Advent of Code 2024 - Day 23: LAN Party
- Advent of Code 2024 - Day 23: LAN Party
- Today's challenge was rather run, and somewhat simple (or at least Part 1 was).
- Collect all the connections in trios where any of the triangles computers begin with t.
- To achieve this we create a mapping of node -> connections (neighbors).
- On part 2 we need to find the largest set of inter-connected computers.
- The Bron-Kerbosch algorithm is used to find the largest groups (called cliques) in a graph.
- Finding the largest clique by brute force (trying every possible group) is slow for large inputs.
- The Bron-Kerbosch algorithm makes this process faster by:
- Starting with smaller groups (subsets) and expanding them.
- Stopping early when a group can’t grow into a larger clique.

How to Build a Reverse Proxy with Rust and Rama
- This article explains how to build a TLS termination proxy with Rust and Rama, which is a modular service framework for the Rust language to move and transform network packets. For this purpose, the author uses the TLS boring termination example in the Rama repository. A reverse proxy is a server that sits in front of a web server and enhances the performance, security, and reliability of the web server.
- The article provides the code for the HTTP service function of the project, which retrieves the client's address and proxy's address and sends a response to the client acknowledging it. The code demonstrates the configuration of the TLS server with ServerConfig API.
- The article also explains the implementation of middleware layers, including HaProxyClientLayer, HaProxyLayer, and ConsumeErrLayer, for handling TLS connections and logging clients' information in the proxy's terminal. The author also explains how to use task spawning in Rama.
- Finally, the article shows how to create an HTTP server using Rama's HttpServer API and drives home why Rama is a great alternative framework for creating proxy services that use Tokio and Tower. The author particularly highlights the helpfulness of the Rama community in the Discord server and the repository in troubleshooting their issues.
- The author advises that Rama is highly in development, so for now, one should use the main branch to stay up-to-date with the changes in the Rama ecosystem.
- The project's source code is available on GitHub and can be used as reference material for building similar proxies.
- Overall, the article is a great introduction to Rust and Rama for building a reverse proxy that terminates TLS connections.

Armin Ronacher: Reflecting on Life
- Armin Ronacher, writes on his personal blog about his learnings on engineering and life. He shares that fulfillment and happiness come from a commitment to meaningful work, relationships, and personal growth and purpose.
- Putting time into work and skills is always worth it. It's all about progress rather than perfection. Each hour you spend iterating, refining, failing and retrying brings you closer to excellence and in turn makes you enjoy your work.
- The key isn't avoiding hard work but finding meaning in it. Your payout should not just be your happiness in the moment, but it should be long-lasting. If the effort you are putting into something is not reciprocated or the nature of the work feels meaningless, it can eventually get to your health.
- Life isn't about sampling everything but making deliberate choices and committing to the ones that matter. Choose the best option available to you in that moment and commit to it fully. Mastery and fulfillment come not from chasing endless possibilities but from fully embracing the one path you're on and making it your own.
- When it comes to love and marriage, the luckiest thing that happened to Ronacher was to commit to his wife. When you commit to your partner fully you get a lot in the process. It forces you to figure out all the hard things upfront. They committed to a year-long long-distance relationship that changed him profoundly.
- Seeing children grow up is an incredibly moving experience. Ronacher believes that you need to have your marriage and house in order. The most important thing he learned about having children is that you first and foremost need to take care of yourself. Any stress you experience, you will pass on to your children and it will harm them in the process.
- Ronacher's life is about being present and committing to the things that matter. He hopes others find joy, purpose, and the courage to commit fully to their journeys and that his writings have been useful.

Scala in the Boudoir: Lifting the Veil on Opaque Types and Exporting Our Secrets
- Opaque types allow developers to wrap common primitive types, such as Int or String, to ensure that different concepts are not accidentally interchanged.
- They provide a way to hide the logic or data associated with a type, exposing only controlled extension methods and maintaining full control over how the type is used.
- Extension methods for opaque types can be placed in a separate object, allowing for selective importing and isolation from other methods with the same name.
- Exporting extension methods using 'export' keyword brings them into scope and allows them to be called.

Top 10 React js interview questions.
- React is a JavaScript library for building user interfaces.
- The Virtual DOM (Document Object Model) is a representation of the actual DOM in the browser. It enables React to update only the specific parts of a web page that need to change, instead of rewriting the entire page, leading to increased performance.
- React handles updates and rendering through a virtual DOM and component-based architecture. It re-renders only the components that have actually changed efficiently and quickly.
- State and props are both used to store data in a React component, but they serve different purposes and have different characteristics.
- A Higher Order Component (HOC) in React is a function that takes a component and returns a new component with additional props.
- Server-side rendering (SSR) and client-side rendering (CSR) are two different ways of rendering a React application.
- The useEffect hook in React allows developers to perform side effects such as data fetching, subscription, and setting up/cleaning up timers, in functional components.
- React handles events through its event handling system, where event handlers are passed as props to the components. Event handlers are functions that are executed when a specific event occurs.
- Best practices for performance optimization in React include using memoization, avoiding unnecessary re-renders, using lazy loading for components and images, and using the right data structures.
- React handles testing using testing frameworks such as Jest, Mocha, and Enzyme. Jest is a popular testing framework for React applications, while Mocha and Enzyme are also widely used.

Share Zod Validation Schemas Between Repositories
- Sharing Zod schemas between repositories can become challenging in a fragmented environment. This is where Bit comes into the play.
- Bit simplifies the process of sharing Zod schemas across repositories. It allows you to isolate each schema as a Bit component and version schemas independently to manage updates and maintain backward compatibility.
- Benefits of sharing Zod schemas include consistency, reusability, and maintenance; traditional approaches to sharing schemas can become cumbersome to manage as projects scale.
- Install Bit using the CLI with npx and Install Zod as a dependency in your workspace using bit install zod.
- Tag the component with a version and export the component to an access-controlled scope in Bit platform.
- Install the schema in the relevant projects using bit or a standard package manager like npm, pnpm or yarn.
- Use Bit’s web platform to browse schemas, view usage examples, and documentation. Propagate updates to dependent repositories with minimal effort. Collaborate using Bit’s change requests to review and approve updates collaboratively.
- Whether you’re managing a monorepo, polyrepo, or entirely decentralized codebase, Bit offers the tools you need to make your Zod schemas a cornerstone of your development process.
- By treating schemas as composable components, Bit enables efficient collaboration, consistency, and maintainability. Ready to streamline your schema sharing? Start using Bit today and transform how you manage and reuse your Zod schemas!
- Zod schemas are often used to define the shape of data and ensure its integrity. These schemas can validate incoming requests, enforce types in API contracts, or act as a source of truth for both backend and frontend systems
