• Are there plans to make a non-programming general version of StackOverFlow like Yahoo Answer! [close

  - by RoboShop

  Firstly, I would like to say I think StackOverflow is a really great website, not just from a content perspective, but from a design perspective. The UI is designed in a way that makes it easy to use and the points are great incentives to be a productive part of the community. I was wondering, is there a part of the site, or maybe is there plans to make a new site, which is not programming driven. Like a general knowledge site but with StackOverflow as the engine. I use sites like Yahoo Answer! and they can be useful. But I think the main difference between Stack Overflow and Yahoo Answer is that Yahoo Answer encourages content indiscriminately, whereas Stack Overflow is disciplined enough that it only encourages content that are helpful or useful. I find it great that I can load up a question and the best answer pops up immediately, and the bad answers are voted down. Thanks

• Unique keys for Sphinx along three vectors instead of two

  - by Brendon Muir

  I'm trying to implement thinking-sphinx across multiple 'sites' hosted under a single rails application. I'm working with the developer of thinking-sphinx to sort through the finer details and am making good progress, but I need help with a maths problem: Usually the formula for making a unique ID in a thinking-sphinx search index is to take the id, multiply it by the total number of models that are searchable, and add the number of the currently indexed model: id * total_models + current_model This works well, but now I also through an entity_id into the mix, so there are three vextors for making this ID unique. Could someone help me figure out the equation to gaurantee that the id's will never collide using these three variables: id, total_models, total_entities The entity ID is an integer. I thought of: id * (total_models + total_entities) + (current_model + current_entity) but that results in collisions. Any help would be greatly appreciated :)

• How Do I Programmatically Check if a WordPress Plugin Is Already Activated?

  - by Volomike

  I know I can use activate_plugin() from inside a given, active plugin in WordPress, to activate another plugin. But what I want to know is how do I programmatically check if that plugin is already active? For instance, this snippet of code can be temporarily added to an existing plugin's initial file to activate a partner plugin: add_action('wp','activatePlugins'); function activatePlugins() { if( is_single() || is_page() || is_home() || is_archive() || is_category() || is_tag()) { @ activate_plugin('../mypartnerplugin/thepluginsmainfile.php'); } } Then, use a Linux command line tool to spider all your sites that have this code, and it will force a page view. That page view will cause the above code to fire and activate that other plugin. That's how to programmatically activate another plugin from a given plugin as far as I can tell. But the problem is that it gets activated over and over and over again. What would be great is if I had an if/then condition and some function I could call in WordPress to see if that plugin is already activated, and only activate it once if not active.

• Prevent DTD download when parsing XML, redux

  - by harpo

  I have a folder full of XHTML files, and a console program to process them. The problem is, it doesn't work when I'm offline, because The remote name could not be resolved: 'www.w3.org' A number of sites, including this one, say to set the XmlResolver to null. That is not not working. I have tried setting the XmlResolver to null every way that I can think of: in the XmlDocument, in XmlTextReader, and in the XmlReaderSettings. I believe that it's just creating a default instance. I have also tried implementing my own XmlResolver, but I don't know what to return for external items. public class NonXmlResolver : XmlUrlResolver { public override object GetEntity( Uri absoluteUri, string role, Type ofObjectToReturn ) { if ( absoluteUri.Scheme == "http" ) throw new Exception("What you talking 'bout, Willis?"); else return base.GetEntity( absoluteUri, role, ofObjectToReturn ); } } The documents do not use any special entities, only pure XML. This is possible, right?

• Flash uploader that can handle >2GB files?

  - by Alvin SMith

  Is there an open source Flash uploader that can handle files larger than 2 GB? ASP.net implementations like SlickUpload are not an option, and SWFUpload (and others that I've seen) do not handle files larger than 2 GB. Nor is requiring the user to have Java installed to run applets. This would be for both IE and Firefox. I've seen a couple "large file transfer" sites that have a Flash uploader and claim to go past the 2GB limit (which is the limit for http uploads for most browsers) so I know it is technically possible.

