.NET SDK global.json

In the context of the .NET SDK, global.json is a file that allows you to specify which .NET SDK version to use when running .NET CLI commands, ensuring consistent builds across different development environments. 

  • The .NET CLI searches for a global.json file in the current working directory (which isn’t necessarily the same as the project directory) or one of its parent directories. 
  • The global.json file allows you to specify the desired SDK version, ensuring that all developers and CI/CD pipelines use the same SDK version, which helps avoid build inconsistencies. 
  • A basic global.json file might look like this: 
{
  "sdk": {
    "version": "8.0.404"
  }
}

Google Map Tiles

Google offers 2D, 3D (Photorealistic), and Street View tiles via the Map Tiles API, enabling developers to build immersive and customized map visualizations, including access to roadmap, terrain, satellite imagery, and street-level views

2D Tiles:

  • Image files that divide the world into an indexed grid, offering roadmap, terrain, and satellite imagery.
  • Ideal for basic map visualizations, navigation interfaces, and geographic data display.

Photorealistic 3D Tiles:

  • 3D meshes textured with high-resolution imagery (OGC 3D Tiles format), providing realistic views of buildings, monuments, and landmarks.
  • Useful for stunning 3D perspectives, enhanced navigation, and storytelling.

Street View Tiles:

  • Panoramic street-level images that allow users to explore landmarks, natural wonders, and interiors of places like museums or restaurants.
  • Used for immersive experiences, virtual tours, and detailed location views.

Vibe Coding

Andrej Karpathy

There’s a new kind of coding I call “vibe coding”, where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. It’s possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good.

Semantic Diffusion

…while complaining about how the definition of “vibe coding” is already being distorted to mean “any time an LLM writes code” as opposed to the intended meaning of “code I wrote with an LLM without even reviewing what it wrote”.

Personally I use “vibe coding” when I feel like this dog.
