Richardrodger nodeday-2014-final
Richardrodger nodeday-2014-finalRichard Rodger Enterprise software teams are starting to understand and embrace the
power of Node.js. They face a serious challenge: integrating Node.js
into the legacy systems they maintain, and migrating these system over
time into Node.js architectures. This talk is a pathfinder for those
facing this task. As a community we must proactively engage with the
Java and .Net communities, and create a deeper understanding of the
"Node.js Way".
Micro-services Battle Scars
Micro-services Battle ScarsRichard Rodger This document discusses microservices and some of the benefits and challenges of using a microservices architecture. It notes that microservices involve running many small, independent processes that communicate asynchronously via messages. Services can be developed and deployed independently, allowing for continuous deployment and improved scalability. However, microservices also introduce new challenges around service communication and coordination that require tools and best practices to address.
Rapid Digital Innovation: How Node.js Delivers
Rapid Digital Innovation: How Node.js DeliversRichard Rodger Node.js allows for rapid digital innovation by enabling rapid feedback cycles and using data to guide iterations. It breaks down barriers to innovation by delivering value early. Projects can be delivered in half the time compared to traditional platforms due to Node.js requiring less code and being easier to change. Node.js is also well suited for microservices architectures. A case study described a digital transformation initiative for multiple companies across countries that was delivered using Node.js within a tight 12 week deadline by a small distributed team, despite many challenges.
Richardrodger microxchgio-feb-2015-final
Richardrodger microxchgio-feb-2015-finalRichard Rodger This document discusses measuring microservices by monitoring message flow rates and patterns. It suggests measuring:
- Message flow rates after deploying new services to detect any breaks
- Common message patterns like actor, subscriber, chain, and tree to validate expected behavior
- Invariants like the relationship between add-item and sales-tax messages to ensure the system is functioning correctly
Measuring these things provides visibility into the health and risks of the distributed system.
Building businesspost.ie using Node.js
Building businesspost.ie using Node.jsRichard Rodger This document discusses lessons learned from building JavaScript applications. It finds that client-side JavaScript is very challenging due to the need to support multiple browsers. It recommends using a framework like Backbone.js and keeping business logic in common code. Multi-platform HTML and CSS are also difficult due to varying browser support for CSS3 and media queries. The document notes that app stores present challenges different than websites, like inability to deploy hotfixes. It finds Node.js very capable but callbacks can be tricky. Overall it emphasizes planning for variations in browsers and platforms.
The Software Craftsman
The Software Craftsmangoeran This document discusses the need for software craftsmen and their characterization. It defines a software craftsman as someone who chooses to "get it right" over just "getting it done", takes responsibility for their work, and is a continuous learner. It recommends ways for developers to become craftsmen, such as practicing techniques like TDD, refactoring, and contributing to the community.
The Software Craftsman (2nd edition)
The Software Craftsman (2nd edition)goeran The document discusses the need for "Software Craftsmen" who take pride in their work and continuously hone their skills. A Software Craftsman will choose quality over speed and takes responsibility for their work. The document outlines tips for becoming a Software Craftsman, such as learning techniques like test-driven development, practicing through code katas and dojos, and working on real projects. Software Craftsmen are needed because they avoid producing bad code through deliberate practice and skill development.
Software Craftsmanship @ Ntnu
Software Craftsmanship @ Ntnugoeran The document discusses software craftsmanship and test-driven development (TDD). It notes that software craftsmanship is about raising the bar, taking pride in work, discipline, continuous learning, and deliberate practice. TDD's goal is to write clean code that works, following the Red-Green-Refactor mantra of writing a failing test, making it pass quickly, and refactoring code. The document promotes writing clean code because it is less expensive to maintain and leads to better programmers and productivity.

DevOps and the Future of Information Security
DevOps and the Future of Information SecurityDarin Morris This document discusses how DevOps affects information security. It begins by motivating the talk and explaining that information systems need higher quality and faster delivery. Security is often an afterthought in development. The document then discusses what DevOps truly means, debunking several myths including that it replaces Agile or is incompatible with security and compliance. DevOps is explained as a way of thinking about work that emphasizes team collaboration across development and operations. This enables more efficient risk mitigation and implementation of security principles throughout the software development lifecycle.
