The document discusses how human thinking can be influenced by cognitive biases according to Daniel Kahneman's book "Thinking, Fast and Slow". It explores System 1 thinking, which is fast, instinctive, and prone to errors, and System 2 thinking, which is slower and more deliberate. The author provides examples of cognitive biases that can affect software developers, such as the availability heuristic and anchoring bias, and advises engaging System 2 thinking to make better professional decisions through constant learning, collaboration, and applying established processes.

SC 2015: Thinking Fast and Slow with Software Development
In the international bestseller ‘Thinking, Fast and Slow’, Daniel Kahneman explains how we as human beings think and reason, and perhaps surprisingly how our thought processes are often fundamentally flawed and biased. This talk explores the ideas presented in the book in the context of professional software development. As software developers we all like to think that we are highly logical, and make only rational choices, but after reading the book I’m not so sure. Here I’ll share my thinking on thinking. Topics that will be discussed include; the ‘Availability Heuristic’, which can lead developers to choose the ‘latest and greatest’ technology without proper evaluation; ‘Optimistic Bias’ which can blind architects from the ‘unknown unknowns’ within a project; and more!

In the international bestseller Thinking, Fast and Slow, Daniel Kahneman explains how we, as human beings, think and reason and, perhaps surprisingly, how our thought processes are often fundamentally flawed and biased. This session explores the ideas presented in the book in the context of professional software development. Along this journey, the presentation also shares techniques, processes, and models that can help overcome some of the identified limitations of our decision-making abilities. Topics discussed include the “availability heuristic,” which can lead developers to choose the “latest and greatest” technology without proper evaluation; “optimistic bias,” which can blind architects so they can’t see the “unknown unknowns” within a project; and more.

The technology changes required when implementing a microservice-based application are only one part of the equation. The business and organisation will also most likely have to fundamentally change. In an ideal world, this shouldn’t be a problem - what with the rise of agile, lean and DevOps - but this is not always the situation I encounter in my consulting travels. I would like to share some stories of successful (and not so successful) strategies and tactics I have used over the past four years when introducing service-oriented architecture into organisations.
Join me for a whistle-stop tour of the business and people challenges that I have experienced first hand when implementing a greenfield microservice project, and also breaking down a monolith. We’ll look at ‘divided companies’ vs ‘connected companies’, determine the actual impact of conway's law, briefly touch on the lean startup/enterprise mindset, dive into change management without the management double-speak, and look at the lightweight processes needed to ensure the technical success of a microservices implementation.

In an ideal world, this shouldn’t be a problem, what with the rise of agile, lean and DevOps, but in reality this is not always the situation. In this talk we will share some stories of successful (and not so successful) strategies and tactics that we have used when introducing microservices into a variety of organisations over the past four years.
Join us for a whistle-stop tour of the business and people challenges that we have experienced first hand when implementing greenfield microservice projects and also breaking down monoliths. We’ll look at ‘divided companies’ vs ‘connected companies’, determine the actual impact of conway's law, briefly touch on the lean startup/enterprise mindset, dive into change management without the management double-speak, and look at the lightweight processes needed to ensure the technical success of a microservices implementation (e.g. DevOps, CD).
The main lessons we're keen to share are from observations on a couple of microservice transformation projects we have been involved in - some where teams have been cross-functional and aligned around strategic objectives, and some where they haven't. The latter proved much more challenging, as we saw single domain models being created and shared around the codebase, unclear service/context boundaries, and ultimately people tripping over each other.

In this presentation Nic and Daniel will take you through notonthehighstreet.com's journey, the pain, the joy, and the road to the ultimate success of running a hundred million pound ecommerce business on Docker, Mesos and the AWS cloud. Their mission was to break down a monolith, to chip away at it, and constantly deliver business value, all the while without needing a migration big bang that was bigger than the one that created the universe.
Whilst extending and rebuilding the company's core platforms using a microservice pattern would deliver their need for change, it also introduced complexity around deployment and development - hence their need for Docker. They truly believe that without containers they would have failed in their mission, and in fact, adopting Docker has given them so much more than the ability to change. It has given them the ability to scale, to geolocate, to develop in a way they never thought possible, and above all it has given them the ability to transform our business.
They went “All In”, every single line of code for our front and back end systems is running in a container and Nic would love to share the story of how they did it.

