I trust you all take the opportunity to enjoy the fun curl's --libcurl option brings after that security report debacle.
1. run any #curl command line
2. add "--libcurl template.c" to the command line and run it again
3. there, a fine source code embryo to start your libcurl using app from

Electroniq WIP. Never a dull moment. After surviving a frustrating battle with libcurl, I am now diving head first into the fascinating world of Debug Adapters... My longstanding wish is to have sourcelevel debugging of 6502 code in VSCode connected to my emulator 🤯 Wish me luck

Where did the #libcurl poster girl go?

A libcurl postergirl?
If you click the image you’ll see a full-resolution screendump for my recent search for “libcurl” on google. Where did that (image of a) girl come from? Judging from where it appears on the results page right next to the information about the cURL project you can’t but assume that she’s somehow related to the project.
That’s of course not true. When moving the mouse over the image I get a tooltip with a funny “hair curling” URL and that’s also where a click on the image takes me.
A mighty weird way of presenting a search result if you ask me!

![Subject: Just a quick thank you for your existence
Hi Daniel,
I was digging around in the credits section of an app (YouTube
on my Xbox, actually), and I saw “libcurl” listed - and your
name came up when I looked into it. I had no idea one person’s
work has helped support so much of the internet I use every
day.
I just wanted to say: thank you. Not just for the code, but
for the spirit behind it. The way you’ve built and shared
libcurl, all these years, quietly powering so much without
expecting credit… it really moved me. Most people never see
that kind of work, but I stumbled across it and it left an
impression.
So this is just a small message to say:
Thank you for existing.
