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 trying create pre handler sanitizes data before written mongodb see: http://mongoosejs.com/docs/middleware.html i've tried following each property able sanitize it: blogschema.pre('save', function (next) { var obj = this; console.log(obj)//-> https://gist.github.com/daslicht/70e0501acd6c345df8c2 // i've tried following single items : object.keys(obj).foreach(function (key) { console.log('keys: ',obj[key]); }); //and: for(var key in obj) { console.log(obj[key]) } //and: _.each( self , function(value, key, list){ console.log('value:',key); }) next(); }) any of above approaches results following: thats output of: for(var key in obj) { console.log(obj[key]) } https://gist.github.com/daslicht/cb855f53d86062570a96 any know how each single property can sanitize it, please? ~marc [ed

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.

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).

i'm having unusual issue , doesn't seem related other posts i've found. i'm logging magento install have setup through mamp on local. doesn't "invalid password" or of nature, refreshes itself. i've tried modifying .htaccess , posting magento forum nothing. hit "submit" , seems refresh page. redirect issue? works fine on firefox reason chrome won't allow access. this because of how chrome handles cookies , can happen on production sites local installs. fastest fix log db (with phpmyadmin, mysql workbench, whatever), go table core_config_data , find column labeled "path" entry matches "web/cookie/cookie_httponly" - should closer end. you'll need set value column null. clear cache /var folder , should good. some sites tell modify varien.php - i've tried , can end log file can grow 2gb or more because commented out fields magento references every time pull data cookie. not good. let me know if work

i developing python script (here after script) searches through large log files search string. in normal use, called hudson front end. about hudson interface: hudson job creates temporary batch file on connected virtual machine (vm) calls script , passes parameters. have had hundreds of successful instances using setup, creating error. about script: log files contained in dozens of compressed .tgz files. script searches each log in each .tgz file. 1 of command line args script accepts true/false parameter called process_in_parallel . if process_in_parallel set true , each .tgz file searched in own thread (using multiprocessing module). if process_in_parallel set false , each .tgz file searched in sequence (using loop). what works: i have batch file on vm use testing script. can use .bat call script process_in_parallel set either (1a) true or (1b) false . of course, runs faster when true (about 4x faster). have quadruple-checked .bat passes same parameters
