  • Rails: How to test state_machine?

    - by petRUShka
    Please, help me. I'm confused. I know how to write state-driven behavior of model, but I don't know what should I write in specs... My model.rb file look class Ratification < ActiveRecord::Base belongs_to :user attr_protected :status_events state_machine :status, :initial => :boss do state :boss state :owner state :declarant state :done event :approve do transition :boss => :owner, :owner => :done end event :divert do transition [:boss, :owner] => :declarant end event :repeat do transition :declarant => :boss end end end I use state_machine gem. Please, show me the course.

  • Why is an inverse loop faster than a normal loop (test included)

    - by Saif Bechan
    I have been running some small tests in PHP on loops. I do not know if my method is good. I have found that a inverse loop is faster than a normal loop. I have also found that a while-loop is faster than a for-loop. Setup <?php $counter = 10000000; $w=0;$x=0;$y=0;$z=0; $wstart=0;$xstart=0;$ystart=0;$zstart=0; $wend=0;$xend=0;$yend=0;$zend=0; $wstart = microtime(true); for($w=0; $w<$counter; $w++){ echo ''; } $wend = microtime(true); echo "normal for: " . ($wend - $wstart) . "<br />"; $xstart = microtime(true); for($x=$counter; $x>0; $x--){ echo ''; } $xend = microtime(true); echo "inverse for: " . ($xend - $xstart) . "<br />"; echo "<hr> normal - inverse: " . (($wend - $wstart) - ($xend - $xstart)) . "<hr>"; $ystart = microtime(true); $y=0; while($y<$counter){ echo ''; $y++; } $yend = microtime(true); echo "normal while: " . ($yend - $ystart) . "<br />"; $zstart = microtime(true); $z=$counter; while($z>0){ echo ''; $z--; } $zend = microtime(true); echo "inverse while: " . ($zend - $zstart) . "<br />"; echo "<hr> normal - inverse: " . (($yend - $ystart) - ($zend - $zstart)) . "<hr>"; echo "<hr> inverse for - inverse while: " . (($xend - $xstart) - ($zend - $zstart)) . "<hr>"; ?> Average Results The difference in for-loop normal for: 1.0908501148224 inverse for: 1.0212800502777 normal - inverse: 0.069570064544678 The difference in while-loop normal while: 1.0395669937134 inverse while: 0.99321985244751 normal - inverse: 0.046347141265869 The difference in for-loop and while-loop inverse for - inverse while: 0.0280601978302 Questions My question is can someone explain these differences in results? And is my method of benchmarking been correct?

  • sync framework server to server synchronization

    - by nihi_l_ist
    I have kind of a such scenario: Here i need to synchronize local server database with main DB server(example: computers in office are connected to office server and they use it like a local server, so that no sync is required.BUT computers in other office work with their local server too and we need synchronization between the offices though the main DB server.). As i see i cant use SQLCompact here. Is there a provider to do the server-to-server synchronization right from the client? If no can someone provide a sample of solution of how to manage such situation?

  • Is there a way to prevent Maven Test from rebuilding the database?

    - by Christopher W. Allen-Poole
    I've recently been asked to, effectively, sell my department on unit testing. I can't tell you how excited this makes me, but I do have one concern. We're using JUnit with Spring and Maven, and this means that each time mvn test is called, it rebuilds the database. Obviously, we can't integrate that with our production server -- it would kill valuable data. How do I prevent the rebuilding without telling maven to skip testing? The best I could figure was to assign the script to operate in a test database (line breaks added for readability): mvn test -Ddbunit.schema=<database>test -Djdbc.url=jdbc:mysql://localhost/<database>test? createDatabaseIfNotExist=true&amp; useUnicode=true&amp;characterEncoding=utf-8 I can't help but think there must be a better way. I'm especially interested in learning if there is an easy way to tell Maven to only run tests on particular classes without building anything else? mvn -Dtest=<test-name> test still rebuilds the database. ======= update ======= Bit of egg on my face here. I didn't realize that I was using the same variable in two places, meaning that the POM was using a "skip.test" variable for both rebuilding the database and for running the tests...

