My main regret about not producing a webcomic* is that I don't have a reason to provide timely updates about what is going on in my life.

*I don't produce a webcomic because although it would be cool, I think other people already do a much, much better job of it.  Sort of like working for NASA.

Find PDFs that are not OCRed (Windows grep)

Works reasonably well, although some files may have font properties without the word "Font" (capitalization matters).
Open CMD prompt
dir Desktop (or whatever target directory)
grep -L Font *.pdf > list_of_files.txt
-L = only return file names that do not match
-r = Recursive

Apple Mail Rules Broken in Yosemite (OS X 10.10)

This has been bothering me since I upgraded to Yosemite earlier this summer.  I finally found an answer: turn on iCloud syncing for email.  I did not need do any if the file copying mentioned in the linked solution.

In case you're wondering: No, I am not a rules fanatic, but one IMAP email account through my hosting company has an issue with spam.  I turned on Spam Assassin, which tags the junk, and then I use a rule to put those messages in the junk folder, just in case there was a false positive.
