MNIST database Updated +Created
60,000 28x28 grayscale images of hand-written digits 0-9, i.e. 10 categories.
Playing with it is the de-facto computer vision hello world.
But it is important to note that as of the 2010's, the benchmark had become too easy for many application.
The dataset can be downloaded from yann.lecun.com/exdb/mnist/:
wget \
 http://yann.lecun.com/exdb/mnist/train-images-idx3-ubyte.gz \
 http://yann.lecun.com/exdb/mnist/train-labels-idx1-ubyte.gz \
 http://yann.lecun.com/exdb/mnist/t10k-images-idx3-ubyte.gz \
 http://yann.lecun.com/exdb/mnist/t10k-labels-idx1-ubyte.gz
but doing so is kind of pointless as both files use some crazy single-file custom binary format to store all images and labels. OMG!

Waring-Goldbach problem Updated +Created
It is exactly what you'd expect from the name, Waring was watching Netflix with Goldbach, when they suddenly came up with this.
Species bootstrapping from DNA Updated +Created
Synthesizing the DNA itself is not the only problem however.
You then have to get that DNA into a working living form state so that normal cell processes can continue:
  • for viri see: synthetic virus
  • for bacteria, you have to inject it into a cell
  • for placental animals, you also have to somehow simulate a compatible placenta. It is likely easier for eggs.
