Subscriptions are crucial for the sustainability of LWN.net, and subscribing helps support its ongoing content. The `sockaddr` structure is integral to the BSD socket API, serving to hold network connection addresses since its inception. The original format from 1983 includes a field for the address family (like AF_INET for IPv4) and a 14-byte data field for the address, chosen based on existing address formats of the time. However, as new protocols emerged, many required larger address formats that

A new microbenchmark has been released, showing performance insights for various programming languages, noting that Java and Kotlin are fast due to Google's focus on performance, JavaScript performs well among interpreted languages, and Python is slower without optimizations like PyPy. Despite the excitement, the author expresses frustration with how benchmarks are often misunderstood, emphasizing that they are experiments and not definitive measures of performance. They advocate for a scientific approach to understanding benchmarks, critiquing the focus on flashy animations over meaningful analysis. The author

The author reflects on their experience creating Ninja, a popular build system comparable to Make, which they released in 2011. Initially hesitant to share their side project, they now view it as their most successful open source endeavor, despite other projects like Chrome having more users. Ninja has changed hands in management since its inception, and the author feels a sense of completion in their participation. They summarize their key takeaway: while programming discussions often focus on technical issues, the importance of architecture and social dynamics frequently outweigh

The text discusses plans to conduct a memory consumption benchmark for asynchronous programming across various popular programming languages at the end of 2024, building on a comparison from 2023. The benchmark involves launching a set number of concurrent tasks, each waiting 10 seconds, with a focus on using coroutines instead of threads. The author has created two programs in Rust using popular async runtimes—Tokio and Async_std. Other languages included in the benchmark are C#, which features async/await and NativeA

The content discusses a map of the European electrical transmission network, highlighting the connection points where local settlements connect to the grid and nearby power plants generate electricity. An optimisation algorithm is employed to determine the optimal power flow by calculating the appropriate power generation needed over specified time slots and connection points. This algorithm iteratively guesses the production levels of each power plant to ensure total generation meets consumption while minimizing costs. The results of this optimization can be visualized on the map, with data sourced from the pypsa-e

The author shares their experience managing disk space issues with their self-hosted Postgres database on Linode, after acquiring the podcast hosting platform fireside.fm. While investigating a slow query, they discovered that the database was at 87% disk space usage. Unlike managed solutions, self-managed setups offer less visibility into disk space consumption. A conversation with GitHub's Copilot led to identifying the downloads table as the primary culprit for the high disk usage, which held a large number of records from as far

Stimulus is a lightweight framework that enhances existing HTML with various features, including the ability to check the existence of attributes through the existential attribute option across its APIs (targets, classes, values, outlets). It offers lifecycle methods like connect and disconnect, as well as specific target callbacks ([name]TargetConnected and [name]TargetDisconnected) for when targets are connected or disconnected, which is especially useful with Turbo Streams. Attributes can be easily passed to methods using a standard structure (data-[identifier]-

The content discusses the author's exploration of unusual commit IDs on GitHub. They became curious about whether commit IDs might be intentionally altered and discovered the existence of tools, like git-vanity-hash, that can generate "vanity" commit IDs through brute-force methods. However, the author is more interested in naturally occurring unusual commit IDs. Using GitHub's CLI tool, they initially managed to query a limited number of their public commits but eventually wrote a bash script to retrieve all of their approximately

The article critiques the trend among SaaS vendors to place Single Sign-On (SSO) capabilities behind premium pricing tiers, effectively turning a crucial security feature into a costly add-on. As awareness and regulatory requirements for enhanced security grow, SSO has become essential for many organizations to manage user access effectively. However, it has become common for SaaS providers to require customers to pay for higher subscription levels to access basic security features like SSO, two-factor authentication, and password management. This pricing strategy forces

SQL is a powerful tool for handling complex queries, CRUD operations, and ensuring data integrity through constraints. It supports transactions that allow operations to be rolled back. However, SQL can be challenging to integrate with programming languages like JavaScript and Python due to the difference in paradigms, as SQL queries are usually written as strings within the code, complicating composable programming. Object-Relational Mapping (ORM) libraries, such as Hibernate, help address this issue by modeling databases with objects, but they
