i have website (guidemanche.com) loads static maps images directly googlemaps. works fine if connected internet. if disconnected, or in case of site copy on cd, no more image. so, dl image created, store on server , display in page jpg file. doesn't work , have black image. my code is: <?php $url="http://maps.google.com/maps/api/staticmap?center=[(#latitude|scannav)],[(#longitude|scannav)]&zoom=14&size=450x400&maptype=hybrid&format=jpg&markers=color:blue|label:w|[(#latitude|scannav)],[(#longitude|scannav)]&sensor=false"; $filename="googleimg/#id_article.jpg"; if (!$handle = fopen($url, 'r')) { echo "impossible d'ouvrir le fichier ($filename)"; exit; } $contents = stream_get_contents($handle); fclose($handle); $handle2=fopen($filename, 'w'); // ecrivons quelque chose dans notre fichier. if (fwrite($handle2, $contents) == false) { echo "impossible d'écrire dans le fichier ($filename)&qu

i taking input camera. more clear added photo: 2 cameras connected on same usb port with opencv following : #define camleft 2 #define camright 0 #define win_l "win_l" #define win_r "win_r" int main(int argc, const char * argv[]) { videocapture capleft(camleft); bool opened = capleft.isopened(); if(!opened /*|| !capright.isopened()*/) // check if succeeded return -1; mat edges; namedwindow(win_l,1); for(;;) { mat framel; mat framer; capleft >> framel; // new frame camera cvtcolor(framel, edges, cv_rgb2rgba); imshow(win_l, edges); if(waitkey(30) >= 0) break; } return 0; } so creating window named "win_l" stands window left , process video capture. works well. upgraded code support camera this: int main(int argc, const char * argv[]) { videocapture capleft(camleft); videocapture capright(camright); bool opened = capleft.isopened(); if(!opened

so know git submodules , subtrees. used able have nested full git repositories treated nothing simple filesystem subdirectories? for example, given: topdir/ file1 file2 subdir1/ file1 file2 subdir2/ file1 file2 subdir3/ .git/ file1 file2 previously, executing: $ git init && git commit -a . in topdir result in files of subdir3 being committed raw or literal subdirectory (i.e. not submodule), '.git' directory in subdirectory ignored in super- or top-level repository. entering subdir3 make subdir3/.git current repository. with 1.8.2.1.501, there not seem way behavior back. running above command results in subdir3 being considered submodule but, perversely not added index. have explicitly git submodule add add files under main repo. when did change happen? is there way old behavior back, i.e., have subdirectory treated regular directory, , not git submodule or subtree?

i trying find string within string. however, trying match if 1 or more character not matching. let me explain example : let's have string 'abcdefghij' . if string match 'abcd' , i write strfind('abcdefghij', 'abc') now, have string 'adcf'. notice that, there mismatch in 2 characters, consider match. any idea how ? i know, not optimal code. example : a='abcdefghijk'; b='xbcx' c='abxx' d='axxd' e='abcx' f='xabc' g='axcd' h='abxd' ='abcd' all these strings should match a . hope example makes more clear. idea is, if there mismatch of 1 or 2 characters also, should considered match. you this: a = 'abcdefghij'; % main string b = 'adcf'; % string found tolerance = 2; % maximum number of different characters tolerate na = numel(a); nb = numel(b); pos = find(sum(a(mod(cumsum([(1:na)' ones(na, nb - 1)], 2) - 1, na) + 1) == repm
