  • OpenAL device, buffer and context relationship

    - by Markus
    I'm trying to create an object oriented model to wrap OpenAL and have a little problem understanding the devices, buffers and contexts. From what I can see in the Programmer's Guide, there are multiple devices, each of which can have multiple contexts as well as multiple buffers. Each context has a listener, and the alListener*() functions all operate on the listener of the active context. (Meaning that I have to make another context active first if I wanted to change it's listener, if I got that right.) So far, so good. What irritates me though is that I need to pass a device to the alcCreateContext() function, but none to alGenBuffers(). How does this work then? When I open multiple devices, on which device are the buffers created? Are the buffers shared between all devices? What happens to the buffers if I close all open devices? (Or is there something I missed?)

  • Singelton on iPhone Simulator vs Singelton on real Device

    - by Helge Becker
    I am using a Singelton for some shared stuff. In the simulator, the app crashes ocasionally. Tracking the crash down shows that the the properties of my Singelton became dealocated. Those crashes never happend on a real device. Does the iPHone simulator handle memory managemend different? GC maybe? Changed the singelton to match this pattern. The iPhone Simulator dont crash now, but I am not sure about the memory handling on the real device. I assume that this solution will cause problems. What do you think?

  • Android strace in Real device

    - by Martin Solac
    I have the following situation, I want to monitor the system calls on Android phones so I made an script to do that. With Android Emulator works perfectly (writes the traces of the application in a specific file on my Ubuntu). The problem is when I attach a real phone to analyze it, it says the following in the result file: ptrace attach failed: Operation not permitted I'm using this code to get it, but I don't understand why it works on the emulator and not in the rooted real device. This is the comand I use in perl: system("$dirTools/adb -s $Device shell strace -p $PID[1]>$dirRecordDataSet/$Date/$appName &"); Any suggestion? Thanks in advance

  • How to receive a datastream from a device on your computer, in C#

    - by WebDevHobo
    I plan to build a small audio-recorder app in C#. My laptop has a built in Microphone that's always active, so I want to use that as an early-stage test. I would simply start recording, save the file as a .wav or even use the LAME dll to make it into an MP3. The problem is, I don't know how to contact that microphone. Do I use a library that can detect a device, or do I just catch a stream of bytes from the port that the device is on? I don't have any experience with receiving data from connected devices. I suppose that I'll need to enter all the data into a byte array and then Serialize that into a WAV file, but I'm not sure. Can I get some pointers on this subject?

  • mobile device - different background - media query not working

    - by AMC
    Live site. This is my first attempt at utilizing a different CSS for mobile devices vs. regular screens. To do this, I'm using- @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { background: url('img/background.jpg') no-repeat center center fixed; background-size: cover; height: 100%; } However, it doesn't seem to be working (I can only test on iPhones). Any ideas as to why that may be? I've also tried @media all to no avail.

  • Make a USB Device, Control It In Java

    - by yar
    I'm thinking about making a physical controller (device?) with knobs, buttons, and LEDs. I'd like to interact with it using Java (respond to the knobs, light up LEDs, etc). The reason I mention Java is two-fold: first, I know Java well1. Second, I've written the rest of the program I need to interface with in Java (though there are ways to talk to the Java program from another language). I would like the device to connect via USB and be (computer-)platform independent. I haven't the slightest idea of where to start, except to start reading the Arduino website. Is this my best/only option? Is there something better suited for communicating with Java? Note: I know that Arduino has something to do with Java (not sure what), but it seems like code must be written in a subset of C. How would I get moving on this topic? 1 - No laughter, please.

  • timing response speed of serial device

    - by dario frongi
    I comunicate with a serial device via bluetooth. i send it pid and it responds to me with a data response. i comunicate with him with serial comunicatione one request-response. i want to measure how many response i receive in one second. i think that i have to know the moment when i do the request and the moment whene i receive the response and do the difference. The result(called delta) is the time-to response of device. in the end i have to do 1000ms/delta. how can calculate it ?