  • Suspend file validation on Zend Framework

    - by dimitris mistriotis
    Hi, Currently on my application I have a form where I ask the user to upload an image file to be used as a logo. I want to allow the user to reset that to nothing by supplying no file (by just pressing the upload button from the browser). In this scenario the only thing left is to suspend file validation when no file is included. Currently I get the *self::NO_FILE* error from the *Zend_Validate_File_Upload* class. Is there any way to suspend the validation so that nothing will be checked if no file has been provided?

  • Trouble installing Rhodes framework

  • How to configure the framesize using AudioUnit.framework on iOS

    - by Piperoman
    I have an audio app i need to capture mic samples to encode into mp3 with ffmpeg First configure the audio: /** * We need to specifie our format on which we want to work. * We use Linear PCM cause its uncompressed and we work on raw data. * for more informations check. * * We want 16 bits, 2 bytes (short bytes) per packet/frames at 8khz */ AudioStreamBasicDescription audioFormat; audioFormat.mSampleRate = SAMPLE_RATE; audioFormat.mFormatID = kAudioFormatLinearPCM; audioFormat.mFormatFlags = kAudioFormatFlagIsPacked | kAudioFormatFlagIsSignedInteger; audioFormat.mFramesPerPacket = 1; audioFormat.mChannelsPerFrame = 1; audioFormat.mBitsPerChannel = audioFormat.mChannelsPerFrame*sizeof(SInt16)*8; audioFormat.mBytesPerPacket = audioFormat.mChannelsPerFrame*sizeof(SInt16); audioFormat.mBytesPerFrame = audioFormat.mChannelsPerFrame*sizeof(SInt16); The recording callback is: static OSStatus recordingCallback(void *inRefCon, AudioUnitRenderActionFlags *ioActionFlags, const AudioTimeStamp *inTimeStamp, UInt32 inBusNumber, UInt32 inNumberFrames, AudioBufferList *ioData) { NSLog(@"Log record: %lu", inBusNumber); NSLog(@"Log record: %lu", inNumberFrames); NSLog(@"Log record: %lu", (UInt32)inTimeStamp); // the data gets rendered here AudioBuffer buffer; // a variable where we check the status OSStatus status; /** This is the reference to the object who owns the callback. */ AudioProcessor *audioProcessor = (__bridge AudioProcessor*) inRefCon; /** on this point we define the number of channels, which is mono for the iphone. the number of frames is usally 512 or 1024. */ buffer.mDataByteSize = inNumberFrames * sizeof(SInt16); // sample size buffer.mNumberChannels = 1; // one channel buffer.mData = malloc( inNumberFrames * sizeof(SInt16) ); // buffer size // we put our buffer into a bufferlist array for rendering AudioBufferList bufferList; bufferList.mNumberBuffers = 1; bufferList.mBuffers[0] = buffer; // render input and check for error status = AudioUnitRender([audioProcessor audioUnit], ioActionFlags, inTimeStamp, inBusNumber, inNumberFrames, &bufferList); [audioProcessor hasError:status:__FILE__:__LINE__]; // process the bufferlist in the audio processor [audioProcessor processBuffer:&bufferList]; // clean up the buffer free(bufferList.mBuffers[0].mData); //NSLog(@"RECORD"); return noErr; } With data: inBusNumber = 1 inNumberFrames = 1024 inTimeStamp = 80444304 // All the time same inTimeStamp, this is strange However, the framesize that i need to encode mp3 is 1152. How can i configure it? If i do buffering, that implies a delay, but i would like to avoid this because is a real time app. If i use this configuration, each buffer i get trash trailing samples, 1152 - 1024 = 128 bad samples. All samples are SInt16.

  • "Failed to find or load the registered .Net Framework Data Provider" with MySQL + ASP.NET

    - by Malachi
    How do we repair this? This question has been sort of addressed many times around the internet, but it's always a workaround. Always copying the MySql.data.dll into your bin directory, or explicitly stating what version you want. What is the "proper" approach to using DbProvderFactory for MySQL with ASP.NET? I'd like to be able to develop locally and not worry what version they have installed on the server. As it stands, if I do copy up my own version I have to make sure it's the one they use. Seems easy to break.

