You do not have permission to open the application Canon IJScanner2

YOU DO NOT HAVE THE PERMISSIONS!

Ugh. Upgrading to Big Sur 11.5.1 murdered my old flatbed scanner, which I use all the time. Evidently, it's a problem for many many many people. The following sequence worked, but I can't guarantee that it will work for you as well, since I deleted, added, re-deleted, upgraded and downgraded all kinds of files until it finally showed up without an error:


  1. Delete the scanner from Preferences
  2. Delete Canon utilities
  3. Remove any Canon-related files from /Library/Printers/Canon
  4. Remove any Canon-related files from /Library/Image Capture/Devices
  5. Reboot
  6. Install the misd-mac-ijscanner2-4_1_4-ea21_3 driver
Don't install the LiDE 210 Scanner Driver Ver.18.2.0 (Mac) file, that seems to be both useless and part of the overall problem. Just use Image Capture and you should be fine.

Mark paid Substack posts as read in FreshRSS automatically

Substack supplies an RSS feed for each site, but there is no information included within that would help discern whether a post is paid or public. Filters based on searches such as "Read more" create too many false positives and are unreliable. After playing with this for quite a while, I realized that if you scrape the site yourself you can create a flag for paid articles and have FreshRSS mark anything with the flag as read. It only works with FreshRSS version 1.25.0-dev or above, since there was previously an issue with flags being ignored during scrape operations. I've included example code for Many Such Cases, written by Magdalene J. Taylor. I highly recommend that you subscribe and follow her writing, as she is tremendous! All you should need to change is the title and URL. As a bonus, this scraper also supplies a larger thumbnail image than the official feed. Substack RSS feed (with filter for paid articles)
