  • Capture video from WPF app

    - by Julien Couvreur
    I want to write a C# application which can record a video capture of one of its WPF controls. Is there a solution in .Net to record video from a control, or is there some library I could use? My goal is to write a SketchCast application. The use case is the following: launch SketchCast app and press record button, write ink into a WPF ink area, and talk, press stop, recorded voice and ink animation get saved into a video file in some encoding.

  • Android as SIP to GSM gateway

    - by user346034
    Soon I could use a SIP to GSM gateway, because I'll need to make phone calls from Germany to a mobile phone in Czech Republik. Hence, I thought about implementing one. Now, the questions are: Does such a solution already exist (for a reasonable price)? Is it possible to redirect a (voice) stream to a GSM connection with the available Android APIs (SDK or NDK)? Ideas, suggestions, comments are highly welcome.

  • Why JEE is widely used in complicated projects?

    - by cane
    Hi. Yesterday me and my friend we've had nice conversation about IT and he asked me WHY JEE is so widely used when it comes to build complicated IT systems? From my point of view advantages are easily visible, but he is IT manager with a lot of Micro$oft experience (and little Java exp.), so I would like to hear your voice. And I'll give him a link of course. I don't want new .NET - JAVA war - just - why JEE :) Thanks, orsonek

  • Sentence recognition and ability to answer with another sentence

    - by terabytest
    Hi. I'm looking into sentence recognition to make a program that should play voice clips from the game Team Fortress 2. I have .wav files and text files containing the transcription for every sound. What I'd like to make is a system that makes two characters of the game talk to each other (trough playing sound clips), and each one recognises the sense of what the other is saying and tries to answer with another of the available sound clips (trying its best to fit the sense of what it's trying to say) Is that possible in any way?

  • C++ passing arguments to a program already running

    - by wyatt
    I'm reading through a tutorial on using voice commands to control applications and, in an example of controlling rhythmbox, it suggests commands such as the following can be executed: rhythmbox-client --play rhythmbox-client --pause Why does this not simply open a new instance of the program, and how can I emulate the functionality in my own programs? For example, how could I pass a string to a particular instance of a program? Thanks

  • How to assemble a WAV file?

    - by David
    I'm doing an educational project in which 1) I record voice commands on a separate device and after appropriate processing etc... 2) I send 16-bit samples encapsulated in UDP packets over Ethernet to the PC. After receiving the packets and "extracting" data (samples) from them, I need to assemble the samples to a WAV file. Any example code? Any suggestions?

  • What to check to see if server has enough free resources?

    - by kyrisu
    The windows service I am writing will need to run some processor intensive operations once in a while (sound encoding wav - mp3) on a machine that takes part in real time voice communication (so I cannot just run them any-time). What would you check (what counters maybe) before running such operation? Can you point me to any good articles?

    - by Denise McInerney
    Pragmatic Works and the PASS Women in Tech chapter are co-sponsoring a webinar series featuring women speakers. I presented a session on “A Case for Women in Technology” explaining why we are all affected by the lack of women studying and working in tech. The recording is available here. And here are the slides from that presentation: The presentation includes a link to a trailer for an upcoming documentary. This short video makes a good case for why we need more women creating technology. There are many organizations doing good and important work on this issue.

  • Tracking My Internet Provider Speeds

    - by Scott Weinstein
    Of late, our broadband internet has been feeling sluggish. A call to the company took way more hold-time than I wanted to spend, and it only fixed the problem for a short while. Thus a perfect opportunity to play with some new tech to solve a problem, in this case, documenting a systemic issue from a service provider. The goal – a log a internet speeds, taken say every 15 min. Recording ping time, upload speed, download speed, and local LAN usage.   The solution A WCF service to measure speeds Internet speed was measured via speedtest.net LAN usage was measured by querying my router for packets received and sent A SQL express instance to persist the data A PowerShell script to invoke the WCF service – launched by Windows’ Task Scheduler An OData WCF Data Service to allow me to read the data MS PowerPivot to show a nice viz (scratch that, the beta expired) LinqPad to get the data, export it to excel Tableau Public to show the viz     Powered by Tableau

