  • Emacs VCS interface commits only one file

    - by myfreeweb
    When I commit changes with Emacs' built-in VCS interface (I use it with Bazaar) it commits only one file - that's open in current buffer. So when I press C-c v v, enter message and C-c C-c, it does something like bzr commit -m "my message" file/open/in.buffer instead of bzr commit -m "my message" How to commit all changes with Emacs?

  • Accessing underlying managed object through a COM interface

    - by mfeingold
    I have a third party assembly with a public abstract class implementing a certain COM interface. Something to the effect of [ComVisible(true)] public abstract class SomeClass: ISomeInterface { .... public void Method1() {...} } The actual object is an internal object extending the SomeClass and is instantiated by the third party code Is there a way to access public methods of this class if all I have is the CCW to the ISomeInterface?

  • Use web interface to modify htaccess file

    - by justinl
    The solution to a previous question (How to implement “Maintenance Mode” on already established website), was to use a modified .htaccess to deny IP addresses. What is the best way to use a web interface to modify an .htaccess file? What I want is a way for an admin to log in to the admin area and switch Maintenance Mode on and off using a basic html form. I'm using PHP and I'm already using an .htaccess file for a handful of ReWriting.

  • Novocaine - How to loop file playback? (iOS)

    - by lppier
    I'm using Novocaine by alexbw Novocaine for my audio project. I'm playing around with the example code here for file reading. The file plays back with no problem. I would like to loop this recording with the gap between the loops - any suggestion as to how I can do so? Thanks. Pier. // AUDIO FILE READING OHHH YEAHHHH // ======================================== NSArray *pathComponents = [NSArray arrayWithObjects: [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], @"testrecording.wav", nil]; NSURL *inputFileURL = [NSURL fileURLWithPathComponents:pathComponents]; NSLog(@"URL: %@", inputFileURL); fileReader = [[AudioFileReader alloc] initWithAudioFileURL:inputFileURL samplingRate:audioManager.samplingRate numChannels:audioManager.numOutputChannels]; [fileReader play]; [fileReader setCurrentTime:0.0]; //float duration = fileReader.getDuration; [audioManager setOutputBlock:^(float *data, UInt32 numFrames, UInt32 numChannels) { [fileReader retrieveFreshAudio:data numFrames:numFrames numChannels:numChannels]; NSLog(@"Time: %f", [fileReader getCurrentTime]); }];

  • How Do I Convert text to a WAV file With Inaudible Waveform?

    - by Scott
    I am trying to create an audio watermarking system. I figure the best solution is to create an audio file (WAV) based on a unique string of text and then combine this with the original wav. The part that makes this tricky (for me anyway) is: How do I convert the text string to a wav? How do I ensure that the resulting WAV form is inaudible (or at least barely noticeable to the listener). I would prefer this be done server side (via PHP, etc) but if the processing load isn't too much then would be ok with something in Flash or Javascript. I'd be willing to pay someone to create me a workable solution (complete source code that functions as described). Thanks, Scott!

  • Problem in implementing IAlertUpdateHandler interface

    - by TheVillageIdiot
    I've implemented IAlertUpdateHandler interface in a class and used it for handling creation and updating of alerts. The code is fired but it goes into endless loop by calling itself again and again. Actually I want to suppress email notification so I'm calling a.Update(false); but this again calls PreUpdate or PostUpdate method and there is StackOverFlowException :( I've tried returning true/false from both the methods but nothing is helping.