• jsonp cross domain only working in IE

  - by iboeno

  EDIT: At first I thought it wasn't working cross domain at all, now I realize it only works in IE I'm using jQuery to call a web service (ASP.NET .axmx), and trying to us jsonp so that I can call it across different sites. Right now it is working ONLY in IE, but not in Firefox, Chrome, Safari. Also, in IE, a dialog pops up warning "This page is accessing information that is not under its control..." Any ideas? Here is the code: $.ajax({ type: "POST", url: "http://test/TestService.asmx/HelloWorld?jsonp=?", dataType: "jsonp", success: function(data) { alert(data.prop1); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(XMLHttpRequest.status + " " + textStatus + " " + errorThrown); } }); And the server code is: [ScriptService] public class TestService : System.Web.Services.WebService{ [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public void HelloWorld() { string jsoncallback = HttpContext.Current.Request["jsonp"]; var response = string.Format("{0}({1});", jsoncallback, @"{'prop1' : '" + DateTime.Now.ToString() + "'}"); HttpContext.Current.Response.Write(response); } }

• Should I integrate FedEx or UPS into my Rails app?

  - by MikeH

  I'm working on integrating a shipping solution into a Rails ecommerce app. We're only going to use one shipping provider. So the question is: FedEx or UPS? I'm wondering what Rails developers think about the tech side of this question. What do you think about the APIs, ease of integration, focus on developer's needs between FedEx and UPS? I was leaning towards FedEx, but from looking at the developers resources sections of both sites, it seems that UPS might be more developer friendly. Also, I'm going to be using Shopify's active_shipping gem: http://github.com/Shopify/active_shipping And I also based my app off the Spree Ecommerce solution, but I don't think that's particularly relevant to the question. Spree wrote a wrapper to integrate active_shipping with the Spree system. Thanks.

• Best free site/blog to put video tutorial

  - by nash

  Hi, i am planning to upload a video tutorial on a particular software technology. The size of the videos will be around 600 MB's to say 1 GB. I am putting it for free for anyone to download. Is there any site/blog where i can put it.I am planning to divide the videos in parts and zip them. Does blogger or any other cms allow me to upload to there sites and put download links? Or is buying web space the only option? I am not keen on using youtube as i clearly want the user to download by clicking on links and not watch them online. Also i was thinking of just uploading the videos on rapidshare/megaupload/mediafire... and put just links on a blogger post. Any suggestion from you guys?

• generic async loading method for page web scripts?

  - by boomhauer

  The google analytics code went to an async load model some time back. I've noticed that a lot of the other scripts I use on many sites are causing slow load times - specifically the addthis script and the facebook like button. I'm noticing that the slow load times of these scripts is causing the google bot to calc my page loadtimes as being much slower than previously. I'd like to know if there is a standard/generic way of causing these scripts to load async as well, or perhaps a pointer to someone who has done the work for this already. Seems this would be a popular thing to do, but not much luck searching around.

• Where can I find a large body of *Python3* source code?

  - by Ira Baxter

  I'm testing a Python parser. I have Python 2.6/2.7 firmly under control, and some good (large) code samples on which I've tested it. I'm interested in testing my Python3 variant. I've been to various Python open source web sites (e.g., http://pythonsource.com/), which list lots of packages, but they are pretty unclear as whether these are Python 2.x vs 3.x source files. The several samples that I downloaded all turned out to be Python 2.x. Where can I find a number of large Python 3 software source codes? I don't really want 1000 little separate Python3 files; I prefer big applications.

• Continuous Deployment with a C#/ASP.NET website?

  - by Amber Shah

  I have a website in C#/ASP.NET that is currently in development. When we are in production, I would like to do releases frequently over the course of the day, as we fix bugs and add features (like this: http://toni.org/2010/05/19/in-praise-of-continuous-deployment-the-wordpress-com-story/). If you upload a new version of the site or even change a single file, it kicks out the users that are currently logged in and makes them start over any forms and such. Is there a secret to being able to do deployments without interfering with users for .NET sites?