JAX London 2016: "Empathy - The hidden ingredient of good software development?"
When I ask fellow developers what they think about empathy, the answer is often “not much”. However, I believe that the skill of empathy, being able to place yourself in another’s position, is crucial to designing, building and operating software at any scale. Join me for a whistle-stop tour of the benefits of empathy, which I learned from working on a large variety of software projects over the past ten years. I will share success stories and battle scars, and suggest practical techniques that you can harness in order to help your team develop empathy.
Thinking fast and slow with software development - Daniel Bryant
The document discusses how human thinking involves two systems - system 1 which is fast, instinctive, and prone to errors, and system 2 which is slower, more deliberate, and reasoned. It provides examples of how cognitive biases from system 1 can negatively impact software development processes if not accounted for. Some recommendations include applying processes and collaboration to engage more deliberate system 2 thinking, regularly reflecting on decisions made, and continuing to learn from experiences and knowledge of others.

When gathering requirements and performing business analysis, it is obvious that the ability to experience from within another user/customer/being's frame of reference is a valuable skill, but the same can be said when writing code. If we follow Martin Fowler’s train of thought where “any fool can write code that a computer can understand. Good programmers write code that humans can understand” we can see that empathy is at the heart of this skill. We could also argue that the rise of “DevOps” is simply both sides of the traditional divide trying to understand each other better. Developing the skill of empathy isn’t necessarily easy, but in this talk I will share my learnings, techniques and tricks for developing more effective software.

Software Development: Thinking, Fast and Slow
The document discusses how cognitive biases and heuristics affect software developers' thinking and decision making. It explores Daniel Kahneman's concepts of System 1 thinking (fast, emotional, instinctive) and System 2 thinking (slower, deliberate, reasoning). Specific biases that can influence developers are then examined, including the availability heuristic (recalling what is memorable), substitution heuristic (replacing complex judgments with easier ones), and anchoring bias (relying too heavily on initial information). The document encourages developers to employ techniques like constant learning, prototyping, and unbiased estimation practices to overcome these cognitive tendencies.

Microservice Summit 2016 "Microservices: The Organisational and People Impact"
Microservices are where it's at. Everything is easier to manage when it's micro, right? Micro code bases (less than 10 LOC), micro containers (less than 10Mb), and micro teams (less than one person???). 'Micro' things may appear to be easier to manage, but there is always a macro context, and working with people and teams is no exception. This talk presents some of the challenges the OpenCredo team have seen when implementing microservices within a range of organisations, and we'll suggest tricks and techniques to help you manage your 'micro' teams and the 'macro' level.
Topics covered include: empathy - because understanding others is at the heart of everything you do; leadership - advice on creating shared understanding, conveying strategy, and developing your team; organisational structure - from Zappos' holocracy to MegaOrg's strict hierarchy, from Spotify's squads, chapters and guilds, to BigCorp's command and control. There is a management style for everybody; and more

BCS 2016 "Intro to Microservices (and the Seven Deadly Sins)"
The 'microservices' architectural style has taken the software development industry by storm over the past two years. Several people are arguing that this is simply classical SOA being rebranded, while others are suggesting that creating loosely-coupled composable services is simply architectural best-practice. Join Daniel for a brief introduction to the topic of microservices, and also a tour of the nastiest sins (anti-patterns) he has seen in his journey as a consultant.
Topics covered include:
* Pride - selfishly ignoring the new requirements for testing
* Envy - introducing inappropriate intimacy within services by creating a shared domain model
* Wrath - failing to deal with the inevitable bad things that occur within a distributed system
* Sloth - composing services in a lazy fashion, which ultimately leads to the creation of a Distributed Monolith
* Lust - embracing the latest and greatest technology without evaluating the operational impact incurred by these choices

Epl feb 2013 trustees and management discussion
Stephen Abram presented to the Edmonton Public Library Trustees on driving innovation, community, success, and scalability. Some key points:
- Expectations around timeliness and access to non-text content will increase as users and communities continue to diversify.
- Search options will expand and single-purpose devices will decline as social media and collaboration become more important.
- Librarians will need to focus more on strategic services rather than organizing knowledge alone. Collections and metadata will increasingly move to the cloud.
- Libraries' core skills are improving questions, learning, and building communities rather than just delivering information.
5 steps to learn what your customers (really) want
This document outlines 5 easy steps to learn what customers really want:
1. Have a plan to identify who to talk to and where to find them before conducting interviews.
2. Pair up for interviews so one person guides the conversation while the other takes notes.
3. Create an open-ended conversation using questions to understand needs and goals rather than leading questions.
4. Show any demos or prototypes at the end of interviews.
5. Continuously share what is being learned through notes, photos, discussions to gather feedback.

