Would a better word of choice be "predisposition to do arithmetic"? I've been wondering the same with artists in general (painters, musicians, etc.). Would a person without the predisposition be able to practice say Piano/Vocals for years together and reach a certain level of artistry? Any reference to academic studies on this would be appreciated.

scarecrow112··on Git partial clone lets you fetch only the large file you need
This is interesting and could be a savior for Machine Learning(ML) engineering teams. In a typical ML workflow, there are three main entities to be managed: 1. Code 2. Data 3. Models Systems like Data Version Control(DVC) [1], are useful for versioning 2 & 3. DVC improves on usability by residing inside the project's main git repo while maintaining versions of the data/models that reside on a remote. With Git partial clone, it seems like the gap could still be reduced between 1 & 2/3.

scarecrow112··on Deep Learning in the Real World: Dealing with Non-Differentiable Loss Functions
The post lists Auto Differentiation as one of the techniques that can overcome non-differentiable loss functions. Can someone explain how this is even possible? After all automatic differentiation[1] is a way to compute gradients/derivatives in a way which could become costly if otherwise done(symbolic differentiation[2]). The function or the operations defined in the function(in case of source-to-source differentiation[3]) needs to be differentiable.

Jeez this is scary! This very much sounds like the domain blocking incident [1] that Zoho faced sometime back.
