• How can you buffer two online videos alternately while playing one of them?

  - by Rajats1234

  On my website, I want my user to be able to launch video 2 at any point in the middle of video 1 without waiting or refreshing the window. How can I buffer the two videos such that I buffer video 1 enough to let it start playing, and then buffer just enough of video 2 that if the user launches it at any point, he does not have to wait to view its first few seconds, and then I can come back and buffer the rest of video 1? If this is not possible, I could also look at buffering video 1 and 2 in parallel while playing only video 1. Thanks!

• Simple, Custom Parsing with c++

  - by bradkovach

  Hi! I have been reading SO for some time now, but I truly cannot find any help for my problem. I have a c++ assignment to create an IAS simulator. Here is some sample code... 0 1 a 1 2 b 2 c 3 1 10 begin 11 . load a, subtract b and offset by -1 for jump+ 11 load M(0) 12 sub M(1) 13 sub M(3) 14 halt Using c++, I need to be able to read these lines and store them in a "memory register" class that I already have constructed... For example, the first line would need to store "1 a" in register zero. How can I parse out the number at the line beginning and then store the rest as a string? I have setup storage using a class that is called using mem.set(int, string);. int is the memory location at the beginning of the line and string is the stored instruction.

• How to keep a Generic list unmodified when its copy is modified?

  - by user1801934

  When I create a copy of the original list lstStudent in lstCopy and send the lstCopy to modification function, the lstStudent also gets modified. I want to keep this list unmodified. List<Student> lstStudent = new List<Student>(); Student s = new Student(); s.Name = "Akash"; s.ID = "1"; lstStudent.Add(s); List<Student> lstCopy = new List<Student>(lstStudent); Logic.ModifyList(lstCopy); // "Want to use lstStudent(original list) for rest part of the code" public static void ModifyList(List<Student> lstIntegers) { foreach (Student s in lstIntegers) { if (s.ID.Equals("1")) { s.ID = "4"; s.Name = "APS"; } } }

• Application crashes when popViewControllerAnimated is called while scrolling

  - by Aldrich

  In one screen I have a custom toolbar with a "close" button in it, and a UIScrollView. In the screen that preceded this one I had pushed the current screen into the navigation stack. I had also disabled the navigation toolbar for a larger display area and so the close button would instead be used to call: - (void)doClose { [self.navigationController popViewControllerAnimated:YES]; } Now here's the problem: the application crashes when the close button is pressed, while the UIScrollView is moving. Here's the debugger stack trace: 0 __forwarding__ 1 __forwarding_prep_0___ 2 -[UIToolbarButton setHighlighted:] 3 -[UIControl(Static) _unhighlight] 4 __NSFireDelayedPerform ... and I do have the following line in the debugger console: *** -[CALayer setOpacity:]: message sent to deallocated instance 0x718d250 (sometimes setOpacity would be setNeedsDisplay or something related) There won't be any crashes while the scrollview is at rest. What is happening?

• UIScrollView with over 100 images

  - by tikkips

  I have implemented a UIScrollView on the iPhone that contains 100 image slots which I fill only the currently visible page, the one before it, and the one after it as the user scrolls. Everything works fine until we get up to image 97 or 98, the entire view disappears! The only thing I can do at that point is navigate back to the previous view. Nothing works as far as the scroll view after this. I am not receiving any memory warnings an the rest of the app functions fine. Any ideas? Has anyone created a UIScrollView in paging mode with over 100 pages? Rick

• Rails routes looking for show action

  - by user1334345

  I am pretty new to rails and basically I want to make a user registration form. I am currently using rails 3.2.3 Basically I want to make basic routes like user/register on top of basic REST route for user. Here are my routes.rb resources :user do collection do get 'register' end end And here are my rake routes: register_user_index GET /user/register(.:format) user#register user_index GET /user(.:format) user#index POST /user(.:format) user#create new_user GET /user/new(.:format) user#new edit_user GET /user/:id/edit(.:format) user#edit user GET /user/:id(.:format) user#show PUT /user/:id(.:format) user#update DELETE /user/:id(.:format) user#destroy From my understanding, since register user is on top of show, it should match with register first before going to show. However, when I try to do localhost:3000/user/register, it gives me this error: No route matches {:action="show", :controller="user"} Can somebody help me with this? Thanks!!

• Best practice: How to persist simple data without a database in django?

