Dealing with dependencies in tests
This document discusses different types of test doubles (fakes, stubs, mocks, spies, and dummies) that can be used to deal with dependencies in tests. It explains what each type is and provides examples of when each might be used. It also discusses how to design code for better test isolation by reducing coupling and avoiding tightly binding components together, though this can sometimes make the code harder to test. Cross-cutting concerns like authentication are discussed as things that may be difficult to fully isolate or mock at a component level.
Organization_GTD
This document provides tips and techniques for improving productivity and agenda management. It recommends booking dedicated time for important tasks, using a todo list app to track tasks, learning to delegate effectively while maintaining oversight, using email or other tools to track delegated items, and demanding clarity, context and objectivity in communications. It also suggests learning when to be flexible with changes and when to say no, and cultivating a growth mindset with daily improvements and repetition of productivity habits.
Thoughts about Shape Up
This document discusses the Shape Up methodology for agile software development projects. It introduces Shape Up as similar to Dual Track Agile, with an initial 6-week discovery process. Key aspects of how shaping works include setting boundaries, roughing out elements, addressing risks, writing a pitch, and creating simple breadboarding prototypes. Other topics covered are cutting scope, how the pitch works, using betting tables instead of backlogs, dealing with bugs, and making progress on the whole stack through scope mapping and discovery charts.
Lean: Principles & Mindsets
Lean is based on several principles and mindsets:
1) Lean focuses on eliminating waste and only doing things that add value.
2) It encourages questioning whether processes, tasks, and activities truly make sense and are necessary rather than relying on preset answers.
3) Lean involves identifying waste and tradeoffs, understanding why certain steps are taken, and continuously improving and adapting processes and structures to better meet goals.
Google guice
Google Guice is a lightweight Java dependency injection framework created by Google. It uses Java annotations and code for configuration rather than XML. Guice supports features like @Inject, @Named, @Qualifier, @Scope, @Singleton and @Provider annotations. It has less functionality than Spring but supports Java 8 and JSR 330. The document includes sample code for a billing service module and payment class using Guice dependency injection. It also provides a link to more Guice features in the GitHub wiki and proposes a coding exercise to create a pet store application using Guice.
NoSQL
This document profiles Diego Pacheco and summarizes information about Redis and Cassandra. Regarding Redis, it outlines that Redis is an in-memory key-value store written in C that is fast, robust, and supports data structures like strings, sets, sorted sets, hashes and lists. It can be used for caching, queues, primary data, and real-time analytics. For Cassandra, it notes that it is a column-oriented NoSQL database created by Facebook, inspired by Dynamo, written in Java, and focuses on availability and eventual consistency over strong consistency.
Architecture & Engineering : Doing the non-obvious!
Diego Pacheco is a software architect, agile coach, and speaker who focuses on non-traditional approaches. Some of his views include that requirements can change and duplication is okay, tests don't always improve design or find bugs, and complexity sometimes needs abstractions but other times they add unnecessary complexity. He also believes teams will always have technical debt so it's important to prioritize fixing quick wins over deep technical issues, and that architecture is about people and enabling teams.
Reflections on SCM
Reflections on SCM: DevOps, CI/CD, Branches, Architecture, PRs, and many more considerations and thoughts.

Some potential solutions proposed include using contracts and mocks between teams, restructuring code using domain-driven design principles, and creating lean shared libraries to reduce duplication while allowing independence. The document advocates for moderate approaches between extremes rather than ignoring problems with dependencies.
I will NOT attend your meeting - I'm an Open Source person
The document discusses the inefficiency of meetings from the perspective of an open source person. It notes that meetings can waste half a day for makers and creators, while being just another slot for managers. It then lists different types of failed meetings and questions whether recurring scheduled meetings are useful. The document acknowledges that brainstorming, vision, and teamwork meetings with clear goals can be valuable when the results are captured. It concludes by stating the author will not attend a meeting if it has no clear goals, has too many attendees, they cannot prepare for it, it is the wrong audience, or the issue can be better solved online.

Getting started with go - Florin Patan - Codemotion Milan 2016
This talk focuses on people which are interested the Go programming language and want to learn it. In it I will present the various resources new gophers have to learn Go, what are the usual pitfalls and how to get help when they are stuck.
Software Design Notes
This document contains software design notes and principles from Diego Pacheco. Some key points include:
- Modules should be designed to be deep with simple interfaces. Classes should also be designed to be deep modules.
