what these methods , how bad override them? irb(main):001:0> object::respond_to?('private', true) => true irb(main):002:0> object::respond_to?('public', true) => true the problem comes in rails when trying define scope named private or public model. because of fix bug https://rails.lighthouseapp.com/projects/8994/tickets/4167-activerecord-named_scope-using-columns-as-the-name-is-buggered there's lot of warnings like: creating scope :public. overwriting existing method mymodel.public. the public , private methods ruby's access modifiers. basically, when this: class example public def end private def something_else end end the public , private keywords not keywords @ all, they're method calls. i'm pretty sure it's not idea override them, i'd name scopes in other way.

i have mac os x app need store objective-c objects in stl containers (as pointers). works fine until compile program garbage collection "supported" due custom framework need use. problem objects stored in stl containers released. there way tell compiler not collect away , i'll release them when i'm done them? is possible? there way have framework uses garbage collection , main program doesn't? solve problem. can recompile framework, heavily relies on gc. you can disable garbage collection individual objects using nsgarbagecollector 's disablecollectorforpointer: method. hang around until call -enablecollectorforpointer: on it. i believe (but i'm not totally sure) can use cfretain / cfrelease on nsobject subclasses more or less same effect.

i'm trying verify x509 certificate using python. in particular need check crls when it. now, can use m2crypto this, can't find option corresponding openssl's -crl_check or -crl_check_all. alternatively, use pipe , call openssl directly: p1 = popen(["openssl", "verify", "-capath", capath, "-crl_check_all"], stdin = pipe, stdout = pipe, stderr = pipe) message, error = p1.communicate(certificate) exit_code = p1.returncode however, seems openssl verify returns exit code 0, have compare strings somehow tell if verification successful, i'd prefer not do. am missing simple here? thanks. ok, i've done this: p1 = popen(["openssl", "verify", "-capath", capath, "-crl_check_all"], stdin = pipe, stdout = pipe, stderr = pipe) message, error = p1.communicate(certificate) verified = ("ok" in message , not "error" in message) it...

occasionally, have following error stored procedure select query: transaction (process id 91) deadlocked on lock my initial understanding select query won't lock table, or won't cause deadlock if table tries query being updated/locked process, seems select query can cause deadlocks well. if set isolation level read uncommitted query, solve problem? my init understanding select query won't lock table, or won't cause deadlock this understanding wrong. select queries take shared locks on rows analyze. shared locks may conflict exclusive locks update/delete/insert statements. 2 select statements not going deadlock, select can deadlock update. when such deadlock occurs, select victim did not perform update going loose draw. as deadlock, need post exact schema of tables involved, exact t-sql statements , deadlock graph. see how to: save deadlock graphs (sql server profiler) . information can receive guidance how fix deadlock.

we use cobertura measure code coverage in unit testing , integrated/system testing. some classes more note suitable getting coverage in plain unit test. (some require database, gui testing etc). while mock objects, stubs, gui-unit-testing framework here, considering way mark classes not included in instrumentation. cobertura provides pattern based processing include/exclude classes. there way annotate class , skip instrumenting? without above, have write custom annotation processor list of classes, , user result skip instrumenting phase. if using ant run cobertura uses fileset use excludesfile parameter specify file containing list of files ignore. this list of files produced custom annotation parser or stick unique comment in files , search maybe like for file in `find ./ -name '*.java'`; if grep --silent "some unique tag" $file ;then echo $file > excludefile.lst; fi ; done

i'm aware property is descriptor, there specific examples of when using descriptor class might more advantageous, pythonic, or provide benefit on using @property on method function? better encapsulation , re-usability: descriptor class can have custom attributes set on instantiating. it's useful keep data confined in manner, instead of having worry getting set or overwritten on descriptor's owner.