  • Job queue manager with RPC interface

    - by admr
    I need a job queue manager that I can control over the Internet. It should be able to execute and stop processes, check on their status (ideally notice and execute some code when a process exits), respond to commands and also be able to report back to a server. Background: I have a GWT application that allows to create jobs to execute on a cloud instance (currently EC2). I want to push a "job packet" (data for a process to operate on etc) to S3, start a Linux EC2 instance (or use one that's already running), and tell a job manager on the instance to execute that job (possibly parallel to other jobs). It should then pull the "job packet" from S3, run a process that operates on that data and report back to the server that is running the server part of my GWT application with some information (e.g. exit code, stdout, stderr). If I have to write e.g. stdour/err to a file from the process and read that file, that's OK too. I would really like the manager to be "close" to the processes it runs, meaning I want to avoid using something like Runtime.exec from the JDK. It seems like I would have to do that if I used Quartz for example. I'm fine with the calls in both directions being asynchronous. I'm fine with any reasonable technology for the calls as long as I can easily build an interface for that in my GWT server side (e.g. HTTP requests to a servlet over SSL would be nice and trivial). The job manager does not need to have a very sophisticated queueing system. Running several processes either sequentially or in parallel should be fine. Determining how much compute time a process received during its lifetime would be nice (AFAIK, this might be challenging). I did not yet find any existing software that does this, including http://java-source.net/open-source/job-schedulers. I suspect I might have to build an RPC interface (with authentication etc, of course) around a job manager; maybe use something like Apache Commons Exec. In that case, I would prefer Java or Python for the job manager part. I would be happy to hear suggestions for either the former or latter scenario!

  • 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.

  • Prefered method for looping sound flash as3

    - by Brian Heylin
    Hi there, I'm having some issues with looping a sound in flash AS3, in that when I tell the sound to loop I get a slight delay at the end/beginning of the audio. The audio is clipped correctly and will play without a gap on garage band. I know that there are issues with sound in general in flash, bugs with encodings and the inaccuracies with the SOUND_COMPLETE event (And Adobe should be embarrassed with their handling of these issues) I have tried to use the built in loop argument in the play method on the Sound class and also react on the SOUND_COMPLETE event, but both cause a delay. But has anyone come up with a technique for looping a sound without any noticeable gap?

  • Recommendations for a C++ polymorphic, seekable, binary I/O interface

    - by Trevor Robinson
    I've been using std::istream and ostream as a polymorphic interface for random-access binary I/O in C++, but it seems suboptimal in numerous ways: 64-bit seeks are non-portable and error-prone due to streampos/streamoff limitations; currently using boost/iostreams/positioning.hpp as a workaround, but it requires vigilance Missing operations such as truncating or extending a file (ala POSIX ftruncate) Inconsistency between concrete implementations; e.g. stringstream has independent get/put positions whereas filestream does not Inconsistency between platform implementations; e.g. behavior of seeking pass the end of a file or usage of failbit/badbit on errors Don't need all the formatting facilities of stream or possibly even the buffering of streambuf streambuf error reporting (i.e. exceptions vs. returning an error indicator) is supposedly implementation-dependent in practice I like the simplified interface provided by the Boost.Iostreams Device concept, but it's provided as function templates rather than a polymorphic class. (There is a device class, but it's not polymorphic and is just an implementation helper class not necessarily used by the supplied device implementations.) I'm primarily using large disk files, but I really want polymorphism so I can easily substitute alternate implementations (e.g. use stringstream instead of fstream for unit tests) without all the complexity and compile-time coupling of deep template instantiation. Does anyone have any recommendations of a standard approach to this? It seems like a common situation, so I don't want to invent my own interfaces unnecessarily. As an example, something like java.nio.FileChannel seems ideal. My best solution so far is to put a thin polymorphic layer on top of Boost.Iostreams devices. For example: class my_istream { public: virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) = 0; virtual std::streamsize read(char* s, std::streamsize n) = 0; virtual void close() = 0; }; template <class T> class boost_istream : public my_istream { public: boost_istream(const T& device) : m_device(device) { } virtual std::streampos seek(stream_offset off, std::ios_base::seekdir way) { return boost::iostreams::seek(m_device, off, way); } virtual std::streamsize read(char* s, std::streamsize n) { return boost::iostreams::read(m_device, s, n); } virtual void close() { boost::iostreams::close(m_device); } private: T m_device; };

  • Signal amplitude against time in Java

    - by wsr74ws84
    I'm racking my brain in order to solve a knotty problem (at least for me). While playing an audio file (using Java) I want the signal amplitude to be displayed against time. I mean I'd like to implement a small panel showing a sort of oscilloscope (spectrum analyzer). The audio signal should be viewed in the time domain (vertical axis is amplitude and the horizontal axis is time). Does anyone know how to do it? Is there a good tutorial I can rely on? Since I know very little about Java, I hope someone can help me.

