• How can I unit test an Android Activity that acts on Accelerometer?

  - by Corey Sunwold

  I am starting with an Activity based off of this ShakeActivity and I want to write some unit tests for it. I have written some small unit tests for Android activities before but I'm not sure where to start here. I want to feed the accelerometer some different values and test how the activity responds to it. For now I'm keeping it simple and just updating a private int counter variable and a TextView when a "shake" event happens. So my question largely boils down to this: How can I send fake data to the accelerometer from a unit test?

• Creating a Mac OS application that interacts with all text fields

  - by mjdth

  What would be the first step to creating an application for Mac OS X that would take user interaction from any text field in the system? A couple examples of apps that do this are TextExpander and Typinator. What I want to do would be using similar functions to access Text fields throughout the computer during user input to give other additional options, I'm just not sure where to even start in Xcode and with what type of project to use. Any help or links would be greatly appreciated! Thanks!

• Best Practice: Software Versioning

  - by Sebi

  I couldn't find a similar question here on SO, but if you find one please link. Is there any guideline or standard best practice how to version a software you develop in your spare time for fun, but nevertheless will be used by some people? I think it's necessary to version such software so that you know about with version one is talking about (e.g. for bug fixing, support, and so on). But where do I start the versioning? 0.0.0? or 0.0? And then how to I increment the numbers? major release.minor change? and should'nt any commit to a version control system be another version? or is this only for versions which are used in a productive manner?

• Timer applications running under lock on Windows Phone 7

  - by cpedros

  Under the current Windows Phone 7 Application Certification Requirements (pdf) applications running under lock must "stop any ... active timers" (section 6.3.1). However looking out on Marketplace there are a number of timer/stopwatch apps claiming to run under lock and also allow lock to be disabled in their settings. How are these apps certified or is there some loosening on the restrictions by Microsoft if the app allows the user to make that decision? Also some of these apps also suggest they continue even when the app is exited or when the device off. Is it the case that they are not truly running under these circumstances, i.e. the timers either start where they left off when reactivated, or perhaps use the OS time to work out the time elapsed between tombstoning and reactivation? In these circumstance I also presume it is not possible for the app to notify the user when the timer completes?

• NTLM Authentication fails ONLY with IE against 2k8 App server behind 2k8 IIS7 Reverse Proxy

  - by CptSkippy

  I'm developing an ASP.NET application for an intranet site that is using Windows/NTLM/WIA/whatever authentication. The application is hosted on a Windows 2k8 server but is accessed through a Reverse Proxy using IIs7 on another 2k8 machine. Authentication works fine in FireFox, Chrome and Safari but fails in IE8. If I circumvent the Proxy and access the application server directly then it works fine so it has something to do with proxy. There's nothing in the Event Viewer on any of the 3 machines to indicate what might be happening. If you connect using IE8 it prompts for your credentials instead of automatically passing them, yes I've setup an explicit trust over an above the domain trust, but it still errors out with a 401 error returned from the proxy. Any ideas where to start troubleshooting this?

• How do I get a remote tracking branch to stay up to date with remote origin in a bare Git repository?

  - by Beau Simensen

  I am trying to maintain a bare copy of a Git repository and having some issues keeping the remote tracking branches up to date. I create the remote tracking branches like this: git branch -t 0.1 origin/0.1 This seems to do what I need to do for that point in time. However, if I make changes to origin and then fetch with the bare repo, things start to fall apart. My workflow looks like this: git fetch origin It looks like all of the commits come in at that point, but my local copy of 0.1 is not being updated. I can see that the changes have been brought into the repository by doing the following: git diff 0.1 refs/remotes/origin/0.1 What do I need to do to get my tracking branch updated with the remote's updates? I feel like I must be missing a step or a flag somewhere.

• Converting BMPs to avi

  - by Lucas

  I want to convert folders with video-frames in bitmaps into avi or mpeg files. I already have a VBScript which does a lot of stuff on those files, so it would be neat to integrate a functionallity to convert those folders automatically from my script. I can only find solutions that seem pretty low level and unfortunatley I don't know a whole lot about video file formats. What is the easiest approach to achieve that without reinventing the wheel? My problem is that there is seem to be so much information that I am not sure where to start.

  I need to append/format a url with a list of ids for an api call however, when i put the list at the end of the api https://api.twitter.com/1.1/users/lookup.json?user_id=%s'%a i just get an empty string as a response. i have tried turning the list into a string and removing the square brackets doing a = str(followers['ids'])[1:-1] but i still get the same problem. and im assuming that its being caused by the single quote at the start. i have tried removing the apostrophe from the string doing a.replace("'", "") and now i have run out of ideas thanks

• How can I position QDockWidgets as the screen shot shows using code?

  - by Nathan

  I want a Qt window to come up with the following arrangement of dock widgets on the right. Qt allows you to provide an argument to the addDockWidget method of QMainWindow to specify the position (top, bottom, left or right) but apparently not how two QDockWidgets placed on the same side will be arranged. Here is the code that adds the dock widgets. this uses PyQt4 but it should be the same for Qt with C++ self.memUseGraph = mem_use_widget(self) self.memUseDock = QDockWidget("Memory Usage") self.memUseDock.setObjectName("Memory Usage") self.memUseDock.setWidget(self.memUseGraph) self.addDockWidget(Qt.DockWidgetArea(Qt.RightDockWidgetArea),self.memUseDock) self.diskUsageGraph = disk_usage_widget(self) self.diskUsageDock = QDockWidget("Disk Usage") self.diskUsageDock.setObjectName("Disk Usage") self.diskUsageDock.setWidget(self.diskUsageGraph) self.addDockWidget(Qt.DockWidgetArea(Qt.RightDockWidgetArea),self.diskUsageDock) When this code is used to add both of them to the right side, one is above the other, not like the screen shot I made. The way I made that shot was to drag them there with the mouse after starting the program, but I need it to start that way.

