  • Simulating the accelerometer event feature in Firefox 3.6?

    - by leeand00
    I just downloaded Firefox 3.6 today and I noticed in the list of new features they have an Orientation API that can detect the direction that your laptop/computer is tilted. This is clearly a hardware feature of some sort; So if you don't have the hardware to do so is there any way of simulating it so that you can test it out on your projects?

  • Hooking the http/https protocol in IE causes GET requests to be sequential

    - by watsonmw
    I'm using the PassthruAPP method to hook into HTTP/HTTPS requests made by IE. It's working well for the most part, however I noticed a problem. Only one download thread is active at a time. I can see two IInternetProtocol objects getting created, but IE uses only one at a time. This is happening with IE7. The odd thing is that the problem occurs when overriding the existing default HTTP/HTTPS handler, even if the handler is not the one being used to make the request. E.g. Registering a handler for the HTTPS protocol will cause HTTP requests to be made sequentially, even though HTTP requests are not hooked. I installed Google Gears and it has the same problem. This always happens for the first few items on the page, but it seems that after the document complete is issued, concurrent downloads can occur again. For example Javascript code that is executed after the page has finished loading can load images concurrently just fine. One option is to try to IAT patch the 'IInternetProtocol' registered for HTTP requests, but Google Gears does this already and it has the same problem. I know installing a HTTP Proxy is another option, but I don't want to monkey with the users' HTTP Proxy settings if there another option.

  • Android ListAdapter Repaint

    - by xger86x
    Hi, i have the following problem. I fill a ListView with a custom ArrayAdapter with data from a BD. However, in background, i'm updating those datas from the info provided by an API, so the idea is when the update finish, the adapter shows the updated data instead its "old version". The problem is that when i do that, i notice a lag while the adapter is updating itself. Is the any efficient solution to avoid this? Thanks

  • Good Java graph algorithm library?

    - by Nick Fortescue
    Has anyone had good experiences with any Java libraries for Graph algorithms. I've tried JGraph and found it ok, and there are a lot of different ones in google. Are there any that people are actually using successfully in production code or would recommend? To clarify, I'm not looking for a library that produces graphs/charts, I'm looking for one that helps with Graph algorithms, eg minimum spanning tree, Kruskal's algorithm Nodes, Edges, etc. Ideally one with some good algorithms/data structures in a nice Java OO API.

  • datanucleus enhancer & javaw: "the parameter is incorrect"

    - by Riley
    I'm on windows XP using eclipse and the datanucleus enhancer for a gwt + gae app. When I run the enhancer, I get an error: Error Thu Oct 21 16:33:57 CDT 2010 Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect java.io.IOException: Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect at java.lang.ProcessBuilder.start(Unknown Source) at com.google.gdt.eclipse.core.ProcessUtilities.launchProcessAndActivateOnError(ProcessUtilities.java:213) at com.google.appengine.eclipse.core.orm.enhancement.EnhancerJob.runInWorkspace(EnhancerJob.java:154) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: java.io.IOException: CreateProcess error=87, The parameter is incorrect at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.<init>(Unknown Source) at java.lang.ProcessImpl.start(Unknown Source) ... 5 more I've had this problem before, and it was due to a long classpath. I just spent an hour and a half shortening my classpath by moving libraries around and even moving my eclipse install, but with no luck. Any ideas about where I should start to look for an answer? The error message doesn't include any information about what directory it's in or anything. It's kind of infuriating! Is it possible to make the output of javaw more verbose? Is it possible to get around this class-path size bug?

  • Single Sign On for WebServices, WCS, WFS, WMS (Geoserver), etc.

    - by lajuette
    I'm trying to implement a Single Sign On (SSO) for a web application. Maybe you can help me find a proper solution, give me a direction or tell me, that solutions already exist. The scenario: A GeoExt (ExtJS for geodata/map based apps) webapp (JavaScript only) has a login form to let the user authenticate himself. The authentication is not implemented yet, so i'm flexible with respect to that. After authenticating to the main webapp the user indirectly accesses multiple 3rd-party services like WebServices, GeoServer WFS, Google Maps, etc. These services might require additional authentication like credentials or keys. We are (so far) not talking about additional login screens, just some kind of "machine to machine"-authentication. The main problem: I'm unable to modify the 3rd party services (e.g. Google) to add a SSO mechanism. I'd like to have a solution that allows the user to log in once to have access to all the services required. My first idea was a repository that stores all the required credentials or keys. The user logs in and can retrieve all required information to acces sthe other services. Does anybody know of existing implementations, papers, maybe implementations of such services? Other requirements: The communication between the JS application and the repository must be secure. The credentials must be stored in a secure manner. But the JS app must be able to use them to access the services (no chance to store a decryption key in a JS-app securely, eh? *g).

  • Possible to use Python with Intel's Atom Developer SDK (C/C++)?

