is possible use both recur , post-condition functionality in same clojure function? hoping throw exception using post-condition, clojure appears trying wrap exception throwing code after recur somehow, (just stupid example) functions cannot evaluated. (defn countup [x] {:pre [(>= x 0)] :post [(>= % 0)]} (if (< x 1000000) (recur (inc x)) x)) i'm using clojure 1.3 @ moment. if @ implementation of defn @ https://github.com/clojure/clojure/blob/master/src/clj/clojure/core.clj#l3905 you'll see body of function gets modified tail calls pushed out of tail-position. 1 way around use auxiliary function call recur'd function , put post-condition on instead: (defn- countup* [x] (if (< x 1000000) (recur (inc x)) x)) (defn countup [x] {:pre [(>= x 0)] :post [(>= % 0)]} (countup* x)) (countup 999999) ;=> 1000000 (countup -1) ; assert failed: (>= x 0)

i have following class def initialize @var = 0 end def dosomething @var+=1 end end class b < def initialize super end def func puts @var end end the problem when call = a.new a.dosomething b = b.new the value @var returns 0 how change code return "new" value of var (1)? quick answer, if understand classes, inheritance , objects : replace @var (an instance variable, , therefore different in a , b ) @@var (a class variable, , therefore same in instances of class a ). otherwise, question indicates have fundamental misunderstanding of what's going on classes, objects , inheritance. your code following: defines class, called a . blueprint can create objects. declares when object of type a created, object should given it's own private copy of attribute, called var , set 0 . declares objects of type a can asked dosomething , increases value of object's var 1. defines class called b , special...

say have integer-indexed array of length 400, , want drop out few elements beginning, lots end, , middle too, without altering original array. is, instead of looping through array using indices {0...399} , want use piecewise continuous range such as {3...15} ∪ {18...243} ∪ {250...301} ∪ {305...310} what data structure describe kind of index ranges? obvious solution make "index mediator" array, containing mappings continuos zero-based indexing new coordinates above, feels quite wasteful, since elements in sequential numbers, few occasional "jumps". besides, if find that, oh, want modify range bit? whole index array have rebuilt. not nice. a few points note: the ranges never overlap. if new range added data structure, , overlaps existing ranges, whole thing should merged. is, if add above example range {300... 308} , should instead replace last 2 ranges {250...310} . it should quite cheap loop through whole range. it should relatively cheap query val...

i've got 3rd party component uses traceswitch functionality allow me output traces of what's going on inside. unfortunately, running switches in verbose mode, textwritertracelistener consumer (outputs file) slows down application much. it isn't critical traced data written immediately, there way data written on lower priority thread? perhaps task? edit upon further investigation, seems merely turning on switches without attaching listener causes slowdown. i'm going hold of component provider. would still interesting hear answer though. write own extension tracelistener. in extension, put trace strings onto list<string> , when count gets high enough, write list out file , clear list start again. flush list on dispose(). this can extended use thread pool queue new task actual write. this doesn't guarantee improve performance. if sure io slowing things down.

so here z-index issue in ie7 have ran into. found explanation of problem else without fix. when have positioned element inline z-index of 0, javascript doesn't return correct z-index. if z-index set element in stylesheet return z-index instead. same result using jquery too. make html file following: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> <script type="text/javascript"> $(function(){ $('button').click(function(){ alert($('#mainbox').css('zindex')); }); }); </script> <style type="text/css"> #mainwr { position: relative; z-index: 2; border: 1px solid #333; width: 200px; height: 200px; } #mainbox { z-index: 1; border: 1px solid #555; width: 100px; height: 100px; position: absolute; top: 50px; left: 50px; }...

i use ajax load #article content single.php page template filterable image navigation is. the content loads fine , filter navigation works. when try copy&paste link new tab deeplinking won't work. i figured out problem filterable navigation filters adding #foo url. if remove function/plugin works. the ajax adds event listner internal links except few defined hereby: $(document).delegate("a[href^='"+siteurl+"']:not([href*=/wp-admin/]):not([href*=/wp-login.php]):not([href$=/feed/])", "click", function() { location.hash = this.pathname; return false; }); i tried adding internal links filter in there, had no success :not[(href^=#)] , similiar because don't know logic. i need exclude links #portfolio-filter li a you add class of links don't want include, like: $('#portfolio-filter li a').addclass('ignore'); and work $('a[class!="ignore"]') selector.

i'm trying mix 6 sound clips together. imagine each clip single guitar string pluck sound , want mix them produce guitar chord. here, clip array of real numbers in range [-1,1], each number mono sample. double mixed_sample = mix(double sample1, ..., double sample6); please, implement mix ! you have got kidding. mixing simple addition of signals. double mix(double s1, double s2, double s3, double s4, double s5, double s6) { return (s1 + s2 + s3 + s4 + s5 + s6); } next step provide individual channel gains. double variable_mix(double s1, double s2, double s3, double s4, double s5, double s6, double g1, double g2, double g3, double g4, double g5, double g6) { return (s1*g1 + s2*g2 + s3*g3 + s4*g4 + s5*g5 + s6*g6); } of course, kind of pain in ass code, , parameter-passing overhead eat alive, have do.

i know can this: std::vector<double> vec; std::back_insert_iterator<std::vector<double> > it( back_inserter(vec) ); = 4.5; but i'd similar (in syntax ) std::set (and use front_insert_iterator instead of reference set , use set::insert ). possible, or forced use reference o set? maybe should use std::merge and/or std::set_intersect (this allow error reporting in case of duplicates)? approach? thanks! you don't push_back or push_front set , because (conceptually) set sorted associative container. can this, though: #include <cstdlib> #include <set> #include <iterator> using namespace std; int main() { typedef set<int> myset; myset si; insert_iterator<myset> it(si, si.begin()); *it = 1; *it = 2; } edit: note begin() iterator initialized not elements put. rather, hint stl start looking put item. edit2: as per comments below, wanted way check "disposition" of inser...
