here code function - great jquery cycle plugin function calculatetimeout(currelement, nextelement, opts, isforward) { var index = opts.currslide; return index % 2 ? 2000 : false; } i , working fine the last line curious about. "return" kills function , returns ever output has index variable set in above line (is integer) "% 2" divides index var 2 then "? 2000 : false" short hand if else , if statement true / false return either 2000 or false. so 3 return true , 3.5 return false example. so question why in context integer return true non-integer return false? might have thought number return true , 0 return false? guessing due type casting set? thanks

i have (assumed formed) regex expresion r. want test if regex expression single match (all letters, numbers, , escaped expressions) or swapped else. function, "haswildcards", work this: bool = haswildcards("asdf");//returns false bool b = haswildcards("asdf*");//returns true bool c = haswildcards("asdf[123]");//returns true bool d = haswildcards("asdf\\[123\\]");//returns false i using boost::regex, if helps @ all. thinking of checking if regex expression matches this: (^(([\[\^\$\.\|\?\*\+\(\{\}])))?(\\[qedwsdwsbazzb])?([^\\][\[\^\$\.\|\?\*\+\(\)\{\}])? i've tested on few expressions (using regextest tool of grepwin) so non-escaped regex symbol start, non-escaped flag,non-escaped regex sumbol in body. there alternative? did screw up? there better way? well, there's quick two-step way test this. instead of testing escaped characters and wildcards in 1 regex, first line of function remove escaped characte

'%--%' causing problem. my question : wish show articles of different categories on different pages dynamically. can ??? if using mysql, can use find_in_set function see if category wish find exists try: select * article_table find_in_set('searchforid', category_id) > 0 order id desc; where 'searchforid' repl

i have working web application uses deadbolt module. every thing working fine except unable add restrict tag view script. have tried.. @@restrict( @@group( "user" ) ) { <p> howdy </p> } #{deadbolt.restrict roles:[['user']]} <p> howdy </p> #{/deadbolt.restrict} both of above displayed on page, text, without interpolation. however following works correctly.... @subjectnotpresent() { howdy } tia, chet it seems trying use deadbolt 1 (which play 1.x) in play 2.x application. instead of deadbolt-1 should use deadbolt-2 . then this: @import be.objectify.deadbolt.java.views.html._ ... @pattern("permission-name") { ... }

i have never tried program on top of udp know fast and unreliable. question if program reliability on top of udp resulting performance make same using tcp ? i.e. worth try? key point : haven't programmed in udp , try implement reliability first time. there number of commercial solutions provide fast , reliable udp. these cost many $100ks typical installation , can expect spend same on hardware make stable. writing reliable udp harder sounds because sensitive dropped packets. i.e. works fine long lose few packets. for simple installation tcp faster, , simpler trying implement own reliable udp. suggest use udp if don't need reliability.

i installed shrewsoft vpnmanger on linux (crunchbang kernel 3.2.0-4 amd64) problem is, somehow can started sudo. can explain how can fix this? sudo /usr/local/sbin/iked& how can change iked installation available each user? thanks it's paths normal user's shell search commands. makes sense commands located in sbin dir not accessible typing command's name. commands need access protected resources accessible root . but if have luck can gain full rights means of sudo can create alias via alias iked="sudo /usr/local/sbin/iked" and add shell's resource file. to make full command accessible users typing iked can create little bash script named iked content #!/bin/bash sudo /usr/local/sbin/iked and place in /usr/local/bin . of course implies appropriate /etc/sudoers file , execute permission of iked set.

hi want perform mathematical subtraction in jquery. var whm = $(window).height()/2; var login_height = $("#login").outerheight(); var login_marign = (whm-login_height); but login_margin not work. how subtract value of these 2 variables? what trying do? if trying find margin around login (i assume case looking @ variable name) can use .outermargin() function. $('#login').outerheight(true); finds height of #login div including content, padding, border, , margin $('#login').outerheight(); finds height of #login div including content, padding, border, not margin so find margin around element do var $login = $('#login'); $login.outerheight(true) - $login.outerheight(); this return height of top , bottom margin, , if equal divide 2 find it's value. check out on http://jsfiddle.net/prt2j/1/

consider have abstract base class inheriting other class x. class override method foo1 . there few other classes a1,a2,a3 concrete classes. all concrete classes inherit method foo1 . method foo1 general algorithm should suitable concrete classes. "almost" because of 1 exception in algorithm there if condition, of classes lets a1,a3 need luanch other method foo2 in start of foo . for a2 don't need launch foo2 . the problem if if implement foo2 in class it's children inherit function well, not design? i thought of excluding foo2 interface implemented concrete classes-> not foo1 calls foo2 on base class! any ideas how solve problem in proper way? thank you the solution use in situation make layer of abstract classes classes need special foo2 derive instead. abstract class : x { public virtual void foo() { //foo logic } } abstract class b : { protected virtual void foo2() { //foo2

my postgres dump ( pg_dump > file.sql ) contains data want remove. there simple regex (or sed/awk command) delete lines between particular copy table_name statement , termination word ("."). know regex's aren't ideal not matches , multi-line patterns, tried these anyway (in sublime find/replace): "copy ((?!\\[.])*.*)*" "copy ((?!\\[.]$)*(.[\n])*)*" "copy (?!\\[.]$)(.*[\n]*)*" the closest can match first line of data after copy statement: "copy (?!\\[.]$).*[\n]+.*[\n]+" in general, want follows (note poses issues foreign key dependencies in cases: pg_dump -s mydatabase > dump.sql pg_dump -a -t table_i_want1 -t table_i_want2 -t table_i_want3 >> dump.sql the -s flag means --schema-only , -a flag tells "append" (i.e. data only).