• java get file paths

  - by user283188

  hey everybody, I have a jsp page which contains the code which prints all files in a given directory and their file paths. The code is if (dir.isDirectory()) { File[] dirs = dir.listFiles(); for (File f : dirs) { if (f.isDirectory() && !f.isHidden()) { File files[] = f.listFiles(); for (File d : files) { if (d.isFile() && !d.isHidden()) { System.out.println(d.getName()+ d.getParent() + (d.length()/1024)); } } } if (f.isFile() && !f.isHidden()) { System.out.println(f.getName()+ f.getParent() + (f.length()/1024)); } } } The problem is that it prints the complete file path, which when accessed from tomcat is invalid. For example, the code spits out the following path: /usr/local/tomcat/sites/web_tech/images/scores/blah.jpg and I want it to only print the path up to /images ie /images/scores/blah.jpg I know I could just mess around with an actual string, ie splitting it or string matching, but is there an easier way to do it? Thanks

• Performance optimization for SQL Server: decrease stored procedures execution time or unload the ser

  - by tim

  We have a web service which provides search over hotels. There is a problem with performance: a single request to the service takes around 5000 ms. Almost all of the time is spent in database by executing storing procedures. During the request our server (mssql2008) consumes ~90% of the processor time. When 2 requests are made in parallel the average time grows and is around 7000 ms. When number of request is increasing, the average time of response is increasing as well. We have 20-30 requests per minute. Which kind of optimization is the best in this case having in mind that the goal is to provide stable response time for the service: 1) Try to decrease the stored procedures execution time 2) Try to find the way how to unload the server It is interesting to hear from people who deal with booking sites.

• Single SingOn - Best practice

  - by halfdan

  Hi Guys, I need to build a scalable single sign-on mechanism for multiple sites. Scenario: Central web application to register/manage account (Server in Europe) Several web applications that need to authenticate against my user database (Servers in US/Europe/Pacific region) I am using MySQL as database backend. The options I came up with are either replicating the user database across all servers (data security?) or allowing the servers to directly connect to my MySQL instance by explicitly allowing connections from their IPs in my.cnf (high load? single point of failure?). What would be the best way to provide a scalable and low-latency single sign-on for all web applications? In terms of data security would it be a good idea to replicate the user database across all web applications? Note: All web applications provide an API which users can use to embed widgets into their own websites. These widgets work through a token auth mechanism which will again need to authenticate against my user database.

• How do you limit a page with multiple flash mp3 players to play one at a time?

  - by Andrew.S

  I am working with the open source flash player at http://flash-mp3-player.net/ and I am trying to figure out how to limit one sound file at a time. I know this has been done on a number of sites but I am unsure how to approach it. Scenario: A page has five different instances of the flash player. The user is litening to one song but clicks on another to listen to it. Goal: The first audio file automatically stops while the second starts playing instead of both playing at the same time. Do I need to have some sort of javascript handler than interacts with the swf or something?

• Debugging of native code

  - by graham.reeds

  I have a C# Service that is calling a C DLL that was originally written in VC6. There is a bug in the DLL which I am trying to inspect. After having a nightmare trying to get debug to work I eventually added the dll to the VS2005 solution containing the C# Service and added the necessary _CRT_SECURE_NO_WARNINGS. The debug version of the service is registered using 'installutil.exe' tool. I can get the debugger to break just before the line where the dll is entered via a call to System.Diagnostics.Debugger.Break();. I found some instruction on the net regarding stepping into debugging unmanaged code, and enabled the 'Enable unmanaged code debugging' check box, I've also tried turning on the Options-Debugging-Native 'Load DLL exports' and 'Enable RPC Debugging' (even though it's not COM). I've also copied the debug dll and .pdb to the same bin directory as the However the unmanaged code is not being stepped into which is what I really need. UPDATE: I found the Debugging Type in the DLL properties and set it to 'Mixed' as per suggestion on several sites but to no avail.