  • iPhone Human Interface Guidelines question

    - by Kyle
    iPhone Human Interface Guidelines -- Do they apply for OpenGL games? GL games typically have custom buttons, custom lists, etc. Take the Quake player list for example, if ported, it wouldnt be a typical UI list object. Does this mean the reviewer in question would reject anything that wasn't using standard UI? Or, is there an exception for games.

  • How to make a simple grafical interface in C# for DCRAW

    - by Espinas.iss
    Hello, i have a problem. I need to make a simple GUI in Visual Studio 2008 using C Sharp that uses a Dave Coffins DCRAW written in C but I don't know how to "connect" dcraw.c (DCRAW source code) file with Csharp... UFRAW is the example of grafical interface that uses dcraw but I can't find it's source code. My application should be very simple: to recognize raw file on digital camera or any disc and uses one interpolatio algorithm on that raw file.

  • SWI-Prolog Semantic Web Library and Python Interface

    - by John Peter Thompson Garcés
    I want to write a Python web application that queries RDF triples using Prolog. I found pyswip for interfacing Python with SWI-Prolog, and I am currently looking into SWI-Prolog's RDF capabilities. I am wondering if anyone has tried this before--and if anyone has: what did your setup look like? How do you get pyswip to work with the SWI-Prolog semantic web library? Or is there another Python-Prolog interface that makes this easier?

  • Accessing a web service and a HTTP interface using certificate authentication

    - by ADC
    It is the first time I have to use certificate authentication. A commercial partner expose two services, a XML Web Service and a HTTP service. I have to access both of them with .NET clients. What I have tried 0. Setting up the environment I have installed the SSLCACertificates (on root and two intermediate) and the client certificate in my local machine (win 7 professional) using certmgr.exe. 1. For the web service I have the client certificate (der). The service will be consumed via a .NET proxy. Here's the code: OrderWSService proxy = new OrderWSService(); string CertFile = "ClientCert_DER.cer"; proxy.ClientCertificates.Add(new System.Security.Cryptography.X509Certificates.X509Certificate(CertFile)); orderTrackingTO ot = new orderTrackingTO() { order_id = "80", tracking_id = "82", status = stateOrderType.IN_PREPARATION }; resultResponseTO res = proxy.insertOrderTracking(ot); Exception reported at last statement: The request failed with an empty response. 2. For the HTTP interface it is a HTTPS interface I have to call through POST method. The HTTPS request will be send from a .NET client using HTTPWebRequest. Here's the code: string PostData = "MyPostData"; //setting the request HttpWebRequest req; req = (HttpWebRequest)HttpWebRequest.Create(url); req.UserAgent = "MyUserAgent"; req.Method = "POST"; req.ContentType = "application/x-www-form-urlencoded"; req.ClientCertificates.Add(new System.Security.Cryptography.X509Certificates.X509Certificate(CertFile, "MyPassword")); //setting the request content byte[] byteArray = Encoding.UTF8.GetBytes(PostData); Stream dataStream = req.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); //obtaining the response WebResponse res = req.GetResponse(); r = new StreamReader(res.GetResponseStream()); Exception reported at last statement: The request was aborted: Could not create SSL/TLS secure channel. 3. Last try: using the browser In Chrome, after installing the certificates, if I try to access both urls I get a 107 error: Error 107 (net::ERR_SSL_PROTOCOL_ERROR) I am stuck.

  • Html5 - Callback when media is ready on iPad wont work

    - by Kap
    I'm trying to add a callback to a HTML5 audio element on an iPad. I added an eventlistener to the element, the myOtherThing() starts but there is no sound. If I pause and the play the sound again the audio starts. This works in chrome. Does anyone have an idea how I can do this? myAudioElement.src = "path_to_file"; addEventListener("canplay", function(){ myAudioElement.play(); myOtherThing.start(); }); SOLVED Just wanted to share my solution here, just in case someone else needs it. As far as I understand the iPad does not trigger any events without user interactions. So to be able to use "canply", "playing" and all the other events you need to use the built in media controller. Once you press play in that controller, the events gets triggered. After that you can use your custom interface.
