what i'm trying save changes make css , html on different sites firebug. just clear, don't expect firebug upload changes server via ftp or anything. want save changes locally, able see them. for example i've seen few firefox/chrome extensions add download button under every video on youtube, know it's possible somehow. if have different way achieve i'm trying do, i'll glad hear it. (it doesn't have firebug.) thanks in advance! you try using greasemonkey . it has support adding custom scripts run whenever load page (linked pages should load on) , can make changes page dynamically. https://addons.mozilla.org/en-us/firefox/addon/greasemonkey/

are there issues, compile time operator, sizeof associated new? new operator can overload (or all) of classes. edit: i'll try clarify address @sbi's comments below. consider 2 classes: class base { } class derived : public base { } let's assume new() function, , want specialize base class , descendants. have "basic" new() function: void *new(size_t size); overloaded functions cannot differ return types alone, can't do: base *new(size_t size); // illegal. we can't use member functions because need existing instance called. use static member functions: class base { static base *new(); } but resulting syntax when allocating instance of derived quite awkward: derived *derived = base::new(); // uh?

i have index documents have 2 fields (actually more 800 fields other fields won't concern here): the contents field contains analyzed/tokenized text of document. query string searched in field. the category field contains single category identifier of document. there 2500 different categories, , document may occur in several of them (i.e. document may have multiple category entries. results filtered field. the index contains 20 mio. documents , 5 gb in size. the index queried user-provided query string, plus optional set of few categories user not interested in. the question is : how can remove documents matching not query string unwanted categories. i use booleanquery must_not clause, i.e. this: booleanquery q = new booleanquery(); q.add(contentquery, booleanclause.must); (string unwanted: unwantedcategories) { q.add(new termsquery(new term("category", unwanted), booleanclause.must_not); } is there way lucene filters? performance issue here,

i have 2 panels, , when first panel scrolled, want other 1 scrolled, how do that? thanks in advance :). you can listen scrollablecontrol.scroll find out when it's scrolling. unfortunately don't know of easy way make other 1 scroll correct location, think should able sending wm_vscroll or wm_hscroll using sendmessage api function. depending on contents of panels might able "cheat" setting autoscroll true , whenever first panel scrolled, set focus suitable control in second panel outside visible area , make scroll there. i'm not sure how work or if easier doing (if want scroll extreme sides of panel, might useful).

i want access tts (text-to-speech) , stt (speech-to-text) functionality of ios web app. since web app dont access ios device functions, possible launch native app web app? e.g. when user wants access tts (e.g. dragon dictation), web page launch native app, take recording , send recorded text web app again. or can access tts/stt functionality right web app? the native apps can access web apps custom url schemes set up, , built-in ones e.g. sms ( sms:// ), phone ( tel:// ), itunes ( itms:// ) , youtube ( http://youtube.com/watch?... ). if apps mention don't have own custom url schemes can use them, there's no other way can this.

i've been profiling asp.net application ants memory profiler 6, , have seen indications of memory leaks. however, don't know whether or not growths i'm seeing supposed there or not (for instance, system.string grows lot each snapshot. should it?) i don't understand whole memory processso don't know if interpreting results correctly or not. how interpret results of ants memory profiler? i have kind of been able answer own question while solving memory issue. although string may on top of list of time, shouldn't see instance count keep growing , growing. turns out in applcation object thought being free'd wasn't held reference xml files of course held in strings. my test go home page of web site -> click page -> home page. doing should mean no new references should have been created (instance count should remain 0 (no growth)). hope can else.

i never came in touch perl before, hope, real newbie question , can solve problem pretty quick... we've 1 perl based web application installed on windows 2003 server environment. installed version contains bug , know where apply patch. basically: have changed 2 lines in 1 of web apps pm files. to surprise, file change ignored , still same error messages references old version of file - identifiable line numbers. i've cleared browser caches, restarted web application (including apache) - no luck. now think/hope kind of perl feature, don't know enough of language ask google right questions. one tutorial said, perl interpreted language , changes source files effective immediately. isn't true site... are there more caches/files have touch or delete in order make changes effective? are sure perl using latest version of said pm file? there no other version somewhere else included getting used? take @ @inc step through programming using debugger

how can convert string byte value? have string "hello" , want change "/x68..." . python 2.6 , later have bytearray type may you're looking for. unlike strings, mutable, i.e., can change individual bytes "in place" rather having create whole new string. has nice mix of features of lists , strings. , makes intent clear, working arbitrary bytes rather text.