  • Record and Play your WebLogic Console Tasks Like a DVR

    - by james.bayer
    Automation using WebLogic Scripting Tool Today on the Oracle internal mailing list for WebLogic Server questions someone asked how to automate the configuration of the thread model for WebLogic Server and they were having trouble with the jython scripting syntax.  I’ve previously written about this feature called Work Managers and the associated constraints.  However, I did not show how to automate the process of configuring this without the console using WebLogic Scripting Tool – the jython scripting automation environment abbreviated as WLST.  I’ve written some very basic introductions to WLST before and there is also an Oracle By Example on the subject, but this is a bit more advanced.  Fear not because there is a really easy-to-use feature of the WLS console that lets you “Record” user actions just like a DVR.  Using these recordings of the web-based console, you can easily create a script even if you are unfamiliar with the WLST syntax and API.  I’m a big fan of both DVR’s and automation as can be evidenced with this old Halloween picture taken during simpler times.  Obviously the Cast Away and The Big Labowski references show some age.  I was a big Tivo fan-boy back in the day and I still think it’s the best DVR. I strongly believe that WebLogic Scripting Tool (WLST) is an absolutely essential tool for automating administration tasks in anything beyond a development environment.  Even in development environments you can make a case that it makes sense to start the automation for environments downstream.  I promise you that once you start using it for any tasks that you do even semi-regularly, you won’t go back to clicking through the console.  It’s simply so much more efficient and less error-prone to run a script. Let’s say you need to create a Work Manager and MaxThreadsConstraint – the easy way to do it is configure it in the WLS console first while capturing the commands with a recording.  See the images for the simple steps – click to enlarge. Record Console Configurations to a File Review the Recordings and Make Slight Modifications In order to make the recorded .py file directly callable as a stand-alone script I added calls to the connect() and edit() functions at the beginning and calls to disconnect() and exit() at the end – otherwise the main section of the script was provided by the console recording.  Below is the resulting file I saved as d:/temp/wm.py connect('weblogic','welcome1', 't3://localhost:7001') edit() startEdit()   cd('/SelfTuning/wl_server') cmo.createMaxThreadsConstraint('MaxThreadsConstraint-0')   cd('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName)) cmo.setCount(5) cmo.unSet('ConnectionPoolName')   cd('/SelfTuning/wl_server') cmo.createWorkManager('WorkManager-0') cd('/SelfTuning/wl_server/WorkManagers/WorkManager-0') set('Targets',jarray.array([ObjectName('com.bea:Name=examplesServer,Type=Server')], ObjectName))   cmo.setMaxThreadsConstraint(getMBean('/SelfTuning/wl_server/MaxThreadsConstraints/MaxThreadsConstraint-0')) cmo.setIgnoreStuckThreads(false)   activate() disconnect() exit() Run the Script If you want to test it be sure to delete the Work Manager and MaxThreadConstraint that you had previously created in the console.  Do something like the following - set up the environment and tell WLST to execute the script which happens in the first 2 lines, the rest doesn’t require any user input: D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server\bin>setDomainEnv.cmd D:\Oracle\wls11g\wlserver_10.3\samples\domains\wl_server>java weblogic.WLST d:\temp\wm.py   Initializing WebLogic Scripting Tool (WLST) ...   Welcome to WebLogic Server Administration Scripting Shell   Type help() for help on available commands   Connecting to t3://localhost:7001 with userid weblogic ... Successfully connected to Admin Server 'examplesServer' that belongs to domain 'wl_server'.   Warning: An insecure protocol was used to connect to the server. To ensure on-the-wire security, the SSL port or Admin port should be used instead.   Location changed to edit tree. This is a writable tree with DomainMBean as the root. To make changes you will need to start an edit session via startEdit().   For more help, use help(edit)   Starting an edit session ... Started edit session, please be sure to save and activate your changes once you are done. Activating all your changes, this may take a while ... The edit lock associated with this edit session is released once the activation is completed. Activation completed Disconnected from weblogic server: examplesServer     Exiting WebLogic Scripting Tool.   Now if you go back and look in the console the changes have been made and we now have a compete script.  Of course there is a full MBean reference and you can learn the nuances of jython and WLST, but why not the WLS console do most of the work for you!  Happy scripting.

  • Data Warehouse Best Practices

    - by jean-pierre.dijcks
    In our quest to share our endless wisdom (ahem…) one of the things we figured might be handy is recording some of the best practices for data warehousing. And so we did. And, we did some more… We now have recreated our websites on Oracle Technology Network and have a separate page for best practices, parallelism and other cool topics related to data warehousing. But the main topic of this post is the set of recorded best practices. Here is what is available (and it is a series that ties together but can be read independently), applicable for almost any database version: Partitioning 3NF schema design for a data warehouse Star schema design Data Loading Parallel Execution Optimizer and Stats management The best practices page has a lot of other useful information so have a look here.

