I have a list of references to add, plus another one or two Python algorithms. --[[User:Paddy3118|Paddy3118]] 18:40, 2 December 2009 (UTC)

Just for the record, I would like to reclaim authorship of that snippet of pseudocode from the DDJ discussion back then, quoted in the Python section that apparently started this whole page. :) No consequences other than to state it here for the record - that link is broken now, gone dead after DDJ moved their blog system to some "new implementation with new and exciting features" which included losing all the old contents apparently.
::: update: https://www.drdobbs.com/architecture-and-design/hamming-problem/228700538 not dead anymore. (web.archive.org has a copy, as well). [[User:WillNess|WillNess]] ([[User talk:WillNess|talk]]) 20:14, 13 May 2020 (UTC)
Two interesting related observations. One, very minor, I can now explain the spaces in <code>x2=2*h[ i ];</code> in the quoted pseudo-code: the old blog system at DDJ would interpret [i] ... [/i] as markers for ''italics''. Another - for me, somewhat major - is that while I came out with that pseudo-code trying to translate the classic ''Haskell'' merging-the-mappings code back into something C-like in my mind, as it turns out, it is in ''almost exact verbatim correspondence'' with the original Edsger Dijkstra's code in his book (IIRC), which I stumbled upon much later, by chance. (I had a link to it somewhere, will add later.) Amazing how it came back in an almost exact loop, this idea, back to where it started - "to Haskell and back!". Interesting... :) [[User:WillNess|WillNess]] 21:06, 20 August 2012 (UTC)▼

::Thank ''you'' for getting inspired and making this page happen! :) The book in question is Edsger Dijkstra, "A Discipline of Programming", Prentice-Hall, [http://web.cecs.pdx.edu/~cs410aph/Lectures/Smalltalk%20II/Dijkstra%20on%20Hamming's%20Problem.pdf chap. 17 "An Exercise Attributed to R.W.Hamming"], [http://i.imgur.com/tPygG.gif pg. 132]. -- [[User:WillNess|WillNess]] 17:40, 29 August 2012 (UTC)

: I forgot to say that this happens using Microsoft Windows Internet Explorer, or my main squeeze, Firefox Aurora. This is under Windows/XP with a fibre-optic internet connection. Also, I found out that it helps to shut almost everything else down that can be shut down (just applications, not services). Crossing your fingers and toes doesn't help. Time of day doesn't seem to matter. Root canal is more enjoyable. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 22:09, 18 March 2014 (UTC)
:: I mostly ignore the audio, and just request another image until I find one with low enough ambiguity I am comfortable trying it. I have not tried root canal. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 00:03, 19 March 2014 (UTC)
