Introucing Erlang
Download as PPTX, PDF0 likes357 views
Erlang is a programming language designed for writing concurrent programs that run forever. It has a great concurrency model, is network transparent, fault tolerant, and allows replacing running code. Erlang uses processes, immutable variables, recursion, pattern matching, and functional programming. It has built-in support for concurrency through lightweight processes that communicate via message passing. The language philosophy is to "let it crash" and handle errors through recovery in other processes rather than defensive programming.

RabbitMQ is an open source message broker developed by SpringSource that uses Advanced Message Queuing Protocol (AMQP). It is highly distributed, asynchronous, fault tolerant and easy to use. EasyNetQ is an open source .NET client library that provides a simple API for interacting with RabbitMQ. It uses conventions to simplify common tasks like serializing .NET objects to JSON messages and routing messages by type. The presentation demonstrated how to install and use RabbitMQ, EasyNetQ, and some of RabbitMQ's core concepts like exchanges, queues, and routing.仆仂于 仆从亳仂仆舒仍仆仂亞仂 JS

This document discusses functional programming concepts in JavaScript including:
- Pure functions that always return the same output for a given input without side effects. This makes functions more reliable and testable.
- Composition, which combines simple functions to build more complex ones by passing the result of each function to the next. This makes code more readable.
- Immutability, where data cannot be changed once created. New data is created instead of mutating existing data, improving performance.
- The document provides examples and explanations of these functional programming concepts and principles in JavaScript to illustrate how to start writing code in a more functional style.Functional programmning

The document discusses functional programming concepts like pure functions, higher order functions, and referential transparency. Pure functions are those whose return value depends only on their input values, without any observable side effects. Higher order functions are functions that take other functions as arguments or return functions. Referential transparency means a function call can be replaced by its return value without changing the program's behavior. The document argues that functional programming benefits include easier debugging, simpler and cleaner code, and increased reusability. While not all programs can be purely functional, its principles can still be applied.CPP19 - Revision

Akka - A Brief IntroThomas Lockney
油
The actor model provides simple concurrency, resiliency, and elasticity through processing messages sequentially between actors that have no shared state. Actors receive and respond to messages to define their behavior, and can create other actors within the actor system. Key aspects include that actors are not threads, messages are processed sequentially, multiple actors can work concurrently, and exception handling is done through hierarchical supervisor strategies.Creation of threads
Creation of threadsmyrajendra
油
This document discusses key concepts about threads in Java, including: how threads are created by extending the Thread class or implementing the Runnable interface; how context switching occurs voluntarily or through preemption; how threads have priorities from 1 to 10; how synchronization is used with shared resources and monitors; and how threads communicate using notify() and wait() methods.Rethinking the debugger
Rethinking the debuggerIulian Dragos
油
New abstractions for concurrency make writing programs easier by moving away from threads and locks, but debugging such programs becomes harder. The call-stack, an essential tool in understanding why and how control flow reached a certain point in the program, loses meaning when inspected in traditional debuggers. Futures, actors or iteratees make code easier to write and reason about, and in this talk I'll show a simple solution to make them easier to debug. The tool I present integrates well with the Eclipse plugin for Scala, and shows how a "reactive debugger" might look like.Advanced web application architecture - Talk

This document discusses web application architecture and frameworks. It argues that frameworks should not dictate project structure, and that the code should separate domain logic from infrastructure logic. This allows focusing on the core problem domain without concerning itself with technical details like databases or web requests. It also advocates splitting code into ports that define intentions like persistence, and adapters that provide framework-specific implementations, allowing for independence of the domain logic from any particular framework or technology. This architecture, known as hexagonal or ports and adapters, facilitates testing, replacement of parts, and future-proofing of the application.Workflow Patterns and Correlation 3.7