  • How to copy the memeory allocated in device function back to main memory

    - by xhe8
    I have a CUDA program containing a host function and a device function Execute(). In the host function, I allocate a global memory output which will then be passed to the device function and used to store the address of the global memory allocated within the device function. I want to access the in-kernel allocated memory in the host function. The following is the code: #include <stdio.h> typedef struct { int * p; int num; } Structure_A; \__global__ void Execute(Structure_A *output); int main(){ Structure_A *output; cudaMalloc((void***)&output,sizeof(Structure_A)*1); dim3 dimBlockExecute(1,1); dim3 dimGridExecute(1,1); Execute<<<dimGridExecute,dimBlockExecute>>>(output); Structure_A * output_cpu; int * p_cpu; cudaError_t err; output_cpu= (Structure_A*)malloc(1); err=cudaMemcpy(output_cpu,output,sizeof(Structure_A),cudaMemcpyDeviceToHost); if( err != cudaSuccess) { printf("CUDA error a: %s\n", cudaGetErrorString(err)); exit(-1); } p_cpu=(int *)malloc(1); err=cudaMemcpy(p_cpu,output_cpu[0].p,sizeof(int),cudaMemcpyDeviceToHost); if( err != cudaSuccess) { printf("CUDA error b: %s\n", cudaGetErrorString(err)); exit(-1); } printf("output=(%d,%d)\n",output_cpu[0].num,p_cpu[0]); return 0; } \__global__ void Execute(Structure_A *output){ int thid=threadIdx.x; output[thid].p= (int*)malloc(thid+1); output[thid].num=(thid+1); output[thid].p[0]=5; } I can compile the program. But when I run it, I got a error showing that there is a invalid argument in the following memory copy function. "err=cudaMemcpy(p_cpu,output_cpu[0].p,sizeof(int),cudaMemcpyDeviceToHost);" CUDA version is 4.2. CUDA card: Tesla C2075 OS: x86_64 GNU/Linux

  • jQuery center multiple dynamic images in different sized containers

    - by JVK Design
    So I've found similar questions but none that answer all the questions I have and I know there must be a simple jQuery answer to this. I've got multiple images that are being dynamically placed in their own containing div that have overflow:hidden, they need to fill their containing divs and be centered(horizontally and vertically) also. The containing divs will be different sizes as well. So in short: multiple different sized images fill and center in containing div. containing divs will be different sizes. will be used multiple times on a page. Hopefully this image helps explain what I'm after. Click here to view the image. HTML I'm using but can be changed <div class="imageHolder"> <div class="first SlideImage"> <img src="..." alt="..."/> </div> <div class="second SlideImage"> <img src="..." alt="..."/> </div> <div class="third SlideImage"> <img src="..." alt="..."/> </div> </div> And the CSS .imageHandler{ float:left; width:764px; height:70px; margin:1px 0px 0px; } .imageHolder .SlideImage{ float:left; position:relative; overflow:hidden; } .imageHolder .SlideImage img{ position:absolute; } .imageHolder .first.SlideImage{ width:381px; height:339px; margin-right:1px; } .imageHolder .second.SlideImage{margin-bottom:1px;} .imageHolder .second.SlideImage, .imageHolder .third.SlideImage { width: 382px; height: 169px; } Ask me anything if this doesn't make sense, thanks in advance

  • Rotate rectangle around center

    - by ESoft
    I am playing with Brad Larsen's adaption of the trackball app. I have two views at a 60 degree angle to each other and was wondering how I get the rotation to be in the center of this (non-closed) rectangle?

  • How can i get latency when using Game Center?

    - by Freddy
    I'm pretty new to network programming. Basically I'm using game center for making a relatively simple iPhone game using Game-center p2p. However i'm now working on a algorithm to improve the multiplayer performance. But, I need to know how long it took for a package to travel from one device to the another device (latency) for the algorithm to work good. As for now, I have solved the problem by sending a double with time interval since 1970 in the package and then I compare it with the time at the other device. However I have heard that the NSDate methods is connected to the internet, which also will cause latency so the time interval would not be perfectly correct. What is the ideal way to check for how long it take for a package to be sent?

