anyone know of workaround phpunit's illogical file sorting? i've got tests in subfolder names "addmin001.php", "...002.php", etc. , phpunit insists on running 002, 003, 004, 001. my attempts use phpunit.xml produce: "uncaught exception 'phpunit_framework_exception' message 'could not load "[redacted]phpunit.xml".' in /usr/share/php/phpunit/util/xml.php:212". creating alltests.php classes seems lot of work , maintenance, if necessary i'll go route. phpunit not sort tests @ all, run in whatever order filesystem returning them. creation date, else, depends on filesystem (and os) in use. in case, can not rely on order, because factors outside tests can change it. there few tricks, use - example test dependencies .

i going coach student career software tester or software test manager. have suggestions, interview questions should prepared? thank in advance. i'd ask - "how test 'this'?", 'this' relevant work - or @ least know lot about. example, ask "how test web browser?". you'd want see if had nice battery of functional test ideas, idea of big picture or (as stated above), non-functional areas such performance, reliability, security, etc. i'd ask them questions communication - e.g. "give me example of how resolved conflict co-worker". testers "bearers of bad news", interpersonal skills, ability communicate peers critical. can examples of using data make decisions, or influence without authority valuable. finally, ask "how learn?" - testing learning activity, ability - , demonstrated experience in quick learning sign of successful.

i apologize if has been asked before. search results did not turn similar question. this conceptual question. according msdn , others well: a constant member function cannot modify data members or call member functions aren't constant why allowed access static member variables const method? the c++ standard says const member functions: if member function declared const , type of const x* , [...] in const member function, object function called accessed through const access path; therefore, const member function shall not modify object , non-static data members. so see non-static data members part of 'constness' of member function. however, think more importantly indicates way understand what's going on const member functions makes implicit this pointer pointer const . since static members don't need accessed via this pointer (implicitly or explicitly), access them isn't const qualified.

recently i've studied backpropagation network , have done manual exercise. after that, came question( maybe doesn't make sense): there thing important in following 2 different replacement methods: 1. incremental training: weights updated once delta wij's known , before presenting next training vector. 2. batch training: delta wij's computed , stored each exemplar training vector. however, delta wij's not used update weights. weight updating done @ end of training epoch. i've googled while haven't found results. so referring 2 modes perform gradient descent learning. in batch mode, changes weight matrix accumulated on entire presentation of training data set (one 'epoch'); online training updates weight after presentation of each vector comprising training set. i believe consensus online training superior because converges faster (most studies report no apparent differences in accuracy). (see e.g., randall wilson & tony martine...

lets imagine site embeds javascript file using standard script tag pointing server b. next site makes jsonp or ajax request resource on server b. there anyway server b definitively know specific jsonp request originated user on site a, , not user on site spoofing http referrer. the reason think there realm of possibility because site started communication it's embedding of server b's javascript. in way, couldn't original communication act security handshake, allowing subsequent calls pass through securely. because handshake made through insecure means doesn't prevent acting security handshake. any ideas of how task can accomplished? every solution can think broken notion every element of ajax call can faked. i read http://www.codinghorror.com/blog/2008/10/preventing-csrf-and-xsrf-attacks.html , detecting ajax in php , making sure request own website far tell focused on ensuring veracity of user , not veracity of referrer. ajax on https if wanted con...

can change siz,style,etc of font (javax.microedition.lcdui.font) in j2me @org.life.java true there isn't set size method..... being said there isn't "setsubstring" method either. strings fonts in j2me immutable http://en.wikipedia.org/wiki/immutable_object create new font desired properties.... http://download.oracle.com/javame/config/cldc/ref-impl/midp2.0/jsr118/index.html so instead of myfon.setsize(font.size_small) do myfont = font.getfont(myfont.getfontface(), myfont.getfontstyle(), font.size_medium) that work.

possible duplicate: could explain sta , mta? in c# windows forms application. have seen [stathread] in program.cs above main function. so want know when use sta or mta thread ? how, affects application ? a thread creates windows should always create single-threaded apartment. sta provides threading guarantees com object isn't thread-safe. few are. com infrastructure ensures methods of such object called right thread, marshaling call if necessary. quite similar control.begin/invoke() done automatically without coding. a number of windows facilities rely on guarantee. notably clipboard, drag + drop , shell dialogs (like openfiledialog) won't work without it. , lots of activex controls, webbrowser being common 1 you'll use in winforms project. making ui thread mta thread causes hard diagnose failure, deadlock being common one. or quick exception when .net wrapper component double-checks created on sta.

