Ruby Proxies for Scale, Performance, and Monitoring - GoGaRuCo - igvita.comIlya Grigorik
Ìý
A high-performance proxy server is less than a hundred lines of Ruby code and it is an indispensable tool for anyone who knows how to use it. In this session we will first walk through the basics of event-driven architectures and high-performance network programming in Ruby using the EventMachine framework.
The simple and practical approach to performance monitoring used at Touristly.

Ìý
What is machine learning? Is UX relevant in the age of artificial intelligence (AI)? How can I take advantage of cognitive computing? Get answers to these questions and learn about the implications for your work in this session. Carol will help you understand at a basic level how these systems are built and what is required to get insights from them. Carol will present examples of how machine learning is already being used and explore the ethical challenges inherent in creating AI. You will walk away with an awareness of the weaknesses of AI and the knowledge of how these systems work.
This document discusses PageSpeed, a tool for just-in-time performance optimization of web pages. It provides automatic image compression and resizing, CSS and JavaScript minification, inline small files, caching, and deferring JavaScript among other optimizations. While most performance issues are well understood, not all websites are fast due to the tradeoff between speed and ease of maintenance. PageSpeed tools like mod_pagespeed can automate optimizations to improve performance without extra work from developers.
0-60 with Goliath: High performance web servicesIlya Grigorik
Ìý
This document discusses Goliath, an open source Ruby web framework for building high performance web services. It provides an overview of Goliath's architecture and goals of optimizing for performance through an asynchronous event-driven model.

The document discusses Goliath, an open source Ruby web framework for building high-performance web services. It provides an overview of Goliath's features like asynchronous HTTP processing, routing, middleware, streaming responses and websockets. Examples are given showing how to write simple Goliath applications and APIs. The document also discusses how Goliath enables building asynchronous apps using techniques like EventMachine and Fibers.
JavaScript is great, but let's face it, being stuck with just JavaScript in the browser is no fun.
Why not write and run Ruby in the browser, on the client, and on the server as part of your next web application?
This document discusses machine learning concepts including algorithms, data inputs/outputs, runtimes, and trends in academia vs industry. It notes that while academia focuses on algorithm complexity, industry prioritizes data-driven approaches using large datasets. Ensemble methods combining many simple models generally perform better than single complex models. Specific ML techniques discussed include word segmentation using n-gram probabilities, perceptrons for classification, SVD for recommendations and clustering, and crowdsourcing ensembles. The key lessons are that simple models with large data outperform complex models with less data, and that embracing many small independent models through ensembles is effective.
No callbacks, No Threads - Cooperative web servers in Ruby 1.9Ilya Grigorik
Ìý
The document discusses using fibers and evented programming with Ruby to achieve asynchronous and concurrent behavior without threads. It introduces EventMachine and EM-Synchrony for implementing asynchronous drivers and applications. Code examples show wrapping database queries in fibers to make them non-blocking. This allows running queries concurrently using a threadpool and achieving higher throughput than blocking implementations. The approach is applied to build an asynchronous version of Rails using EventMachine, fibers and the Thin web server.

Multi-threaded servers compete for the global interpreter lock (GIL) and incur the cost of continuous context switching, potential deadlocks, or plain wasted cycles. Asynchronous servers, on the other hand, create a mess of callbacks and errbacks, complicating the code. But, what if, you could get all the benefits of asynchronous programming, while preserving the synchronous look and feel of the code – no threads, no callbacks?
The document discusses real-time communication technologies for web applications, including XMPP, AMQP, and publish-subscribe protocols. It provides code examples in Ruby of sending messages and presence updates using XMPP, and publishing and subscribing to messages using AMQP. The document promotes these technologies for enabling low-latency messaging between web services and applications.

The document discusses using Ruby proxies with EventMachine to provide transparent scaling, performance improvements, and monitoring capabilities for web applications. Proxies can intercept, cache, and alter requests and responses to balance load across multiple application servers, simulate production traffic for staging environments, and benchmark performance. The EM-Proxy library provides an API and examples for building intercepting, transparent, and other types of proxies with EventMachine for networking applications in Ruby.
A look at the technologies and the architecture behind the emerging real-time web. We will discuss XMPP/Jabber and AMQP protocols and explore the advantages of each over the commonly used HTTP request-response cycle. As part of the workshop we will look at the available tools and libraries and work through simple examples of creating an event driven, real-time service.

AI is transforming talent acquisition by streamlining recruitment processes, enhancing decision-making, and delivering personalized candidate experiences. By automating repetitive tasks such as resume screening and interview scheduling, AI significantly reduces hiring costs and improves efficiency, allowing HR teams to focus on strategic initiatives. Additionally, AI-driven analytics help recruiters identify top talent more accurately, leading to better hiring decisions. However, despite these advantages, organizations must address challenges such as AI bias, integration complexities, and resistance to adoption to fully realize its potential. Embracing AI in recruitment can provide a competitive edge, but success depends on aligning technology with business goals and ensuring ethical, unbiased implementation.
