Mojo as a_client
Mojo as a_clientMarcus Ramberg Mojo started as an alternative to the aging LWP library for HTTP requests in Perl. It was created by Sebastian Riedel to have a more modern, asynchronous API. Mojo provides an easy to use and full-featured HTTP client and server with support for features like websockets, parallel requests, and more. The library uses a test-driven development approach and strives to have a pragmatic design with reusable components.
Webrtc mojo
Webrtc mojobpmedley This document discusses using WebRTC in Perl to enable real-time communication between browsers. It explains that WebRTC allows peer-to-peer connections without plugins by using signaling to exchange endpoint details and ICE servers. It then provides over 350 lines of Perl code to demonstrate setting up a WebRTC connection between an "offerer" and "answerer" browser to allow sending messages over a data channel. The code connects the browsers as peers, exchanges session descriptions and ICE candidates, creates audio/video constraints, and includes a chat interface to test the connection.

Mojolicious: what works and what doesn't
Mojolicious: what works and what doesn'tCosimo Streppone Mojolicious is a lightweight web framework inspired by Ruby frameworks. It uses PSGI and includes features like ORM, templating, internationalization, and forms. Some key differences between Mojolicious and Dancer are that in Mojolicious the application is defined as a class rather than a script, the code is more "natural" with no magic, and Mojolicious routes are very powerful. What works well about Mojolicious is the good documentation, fast IRC support, powerful routing system, extensive test suite, and clear no dependencies policy. However, the no dependencies policy can cause issues, some tests may not be relevant, and the Template Toolkit renderer requires prefixing all variables with "c.".

Electrify your code with PHP Generators
Electrify your code with PHP GeneratorsMark Baker PHP generators allow functions to behave like iterators by yielding values one at a time rather than building and returning an array all at once. Generators are automatically created when the yield keyword is used in a function. They implement the Iterator interface and can be used in foreach loops. Data and control flow can be passed into generators using the send() method to influence their behavior.
AnyMQ, Hippie, and the real-time web
AnyMQ, Hippie, and the real-time webclkao The document discusses various technologies for real-time web applications including PSGI, Plack, AnyEvent, AnyMQ, server-push technologies like Comet, WebSockets, and the Web::Hippie and Web::Hippie::Pipe modules. It provides code examples of using AnyEvent and POE for asynchronous programming, AnyMQ for publishing messages to different message queues, and Web::Hippie::Pipe for abstracting persistent bidirectional connections. The document advocates for relaxing the definition of "hippies" to support more connection types and demonstrates how Hippie::Pipe can provide a unified interface.

What is PHP? The PHP Programming Language Meaning Explained
Kolade Chris
Kolade Chris
PHP is an open-source server-side scripting language that many devs use for web development. It is also a general-purpose language that you can use to make lots of projects, including Graphical User Interfaces (GUIs).
In this article, I will help you explore the world of PHP so you can learn how it works and its basic features. By the end, you will be able to write your first Hello World program in PHP.
What Does PHP Mean?
The abbreviation PHP initially stood for Personal Homepage. But now it is a recursive acronym for Hypertext Preprocessor. (It's recursive in the sense that the first word itself is an abbreviation, so the full meaning doesn't follow the abbreviation.)
The first version of PHP was launched 26 years ago. Now it's on version 8, released in November 2020, but version 7 remains the most widely used.
PHP runs on the Zend engine, which is the most popular implementation. There are some other implementations as well, like parrot, HPVM (Hip Hop Virtual Machine), and Hip Hop, created by Facebook.
PHP is mostly used for making web servers. It runs on the browser and is also capable of running in the command line. So, if you don't feel like showing your code output in the browser, you can show it in the terminal.
Advantages of PHP
PHP has some advantages that have made it so popular, and it's been the go-to language for web servers for more than 15 years now. Here are some of PHP's benefits:
Cross-Platform: PHP is platform-independent. You don't have to have a particular OS to use it because it runs on every platform, whether it's Mac, Windows, or Linux.
Open Source: PHP is open source. The original code is made available to everyone who wants to build upon it. This is one of the reasons why one of its frameworks, Laravel, is so popular.
Easy to learn: PHP is not hard to learn for absolute beginners. You can pick it up pretty if you already have programming knowledge.
PHP syncs with all Databases: You can easily connect PHP to all Databases, relational and non-relational. So it can connect in no time to MySQL, Postgress, MongoDB, or any other database.
Supportive Community: PHP has a very supportive online community. The official documentation provides guides on how to use the features and you can easily get your problem fixed while stuck.
Who Uses PHP
A number of established companies and tech giants use PHP to run their servers and make a lot of incredible things.
Facebook: Facebook uses PHP to power its site. In turn, the company contributed to the community by creating an implementation known as Hip Hop for PHP.
Wikipedia: one of the world's largest sources of information on any topic, Wikipedia is built in PHP.
Content Management Systems (CMSs): the world's most popular content management system, WordPress, is built in PHP. Other content managem

