javascript - References for Ad Blocker like web content filtering -

i want implement extension browsers blocks 3rd party pop ads, on lines of advertisement blocker. don't know start. can point me towards references can utilize larn more filtering web content? in advance.

i hate shove links have found need on here:

http://developer.chrome.com/extensions/index.html

if take time read you'll understand how extension built , lives in browser. if read long plenty you'll find section:

http://developer.chrome.com/extensions/content_scripts.html

which details how can inject javascript tab , run context of page vs. context of plugin.

the resources detailed, have read them.

to follow comment, no. every browser environment architected differently , you'll have take different approach same problem, if goal same.

the way see it, there's 2 ways of doing (at high level). stop transmission happening, or retroactively remove elements page after it's loaded.

if stop transmission, it's improve because should prevent lot of drive-by exploits bytes never create computer, or @ to the lowest degree page.

as duskwuff explained, chrome has api lets intercept requests , create decision @ time. ie going have totally different api chrome, , firefox different both.

taking retro-active approach perchance build javascript that's x-platform runs against page , removes ads. work "cross-browser" if can find unique method injecting/executing script in tab on browsers, implementation of portion unique platform.

different browsers utilize different languages.

chrome uses js/html5 extensions, can utilize native dlls apparantly you're treated higher scrutiny when submit extension store because binary needs vetted wont expose problems browser because html/js versions live within sandbox , can isolated.

firefox has changed quite bit in lastly while, haven't kept date thier changes, it's totally different ballgame. thier extension framework @ 1 point had been matured plenty build little standalone apps iirc, may wrong.

ie com extensions, may have changed bit in lastly while you'll making .net or c++ .dlls interop com interface browser.

so can see it's different each browser, there's outliers (safari / opera / etc...)

let's not forget lot of these browsers cross-platform , depending on how attack problem may have take account.

it's worth noting: chrome asynchronous model, each tab / plugin lives "isolated" each other, , communicate using asynchronous messaging basically. makes general approach working browser fundamentally different other browsers because need work within callback methods lot.

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
