This document provides an introduction and overview of Redis. Redis is described as an in-memory non-relational database and data structure server. It is simple to use with no schema or user required. Redis supports a variety of data types including strings, hashes, lists, sets, sorted sets, and more. It is flexible and can be configured for caching, persistence, custom functions, transactions, and publishing/subscribing. Redis is scalable through replication and partitioning. It is widely adopted by companies like GitHub, Instagram, and Twitter for uses like caching, queues, and leaderboards.

10 essentials steps for kafka streaming servicesinovia
This Matters Meetup gives you keys to build event driven microservices with Apache Kafka. In only 30 minutes, Ben Stopford, technologist at Confluent Inc, gives you 10 essential steps to streaming services with Kafka.
Redux scaled at a startup with 20 frontend developers working on 5 apps by:
1) Providing training to standardize Redux implementation.
2) Structuring the codebase into modules with action creators and reducers.
3) Normalizing the state like a database to simplify reducers and use selectors.
Want to migrate to React ? Learn from the experience of Docusign. In this meetup, Joe Cocco, engineering at Docusign provides tips that can help your migration, your road to react. Don’t forget to subscribe http://bit.ly/2EHSdU7
https://matters.tech/
Migrating to React can be a long road. It is always better to have some tips before initiate this process. This Matters Tech video provides talks of two engineers at Docusign. Joe Cocco and Claudiu Andrei explain the steps of a successful React migration, based on their own experience at Docusign.
They give you the keys of success, but they also explain the issues at scale. Some pros and cons of Reactjs are revealed in this Matters Meetup too. If you plan a journey to react, you must watch this video, because maybe you didn’t think of hurdles you will have to surmount, like how to integrating React into existing applications.
However, there is a lot of benefits migrating to React. For instance, the goal of Docusign was to give developers the tool to move forward. The two engineers will convince you to make the transition to this Javascript Library.
This document discusses using NGINX as an API gateway for microservices architectures. It describes how NGINX can provide essential API gateway functions like API routing, authentication, overload protection, and request tracing in a lightweight and efficient manner. The document advocates for separating the roles of a secure proxy and API gateway to handle north-south and east-west traffic respectively. Key API gateway capabilities of NGINX like API routing, authentication using API keys or JWT, and request tracing are demonstrated with code examples.
A transaction ID (TID) is a unique identifier assigned to each request in a distributed system to track and monitor the request. It can be generated algorithmically to ensure uniqueness across the system and must be generated by an API gateway if not already present. While the TID can take different formats as long as it remains unique for a specified time, common examples include a random string of characters or numbers concatenated with relevant context about the request.
Meetic back end redesign - Meetup microservicesinovia
The document discusses Meetic's redesign of its backend architecture from a monolithic system to microservices. Some key points:
- The monolith became unmaintainable and difficult to scale, leading to a plan to split it into microservices
- Over two years, they developed around 30 microservices each focused on a specific functional area
- This improved testability, deployments, and allowed independent teams to work more efficiently
- Challenges included managing dependencies between services and ensuring consistent interfaces
Building a Secure, Performant Network Fabric for Microservice Applicationsinovia
The document discusses building a secure and performant network fabric for microservices applications. It outlines some of the key challenges with microservices including service discovery, load balancing, and secure inter-service communication. It then presents several network architectures and how NGINX can help by providing solutions for service discovery, robust load balancing, fast encryption through persistent SSL connections, and circuit breaking functionality to address issues.
CQRS, or Command Query Responsibility Segregation, is an architectural pattern that separates read and write operations into different interfaces. It divides an application into command and query responsibilities, with different programming models for each. CQRS helps improve scalability and performance by allowing queries and commands to evolve independently.
Domain Driven Design (DDD) is a software development approach that focuses on modeling a domain into conceptual objects and relationships. Key concepts include ubiquitous language to describe the domain, domain models to represent concepts, and bounded contexts to define model boundaries. DDD aims to build software that closely matches how an organization perceives its domain.

Speedrunning involves completing video games as fast as possible. Tool-assisted speedrunning (TAS) uses emulators to play games frame-by-frame with perfect inputs. TAS runs often surpass human speedruns by taking advantage of frame-level manipulation. While TAS removes human error, both speedrunning and TAS aim to entertain and push games to their limits, with TAS defining theoretical limits and speedrunning striving to achieve them.
The document discusses common patterns for asynchronous JavaScript including callbacks, promises, and generators. It provides examples of using callbacks for event handling and avoiding conflicts. It then introduces promises as a better solution than nested callbacks and shows how to chain and wait for multiple promises. Finally, it presents generators as a cleaner way to write asynchronous code that looks synchronous using yield and async/await syntax.
The document provides recommendations for building REST APIs based on the author's experience designing dozens of REST APIs. It covers topics like resources and HTTP verbs, transport, pagination, filtering, authentication, versioning, representations, errors, caching, rate limiting, and consistency. The overall message is to use web standards pragmatically, respect idempotency and safety of HTTP verbs, and make design decisions based on the intended audience of the API.

In today's world, artificial intelligence (AI) is transforming the way we learn. This talk will explore how we can use AI tools to enhance our learning experiences. We will try out some AI tools that can help with planning, practicing, researching etc.
But as we embrace these new technologies, we must also ask ourselves: Are we becoming less capable of thinking for ourselves? Do these tools make us smarter, or do they risk dulling our critical thinking skills? This talk will encourage us to think critically about the role of AI in our education. Together, we will discover how to use AI to support our learning journey while still developing our ability to think critically.

Slides for the presentation I gave at LambdaConf 2025.
In this presentation I address common problems that arise in complex software systems where even subject matter experts struggle to understand what a system is doing and what it's supposed to do.
The core solution presented is defining domain-specific languages (DSLs) that model business rules as data structures rather than imperative code. This approach offers three key benefits:
1. Constraining what operations are possible
2. Keeping documentation aligned with code through automatic generation
3. Making solutions consistent throug different interpreters