i'm trying create javascript function (onmouseover) increase elements height , width 10px (1px increase 10 times settimeout), instead element increases 200px in height , 100px in width. doesn't make sense. example on how it's not working properly: www.modwebsolutions.com/test3/ source code: var el; function changesize(id) { var elem=document.getelementbyid(id); el=elem; (var i=0; i<10; i++) { settimeout(changes,100); } } function changes() { var tempheight=el.offsetheight; var tempwidth=el.offsetwidth; el.style.height=tempheight + 1 +"px"; el.style.width=tempwidth + 1 + "px"; } // update: tried el.style.height=(parseint(tempheight) + 1) +"px"; el.style.width=(parseint(tempwidth) + 1) + "px"; this time adds 50px height , still 100px width... instead of 10px each way. update: seems i'm gonna have answer own question, i'm still not sure, think has iterations running ahead of settimeout , messin...

what best way record mac screen cocoa? know there many examples @ apple developer reference library. sonofgrab explain how capture screen quartz isn't enough fast use grab many frames every second. openglscreensnapshot has same results isn't fast, too. openglscreencapture seems best way xcode prompts me many errors because it's made 10.4 , requires old quicktime commands think pushed qtkit can't find way convert it. send me someone's site converted project or tell me if there other ways it. in advance. opengl way go. should still able use openglscreencapture sample if architecture set 32-bit.

the system.exception class (actually exception) has data property empty. while throwing exceptions, should field of use? or have internal use not aware of? the documentation seems clear enough use (emphasis added): gets collection of key/value pairs provide additional user-defined information exception . why exist in first place? assume it's same reason control has tag property . in days of .net (before every bob , betty programmer understood objects , inheritance) wanted make api simple enough figure out how add data things. however, point of creating custom exceptions derive system.exception not include additional information, make possible client limit exceptions catch only can handle. if know how handle set of defined exceptions code can throw, should able only catch exceptions, without having catch base system.exception class. should never require client code catch non-specific exception class , read property determine type of exception (and whet...

so wanted implement timer in anroid program , found out better way using handler class. first decided write simplest program using handler - text set after 1 second. i'm totall beginner in android, went through tutorials on web 1 http://developer.android.com/resources/articles/timed-ui-updates.html , still application shows error ("application mtimer stopped"). so point out making mistake? gratefull, here's code: public class mtimer extends activity { textview tv; button button1,button2; handler mhandler; private runnable mytask = new runnable() { public void run() { tv.settext("text"); } }; @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.main); button1=(button)findviewbyid(r.id.button1); tv=(textview)findviewbyid(r.id.textview1); button1.setonclicklistener(new view.on...

cout << "how many questions there going on exam?" << endl; cout << ">>"; getline(cin, totalquestions); this small piece of code comes function in class have created , need totalquestions int can run through loop , keep asking total amount of questions have asked. question q; for(int = 0; < totalquestions; i++) { q.inputdata(); questions.push_back(q); } where piece of code comes play? have idea make work? use cin >> totalquestions; check errors too if (!(cin >> totalquestions)) { // handle error }

i'd able deploy staging , production environments vlad deployer. i've created separate task each environment, since each environment prepared differently. trying organize nginx configurations. should create 2 separate nginx configs, put them sites-enabled folder , include them in nginx.conf? i think depends on complexity of environments. files in sites-enabled folder allows have more clean structure. if have 2 servers , described 10 lines, isn't necessary.

i have options page in project , in can change password. have form asks enter current password , new password , confirm password . check data errors , send server using jquery ajax . the problem have need check current password against password stored in database. the database password hashed using php sha1($database_password.$salt); i thinking pass php variables, $database_password , $salt javascript somehow , use sha1() js alternative sha1 javascript code see if current password matches database password . can give me pointers or there alternative ways? i think it's better leave password hash on server. can ajax request current password , have server validate it. way hash remains unknown user , brute force attack more difficult. of course should send current password (and new password) once user indicates has finished typing (ie. when clicks submit button).

genericservlet implements servletconfig interface means interface functions can invoked init() function of genericservlet . given context, why servlet container sends servletconfig object init() method? know if servletconfig object passed genericservlet.init(servletconfig) different genericservlet object. regards, ravi the genericservlet implements servletconfig methods delegating config object passed init method. implements servletconfig convenience - delegates. instead of calling getservletconfig().getinitparameter() can call getinitparameter()