- Interfaces that resemble implementations indicate shallow design that leaks information and creates poor abstractions.
- Comments should describe how to use interfaces, not implementation details, and need to stay close to the code.
- Code should be designed to be obvious through use of precise names, patterns, and avoidance of obscurity through event-driven code or generic objects.
- Composition should be used over inheritance in object-oriented design. Patterns also risk over-application.
Lean Startup
Lean Startup refers to applying Lean principles to startups to reduce waste. Traditional business plans and lengthy product development processes are seen as wasteful. Instead, startups should continuously build minimum viable products, test hypotheses, and iterate quickly based on customer feedback to discover what customers want. This approach requires a different culture, processes, structure, and mindset than traditional corporations in order to innovate effectively.

Naming Things Book : Simple Book Review!
The document discusses principles for naming identifiers in code such as variables, classes, and functions. It notes that naming is important because identifiers make up 70% of code and influence comprehension, recall, and bug fixing time. Good naming follows principles like understandability, using names that describe concepts, and consistency. It provides specific rules for naming classes, variables, functions for conciseness, consistency, and distinguishability. The goal is to use names that are understandable to both current and future engineers working on the code.
Continuous Discovery Habits Book Review.pdf
This document summarizes key points from the book "Continuous Discovery Habits" by Diego Pacheco. It advocates for continuous discovery through an outcome-oriented and customer-centric mindset. Discovery requires the collaboration of product managers, designers, and engineers to iteratively test assumptions and validate ideas with customers. The goal is to ensure teams are creating value for users and addressing their needs, pain points, and desires on an ongoing basis through experimental and visual approaches.
Holacracy
This document discusses Holacracy, an alternative organizational structure to traditional hierarchies. It notes that current management structures were designed for factories, while Holacracy is designed for humans. Holacracy eliminates hierarchies and instead focuses on clearly defined roles and circles within an organization. It aims to embrace autonomy through separating people from roles and having roles, not managers, make decisions. While challenging to implement due to issues of power, some companies have adopted aspects of Holacracy.
Encryption Deep Dive
Encryption Deep Dive: Randomness, Entropy, RNG, PRNG, AES, AES Operational Modes, Data Rotations, Java Encryption APIs, Tradeoffs, challenges, Envelope Encryption, KMS, and much more on all things encryption.
Sec 101
This document profiles Diego Pacheco and provides an overview of key software security principles including defense in depth, the least privilege principle, encryption, TLS and mTLS, misconfiguration and error handling, input sanitization, cross-site scripting (XSS), insecure serialization/deserialization, known vulnerabilities, logging and audit trails, threat analysis, and engineering friction. The document emphasizes applying security best practices to protect customer experience, brand integrity, and compliance while avoiding friction for engineering teams.
Management: Doing the non-obvious! III
This document discusses various management concepts and techniques, including:
- Biases that can negatively impact decision-making like planning fallacy and availability bias.
- How work is becoming indistinguishable from sabotage due to bureaucracy and predictability.
- The importance of having "skin in the game" and being willing to be wrong to drive change and learning.
- Dealing with scarcity by identifying high and low performance areas and reallocating resources accordingly.
Management doing the non-obvious II
This document discusses various management concepts and principles:
- You cannot regulate failure in complex systems and it is better to focus on recovering from failures rather than trying to predict and prevent them.
- Product teams are more effective than feature teams because they are focused on discovering customer needs rather than having predefined solutions.
- Sharing a vision rather than a detailed roadmap allows for more flexibility and ability to change tactics.
- Psychological safety and an environment where people feel included, safe to learn and contribute, and safe to challenge the status quo is important for teams.
- Discipline is needed to successfully execute digital transformations but often lacks longevity and focus shifts to short term goals.
Testing in production
The document discusses testing in production environments using "dark canaries". Dark canaries involve deploying code changes to a small percentage of real users without their knowledge to test for issues before broad deployment. The key benefits are that it allows testing with real users and traffic in the actual production environment and catching problems early before they affect everyone. Some challenges are potential privacy issues if users are not informed and ensuring changes don't negatively impact the small group of unaware users.
Nine lies about work
The document outlines 9 common lies about work and proposes alternative truths. The lies discussed include that people care most about the company they work for rather than their team, that the best plan wins rather than intelligence in real-time, and that feedback and performance reviews can reliably rate people. The author argues that people primarily care about their team, intelligence is needed to adapt to a dynamic world, and that reviews mostly reflect raters rather than ratees. The truths proposed emphasize caring for one's team, prioritizing real-time intelligence over static plans, and that people can best rate their own experiences.
