["Michael A. Smith (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-2030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16961617#comment-16961617 ] 

Michael A. Smith commented on AVRO-2030:
----------------------------------------

Here is a copy of the original I found on the [Wayback Machine|https://web.archive.org/web/20140707075906/http://www.scribd.com/fb-6001967/d/84795-Crc].

The same document can be found at [a different URL on scribd|https://www.scribd.com/document/84795/Crc]. (Sigh.)

It does indeed look like this Scribd link was of a work-in-progress edition of [Hacker's Delight|https://books.google.com/books?id=XD9iAwAAQBAJ&pg=PA319&dq=hacker%27s+delight+chapter+14&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwjv1L_OuMDlAhXxc98KHXzoDI0QuwUwAHoECAIQBg#v=onepage&q=hacker's%20delight%20chapter%2014&f=false]

> The [1.8.1 specification|https://avro.apache.org/docs/current/spec.html#N1088B] has a sentence saying:
> bq. Readers interested in the mathematics behind this algorithm may want to read [this book chapter|http://www.scribd.com/fb-6001967/d/84795-Crc].
> The URL http://www.scribd.com/fb-6001967/d/84795-Crc now serves up a 404. Does anyone know what book the link was pointing to?
> Searching around leads me to think it was probably pointing to "14-2 Theory" of _Hacker's Delight_ by Henry S. Warren. If so, it would be nice to either update or remove the hyperlink and have the text cite the book and chapter by name so that interested readers can still find it even if an updated link were to go away.
