ASP.NET Core offers a simplified hosting model, called minimal APIs, that allows us to build lightweight APIs with minimal dependencies. Although minimal APIs don’t use controllers, and require only minimal code and minimal configuration, they nevertheless allow us to implement advanced features and important security mechanisms such as Cross-Origin Resource Sharing, or CORS. In this post, we’ll examine how we can work with CORS in minimal APIs in ASP.NET Core. To use the code examples pr...| Google’s Jules coding agent adds CLI, API | InfoWorld
En este experimento parto de una base .NET con deuda técnica deliberada y la someto a un análisis exhaustivo con NDepend. A partir del informe (reglas, métricas y CQLinq), priorizo los smells con ayuda de una IA generativa y aplico refactors en tres oleadas (Quick Wins → Media → Estructural). El resultado es una reducción medible de complejidad, duplicación y acoplamiento en horas, no semanas, y un pipeline con quality gates que evita regresiones. NDepend me da la radiografía; la IA...| JMFLORESZAZO
En los últimos meses (o último año), todo el mundo habla de la Inteligencia Artificial (IA). Hay titulares que insisten en que la IA nos va a quitar el trabajo, que no está lo suficientemente madura o que las empresas no ven retorno de inversión (ROI). Pero, ¿sabes qué? Me parece que cuando hablamos así, detrás de esos grandes titulares, olvidamos lo que realmente importa: el para qué de la IA. Porque es justamente en los casos concretos, reales, donde la IA puede brillar.| JMFLORESZAZO
This post will cover the use of PID controllers in video games. If you’ve ever used your car’s cruise control, flown a quadrocopter, or piloted a rocket, then there’s a good chance that you’ve used a PID controller. A PID controller is a type of control loop that’s used for automation. PID controllers are flexible ... Read more| VAZGRIZ
Now that we have the flight mechanics and HUD, we can start working on the weapons and AI. The AI will have all of the same capabilities and limitations as the player.

I’ve been playing Ace Combat and Project Wingman recently. This inspired me to write my own flight simulator using Unity3D. I wanted to make a flight sim with more depth than the arcade flight sims, while still being accessible. You can think of realism as a spectrum. On one end is Ace Combat and at ... Read more| VAZGRIZ
In this post, I will describe a shader for Unity3D that recreates the look of a reflex sight. A reflex sight projects the image of it’s crosshair to some distance in front of the viewer.

I’ve been playing some roguelikes recently, so I wanted to try writing my own procedural dungeon generator.

tl;dr Since .NET Core 3, the dotnet runtime has provided a low-level hook that allows injecting managed code that will run before an application’s entry point. This hook makes it possible to effectively backdoor any .NET application on a host (Windows, Linux, and macOS). You may ask| Rasta Mouse

In Unity, coroutines are essentially methods that execute across several frames. They are, in a sense, some syntactic sugar that lets you avoid having to keep track of the state of a sequence of operations (for instance, fading from one color to another) in member variables of a behavior. Instead, all state can be method-local. Refer […]| IceFall Games

LINQ (which stands for Language Integrated Query) is a library of collection manipulation methods that makes organizing and picking data out of collections much easier. LINQ can save a lot of time that would otherwise be spent writing complicated for or foreach loops.

Though we don't really see as many of them as we used to, they are still with us. One helps indicate if a 10-key is in number or cursor mode. Another helps show when we use capital letters without holding the shift key. You might even have another to show if you accidentally hit the scroll lock key.
