i have posted code here . i new ember.js , still in learning phase.here trying build simple crud program. i trying use select in above crud program using ember.select not able use it. {{view ember.select contentbinding="objtype.content" valuebinding="objtype.selected" prompt="please select type" }} how use ember.select in above crud program create/update record? change this: objtype: ember.object.create({ selected: null, content: ['1', 2] }) to this: objtype: ember.object.create({ selected: null, content: ['1', 2] }) you should notice changed 'o' 'o', , need update select use right property name

i have list of operating systems. if enters "ubuntu", correct "linux ubuntu". have various other corrections , i'm wondering if there efficient way go through array making these corrections? i thinking of having associative array name , key pairs; key being "from" field , name being "to". there better way more efficiently? sample array: $os = array('ubuntu', 'vmware', 'centos', 'linux ubuntu'); the above values example of of data. of them correct, not though, , need corrected. what using array preg_grep ( string $pattern , array $input [, int $flags = 0 ] ) [1] kind less or more sophisticated regular expression? might need simple array of corrected (like linux ubuntu) values that. edit: code example crystal clearance: $regex = '/^[a-z ]*' . $user_input . '[a-z ]*$/'; $correct_values = {"linux ubuntu", "linux debian", "windows xp", ...}; //co

i participate in development of site has significant number of users view our site through aol desktop v9.7 windows - spawns browser windows inside itself. when debugging, don't have tooling able invoke (for example chrome's developer console ; firebug; msie's f12 developer tools ). when inside aol desktop, don't appear have of these, or similar. there developer mode or console can invoke, unearth? what meant in comments, use decent javascript debugger manual dom inspecting features, comes visual studio ( [edited] including free edition). tricks, work aol desktop, (what amusing piece of software is, btw :) of course, not same ie's f12 tools, lacks interactive features visual dom tree, css tracing etc. still allows step through code, watch locals , objects, evaluate expressions , access dom elements. it's invaluable tool , use lot projects host webbrowser control. after all, that's aol does, too. anyway, if you're familiar this, give post

i m installing subversion 1st time , have lot ofquestions. svn under /var/www/svn , on rot (/) has 50 gb of space. our devlopers might need lot of space 50gb. m trying create repositoies under /apps ( or install svn under /apps modifying subversion.conf file when access page saying forbidden. seems apache can access svn if under /var/www/. can me in solving issue. /apps filesystem has 1tb of space.and separate mount /. in httpd.conf file document root section probally says <directory "/var/www"> also can give apache ownership of directory if such placed in document root.

the documentation states default value buffering is: if omitted, system default used . on red hat linux 6, not able figure out default buffering set system. can please guide me how determine buffering system? since linked 2.7 docs, i'm assuming you're using 2.7. (in python 3.x, gets lot simpler, because lot more of buffering exposed @ python level.) all open (on posix systems) call fopen , , then, if you've passed buffering , setvbuf . since you're not passing anything, end default buffer fopen , c standard library. (see the source details. no buffering , passes -1 pyfile_setbufsize , nothing unless bufsize >= 0 .) if read glibc setvbuf manpage , explains if never call of buffering functions: normally files block buffered. when first i/o operation occurs on file, malloc (3) called, , buffer obtained. note doesn't size buffer obtained. intentional; means implementation can smart , choose different buffer sizes different cases. (ther

alright guys last little bit of project i'll ask on promise. go load images, works fine notice upon loading dimensions of image have been scaled down in y 300 (all constant value of 433) , or down original width 600. i'm using following method load them foreach (string file in directory.enumeratefiles(imagepath, "*.jpg")) { image contents = image.fromfile(file); treesimage[count] = contents; count++; } and resulting image when have loaded. http://i.stack.imgur.com/q40kk.png as can see image below red rectangle quite small any appreciated. if require more information please post below , i'll make sure edit original question relevant information humanly possible. edit: using simple windows form application , not graphical framework own reasons. in advance :) i'll assume using picturebox control display image. when chooses tree map, set picturebox image property image object referenced index in array. use image object set

i beginner using jpa 2.0 , databases in general , confused few concepts. have total of 3 tables. 1 usertable, contains information user. has primary key field called user_id. other 2 tables exercisestable , foodintaketable, , each have foreign key field called user_id reference user_id in usertable. want one-to-many relationship user_id table each of 2 tables can find pull out exercise information or food information user. pretty this: foodintaketable <-> usertable <-> exercisestable i need bidirectional mapping usertable foodintaketable , bidirectional mapping usertable exercisestable field user_id. the problem is, when try write code in usertable class: @onetomany(mappedby="exercisestable.userid") @onetomany(mappedby="foodintaketable.userid") public long userid; it's illegal because can't have 2 @onetomany annotations on same field. think it's supposed legal in normal relational database , i'm confused how translate jpa. i

ive noticed if field specified being not mandatory, when generate proxy class generate associated '[fieldname]isspecified' boolean related field. on using fiddler inspect request, if associated 'isspecified' set false, means field not sent on wires. i have 2 questions related 1.what point of this? purely minimize amount of data being sent across wire? 2.if no value passed parameter on webservice, wcf use default data type it. in case of integer field, default 0. once inside method how possible tell if 0 generated nothing being sent client field, or if indeed sent on 0? on question 2, specified fields not used only sending side. on receiving side, xml deserialiser set specified fields according presence or absence of corresponding fields on wire, allows service methods find out whether transmitted. as why want apart compactness of wire representation, example i've seen service allows update several fields in record @ once. in addition setting
