is using ( condition or condition b , condition c ) the same as ( condition , condition c) or (condition b , condition c) no. first condition is: (condition a) or (condition b , condition c) and second is: (condition , condition c) or (condition b , condition c) you can see difference between them.

i'd opinions if plan worthwhile or not. have existing site, , elements have css class defined. thought append each element has class new class: <div class="existingclass"> would turn into: <div class="existingclass newclass"> then, if want override attributes in "existingclass", in "newclass" (because last class attributes taken?). figure way, nothing break, not risk because not removing "existingclass". any problems plan? first know in existingclass . write newclass in such manner won't break layout. knowing in existingclass use tools firebug save time.

i using tfs's team explorer manage visual studio projects. recently, i've created new java project (not in visual studio) manually added tfs using source control control explorer in visual studio. after added java project tfs, made changes , bug fixes. then, went visual studio , opened source control explorer check in changes, tfs thinks no changes made. it seems needed check out project before making changes. guess erroneously expected tfs track automatically, okay. so, using source control explorer in tfs, checked out project, , tried check in pending changes. when tried check in, got following message: all of changes either unmodified files or locks. changes have been undone server. is there way convince server indeed project has changed? how can check in changes have made? thank help.

i looking way create bell curve in php. have tried jpgraph, , lined scatter graph, have no idea how align bell curve. honestly i've never used bell curve , i've got make 1 takes 3 inputs charity organization, have no idea how work, appreciated. i have quite understanding of php , if possibly paste code, find way understand it. simple bell curve for ($x = -m_pi; $x <= m_pi; $x += (m_pi / 20)) { echo sprintf('%+01.2f => %01.8f' . php_eol, $x, (cos($x) + 1) / 2); } but please explain 3 inputs: expected gaussian curve, mean, standard deviation , x value. bell curve special case of gaussian mean of 0 , standard deviation of 1, x value variable.

so i've got following rewrite code in htaccess rewriteengine on rewritecond %{http_host} ^[^.]+\.[^.]+$ rewriterule ^(.*)$ http://www.%{http_host}/$1 [l,r=301] // rewriteengine on rewritecond %{http_host} ^www\.([^\.]*)\.domain\.com$ [nc] rewriterule (.*) http://%1.domain.com$1 [r=301,l] works perfect redirecting non-www www domains. i've got subdomain, lets call ' sub.domain.com ' works find. if goto www.sub.domain.com , redirecting ' sub.domain.com/sub/ ' having idea why? none of rules have in question routes requests subdomain's folder. /sub/ should never there if wasn't in request. that said, of redirect rules need come before routing rules. routing rules being stuff internally routes requests other uri's, example: rewritecond %{http_host} ([^\.]*)\.domain\.com$ [nc] rewriterule (.*) /%1/$1 [l] that rule internall routes folder named same thing subdomain. if rule before redirect, both rules applied , redirected uri be...

i have string. need know if of following substrings appear in string. so, if have: thing_name = "visa assessments" i've been doing searches with: any((_ in thing_name _ in ['assessments','kilobyte','international'])) i'm going through long list of thing_name items, , don't need filter, exactly, check number of substrings. is best way this? feels wrong, can't think of more efficient way pull off. you can try re.search see if faster. along lines of import re pattern = re.compile('|'.join(['assessments','kilobyte','international'])) ismatch = (pattern.search(thing_name) != none)

examining code, don't see why fails. primary controller's index method looks this: public actionresult index(int appeventid = -1) there isn't querystring param, there's need route main page , pass particular id auto-display. default value of -1 indicates should display normally. works fine normally. in page, razor code generates valid hyperlink: @html.actionlink("back main", "index", "maincontroller", new { appeventid = -9 }, new { }) // things renamed protect innocent! when testing locally works charm. controller index method detects -9 particular value , specific case. however, when deployed on web server, application in subfolder, not root. works fine, in above case, generates url this: http://server/appsubfolder/?appeventid=-9 and above url looks correct, controller's index method not passed -9. is there limitation mvc app cannot deployed subfolder? i'm not 1 decided deploy way, i'm trying make sens...

i'm sure there has quicker way following. wasn't able find how save laravel modal object new row without overwriting existing item. essentially, simpler of existing code: $olditem = item::find(1); $newitem = new item; $newitem->key = $olditem ->key; $newitem->name = $olditem ->name; $newitem->path = $olditem ->path; $newitem->save(); instead, copying id of row: $olditem = item::find(1); $newitem = $olditem; unset($newitem->id); $newitem->save(); you can try $newitem = item::find(1)->replicate()->save();

say, if have byte array of various length , pass-phrase, quickest way encrypt in platform-independent way? ps. can make sha1 digest on pass-phrase how apply byte array -- doing simple repeated xor makes obvious. ps2. sorry, crypto guys, if i"m asking obvious stuff... a hash (like sha1) create one-way result, cannot decrypt hash. xoring data not secure means, don't that. if need able decrypt data, suggest using twofish uses symmetric key block cipher , not restricted licensing or patents (thus can find platform independent reference code).
