Today 8:08 PM John Lumley What a gorgeously simple example! Debbie Lapeyre Ain't it the truth! C M Sperberg-McQueen One account of the story of recursion in Algol: https://vanemden.wordpress.com/2014/06/18/how-recursion-got-into-programming-a-comedy-of-errors-3/ Evan Lenz According to Amazon, A Discipline of Programming is in its 59,638rd edition. Impressive! Debbie Lapeyre And not just for algorithms. When I was a little girl, the relational database was a lovely thought experiment that would never be implemented for lack of computing power and space 59,638 wow. There are no words. Evan Lenz Yes, there aren't any left Geert Bormans My copy has the date 1976 in it, no mentioning of "edition" so it must be the first Evan Lenz Amazon must not be using XML C M Sperberg-McQueen 59,000 editions in 45 years, something more than three a day? I never knew EJD was that popular :-) Geert Bormans starting from 1976 that means roughly 3,5 editions per day... mine looks already POD from Amazon. Not sure I will get $461 for it... worth the read however Bob Stuart Probably JASON that way they don't have to validate :) C M Sperberg-McQueen well, to be fair, it's hard to specify plausibility in a schema Bob Stuart Probably would not have thought of it but some schematron claiming more than N editions/X time is at best a warning could be safer Owen Ambur Glad to see listing of XForms implementations at https://www.w3.org/community/xformsusers/wiki/XForms_Implementations Debbie Lapeyre Agreed Bob Thank you, Steven, many good things start at Balisage Evan Lenz 👏 Norm Tovey-Walsh I missed some of that, Steven, because I had to go get the pizza, but the parts I heard were very nice. Well done. Steven Pemberton https://www.xml.com/articles/2019/02/08/viewing-data-xforms/ https://homepages.cwi.nl/~steven/xforms/xforms-hands-on/
