The content discusses the challenges of debugging mutable data, illustrated by a bug where the last_modified date of entities was consistently one day off. The issue stemmed from using a mutable DateTime object, where changes to the `$now` variable also affected `$entity->lastModified` due to both pointing to the same object. If a DateTimeImmutable object had been used, it would have returned a new instance without altering the original, thereby preventing the bug. The author emphasizes the advantages of immutable objects over

The content discusses the relationship between streaming pipelines and programming language compilers, emphasizing a fundamental principle of separation between declaration and execution. While a streaming pipeline may appear like a simple order processing system, it actually creates a description of intended operations. A compiler then optimizes this description into executable code tailored for specific environments. This principle is important in programming languages like C, where the compiler optimizes operations beyond a straightforward translation. The text highlights JavaScript's ecosystem, noting that Node.js utilizes efficient streams, which

The main argument is that many application failures stem from impossible states in the model rather than complex algorithms. Examples of these nonsensical states include "a user without an email but verified" or "an order that is both shipped and cancelled." To combat this, typed functional programming languages like Elm, Haskell, and F# provide a means to define domain rules directly within their type systems, allowing the compiler to prevent the creation of these impossible states from the outset. Scott Wlaschin’s concept of

The article discusses P2, a new HTML templating library for Ruby that stands out by compiling template source code into efficient Ruby code for generating HTML. Unlike traditional templating approaches, where the code runs directly, P2 treats the code as a description, which is then compiled and executed. While other Ruby gems like Phlex, Papercraft, and Ruby2html offer similar functionality, P2 is noted as the first to implement this technique exclusively. The author explains performance enhancements made to P2

The author attributes their good handwriting not to their Catholic school education but to their engineer mother, whose perfect print and cursive inspired them as a child. However, as an adult reporter, they note that speed has become more important than neatness in note-taking, and handwriting skills are diminishing due to reliance on keyboards and technology. The shift from handwriting to typing in schools has been accelerated by the rise of digital devices, leading some to believe that handwriting is on the decline. Despite this, the author argues

The flow library facilitates a clear separation between application logic and deployment concerns, such as topology, execution, and error handling. It allows developers to provide logic through step functions (step-fns), which are managed as processes by the flow system. Step-fns operate in a loop and do not directly access channels or hold state, making them easy to test and reuse. Step-fns have four key components: 1. **Describe Arity**: Returns a static description of the step-fn's parameters

The author highlights ongoing issues with the installation of Ruby gems, which have persisted for 15 years due to a default configuration that installs gems into system directories instead of users' home directories. This misconfiguration leads to errors during operations like running `bundler install`. Proposed fixes have often been ineffective, particularly issue 5682, which the author criticizes for lacking understanding of the underlying code. The problem stems from a lack of cohesion within the RubyGems project, which includes both the gem and bund

Anti-cheat engines are increasingly requiring players to enable Secure Boot and firmware TPM (Trusted Platform Module) to participate in online multiplayer games, with the goal of reducing cheating. Electronic Arts has mandated these requirements for its upcoming game, Battlefield 6, and Riot’s Vanguard is expected to adopt similar measures as support for Windows 10 ends. These hardware and firmware features have been optional for installing Windows 11, and their requirement is viewed by some gaming communities as an overreach or an attempt to push players

In a post by Max Rozen, he emphasizes the importance of taking action in building projects rather than getting bogged down by the selection of programming languages, frameworks, or tools. He encourages developers to simply build and ship their ideas, acknowledging the possibility of mistakes that can be fixed later. Rozen reflects on his own experience over four and a half years working on a product previously deemed unscalable or unviable, which turned out to be viable despite doubts. He advises that when starting a
