i need download bmp javascript , render screen, in internet explorer. first off, yes, know insane, i'm not going why, let's accept moment img src not working because of security constraints, ajax request proper authentication in post pull image. example bypasses security sake of simplicity , proves can render something. the best idea come fetch stream via ajax, decode bitmap, , render canvas. internet explorer doesn't support canvas, luckily google provided wrapper svg called excanvas can use that. my code (drawing code appears work, bmp decoding not much) http://gist.github.com/614328 future support other images besides bmp plausable, , because of how canvas works it's easiest draw pixels in rgba. texture2d wrapper class rgba byte array, plus drawing code. bytestream makes bit easier on eyes dealing byte array, , bitmapdecoder contains method translate bgr format rgba texture2d drawing. is possible bytes getting mis-translated along way or there matt...

i stumbled across wikipedia page them: fusion tree and read class notes pdfs linked @ bottom, gets hand-wavy data structure , goes lot of detail sketch(x) function. think part of confusion papers trying general, , specific example visualize. is data structure appropriate storing data based on arbitrary 32 or 64 bit integer keys? how differ b-tree? there 1 section says it's b-tree branching factor b = (lg n)^(1/5) . populated tree 32 bit keys, b 2. become binary tree? data structure intended use longer bit-strings keys? my googling didn't turn terribly useful, welcome links on topic. passing curiosity, haven't been willing pay pdfs @ portal.acm.org yet. i've read (just quick pass) seminal paper , seems interesting. answers of questions in first page. you may download paper here hth!

i have cross-platform c++ project. in project, use several third-party, statically-compiled libraries quite huge , not easy build. currently, our source tree looks this: | +-3rdparty | +-include (initially empty) | +-lib (initially empty) | +-some-library | +-another-library | +-source when checking out code, developer first build , install "some-library" , "another-library". install step put right files include , lib folders, , can build our project. in order make building our project easier, thinking of removing "some-library" , "another-library", , instead put includes , pre-compiled binaries include , lib folders. way, new developper have checkout project, , build straight away. my questions are: is bad practice so? (ie: including precompiled libraries source tree). what potential problems / drawbacks may arise setup? what folder organization suggest account several platforms (windows, mac osx, , linux)? addition...
