anyone know if it's feasible launch 'settings' app app? google maps when don't have location services enabled , try locate yourself. i've seen lots of folks post , answers point adding bug in radar. in wild, know of 2 apps show dialog ""turn on location services allow [app] determine location" along side cancel , settings buttons 'settings' button take general settings. 1) facebook app version 3.3.2 runs on ios 3.1.3 shows alert on start. looked @ three20 source code in git-hub project not full source of app more of library app's components. 2) groupme shows same alert when adding current location new message. you mean settings of app see in settings? first create settings.bundle in xcode>newfile>settings.bundle. create prop lists can edit out of settings.app or app self. exact code google can lot further can. if have specific questions; don't hesitate ask.

suppose in form, type within textarea character "ぎ" at momment of submit text , send page process (i.e. action="site.php" ): page send text encode text? or page recieve text? the point is: form send characters encoded(sequences of bytes) or characters encoded page recieve text form. is page encoded again when going sended form? cuz text typed not part of source code encoded. you'll want utf8 encode that look @ utf8_encode() , utf8_decode() you'll want multibyte-safe functions

i set cvs repository on server. then used eclipse sync repository local computer, using ext ( not extssh ). updates/commits eclipse work fine. however, when try commit or update using tortoise cvs, following error - cvs [checkout aborted]: end of file server (consult above messages if any). could tell me how solve issue? make sure paths set correctly. 1 thing learned hard way eclipse though added .jar files eclipse, when ran outside of eclipse, failed miserably because classpath variables not set correctly. i'm not sure if experiencing similar issue, may perhaps. i dig around bit , see if can find else in meantime.

i have simple rails 3 application users can reserve 1 of finite number of homogeneous items particular day. i'm trying avoid race condition 2 people reserve last item available on particular day. model (simplified) follows: class reservation < activerecord::base belongs_to :user attr_accessible :date max_things_available = 20 validate :check_things_available def check_things_available unless things_available? errors[:base] << "no things available" end def things_available? reservation.find_all_by_date(date).count < max_things_available end end the reservation being created in controller via current_user.reservations.build(params[:reservation]) it feels there better way this, can't quite put finger on is. on how prevent race condition appreciated. not sure answers question, might point towards solution: http://webcache.googleusercontent.com/search?q=cache:http://barelyenough.org/blog/2007/11/act

i'm looking @ implementing cram-md5 authentication imap , smtp server. problem cram seems require clear text password available @ times. server sends client unique challenge , client returns: md5( md5(password, challenge), md5( password ) ) i can't see way check without having clear text password, specification doesn't has have 1 available seems logical. the solution can come encrypt (properly encrypt, not hash) password database (probably using rsa key based aes, have deal that) , decrypt when need compare, seems slow way around though need decrypting , hashing every single login on smtp , imap. is best solution / efficient solution? or, better, cram out-of-date because less secure authentication on wire secured ssl now? the trick need unfinalized md5 of password same intermediate state of md5 context before finalizing. md5_ctx ctx; md5init(&ctx); md5update(&ctx, password, length); if , store value of ctx hashed , 1 can use copies of in

so, let's have large set of elements want attach event listeners. e.g. table want each row turn red when clicked. so question of these fastest, , uses least memory. understand it's (usually) tradeoff, know best options each. using table example, let's there's list of row elements, "rowlist": option 1: for(var r in rowlist){ rowlist[r].onclick = function(){ this.style.backgroundcolor = "red" }; } my gut feeling fastest, since there 1 less pointer call, memory intensive, since each rowlist have own copy of function, might serious if onclick function large. option 2: function turnred(){ this.style.backgroundcolor = "red"; } for(var r in rowlist){ rowlist[r].onclick = turnred; } i'm guessing going teensy bit slower 1 above (oh no, 1 more pointer dereference!) lot less memory intensive, since browser needs keep track of 1 copy of function. option 3: var turnred = function(){ this.style.backgroundco

on x86 linux, process a.exe invokes dlopen() load shared library b.so. in b.so, there's constructor, wants know function in process a.exe interrupted right before dlopen() invoked. how can constructor (_init section) in b.so know? if understand question correctly (the 'interrupting' might misleading), application has several locations might call dlopen() , want know of these locations called. first of all, smells wrong, because shared library should not supposed make assumptions loading it. if so, instance not run application in valgrind, because in case valgrind loading instead of standard dynamic linker , results might screwed. second, if need ( why? ), might take backtrace in constructor function. search upwards until find dlopen() , on next higher stack frame find function called dlopen. edit: map addresses in stack trace functions, need debug info of involved binaries or other way map function addresses symbol names.

i using protovis charts....i kind of new here... want want show area charts . , in want show few points different color or highlight point...and when click on point want open new page or show panel on same page...any idea how protovis? if not possible protovis can suggest other framework that? i think you're looking this: vis.add(pv.area) .data(data) .left(function(d) x(d.x)) .height(function(d) y(d.y)) .anchor("top").add(pv.dot) .size(20) .event("click", function (d) alert("clicked point " + this.index)); the important part .event("click", function (d) some_code()) bit. if you're using pure javascript, .event("click", function (d) { return some_code(); }) . here's working (albeit sloppy) example. you might want note protovis being superseded mike bostock's d3 .

while doing desing/framework usual practice have base class value objects, services, daos etc. example if create new vo, extends basevo. if create new dao, should extend basedao. reason why have such base class? inheritance, encapsulation , polymorphism, 1 of 3 primary characteristics of object-oriented programming. inheritance (inheriting base class) enables create new classes reuse, extend, , modify behavior defined in other classes. it easy add common methods , properties base class. that's not correct way cases. design patterns (like strategy pattern ) uses above mentioned oop concepts real designing.

in sql server, using "not exists" in queries considered bad practice , i've heard microsoft code reviews test not exists , flag these warnings. why not exists considered bad practice , join operators preferred on not exists? given that: any reasonably query optimizer able convert between “not exists”, “exists” , "joins", there no performance difference these days. “not exists” can easier read joins. therefore don’t consider “not exists” bad practice in general case.

i need bind date using milliseconds representation in controller (i.e. milliseconds 01.01.1970). tried using @as("s") had no success, fails value @ least 1000. there no way without writing custom binder? edit: seems writing custom binder way go because play's datebinder uses simpledateformat , because of this bug . simpledateformat doesn't accept these kinds of formats. afaik there's no way, because binder trying parse expecting date fields (and date millisec field 3 digit), , not calculate anything. it's better bind millisecs long , create date it.

i not trying such thing, wondering out of curiosity whether 1 implement "entire os" (not big linux or microsoft windows, more small dos-like operating system) in c and/or c++ using no or little assembly. by implementing os , mean making os scratch starting boot-loader , kernel graphics drivers (and optionally gui) in c or c++. have seen few low-level things done in c++ accessing low-level features through compiler. can done entire os? i not asking whether idea, asking whether remotely possible? obligatory link osdev wiki , describes of steps needed create os described on x86/x64. to answer question, gonna extremely difficult/unpleasant create boot loader , start protected mode without resorting @ least assembly, though can kept minimum (especially if you're not counting stuff using __asm__ ( "lidt %0\n" : : "m" (*idt) ); 'assembly'). a big hurdle (again on x86) processor starts in 16-bit real mode, need 16-bit code. acco
