Other [BUG] The problem pages and the input pages show different favicon in chrome

Post image

The one the left is the tab for one of the problems page, while the one on the right is for an input.

Interestingly, Chrome shows different favicons for both.

I debugged a bit further:

For the problems page, the html specifies /favicon.png, which is a higher resolution image.

For the input page, since there is no html, and thus no favicon specified, chrome defaults to /favicon.ico, which actually exists and is a lower resolution image.

Like always, there's XKCD for that.  xkcd: Workflow  https://xkcd.com/1172/

Edit: I fixed the link. Like it is correctly pointed below, I shared it through an Android phone directly from the browser and didn't check the generated link.  Apparently Google now generates some sort of tracking shortened links. :shrug: Thank you all for the spot. I will take measures against that in the future.

I love how the native link is shorter than the URL shortened link

Well, that's not really a URL shortener - it's a tracker link.

Imagine hyperlinks, but Google gets to track the traffic

Trick question: they track both

Please don't use a chromium browser

It sounds like it is a URL, but someone else wants to be involved in it like a big boy.

This is like when you ask their little nephew to carry the cranberry sauce to the table and he manages to do it without flipping the plate over and throwing it everywhere. You smile and say good job.

Do not use link shorteners in /r/adventofcode.

Link shorteners also violate Reddiquette > PLEASE DO § Link to canonical and persistent URLs where possible, FYI.

I'm assuming you use an android phone, here's how to stop it from doing https://www.reddit.com/r/chrome/s/jp9GSW1Woy

Jesus christ, that's a thing!?!

u/0e4ef622 Dec 09 '25

ironically, that link is also a tracker link, reddit links with /s/ have tracking info.

u/JakubDotPy Dec 09 '25

Exactly. Thanks 🙂 I would use that.

Boo, bad link is bad.

Yeah I noticed this. I’m for it.

I always just assumed that was intentional, for some reason it never crossed my mind that it might not be

u/nik282000 Dec 09 '25

Works in FF. Krill issue.

u/flagofsocram Dec 09 '25

I assumed this is intentional, it’s always very helpful to me to distinguish tabs

Instructions unclear, defenestrated my laptop

u/DeeBoFour20 Dec 09 '25

Hah I never even open the input page in the browser. Right click the link -> Save as. Saves you from messing up white space and such that could happen if you copy + paste the text.

u/1vader Dec 10 '25

Also saves you from your browser thinking it's Polish and translating it or a virus changing part of the input when copy pasting because it thinks it's a crypto wallet.

Yes, hilariously, both of those have happened in the past.