  - by Infinity

  I'm building a website that doesn't require a database because a REST API "is the database". (Except you don't want to be putting site-specific things in there, since the API is used by mostly mobile clients) However there's a few things that normally would be put in a database, for example the "jobs" page. You have master list view, and the detail views for each job, and it should be easy to add new job entries. (not necessarily via a CMS, but that would be awesome) e.g. example.com/careers/ and example.com/careers/77/ I could just hardcode this stuff in templates, but that's no DRY- you have to update the master template and the detail template every time. What do you guys think? Maybe a YAML file? Or any better ideas? Thx

• Threads in PHP.

  - by Muhammad Sajid

  Hello.. I am creating a web application using zend, here i create an interface from where user-A can send email to more than one user(s) & it works excellent but it slow the execution time because of which user-A wait too much for the "acknowledged response" ( which will show after the emails have sent. ) In Java there are "Threads" by which we can perform that task (send emails) & it does not slow the rest application. Is there any technique in PHP/Zend just like in Java by which we can divide our tasks which could take much time eg: sending emails. Thanks..

• Response.Redirect causes System.Threading.ThreadAbortException

  - by RandomBen

  When I use Response.Redirect(...) to redirect my form to a new page I get the error: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code My understanding of this is that the error is being caused by the webserver aborting the remainder of the page the response.redirect was called on. I know I can add a second parameter to Response.Redirect that is called endResponse. If I set endResponse to True I still get the error but if I set it to False then I do not. I am pretty sure though that that means the webserver is running the rest of the page I redirected away from. Which would seem to be inefficient to say the least. Is there a better way to do this? Something other than Response.Redirect or is there a way to force the old page to stop loading where I will not get a ThreadAbortException?

• Magento: Deduct Tax at Checkout for (most) countries

  - by towerofbabel

  I am working on a UK fashion store. The customer has a specific requirement - never add tax (VAT) at checkout; rather, have VAT built into the price, and deduct when applicable. The use case is that EU purchases will have no tax added at checkout - as the price includes it. And, rest of the world purchases will have the VAT deducted at the checkout. I can't see how to do this in Magento. I though to set up some negative values for tax rates, but that doesn't work. Any ideas?

  I must convert string of 1324312321 to array of integers in java this is fine. I could use integer parseint and string substring method but how do I repesent -12312312 to my original array of integer.. the fact that - is a char / string and convert to array of integer would alter the value ( even though I convert - to integer-equivalent , it would change the rest of 12312312) it must be an array of integers and how should I convert negative numbers and still keeep the same value somehow reminding me of two complements trick but i dont think i need to go down to binary level in my program.. any other trick for doing this? thanks!

• Static initialization of a struct with class members

  - by JS Bangs

  I have a struct that's defined with a large number of vanilla char* pointers, but also an object member. When I try to statically initialize such a struct, I get a compiler error. typedef struct { const char* pszA; // ... snip ... const char* pszZ; SomeObject obj; } example_struct; // I only want to assign the first few members, the rest should be default example_struct ex = { "a", "b" }; SomeObject has a public default constructor with no arguments, so I didn't think this would be a problem. But when I try to compile this (using VS), I get the following error: error C2248: 'SomeObject::SomeObject' : cannot access private member declared in class 'SomeObject' Any idea why?

• How can two programs talk to each other in Java?

  - by Arnon

  I want to ?reduce? the CPU usage/ROM usage/RAM usage - generally?, all system resources that my app uses - who doesn't? :) For this reason I want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which means it should call the update method (that i wrote) that found in the Main class. How can I call the update method in the Main program from the preferences program? To put it another way, is a way to build preferences window that take system resources just when the window appears? Is this approach - of separating programs and let them talk to each other (somehow) - the right approach for speeding up my programs?

• Store data in Ruby on Rails without Database

  - by snowmaninthesun

  I have a few data values that I need to store on my rails app and wanted to know if there are any alternatives to creating a database table just to do this simple task. Background: I'm writing some analytics and dashboard tools for my ruby on rails app and i'm hoping to speed up the dashboard by caching results that will never change. Right now I pull all users for the last 30 days, and re arange them so I can see the number of new users per day. It works great but takes quite a long time, in reality I should only need to calculate the most recent day and just store the rest of the array somewhere else. Where is the best way to store this array? Creating a database table seems a bit overkill, and i'm not sure that global variables are the correct answer. Is there a best practice for persisting data like this? If anyone has done anything like this before let me know what you did and how it turned out.

