  • Creating files on a time (hourly) basis

    - by Yaniv
    Hi there, I experimenting with twitter streaming API, I use Phirehose to connect to twitter and fetch the data but having problems storing it in files for further processing. Basically what I want to do is to create a file named date("YmdH")."."txt" for every hour of connection. Here is how my code looks like right now (not handling the hourly change of files) public function enqueueStatus($status) $data = json_decode($status,true); if(isset($data['text'])/*more conditions here*/) { $fp = fopen("/tmp/$time.txt"); fwirte ($status,$fp); fclose($fp); } Help is as always much appreciated :)

  • Retrieve a cross domain RSS(xml) through Javascript

    - by Ajay
    I have seen server side proxy workarounds for retrieving rss (xmls) from cross-domains. In fact this very question addressess my same problem but gives out a different solution. I have a constraint of do not use a proxy to retrieve rss feeds. And hence the Google AJAX Feed API solution also goes out of picture. Is there a client-only workaround for this problem. JSONP is the solution for requests that respond with JSON output. But here, I have RSS feeds which can respond with pure xml . How do I solve the problem.

  • OpenGL game written in C with a Cocoa front-end I want to port to Windows

    - by Philip
    Hello, I'm wondering if someone could offer me some tips on how to go about this. I have a MacOS X OpenGL game that is written in very portable C with the exception of the non-game-play GUI. So in Cocoa I set up the window and OpenGL context, manage preferences, registration, listen for keystrokes etc. But all of the drawing and processing of input is handled in nice portable C. So I want to port to Windows. I figured the obvious way to go about was to use the Win32 api. Then I started to read a primer on Win32 and began to wonder if maybe life isn't too short. Can I do this in C# (without converting the backend to C#)? I'd rather devote the time to learning C# than Win32. Any suggestions would be most welcome. I really don't know a lick about Windows. The last version I regularly used was 3.1...

  • Pagination using Ajax in jquery Datatables

    - by kshtjsnghl
    I am using dataTables plugin for a table on a page I am working on. Its basically fetching rows through an ajax call and in this ajax call, I send the search params that the user selects and the page number required. I need the Next, Previous, First and Last buttons to also fire the same ajax call, but with different page numbers, as the back-end interceptor depends on the page number. This api call would return total no. of rows(say 1000) belonging for these search params and the rows with the page size( say 50). Is there any way, I can use data table to do this?

  • Using user editable image URL in application. Security issues.

    - by sharas
    Hi there. I am writing an application where users are required to show their photo, however as my server resources are very limited I can not let them upload it to the server. So I have three major questions: 1. How to properly validate photo URL? At least I can validate with regexp, however I need to check for file ending: `validates_format_of :photo_url, :with => URI::regexp(%w(http https))` 2. Security issues? XSS? Even I validate the picture at the moment of creation, hacker can replace image with malicious stuff anytime. 3. Maybe there are free asset stores with API?

  • Should member variables of global objects be made global as well?

    - by David Wong
    I'm developing plugins in Eclipse which mandates the use of singleton pattern for the Plugin class in order to access the runtime plugin. The class holds references to objects such as Configuration and Resources. In Eclipse 3.0 plug-in runtime objects are not globally managed and so are not generically accessible. Rather, each plug-in is free to declare API which exposes the plug-in runtime object (e.g., MyPlugin.getInstance() In order for the other components of my system to access these objects, I have to do the following: MyPlugin.getInstance().getConfig().getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); , which is overly verbose IMO. Since MyPlugin provides global access, wouldn't it be easier for me to just provide global access to the objects it manages as well? MyConfig.getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); Any thoughts? (I'm actually asking because I was reading about the whole "Global variable access and singletons are evil" debates)

  • So I dynamically load a jar at runtime how do I use it?

    - by justinhj
    So question 194698 shows how to load a jar file at runtime and you can load individual named classes and get a Class object. Now my problem is I want to be able to cast those Classes to the types they really are, but I can't because I can't use an import since the whole point is to load it at runtime rather than compile time. It seems like the way to go is to use reflection to discover the functions and field names, but that seems brittle since the API in the jar files could change and the code won't break until it is run. Is there a better way?

  • Custom marker changed to a black rectangle after clicking the marker few times on Google Map v2

    - by RajeevSahu
    Hi, How to avoid displaying black rectangles over the Custom marker. Actually Custom markers changed to a black image rectangle after clicking the marker few times on Google Map. I am using API V2. I am using Nokia N97 to display my google map with Custom markers. I am not sure, but I guess because of wi-fi connectivity, some times the connection lost, so at that moment when I click the Markers, they turned to black image rectangles. Any idea, how to avoid this thing. Thanks...

