(if programmed shouldn't necessary either.) if enter method , not sure object in valid state, being in invalid 1 not "unexpected" behavior, , should handled differently. this check method come place. shouldn't throw exception should return boolean, determine next. invalid object in case reasonable, use code handle case check method returns valid...

the node-binary binary parser builds object following pattern: exports.parse = function parse (buffer) { var self = {...} self.tap = function (cb) {...}; self.into = function (key, cb) {...}; ... return self; }; how inherit own, enlightened parser this? pattern designed intentionally make inheritance awkward? my successful attempt far @ inheriting methods of binary.parse(<something>) use _.extend as: var clever_parser = function(buffer) { if (this instanceof clever_parser) { this.parser = binary.parse(buffer); // guess super.constructor(...) _.extend(this.parser, this); // really? return this.parser; } else { return new clever_parser(buffer); } } this has failed smell test, , of others. there makes in tangerous? how about: var clever_parser = function ( buffer ) { var parser = binary.parse( buffer ); _.extend( parser, clever_parser.methods ); return parser; } clever_...

efficiency of map::insert(iterator position, const value& k) can dramatically improved providing appropriate value in parameter position. if use integer numbers key, , every insertion done number larger inserted keys, can speed ::insert operation when giving ::end() iterator of map? something like: mymap.insert( mymap.end() , make_pair( next_number , myvalue ) ); where mymap of type map<uint64_t,mytype> , next_number every incrementing large integer. edit: the answer question might differ depending on whether data stored in map dense or not (see discussion below). so, lets ask question in both ways: once it's dense once it's not. still curious. perhaps measuring answer it. to directly answer question asked, c++ specs that: in c++03, insertion map a.insert(p,t) must amortized constant complexity (rather logarithmic) if t inserted right after p . in c++11, insertion map a.insert(p,t) must amortized constant complexity if t insert...

let's have 200 pixels of space , want draw 2 strings it: - first string should left justified - right second string should right justified - not overlap if not both fit (then whatever string.trimming options say) am going have measure each , draw manually, or drawstring have way support i'm trying without me reinventing wheel? imagine \l , \r escapes did this, say graphics.drawstring("\lfirst\rsecond", ...); and i'd wind like "first second" at least that's i'd have happen (i know \l , \r not exist). there way? i've ignored flags , instead i'm showing (roughly) how can align text. it's easy enough pick out text, split , draw 2 separate strings! string text2 = "use textformatflags , rectangle objects to" + " align text in rectangle."; using (font font2 = new font("arial", 12, fontstyle.bold, graphicsunit.point)) { rectangle rect2 = new rectangle(150, 10,...

say have multithreaded application , run same inputs . enough instrument every load , stores detect write-write , write-read data races? mean logged load , store addresses, if can see thread did load , thread did store, can detect write-read , write-write data race noticing overlapped addresses. or missing something? or missing something? you are missing lot. pubby said, if see read, write in t1, , later read, write in t2, can't anything absence of races. need know locks involved. you may want use tool, such google's threadsanitizer instead. update: but approach cover races or @ least of races? your comments here , on other answers appear show don't understand race is. your approach may expose some of races, yes. guaranteed not cover of them (which make exercise futile).

i have handful of files wish not commit svn duration of 1 commit while having rest commit repository. there svn command can in sense ignore specified files commit want make? well link pointed out in comments helpful point, ended having commit files/folders specifically, working around ones didn't want commit through svn ci -m 'message' folder/file might not have been elegant method, worked, , has taught me valuable lesson in making sure commit per moving piece/section before moving on next.

my problem not coding general design question. wrote chrome extension connects user through socks5 proxy (via ssh) vpn network. if proxy process killed or connection interupted socks proxy reconnect , on successful connection (failed) tabs reloaded. while connecting network browseraction icon animated. works fine far. what want decent visible hint, there going on in background , user has wait few seconds until clicks link or opens tab. thought alerts, hates them , of course right. thought animated message twitter or growl, injecting page content script not seem work on error pages. showing messages @ browseraction text or showing popup doesn't seem possible. my question is: of know extension solved nicely or have idea how solve this. should visible @ first sight without being anoying. ideas welcome! you can animate browser action or page action icon. see example: http://code.google.com/chrome/extensions/samples.html#9a6e4ec46997fb92b324974afa08a3d007e2537f

i have absolutely strangest bug i've ever encountered, , i'm near wit's end on one. ideas on how debug (or clever workarounds) awesome. the problem: i'm making simple wysiwyg editor in firefox using contenteditable. problem appears when load text edit via ajax. before load, cursor appears fine (for split second), , once text loads disappears. can still enter text, , cursor still "there" (a status box shows current line/col fine), cursor not visible , selection overlay not appear. here's makes strange: clicking anywhere, on other dom element, on firebug, on window -- makes cursor return , behave normal. in fact, time cursor has problems @ beginning, when loading page or on refresh. clicking anywhere inside contentedtiable div not fix -- have click outside refresh. right now, need workaround. i've tried 500 flavors of $(someelement).click or $(somelement).focus, don't replicate "actual" click user. has seen before? ...

is there way construct matrix in octave's c++ api pointer data + size (ie, not using deep copy)? possibly undocumented unsafe way, caller has manage corresponding memory, or way assign pointer data? thing find method in dmatrix.h, private: matrix (double *d, octave_idx_type r, octave_idx_type c); same array.h, pointer data seems private.

i have table in mysql manage using phpmyadmin. it's sitting @ around 960,000 rows. i have boss likes @ data in excel, means weekly, have export data excel. i looking more efficient way this. since can't entire table @ once, because times out. have been stuck 'chunking' table smaller queries , exporting that. i have tried connecting excel (and access) directly database, same problem; times out. there way extend connection limit? honestly size of data, suggest doing mysqldump importing table copy of mysql installed somewhere else, maybe on virtual machine dedicated task. there, can set timeouts , such high want , not worry resource limitations blowing production database. using nice on unix-based oses or process priorities on windows-based system, should able without impact production system. alternatively, can set replica of production database , pull data there. having so-called "reporting database" replicates various tables...

i need draw arbitrary string directly on screen (not inside rich text control) using mfc and/or windows api. characters within string can vary in font face or color, , can bold, italic, underlined, or combination of two. additionally, users can choose wrap text within bounds of choosing, option force fit adjusting font size. i'm thinking of doing along lines of: parsing vector of substrings , formats using getcharabcwidthsfloat calculate widths of substrings manually calculating line breaks need fall repeating above iteratively smaller fonts if necessary make text fit drawing each of substrings individually drawtextw, determining locations using widths of preceding substrings , line break points is there better approach? if not, there gotchas or tricks should aware of when implementing this? (i'm aware of dt_calcrect | dt_wordbreak flags drawtext, don't think that'll work me because a) assumes consistent font/formatting across whole string , b) saw message b...

for xperia play prior ics, way input touchpad through nativeactivity (not plain old activity). unfortunately, drawing in nativeactivity, name suggests, done on native-side, not java-side. in order input on native-side graphics on java-side, following must added nativeactivity's oncreate method: getwindow().takesurface( null ); getwindow().setcontentview( r.layout.main ); and set couple methods through jni receiving touchpad , touchscreen input native-side. can happily draw through android's java api, while still getting touchpad input. works quite xperia play's running pre-ics. adding menus via oncreateoptionsmenu doesn't cause problem. the problem comes when xperia play running ics. menu has moved action bar. unfortunately, isn't possible interact action bar (pressing 3 dots ignored, , acts i'm pressing surface behind action bar.) in case makes difference, creating action bar menu options through oncreateoptionsmenu. using window.fea...
