using localstorage, try store users configs, , works well. // in options_page localstorage.setitem('mykey',someval); but it's difficult read configs content_scripts (´･ω･`) localstorage.getitem('mykey'); // because different 'window' scope i'm making using runtime.sendmessage // in content_scripts chrome.runtime.sendmessage(null, {purpose:'getconfig',configkey:'mykey'}, function(confhere){ // action } ); i think it's complex!! (and using 'chrome.storage' requires permission, ugly) there way read configs content_scripts of chrome extension? content scripts run within context of pages sharing dom , not extension. so, content script trying read localstorage read localstorage of page, , not extension. the way proposed correct , far know best way access setting info in content script. so, when content script created send message background settings (as have done) , in background add list

i have object. either long or string , simplify code let's assume that. i have create method tries convert object provided enum. so: public object toenum(type enumtype, object value) { if(enumtype.isenum) { if(enum.isdefined(enumtype, value)) { var val = enum.parse(enumtype, (string)value); return val; } } return null; } with strings works well. numbers causes problems, because default underlying type enum int , not long , isdefined throws argumentexception . of course can many checks, conversions or try-catches. what want have clean , small code that. ideas how make readable , simple? it feels me want handle 3 cases: input right type strings integers in various types i believe want valid input: public object toenum(type enumtype, object value) { if (value == null) { throw new argumentnullexception("value"); } if (enumtype == null) { throw

i building app in titanium studios, it's childrens sound app. going have 1 sound/animal per window. better split code(one(1) window per js-file) on different js files or should keep code in same app.js? also; first question on here bear me. all dependa how want design app, how code reused between windows , how complex it. in general it's split code between files wait until will.be big enouhh refactoring.

given string "this uppercase test url ( http://www.somedomain.com/some/path ). lowercase test url ( http://www.somedomain.com/some/path )" i have regex find urls: \(http://www.somedomain.com/(.*?)\) can amend return url if contains uppercase character in path? you can put positive lookahead check uppercase character: (?=\s*[a-z])\(http://www.somedomain.com/(.*?)\) ^^^^^^^^^^^^ it'll make sure there's @ least 1 uppercase character in string. regex101 demo if want make sure 'check' remains within brackets, can use this: \((?=[^)\s]*[a-z])http://www.somedomain.com/(.*?)\) regex101 demo

title says all. in short, how make wp_nav_menu(); output this: <nav> <a>menu item</a> <a class="current-menu-item">menu item</a> <a>menu item</a> <a>menu item</a> <a>menu item</a> </nav> i read http://css-tricks.com/snippets/wordpress/remove-li-elements-from-output-of-wp_nav_menu/ removes unordered list , list-items. but removing <li> s removes useful .current-menu-item class when you're on particular page. how class show on anchor tag instead? you can edit output via first parameter of function wp_nav_menu($args); . $args = array( 'theme_location' => '', 'menu' => '', 'container' => 'div', 'container_class' => '', 'container_id' => '', 'menu_class' => 'menu', 'menu_id'

can somehow invalid system.guid object created in .net (visual basic or c#). know guid.empty method not searching for. example invalid symbols or spaces or being short or longer valid 1 etc. thanks! can guid created invalid symbols or spaces or being short or longer valid 1 etc? no - guid 128-bit number can represented in 4 groups of hexadecimal numbers. there's no way string representation of guid contain other 32 hex characters (and 3 dashes). you can create string not represent valid guid , there's no way put guid object.

there's plenty of code , example floating around on how use lambda expressions raise inotifypropertychanged events refactoring freiendly code. typically used as: notifyofpropertychanged(() => propertyname); my question is, how achieve similar on receiving end of things, you'd typcially have switch statement of sorts: private void someobject_propertychanged(object sender, propertychangedeventargs args) { switch (args.propertyname) { case "xyz": break; //... } } now nice somehow avoid using strings here things not break when changing property name... as half-way solution use embedded class public constants such as: public class myclass { public static class notifications { public const string property1 = "property1" //... } //... } and on receiving end: private void someobject_propertychanged(object sender, propertychangedeventargs args) { switch (args.propertyna

while scikit learn documentation fantastic, couldn't find if there way specify custom error function optimize in classification problem. backing bit, i'm working on text classification problem false positives better false negatives. because labeling text important user, , false positives @ worst waste small amount of time user, whereas false negatives cause potentially important information never seen. therefore i'd scale false negative errors (or false positive errors down, whichever) during optimization. i understand each algorithm optimizes different error function, there isn't one-size-fits-all solution in terms of supplying custom error function. there way? example, scaling labels work algorithm treats labels real values, wouldn't work svm, example, because svm scales labels -1,+1 under hood anyway. some estimators take class_weight constructor argument. assuming classes ["neg", "pos"] , can give negative class arbitrarily

i trying session service working cloud endpoints when user refresh page, not lose everything. i thought had figure out gae-session : https://github.com/dound/gae-sessions works locally. but reason when upload code, session not work. not sure why happening (ssl maybe?) i session class myapi(remote.service): def __init__(self): # retrieve session if exists self.session = get_current_session() @endpoints.method(message, message, path='app_init', http_method='post', name='app.init') def appinit(self, request): if not self.session.is_active(): logging.info('session active') else: logging.info('no active session) any idea on doing wrong or maybe better solution? thanks

i have db (access 2010) pulling data from, trying make easier pull specific cases instead of mucking in excel. we have 78 product type codes classify account type. unfortunately can't use in() function because there many characters (there 1024 char limit). looked online , suggested make table inner join on product codes want. i created table codes want pull, joined on productcodetype in linked database table. unfortunately when run sql nothing shows up, blank. tried different join combinations no avail, read further , found can't enforce referential integrity on linked db tables non-linked db tables. i think problem i'm not sure, , don't know if i'm using right language, can't find similar issue mine i'm hoping it's easy fix , i'm not thinking right way. is there way select cases (78 product type codes) large database using in() or reference table when can't create new table in linked db? thank you, k you must use 2 tables

i beginner in java programming. have code below socket socket = serversocketobj.accept(); bufferedwriter writer = new bufferedwriter(new outputstreamwriter(socket.getoutputstream())); try { writer.writeline(); } catch(ioexception e ) { //write logger here } { writer.close(); // throws ioexceptioin too. // possible memmory leak? socket.close(); } when try close writer should handle exception. don't know it. exception impossible in case? can ignore it? if don't know them, catch them , log them. simplest way of logging them e.printstacktrace() way, @ least you'll see there's problem if exception occurs. another approach re-throw exceptions upper-level code. e.g. if method (in sample code is) declares throw ioexception , there's nothing should worry about. let upper-level code worry it.
