Perl's conditional operator in string context -

-
this question has answer here: why aren't newlines being printed in perl code? 3 answers let's take following minimalistic script: #!/usr/bin/perl # # conditional_operator.pl # use strict; print ( 1 ? "true" : "false" )." statement\n"; exit; i expect output "true statement". when execute snippet, see ... deviolog@home:~/test$ perl conditional_operator.pl true the " statement\n" concatenation seems ignored. my perl version v5.14.2. read perlop manual conditional operator , think, string concatenation should possible. can explain behaviour? always include use warnings; @ top of every script. to desired behavior, add parenthesis print called entire argument instead of first part: print(( 1 ?

i'm doing image processing using opencl. for example, used 100*200 size image. in .cl code, half image pixel value by: { int width=get_group_id(0); int height=get_group_id(1); // col(width) int x= get_global_id(0); // row(height) int y= get_global_id(1); (unsigned char) data_output[x*width+y]= (unsigned char)data_input[x*width+y]/2; } after kernel's parameter setting run kernel by: clenqueuendrangekernel( queue,kernel_dip,2,null,global_work_size,local_work_size, 0,null,null); the global_work_size used image size: size_t global_work_size[2] = {100,200}; i found .cl code doesn't include code "get_local_id(0);" the local_work_size did have lots influence on performance. both "size_t local_work_size[2]= {1,1};"(small local work size) , "size_t local_work_size[2]= {50,50};" (big work size) slow. some suitable size below faster: size_t local_work_size[2]= {10,10}; so here question: why code with...

html - Javascript addRule multiple selectors -

-
i'm experimenting addrule on css in html. works fine if this: document.stylesheets[0].addrule("#" + id + ':hover', 'max-height: ' + desiredheight + 'px;'); where id , desiredheight variables set. applies max-height when hover on element. question this: how can add structire this: body.link, body.appadd, body.pagelike { #id:hover{ overflow:hidden; maxheight: 400px; } } please ;) that structure has compiled down pure css before browser can understand it. so in particular case, like: document.stylesheets[0].addrule( 'body.link #'+id+':hover, body.appadd #'+id+':hover, body.pagelike #'+id+':hover, ', 'max-height: ' + desiredheight + 'px;' ); but if using id in 1 place recommended, you'll need (what have): document.stylesheets[0].addrule( '#'+id+':hover', 'max-height: ' + desiredheight + 'px;' );