• Indexing an image in-between already made content

  - by Christophersson

  I have a pre-code page coded as follows: <div id="linearBg"> <div id="wrapper"> <div class="logo"></div> <div class="navigation"></div> <div class="video"></div> <div class="content"></div> </div> </div> Where linearBg is a gradient background, the back board of the website. Wrapper is the container for the inner div's, and the rest are content oriented. So i've already implemented this with styles and all sorts, but the thing is I want to add: <div class="watermark"></div> underneath/behind both the content and video div, sort of like a reverse watermark, I've tried z-indexing but i'm not an expert. Could you guide me on to do make this possible? Thanks in advance

• [WordPress 3.1.3] Sreen option is disabled when a plugin is activated

  - by RNorbe

  I'm pretty new to wordpress. I was assigned to create a custom plugin for one of our projects here. The plugin worked as expected and there is no problem activating/deactivating it. When I was exploring the admin panel I noticed that the screen option is off. I read from a blog somewhere that deactivating the plugin one by one to check which plugin has caused this. I did just this and found out that the custom plugin I created was the cause. My question is, is there way to check what have caused this? Some log file I can look into? There is no error message or warning when I activated the plugin and it is giving the output required. This is my first plugin, any advice will be helpful. Btw, this plugin will display a comment (most recent will be shown first) in a widget and there is prev/next navigation to go through the rest of the comments. Thanks, RNorbe

• Need complete picture of virtual adress space

  - by claws

  Hello, This image gives a good picture about Virtual Adress space. But it only says half of the story. It only gives complete picture of User Adress space ie.. lower 50% (or 75% in some cases). What about the rest 50% (or 25%) which is occupied by the kernel. I know kernel also has so many different things like kernel modules , device drivers, core kernel itself. There must be some kind of layout right? What is its layout? If you say its Operating System dependent. I would say, there are two major operating systems Windows & Linux. Please give answer for any one these.

• are shrink-to-fit table cells possible?

  - by Nano8Blazex

  Let's say I have a menu of a prespecified width... I want each menu item to shrink-to-fit with its contents, with the exception of ONE, which then fills up the remaining space in the menu. so like: Fill | item | item | item So far the closest I've come to achieving this effect is by using display:table-cell; in the css code for each menu item. But the problem is unless I define a width for the "item"s, they all expand to take up the same amount of width in the table. Fill | item | item | item | item Is there any way to have the item spaces shrink to fit the item and have the fill just fill up the rest of the div? I might not have asked this very clearly... I'll clarify if needed.

• Backbone.js "model" query

  - by Novice coder

  I'm a learning coder trying to understand this code from a sample MVC framework. The below code is from a "model" file. I've done research on Backbone.js, but I'm still confused as to exactly how this code pull information from the app's database. For example, how are base_url, Model.prototype, and Collection.prototype being used to retrieve information from the backend? Any help would be greatly appreciated. exports.definition = { config : { "defaults": { "title": "-", "description": "-" }, "adapter": { "type": "rest", "collection_name": "schools", "base_url" : "/schools/", } }, extendModel: function(Model) { _.extend(Model.prototype, { // Extend, override or implement Backbone.Model urlRoot: '/school/', name:'school', parse: function(response, options) { response.id = response._id; return response; }, }); return Model; }, extendCollection: function(Collection) { _.extend(Collection.prototype, { // Extend, override or implement Backbone.Collection urlRoot: '/schools/', name: 'schools', }); return Collection; } }

• What are the latest options in Java logging frameworks?

  - by sanity

  This question gets asked periodically, but I've long felt that existing Java logging frameworks were overcomplicated and over-engineered, and I want to see what's new. I have a more critical issue on my current project as we've standardized on JSON as our human-readable data encoding, and most logging frameworks I've seen require XML. I would really rather avoid using JSON for 95% of my apps configuration, and XML for the rest just because of the logging framework (truth be told, I hate XML used for anything other than text markup, its original intended purpose). Are there any hot new Java logging frameworks that are actively maintained, reasonably powerful, have a maven repo, can be reconfigured without restarting your app, and don't tie you to XML?

• Using concurrently 2 versions of boost

  - by idimba

  I'm using RHEL 5.3, which is shipped with gcc 4.1.2 and boost 1.33. There're some features I want, that are missing in the boost 1.33. Therefore the thought was to upgrade to fresh boost release 1.43. Is it possible to use concurrently some header-only library(s) from boost 1.43 and the rest from 1.33? For example I want to use unorded_map, which is missing in boost 1.33. Is it possible to use concurrently binary boost libraries from different releases?
