Why Garbage Collectors Should Avoid the Use of Reference Counts

I made a comment in one my posts some time ago that I thought SPITBOL was superior to Python in that it contains a compacting mark-sweep garbage collector with recognition of sediments.

Python uses reference counts to detect unreachable memory. SPITBOL was written in the 1960’s, so the use of compacting garbage collectors was a well known technology when Python was created in the 1980’s.

For example, I one wrote a small Python program that ran in quadratic time due to the use of reference counts.

A user commented that they thought this was a snide remark, and that the use of reference counts was perfectly fine.

I just downloaded Remarkable, a markdown editor and viewer, written in Python.

I just used it to process a markdown format file, and got the following error message:

As a young child one of my favorite comic strips was Snuffy Smith.

 

Snuffy often ended a conversation by saying, “‘Nuff Said.'”

Well, this is for the snide commenter:

‘NUFF SAID.
