  • Using system time directly to get random numbers

    - by Richard Mar.
    I had to return a random element from an array so I came up with this placeholder: return codes[(int) (System.currentTimeMillis() % codes.length - 1)]; Now than I think of it, I'm tempted to use it in real code. The Random() seeder uses system time as seed in most languages anyway, so why not use that time directly? As a bonus, I'm free from the worry of non-random lower bits of many RNGs. It this hack coming back to bite me? (The language is Java if that's relevant.)

  • Parsing XML elements with dynamic namespace prefix in PHP

    - by BugKiller
    I have the following XML ( you can say SOAP request ) : <SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope> I use the following code and it works fine : <?php $myRequest ='<SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope>'; $xml = simplexml_load_string($myRequest, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); $namespaces = $xml->getNameSpaces(true); $soapHeader = $xml->children($namespaces['SOAPENV'])->Header; $myHeader = $soapHeader->children($namespaces['NS'])->myHeader; echo (string)$myHeader->SourceID; ?> The Problem I know the prefix ( SOAPENV + NS ) , but the clients could change the prefix to whatever they want, so they may send me xml document that has ( MY-SOAPENV + MY-NS) prefixes. My Question How can I handle this since the namespace prefixes are not static , how can I parse it ? Thanks

  • a question related to Google Translate

    - by Robert
    Hi all, it works perfectly fine if I paste the following URL directly into my IE address bar: http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED it will translate some Chinese news pages into English ones. but if I call this address in a Java program like: Process q=Runtime.getRuntime().exec("cmd /c start http://translate.google.cn/translate?hl=zh-CN&sl=zh-CN&tl=en&u=http%3A%2F%2Fnews.baidu.com%2Fns%3Fword%3D%25B0%25C2%25B0%25CD%25C2%25ED"); It will only return to the Google translate main page. Wonder what went wrong there. and it would be great if you help me how to realize this(opening the Google translated result page simplying by supplying the URL,in a Java program). Many thanks.

Any help would be greatly appreciated!

  • How to override [Authorize] attribute in the MVC Web API?

    - by NullReference
    I have a MVC Web Api Controller that uses the [Authorize] attribute at the class level. This makes all of the api methods require authorization but I'd like to create an attribute called [ApiPublic] that overrides the [Authorize] attribute. There is a similar technique described here for normal MVC controllers. I tried creating an AuthorizeAttribute based of the System.Web.Http.AuthorizeAttribute but none of the overridden events are called if I put it on a api method that has the [Authorize] at the class level. Anyone have an idea how to override the authorize for the web api? [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public class ApiPublicAttribute : AuthorizeAttribute { protected override void HandleUnauthorizedRequest(System.Web.Http.Controllers.HttpActionContext actionContext) { base.HandleUnauthorizedRequest(actionContext); } public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext actionContext) { base.OnAuthorization(actionContext); } protected override bool IsAuthorized(System.Web.Http.Controllers.HttpActionContext actionContext) { return true; } }

  • URL rewrite to remove parameters

    - by samoyed
    Hello to all, I'm working on a site where all the pages are actually index.php + a 'name' parameter that is analyzed and loads the appropriate template and content. the homepage url is: http://www.some_site.com/?page=homepage 1. i was asked to "change" the homepage url to: http://www.some_site.com can i use url rewite and htaccess for that and if so, what should i write there? working on my local machine, i tried this code (mode rewrite is enabled): <IfModule mod_rewrite.c> Options +FollowSymLinks RewriteEngine On RewriteRule /index.php /index.php?page=homepage </IfModule> i would still need the 'name' parameter to be available to the php code of course, so i can load the template and css files. 2. it would be nice for other pages (not homepage) to be converted from (example) http://www.some_site.com/?page=products to: http://www.some_site.com/products this is less crucial. thanx in advance and have a nice day :-)

  • RewriteCond and RewriteRule in .htaccess

    - by RD
    I have a client folder located at http://www.example.com/client However, I've now installed SSL on the server, and want to add a permanent redirect using HTACCESS so that whenever /client is accessed, that it redirects to: https://www.example.com/client Anybody know how to do that? I've redirected my domains in the past like this: RewriteCond %{HTTP_HOST} ^example\.com$ [NC] RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301] RewriteCond %{HTTP_HOST} ^www.example\.com$ [NC] RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301] This should not affect the solution, but the site must still redirect to www.example.com FIRST, and then to https://www.example.com/client if for example, http://www.example.co.za/client is entered.

  • MySQL: Selecting One Record When Others Have Same Data

    - by LoganFrederick
    I have a table of cities that all share the same area code: 367 01451 Harvard Worcester Massachusetts MA 978 Eastern 368 01452 Hubbardston Worcester Massachusetts MA 978 Eastern 369 01453 Leominster Worcester Massachusetts MA 978 Eastern The table has multiple area codes, all with multiple cities. What I'd like to do is only select one city from each area code and delete any extra cities from duplicate area codes. What would be the best query to accomplish this? I believe: http://stackoverflow.com/questions/596629/mysql4-sql-for-selecting-one-or-zero-record Is coming close to what I need but didn't quite get what/how those answers were working. Note The "978" row is the "area_code" row, table name is "zip_code".

  • How to facebook getuser() after login with javascript SDK

    - by user1848205
    So I have to ask for extended permission by clicking the enter button, but after the login is necessary to refresh the page in order to display the app. Here's my code: <?php require 'facebook.php'; $facebook = new Facebook(array( 'appId' => '< THE APPID >', 'secret' => '< THE SECRET >', 'cookie' => true, )); $user = $facebook->getUser(); if ($user) { try { $user_profile = $facebook->api('/me'); } catch (FacebookApiException $e) { error_log($e); $user = null; } } ?> <body> <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : '< THE APPID >', status : true, cookie : true, xfbml : true }); // Additional initialization code such as adding Event Listeners goes here $('#btn-enter').click(function(){ login(); }); }; (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); function login() { FB.login(function(response) { if (response.authResponse) { // connected } else { // cancelled } //}); }, {scope: 'read_friendlists,friends_photos,publish_stream'}); } </script> <?php if ($user): ?> <!--Here is my APP--> <?php else: ?> <a id="btn-enter">Enter</a> <?php endif ?> Is there a better way to do this ? What works for me is: function login() { FB.login(function(response) { if (response.authResponse) { top.location.href='https://the_app_url'; } else { } //}); }, {scope: 'read_friendlists,friends_photos,publish_stream'}); } But this causes the entire page to refresh and is not 'elegant' per se...