i have script open model window.. chrome gives me "uncaught syntaxerror: unexpected token }" on line doesn't have closing curly brace. here portion of script has error: function showm(id1){ window.onscroll=function(){document.getelementbyid(id1).style.top=document.body.scrolltop;}; document.getelementbyid(id1).style.display="block"; document.getelementbyid(id1).style.top=document.body.scrolltop; } does have ideas on this? appreciated. try running entire script through jslint . may point @ cause of error. edit ok, it's not quite syntax of script that's problem. @ least not in way jslint can detect. having played live code @ http://ft2.hostei.com/ft.v1/ , looks there syntax errors in generated code script puts onclick attribute in dom. browsers don't job of reporting errors in javascript run via such things (what file , line number of piece of script in onclick attribute of dynamically inserted element?). why confusing

struct accountinfo { string username; string password; } now if want have nullable instance should write: nullable<accountinfo> myaccount = null; but want make struct nullable nature , can used (without use of nullable<t> ): accountinfo myaccount = null; you can't. struct considered value types, , definition can't null. easiest way make nullable make reference type. the answer need ask "why struct?" , unless can think of solid reason, don't, , make class. argument struct being "faster", overblown, structs aren't created on stack (you shouldn't rely on this), , speed "gained" varies on case case basis. see post eric lippert on class vs. struct debate , speed.

i have delphi 7 project in there record types containing strings loaded , stored files. after recompiling delphi 2009, when program loads records file, strings messed because compiler expects unicode while file has ansi strings. type similar this: type tpoint = record name: string[255]; x, y: integer; end; after substituting "string" "ansistring" project doesn't compile saying "e2029 ';' expected '[' found". suggestions? shortstring (which string[255] is) still interpreted same way before: an array of ansichar first byte length. ansistring can not defined array, therefore error message. how read file fill records? , how fill them? maybe error occurs there.

case 1: i load large html page includes lot of complex layout , fonts. page take unknown time render. case 2: i use jquery .html() function make significant changes dom. modified dom take unknown time render. in both cases, want able cover whole screen spinner until page has completely finished rendering . in searching answers question, have found similar questions asked answers not relevant. clear: i don't want know when dom ready. i don't want know when http data has been fetched. i want know when in dom has been completely drawn screen . setting worst-case timeout not acceptable solution. i need solution webkit based browsers. just small point; browsers won't animate spinner whilst they're processing javascript. particularly ies behave single-threaded. it's worth using different, non-animated, design 'spinner'. hourglass. thought when's rendered challenge: why not put after initialisation code call in $(docum

"upcrun -v" may illuminate problem, without resorting man page ;)

i have desktop application. users register use it. when register, need make sure email address unique. need send request website keeps list of email addresses , returns results. what simplest, quickest way asp.net? i this: send webrequest: http://www.site.com/validate.aspx?email=a@a.a and aspx returns xml: <response>valid</response> there few other simple tasks this. there no need heavy security or need make system particularly robust due high demand. i have used web services before seems overhead simple task. is there elegant api wraps communication system must common. http has covered. check response code server. http://en.wikipedia.org/wiki/list_of_http_status_codes i suggest use 409 conflict indicates request not processed because of conflict in request but http 418 favorite since opengl.

my code lot of input/output , involves creation of temporary arrays hold bytes or chars of size - use 4096. im starting wonder - without actual tests - verify if better pool these arrays. code change this take array pool try { read 1 inputstream write outputstream using array } { return array pool } it quicker take or create byte 4096 means work required alloc mem on heap, clear 4096 bytes etc. a pool seems simpler after checking list taking list , returning array. update wrote small program did 2 things, created arrays , used apache commons pool. both looped lot of times (100*100*100) , created/took, filled array, released. added few goes in beginning warm jit , ignored results of those. each run ran create , pool forms dozen times, alternating between two. there little difference between pool , create forms. if added clear array callback fired apache commons pool when instance returned pool, pool became slower thanthe created form. i not implement poo

i'm creating backup script our database servers, , thought i'd ask if there preferred options include mysqldump . script called cron every 6-24 hours. we use innodb exclusively. our databases rather large, , i'll dump clusters of tables individually, opposed entire database in 1 go. for now, i'm thinking of including: --opt # enabled default --quote-names # enabled default --single-transaction --skip-comments any other suggestions or pointers creating good, reliable dump files? i propose set 1 more server (slave) mysql , replicate data there (from main, master one). if you'll need plain text dump - can slave without hurting master.

i have eclipse plugin project uses swt objects, eg - import org.eclipse.swt.widgets.composite; when try compile 'target platform' set 'running platform (active)', compiles fine , dont need import swt specific plugins. however, created target platform eclipse 3.6.0 , if set active platform project has compile errors wherever swt classes used , cannot resolve them. which plugin should add dependency to, resolve these errors? i tried adding 'org.eclipse.swt' not seem help. i had same problem. in case, had missing dependency , asked eclipse locate plugin me. after plugin found on p2 site, saw "resetting target platform" in progress view. after that, lot of plugins broken. checking target platform (window -> preferences -> plug-in development -> target platform -> edit), field "architecture" had changed x86_64 x86 . changing value , clicking on "finish" did reset tp once more , errors went away.