Using and scaling Rack and Rack-based middleware
Using and scaling Rack and Rack-based middlewareAlona Mekhovova Rack provides a standard interface between web servers and web applications. It allows a web application to return a status, headers, and a body in response to an HTTP request. Middleware can be plugged into a Rack application to modify requests and responses. Popular Rack middleware includes Rack::Cache, Rack::Middleware, and Warden for authentication. In Rails, middleware is configured through an initializer and plugged into the middleware stack to run before or after other middleware.

Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025
Could Virtual Threads cast away the usage of Kotlin Coroutines - DevoxxUK2025João Esperancinha This is an updated version of the original presentation I did at the LJC in 2024 at the Couchbase offices. This version, tailored for DevoxxUK 2025, explores all of what the original one did, with some extras. How do Virtual Threads can potentially affect the development of resilient services? If you are implementing services in the JVM, odds are that you are using the Spring Framework. As the development of possibilities for the JVM continues, Spring is constantly evolving with it. This presentation was created to spark that discussion and makes us reflect about out available options so that we can do our best to make the best decisions going forward. As an extra, this presentation talks about connecting to databases with JPA or JDBC, what exactly plays in when working with Java Virtual Threads and where they are still limited, what happens with reactive services when using WebFlux alone or in combination with Java Virtual Threads and finally a quick run through Thread Pinning and why it might be irrelevant for the JDK24.

Dark Dynamism: drones, dark factories and deurbanizationJakub Šimek Startup villages are the next frontier on the road to network states. This book aims to serve as a practical guide to bootstrap a desired future that is both definite and optimistic, to quote Peter Thiel’s framework.
Dark Dynamism is my second book, a kind of sequel to Bespoke Balajisms I published on Kindle in 2024. The first book was about 90 ideas of Balaji Srinivasan and 10 of my own concepts, I built on top of his thinking.
In Dark Dynamism, I focus on my ideas I played with over the last 8 years, inspired by Balaji Srinivasan, Alexander Bard and many people from the Game B and IDW scenes.

Slack like a pro: strategies for 10x engineering teams
Slack like a pro: strategies for 10x engineering teamsNacho Cougil You know Slack, right? It's that tool that some of us have known for the amount of "noise" it generates per second (and that many of us mute as soon as we install it 😅).
But, do you really know it? Do you know how to use it to get the most out of it? Are you sure 🤔? Are you tired of the amount of messages you have to reply to? Are you worried about the hundred conversations you have open? Or are you unaware of changes in projects relevant to your team? Would you like to automate tasks but don't know how to do so?
In this session, I'll try to share how using Slack can help you to be more productive, not only for you but for your colleagues and how that can help you to be much more efficient... and live more relaxed 😉.
If you thought that our work was based (only) on writing code, ... I'm sorry to tell you, but the truth is that it's not 😅. What's more, in the fast-paced world we live in, where so many things change at an accelerated speed, communication is key, and if you use Slack, you should learn to make the most of it.