ITKonekt 2023: The Busy Platform Engineers Guide to API Gateways
API Gateways are certainly not a new technology, but the way in which they are being deployed, configured, and operated within modern platforms is forcing many of us to rethink our approach. Can we simply lift and shift our existing gateway into the cloud? Is our API gateway GitOps friendly (and does it need to be)? And what about service meshes, CNI, eBPF, and...
Join this talk for a whistle stop tour of modern API gateways, which a focus on deploying and managing this technology within Kubernetes (on which many modern platforms are built):
- Understand why platform engineers should care about API Gateways today
- Learn about API gateways, options, and requirements for modern platforms
- Identify key considerations for migrating to the cloud or building a new platform on Kubernetes
- Understand how cloud native workflows impact the user/developer experience (UX/DX) of an API gateway
- Explore the components of a complete "edge stack" that supports end-to-end development flows

When enterprise organizations adopt microservices, containers, and cloud native development, the technologies and architectures may change, but the fact remains that we all still add the occasional bug to our code. The main challenge you now face is how to perform integration or end-to-end testing without spinning up all of your microservices locally and driving your laptop fans into high speed!
Join me for a tour of your microservices testing options using a series of Java-friendly tools.
- Explore challenges with scaling container-based application development (you can only run so many microservices locally before minikube melts your laptop)
- Learn about effective unit testing with mocks, using TestContainers for dependency testing, and using Telepresence to extend your local testing environment into the cloud
- Understand when to use each type of test and tooling based on your use case and requirements for realism, speed, and practicality
- See how Telepresence can "intercept" or reroute traffic from a specified service in a remote K8s cluster to your local dev machine

Microservice Summit 2016 "Microservices: The Organisational and People Impact"
Microservices are where it's at. Everything is easier to manage when it's micro, right? Micro code bases (less than 10 LOC), micro containers (less than 10Mb), and micro teams (less than one person???). 'Micro' things may appear to be easier to manage, but there is always a macro context, and working with people and teams is no exception. This talk presents some of the challenges the OpenCredo team have seen when implementing microservices within a range of organisations, and we'll suggest tricks and techniques to help you manage your 'micro' teams and the 'macro' level.
Topics covered include: empathy - because understanding others is at the heart of everything you do; leadership - advice on creating shared understanding, conveying strategy, and developing your team; organisational structure - from Zappos' holocracy to MegaOrg's strict hierarchy, from Spotify's squads, chapters and guilds, to BigCorp's command and control. There is a management style for everybody; and more

BCS 2016 "Intro to Microservices (and the Seven Deadly Sins)"
The 'microservices' architectural style has taken the software development industry by storm over the past two years. Several people are arguing that this is simply classical SOA being rebranded, while others are suggesting that creating loosely-coupled composable services is simply architectural best-practice. Join Daniel for a brief introduction to the topic of microservices, and also a tour of the nastiest sins (anti-patterns) he has seen in his journey as a consultant.
Topics covered include:
* Pride - selfishly ignoring the new requirements for testing
* Envy - introducing inappropriate intimacy within services by creating a shared domain model
* Wrath - failing to deal with the inevitable bad things that occur within a distributed system
* Sloth - composing services in a lazy fashion, which ultimately leads to the creation of a Distributed Monolith
* Lust - embracing the latest and greatest technology without evaluating the operational impact incurred by these choices

