# Experience Report: Steps to "Emacs Hyper Notebooks" Joseph Corneli, Raymond Puzio, and Cameron Ray Smith We present a short experience report from the perspective of two long-time Emacs users and one relative newcomer. Our motivations relate, broadly, to reproducibility of research in science. We reflect on our experiences with off-the-self solutions available through the Emacs package manager, and describe some of our custom extensions. When working on a scientific research project, one typically has multiple different computer programs running at the same time. For example, we may use a computer algebra system such as Maxima for calculations, an interactive language such as Julia for numerical computations, TeX for writing up results, a reference manger such as Zotero for the bibliography, Roam for note-taking, and Jekyll for blogging. Switching and moving content among these programs can be distracting, time-consuming, and prone to error. These issues are compounded when there are several collaborators involved. We explore a solution that looks toward building better "computational notebooks" using Emacs. We take Org mode as our foundation. As many in this audience will know, Org mode integrates features such as writing, task management, program evaluation, typesetting, presentation, and navigation. Tightly integrated add-on packages round out the picture either by directly replacing the functionality of the other programs mentioned above or automatically dispatching commands to them. We outline both the pleasure and pain involved in this experience.