This document discusses concurrency and parallelism in Ruby. It defines concurrency as performing two operations in tandem, while parallelism refers to performing two operations literally at the same time using multiple cores. The document examines traditional approaches to concurrency like threads and locks in Ruby and their limitations. It advocates for adopting models from other languages like actors and software transactional memory that can provide safer concurrency through message passing and transactions rather than shared mutable state and locks. The document reviews several Ruby libraries that implement actors and proposes areas for further improvement in Ruby's core support for concurrent programming.Advanced python

Exception Handling in Python allows programs to handle and recover from errors and unexpected situations gracefully. A try statement runs a block of code and catches any exceptions in except blocks. Even if a statement is syntactically valid, it may cause an error at runtime. Exceptions can be handled through try-except blocks and the finally block is used for cleanup code. Multiprocessing uses multiple processors to run code concurrently for improved speed while multithreading runs multiple threads within a single process using shared memory for lighter resource usage but potential for race conditions.Erlang workshopdrammen

This document discusses the shift towards concurrent programming due to the end of Moore's Law and the rise of multi-core processors. It covers key concepts in concurrent programming like parallelism, concurrency, shared state, synchronization, and message passing. The document recommends using languages and models that avoid shared state through message passing between actors or processes. It introduces several concurrent programming languages - Erlang, Go, Scala, Haskell - that use models like actors or software transactional memory. The goal of the course is to learn concurrent programming idioms using one of these languages.Distributed Model Validation with Epsilon
Distributed Model Validation with EpsilonSina Madani
油
Scalable performance is a major challenge with current model management tools. As the size and complexity of models and model management programs increases and the cost of computing falls, one solution for improving performance of model management programs is to perform computations on multiple computers. The developed prototype demonstrates a low-overhead data-parallel approach for distributed model validation in the context of an OCL-like language. The approach minimises communication costs by exploiting the deterministic structure of programs and can take advantage of multiple cores on each (heterogenous) machine with highly configurable computational granularity. Performance evaluation shows linear improvements with more machines and processor cores, being up to 340x faster than the baseline sequential program with 88 computers.Erlang/Elixir and OTP

The document discusses Erlang/Elixir and OTP. It describes Erlang as a dynamically typed, concurrent, functional language created at Ericsson in 1986 that compiles to bytecode and uses lightweight processes and message passing. It also describes OTP as a set of design guidelines and libraries for building fault-tolerant distributed systems that has been battle tested for over 30 years.

The Missing Voices: Unearthing the Impact of Survivorship Bias on Women in Cl...Imma Valls Bernaus
油
The Cloud Native is missing women's voices. We see it at CNCF conferences and Cloud Native meetups almost everywhere.
While we celebrate women who've "made it", and their visibility is vital, survivorship bias hides a crucial truth: up to half leave tech by age 35, we leave at a higher rate than men, and many never even join.
This talk exposes our own bias as women survivors in tech. The success stories of women around us overshadow the struggles of those who've fallen away, leading to misguided initiatives and hindering true inclusion. There is a dire need to identify and address these issues and implement successful initiatives to make our communities more diverse.
Whether youre a contributor, maintainer, or community leader, this session will give you a deeper understanding of the problem and tangible ways to drive change in your circles. Be part of the solution for a genuinely inclusive cloud native community! Tour Booking, Booking Service, Tour Agents, Hotel Booking in odoo

Migrating GitHub Actions with Nested Virtualization to Cloud Native Ecosystem...KCD Guadalajara

GitHub recently announced the end of support for macOS 12, which was the only GitHub-hosted runner capable of supporting nested virtualization. As a result, many teams relying on this feature for CI/CD workflows face the challenge of migrating existing dependencies to alternative solutions. In this session, I will share my experience migrating workloads from GitHub-hosted runners to a cloud-native solution. By leveraging Actions Runner Controller (ARC), KubeVirt, Tekton, and Longhorn, we were able to provision self-hosted runners on demand, replicating the functionality of nested virtualization while benefiting from the scalability and flexibility of the cloud-native ecosystem. mORMot 2 - Pascal Cafe 2025 in Nederlands
