basically have php page want display data, want page downloadable , people can display locally. but! want add feature can check internet connection, connecting page's origin see if resources available such external style sheets etc. checking connection this: public function connection(){ const location='http://myresource.co.uk/'; $curl=curl_init(location); $result=curl_execute(); curl_close(); return($result==='i exist')?true:false; } now i'm bit stuck because want resources index display information. want use 'i exist' when checking resource. possible? or should use additional file sane person? xd this isn't going practically work because users typically aren't going have php installed. can allow them download php file.. sure unless have web server running it's not going work. on top of they'll need have curl extension etc.. see here check if extension loaded: http://php.net/manual/en/function.ext

i have huge file lines like insert mytable (),()... i'd replace lines beginning insert mytable by /* insert mytable (),()... */ i know there tons of possibilities, including vim search replace macro, i'd in command line. here's awk version: awk '{ gsub("^(insert.*)","/* & */"); print $0 }' this assuming insert first character on line. if there can leading spaces, use instead: awk '{ gsub("^([[:space:]]*insert.*)","/* & */"); print $0 }' this should work non-gnu awk's well. tested on linux , aix.

i writing web application dynamically inspect collections (publications) of ddp server. 1 of issues i'm running once meteor collection created sticks around lifetime of app: foo = new meteor.collection("foo"); however, depending on user application, might no longer interested in foo. wasteful have collection linger around, potentially end entire database being stored on client. the issue made worse fact client doesn't know collections going subscribe for. think causes issues how template helpers setup. examples i've seen far show helpers returning results of particular collection, like: return foo.find(); i still getting head around how reactive model works, i'm guessing if reassign foo: foo = new meteor.collection("bar"); ... above helper code not magically update return contents of 'bar'. update: since suggestions revolve around using combination of subscriptions , single collection i'd thought give context why as

on page 87 of the game boy cpu manual claimed cp n instruction sets carry flag when there no borrow , means a < n . seems conflict itself, because carry flag set when a > n . an example: if a=0 , b=1 , cp b sets flags sub a, b , 0 - 1. becomes 0 + 255 = 255 , carry flag not set, though a < b . i came across same issue in other z80 documents well, don't believe typo. am misunderstanding how borrow , sub work or there else going on? sub not equal add two's complement in terms of flags? the gameboy cpu manual has backwards. sub , sbc , cp set carry flag when there borrow. if sub/sbc/cp a,n executed carry set if n > a otherwise clear. this consistent z-80 (and 8080) operation. mame , mess implement carry the same way .

in eclipse can have multiple eclipse instances, each pointing different workspace. want 1 eclipse instance have lesser heap size other, because number of projects handles less , stuff run in requires less memory (this can reason). can set heap size in eclipse.ini using -xms40m -xmx512m options. but, changes heap size every eclipse instance start. don't want this. i want different heap sizes different eclipse instances. how achieve this? (i reckon in .metadata folder in workspace). you can specify ini file use --launcher.ini command line option when launching eclipse: --launcher.ini <location> (executable) the location of product .ini file use. if not specified executable file beside launcher same name , extension .ini. (ie eclipse.exe looks eclipse.ini, product.exe looks product.ini) you can either create different shortcuts or different .exe files, e.g. windows use path/to/eclipse.exe --launcher.ini eclipse-min.ini (or copy defaul
