You can try CAP (Categories, Algorithms, Programming) in your browser running Jupyter notebooks interactively in Binder.
To start a CAP session with a worksheet on abelian categories, perform the following steps:
Click on or open https://mybinder.org/v2/gh/sebastianpos/cap-aachen2018/master in the browser.
Loading repository: sebastianpos/cap-aachen2018/masterwill be displayed, followed by a non-interactive preview. Please be patient, since it may take a while, depending on the current load on Binder. When the server will be ready, you will see the main Jupyter screen with a file browser.
Click on the
AbelianCategories.ipynbfile to start a Jupyter notebook on abelian categories.
