Unexpected favicon.png (but not .ico)

[adeak]

A few days ago I noticed that duckduckgo shows an unusual favicon for numpy.org:

Looking at the HTML source, I can see a favicon.png and a favicon.ico (probably related to #493).

The .ico (from https://numpy.org/images/favicon.ico) looks fine:

But the .png (from https://numpy.org/images/favicon.png) looks surprising:

Is this expected?

Taking a closer look at #493 it seems that the favicon.png shouldn't even be there, so it must be something there by accident/left over. But its existence shadows the favicon.ico we have now.

The Hugo theme page has the same favicon.png linked in its source:

    <title>Scientific Python Hugo Theme documentation</title>

<link rel="icon" href="./images/favicon.ico" />

That's from the parent theme. It gets overridden for most browsers, but looks like not for DDG. I will implement a fix. Thanks for the report!

Maybe related? This is the logo I see on the Chrome app on my phone:

[adeak]

That looks like the logo of Scientific Python. Perhaps it comes from the Hugo theme? I.e. https://github.com/scientific-python/scientific-python-hugo-theme/blob/39a60b67b3705121cbf09cbe04089218dc0cc433/static/images/favicon.ico

The following two files seem to be non-numpy favicon.ico files that are getting inherited and not overwritten in case of android phone as reported above:

./themes/scientific-python-hugo-theme/static/images/favicon.ico
./themes/scientific-python-hugo-theme/themes/hugo-fresh/static/images/favicon.png

On iPhone, I see correct favicon when I browse https://numpy.org/docs link with latest site as of 01/18/22

Most browsers favor the last favicon specified, but this does not seem to work everywhere. I will update the theme to only display "our" favicons.

The https://numpy.org/doc/ site is not generated by the scientific-python-hugo-them, so I am not sure why the scientific-python favicon appears. When I go to that page, I see the old scipy favicon. It looks like https://numpy.org/doc/ is generated from https://github.com/numpy/doc.

I've removed the hugo fresh icon, so it no longer appears here: https://numpy.org/images/favicon.png

I don't know how long DDG will cache the favicon. But they should eventually update now.

[Mukulikaa]

It looks like https://numpy.org/doc/ is generated from https://github.com/numpy/doc.

Does that repo accept PRs? I'd be happy to update favicon.ico and numpy_logo.png, which should fix the logos on that page.

[stefanv]

Thanks, Mukulikaa. You can see they currently use the SciPy logo: https://numpy.org/doc/_static/favicon.ico

PR should be made here: https://github.com/numpy/doc/blob/main/index.html#L30

DDG seems to be finding the correct favicon now:

[adeak]

Curious, I'm still seeing the old logo. Firefox 97.0b8 on debian.

I checked and it's the same with the light theme. I'll just blame caching for now and post a comment if it's still wrong in a week.

[jarrodmillman]

Yes, we probably have different caches. Please do post in a week or so when you check again. Thanks!

[Mukulikaa]

When I go to that page, I see the old scipy favicon.

I have opened numpy/doc#9 to fix this.

[adeak]

Cache finally gave in:

Thanks for the fix :)
