A file renaming tool for humans

Sun, 01 Feb 2026 00:00:00 +0000

I deal with a lot of PDFs. Medical invoices, insurance correspondence, bank statements, tax documents—they all arrive with names like e134-a1cf-4b4b-af65-ccf83c5270cb.pdf or Document(3).pdf or, my personal favourite, scan.pdf. Every. Single. Time.

So I started renaming files to something like 2025-09-30-125.00-rahona-clinic.pdf. Now I know what it is without opening the thing - an invoice, with the date and amount right there in the name. I'm halfway to the spreadsheet already. And thanks to ISO date format, they sort nicely too.

Firefox: disable autofill in forms

How to disable autofill (or autocompletion) in Firefox forms

For some reason they don't make this so straightforward any more.

Just go to about:config and set

browser.formfill.enable = false
browser.formfill.expire_days = 1
services.sync.prefs.sync.browser.formfill.enable = false

There's a suggestion that setting browser.formfill.expre_days to 0 is more secure for expiring existing saved data, however 0 often means never expire. Without looking at the code, I'm just going to err on the (to my mind) safer bet of setting it at 1.

This is a reference companion to my series on understanding AI. Before diving into the practical guides and opinion pieces, take a moment to understand the risks.

Using AI-generated material

Before using information or data generated by an AI service, be aware:

Generative AI can hallucinate, which is another way of saying it makes things up. Check all information before using it. Carefully parse summaries in case it misses nuance or key information.
