the andriod app i'm developing using http gets/posts using php files on website perform transactions on mysql database. on php side, wrap data json parse on java end of app when receiving response. modified 1 of tables , eliminated unnecessary values table. when poll using php scripts website, polls correctly. when use app, uses same php script polling, returns additional values removed database. i've restarted eclipse, cleaned project, , restarted android vdm refresh it; however, continues find values removed. ideas going on? here php script i'm connecting app: <?php mysql_connect("localhost", "******", "******"); mysql_select_db("bouncet2_pogoapp"); $query = "select * event_table order event asc"; $sql = mysql_query($query); while($row=mysql_fetch_assoc($sql)) $output[]=$row; print(json_encode($output)); mysql_close(); ?> as code in app using script: try { string response = customhttpclient.executehttpget(...

how convert month string integer? on click method want display date selected if date has event should display more event. method check holiday event requires integer values. here's code: updated: @override public void onclick(view view) { int m = 0; int d, y; string date_month_year = (string) view.gettag(); selecteddaymonthyearbutton.settext("selected: " + date_month_year); string [] datear = date_month_year.split("-"); log.d(tag, "date split: " + datear[0] + " " + datear[1] + " " + datear[2]); y = integer.parseint(datear[2]); try { calendar c1 = calendar.getinstance(); c1.settime(new simpledateformat("mmm").parse(datear[1])); m = c1.get((calendar.month) + 1); } catch (parseexception e) { // todo auto-generated catch block e.printstacktrace(); } //int m = integer.parseint(datear[1]); d = integer.parseint(datear[0]); log.d(tag, "date forward: " + d + " " + m + " " + y); if (isholiday(d, m,...

i wrote neural network object in python has cost function , determines gradients via back-propogation. see bunch of optimization functions here , have no idea how implement them. i'm having hard time finding example code learn from. clearly need somehow tell parameters i'm trying change, cost function i'm trying minimize, , gradient calculated backprop. how tell, say, fmin_cg what's what? bonus question: can learn differences in uses of various algorithms? ===== ok, update ===== this have atm: def train(self, x, y_vals, iters = 400): t0 = concatenate((self.hid_t.reshape(-1), self.out_t.reshape(-1)), 1) self.forward_prop(x, t0) c = lambda v: self.cost(x, y_vals, v) g = lambda v: self.back_prop(y_vals, v) t_best = fmin_cg(c, t0, g, disp=true, maxiter=iters) self.hid_t = reshape(t_best[:,:(hid_n * (in_n+1))], (hid_n, in_n+1)) self.out_t = reshape(t_best[:,(hid_n * (in_n+1)):], (out_n, hid_n+1)) and, error it's throwing: traceback (most recent call last): file ...

i use validationsummary(true) print model validation errors in 1 place , property validation errors near each field. in controller add property error : modelstate.adderror("property","error") i see message validation error property got validation-summary-errors div although have no model error. doing wrong , why div generated if have no model errors? <div class="validation-summary-errors"> <ul> <li style="display:none"></li> </ul> </div> you have add twice so: string errormessage = "the error message"; //will show in summary modelstate.addmodelerror(string.empty, errormessage); //will show prop modelstate.addmodelerror("prop", errormessage); or can change call so: @html.validationsummary(false) changing argument false include property errors. param name in validationsummary excludepropertyerrors , passing true excluding them.

this unrelated question code in this question , regarding following template function. template <class t> class object : public container { public: t& object; object(const t& obj) : object(obj) {} }; this code calls constructor: template <class t> void array::add_element(const t& element) { vec.push_back(new object<t>(element)); } this code compiles fine, add line in main calls it: array array; int = 3; array.add_element(i); i compiler warning: error: invalid initialization of reference of type 'int&' expression of type 'const int' . what about? passed int in. shouldn't automatically turned const int& me? why compiler complaining? obj const reference. object non-const reference. you can't initialize non-const reference const reference, because doing defeat purpose of having const reference in first place. if want instance of object able modify int that's passed constructor, constructor should take no...

i have image shown fig.1. trying fit binary image capped rectangular (fig.2) figure out: the orientation (the angle between long axis , horizontal axis) the length (l) , radius (r) of object. best way it? help. my naive idea using least square fit find out these information found out there no equation capped rectangle. in matlab there function called rectangle can create capped rectangle seems plot purpose. i solved 2 different ways , have notes on each approach below. each method varies in complexity need decide best trade application. first approach: least-squares-optimization: here used unconstrained optimization through matlab's fminunc() function. take @ matlab's see options can set prior optimization. made simple choices approach working you. in summary, setup model of capped rectangle function of parameters, l, w, , theta. can include r if wish don't think need that; examining continuity half-semi-circles @ each edge, think may sufficient let r = w, in...

how can have different layout depending on wether user logged in or not? follow instructions at https://github.com/plataformatec/devise/wiki/how-to%3a-create-custom-layouts , make check if user logged in, devise means checking user_signed_in? , devise helper. specifically: class applicationcontroller < actioncontroller::base layout :layout_by_resource protected def layout_by_resource if user_signed_in? "special_layout_name_for_logged_in" else "application" end end end and put special_layout_for_logged_in.html.erb view file in layouts directory.

as far can tell, answer no. issue i'm seeing comes include(params string[]) method in system.web.optimization.bundle class. internally invokes system.web.optimization.includedirectory(string, string, bool) , in turn uses code: directoryinfo directoryinfo = new directoryinfo( httpcontext.current.server.mappath(directoryvirtualpath)); while possible set httpcontext.current during unit test, can't figure out how make .server.mappath(string directoryvirtualpath) return non-null string. since directoryinfo(string) constructor throws exception when passed null argument, such test fail. what .net team's recommendation this? have unit test bundling configurations part of integration tests or user acceptance tests? i have news you, rtm added new static property on bundletable enable more unit tests: public static func<string, string> mappathmethod; edit updated test virtual path provider: so can this: public class testvirtualpathprovider : virtualpathprovide...

i have kiosk connects local socket server can access hardware. if kiosk code stored locally, can access socket perfectly. however, , know reason, if kiosk code hosted on remote server, can not access local socket server because of sandbox violation. the problem of these kiosks hosted on appengine, when done making changes, takes hours render out single html file, , change css/js location links. is there anyway possible allow swf file access local socket server when hostel remotely? also, socket server java app dont have source to. run locally through terminal i've had same problem. the thing flash player 10 security sockets has become stricter. placing crossdomain.xml on server won't - have send crossdomain policy file client connects. the simplest solution provided adobe - they've provided couple of scripts, 1 perl , 1 python, set policy file server. can find them here: setting socket policy server