Lies Enterprise Architects Tell - Data Day Texas 2018 Keynote 
Lies Enterprise Architects Tell - Data Day Texas 2018 Keynote Gwen (Chen) Shapira The document discusses lies that architects sometimes tell and truths they avoid. It provides examples of six common lies: 1) saying a system is real-time or has big data when it really has specific requirements, 2) claiming a microservices architecture exists when the goal is still to migrate, 3) saying hybrid/multi-cloud architectures don't exist when the architecture is just copy-pasted, 4) using "best of breed" when really using only one of everything, 5) claiming something can't be done at an organization due to its nature when other similar organizations succeeded, and 6) avoiding risk or change by safely interpreting things in a non-threatening way. The document advocates defining responsibilities clearly, embracing change, taking measured
A Gentle introduction to microservices
A Gentle introduction to microservicesGianluca Padovani The document provides a history of microservices, describing how the term originated in the early 2000s and was popularized at a software architecture workshop in 2011. It discusses key concepts of microservices like independent deployability, organizing services around business capabilities, and having each service own its own state and data. The document also covers microservice communication patterns, persistence, deployment considerations, and challenges like testing, monitoring, security, and transactions across services.
React Native: Expectations vs Reality
React Native: Expectations vs RealityKaloyan Kosev I had a chance to be part of a team that started developing a decent size React Native mobile app from scratch. As a developer with a solid React background, I had some expectations at first. During my initial research, everything sounded terrific: performance stats, ease of development, learn-once-use-everywhere, debugging tools, etc. But is everything terrific really?
I'm excited to share my journey about how my expectations met the reality. I'll give my personal opinion about the matureness of the technology, for which use-cases it fits well and for which it doesn't. I'll also try to address the most popular misconceptions about React Native, which front-end developers usually have before they have the chance to actually built something.
Moving to Microservices with the Help of Distributed Traces
Moving to Microservices with the Help of Distributed TracesKP Kaiser Moving away from a monolith to a microservices architecture is a process fraught with hidden challenges. There's legacy code, infrastructure, and organizational processes that all need to change, in order to make the switch successful.
But microservices come with a huge increase in infrastructure complexity. We'll see how distributed traces empower developers to work with greater autonomy, in increasingly complex deployment environments.
devops, platforms and devops platforms
devops, platforms and devops platformsAndrew Shafer This document discusses the evolution of DevOps practices and platforms. It describes how organizations like Amazon and Netflix built platforms to enable continuous delivery of software through automation. These platforms allowed for high velocity software development while keeping promises around availability, reliability and security. The document advocates that organizations adopt cloud native principles of using simple, automated patterns and tooling to build platforms that help teams keep promises around delivering features quickly at scale.

Building Scalable Micro-services with Nodejs
Building Scalable Micro-services with NodejsMichal Juhas Node.js is well-suited for building scalable micro-services as it allows for building single-threaded and event-driven applications. Micro-services break up monolithic functionality into smaller, independently scalable services that communicate through APIs. While micro-services improve scalability, they also multiply lower-level design problems across codebases. Async libraries help flatten asynchronous code and handle promises to deal with asynchronous I/O in a scalable way. Process managers like pm2 allow scaling node.js micro-services across clusters.
Software Process... the good parts
Software Process... the good partsAndrew Shafer This document summarizes Andrew Clay Shafer's talk on software processes. It discusses that Agile processes like Scrum have been oversimplified and lost their original spirit. It promotes focusing on frequent delivery, automated testing, minimizing work in progress, prioritizing quality, and inspecting and adapting processes based on outcomes. Context is important in choosing a process, and processes should promote building software to fulfill a vision rather than just completing tasks. Measuring outcomes and having conversations around user stories are also discussed.
Why software projects fail in 2021?
