For day 3 of project recaps from this year's unconf, here is an overview of the next five projects. Stay tuned for the last recap tomorrow. In the spirit of exploration and experimentation at rOpenSci unconferences, these projects are not necessarily finished products or in scope for rOpenSci packages. Let's dive into today's 5 projects in focus! Summary: jobstatus helps keep an eye on how complex and long-running jobs, including jobs running in parallel, are progressing.
