everything wrong with free software

 "obedience breeds foolishness"

### look-in-the-mirror by Thomas Grzybowski *originally posted:* sep 2021 Just the other day I was reading about the "Qi" computer language - the fore-runner for Shen - and thought I would give it a try. It's worthwhile doing this, as Qi running compiled under SBCL is one of the fastest Horn clause logic and unification implementations available anywhere, Shen being a little slower (though Qi does lack some small amount of the functionality of Shen). Another big plus is that it is licensed under GPL2, whereas Shen is not. So, I do a DuckDuckGo search on "Qi language", and it pulls-up a reference to: => https://www.cliki.net/qi - which directed me to: => http:// www.lambdassociates.org/ with the result: "Hmm. We’re having trouble finding that site." OK, not to be discouraged, I kept at it, using search at Sourceforge . I found it ! Last Update: 2014-03-08! (Oh-Boy!): => https://sourceforge.net/projects/qilang/ And here is what I found: "Activity for qilang - No activity to display." It seems that Qi _was_ here, but is not any longer, for some reason... So, never to give up while still awake, I did a further search using Google (which (for reasons beyond the scope here) I try to avoid). Searching "Qilang Lisp" I found this web site: => https://www.findbestopensource.com/product/qilang - Which then directed me here: => https://code.google.com/archive/p/qilang/downloads And There, Success! The original code compiled directly from the zip files using CLISP worked without modification, but I had some problems under SBCL. To get it to work there I had to make some modifications to a couple of the supporting lisp files. But now I am thinking: the source code for Qi is no longer at Lambda Associates, and was somehow lost or dropped or deleted from the Sourceforge repository, and it was only by chance I found it at Google's code store (which is also no longer active). And now I had done some work to make useful modifcations... So, I realize: mirroring is Really Really important! Therefore, I have created a mirror repository for the Qi code: => https://notabug.org/tomgrz/Qi_language_9.2_texts - and also: => https://notabug.org/tomgrz/Qi_language_7.2_texts Happy Hacking!