This was the presentation given at the SkillShare class "Simulating Your Ideas & Designs".
Epl feb 2013 trustees and management discussion
Stephen Abram presented to the Edmonton Public Library Trustees on driving innovation, community, success, and scalability. Some key points:
- Expectations around timeliness and access to non-text content will increase as users and communities continue to diversify.
- Search options will expand and single-purpose devices will decline as social media and collaboration become more important.
- Librarians will need to focus more on strategic services rather than organizing knowledge alone. Collections and metadata will increasingly move to the cloud.
- Libraries' core skills are improving questions, learning, and building communities rather than just delivering information.
5 steps to learn what your customers (really) want
This document outlines 5 easy steps to learn what customers really want:
1. Have a plan to identify who to talk to and where to find them before conducting interviews.
2. Pair up for interviews so one person guides the conversation while the other takes notes.
3. Create an open-ended conversation using questions to understand needs and goals rather than leading questions.
4. Show any demos or prototypes at the end of interviews.
5. Continuously share what is being learned through notes, photos, discussions to gather feedback.
[DevDay2018] Innovation Mindset: How to Think Outside the Box - By: Jolanda T...
Design Thinking for innovation consists of solving problems that are typically ill-defined and solutions are largely unknown. Thinking outside the box is essential to find solutions to these kinds of problems. This presentation describes the best practices for facilitating small teams to think outside the box, based on sharing Design Thinking and “Design Doing” to IT entrepreneurs and IT students.

ITKonekt 2023: The Busy Platform Engineers Guide to API Gateways
API Gateways are certainly not a new technology, but the way in which they are being deployed, configured, and operated within modern platforms is forcing many of us to rethink our approach. Can we simply lift and shift our existing gateway into the cloud? Is our API gateway GitOps friendly (and does it need to be)? And what about service meshes, CNI, eBPF, and...
Join this talk for a whistle stop tour of modern API gateways, which a focus on deploying and managing this technology within Kubernetes (on which many modern platforms are built):
- Understand why platform engineers should care about API Gateways today
- Learn about API gateways, options, and requirements for modern platforms
- Identify key considerations for migrating to the cloud or building a new platform on Kubernetes
- Understand how cloud native workflows impact the user/developer experience (UX/DX) of an API gateway
- Explore the components of a complete "edge stack" that supports end-to-end development flows

When enterprise organizations adopt microservices, containers, and cloud native development, the technologies and architectures may change, but the fact remains that we all still add the occasional bug to our code. The main challenge you now face is how to perform integration or end-to-end testing without spinning up all of your microservices locally and driving your laptop fans into high speed!
Join me for a tour of your microservices testing options using a series of Java-friendly tools.
- Explore challenges with scaling container-based application development (you can only run so many microservices locally before minikube melts your laptop)
- Learn about effective unit testing with mocks, using TestContainers for dependency testing, and using Telepresence to extend your local testing environment into the cloud
- Understand when to use each type of test and tooling based on your use case and requirements for realism, speed, and practicality
- See how Telepresence can "intercept" or reroute traffic from a specified service in a remote K8s cluster to your local dev machine

DevRelCon 2022: "Is Product Led Growth (PLG) the “DevOps” of the DevRel World"
Over the last year, the Ambassador Labs team has doubled down on their adoption of Product Led Growth (PLG), a growth model where product usage drives customer acquisition, retention, and expansion. It’s been an interesting journey for the DevRel team, who have found themselves working more closely with both the sales and growth engineering teams.
In their quest to reduce the friction of product adoption, they’re thinking more and more about the end-to-end experiences, experimentation, instrumentation, data analysis, and handoffs — much like we saw in the software development world with the adoption of DevOps breaking down barriers between engineering and operations.
The Ambassador Labs team have learned more about the value of creating hypotheses and analyzing quantitative data, but have also been reminded that there is no substitute for qualitative data and engaging human-to-human. Join Daniel for a whistle-stop tour of PLG through the DevRel lens:
– Understand how moving to PLG can impact devrel teams and the work they do: for better and worse!
– Explore how DevRel tooling and community platforms are increasingly overlapping with PLG marketer tooling
– Learn how to structure your goals, common languages, and teams for successfully adopting PLG
Fall 22: "From Kubernetes to PaaS to... err, what's next"
Developers building applications on Kubernetes today are being asked to not just code applications -- they are also responsible for shipping and running their applications, too. We often talk about needing a Kubernetes platform, but are we really looking for a PaaS? Or instead, are we looking for some kind of developer control plane with a Goldilock-sized collection of tools that provides just the right amount of platform? This talk will look back on my experience of building platforms, both as an end-user and now as part of an organization helping our customers do the same. We’ll wrap this talk with a walk-through of the CNCF ecosystem through the developer control plane lens, and look at what’s next in the future of this important emerging category.
Building Microservice Systems Without Cooking Your Laptop: Going “Remocal” wi...
Join me for a tour of coding, testing, and shipping microservices using remote-to-local “remocal” tools and techniques. You will:
- Understand the challenges with scaling container-based application development – i.e. you can only run so many microservices locally before minikube melts your laptop.
- Learn when to use various types of development practices and tooling based on your use case and requirements for production realism, speed, and practicality.
- Explore how to utilize containerized dependencies and Docker for testing, including for both apps and services you own and those you don’t.
- Learn how Telepresence can enable “remocal” development, expanding your local machine and Docker Desktop out into a remote Kubernetes cluster.