    Possible Duplicate: Dropbox fails to install, stuck at 99% I just installed Dropbox via Ubuntu Software Center, and the known crash of 99%, which was in Ubuntu Software center, happened. I want to remove Dropbox completely since something went wrong, but I can't. When I start my Ubuntu, it starts a process which eats up all of the CPU. In Ubuntu Software Center, there is a process "Searching Applying Changes", but nothing really happens. When I'm trying to uninstall Dropbox, nothing happens, since the seaching thing is "first". Please, I'm asking for a option which doesn't include proper reinstallation of Dropbox, only of getting rid of it, and without reinstalling the whole Ubuntu system (format, chaos etc).

    Not sure how specifically to word this... I'm wondering if there's any way to take a video stream from one application, for example VLC Media Player, and present that video stream to other applications as a video input source. For example, could I broadcast a video file from my hard disk to a website that allows video conferencing using a Flash applet? Basically, I'm looking for something like Soundflower, but for video streams. Is this possible? Tags, title, question re-wording suggestions welcomed -- I'm not sure how to properly describe this.

  • Install a web certificate on an Android device

    - by martani_net
    To gain access to WIFI at university I have to login with my user/pass credentials. The certificate of their website (the local home page that asks for the credentials) is not recognized as a trusted certificate, so we install it separately on our computers. The problem is that I don't take my laptop with me often to university, so I usually want to connect using my HTC Magic, but I have no clue on how to install the certificate separately on Android, it is always rejected. [Edit2] : this is what is stated in their website Need for installation of official certificates CyberTrust validated by the CRU (http://www.cru.fr/wiki/scs/) The certificates contain information certified to generate encryption keys for data exchange, called "sensitive" as the password of a user. By connecting to CanalIP-UPMC, for example, the user must validate the identity of the server accepting the certificate appears on the screen in a "popup window". In reality, the user is unable to validate a certificate knowing, because a simple visual check of the license is impossible. Therefore, the certificates of the certification authority (CRU-Cybertrust Educationnal-ca.ca Cybertrust and-global-root-ca.ca) must be installed prior to the browser for the validity of the certificate server can be controlled automatically. Before you connect to the network-UPMC CanalIP you must register in your browser through the certification authority Cybertrust-Educationnal-ca.ca Download the Cybertrust-Educationnal-ca.ca, depending on your browser and select the link below : With Internet Explorer, click on the link following. With Firefox, click on the link following. With Safari, click the link following. If this procedure is not respected, a real risk is incurred by the user: that of being robbed password LDAP directory UPMC. A malicious server may in fact try very easily attack type "man-in-the-middle" by posing as the legitimate server at UPMC. The theft of a password allows the attacker to steal an identity for transactions over the Internet can engage the responsibility of the user trapped ... This is their website : http://www.canalip.upmc.fr/doc/Default.htm (in French, Google-translate it :)) Anyone knows how to install a web certificate on Android?

  • Got black screen when recording screen from xvfb by ffmpeg x11grab device

    - by shawnzhu
    I'm trying to record video from a firefox run by xvfb-run but it always output nothing in the video file except black screen. Here's what I did: start a firefox, open google.com: $ xvfb-run firefox https://google.com Then it will use the default display server number 99. I can see the display information by command xdpyinfo -display :99. A screenshot works very well by command: $ xwd -root -silent -display :99.0 | xwdtopnm |pnmtojpeg > screen.jpg Start using ffmpeg to record a video: $ ffmpeg -f x11grab -i :99.0 out.mpg When I play the video file out.mpg, there's black screen all the time. Is there any parameter I missed? Updates I made progress that the video works instead of black screen only by this command: $ ffmpeg -y -r 30 -g 300 -f x11grab -s 1024x768 -i :99 -vcodec qtrle out.mov Notice it requires the screen resolution matches by specify more options to xvfb-run: $ xvfb-run -s "-screen 0 1224x768x16" -a firefox http://google.com But I still want to get more feedbacks and answers here.