by default : registry has been disabled "registry editing has been disabled administrator" in application want let users access registry when app runs , deny when app stops. looking forward advice on this. to allow users edit registry settings not accessible, need use impersonation. i.e. need have application run different user, 1 more priviledges. the easiest way achieve write .net windows service runs higher priviledges. service can still control registry settings allowed change. users start winforms app communicates service actual changes in registry. this require user (or operations) install service on machine admin rights.

i've implemented tryparse function class minmax this: public static bool tryparse(string s, out minmax result) { var parts = s.split(' '); if (parts.length != 2) { return false; } float min; float max; if (!float.tryparse(parts[0].trim(), out min) || !float.tryparse(parts[1].trim(), out max)) { return false; } result = new minmax(min, max); return true; } however doesn't compile since apparently out parameter needs written. what's correct way fix this? able use function if parsing fails, parameter passed remains unchanged. guess 1 way add like: result = result; but line issues warning. assuming minmax reference type, assign null it. other tryparse method work. check out code: string s = "12dfsq3"; int = 444; int.tryparse(s, out i); console.writeline(i); i set 0 instead of remaining @ 444. ...

does have tips/resources how to, in best way, structure c code projects? (different folders etc.) , how know when it's split code separate files? , example of makefile? my project not big, wanna start structure code @ stage.. structuring code needs experience common sense. for splitting code, go readability: conceptually coherent functions/datatypes should go in same file. can take c standard library example. better keep data structure definitions , function declarations in separate headers. allows use data structures part of compilation unit if have not defined functions. files provide similar functionality should go in same directory. avoid deep directory structure (1 level deep best) complicates building project unnecessarily. i think makefiles ok small projects, become unwieldy bigger ones. serious work (if want distribute code, create installer etc) may want @ cmake, scons, etc. have @ gnu coding standards: http://www.gnu.org/prep/standards/standards.htm...

i have small sdi application trying add tracking of menu usage, ie. how many times menu items selected user. some menu items handled view component (demoview.cpp) , others main app (demoapp.cpp). since tracking structure defined in main app, believe have notify view's parent special message when menu item (handled view) selected. if correct, problem cannot create proper on_message command. looks : on_message(wm_increase_freq, &cdemoapp::onincreasefreq) where onincreasefreq() defined : lresult cdemoapp::onincreasefreq(wparam, lparam) however error : error c2440: 'static_cast' : cannot convert 'lresult (__thiscall cdemoapp::* )(wparam,lparam)' 'lresult (__thiscall cwnd::* )(wparam,lparam)' i appreciate this according error, callback function must member function of class derives cwnd. make cdemoapp derive cwnd , code should compile , work.

i made pseudo code algorithm find repeating values of array includes float numbers: mergesort(a); int <- 0 i<- a.lenght-1 if arr[i] == a[i+1] return a[i] while a[i] = a[i+1] i++ else i++ i want change above algorithm find repeating values , number of times repeat. have created following algorithm: mergesort(a); hashmap hashmap; int result <-0 int <- 0 i<- a.lenght-1 int j <- 0 if a[i] == a[i+1] j <- j+1 result <- a[i] while a[i] == a[i+1] <- i+1 j<- j+1 hashmap.insert(result , j) else i++ return hashmap is efficient algorithm? way use hashmap? you can use hashmap , this: hashmap hash; (int = 0; < a.lenght; i++){ value = hash.get(a[i]); if (value == null) // first time find a[i] hash.put(a[i], 1); else // a[i] duplicate hash.put(a[i], value + 1); } avarage case = o(...

i wondering using css sprites tag html best? i mean can use < img src="trasparent.png" style="background-position:ecc"> or ? i saw google using < span> "o" of g"o o o o o"gle thanks you can use element like. one thing note though elements <span> , <a> inline elements. if try , add dimensions them match size of background sprite, these dimensions ignored. fix can use things line-heights or padding set dimensions, or change element block level element using css: display:block . another rule allow dimensions added display:inline-block , can cause few issues in ie6 , earlier browsers.