Many organizations adopt cloud native development practices with the goal of shipping features faster. The technologies and architectures may change when we move to the cloud, but the fact remains that we all still add the occasional bug to our code.
The challenge here is that many of your existing local debugging tools and practices can’t be used when everything is running in a container or deployed onto Kubernetes running in the cloud. This is where the open source Telepresence tool can help.
Join Daniel to learn about:
- Quick overview of remote-local ("remocal") options and tooling e.g. “kubectl port-forward”, Skaffold, ksync, Telepresence etc.
- An exploration of how Telepresence can “intercept” or reroute traffic from a specified service in a remote K8s cluster to your local dev machine
-- The benefits of getting a “hot reload” fast feedback loop between applications being developed locally and apps running in the remote environment

The main challenge you now face is how to perform integration or end-to-end testing without spinning up all of your microservices locally and driving your laptop fans into high speed! Join me for a tour of testing microservices using a series of Java applications as a case study.
You will learn everything about effective unit testing with mocks, using TestContainers for dependency testing, and using Telepresence to extend your local testing environment into the cloud. Learn when to use each type of test and tooling based on your use case and requirements for realism, speed, and practicality. We will discuss how to utilize containerized dependencies and Docker for testing, including both apps and services you own and those you don’t. We’ll also go over the challenges with scaling container-based application development (you can only run so many microservices locally before minikube melts your laptop). Finally, you’ll see how Telepresence can "intercept" or reroute traffic from a specified service in a remote K8s cluster to your local dev machine.
CloudBuilders 2022: "The Past, Present, and Future of Cloud Native API Gateways"
The document discusses the evolution of API gateways driven by changes in application architecture and technology. It describes how API gateways evolved from hardware load balancers to software load balancers to application delivery controllers to first-generation API management platforms as applications moved to the cloud and adopted microservices. Managing APIs and microservices at the edge with Kubernetes poses new challenges around scaling edge management and supporting diverse requirements. The document outlines three strategies for managing APIs at the edge with Kubernetes and concludes that choosing an API gateway intentionally is important when adopting cloud-native technologies and platforms.
KubeCon EU 2022: From Kubernetes to PaaS to Err What's Next
Developers building applications on Kubernetes today are being asked to not just code applications -- they are also responsible for shipping and running their applications, too. We often talk about needing a Kubernetes platform, but are we really looking for a PaaS? Or instead, are we looking for some kind of developer control plane with a Goldilock-sized collection of tools that provides just the right amount of platform? This talk will look back on my experience of building platforms, both as an end-user and now as part of an organization helping our customers do the same. The key takeaways are:
- Treat platform as a product
- Realize that you can’t have good developer experience (DevEx) without good UX
- Focus on workflows and tooling interoperability
We’ll wrap this talk with a walk-through of the CNCF ecosystem through the developer control plane lens, and look at what’s next in the future of this important emerging category.

DevXDay KubeCon NA 2021: "From Kubernetes to PaaS to Developer Control Planes"
Developers building applications on Kubernetes today are being asked to not just develop applications -- they are also responsible for releasing and running their applications, too. In this talk, we’ll discuss the secular shift towards what Netflix calls “Full Cycle Development” or what Google calls “Service Ownership”. With developers managing so much of the cloud-native development loop, a new class of infrastructure has emerged -- the developer control plane. We’ll explore the evolution from Kubernetes to PaaS, to the developer control planes in use today. We’ll draw on our personal experiences and podcast chats with the larger CNCF community, and discuss real-world examples of developer control planes used at New Relic, Spotify, InVision, and Twitter. We’ll wrap this talk with a walk through of the CNCF ecosystem through the developer control plane lens, and look at what’s next in the future of this important emerging category.