  • fstream file I/O question

    - by Konrad
    Hi, I am trying to work out if I need to call close on a fstream object if the intial open failed. i.e. std::fstream strm; strm.open( "filename" ); if( ! strm.fail() ) { // Do something strm.close(); // [1] } strm.close(); // [2] Where should close be called here - should it always be called [2] or only if the open succeeds[1]? I may be going over the top here, but coming from the Windows API way of typically doing this I have CloseHandle( ... ); embedded in my mind :-)

  • Google App Engine, Java, and HTTP Performance

    - by polyclef
    A friend and I are currently working on a turn-based game with chat with both desktop browser and Android clients, with Google App Engine as the server. We're using the Java API for GAE and using HTTP for communication with the server. We've implemented simple chat functionality, and we're getting undesirable latencies 1-3 seconds from both the browser and Android clients while just posting simple one-word chat messages. My friend thought it would be best to use XMPP instead of HTTP, but we want to use a Google Accounts cookie for authentication from the Android client, and according to the GAE documentation, XMPP clients cannot use a Google Accounts cookie and must use the user's password. Does anyone have any suggestions as to where the latency might be coming from, how to troubleshoot it, and/or what to do about it? Also, is anyone aware of any opensource implementations of chat (or something similar) on GAE done in Java? Can't seem to find any.

  • Prototype - DOM Traversal with up()

    - by Jason McCreary
    I have the following structure: <form> <div class="content"> ... </div> <div class="action"> <p>Select <a class="select_all" href="?select=1" title="Select All">All</a></p> </div> </form> I am using Prototype's up() to traverse the DOM in order to find the <form> element in respect to the a.select_all. However the following doesn't work: select_link.up('form'); // returns undefined Yet, this does. select_link.up().up().up(); // returns HTMLFormElement Clearly this is an ancestor of a.select_all. The API Docs state Element.up() supports a CSSRule. What am I missing here?

  • How do I use python wx:Config to access the Windows registry?

    - by GreenAsJade
    I've read http://wxpython.org/docs/api/wx.ConfigBase-class.html I've done some basic things like the appended. What I can see is that Config.Create() returns me some sort of configuration object, which has information about python in it. But clearly that's not what I'm looking for: I seem to be missing the magic to say "give me a Config that is the Windows Registry"... Thanks! GaJ import wx from wx import Config app=wx.App(False) config=Config.Create() config.HasGroup("HKEY_CURRENT_USER") False config.GetFirstEntry() (0, u'', -1) config.GetFirstGroup() (1, u'PythonCore', 1) config.GetNextGroup(1) (0, u'', -1) config.GetNumberOfGroups() 1 config.GetPath() u'' config.HasEntry("PythonCore") False config.GetFirstGroup() (1, u'PythonCore', 1)

  • Access uploaded file in JSON encoded data

    - by okello
    I've encoded my form data into JSON. This has been achieved by the following ExtJS store configuration: Ext.define('XXX.store.Registration', { extend: 'Ext.data.Store', model: 'XXX.model.Registration', autoLoad: true, pageSize: 15, autoLoad: { start: 0, limit: 15 }, proxy: { type: 'ajax', api: { create: './server/registration/create.php', read: './server/registration/get.php', update: './server/registration/update.php', destroy: './server/registration/destroy.php' }, reader: { type: 'json', root: 'registrations', successProperty: 'success' }, writer: { type: 'json', writeAllFields: true, encode: true, root: 'registrations' } } }); My server side code has been implemented in PHP. I can access the encoded form fields by using the field name as a key, as exemplified below: $reg = $_REQUEST['registrations']; $data = json_decode(stripslashes($reg)); $registerNum = $data->registerNum; $folioNum = $data->folioNum; One of the fields in my form is a fileuploadfield. How can I access the uploaded file from the uploaded JSON. Any assistance will be highly appreciated.

  • Why are configuration arrays acceptible parameters in PHP and Javascript?

    - by RenderIn
    In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

  • C++ execution error: This application has requested the Runtime to terminate it in an unusual way.

