a third party providing me edt time-stamp in following format: mm/dd/yyyy hh:mm for instance: '08/19/2013 11:31' i need convert pst javascript (same date time format) , have been looking on can't find info doing this.. if can me example code appreciate it. if wanted manually, can try following: split space, have date , time. split time ":" , split date "/". create new date() , provide right values in right order. subtract 3 hours using proper methods, recreate format. here's example of this: var est = "01/01/2014 02:31", finaldate, pst; finaldate = parsedatestring(est); finaldate.sethours(finaldate.gethours() - 3); pst = formatdate(finaldate); console.log(pst); function parsedatestring(str) { var datetime, date, time, datesplit, month, day, year, timesplit, hour, minute; datetime = est.split(" "); date = datetime[0]; time = datetime[1]; datesplit = date.split("/"

i working in netbeans 7 python script using jython. trying build nasa worldwind example. i have added jars classpath, including 1 contains gov.nasa.worldwind. the code crashes, saying traceback (most recent call last): file "c:\users\wrightky\documents\netbeansprojects\ww\src\ww.py", line 4, in <module> import gov.nasa.worldwind wwj importerror: no module named gov i have both added jar "gov" classpath , added jar python package manually, under can see gov.nasa.worldwind. i add code not sure if it's relevant. why happen? from question it's not entirely clear whether you're compiling java class file or python, if java should know can't import x y in java. if have conflicting class names, you'll have use fully-qualified class name (ie gov.nasa.wordwind.someclass ) every time reference it. see question more details: change name of import in java, or import 2 classes same name

in django rest framework, involved in creating flat, read-write serializer representation? docs refer 'flat representation' (end of section http://django-rest-framework.org/api-guide/serializers.html#dealing-with-nested-objects ) don't offer examples or beyond suggestion use relatedfield subclass. for instance, how provide flat representation of user , userprofile relationship, below? # model class userprofile(models.model): user = models.onetoonefield(user) favourite_number = models.integerfield() # serializer class userprofileserializer(serializers.modelserializer): email = serialisers.emailfield(source='user.email') class meta: model = userprofile fields = ['id', 'favourite_number', 'email',] the above userprofileserializer doesn't allow writing email field, hope expresses intention sufficiently well. so, how should 'flat' read-write serializer constructed allow writable email at

i encountered problem , didn't find solution this. i'm pretty confused because thought simple requirement. there following elements: a surrounding div#wrapper div#a, floating left , fixed width div#b, floating left (right of #a) , dynamic width inside of div#b there plenty of images, floating left , fixed width (and height). depending on screen resolution there should 1, 2, 3, n columns of images on right part of screen (next div#a). instead of this, container #b aligned below container #a , uses full window width. my alternative attempt giving #b float:right , margin-left (which greater width of #a), didn't work. i avoid absolute positioning because height of surrounding wrapper should increase content. to visualize i'm talking about, made following diagram: http://abload.de/img/rezeptbilder1k8lsr.png many in advance! this happening because..you having dynamic width div#b ...ans there plenty of images , aligned next each other...so div#b

here code: sessionstorage.loggedin = true; if (sessionstorage.loggedin) { alert('true'); } else { alert('false'); } simple enough. there must small thing i'm not understanding how javascript evaluating these expressions. when put sessionstorage.loggedin = false , "false" alert shows correctly. however, when change sessionstorage.loggedin true, "false" alert still pops, after clearing session. not getting right expression? seems simple, maybe need pair of eyes on it. try change code to sessionstorage.setitem('loggedin',json.stringify(true)); if (json.parse(sessionstorage.getitem('loggedin'))) { alert('true'); } else { alert('false'); } and should work consistently across major browsers. the interface setitem / getitem methods how spec written, going way safer using shortcut of assigning properties. also, sessionstorage , localstorage textbased s

i asked: replace each number in list sum of remaining elements, list not sorted. suppose if have list of numbers {2, 7, 1, 3, 8} , replace each element sum of rest of elements. output should be: {(7 + 1 + 3 + 8), (2 + 1 + 3 + 8), (2 + 7 + 3 + 8), (2 + 7 + 1 + 8), (2 + 7 + 1 + 3)} == {19, 14, 20, 18, 13} i answered obvious solution: first evaluate sum of numbers subtract each element sum . above list sum 2 + 7 + 1 + 3 + 8 = 21 , output like: {sum - 2, sum - 7, sum - 1, sum - 3, sum - 8} {21 - 2, 21 - 7, 21 - 1, 21 - 3, 21 - 8} == {19, 14, 20, 18, 13} it needs 2 iterations of list. then interviewer asked me: without subtraction? , couldn't answer :( is other solution possible? can share other trick? better trick possible? lets memory space can used (i asked after few minutes of try, couldn't answer). one possibility compute prefix , suffix sums of array , combine appropriate entries. still o(n) needs more memory space thi

so have class hierarchy has entity class parent abstract class , bunch of other classes derive it, such door , player , ground , etc. i have three-dimensional vector stores pointers objects of type entity , fill vector derived objects. within door class have method called isopen() returns bool . function specific door class , neither found in entity class nor in other derivations of (as don't need check whether, example, ground object open or not). now, knowing there exists object of type door @ vector position i , j , k , call method isopen so: vector[i][j][k]->isopen() . unfortunately, when this, compiler returns class entity has no member named isopen() . understandable since function isopen() exclusive door class, can in order make sort of call possible? one way solve down cast door * first. however, in order down cast type safe, should use dynamic_cast<door *>() . if entity not have virtual method, can add virtual destructor. class

i have java project initializes thousands of objects in tree-like hierarchy. initially, programming performance in mind , didn't mind storing lot of computable properties in class fields(variables).. however, recently, started trying estimate memory footprint of project , found large. i'm trying identify class consumes memory guess can narrow down field consuming (probably strings) i have come across java's instrumentation package , getobjectsize i tried understanding documentation, i'm not sure if instrumentation suited task. have noticed getobjectsize not recursively find sizes. i thinking of creating class extends object , contains static map of instance -> instancesize , , making classes extend class , updating constructors is approach correct? 'java' way of accomplishing this? um, put down coding tools , pick memory profiler. there great free ones out there.

i wonder if there can such thing. wanna check size of file , htaccess rules based on it. example: # line checkif {requested_file_size} 50 # mb authname "login title" authtype basic authuserfile /path/to/.htpasswd require valid-user it's clear want make files specific file size available users (using authentication) any idea appreciated. update #1 should done in htaccess update #2 there many files , urls posted in blog. can't separate larger files folder , update each post, limitation of file size may change in future. update #3 it's windows server php & helicon app installed update #4 some people got confused real issue , didn't clear either. .htaccess + php file authentication (uses api) , checking file size + downloadable files in same server but our website hosted on different server. obviously .htaccess cannot check requested file size , act accordingly. can possibly make use of external rewriting program feature