Why software projects fail in 2021?Orlovsky Consulting GbR The document discusses common issues faced by German companies in software development projects. It notes that initial designs often cannot accommodate new requirements, and hidden cloud costs and inability to react fast enough to changing needs are problems. Many German firms struggle to communicate complexity to clients and lack a skilled workforce. Outdated workflows and lack of proper requirements understanding can cause issues. The document recommends hiring independent contractors, establishing strong feedback loops, separating agile and Kanban workflows, implementing automated testing, and constantly evaluating market and client needs. It warns that outdated software practices can lead to high costs, unstable code, risk of failure and security issues, difficulty finding skilled workers, software deprecation, and potential legal problems.
How Functional Programming Made Me a Better Developer
How Functional Programming Made Me a Better DeveloperCameron Presley With the rise in popularity recently, functional programming has become ""The Next Big Thing"". As of today, there are tons of frameworks and tools that can be used for front-end, back-end, desktop, and mobile development. With that being said, the majority of us are still using object-oriented languages for our day jobs and don't need to learn functional programming, right?
In this talk, I'll walk you through my experiences learning functional programming over the last year, how my style of programming has changed, and how I now think about programming with regards to both functional and object-oriented paradigms.
Open is as Open does
Open is as Open doesAndrew Shafer This document discusses the concept of "open" as it relates to open source software and open cloud computing. It explores different definitions of open, including the four freedoms that define open source. It also addresses questions around who benefits from openness and how business models have evolved around open source. The document encourages questioning assumptions and perspectives on openness.
Code Collaboration With Git & Stash (and Bamboo)
Code Collaboration With Git & Stash (and Bamboo)Sven Peters This document discusses code collaboration using Git and Stash with Bamboo for continuous integration. It promotes using pull requests and branches for code changes with review and approval processes. Simple workflows are shown using pull requests, branches and merges with no specific roles. Additional features discussed include repository permissions, security, and development speed. Custom hooks and addons are presented as ways to further protect code and enforce processes. The overall message is how these tools can help teams code together effectively.
Serverless Architecture
Serverless ArchitectureDirk Weibel The document discusses serverless computing and its implications. It defines serverless computing as deploying small amounts of functionality without concern for server maintenance or scalability. This relies on third parties to manage servers and services. Serverless computing leads to lower costs but more complicated operations, release management, and moving between platforms. Common triggers for serverless functions include program invocation, messages, file creation, APIs, and database events. The document also provides examples of serverless usage patterns and best practices for serverless applications.

Evaluación preliminar de los recursos prospectivos de hidrocarburos convencio...Shale Gas España España es un país poco explorado, pero con gran potencial para generar recursos energéticos propios, tanto en el terreno del gas convencional y no convencional, como en el del petróleo. Así lo confirma el informe presentado por la Asociación Española de Compañías de Investigación, Exploración y Producción de Hidrocarburos y Almacenamiento Subterráneo (ACIEP) en colaboración con GESSAL, compañía española de referencia internacional en la exploración del subsuelo. Según el informe “Evaluación preliminar de los recursos prospectivos de hidrocarburos convencionales y no convencionales en España”, los recursos prospectivos potenciales de gas (convencional y no convencional) en España ascienden a 2.500 BCM (miles de millones de m3 de gas) –en su estimación media-. Esta cantidad equivale a 70 años de consumo en España, tomando como base los estándares de hoy en día. Con la cotización actual del gas, su valor en el mercado alcanzaría los 700.000 millones de euros.

Which Top Programming Languages to Learn in 2024 for High-Demand Tech Jobs_.pdf
Which Top Programming Languages to Learn in 2024 for High-Demand Tech Jobs_.pdfDina G 1. Introduction: The Programming Puzzle of 2024
In 2024, programming isn’t just a skill—it’s a superpower. Think of it as being able to speak the secret language that powers everything from your favorite apps to the robots that might one day replace your barista (don’t worry, we’re not there yet). In a world where tech jobs are hotter than a laptop on your knees after an all-night coding marathon, picking the right programming language is like choosing the right tool for the job.