    - by user1846547
    I am trying to run a C++ program and am getting the following error message when I try to run the program using - Codeblocks IDE and SQL API: "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Process returned 3 (0x3) execution time : 7.547 s Press any key to continue." The program compiles fine but on execution throws this error. My current OS is Windows server 2003 - SP2 (32 bit). Also program compiles and executes fine on Windows XP (32 bit) without any hassles. I checked the services (services.msc) running on my XP machine and compared with Windows server 2003 and found the settings same. Can someone please have a look and help me resolve the issue? thanks, Dhruv

  • How to create a voldemort store?

    - by Pankaj
    I am trying to understand the Voldemort java API. I am new to non relational databases, so as I understand, Voldemort's store can be compared to a table in relational model. I saw the following code in the documentation. String bootstrapUrl = "tcp://localhost:6666"; StoreClientFactory factory = new SocketStoreClientFactory(new ClientConfig().setBootstrapUrls(bootstrapUrl)); // create a client that executes operations on a single store StoreClient client = factory.getStoreClient("test"); Here, we got a Store client based on the an existing store (test). How can I actually create a store for Voldemort through java?

  • Oauth2 External Browser Request - App Launches, Credentials received, Browser Not Updated

    - by Michael Drozdowski
    I'm using an external browser request to authenticate myself with the SoundCloudAPI in OSX. My app launches, and has a button that opens an external browser window to authenticate against SoundCloud. When I click "connect" in the new window, I get a "External Protocol Request" that is consistent with my custom launch URI scheme. Clicking this loads the app, and it gets the correct credentials. The trouble is, the browser window never changes - it simply says that it's connecting forever. There is no "connection confirmed" alert coming from SoundCloud. I know I'm logged in because I can make the correct calls to the API to get things such as my username. Why isn't the browser confirming the connection or dismissing? The same thing happens if I load the authentication in an internal WebView in the app.

  • Why Camera.setParameters(Camera.Parameters) has no effect on Sony-Ericsson X10 and Droid?

    - by mobilekid
    Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid? For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders... mParameters.set("rotation", orientation); mParameters.set("jpeg-quality", img_quality); mParameters.set("picture-size", "1024x768"); mCamera.setParameters(mParameters); Could you suggest an alternative way of achieving the same? Thanks.

  • Android app using 2.x APIs that will also run on 1.x

    - by Adam Haile
    I'm working on an Android app in which I would like to use multi-touch. However, I do not want to completely leave out those still running a 1.x OS phone. How do you program the app so that you can use the 2.x multi-touch APIs (or any other higher level API for that matter) and still allow it to gracefully degrade on 1.x systems. If you create a project in Eclipse for 1.x can you even still access the 2.x APIs? Basically I want it to show up in the marketplace and work on all 1.6 and higher phones and just allow access to the higher level functionality if available. Also, if anyone can point me to any data on the number of 1.x devices vs. 2.x devices in use, it would be greatly appreciated.

  • How can I print a text in two columns using Java Swing?

    - by Jonas
    I have a longer text saved in a String. I would like to print the text in two columns on a single page. How can I do this using Java Swing? I don't understand how I can wrap the text when it's time to use a new line. I have read Lesson: Printing in the Java tutorial, but I haven't found any useful methods for working with text or Strings except FontMetrics. Is there any good methods in the Java API for this or is there any good library I can use for this?

  • Reason for .Net UI Element Thread-restriction

    - by Charles Bretana
    We know that it is not possible to execute code that manipulates the properties of any UI element from any thread other than the thread the element was instantiated on... My question is why? I remember that when we used COM user interface elements, (in COM/VB6 days), that all UI elements were created using COM classes and co-classes that stored their resources using a memory model referred to as Thread-Local-Storage (TLS) , but as I recall, this was required because of something relaetd to the way COM components were constructed, and should not be relevant to .Net UI elements. Wha's the underlying reason why this restriction still exists? Is it because the underlying Operating System still uses COM-based Win32 API classes for all UI elements, even the ones manipulated in a managed .Net application ??

  • Why are Objective-C instance variables declared in an interface?

    - by Chase
    I'm just getting into Objective-C (Java is my primary OO language). Defining an object's instance variables in the interface instead of the class seems strange. I'm used to an interface being a public API definition with nothing besides method signatures (not counting constants here). Is there some reason that state is defined in an interface (even if it is private) and behaviour is defined in a class. It just seems odd that since objects are state+behavior that the definition would be split into two separate places. Is it a design benefit is some way? A pain in the rear issue that you are just forced to deal with in Objective-C? A non-issue, just different? Any background on why it's done this way? Or can you put object state in a class and I just haven't hit that part in my book yet?
