i have problem datamapper orm in codeigniter... :o my first model: class mil_widget extends datamapper { // insert related models mil_widget can have more 1 of. var $has_many = array( 'mil_relationship' => array( 'join_table' => 'mil_fields_mil_widgets' ) ); } and other model: class mil_relationship extends datamapper { // insert related models mil_widget can have more 1 of. var $has_many = array( 'mil_widget' => array( 'join_table' => 'mil_fields_mil_widgets' ) ); } if di works , saves right database entry: $w = new mil_widget(1); $r = new mil_relationship(1); $w->save($r); but if error: $w->mil_relationship->get(); and error: datamapper error: 'mil_widget' not valid parent relationship mil_relationship. relationships configured correctly? thank you!

i'm making app coreplot , trying labels along xaxis read 12pm , 1pm, 2pm, etc. have implemented nsdateformatter xaxis.label formatter. problem is, intervals appear in seconds (see pic below) need them in hours. i tried fix making xaxis.majorintervallength 3600, makes graph this: the tick stil there, they're placed 3600 placed apart, if makes sense. here code: cptxyaxisset *faxisset = (cptxyaxisset *)self.graph.axisset; faxisset.xaxis.title = @"time"; faxisset.xaxis.titletextstyle = textstyle; faxisset.xaxis.titleoffset = 30.0f; faxisset.xaxis.axislinestyle = axislinestyle; faxisset.xaxis.majorticklinestyle = axislinestyle; faxisset.xaxis.minorticklinestyle = axislinestyle; faxisset.xaxis.labeltextstyle = textstyle; faxisset.xaxis.labeloffset = 3.0f; faxisset.xaxis.majorintervallength = cptdecimalfromfloat(3600.0f); faxisset.xaxis.minorticksperinterval = 1; faxisset.xaxis.minorticklength = 5.0f; faxisset

so i've made database of guilds of mmo. people can go there , filter gaming guilds based on numerous different options , displays in nifty table. example: guild name - focus - leaders guild 1 - pvp - bob guild 2 - pve - fred now want make guild name link takes user guilds page. page doesn't exist until person clicks on link, create temple called viewguild.php , if person clicks "guild 1" takes them http://somesite.com/viewguild.php?name=guild1 . , have done! using code: echo '<tr><td><a href="viewguild.php?id='.$guild2.'">'.$guild2.'</a></td>'; it creates link fine! problem is, can't seem php file, viewguild.php, generate information based on guild name person clicked. you can use $_get['id'] variable in viewguild.php name of guild in url.

i have following scenario: i'm developing java ee web application running on jboss 6.1.0 , want publish application on public server end-user testing. for example: http://mysite.com/testings/app1/ my question: appropriate way protect directory in .htaccess (apache http server) fashion, so, when client try access http://mysite.com/testings/app1/ asked user/password combination?. i think there 2 options: configuration on servlet server? reverse proxy?. i want clarify best practice in situation, because php applications .htaccess feature fit needs. you can use spring security that, wrote example in how do http basic auth using struts 2/ spring 3? . or can use apache httpd server "above" jboss (using rewrites , proxy) users access site via apache, , apache forwards jboss (that listen on localhost). here example rewrite rule forward "www.mysite.com" web application "myapp" ajp connector on port 8009: <virtualhost www.mys

our teacher wants print @ matlab graph plots, in x axis , quality factor , , on y axis mean square error . image known "lenna.jpg". i've searched , found how find mse, didn't find helps me on how find quality factor. so, can please tell me in matlab code, how find these 2 things , how display them in graph? thanks in advance. i don't have matlab available right now, think following should work: original=imread('lena.jpg'); mse=zeros(1,100); q = 1:100 tempfile = sprintf('lena%03d.jpg', q); imwrite(original, tempfile, 'quality', q); thisone = imread(tempfile); mse(q) = sum((original - thisone).^2)/numel(thisone); end figure plot(1:100, mse) xlabel 'quality factor' ylabel 'mse' title 'degradation of lena.jpg quality factor'

i'm trying pull similar data in several third party apis, of have varying schemas, , convert them unified schema store in db , expose through unified api. re-write of system this, minus storing in db, hard test , not elegant. figured i'd turn community wisdom. here thoughts/what i'd achieve. an easy way specify schema mappings external apis schema internal schema. realize nuances in data might lost converting unified schema, that's life. schema mapping might not easy , perhaps overkill academic papers i've found on matter. an alternative solution allow third parties develop interfaces external apis. code quality of these third parties may or may not known, established via thorough tests. therefore system should easy test, i'm thinking mocking external api calls have reproducible data , ensure parsing , conversion being done correctly. one of external api interfaces crashing should not bring down rest of them. some sort of schema validation/way detec