Imagine this: you're at a job interview for a high-paying tech role. The interviewer asks you, “What languages are you proficient in?” Now, if you casually toss out “Python, JavaScript, and Rust,” you might as well drop the mic because you just became the tech world’s equivalent of a Swiss Army knife. But here’s the deal—there are so many programming languages out there, it can feel like trying to pick a favorite flavor at an ice cream shop that offers 300 options. Spoiler alert: there’s no “right” flavor, but there are definitely some that are way more popular in 2024.
Why does it matter what you learn, though? Aren’t all programming languages the same? Nope. Some are great for building web apps, others are your go-to for AI and data science, and a few are the equivalent of carrying a rusty pocket knife—barely functional and more likely to cause you pain than help. This guide will break down which programming languages are at the top of the pile in 2024 and why learning them could land you that dream job where you get to say things like, “Oh, that’s just an algorithm I designed.” Fancy, right?
So buckle up! Whether you’re a seasoned coder, a tech newbie, or someone who has always thought programming sounds about as fun as doing your taxes, this guide is here to make your journey into the world of programming both useful and fun. We’ll dive into the languages that are leading the charge in the tech world, why they’re important, and how they can help you snag those high-demand tech jobs that everyone’s talking about.
2. Why Programming Languages Matter in 2024: It’s More Than Just Code
Let’s start with a bold statement: programming languages are the heartbeats of the digital world. Without them, your smartphone would be a very expensive paperweight, social media would be non-existent (we’d all be talking to each other in person—gasp!), and your favorite video games would be, well, just board games. The magic of programming is that it transforms ideas into reality, whether that’s an app that helps you order tacos with a single tap or a self-driving car that won’t let you down even when your GPS does.
But why should you care about programming languages in 2024, specifically? Isn’t learning one language enough to get you a job, fame, and fortune? Well, not quite. The world of tech is evolving fast, like Usain Bolt running a sprint after five espressos fast. In 2024, new technologies are emerging, businesses are transforming digitally

Richard_TheDev2023_pattern.pptx.pdf
Richard_TheDev2023_pattern.pptx.pdfRichard Rodger The presentation addresses the challenges developers face with APIs, such as the diversity in authentication methods, SDKs, and the steep learning curve for each new API. The key proposition is to approach API interactions through an ORM-like abstraction, treating APIs as databases to simplify CRUD operations and action commands.
The core idea revolves around treating everything as a message, leveraging microservices as modular, independent components that communicate through these messages. This approach enables a uniform way to interact with various APIs by encapsulating the complexities behind simple, standardized message formats. The example provided illustrates how updating a GitHub repository's description can be abstracted into a message, streamlining the process.
This methodology promotes a component-based architecture where microservices, defined by their ability to handle specific message patterns, can be composed to achieve more complex functionalities. The presentation outlines how this model can be applied to the GitHub API, transforming traditional API calls into message-driven interactions, thereby achieving a higher level of abstraction and simplicity.
The benefits of this approach include a unified interface for API calls, reduction in the reliance on multiple SDKs, and the facilitation of "pure" business logic that focuses on entity manipulation rather than the intricacies of API communication. The presentation concludes with practical considerations for implementation, such as handling logistics and edge cases, and offers resources for further exploration, emphasizing the philosophy of reducing unnecessary complexity in software design.
richard-rodger-awssofia-microservices-2019.pdf
richard-rodger-awssofia-microservices-2019.pdfRichard Rodger This presentation shares the journey of voxgig, a Software-as-a-Service platform for conference exhibitors, and its strategic decision to adopt microservices from the outset. The narrative unfolds with an exploration of how a small, remote team can build a significant platform, detailing a development timeline that spans from initial exploration to platform launch, all structured around microservices.
The architecture of voxgig is dissected to reveal two pivotal tactics: Transport Independence and Pattern Matching, which collectively enable emergent design within the microservices ecosystem. These concepts are expanded to illustrate their role in facilitating service distribution, extension, specialization, and composition, laying the groundwork for a robust microservice architecture.