i have spot following pattern in code i'm working with: in classes in destructor have found private variable being nulled, in example: public function __destruct() { foreach($this->observers $observer) { $observer = null; } $this->db_build = null; } is there point in doing when php has gc? somehow improve performance of script? it could because php's garbage collection based on reference countring , , older versions not handle cyclical dependencies. then, in cases have been necessary manually set references null enable gc work, , there may still special cases cycle detection algorithm not catch. more though, it's example of cargo cult programming (the wikipedia entry explicitly lists example).

i working on code translation project sample antlr tree grammar as: start: ^(program declaration+) -> program_decl_tmpl(); declaration: class_decl | interface_decl; class_decl: ^(class ^(id class_identifier)) -> class_decl_tmpl(cid={$class_identifier.text}); the group template file looks like: group my; program_decl_tmpl() ::= << *what?* >> class_decl_tmpl(cid) ::= << public class <cid> {} >> based on this, have these questions: everything works fine apart should express in what? program list of class declarations final generated output? is approach averagely suitable not high-level language? i have studied antlr code translation string templates , seems approach takes advantage of interleaving code in tree grammar. possible as possible just in string templates? solution , add solution based on terence proposed: start: ^(program d+=declaration+) -> pr

i wondering why casts in c# checked @ compile-time whereas in other cases responsibility dumped on clr. above both incorrect handled in different way. class base { } class derived : base { } class other { } static void main(string[] args) { derived d = (derived)new base(); //runtime invalidcastexception derived d = (derived)new other(); //compile-time cannot convert type... } while reading "c# in depth" i've found information on topic autor says: "if compiler spots it’s impossible cast work, it’ll trigger compilation error—and if it’s theoretically allowed incorrect @ execution time, clr throw exception." does 'theoretically' mean connected inheritance hierarchy (some affinity between objects ?) or compiler's internal business? upcasts can checked @ compile time - type system guarantees cast succeeds. downcasts cannot (in general) checked @ compile time, checked @ runtime. unrelated types cannot cast e

is possible bypass auth component , logged in administrator? want test plugin downloaded , requires logged in using auth component admin don't want setup users table etc. you can bypass authentication using following code in beforefilter() of controller: function beforefilter() { parent::beforefilter(); $this->auth->allow('*'); } if want toggle specific actions: function beforefilter() { parent::beforefilter(); $this->auth->allow('admin_index', 'admin_view'); } now, won't have log in access these pages. :)

i'm "transactionalizing" extensive database manipulation , came across issue if run sql queries through hibernate not using mql approach, view of database doesn't appear correct. code uses hibernate in more appropriate manner in cases there places decided execute sql. don't did @ point "it is". i found explanation seems explain examples wrt getting , managing transaction in code. using @transactionattribute annotation on entire class change code , finding lot of places behavior happens i'm not entirely convinced explanation applies code wrapped in annotation--i assuming using hibernate manager rely on object cache in session. apologies in advance if referring concepts in hibernate incorrect terminology, etc. your question confusing, assume saying hibernate not looking entities in session cache when performing native queries. sql query, or native query, query hibernate relays database. hibernate won't parse query, , won't p

forgive ignorance these 2 technologies, learned of them morning. read them , use, not ruby developer. is there non-ruby equivalent sass and/or haml ? or maybe i'm asking wrong question entirely, use these in c# project. since large part of haml lies in allowing focus on actual code in templates , less on markup, it's tied specific language. fortunately, there versions popular languages, including nhaml .net . sass language of own , output independent of ruby — need ruby run compiler.

i'm developing c# application , need start external console program perform tasks (extract files). need redirect output of console program. code this one not work, because raises events when new line writen in console program, 1 use "updates" what's shown in console window, without writting new lines. how can raise event every time text in console updated? or output of console program every x seconds? in advance! i have had similar (possibly exact) problem describe: i needed console updates delivered me asynchronously. i needed updates detected regardless of whether newline input. what ended doing goes this: start "endless" loop of calling standardoutput.basestream.beginread . in callback beginread , check if return value of endread 0 ; means console process has closed output stream (i.e. never write standard output again). since beginread forces use constant-length buffer, check if return value of endread equal buffer size. mea

to win32 professionals. let's have completed existing application window. task write application (my) window. window must align left edge existing window right edge while user moves existing window across screen (my window not allowed move user). precondition: a) existing window can not subclassed b) windows hooks not case. yes, looks right. i'd not asked question if not become problem. forgot os vista 2, application ie. try make application follows ie main window, align edge. subclassing of ie not allowed, , setwindowshook not works correctly under regular user (when user have admin privileges application works normally). such way of talking works under windows prior vista. and looks there no trivial way solve task. thank all. i think can't without hook. setwindowlong allows set wndproc, won't work if window belongs different application.