AI-proof your career by Olivier Vroom and David WIlliamson
AI-proof your career by Olivier Vroom and David WIlliamsonUXPA Boston This talk explores the evolving role of AI in UX design and the ongoing debate about whether AI might replace UX professionals. The discussion will explore how AI is shaping workflows, where human skills remain essential, and how designers can adapt. Attendees will gain insights into the ways AI can enhance creativity, streamline processes, and create new challenges for UX professionals.
AI’s influence on UX is growing, from automating research analysis to generating design prototypes. While some believe AI could make most workers (including designers) obsolete, AI can also be seen as an enhancement rather than a replacement. This session, featuring two speakers, will examine both perspectives and provide practical ideas for integrating AI into design workflows, developing AI literacy, and staying adaptable as the field continues to change.
The session will include a relatively long guided Q&A and discussion section, encouraging attendees to philosophize, share reflections, and explore open-ended questions about AI’s long-term impact on the UX profession.

Presented by Brent Laster - President & Lead Trainer, Tech Skills Transformations LLC
Talk Title: AI 3-in-1: Agents, RAG, and Local Models
Abstract:
Learning and understanding AI concepts is satisfying and rewarding, but the fun part is learning how to work with AI yourself. In this presentation, author, trainer, and experienced technologist Brent Laster will help you do both! We’ll explain why and how to run AI models locally, the basic ideas of agents and RAG, and show how to assemble a simple AI agent in Python that leverages RAG and uses a local model through Ollama.
No experience is needed on these technologies, although we do assume you do have a basic understanding of LLMs.
This will be a fast-paced, engaging mixture of presentations interspersed with code explanations and demos building up to the finished product – something you’ll be able to replicate yourself after the session!

GDG Cloud Southlake #42: Suresh Mathew: Autonomous Resource Optimization: How...James Anderson Autonomous Resource Optimization: How AI is Solving the Overprovisioning Problem
In this session, Suresh Mathew will explore how autonomous AI is revolutionizing cloud resource management for DevOps, SRE, and Platform Engineering teams.
Traditional cloud infrastructure typically suffers from significant overprovisioning—a "better safe than sorry" approach that leads to wasted resources and inflated costs. This presentation will demonstrate how AI-powered autonomous systems are eliminating this problem through continuous, real-time optimization.
Key topics include:
Why manual and rule-based optimization approaches fall short in dynamic cloud environments
How machine learning predicts workload patterns to right-size resources before they're needed
Real-world implementation strategies that don't compromise reliability or performance
Featured case study: Learn how Palo Alto Networks implemented autonomous resource optimization to save $3.5M in cloud costs while maintaining strict performance SLAs across their global security infrastructure.
Bio:
Suresh Mathew is the CEO and Founder of Sedai, an autonomous cloud management platform. Previously, as Sr. MTS Architect at PayPal, he built an AI/ML platform that autonomously resolved performance and availability issues—executing over 2 million remediations annually and becoming the only system trusted to operate independently during peak holiday traffic.

DevOpsDays SLC - Platform Engineers are Product Managers.pptxJustin Reock Platform Engineers are Product Managers: 10x Your Developer Experience
Discover how adopting this mindset can transform your platform engineering efforts into a high-impact, developer-centric initiative that empowers your teams and drives organizational success.
Platform engineering has emerged as a critical function that serves as the backbone for engineering teams, providing the tools and capabilities necessary to accelerate delivery. But to truly maximize their impact, platform engineers should embrace a product management mindset. When thinking like product managers, platform engineers better understand their internal customers' needs, prioritize features, and deliver a seamless developer experience that can 10x an engineering team’s productivity.
In this session, Justin Reock, Deputy CTO at DX (getdx.com), will demonstrate that platform engineers are, in fact, product managers for their internal developer customers. By treating the platform as an internally delivered product, and holding it to the same standard and rollout as any product, teams significantly accelerate the successful adoption of developer experience and platform engineering initiatives.
