I will admit I have only scanned the article that was linked in the reddit thread, but I have a vague idea what it's about Supposedly you can use this page to find websites that use the tracking feature, though.

Could someone provide a concise technical breakdown of what "canvas fingerprinting" is and how it works? The article linked to by that Reddit page is just a lot of hand-wringing and hysteria.

There's alreadya wiki page, including links to the original paper and countermeasures.

Edit: Nope. I think that's it, though:

And it seems like much of the hand-wringing was ill-informed.

Yeah I finally got a chance to read the article. It's silly. I found the link Sitwon posted before I even came back here lol, seconding his ill-informed comment.