Despite aspiring to an ideal microservice structure characterized by clean separation between client, application, and core data layers, practical challenges lead to a more organic coding approach, often necessitating later technical debt repayment. The evolution of voxgig's architecture culminates in a diverse ecosystem of 65 Node.js services, enriched by a detailed statistical analysis highlighting service size, age, quality, and the overarching message patterns that constitute the system's backbone.
Key lessons emerge from voxgig's experience, underscoring the complexity of UX design, the importance of adhering to one's methodologies, and the value of investing time in a robust core system. Insights into operational efficiencies, such as service bundling for cost savings and the indispensability of a message REPL, are shared. The presentation concludes by emphasizing the critical role of components within the microservices framework, advocating for system-wide operability in a single process locally and the pragmatic use of synchronous messages for the majority of use cases, all while championing the concept of microservices as fundamental components of a scalable, agile architecture.
richardrodger-microservice-algebra-cluj-apr.pdf
richardrodger-microservice-algebra-cluj-apr.pdfRichard Rodger This presentation delves into the mathematical principles underpinning microservices, drawing inspiration from historical numeral systems to illustrate the significance of adopting efficient mental models in software architecture. By contrasting the complexities of Roman numerals with the streamlined Indian numerical system, the talk sets the stage for rethinking software design through an algebraic lens, where microservices are seen as algebraic functions transforming inputs to outputs, akin to CRUD operations.
The core idea revolves around conceptualizing microservices as operations on messages, ensuring seamless service integration within complex systems through transport independence and pattern matching. This approach fosters a loosely coupled architecture where services communicate based on message content rather than direct identities, enhancing system flexibility and scalability.
Practical examples, including the development of a Node.js module search engine, demonstrate the application of these concepts, showcasing the ease of system expansion and modification when services are designed to interact through a message-driven paradigm. The presentation concludes by underscoring the benefits of this methodology, such as increased system adaptability, easier management of technical debt, and a more granular approach to system evolution, advocating for a shift towards viewing microservices as integral components of a coherent and scalable system architecture.
richardrodger-designing-microservices-london-may.pdf
richardrodger-designing-microservices-london-may.pdfRichard Rodger In this thought-provoking session at mucon London 2018, the dialogue revolves around the foundational premise that microservices should be embraced from the inception of a project, irrespective of the organization's size, from startups to established enterprises. The discussion opens with a candid acknowledgment of the inherent challenges in software engineering across the board, probing into the reasons behind the perceived complexity of software development, our collective penchant for perfection, and the frequent overemphasis on process over product.
The narrative then shifts to a more philosophical perspective, positioning microservices as the optimal intersection of psychological comfort and engineering pragmatism, conceptualized as units of quality, trust, and business logic encapsulation. This conceptual framework underpins a series of tactical recommendations, advocating for a message-centric approach to system design, where the delineation between monoliths, microservices, and serverless architectures blurs in favor of seamless communication and interoperability.
Practical advice is offered on tackling the 'general case' in system design, encouraging the development of specialized services for outlier scenarios and promoting adaptability to change. However, this approach is not without its trade-offs, sparking a debate on the merits and pitfalls of repository strategies and the double-edged sword that is Kubernetes, juxtaposed against the benefits such as finely segmented technical debt, deferred decision-making, and the capacity to scale rapidly without extensive cross-team coordination.
The session concludes on a reflective note, inviting attendees to explore further resources such as senecajs.org and "The Tao of Microservices", leaving the audience with a nuanced understanding of microservices as not just a technological choice, but a strategic framework for building resilient, adaptable, and business-aligned software ecosystems.
richardrodger-designing-microservices-london-may.pdf
richardrodger-designing-microservices-london-may.pdfRichard Rodger This presentation introduces a systematic approach to designing microservices using a visual language, beginning with the identification of requirements and distillation into messages that dictate service interactions. The methodology is illustrated through the process of developing a user registration system, breaking down the requirements into discrete messages like 'register-user' and 'confirm-email', which in turn inform the design of specific services handling registration and email confirmation.
