It concludes by thanking the audience and providing Alexey's contact information.
This document discusses various options for hosting Ruby applications, including common Ruby web frameworks, web servers like WEBrick and Mongrel, and FastCGI. It notes the pros and cons of each option and how they are impacted by common hosting limitations. It recommends considering deployment tools and control panels to assist with hosting and concludes by offering help from Redgem projects and thanking the event organizers.
Async ... Await – concurrency in java scriptAthman Gude
This document discusses concurrency in JavaScript and how async/await helps improve asynchronous code. It covers:
- Concurrency involves doing multiple tasks over time in order or partially ordered ways. JavaScript uses non-blocking I/O with an event loop.
- Blocking code can halt everything, so JavaScript uses callbacks for asynchronous operations like network requests.
- Promises help solve issues with callbacks but still require callback functions. Async/await allows writing asynchronous code that looks synchronous using generators and promises under the hood. It provides better readability and error handling than callbacks or promises alone. Developers must still be careful about parallelism and await usage.

This document discusses asynchronous templating in Node. It describes the history of blocking templating in PHP and Ruby on Rails. It introduces Asynchronous JavaScript (AJS), a new templating library for Node that allows templates to continue rendering while waiting for asynchronous callbacks. AJS works by parsing templates to an AST, adding hooks around callbacks, recompiling optimized JavaScript, and executing in a VM. It aims to provide a familiar syntax while being fully non-blocking.
The document discusses the Merb web framework. It highlights Merb's advantages over Rails such as being smaller in size with fewer lines of code, having a shorter call stack, and being more modular and flexible through its use of gems.

Knowledge of how to set up good benchmarks is invaluable in understanding performance of the system. Writing correct and useful benchmarks is hard, and verification of the results is difficult and prone to errors. When done right, benchmarks guide teams to improve the performance of their systems. When done wrong, hours of effort may result in a worse performing application, upset customers or worse! In this talk, we will discuss what you need to know to write better benchmarks for distributed systems. We will look at examples of bad benchmarks and learn about what biases can invalidate the measurements, in the hope of correctly applying our new-found skills and avoiding such pitfalls in the future.
This document discusses concurrency errors in Java and how to avoid them. It begins by defining a concurrency error as the result of incorrect synchronization that can cause issues like race conditions and starvation. It notes that concurrency errors can lead to data corruption, security vulnerabilities, and incorrect behavior. While Java includes synchronization primitives, concurrency is still tricky and errors can occur if the primitives are used incorrectly or without properly designing the concurrency model. The document provides examples of potential concurrency errors and ways to avoid them, such as locking on an appropriate shared object to ensure atomic read/write operations. In the end, it emphasizes the importance of remaining vigilant about concurrency through tools, analysis, and careful design.
Project Loom aims to bring asynchronous programming to Java with virtual threads. Virtual threads allow blocking code to run asynchronously by scheduling continuations across lightweight threads. This avoids the "blue world" problem of rewriting synchronous code for asynchronous systems. It also enables scaling applications by utilizing non-blocking I/O without changing existing code or libraries. While virtual threads are not yet production-ready, Project Loom has the potential to improve scalability for Java applications without a major paradigm shift.
The document discusses asynchronous programming with async and await in C#. It explains that async and await were introduced to address issues with threading like overhead and blocking. Async methods use threads efficiently from the thread pool rather than creating new threads. Await yields threads rather than blocking them. The document demonstrates async programming and best practices like using Task instead of async void. It recommends using async for I/O bound work since it can improve performance over synchronous code.
This is an interactive PowerPoint presentation I made for my seminar at my workplace. It talks and illustrates how the JavaScript engine works when executing code. It also contains a step-by-step animation which demonstrates the usage of the JavaScript event loop.

Lixun Peng presents Double Sync Replication as a solution to problems with asynchronous and semi-synchronous replication. Double Sync Replication uses two replication channels - an asynchronous channel to continuously replicate binary logs from the master, and a semi-synchronous channel to replicate the latest binary logs and position. This allows the slave to always know the latest position on the master and compare logs from both channels to determine consistency. The asynchronous channel is used to fully apply logs when the network is down to catch the slave back up.
The document discusses the Play! web framework. It covers getting started with Play!, error handling, the difference between threaded and evented models, asynchronous features, and concludes with a summary. The key points are that Play! follows a MVC pattern with Java and Scala APIs, uses the Akka framework for asynchronous behavior, supports hot reloading of code and templates, and aims to have predictable scalability through non-blocking I/O.

This document discusses ways to make test suites run faster. It presents three approaches: being a cheater by using faster machines and parallelizing tests; being lazy by deleting unused tests and code and using in-memory databases and servers; and being brave by breaking long integration tests into smaller pieces, mocking slow layers, and minimizing browser testing. The key message is that there are many simple tricks that can significantly speed up test runs without major refactoring efforts.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
2. Programme
• Async programming késaco ?
• How we do it in javascript ?
- callback
- Promise: then / async/await
• Observable to the rescue.
• Iterator <==> Observer
18. Promise are not perfect also
• Callback Hell
• Error handling - kinda suicidal
• No control
• Only resolve once (not suitable for events)
• Not cancellable
• Always Asynchrone
21. For me…
• Observable = data + time (kinda promise but
continuously)
• Hum sounds familiar: Streams is a sequence of data
elements made available over time. (Wikipedia)
•
