* Automatic parsing of Syslog fields
* Supported transports:
○ UDP
○ TCP
○ TCP+TLS
* Gzip and deflate compression support
* Ability to configure distinct TCP and UDP ports with distinct settings
* Automatic log streams with (hostname, app_name, app_id) fields
4. LogsQL improvements
● Filtering shorthands
● week_range and day_range filters
● Limiters
● Log analytics
● Data extraction and transformation
● Additional filtering
● Sorting
5. VictoriaLogs Roadmap
● Accept logs via OpenTelemetry protocol
● VMUI improvements based on HTTP querying API
● Improve Grafana plugin for VictoriaLogs -

● Cluster version
○ Try single-node VictoriaLogs - it can replace 30-node Elasticsearch cluster in production
● Transparent historical data migration to object storage
○ Try single-node VictoriaLogs with persistent volumes - it compresses 1TB of production logs from
Kubernetes to 20GB

European Standard S1000D, an Unnecessary Expense to OEM.pptxDigital Teacher
This discusses the costly implementation of the S1000D standard for technical documentation in the Indian defense sector, claiming that it does not increase interoperability. It calls for a return to the more cost-effective JSG 0852 standard, with shipbuilding companies handling IETM conversion to better serve military demands and maintain paperwork from diverse OEMs.
3. • A class | A module | A function should have;
• Only ONE purpose
• A class methods and properties should have same goal
• For different properties and different jobs, export them
to another class
Single Responsibility Principle (SRP)
4. A class should have one, and only one,
reason to change.
Do one thing and do it well.
6. Gather together the things that change for the
same reasons.
Separate those things that change for different
reasons.
7. • A class | A module | A function should be;
• Open for extension
• Close for modification.
• Add new functionality without changing existing code
• A change to sub-class shall not need a change on parent
Open/Closed Principle (OCP)
8. Software entities (classes, modules,
functions, etc.) should be open for
extension, but closed for modification.
15. Interface SegregationPrinciple (ISP)
• No child class should be forced to implement not used
methods.
• Split large interfaces into smaller ones
• Split general interfaces into more specific ones
18. A Client should not be forced to implement
an interface that it doesn’t use.
19. Dependency Inversion Principle (DIP)
• High-level modules should not depend on low-level
modules.
• Both should depend on abstractions.
• Abstractions should not depend on details.
• Details should depend on abstractions.
23. • DRY (Don’t Repeat Yourself)
• Each small piece of code may only occur once
• KISS (Keep it simple, Stupid!)
• Piece of software code should be kept simple
• YAGNI (You ain’t gonna need it)
• Never implement a thing before you need them