    - by Jordan Magnuson
    So I've made a game in Python and PyGame. Now I'm interested in submitting the game to Intel's March Developer Challenge. However, the developer challenge requires use of Intel's Atom Developer SDK (http://appdeveloper.intel.com/en-us/sdk), which only has API's for C and C++. I'm new to Python and PyGame, and have no experience in C or C++. My question is, would it be possible to somehow implement Intel's Atom SDK through/with/from a Python application (as the first link above suggests)? I've read up a little bit on embedding/extending Python into/with C, but I'm not entirely sure what to embed or where. I mean, I know I can do things like this in C: #include <Python.h> int main(int argc, char *argv[]) { Py_Initialize(); PyRun_SimpleString("from time import time,ctime\n" "print 'Today is',ctime(time())\n"); Py_Finalize(); return 0; } But what do I do about all my dependencies on Python and Pygame, for people that don't have those installed on their machines? Normally Py2Exe takes care of compacting the required dependencies (I've managed to package my game into an exe/zip), but how do I take care of that stuff in the context of embedding within C? Can I somehow work with py2exe on this, or do I need to do something entirely different for embedding within C? It seems like it would be a lot easier to go the route of extending Python with the C validation code, rather than trying to embed my whole game within C, but I think that's not an option, "because the library provided is currently only available as a Visual Studio 2008 '.lib'", meaning the application has to be compiled with Visual Studio...? Any help, thoughts, or ideas are much appreciated! You can find the complete SDK Developer's Guide on the intel site above, but here is their "Hello World" using the C Language API: #include <stdio.h> #include “adpcore.h” int main( int argc, char* argv[] ) { ADP_RET_CODE ret_code; const ADP_APPLICATIONID myApplicationID = {{ 0x12345678,0x11112222,0x33331234,0x567890ab}}; if ((ret_code = ADP_Initialize()) != ADP_SUCCESS ){ printf( “ERROR: exiting” ); exit( -1 ); } if (( ret_code = ADP_IsAuthorized( myApplicationId )) == ADP_AUTHORIZED ) printf( “Hello World” ); else printf( “Not authorized to run” ); exit 0; } 35 Page SDK Developer Guide: http:// appdeveloper.intel.com/sites/files/pages/SDK%20Developer%20Guide.pdf

  • How do I access SourceGear Web services using SOAP::Lite?

    - by user565793
    For some reason SourceGear provide an undocumented Web service on their installations. They actually ask developers to use the API instead because the Web service is kinda messy, but this is a problem in my case because I cannot use this API on a Perl environment, so their solution for my specific case is to use the Web service. This shouldn't be a problem. Using SOAP::Lite I have connected to several Web services in the past in the same way. But the lack of documentation is a major chaos if you don't know where the SOAP calls can be made. I only have an XML to decipher where to and how to make these calls. It would be great if a real SOAP genius could help me out in this. This is an example of the login call and the expected response: Request POST /fortress/dragnetwebservice.asmx HTTP/1.1 Host: velecloudserver Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://www.sourcegear.com/schemas/dragnet/LoginPlainText" <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <LoginPlainText xmlns="http://www.sourcegear.com/schemas/dragnet"> <strLogin>string</strLogin> <strPassword>string</strPassword> </LoginPlainText> </soap:Body> </soap:Envelope> Response HTTP/1.1 200 OK Content-Type: text/xml; charset=utf-8 Content-Length: length <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <LoginPlainTextResponse xmlns="http://www.sourcegear.com/schemas/dragnet"> <LoginPlainTextResult>int</LoginPlainTextResult> <strAuthTicket>string</strAuthTicket> </LoginPlainTextResponse> </soap:Body> </soap:Envelope> I'm looking for a way to be able to assemble this somehow. This is my Perl example: my $soap = SOAP::Lite -> uri ('http://velecloudserver/fortress/dragnetwebservice.asmx') -> proxy('http://velecloudserver/fortress/dragnetwebservice.asmx/LoginPlainText'); my $som = $soap->call('LoginPlainText', SOAP::Data->name('LoginPlainText')->value( \SOAP::Data->value([ SOAP::Data->name('strLogin')->value( 'admin' ), SOAP::Data->name('strPassword')->value('Adm1234'), ])) ); Any tip would be appreciated.

  • How to get absolute path from path with system path variables?

    - by The_Fox
    Is there an easy way to translate a path with system path variables to an absolute path? So %ProgramFiles%\Internet Explorer\hmmapi.dll becomes C:\Program Files\Internet Explorer\hmmapi.dll I like to know if there is an API call that can do this, or do I have to do this the hard way and detect %..% sequences and replace them with the appropriate environment variable?

