ReScript 12 introduces a new build system called Rewatch, which replaces the previous system, bsb. This new build system offers intelligent dependency tracking, faster incremental builds, and enhanced support for monorepo workflows. While bsb was effective for single-package projects, it struggled with limitations in monorepo setups, particularly in watch mode, where it only tracked changes within a single package, failing to trigger rebuilds for dependent packages. Additionally, bsb built packages sequentially rather than in parallel

The author expresses concern about the current discourse surrounding the value of computing in low Earth orbit (LEO), emphasizing the need to address the fundamental question: why is computing 250 miles up potentially more valuable than on the surface? They argue that the conversation often jumps to hardware details without properly considering the economic justification, suggesting motivations are driven more by fear of missing out and aesthetic futurism than by well-grounded value propositions. The author, who has a passion for space and technology, critiques the lack of

The content discusses the `module_function` feature in Ruby's Module class, which creates class methods (singleton methods) on a module while also making the original methods private instance methods for any class that includes the module. This allows utility functions within the module to be used as if they were private methods in the class itself when mixed in, without exposing them in the class's public interface. The text illustrates how these markdown utility functions can help in a class such as `Post`, where they can be utilized

This content is a collaboration with Stephen Margheim, who created a course on building quality Rails applications. It discusses the limitations of the traditional `confirm()` prompt for confirmation dialogs in web applications, suggesting that it appears outdated. Instead of relying on extensive JavaScript for creating styled confirmation dialogs, recent browser updates, specifically Invoker Commands in Chrome and Safari, enable developers to create elegant, animated dialogs with minimal coding. For instance, a confirmation dialog for deleting an item can be built using these modern features without

The content describes a performance issue faced when using message queues for inter-process communication (IPC) at high message rates (500K messages per second). The system's CPU usage is significantly impacted due to the overhead from syscall operations related to `mq_send()` and `mq_receive()`, which dominate profiling data, historically leading to 40% CPU utilization. This situation reflects an actual challenge encountered by LinkedIn's Kafka producers, where extensive use of message queues resulted in reduced throughput due to syscall overhead.

The author discusses their experience with the Go programming language, specifically regarding tracking unique values using maps. Initially, they used `map[int]bool` but later considered switching to `map[int]struct{}` due to its zero-sized type, which theoretically saves memory. Despite this change, they observed no decrease in memory consumption in production. They researched the implications of this change and found that since Go 1.24, a new map implementation called Swiss Tables has been introduced, which reportedly uses less memory

The author recently learned about atomic commits after reviewing a pull request, admitting it took them too long to discover the concept. They explain that atomic commits involve making single, cohesive changes in code that can independently pass continuous integration (CI) tests, ensuring that each commit leaves the codebase in a working state. This approach helps others easily understand commit histories without needing to analyze multiple commits together. The author compares the process to saving progress in a video game at logical checkpoints. They mention that their current development

In Part 1, a badge system was created to track progress and award achievements, but it had a significant design flaw: each feature required manual updates to badges, leading to scattered badge logic and reliance on human memory. This resulted in several problems, as the current approach required features to notify the badge system about events like quiz completions or user logins. The proposal is to shift to an event-driven system. In this new approach, the feature code only emits events without needing to manage badge logic

Working quickly has multiple benefits beyond just completing tasks more efficiently. When you work faster, the perceived cost of starting new tasks decreases, making you more likely to take on additional projects. Conversely, slow work can lead to a lack of motivation, as tasks seem too daunting and contribute to a cycle of procrastination. This is true for any to-do list—when items accumulate without being crossed off, it can discourage further additions. This principle also applies to communication, such as email responses; quick replies lead