Management: doing the nonobvious!
This document provides advice and perspectives on management and leadership from Diego Pacheco. Some of the key points discussed include:
- Ego can distort reality and inhibit innovation, so leaders should suppress ego with humility.
- Not all communication needs to happen between all people; structured teams are better models than rigid organization charts.
- Feedback is difficult to give and receive but is important for growth if approached without emotion or defensiveness.
- Scenario modeling and role playing exercises can help train leaders by anticipating problems before they occur.
AI and the Future
The document discusses several topics related to artificial intelligence and the future, including:
1) Whether AI-generated music has soul or not.
2) The possibility of AI judges making faster parallel decisions.
3) Elon Musk's view that we are all already cyborgs.
4) Musk's proposal that augmented humans could regenerate organs and tissues by 2100 through technologies like neuralink.
5) The potential to reengineer humans and expand lifespans to 120-150 years through these technologies.
Hardening
This document discusses various types of software testing and their purposes. It covers unit testing, snapshot testing, property-based testing, contract testing, mutation testing, stress/load testing, chaos testing, and testing for different environments including backend, frontend, and cloud-native applications. The key points made are that different types of testing are needed to have confidence a solution works, catch regressions, avoid breaking consumers, ensure survivability of failures, and build the right product. Testing approaches must evolve with architectural changes like moving to the cloud. Isolation is important for hardening production systems.
Design 101
This document discusses design principles and best practices for software architecture. It recommends considering use cases, constraints, tradeoffs, and principles like testability, maintainability and flexibility when designing systems. Design is an ongoing process that requires reviewing solutions to identify gaps and fix issues early. Well-documented design specifications can outline business needs, principles, tradeoffs considered, and observability goals to help guide implementation.
Sidecars
The document discusses sidecars and how they can be used to distribute software. Sidecars allow decoupling and isolation by running auxiliary software alongside the main application. They provide benefits like reuse, upgrades/deploys independently, and avoid massive migrations when changing libraries. However, sidecars also introduce deployment complexity and potential performance overhead. They are best suited for scenarios where extreme performance isn't required and decoupling is important, such as when using containers and service meshes.
Architecture 101: Vision, Properties and Skills
Diego Pacheco is a software architecture expert who is the head of software architecture at Cat's Father and an agile coach. He specializes in SOA/microservices, DevOps, and is an author and speaker. The document discusses that software architecture involves making important design decisions that involve trade-offs. It is about structuring teams for scalability and achieving desired properties like isolation, changeability, abstraction and more. The intangible architectural decisions can lead to real problems like cost increases, slowness and downtime if not addressed properly.
The Death of Microservices
The document discusses the death of microservices as an architecture style. It argues that many systems labeled as microservices are actually distributed monoliths due to issues like shared libraries, drivers, frameworks, and tables that couple services together and prevent independent upgrades. It recommends isolating services by avoiding shared dependencies, using packages to separate concerns, and isolating data stores, configurations, and implementations between services. Platforms, education around service-oriented architecture principles, and accepting necessary duplication can help build true microservice systems.
SRE 101
This document provides an introduction to Site Reliability Engineering (SRE). It lists the credentials and background of Diego Pacheco, including his roles as a cat's father, principal software architect, agile coach, and expert in SOA/microservices, DevOps, and observability. The document then defines SRE as "what happens when you ask a software engineer to design an operations function" and outlines some key aspects of SRE culture, including MTTD, MTTR, error budgets, jitter retries, exponential back-off, the "You build it you run it" mindset, and production readiness.
Making sense of streaming
Streaming processes data continuously as it arrives, allowing for real-time analysis and response. Common streaming technologies include Apache Kafka for messaging, Apache Storm and Apache Flink for stream processing, and Apache Spark for both batch and stream processing. While Spark and Flink can handle both batch and stream workloads, Flink has emerged as the leading stream processor due to high throughput and exactly-once processing semantics.
SOA.2020
This document discusses Service Oriented Architecture (SOA) and related concepts like APIs and microservices. It provides an overview of SOA and notes its focus on services, abstraction, interoperability, and flexibility. APIs are discussed as being focused on REST and JSON for external use cases, while microservices emphasize isolation, anti-fragility, and scalability but at the cost of infrastructure complexity. The document poses exercises around designing a banking system using SOA modeling and architecture.