  • How to set the preferred network interface in linux

    - by Mike Cooper
    I have my network set up like this. http://docs.google.com/Doc?docid=0AZ1YxuLE4djaZGhqN2s1NmRfMjhjNjc0Ym1meg&hl=en In words: I have a machine (Calcium, running Arch Linux) that has two network interfaces. eth0 is hoooked up to a router, and is gigabit. Eth1 is hooked up directly to the university network over 10Megabit. The router's uplink is hooked up to the university network as well, and it is also 10Megabit. Currently (I believe) all traffic on Calcium is going through eth0, through the router, regardless of whether it is internal or external. (How can I confirm this?) Ideally, traffic that is destined for the internal network (192.168.10.0/24) would travel over eth0 to the router, and wherever it is going. ALL other traffic should go over eth1.

  • Changing the working directory for a process remotely

    - by Michael
    I've got an application that has a bug right now, but we're unable to update the end-user to get the fix out. What a possible workaround would be is to change the working directory to the application's install directory, but from what I can tell, there's no way to do that outside of the program itself. Is there some sort of Windows API call that can change other processes' working directories, or is that not available due to security issues? I figure it's not possible.

    Im using the Twitter API to read the Favorites RSS, it generates the following output: http://vl3.co.uk/favs/getfavs.php I'm not sure why this file seems to be incorrect, doesnt come up in my RSS reader or render correctly in the browser. Can anyone shed any light on this? If the output is not valid RSS how can I make it so? Secondly I'd like to cache the RSS feed to then use something like Magpie RSS Parser.

  • Word XML to RTF conversion

    - by Chathuranga Chandrasekara
    I am in a need of programatically convert an Word-XML file into a RTF file. It has become a requirement, because of some third party libraries. Any API/Library that can do that? Actually the language is not a problem because I just need to work done. But Java, .NET languages or Python are preferred.

  • How to Add an Attachment to a User Story using Rally REST .NET

    - by user1373451
    We're in the process of porting our .NET Rally code from SOAP to the REST .NET API. One thing I'm looking to replicate is the ability to upload attachments. I'm following a very similar procedure as to the one outlined in this posting: Rally SOAP API - How do I add an attachment to a Hierarchical Requirement Whereby the image is read into a System.Drawing.Image. We use the ImageToBase64 function to convert the image to a byte array which then gets assigned to the AttachmentContent, which is created first. Then, the Attachment gets created, and wired up to both AttachmentContent, and the HierarchicalRequirement. All of the creation events work great. A new attachment called "Image.png" gets created on the Story. However, when I download the resulting attachment from Rally, Image.png has zero bytes! I've tried this with different images, JPEG's, PNG's, etc. all with the same results. An excerpt of the code showing the process is included below. Is there something obvious that I'm missing? Thanks in advance. // .... Read content into a System.Drawing.Image.... // Convert Image to Base64 format byte[] imageBase64Format = ImageToBase64(imageObject, System.Drawing.Imaging.ImageFormat.Png); var imageLength = imageBase64Format.Length; // AttachmentContent DynamicJsonObject attachmentContent = new DynamicJsonObject(); attachmentContent["Content"] = imageBase64Format; CreateResult cr = restApi.Create("AttachmentContent", myAttachmentContent); String contentRef = cr.Reference; Console.WriteLine("Created: " + contentRef); // Tee up attachment DynamicJsonObject newAttachment = new DynamicJsonObject(); newAttachment["Artifact"] = story; newAttachment["Content"] = attachmentContent; newAttachment["Name"] = "Image.png"; newAttachment["ContentType"] = "image/png"; newAttachment["Size"] = imageLength; newAttachment["User"] = user; cr = restApi.Create("Attachment", newAttachment); String attachRef = attachRef.Reference; Console.WriteLine("Created: " + attachRef); } public static byte[] ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format) { using (MemoryStream ms = new MemoryStream()) { image.Save(ms, format); // Convert Image to byte[] byte[] imageBytes = ms.ToArray(); return imageBytes; } }

  • Zyxel p-2602HW-1DA - LAN to WAN routing problems

    - by Garrett
    Hi Got a new router yesterday (due to new internet supplier) and now all my requests for my own server (local lan) is routed directly to the router instead of the server, when using dns. Ex. I have a website www.mysite.org running on my server at home (local lan). From work I can access it via www.mysite.org, which is great. But from home (local lan) my request's for www.mysite.org gets rerouted to the routers web admin interface My last router didn't do this. My new router is a Zyxel P-2602HW-1DA, my old one was a LinkSys WRT-54GC V. 2.0. There's a rather wierd WAN-LAN, WAN-WAN setup interface which I cant really comprehend yet and the docs are rather vague. Have anyone had the same problem and can anyone guide me to a solution, would nice not write the ip address everytime i need to access the server on local lan. :). Kind regards Garrett

  • Implement OAuth in Java

    - by phineas
    I made an an attempt to implement OAuth for my programming idea in Java, but I failed miserably. I don't know why, but my code doesn't work. Every time I run my program, an IOException is thrown with the reason "java.io.IOException: Server returned HTTP response code: 401" (401 means Unauthorized). I had a close look at the docs, but I really don't understand why it doesn't work. My OAuth provider I wanted to use is twitter, where I've registered my app, too.
