Local Jekyll based website generation

In an ideal scenario, your Github served website could be build locally, with the same output structure and layout.

Keras with GPU on Mac using PlaidML

Since Apple and nVidia broke up harshly a few years ago, the official support of all nVidia GPUs were stopped. Shortly after, all deep learning frameworks stopped their support of GPU acceleration on Mac. Now, there is finally a simple and productive solution: using Keras with PlaidML.

PlaidML provides backends for Keras without requiring CUDA and nVidia hardware. It event supports Metal on Mac to provide a great improvement of performance. Now we can utilize our AMD GPU on Mac to drive Keras!
