i have website not have ssl (due cost reasons). has login form, why believe need ssl. however, don't store passwords, usernames; login form grabs posted username/password , sends via curl https-secured login form, returns yes or no, speak, server. given this, ssl certificate absolutely necessary, or there lower-cost alternative securing form? without using tls, username , password exposed listening in on traffic. this problem, because if website "low value", , doesn't matter if attackers able steal other people's credentials, people reuse passwords. so not protecting website, exposing users unnecessary risk. attackers can learn usernames , passwords, , try , re-use credentials {email,bank,work,etc} accounts. as others have pointed out, ssl/tls protects data in motion, not data @ rest. fact don't have sensitive stored data isn't relevant decision of whether protect traffic. as elon points out, can low assurance free tls certs better

i'm having issue calling .contains() on 1 of domain classes' hasmany relationships not doing same when running normally, or when debugging. situation follows: i have 2 domain objects, a , b . a has hasmany relationship b . class { ... static hasmany = [bees: b] ... } now, during execution of 1 of filters, grab current user spring security service. user contains single instance of b . filter should check if instance of b in user contained in instance of a . assume instances of b referring same object (since are). now, issue arises. calling: if (instanceofa.bees.contains(user.instanceofb)) { println 'success' } else { println 'failure' } prints failure during normal (or debugging without stepping through code) execution. however, if put break-point there, , step through code, correctly executes contains() , prints success . i have implemented equals , hashcode , compareto in attempt resolve this, same behaviour.

i'm wondering if can set value of html object's attribute string contains # character ? the reason want page have lot of items should scroll page specified elements, , want store data ' item should scroll to? ' data-scrollto attribute. so javascript code -will- this: function scrolltoelement(lm) { var thetop = lm.offset().top; $("html,body").animate({ scrolltop: thetop/*, scrollleft: 1000*/ }); } // .. , add click event such objects : $('.scroller').click(function(){ var theselector = $(this).attr('data-scrollto'); scrolltoelement($(theselector)); }); so html elements : <a class='scroller' data-scrollto='p#p-to-scroll'>click scroll p</a> is safe ? and side question, why $(element).data('scrollto'); does not work but $(element).attr('data-scrollto'); works ? according w3c specs, yes, is safe use u+0023 number sign

this may dumb question, deserialize json object pojo myobject field named class , reserved keyword in java... if possible, i'd keep myobject jackson/json/whatever-dependency free. do need add (standard or jackson-specific) java annotation class field member handle this? or there work-around have "pure" java object? can configure jackson object mapper if needed. public class myobject { public string field1; public string class; // fail } since class reserved java keyword, cannot use directly. if want generated json have it, use @jsonproperty , set value attribute. public class myobject { public string field1; @jsonproperty(value = "class") public string clazz; }

i'm not sure if question specific backbone.js. have model following render function: render: function() { var self = this; this.$el.empty(); this.model.fetch({ success: function() { self.$el.append(self.template(self.model.attributes)); } }); return this; } as can see, inside success callback function, use variable called self . because inside callback, this set window when want set view. there way can retain original reference of this without storing in variable? is there way can retain original reference of without storing in variable? yes, reasonable use case proxy method this.model.fetch({ success: $.proxy(function() { this.$el.append(this.template(this.model.attributes)); }, this) }); alternatively can use underscore's bind method: this.model.fetch({ success: _.bind(function() { this.$el.append(this.template(this.model.attributes)); },

how can use dynamic wsdl, it's operations , parameters, given in program config file? for example, have config file: [section] wsdl=http://example.com/somepub/ws/someservice?wsdl username=myuser password=mypass operationname=myoperation parametername=myparameter i.e. have use web-service, unknown, given (by ini-file) in run-time. so, cannot use wsdl import wizard in delphi. can write in delphi such program, load these settings configuration, , pass data specified operation in specified parameter on web-service, specified given wsdl? using soapui, import service , perform sample call. copy raw request , raw response notepad. modify real data 'tags' , include each raw template value in ini. when need make call, open ini, grab raw response template , replace tags real values. manually send soap request , parse response in same way using raw template.

the following code works fine in displaying process id of processes (eg: notepad.exe) running under different users. process under current user alone getting killed. need kill processes running under different users. #define sampleapp "notepad.exe" void main() { killprocessbyname(sampleapp); system("pause"); } void killprocessbyname(const char *filename) { // taking snapshot of processes handle hsnapshot = createtoolhelp32snapshot(th32cs_snapall, null); //structure capture each entry in snapshot processentry32 pentry; pentry.dwsize = sizeof (pentry); //capture first process in list bool hres = process32first(hsnapshot, &pentry); while (hres) { char tempprocess[process_size];// = pentry.szexefile; wcstombs(tempprocess, pentry.szexefile, process_size); //if process name equal process passed argument killed if (strcmp(tempprocess, filename) == 0) { handle hprocess

i want assign specific row , column range in matrix 1 , multipication of matrix original image multiplying image mask. in matlab used following code texture_mask= zeros(size(d_mask, 1), size(d_mask,2)); texture_mask(troi(1)-troi(3):troi(1)+troi(3),troi(2)-troi(3):troi(2)+troi(3))=1; im= im2double(im).*repmat(texture_mask, [1 1 3]); im= im(troi(1)-troi(3):troi(1)+troi(3),troi(2)-troi(3):troi(2)+troi(3),:); when try in opencv following code error in multiplication may beacause texture_mask not assigned properly. mat texture_mask= mat::zeros((dress_mask.rows),(dress_mask.cols),cv_64fc3); texture_mask.rowrange(troi[0]-troi[2],troi[0]+troi[2]).colrange(troi[1]-troi[2],troi[1]+troi[2])=1; img.convertto(img,cv_64fc3); img= img*texture_mask;//getting error here img=img.rowrange(troi[0]-troi[2],troi[0]+troi[2]).colrange(troi[1]-troi[2],troi[1]+troi[2]); after doing multiplication have crop image.as shown above.what wrong code??

this pretty broad question i'm hoping bit of guidance. i'm building reporting system company. have classes customer, order, invoice, , item. work great individual objects. however, reporting system , need query , summarize these objects in variety of ways. for example, single order object have total dollar value 1 order. if i'm generating report month, want summarize group of orders match whatever parameters pass query (such date range and/or customer number). this typically involves additional work such accumulating running totals month date or year date comparisons. things little fuzzy me. logic belong in order class? if not, where? note have same invoice class. here's simplified version of i'm doing order class. use 1 function (getorders) returns array of order objects, , function (getordergroup) returns array of grouped results (not objects). it's getordersgroup() function i'm unclear about. if there better practice reporting on grouped res

i use description attribute custom properties in wpf user control below. [category("features"), description("you can setup image width ratio in double type")] public double imagewidthratio { { return (double)getvalue(imagewidthratioproperty); } set { setvalue(imagewidthratioproperty, value); } } // using dependencyproperty backing store imagewidthratioproperty. enables animation, styling, binding, etc... public static readonly dependencyproperty imagewidthratioproperty = dependencyproperty.register("imagewidthratio", typeof(double), typeof(thecontrol), new uipropertymetadata(1.0)); the line [category("features"), description("you can setup image width ratio")] gives descriptions groups in properties window. but, windows store app user control. says no system.componentmodel.desriptionattribute . how show property descriptions in properties window in winrt? add he
