Optimal configuration
This blog will have posts dealing with programming in support of my research activities. Since 2015 (give or take a year), the vast majority of my codes are written in the Julia language using the Emacs editor. The posts will vary from actual code for whatever research project is current to tricks and tips for using Emacs to make writing code efficient, to analyse results (data analysis, visualization), and to disseminate outcomes (writing papers and conference presentations).
You can find me on Mastodon should you wish to comment on this blog.