  • Using ScriptingBridge framework for communicating with Entourage

    - by Subramanian Ganapathy
    Hi, The motivation for my question is the following doc, which describes how mail.app could be integrated using ScriptingBridge: http://developer.apple.com/mac/library/samplecode/SBSendEmail/Introduction/Intro.html I tried to apply a similar technique with Entourage as well but could not get any results so far. I understand that using AppleScript would help me solve my problem and mactech.com has extensive documentation for doing so. But i find this ScriptingBridge technique elegant and want to figure why it is not working for me with Entourage. The biggest problem seems to be my inability to create Scripting classes based on their names as it happens in Mail because Entourage has a different interface than Mail as their headers indicate. Could someone please tell me what I am missing or provide any sort of hint on why this wont work? I am also adding sample code ` MicrosoftEntourageApplication * mail = [SBApplication applicationWithBundleIdentifier:@"com.Microsoft.Entourage"]; MicrosoftEntourageOutgoingEmailMessage * emailMessage = [[[mail classForScriptingClass:@"outgoing message"] alloc] initWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: @"my sample subject", @"subject", @"my sample body", @"content", nil]]; //then i create a set of recipients and try to use "to recipient" as the string scripting class id, but MicrosoftEntourageRecipient is returned as nil MicrosoftEntourageRecipient * theRecipient = [[[mail classForScriptingClass:@"to recipient"] alloc] initWithProperties: [NSDictionary dictionaryWithObjectsAndKeys: @"[email protected]", @"address", nil]]; ` I am trying to make the simple thing work, I am not even concentrating on the task I am supposed to do now. I am a Cocoa beginner( and willing to learn ), please excuse an syntactic naivetes and do point them out in the sample code, in addition to answering my question. Best Regards, Subramanian

  • Softrware Licensing / Registration component/framework?

    - by Clay Nichols
    We use a home-grown Registration System for our software but I'd like to update it fixing a number of things including adding the ability to remotely activate/deactivate it (to facilitate Saas). Feel free to suggest any good (in your opinion) VB6- compatible option. I can check out whether it meets our other criteria below. Required Features: Activate multiple programs (Ok if it generates a separate code for each one) Works with VB6 and VB.net. A VB6-compatible DLL should be fine. Still supported (nice to have but not absolutely required Compatible with Windows 2000 through 7. Nice-to-have features (but not required) * Work without internet access * Works through a firewall (this may be a tough one) Any suggestions?

  • Test if single linked list is circular by traversing it only once

    - by user1589754
    I am a fresher and I was asked this question in a recent interview I gave. The question was --- By traversing each element of linked list just once find if the single linked list is circular at any point. To this I answered that we will store reference of each node while traversing the list in another linked list and for every node in the list being tested we will find if the reference exists in the list I am storing the references. The interviewer said that he needs a more optimized way to solve this problem. Can anyone please tell me what would be a more optimized method to solve this problem.

  • What is the correct way to unit test areas around exceptions

    - by Codek
    Hi, Looking at our code coverage of our unit tests we're quite high. But the last few % is tricky because a lot of them are catching things like database exceptions - which in normal circumstances just dont happen. For example the code prevents fields being too long etc, so the only possible database exceptions are if the DB is broken/down, or if the schema is changed under our feet. So is the only way to Mock the objects such that the exception can be thrown? That seems a little bit pointless. Perhaps it's better to just accept not getting 100% code coverage? Thanks, Dan

  • Ajax Rich Internet Application framework for Linux + Firefox _AND_ iPhone consumption

    - by Maroloccio
    For a zero-budget (e.g. University) project we need to build a rich web UI for Firefox and iPhone clients. Firm requirement: all technologies to be free and open-source. Nice-to-have: all development to be done in Java/Eclipse. I generally like the Google's AppEngine + GWT combo but this project will require much more interactivity than what's in GWT 2.0. Something along the lines of: http://www.smartclient.com/smartgwt/showcase/. I know trusty plain ol' GWT won't cut it this time. Straight question: is there something that does the sort of thing that SmartGWT does and works really well on Safari/iPhone? I would say the mobile experience is even more important for this project than the desktop one. Optional question: perhaps this is not the best route to go at all? How could we otherwise render a rich UI with such capabilities and interactivity on both screen sizes? Windows, drag-and-drop, advanced tabs, dynamic grids... We don't need to support any other mobile devices. Yet. ;-)

  • Overloading framework methods in objective-c, or retaining local changes with framework updates.

