i'd stamp variable generated gradle (in case it's user agent used later http requests) later able distinguish developer build app (for example if developer made mistake , app ddosing server). so can distinguish release debug with: buildtypes { debug { buildconfigfield "string", "user_agent", "\"android-debug\"" } release { buildconfigfield "string", "user_agent", "\"android-release\"" } } but debug i'd add know built app instance, may git login, machine name, or else. a gradle build file groovy code, , you're free put whatever want in it. have make sure code runs before used in dsl describes build. if want grab system, write groovy code that. groovy lot java, , have full jdk work @ runtime, should easy started. if want access things build machine , environment, might have shell out different commands in order gather data. populate v...

using lodash, have created array of pairs, each representing source , destination of link. given path of links, have: [ [a, b], [a, c], [d, c] ] it given first element first link in chain. wanted map pairs key/value map object , go through keys and/or values find head. simplified algorithm: keys.contains(a) || values.contains(a) if either returns true (excluding pair itself, naturally), not head. so, starting first pair, keys.contains(a) || values.contains(a) returns true not head, , keys.contains(b) || values.contains(b) returns false - must head. the problem: can't map pairs object, since there might key/value duplicates override each other. i.e., examples above, resulting object be: { a: c, d: c } i know can loop through them, reluctant many loops unless have to... any ideas of more efficient solution? i assume source key , destination value. roots of directed graph keys not occur value. (the leafs: vice versa). a root, d . b , c not. ...

im trying send users custom url's based on profile information. instead of sending user www.website.com/profile/john.doe want send them www.website.com/john.doe - when try remove "profile" portion of url. error saying the john.doe_controller.php file not found. unless im understanding wrong, dont want create new controller file every user. there .htaccess rule use this. thanx in advance. you can use following code in root/.htaccess : rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.+)$ /profile/$1 [nc,l,qsa]
