is there way, using library or method, scrape webpage in real time user navigates manually? scrapers know of such python mechanize create browser object emulates browser - of course not looking since if have browser open, different 1 mechanize creates. if there no solution, problem want scrape elements html5 game make intelligent agent of sorts. won't go more detail, suspect if others trying same in future (or real time scraping real user), solution useful them well. thanks in advance! depending on use-case is, set socks proxy or other form of proxy , configure log traffic, instruct browser use it. you'd scrape log somehow. similarly, if have control on router, configure capture , logging there, e.g. using tcpdump . wouldn't decrypt encrypted traffic, of course. if working 1 browser, there may way instruct @ each action via custom browser plugin, i'd have guess you'd running security model issues lot. the problem html5 game typically of &q

i've got basic readline implementation seems have problem when write written data appears in input , raises 'line' event. in standard linux rxvt window. var rl readline.createinterface({ input: process.stdin, output: process.stdout, // terminal: false <--- setting true/false makes no difference }); rl.on('line', function(line) { var inp = line.trim(); console.log('line event'); switch(inp) { case .... default: console.log('unknown command: ' + inp + '\n'); } }); and rl.write(string); from socket i/o. write raises 'line' event , written data apears unknown command. if enter data on terminal raises 'line' event expected , works ok. clearly data written shouldn't appear on input , asking might reason this. thanks actually rl.write trigger line event. should in docs isn't. if want bypass parser write process.stdout. previously termina

just wondering if developers use xcode develop in same way. in, developers or angry birds make view controllers? there 1 way go developing apps in xcode, , major companies way? also, how go developing ios app in c or c++ , not objective-c? need use objective-c? how can develop using c or c++? angry birds , such created game engines such corona ( http://www.coronalabs.com/products/corona-sdk/ ) note rovio (angry birds) developed own game engine. if you're interested in developing games suggest game engine rather doing code via xcode (while might possible :)).

my question layout in image: white box in upper right corner = content box the black line @ bottom = footer bar the box right = sidebar box the sidebar set css position: fixed , follow users scroll. the problem is, on small screen sizes, user can scroll far, meaning sidebar box, go futher down footer bar. how can make sidebar stop 20 pixels before hitting footer? css code: div#sidebar { margin: 20px 0px 20px 20px; width: 270px; height: 295px; border: 1px solid #ccc; background-color:#fff; padding: 20px; position:fixed; left: 730px; } div#content { margin: 20px 0px 20px 0px; width: 650px; height: 600px; border: 1px solid #ccc; background-color:#fff; float: left; padding: 20px; } div#footer { width: 100%; min-width:1024px; height: 30px; border: 1px solid black; background:#252525; text-align:center; padding-top:10px; color:#555; } i try adjust #sidebar margin-bottom . what's html?

i'm starting play little bit assembly excuse me if questions dumb. my questions (i'm trying divide 100 5, playing memory , variables of course!) why dw (define word) instruction executed that? mean, understand of others line in particular dark 1 me.. also, can explain me why var instantiated @ address 0010ah ? think it's because 4 istructions before instantiation occupy 4*16bits=4*2bytes=8bytes, , var filed on stack right after. shouldn't instruction elsewhere? loaded on stack once program starts run? bonus question: how can check what's on stack in emu8086? because using assembler , not compiler. literally translating mnemonics , data flat binary file (or more commonly, headers included ie pe). dw quite literally "declaring word". it's placing $0200 @ place in code. if look @ handy table , can see opcode add r8, r/m8 while i'm not going go whole opcode structure , disassembly, you'll see [r] meaning has modrm by