    - by Jeff B
    I am using cocos2d to build an iPhone game. It's mostly done, but along the way I came across some things that I would like to handle better. I am fairly new to Objective C, and honestly I do more Perl scripting in my day-to-day job than anything, so my C skills are a little rusty. One of them is the fact that I have modified cocos2d files for some specific cases in my game. However, when I update to a new version, I have to manually pull my changes forward. So, the question is, what is the best way to deal with this? Some options I have thought of: Overload/redefine the cocos2d classes. I was under the impression that I cannot overload existing class functions, so I don't think this will work. Create patches that I re-apply after library updates. I don't think this will work as the new files won't necessarily be the same as the old ones, and if they were, I could just copy the whole file forward. Turn in my changes to Cocos2d. Not an option as my changes are very specific to my application. Am I missing something obvious? UPDATE: I will explain what I am doing to be more clear. Cocos2d has a CCNode object, which can contain children, etc. I added a shadow, which is very similar to a child, but handled a little differently. The shadow has an offset from the parent, and translates with it's parent, rotates around it's own center when the parent rotates, etc. The shadow is not included as a true child, however, so given the correct z-index, the shadows can render under ALL other objects, but still move with the parent. To do this I added addShadow functions to CCNode, and modified the setPosition and setRotate functions to move the shadowSprite: CCNode.m: -(id) init { if ((self=[super init]) ) { ... shadowSprite_ = nil; ... } } ... -(BOOL) addShadow: (CCNode*) child offset: (CGPoint) offset { shadowSprite_ = child; shadowSprite_.position = CGPointMake(position_.x+offset.x, position_.y+offset.y); return YES; } ... -(void) setRotation: (float)newRotation { rotation_ = newRotation; isTransformDirty_ = isInverseDirty_ = YES; if(shadowSprite_) { [shadowSprite_ setRotation: newRotation]; } } There is more, of course, including the prototypes in the .h file, but that is the basics. I don't think I need shadowSprite to be a property, because I don't need to access it after it has been added.

  • A web framework where AJAX was not an after thought

    - by Pirate for Profit
    AJAX is a pain in the ass because it essentially means you'll have to write two sets of similarish code: one for browsers with JavaScript enabled and those without. Not only this, but you have to connect JavaScript events to hook into your models and display the results. And if all that weren't bad enough, you need to send an address change with the request, otherwise the user won't be able to "click back" correctly (if confused look at what happens to the address bar when you click links in GMail). We're searching for something that had the foresight and design goals with all these concerns in mind. Performance and security are also obvious major concerns. We love config-based systems as well, where you don't have to write a lot of code you just drop it into an easily read config format. It's like asking for the holy grail right?

  • Test For CSS3 Radial Gradient Vendor Syntax

    - by Scott Christopherson
    I'm having an issue where I'm trying to update the background gradient of an element with JavaScript based on values I specify. I tried this route: elem.style.backgroundImage = '-webkit-gradient(radial, '+x+' '+y+', 0, '+x+' '+y+', 800, from(#ccc), to(#333)), -moz-radial-gradient('+x+'px '+y+'px, circle cover, #ccc 0, #333 100%)'; Since Webkit and Gecko have two different syntaxes for CSS3 gradients, I need to specify both. However, the above code doesn't work. It works if I only have just the Gecko syntax or just the Webkit syntax, not both. I think you can check for CSS gradient support, but my question is, is there a way to check which syntax needs to be used without browser sniffing? Keep in mind that I need to set my gradients this way since the x and y coordinates of the gradient change dynamically. Hope this makes sense, thanks.
