### NY Lost Funds

 Dena|Lap How can I create a list thats empty, but still makes me able to use (nconc ...) on it ?I currently have a (list), naturally (nconc ...) doesnt work on that form nyef You can't. Dena|Lap oh nyef Well, okay, maybe you can, but if so, you're using nconc wrong. Dena|Lap currently I work around it by just adding a item as nr1 in the listoh nyef (Are you trying to use nconc for its side effect?) Dena|Lap Is it wrong of me to use nconc to add single items to the list ?nousing it to add items to a list gigamonkey Dena|Lap: probably. rpg Dena|Lap: Why not just push things onto it?Dena|Lap: Do you want to add to the end? You could just do a bunch of pushes and nreverse... gigamonkey Where wrong = potentially horribly ineffecient Dena|Lap ahhrpg, yes exactly =)great, thank you all :) Zhivago you could just make a queue ... Dena|Lap but the easiest thing I could do must be to push all the items, then reverse ?most efficient also no? luis Hmm, billc asked for podcast suggestions the other day. I can't find it in the logs, did he get nice suggestions? Zhivago dena: what problem are you trying to solve? Dena|Lap zhivago, I'm calculating primes, and adding each number to a list, so I can later display/modify themso I loop through adding each new prime into the list Zhivago so the order of the primes isn't actually important? rpg Dena|Lap: You could use (LOOP for new-prime = collecting new-prime) Dena|Lap zhivago, no, actually the order is importantrpg, hm thats another possibility Zhivago why? Dena|Lap I want them in the order they are calculated tmh HelloWhen defining a structure, is it possible to refer to other fields in the initform of a field? luis foom: heh, so ats and I seem to be fighting for "sbcl-linux-x86_64" how does that work?foom: redundancy?hmm, the page does seem to suggest one builder can have multiple build slaves action rudi has been browsing http://vistasmalltalk.wordpress.com/ instead of working rudi has been browsing http://vistasmalltalk.wordpress.com/ instead of workinghe implements a Lisp on top of Flash and WPF/eand provides a smalltalk syntax via reader macroswith graphics, class browser etc