At a previous JAX event I talked about effective cloud native Java developer workflow. Two years later and many new developer technologies have come and gone, but I still hear daily from cloud developers about the pain and friction associated with building, debugging, and deploying to the cloud. In this talk I’ll share my latest learning on how to bring the fun and productivity back into delivering Kubernetes-based software.
Join this talk to:
Learn why the core tenets of continuous delivery — speed and safety — must be considered in all parts of the cloud native SDLC
Explore how cloud native coding benefits from thinking separately about the inner development loop, continuous integration, continuous deployment, observability, and analysis
Understand how cloud native best practices and tooling fit together. Learn about artifact syncing (e.g. Skaffold), dev environment bridging (e.g. Telepresence), GitOps (e.g. Argo), and observability-focused monitoring (e.g. Prometheus, Jaeger)
Explore the importance of cultivating an effective cloud platform and associated team of experts

By Daniel Bryant, Ambassador Labs We all need to be able to get user traffic into our applications, and your requirements for services running on Kubernetes are no different. "But", I hear you say, "what about the K8s Ingress spec? And how do I observe what's happening under the hood? And who should be responsible for configuring the gateway: dev or ops?" These are all good questions! Join me for a whistle-stop tour of all things emissary-ingress, where we will explore how this new edition to the family of CNCF incubation projects can make your life easier when it comes to routing, observability, and integration into the bigger (people and technology) picture.
MJC 2021: "Debugging Java Microservices Running on Kubernetes with Telepresence"
The document discusses using Telepresence to improve the development workflow for Java microservices running on Kubernetes. Telepresence allows developers to run their code locally while still connecting to the Kubernetes cluster, improving the speed of the inner development loop. It supports various workflows from small to large systems. The benefits of Telepresence include using local tools, connecting to cloud resources, and a very fast inner loop. It is an open source project maintained by the CNCF.

Operating System Used by Users in day-to-day life.pptx
Dive into the realm of operating systems (OS) with Pravash Chandra Das, a seasoned Digital Forensic Analyst, as your guide. 🚀 This comprehensive presentation illuminates the core concepts, types, and evolution of OS, essential for understanding modern computing landscapes.
Beginning with the foundational definition, Das clarifies the pivotal role of OS as system software orchestrating hardware resources, software applications, and user interactions. Through succinct descriptions, he delineates the diverse types of OS, from single-user, single-task environments like early MS-DOS iterations, to multi-user, multi-tasking systems exemplified by modern Linux distributions.
Crucial components like the kernel and shell are dissected, highlighting their indispensable functions in resource management and user interface interaction. Das elucidates how the kernel acts as the central nervous system, orchestrating process scheduling, memory allocation, and device management. Meanwhile, the shell serves as the gateway for user commands, bridging the gap between human input and machine execution. 💻
The narrative then shifts to a captivating exploration of prominent desktop OSs, Windows, macOS, and Linux. Windows, with its globally ubiquitous presence and user-friendly interface, emerges as a cornerstone in personal computing history. macOS, lauded for its sleek design and seamless integration with Apple's ecosystem, stands as a beacon of stability and creativity. Linux, an open-source marvel, offers unparalleled flexibility and security, revolutionizing the computing landscape. 🖥️
Moving to the realm of mobile devices, Das unravels the dominance of Android and iOS. Android's open-source ethos fosters a vibrant ecosystem of customization and innovation, while iOS boasts a seamless user experience and robust security infrastructure. Meanwhile, discontinued platforms like Symbian and Palm OS evoke nostalgia for their pioneering roles in the smartphone revolution.
The journey concludes with a reflection on the ever-evolving landscape of OS, underscored by the emergence of real-time operating systems (RTOS) and the persistent quest for innovation and efficiency. As technology continues to shape our world, understanding the foundations and evolution of operating systems remains paramount. Join Pravash Chandra Das on this illuminating journey through the heart of computing. 🌟
