looking best way accomplish below. want return true if empty in user object, don't care 1 empty. think i've done before searching empty values in array can't think of best way objects. i know can loop thru object , break once find empty value in object, checking first see if there better way of doing this, thanks! function is_it_empty($user) { $is_it_empty = false; if( isset($user->first_name) ) $is_it_empty = true; if( isset($user->last_name) ) $is_it_empty = true; return $is_it_empty; } also: function name($user) { foreach($user $u): if( isset ($user->value) ): // or should isset? return true; break; endif; endforeach; return true; } $user = new stdclass(); $user->firstname = 'mark'; $user->lastname = 'baker'; $user->sanity = null; function is_it_empty($user) { foreach($user $property) { if (empty($property)) { return true; } } return false; }

i working on document recommendation program , kinda stuck here. each document, have score assigned according user's actions. then, when new document comes in, need predict how user , rerank whole documents again according scores. solution use threshold divide scores "recommend" , "not recommend". naivebayes or other classification models can either give me label or return possibility of label (i using nltk package text analytics). on right way? question when possibility, how can convert score use ranking? or should use logistic regression in scikit instead? thanks! i suggest trying out svm-rank algorithm. takes input set of "recommended" , "not recommended" vectors , learns how rank them recommended ones come first. there simple python tool in dlib can use it. see here example: http://dlib.net/svm_rank.py.html

so i've been struggling trying add audio slider game last couple days , i've had it, so, let me preface saying have tried extremely hard , love understand solution, @ point want solution, more specific can better. i've thought of number of approaches, actionscript skills have been faulty pull of them off. let me explain setup bit. have functional class audio slider. plays music, slides, perfect. now, i'm sticking in document class. thought easiest call function right @ beginning (as title screen shows up), though don't want music playing right @ title screen. thought call it, not play music yet. have called document class. now, want able click on options button , addchild audio slider. have accomplished , works. finally....the hard part. want click play game button , have music start playing while being linked options slider has possibility of being moved. really...just standard audio slider. i'm stuck on linking options screen audio slider music playing

the target application can used in "pipe" mode, means accepts input stdin, , can output stdout. however, there risk of user making mistake, directing output stdout, without directing stdout towards "something" (a file, or consumer program). consequence, console screen gets garbaged displaying binary data (since default, stdout outputs screen). bottom line : want avoid binary output displayed console, automatically. must done in portable c , , not depend on external script. a few potential ways of doing : 1) possible detect stdout going console, in order redirect somewhere else instead ? (including /dev/nul). note code must portable, , work windows , linux (and bsd, opensolaris, etc.) 2) alternative : possible redirect stdout "somewhere else" (such /dev/nul) default without harming correct usage of program, redirecting stdout valid consumer process ? on posix (e.g. linux , osx) system can use isatty function check if stdout goes co

let's have base template header in it, , content of header needs passed template. <header> logged in {{ name }} </header> this base template gets extended many pages. how can pass in variable without passing each individual child? example, don't want have this: render_template("child1.html", name=user.name) render_template("child2.html", name=user.name) render_template("child3.html", name=user.name) etc... because knows how many child pages might have. doesn't feel dry enough. i never render base template, children, don't know how else pass in data. is there way this? should not using inheritance? may suggest use global variable 'g' in flask. default available in jinja templates. don't need worry passing anywhere in base template or children. make sure set first when login g.username = user.name then in templates, this: you logged in {{ g.username }}

i have simple web api project based on example: http://aspnet.codeplex.com/sourcecontrol/latest#samples/webapi/relaysample/program.cs however, in above sample relay working local server, in project relay working external web server real address; companyx.com i using relay service (or, web proxy service) through browser, example, in browser request relayservice.com/companyx. relay service responds data external companyx.com site. the relay works great, headers not correct , need see httpclient sending remote companyx.com server. in fiddler or charles, request/response browser relayservice.com listed, request/response httpclient relayservice.com never shows up. the relayservice.com running locally on machine, in iis7, i'm using hosts file direct traffic relayservice.com. i have tried several variation of following when creating httpclient: var clienthandler = new httpclienthandler { cookiecontainer = cookies, usecookies = tru

in situation when have conditional server code, visual studio keeps auto-renaming duplicate id's. here's valid example: <% if x = 1 %> <input type="hidden" id="hello" value=""/> <% else %> <input type="hidden" id="hello" value=""/> <% end if %> when visual studio's live error checking finds this, change code without confirming me following: <% if x = 1 %> <input type="hidden" id="hidden1" value=""/> <% else %> <input type="hidden" id="hidden2" value=""/> <% end if %> how turn off? don't mind turning off whole live error checking even. don't know toggle "feature" though. thank reading question, go tools -> options scroll down text editor. expand it, select html , expand it. click miscellaneous , should see following. deselect first option , try i

i have return json string in c# api follows like: { "model" : 4 , "lang" : "en_us", "parts" : [ { "id" : 1545, "name" : "part 1", "part_types" : { "type 1" : { "url" : "part.com/type1", "desc" : "has 6 bits" }, "type 2" : { "url" : "part.com/type2", "desc" : "has 7 bits." } } } ] } i have basic structure like: public class inventory { public int model { get; set; } pub

i want rebind existing function after draggbale item dropped, like: .item draggable item, , .droppable droppable area. i running function .droppable s .item on .ready() , if drop .item .droppable existing function not work newly dropped .item , put event inside function, like: function my_event(){ jquery('.droppable').on('mouseover.mine mouseout.mine', function (e) { if ($(this).is(".active")) { e.stoppropagation(); e.preventdefault(); jquery(this).toggleclass('highlight'); } }).on('click.mine', function(e){ if ($(this).is(".active")) { e.stoppropagation(); e.preventdefault(); show_data(this); } }); }); } now, can call function on .ready() , .droppable() event stop . working fine, but want ask right call , rebind function after every .item dropped

started write question, while wrote question, answer. not delete content, post answer (possibly may useful). , may there improve. based on https://stackoverflow.com/a/15048890/2465936 answer trying sum values in 1 column , group values in other column for example, table named 2_1_journal transactionpartnername | amount ------------------------------- name 1 | 1 name 2 | 2 name 1 | 3 name 3 | 10 name 2 | 7 name 1 | 150 as result want this name 1 = 154 name 2 = 9 name 3 = 10 mysql query $query_select_all =" select transactionpartnername, sum(amount) 2_1_journal group transactionpartnername"; then $sql = $db->prepare($query_select_all); $sql->execute(); $sql = $sql->fetchall(); with print_r($sql); get array ( [0] => array ( [transactionpartnername] => name 1 [0] => name 1 [sum(amount)] => 154.00 [1] => 154.00 ) [1] => array
