When and Why Your Team Should Create an SDK

Posted on 21 Apr 2025 - 14:10
Goals of an SDK The main goal of an SDK is to simplify someone’s life. That can be you, your team or your customers. An SDK exists so developers can focus on building their product, not dealing with low-level technical details. The SDK’s creator takes on the work of developing, evolving, and maintaining it so others don’t have to. For example, without an SDK, integrating any REST API service means handling API keys, building all the HTTP communication, managing caching, wrapping REST calls into reusable methods and more. For many developers, this is a distraction from their actual goal. It adds risk, uncertainty, and technical debt.

Git: using different SSH keys in your repos

Git: using different SSH keys in your repos When working with different projects and especially if you are a contractor that interacts with multiple clients, a common situation is that you have to access gitlab, bitbucket, github or other git cloud service with different credentials, usually to maintain access to other repositories while using an ssh-key that’s specific for a client. Generating the key pair If you haven’t generated a key yet, use the ssh-keygen command in git-bash. This generates public and private keys, by default in c:/Users/your_username/.ssh/. Make sure you specify a name for your new key that doesn’t overwrite any of the ones that are present in the .ssh folder. In this example our key is called id_rsa_second. If you don’t know how to add the generated public to your bitbucket account, see how to Set up personal SSH keys on Windows in Bitbucket Cloud.

Calculating Triangle Normals

Unity’s Mesh class nicely exposes the mesh’s topology and allows us to manipulate it with ease. The access to vertex positions, triangles and normals is immediate thanks to the availability of properties like Mesh.vertices, Mesh.triangles and Mesh.normals. Nonetheless, all developers who do any wizardry on meshes unavoidably come across a blind spot: triangle normals. Many think that Mesh.normals will give enough intormation to know what way the triangle is facing but they soon discover that the vectors that come with Mesh.

Compute width and height from diagonal and aspect ratio

Posted on 8 Nov 2021 - 11:42
Problem When the information about a screen, a window or a generic rectangle is limited to its diagonal and an the aspect ratio (the width divided by the height) and we need to know width and height, we have a little problem. It must be easy right? Well.. not as obvious as most people expect (how many of your friends know the right answer?) but still the solution isn’t difficult and it’s a nice example of use of some known quadratic formulas.