my task draw 1 sprite 100 times in frame. example need draw row made of 1 sprite "sprite.png". this: ccsprite *spritearr[ 100 ]; ( unsigned int = 0; < 100; i++ ) { spritearr[ ] = new cocos2d::ccsprite(); spritearr[ ]->initwithfile( "sprite.png" ); spritearr[ ]->setposition( cocos2d::ccpoint( * 10, 100 ) ); this->addchild( spritearr[ ] ); } and that's problem. allocate memory 100 times 1 sprite don't know how differently. how can optimize it? there way in cocos2d drawing sprite using coordinates (x , y) not allocate memory each same sprite? you're good. 100 sprites reference same texture object, it's single texture in memory. each sprite instance adds less 500 bytes of memory on top of that. your best option conserve memory use .pvr.ccz format images.

i understand vcard 4.0 introduce commonly used contact property fields (types) gender, anniversary, etc. there no standard way represent these in vcard 3.0 format. my question should client if vcard 3.0 object contains gender type. make invalid vcard, or clients ignore fields? some clients add x-gender property. however, since it's extended property, there's no guarantee application reading vcard detect it. x-gender:male source: http://en.wikipedia.org/wiki/vcard#vcard_extensions you go ahead , include gender property, though it's not part of 3.0 specs. specs if vcard contains property consumer not recognize, consumer must ignore property , continue parsing rest of vcard.

it possible extract executable files?? if possible software may use? it depends how deep want dig executable , kind of data need exe. exe files can analyse them on low level. assume want have high-level tool director files used create exe, right? exe-file (the "projector" use appropriate director wording) there no such tool known me. but exe file used files extensions such .dxr or .dir. director files. dxr-files protected. importing them director can extract of cast memebers (graphics etc.) included. need in-deep knowledge of lingo so. you might find .cst or .cxt files. cast files. can hold media, scripts etc. too. cxt protected versions. these files same true dxr , dir files. all in - not easy , chances low completly reveal code , media. director programmer use protected files distributing programs. not allow reveal data included.

i'm printing stacks c code using backtrace_symbols() (following instructions on http://www.gnu.org/software/libc/manual/html_node/backtraces.html ). however, can addresses of stack frames in dynamic library though built library using -g -rdynamic . now, have running process , have library, how find out method each frame address corresponds to? thank in advance. this on 64bit linux. the example of print out looks this: obtained 9 stack frames. /tmp/libexample.so [0x2aaabaae9771] /tmp/libexample.so [0x2aaabaae9828] /tmp/libexample.so [0x2aaabaaa8138] /tmp/libexample.so [0x2aaabaab2402] /tmp/libexample.so [0x2aaabaabd029] /tmp/libexample.so [0x2aaabaa1e23a] /tmp/libexample.so [0x2aaabaa24ded] /lib64/libpthread.so.0 [0x30b700677d] i think you're looking dladdr function.

does declaration in c# allocate memory variable created or new operator allocates memory , enables invoke constructor initialize allocated variable in memory? to understanding, cannot call constructor of type without new operator. correct? does declaration in c# allocate memory variable created or new operator allocates memory , enables invoke instructor initialize allocated variable in memory? first let's make sure you're asking question think you're asking. value type, variable storage location , value storage location the same storage . reference type, storage location associated the variable contains reference storage location associated the object . different. second, let's clarify mean "declaration" of "variable". static field, instance field, local variable , formal parameter have declarations. moreover, allocation semantics of local variables , formal parameters different if closed-over outer locals of lambda, , se

i'm trying compare multiple lists. lists aren't label...normally. i'm using while loop make new list each time , label them accordingly. example, if while loop runs 3 times make list1 list2 , list3 . here snippet of code create list. for link in links: print('*', link.text) locals()['list{}'.format(str(i))].append(link.text) so want compare each list strings in them want compare lists @ once print out common strings. i feel i'll using this, i'm not 100% sure. lists = [list1, list2, list3, list4, list5, list6, list7, list8, list9, list10] common = list(set().union(*lists).intersection(keyword)) rather directly modifying locals() (generally not idea), use defaultdict container. data structure allows create new key-value pairs on fly rather relying on method sure lead nameerror @ point. from collections import defaultdict = ... link_lists = defaultdict(list) link in links: print('*', link.text) link_

is there rule of thumb or mathematical equation tells me how wide (1d discrete) gaussian kernel should sigma? lets say, choose sigma of 1.87, should kernel 5 values/steps/pixels wide, 7 oder rather 25 in order perform standardized image smoothing? thank you. pick threshold consider ignorable, t = 0.01 . solve exp(-x^2/(2s^2)) / sqrt(2pi s^2) < t : |x| < s sqrt(-2 ln(sqrt(2pi s^2) t)) the right hand side gives width. s = 1.87 , t = 0.01 , gives width of 4 pixels.
