seam_carving.jl about 18s191 HOT 2 CLOSED

There could be a few things here, I'm not sure which one is the most likely culprit...

I've run Julia 1.5.3 64-bit portable on a Windows 10 machine and can confirm that the download code runs fine, as does the rest of the notebook.

What version of Julia do you have installed?

There could be an upstream issue with download.jl in Julia Base.

One possible answer is editing the bad cell to use download_powershell instead of download

curl error 35 is an SSL error

The SSL error could be a red-herring, since I was seeing cmd.exe complain about HTTPS when I was using single quotation marks around the file target (i.e. 'C:\Users\ruper\AppData\Local\Temp\jl_2fRSvgqCWA').

Can you access the file by changing the URL to "http://cdn.shortpixel.ai/spai/w_1086+q_lossy+ret_img+to_webp/http://wisetoast.com/wp-content/uploads/2015/10/The-Persistence-of-Memory-salvador-deli-painting.jpg"

Can you access the file on a different wifi e.g. at a coffee shop?

If that works then the problem has to do with the network you're using and/or the certificate store, not specifically Windows.
Unfortunately it's my understanding that SSL errors are pretty difficult to fix.

It sounds like this was a university/government firewall, or just a "flaky connection" or "internet weather".

We tried looking for a more stable website to use, like wikimedia: https://en.wikipedia.org/wiki/File:The_Persistence_of_Memory.jpg
but there are only low-resolution versions available, because the work is not yet in the public domain (1931).

The link we used is high-resolution, because it is actually not the work by Salvador Dali, it is a replica! (Posted online by the author)

I have updated the notebook to not use a redirect anymore, which might help, but there's nothing more we can do.
