so i'm designing photo frame designer. can find here . want when 1 of patterns (under solid blocks of colour under text design) clicked text on frame changes have background pattern's image. understand svg uses fill attribute , need make pattern. @ minute. want this need able called on click. here code. can find full code on website though. <defs> <pattern id="patt1" patternunits="userspaceonuse" width="1246" height="1000"> <image xlink:href="images/pattern1.jpg" x="0" y="0" width="1247" height="751" /> </pattern> </defs> <text class="text" transform="matrix(2.4428 0 0 1.5 624.6 550.5599)" font-family="'comicsansms'" font-size="41.6368">your words here</text> and $("#pattern1").click (function() { $('...

trying achive like: command | { [[ ${pipestatus[0] == 0 ]] && cmd_pipe_success || cmd_pipe_failed ; } e.g. piping different commands, depending on exit-status. the above exmaple didn't works, e.g.: command_ok() { sed 's/^/ok /'; } command_no() { sed 's/^/no /'; } touch x ls -l x 2>&1 | { [[ ${pipestatus[0]} == 0 ]] && command_ok || command_no ; } rm x ls -l x 2>&1 | { [[ ${pipestatus[0]} == 0 ]] && command_ok || command_no ; } both prints ok , in both cases runs command_ok . is possible achieve run command_no when exit-staus of ls nonzero? i know, possible achieve like command_ok() { sed 's/^/ok /'; return 0; } command_no() { sed 's/^/no /'; return 0; } touch x res=$(ls -l x 2>&1) [[ $? == 0 ]] && command_ok <<<"$res" || command_no <<<"$res" rm x res=$(ls -l x 2>&1) [[ $? == 0 ]] && command_ok <<<"$res"...

a newbie here. apologize in advance grammar, not first language. okay, have form, , includes file field (which optional in validation) show picture user selected (before pressing submit). , yes, works. however, problem is, if go , press file field again, press 'cancel', unselect selected file shown image won't go away. way user won't confused if change mind selecting image. used javascript showing image after user selects. so here's code (i'll try exclude irrelevant parts): <script class="jsbin" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <script> function showimage(input) { if (input.files && input.files[0]) { var reader = new filereader(); reader.onload = function (e) { $('#newimage') .attr('src', e.target.result) .width(90) .height(90); ...

this question has answer here: how count possible combination coin problem 14 answers i have given array.and want find permutation of array sum specific numbers. example array =[2,3,5 ,1] target = 8 `solution: [2,2,2,2] ,[5,3] ,[3,3,2] ,[5,2,1] , possible combination please provide me approach solve problem , problem facing how handle repetition of elements.target large number of 10^6. think same as this theory you facing typical subset problem . worst case complexity of problem exponential no matter how put it. might find polynomial-time approximations work wonders average case though.

first time doing testing/using factory girl , i'm confused. i've got model called partnerships , has has_one relationship model called schools. partnership model: class partnership < activerecord::base has_one :school end school model: class school < activerecord::base attr_accessible :name belongs_to :partnership end school factory: factorygirl.define factory :school name "elementary school" end end partnership factory: factorygirl.define factory :partnership association :school factory :partnership_for_school after(:create) |partnership| partnership.school factorygirl.build(:school) end end end end in spec file, tried create simple test: describe "partnerships" "should able create partnership school" school_partnership = factorygirl.create(:partnership_for_school) school_partnership.school_id.should_not be_nil end end bu...

i notice idea has ability render "raw" type parameters in java in such way easier read. if have class class margininfo { margininfo( boolean top, boolean right, boolean left, boolean bottom ) { when calling it, actual code is new margininfo( true, true, true, true ); but renders as new margininfo( top: true, right: true, left: true, bottom: true ); once click on rendered code, rerenders actual code. after clicking code, if editing elsewhere stays actual code. there way idea have signature go rendering in "easier read" format after clicking? (also feature have name?)

while trying model polynomials, in particular multiplication, run following problem. during multiplication, individual monomials of 2 polynomials multiplied , of course in can happen have (3x^2 y + 5x y^2) * (x + y). result contains 3x^2 y^2 , 5 x^2 y^2, want combine addition right away. naturally use part x^2 y^2 of monomial key in (hash) map add different coefficients (3 , 5 in example). monomial object envisage should naturally contain coefficient, should not part of map key. of course write equals/hashcode of monomial object such ignore coefficient. feels wrong, because mathematically monomial equal 1 if coefficients equal. introducing coefficient-free monomial object intermediate operations not right. instead of using map, use list , use binary search dedicated comparator ignores coefficient. short of implementing map not use keys' equals/hashcode, dedicated one, there better ideas of how fuse monomials? consider using treemap , sortedmap and map . can...

i'm trying develop simple client / server game. server stores players data , sends them when requested or when data changes (player position, name etc) while client displays players connected server. graphic aspect simple: square representing player can move in 2d. i'm running server , client on ubuntu, while other client runs on windows. noticed when move windows player corresponding square moves smoothly on ubuntu side, while when move ubuntu square there lag when windows displays other pc's player. i thought happened because of bad connection or poor server optimization, because smoother client 1 running on same machine of server. but noticed if move both windows , ubuntu player, lag disappears , movement become smooth on both sides. this main method on client: public void render () { if(updatelistneeded && islogged) { //if game started update players list client.requestlist(); updatelistneeded = false; } player.update();...