The discussion extends to the temporal and functional dynamics of microservice interactions, differentiating between synchronous and asynchronous, as well as consumed and observed messages, using a unique visual lexicon where hexagons represent microservices, solid and dashed lines denote synchronous and asynchronous communications, and arrow styles distinguish between message consumption and observation.
The narrative further concretizes these concepts by outlining the design of a Node.js module search engine, showcasing how business requirements translate into a network of microservices handling search, indexing, and module detail presentation. The intricate web of service interactions is depicted through the visual language, demonstrating how services like 'web', 'search', 'npm', and 'github' collaborate through well-defined message patterns.
By the conclusion, attendees are equipped with a versatile framework for microservice design, capable of transforming complex system requirements into clear, manageable service components, as exemplified by the 'nodezoo' search engine project. This methodological approach not only clarifies the architecture of microservices systems but also facilitates their scalability, maintainability, and evolution over time.
richardrodger-microservice-risk-dublin-mar.pdf
richardrodger-microservice-risk-dublin-mar.pdfRichard Rodger This presentation delves into the intricate balance of risks and rewards in adopting microservices architecture, drawing parallels between complex systems failures, like the Three Mile Island nuclear incident, and potential pitfalls in software systems. It underscores the inherent risk in systems composed of multiple dependent components, highlighting how increased component count amplifies failure likelihood, challenging the conventional wisdom that redundancy can safeguard against systemic flaws due to homogeneity in components.
The discourse shifts to pragmatic strategies for managing deployment risks in microservices environments, advocating for frequent, low-impact deployments to mitigate the consequences of inevitable errors, as opposed to infrequent, high-stakes updates. The speaker presents microservices as a solution that simplifies deployments by isolating changes to individual components, thereby enhancing system reliability. The emphasis is placed on monitoring message flow rates as vital indicators of system health, with various microservice patterns like Actor, Subscriber, Chain, and Tree explored to illustrate message distribution dynamics.
The presentation concludes with practical deployment strategies like Canary and Progressive Canary releases, along with the concept of "Bake" deployments to incrementally expose new features, using these methods as risk measurement tools within the continuous delivery pipeline. The talk encourages embracing measured, data-driven approaches and automation to navigate the complexities of microservice deployments effectively, ensuring that technology adheres to the unforgiving principles of reality over theoretical perfection.

Title: Rethinking Service Discovery in Microservices Architecture
Description:
This presentation delves into the microservices architectural pattern, emphasizing the importance of service discovery in a landscape where services operate under the illusion of being solitary entities in the system. The discussion begins with an overview of microservices — small, independent processes that communicate through messages, which collectively contribute to a robust component model facilitating rapid development, continuous delivery, and the mitigation of technical debt.
The core of the talk addresses the complexities and unconventional programming models introduced by microservices, particularly focusing on the challenge of service-to-service discovery. Various strategies for service discovery are explored, including the use of configuration files, intelligent load balancing, service registries, DNS, and the necessity of a message bus. The concept of service discovery is then critically examined, proposing a paradigm shift towards pattern matching, where services interact based on message patterns rather than service identities. This approach advocates for transport independence, blind messaging, and a peer-to-peer model, where services maintain a local worldview, updated dynamically as services fluctuate. The presentation concludes by introducing the SWIM algorithm, an infection-style process group membership protocol designed for scalability and weak consistency, exemplified through a practical implementation in a Twitter clone built with 14 microservices.

Richardrodger nodeday-2014-final
Richardrodger nodeday-2014-finalRichard Rodger This talk is an appeal to server-side JavaScript developers to make
use of this time of change - Node.js is going to become the primary
server-side platform for most developers. We can move forward from
the old way of building web apps as large inter-locking co-dependent
code bases.
The Node.js module system has shown us the way. It's the first
step. Now, we need to use the beauty of Node modules to help us build
robust, scalable apps.
This approach is called the Micro-Services Architecture. It's more
than just having some services with HTTP end-points. It's about taking
this to the extreme. Everything is a service, and no service is larger
than 100 lines of code.
We've been using this approach for most of our projects for the last 18
months and it works really well. We get to drop loads of
project management ceremony. There will be some customer war stories.
