Local Dev on Virtual Machines - Vagrant, VirtualBox and Ansible
Developing web applications and websites locally can be troublesome if you use pre-built server packages like WAMP or MAMP, or an install tool to get Java or Ruby on your computer. Develop using modern best practices by using Vagrant, VirtualBox and Ansible to manage your development environments!
Introduction to ansible
Ansible is an IT automation tool that allows users to configure, deploy, and manage applications and infrastructure through code. It uses YAML files called playbooks to execute tasks on remote machines via SSH. Playbooks contain modules that represent tasks like installing packages or restarting services. Ansible has no central server and uses an agentless model. Users create an inventory file that lists hosts and groups, and Ansible uses facts to gather details about remote machines. It can be used for ad-hoc commands or configured playbooks and allows for easy management of infrastructure and applications through code.

Doodling for-great-success
This talk was presented at RubyConfPH 2015, a conference for Ruby programmers.
As coders, we are very familiar with how to communicate using written words. But words exercise only half of our brain. Using sketches to enhance our message leads to more effective communication. It is fun, too!
I discuss sketching tips that everyone - even those who think they have no drawing skills - can use right away. These can be applied to blog posts, open-source documentation, bug reports, and even emails.
Make the most of Rubyconf.ph
This talk is about how to make the most of the upcoming Rubyconf.ph. Most of what I talk about here is also applicable to conferences and meetups in general.
Servers as Pets v. Servers as Cattle
This document discusses the differences between treating servers as "pets" versus treating them as "cattle". Pets are given names and cared for individually, while cattle are treated as interchangeable and replaced when needed. The document traces the evolution of CERN's data centers from a pet model in 2004 to a cattle model by 2010, using configuration management tools to provision servers. It concludes that while cattle are preferable, pets may still be needed in some cases if managed well.
Corona SDK for 4Square Hackathon
The document discusses the Corona SDK, which is a cross-platform framework for building location-based and social mobile apps using Lua. It provides sample code for integrating GPS, compass, Twitter, and Facebook APIs. It also recommends a Corona game template for building prototypes and tips for hackathons such as starting with an interesting story and optimizing the UI. Resources mentioned include the Corona SDK users group in Manila, the Corona game template, RadLib helper functions, Nakor game skeleton generator, and free graphics from Planet Cute.
Active admin
ActiveAdmin is a scaffold generator for the admin component of Rails applications.
Presented at PHRUG meet up, October 18, 2012, hosted by Aelogica PH.
Corona SDK For Fun and Profit
This document discusses using the Corona SDK framework for building mobile games and apps. It describes Corona SDK as a cross-platform framework for building games that uses the Lua programming language. It then provides an example of building a crowd-sourced, location-aware social healthcare app in 15 minutes. Finally, it outlines the basic and pro developer pricing plans for Corona SDK and lists additional Corona SDK resources.

Superpower Your Apache Kafka Applications Development with Complementary Open...
Kafka Summit talk (Bangalore, India, May 2, 2024, https://events.bizzabo.com/573863/agenda/session/1300469 )
Many Apache Kafka use cases take advantage of Kafka’s ability to integrate multiple heterogeneous systems for stream processing and real-time machine learning scenarios. But Kafka also exists in a rich ecosystem of related but complementary stream processing technologies and tools, particularly from the open-source community. In this talk, we’ll take you on a tour of a selection of complementary tools that can make Kafka even more powerful. We’ll focus on tools for stream processing and querying, streaming machine learning, stream visibility and observation, stream meta-data, stream visualisation, stream development including testing and the use of Generative AI and LLMs, and stream performance and scalability. By the end you will have a good idea of the types of Kafka “superhero” tools that exist, which are my favourites (and what superpowers they have), and how they combine to save your Kafka applications development universe from swamploads of data stagnation monsters!

Streamlining End-to-End Testing Automation
Streamlining End-to-End Testing Automation with Azure DevOps Build & Release Pipelines
Automating end-to-end (e2e) test for Android and iOS native apps, and web apps, within Azure build and release pipelines, poses several challenges. This session dives into the key challenges and the repeatable solutions implemented across multiple teams at a leading Indian telecom disruptor, renowned for its affordable 4G/5G services, digital platforms, and broadband connectivity.
Challenge #1. Ensuring Test Environment Consistency: Establishing a standardized test execution environment across hundreds of Azure DevOps agents is crucial for achieving dependable testing results. This uniformity must seamlessly span from Build pipelines to various stages of the Release pipeline.
Challenge #2. Coordinated Test Execution Across Environments: Executing distinct subsets of tests using the same automation framework across diverse environments, such as the build pipeline and specific stages of the Release Pipeline, demands flexible and cohesive approaches.
Challenge #3. Testing on Linux-based Azure DevOps Agents: Conducting tests, particularly for web and native apps, on Azure DevOps Linux agents lacking browser or device connectivity presents specific challenges in attaining thorough testing coverage.
This session delves into how these challenges were addressed through:
1. Automate the setup of essential dependencies to ensure a consistent testing environment.
2. Create standardized templates for executing API tests, API workflow tests, and end-to-end tests in the Build pipeline, streamlining the testing process.
3. Implement task groups in Release pipeline stages to facilitate the execution of tests, ensuring consistency and efficiency across deployment phases.
4. Deploy browsers within Docker containers for web application testing, enhancing portability and scalability of testing environments.
5. Leverage diverse device farms dedicated to Android, iOS, and browser testing to cover a wide range of platforms and devices.
6. Integrate AI technology, such as Applitools Visual AI and Ultrafast Grid, to automate test execution and validation, improving accuracy and efficiency.
7. Utilize AI/ML-powered central test automation reporting server through platforms like reportportal.io, providing consolidated and real-time insights into test performance and issues.
These solutions not only facilitate comprehensive testing across platforms but also promote the principles of shift-left testing, enabling early feedback, implementing quality gates, and ensuring repeatability. By adopting these techniques, teams can effectively automate and execute tests, accelerating software delivery while upholding high-quality standards across Android, iOS, and web applications.