• Does PHP session conflict with Share-Nothing-Architecture?

  - by Morgan Cheng

  When I first meet PHP, I'm amazed by the idea Sharing-Nothing-Architecture. I once in a project whose scalaiblity suffers from sharing data among different HTTP requests. However, as I proceed my PHP learning. I found that PHP has sessions. This looks conflict with the idea of sharing nothing. So, PHP session is just invented to make counterpart technology of ASP/ASP.NET/J2EE? Should high scalable web sites use PHP session?

• Resources for TDD aimed at Python Web Development

  - by Null Route

  I am a hacker not and not a full-time programmer but am looking to start my own full application development experiment. I apologize if I am missing something easy here. I am looking for recommendations for books, articles, sites, etc for learning more about test driven development specifically compatible with or aimed at Python web application programming. I understand that Python has built-in tools to assist. What would be the best way to learn about these outside of RTFM? I have searched on StackOverflow and found the Kent Beck's and David Astels book on the subject. I have also bookmarked the Wikipedia article as it has many of these types of resources. Are there any particular ones you would recommend for this language/application?

• Thumbnail wont show up in Facebook link share

  - by Xander Aeder Putris

  I have been messing with Open Graph for hours and can't figure out why Facebook still wont let me show an image when I share a link to a new site I just launched. Even sites I built 5 years ago that have no clue of Open Graph show images so I have no idea why this new site wont allow it. I just need to launch this site and every time I post the url in my status update only text appears. I re sized the image to be 200px x 135px but that still doesn't work.. It can find the image but it wont show up. Please help me figure this thing out. I have a number of people sharing this page right now and no image shows up.. So embarrassing. Thank you in advance!

• Russian time zone changes

  - by Tim Post

  As many of you know, Russia has eleven time zones, and has (or will) cut two of them. It is possible that they may end daylight savings time altogether. Does anyone know if they have cut two time zones, and if daylight savings is now a thing of the past? If so, does daylight savings end in all time zones, or just some? I maintain some software that may need to be patched and can't find two news sites that agree on if they have, or have not implemented these changes.

• Clear Input onFocus with Google Custom Search

  - by Wes

  I'm moving a sites search over to google custom search. The old input for text looks like this: <input type="text" value="Search this website..." name="s" id="searchbox" onfocus="if (this.value == 'Search this website...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search this website...';}" /> Now I need to Have the attr 'name' as 'q', like so: <input type="text" value="Search this website..." name="q" id="searchbox" onfocus="if (this.value == 'Search this website...') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search this website...';}" /> The odd thing is that when I swap the name over to q, I'm unable to clear the search box on focus. Am I missing something super easy?

• Flash AS3 - Scroll dynamic textfield to a specific part just like HTML anchor

  - by Aamir Mahmood

  Hi, We are building a flash website with cms at the back end, and we are allowing admin to put anchors inside a content. Later we created a smaller version of the whole content to display just a small part and then [read more] button. Which add a new layer on top of every thing acting like a popup and it is populated with complete content. Now we would like to scroll that text inside popup to that portion which [read more] button was clicked. The most common example inside HTMl is go to top link in footer on most of the sites which move the whole document to top. Happy codding.

• Mobile Specific Site Development. Where to start?

  - by Andy

  I'm beginning the process of learning the ins and outs of developing sites for mobile web browsers. Are there any good resources/communities online that discuss mobile specific site development issues? My initial understanding is that to cover different phones you need to build one site that is enabled for browsers with the webkit engine (iphone, android, etc.) and another more basic site for other older browsers, is this assumption correct? Also what does developing for webkit mean exactly? How is it different than just using javascript/css/html? Is it the same except that you limit yourself to webkit specific functions and css? I looked on the webkit site, but it didn't explain it in those terms. Are there any other snafus I need to watch out for when developing for mobile browsers?
