But MDN actually says “fulfills when all of the input's promises settle”. Different verb, different semantics. A human might not catch this. But a tool...Alexandre Gomes GaigalasThe Universal Plug: Connecting Containers to Callablestag:alganet.github.io,2025:2026-03-23-20-The-Universal-Plug--Connecting-Containers-to-Callables2026-03-23T20:00:00Z PSR-11 solved an important problem in PHP: it gave us a universal socket for dependency containers. Any framework, any library, any application can expose its services through ContainerInterface, and any consumer can pull from it without caring about the...Alexandre Gomes GaigalasFeng Shui Refactoringtag:alganet.github.io,2025:2026-03-12-20-Feng-Shui-Refactoring2026-03-12T20:00:00Z If you've worked on a large codebase long enough, you've probably seen a certain kind of refactoring that feels productive but doesn't actually improve the system. Some files get renamed, functions move around, directories and namespaces are reorganized, but nothing...Alexandre Gomes GaigalasLeveraging Attributes With Respect\Validation and Laraveltag:alganet.github.io,2025:2026-02-22-23-Leveraging-Attributes-With-Respect-Validation-and-Laravel2026-02-22T23:00:00Z The full example for this blog post is available on GitHub. Validation logic often ends up distributed across request rules, controller checks, model helpers, and serializers. In that arrangement, constraints for the same field can diverge over...Alexandre Gomes GaigalasBootstrapping Is Not Security Paranoiatag:alganet.github.io,2025:2026-02-22-15-Bootstrapping-Is-Not-Security-Paranoia2026-02-22T15:00:00Z Bootstrapping compilers are often discussed from the same angle: security paranoia. In this framing, their only purpose is to defend against the class of attacks described in Ken Thompson’s Reflections on Trusting Trust. If a compiler is compromised, it can perpetuate that compromise indefinitely, even when its source code appears...Alexandre Gomes GaigalasBuilding a Modular Application with apywire and starlettetag:alganet.github.io,2025:2026-02-12-22-Building-a-Modular-Application-with-apywire-and-starlette2026-02-12T22:00:00Z This blog post explains how to use apywire to build a modular, dependency-injected starlette application. We’ll go step-by-step to wire up services, handlers, and a database using a declarative config.yaml. The complete code for this tutorial is available at...Alexandre Gomes GaigalasValidating Markdown Structure in a Single Declarative Expressiontag:alganet.github.io,2025:2026-02-11-02-Validating-Markdown-Structure-in-a-Single-Declarative-Expression2026-02-11T02:00:00Z Back in 2010, I started this little project called Respect\Validation. At first glance, it's a cute little library that uses fluent interfaces to validate simple values: However, that's just the tip of the iceberg of what this library can actually...Alexandre Gomes GaigalasThe Five Levels of PHP 8.5 Pipestag:alganet.github.io,2025:2026-01-22-11-The-Five-Levels-of-PHP-8-5-Pipes2026-01-22T11:00:00Z PHP's pipe operator unlocks a very readable, functional style. Below I walk through five conceptual "levels" of using You can use these as templates that you can extend upon in your own projects. Each step transforms the value in sequence, like a factory conveyor...Alexandre Gomes GaigalasHow To Make Good Code Reviewstag:alganet.github.io,2025:2026-01-19-14-How-To-Make-Good-Code-Reviews2026-01-19T14:00:00Z Good code reviews are an art. It takes years or sometimes decades to learn how to do them well. The most important thing, our prime directive, is to be kind and constructive. Soft skills The other ingredients are technical knowledge and attention to...Alexandre Gomes GaigalasA true 'hello world' LLM pipelinetag:alganet.github.io,2025:2026-01-08-23-A-true-hello-world-LLM-pipeline2026-01-08T23:00:00Z For a while now, I've been searching for the simplest, useful LLM pipeline example. Some kind of I also want something for software engineers, not data scientists. Software engineers are a different breed, and Therefore, a true 'hello world' LLM pipeline should be simple, practical, and accessible. I can't honestly...Alexandre Gomes GaigalasHow Developers Stole "Dry Runs" From Machiniststag:alganet.github.io,2025:2025-12-22-09-How-Developers-Stole-Dry-Runs-From-Machinists2025-12-22T09:00:00Z If you’ve ever run a command with a --dry-run flag, you probably knew what it did. It ran the thing, but More specifically, a dry run runs all but the irreversible parts of an operation. For example, let's say you have a command-line program called...Alexandre Gomes GaigalasPolyglot Makefilestag:alganet.github.io,2025:2025-12-17-07-Polyglot-Makefiles2025-12-17T07:00:00Z The polyglot solution for the unified Makefile looks like this: This snippet relies on subtle but well-defined differences between GNU make and nmake parsing rules. What GNU make sees: What nmake sees: This technique was used in the PHL repository...Alexandre Gomes GaigalasHello Blogtag:alganet.github.io,2025:2025-05-26-15-Hello2025-05-26T15:00:00Z For a while now, I've been wanting to start a technical blog. I decided to transform this simple, hand-crafted HTML It is as close as pure HTML as you can get. I create posts by writing the HTML by hand, and there is a 80-line (at I decided not to use any form of markdown or any form of templating for the solution. However, my solution has...Alexandre Gomes Gaigalas
