I am curious about the word "Caldoniafied" meaning, roughly, hard headed, and presumably coming from the song entitled "Caldonia"  ("Caldonia, Caldonia, what makes your big head so hard?". )Louis Jordan had a big hit with it, and BB King still sings it. This word was used by my Brooklyn landlady in the 1980s. Was it in general use at this time?  Also, was it a huge insult? I am writing a novel set at this time and wanted to use it as a light term. Google doesn't have much about it.


Question: How can I tell if a downloaded ISO is complete?
Answer: If the source did not provide any checksums for you, you should first check the file size and see if it matches. If not, it means that your download is ended prematurely. 

Also in linux, you can use wget, with -c command to continue aborted downloads. I have never tried to continue a download started from another application (mostly browser) but I think it should be fine.

I always use wget as a download manager as it fails rarely and allows continuing aborted downloads. One should have a download manager in their tools for downloading large files consistently even though one does not use it every day.
