The only question is when, and how much of it you get back. Eight months into a project you need to regenerate Figure 3 with one more data point. There are four scripts with promising names, two of them called something like analysis_final, and neither produces the numbers in your draft.

Nothing was deleted. Nothing was corrupted. You simply have no record of what you did, and that turns out to be the same thing as not having done it.
This is the practical subset of reproducible research, written for a student with a project and a deadline. Not Docker images and continuous integration. Six habits, none taking more than an afternoon, that between them close every way a project falls apart.
Why raw data is read-only, and how to enforce it at the filesystem level
Git in seven commands, without the branching mythology
One command that rebuilds every figure and number from raw data
The environment file everybody skips, and why silent version changes hurt most
Assertions and seeds: the tiny subset of testing that pays for itself
A project template, a Git card, and a checklist built to be photocopied

Download this editionEverything here is quick to set up, light on your pages and built to do one real job well. I only charge for the tools that can make you money. The rest are free.
I design, build and support every product on this site myself. When you email me, the person reading it is the one who wrote the code.
I’d rather ship one tool you’d miss if it vanished than ten that sit in your plugin list doing nothing.
18+years building websites, plugins and stores, since 2008
Switch a feature off and it loads nothing. What does load stays small. A tool that replaces a plugin shouldn’t make your pages slower.
Clear screens, sensible defaults and settings written in plain English. If you need a tutorial for the basics, that’s my design mistake, not yours.
Full keyboard support, visible focus, proper labels and text you can actually read. When more people can use your store, more people can buy from it.
My paid tools help you sell, renew, license or convert. If one just sits in your stack, I haven’t done my job.
I won’t charge for anything that can’t make you money. The free tools get the same care as the paid ones, down to the last setting.
Both editions are free and contain the same complete book. Pick the layout that matches how you read.
