the problem: how apache configuration simple python program run in kali linux through php script. i tried shows blank window. php script: <?php $co = escapeshellcmd('/root/desktop/python1.py'); $op = shell_exec($co); echo $op; ?> in var_dump shows null. me.. you want point shell program <?php $co = escapeshellcmd('/bin/sh /root/desktop/python1.py'); $op = shell_exec($co); echo $op; ?> or use python self $co = escapeshellcmd('/usr/bin/python /root/desktop/python1.py'); ps when know command, escapeshell redundant, can use shell_exec directly <?php $op = shell_exec('/bin/bash /root/desktop/python1.py'); echo $op; ?>

i extract json string within string. currently getting full string using file_get_contents , running following pattern on string: https://regex101.com/r/5jauco/1 pretty gives multiple matches. i extract json string saved in window._shareddata haven't been able achieve that. have idea how that? why not include _shareddata in regex like? _shareddata\s*=\s*\{.+\} or lookbehind: (?<=_shareddata\s=)\s*\{.+\} or take json capturing group: _shareddata\s*=\s*(\{.+\}) one concern lookbehind if add additional whitespace character between _shareddata , = won't match. this works since there no linebreaks in json.

ef 6.1.3. i have domain contains many instances of "header/ item" type pattern, header can have many items (1 many), , has "current" or "latest" item. this represented follows: header guid id guid currentitemid item currentitem icollection<item> allitems item headerid id the pk of items headerid + itemid. reason being that, far, common access pattern items list items related given header, , having headerid first part of pk/clustered index means data clustered index seeks. our problem when use currentitem navigation property, ever uses itemid lookup, results in not great query plans. i assume because conventions ef use currentitemid currentitem. question is, there way tell ef perform joins currentitem mapping header.id,header.currentitemid -> item.headerid,item.id? i believe slight different scenario 1 described here: composite key foreign key in case, have 1 one mapping not 1 top many, , there doesn

i've been working on days. so, project work protein data bank files (*.ent) using perl. have whole huge directory full of them, , need calculate distance between atoms cd1 , od2. if od2 not present, calculate distance between atom cd1 , oe2. never both atoms present in file. isn't issue me now, can directly print out values in each file within if , elsif condtional. but when exit if/elsif conditional, memory of values in each file, goes away. again, i've done lot of hard work open whole loop of files print solutions each file. essentially, in order calculate distance, need calculate radial distance 2 points: p(x1,y1,z1) , q(x2,y2,z2), point p x,y,z coordinates of cd1 atom, , point q x,y,z distance of od2 or oe2. called them alternatives cd1 atom coordinates. pq distance = sqrt[(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2] in order deal 800 (*.ent) files, used foreach loop iterative on files in directory, , while loop loop through them. there several columns of *.ent

i want fill 10000x2 matrix in opencv (v3.2) random numbers in uniform distribution different ranges each column , here problem following code: mat centers(10000, 2, cv_32f); rng rng(time(null)); rng.fill(centers, rng::uniform, scalar(0, 0), scalar(10, 1000)); i expect first column randomly filled values between 0 , 10 , second column filled values between 0 , 1000. both columns filled values between 0 , 10, decided implemented in following form. mat centers(10000, 2, cv_32f); rng rng(time(null)); rng.fill(centers.colrange(0, 1), rng::uniform, 0, 10); rng.fill(centers.colrange(1, 2), rng::uniform, 0, 1000); but not work either. think because rng::fill not support noncontinuous matrices (which not mentioned in documentation) remaining way use loop waste of time , performance. doing sth wrong above or should give , use loop you have misinterpreted api documentation of rng::fill() , defines parameters , b as: a - first distribution parameter; in case of uniform d