• Best method for Binding ComboBox

  - by LnDCobra

  I am going to be developing a large project which will include a large number of ComboBoxes. Most of these combo boxes will be bound to a database field which is a related to another daataset/table. For instance. I have the following 2 tables: Company {CompanyID, CompanyName, MainContact} Contacts {ContactID, ContactName} And when the user clicks to edit a company, A TextBox will be there to edit a company name, but also a ComboBox will be there. The way I am currently doing it is binding the ComboBox to the Contacts dataset, and manually updating the Company MainContact field in code behind. Is there anyway for me to bind the selected item to the Company MainContact field in XAML and the items to the ContactName and eliminate the code behind? Reason for this is when you start making 100's combo boxes all over the application it gets long winded each time creating code behind to do the update.

• IE8 + Jquery ajax call giving parsererror from dJango : for json data which seems valid in Firefox

  - by PlanetUnknown

  The ajax call works fine in FF. the data returned is in JSON here is an example from FF firebug - {"noProfiles": "No profiles have been created, lets start now !"} When I try to print the error in IE8 (& in compatibility modes as well), it says "parsererror". But the output seems to be valid JSON. Here is the ajax function call I'm making. Any pointers would be great ! $.ajax({ type: "GET", url: "/get_all_profile_details/", data: "", dataType: "json", beforeSend: function() {alert("before send called");}, success: function(jsonData) { alert("data received"); }, error: function(xhr, txt, err){ alert("xhr: " + xhr + "\n textStatus: " + txt + "\n errorThrown: " + err); } }); The alerts in the error function above give - xhr:<blank> textstatus:parsererror errorThrown: undefined Any pointers would be great ! Note : jquery : 1.3.2

• CakePHP HABTM Plugin table naming conventions (for 1.3)

  - by Parris

  Hi everyone, I know naming conventions for tables used by plugins generally start with the name of the plugin and then the model pluralized. For example lets say I had a plugin called Poll, with a model also called PollPoll and another model called PollTag then the resulting table names would be poll_polls and poll_tags. They would also have a habtm relationship so what is the convention for that table name? I believe it would poll_poll_polls_poll_tags, although it is a little redundant it makes sense since the first poll_ represents the name of the plugin, while poll_polls and poll_tags relates to the models. Also have any naming conventions changed for plugins in 1.3? Is the above stated correct? Thanks!

• How can unit testing make parameter validation redundant?

  - by Johann Gerell

  We have a convention to validate all parameters of constructors and public functions/methods. For mandatory parameters of reference type, we mainly check for non-null and that's the chief validation in constructors, where we set up mandatory dependencies of the type. The number one reason why we do this is to catch that error early and not get a null reference exception a few hours down the line without knowing where or when the faulty parameter was introduced. As we start transitioning to more and more TDD, some team members feel the validation is redundant. Uncle Bob, who is a vocal advocate of TDD, strongly advices against doing parameter validation. His main argument seems to be "I have a suite of unit tests that makes sure everything works". But I can for the life of it just not see in what way unit tests can prevent our developers from calling these methods with bad parameters in production code. Please, unit testers out there, if you could explain this to me in a rational way with concrete examples, I'd be more than happy to seize this parameter validation!

• Animated record deletion with jquery like mootools example

  I was reading around and saw this example from David Walsh about how to animate record deletion with mootools. Does the exact same effect exist in jquery? This is his mootools code. window.addEvent('domready',function() { $$('a.delete').each(function(el) { el.addEvent('click',function(e) { e.stop(); var parent = el.getParent('div'); var request = new Request({ url: 'mootools-record-delete.php', link: 'chain', method: 'get', data: { 'delete': parent.get('id').replace('record-',''), ajax: 1 }, onRequest: function() { new Fx.Tween(parent,{ duration:300 }).start('background-color', '#fb6c6c'); }, onSuccess: function() { new Fx.Slide(parent,{ duration:300, onComplete: function() { parent.dispose(); } }).slideOut(); } }).send(); }); }); });

• How to change the assemblyIdentity of a program

  - by David

  I want to hide the tool I used to create an .exe file. I am not doing anything illegal, I just want to protect my intellectual property from being copied. If I open the exe file in a text editor I see the following section. <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="XXX.XX" processorArchitecture="X86" name="Microsoft.Windows.NameOfTheTool" type="win32" /> </assembly> I have attempted to change the name to: name="Microsoft.Windows.SomeOtherName" This resulted in the following message when I attempted to execute the file. "This application has failed to start because its side-by-side configuration is incorrect." How can I solve this?

• Posting to tumblr in PHP

  - by Sherif

  I am trying to make a test post to my tumblr blog with a php script (that will eventually be ran as a cron job) I have been browsing google and read many answers on here and the closest I found is explained in this post: Tumblr OAuth using PHP's OAuth class I am using the code in his tutorial here: http://vigrond.com/blog/2012/02/04/oauth-extension-php-and-the-tumblr-api/ Pretty much as is, replacing the blogurl with mine and of course the consumer and secret key. When I run the .php script via my browser however, nothing happens. Any ideas? EDIT: The only error I found in cPanel's error log is this: [Wed Oct 31 00:29:25 2012] [error] [client xx.xx.xx.xx ] PHP Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /path on line 14 But I fixed this and the error does not appear anymore.

• Using CreateFileMapping between to programs - C

  - by Jamie Keeling

  Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.
