How Message Queues Work

Published: 2025-01-25 | Origin: /r/programming

Message queues facilitate asynchronous communication in modern distributed systems by decoupling producers (the services sending messages) from consumers (those processing messages). When a producer wants to send data, it doesn't contact the consumer directly but instead sends a message to a queue, which includes both the payload and metadata. The process allows producers to continue functioning without waiting for consumers to process messages. After a message reaches the message queue broker, it is stored reliably, often using the concept of topics. Topics serve as logical channels for

You could have invented Fenwick trees

Published: 2025-01-25 | Origin: Hacker News

The content discusses the use of Fenwick trees (or binary indexed trees) for efficiently managing a sequence of integers, allowing quick updates and range queries. It begins by contrasting Fenwick trees with segment trees, noting that the former's implementation, while efficient, involves complex bitwise operations on indices. The article emphasizes the operations performed on a sequence of integers, specifically updating a value at a given index and querying the sum over a specified range. It explains that a simple mutable array allows for constant-time updates

AI Coding Is Based on a Faulty Premise

Published: 2025-01-24 | Origin: /r/programming

The author expresses a mix of optimism and concern about the rise of AI in software development. While they utilize AI tools to enhance their coding efficiency, they feel distressed over the trend of replacing human developers, particularly junior ones, with AI. This trend is seen as potentially regressive, with historical context drawn from the software crisis of the 1990s and the evolution towards agile development. In the late 1960s, NATO addressed early challenges in software development through conferences, coining the term

AI is Creating a Generation of Illiterate Programmers

Published: 2025-01-24 | Origin: /r/programming

The author reflects on their experience with coding in the age of AI, particularly following an outage of an AI tool they rely on. They express concern over how their programming skills have deteriorated due to dependency on AI for tasks like documentation reading and debugging. Instead of learning from error messages, they find themselves simply copying and pasting issues for AI to resolve, which diminishes their knowledge and understanding. The author notes a shift in emotional satisfaction, transitioning from joy in solving problems to frustration when AI does not

Wild – A fast linker for Linux

Published: 2025-01-24 | Origin: Hacker News

Wild is a fast linker designed for iterative development on x86-64 Linux. Although it lacks incremental linking at this stage, it is deemed suitable for development purposes. For production, users are advised to use more established linkers like GNU ld or LLD. Installation options include using pre-built binaries or downloading a tarball. For Rust code, users can configure Wild in their `~/.cargo/config.toml`. While Mold is faster, it also doesn't support incremental linking, which is a future goal

How I open-sourced my secret access tokens from GitHub, Slack and NPM and who of them cares about it | Vue & Node admin panel framework

Published: 2025-01-24 | Origin: /r/programming

The content describes a CI pipeline using Woodpecker CI that runs builds, publishes packages to NPM, creates GitHub releases, and sends Slack notifications about releases. Initially, secrets were stored in the CI's internal Vault, but the author decided to switch to Infisical for better centralized secrets management while moving plugins to separate repositories. After exporting secrets to a .vault.env file and successfully running the first build, issues arose when a plugin failed due to an invalid NPM token, which had unexpectedly

Every System is a Log: Avoiding coordination in distributed applications

Published: 2025-01-24 | Origin: /r/programming

The article by Stephan Ewen, Jack Kleeman, and Giselle van Dongen discusses the complexities of building resilient distributed applications. It emphasizes the need for developers to constantly anticipate potential failures, such as service crashes, unavailable APIs, race conditions, and process issues, which leads to a focus on failover strategies, retries, and coordination between various components. Unfortunately, many applications struggle to handle these failures correctly. To alleviate these challenges, the authors propose a radical simplification that involves avoiding distributed coordination.

Two features Typescript will never include

Published: 2025-01-24 | Origin: /r/programming

The article discusses two features that TypeScript does not support: negated types and nominal (or branded) types. Despite being a powerful tool, TypeScript has limitations due to its alignment with Set Theory, which includes operations like Union and Intersection, but lacks support for type subtraction (negated types). For instance, you cannot specify a type like "string - 'click'," although there are workarounds, particularly when using generic function arguments. TypeScript's structural type system focuses on the data's