  • Annoying security "feature" in Windows 2008 R2 burns me, but not DVD's

    - by Stan Spotts
    This stuff drives me nuts. I'm all for hardening servers, and reducing security footprints, but I always want the option to allow me to get work done versus securing my system. I use Windows Server 2008 R2 as my laptop OS for a number of reasons I don't need to review here. It's pimped out to work like Windows 7 for most things. But my DVD writer is crippled, and evidently it's on purpose: http://blogs.technet.com/askcore/archive/2010/02/19/windows-server-2008-r2-no-recording-tab-for-cd-dvd-burner.aspx I don't WANT to log in as the local administrator to burn a damned DVD.  WTF isn't this configurable through the registry, or better yet, group policy? There are no security settings that I should not have the option to enable or disable.

  • AJI Report with Nat Ryan&ndash;Discussion about Game Development with Corona Labs SDK

    - by Jeff Julian
    We sat down with Nat Ryan of Fully Croisened to talk about Game Development and the Corona Labs framework. The Corona SDK is a platform that allows you to write mobile games or applications using the Lua language and deploy to the iOS and Android platforms. One of the great features of Corona is the compilation output is a native application and not a hybrid application. Corona is very centered around their developer community and there are quite a few local meetups focused on the helping other developers use the platform. The community and Corona site offers a great number of resources and samples that will help you get started in a matter of a few days. If you are into Game Development and want to move towards mobile, or a business developer looking to turn your craft back into a hobby, check out this recording and Corona Labs to get started.   Download the Podcast   Site: AJI Report – @AJISoftware Site: Fully Croisened Twitter: @FullyCroisened Site: Corona Labs

  • Fusion HCM SaaS – Integration

    - by Kiran Mundy
    v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Fusion HCM SaaS – Integration A typical implementation pattern we’re seeing with Fusion Apps early adopters is implementing a few Fusion HCM applications that bring the most benefit to their company with the least disruption to existing programs and interfaces. Very often this ends up being Fusion Goals & Performance, Talent, Compensation or Benefits, often with Taleo for recruiting. The implementation picture looks like what you see below: Here, you can see that all the “downstream integrations” from the On-Premise Core HR, are unaffected because the master for employee data is still your On-Premise Core HR system – all updates and new hires are made here (although they may be fed in from Taleo to start with). As a second phase when customers migrate Core HR to Fusion HCM, they have to come up with a strategy to manage integrations to all their downstream applications that require employee details. For customers coming from EBS HR, a short term strategy that allows for minimal impact, is to extract employee data from Fusion (Via HCM Extract), and load the shared EBS HR tables (which are part of an EBS Financials install anyways), and let your downstream integrations continue to function based on this data as shown below. If you are not coming from EBS HR and there are license implications, you may want to consider: Creating an On-Premise warehouse for extracting data from Fusion Apps. Leveraging Fusion Apps Web Services (available to SaaS customers starting R7) to directly retrieve/write data to Fusion Apps. Integration Tools File Based Loader This is the primary mechanism for loading HCM data (both initial load and incremental updates) into Fusion HCM. Employee & related data can be uploaded into Fusion HCM using File Based Loader. Note that ability to schedule File Based Loader to run on a pre-defined schedule will be available as a patch on top of Rel 5. Hr2Hr has been deprecated in favor of File Based Loader, but for existing customers using Hr2Hr, here are some sample scripts that show how to get more informative error messages. They can be run by creating data model sql queries in BI Publisher. The scripts currently have hard coded values for request id and loader batch id, which your developer will need to update to the correct values for you. The BI Publisher Training Session recorded on Apr 18th is available here (under "Recordings"). This will enable a somewhat technical resource to create a data model sql query. Links to Documentation & Traning Reference documentation for File Based Loader on docs.oracle.com FBL 1.1 MOS Doc Id 1533860.1 Sample demo data files for File Based Loader HCM SaaS Integrations ppt and recording. EBS api's Loading Information into EBS Full or Shared HCM This could be candidate information being loaded from Taleo into EBS or  Employee information being loaded from Fusion HCM into an EBS shared HR install (for downstream applications & EBS Financials).

Page 2-15 of the User Documentation describes how to use the benefits extract. Benefit enrollments can also be uploaded into Fusion Benefits. Instructions are here along with a sample upload file. However, if the defined benefits extract does not meet your requirements, you can use BI Publisher (Link to BI Publisher presentation recording from Apr 18th) to create your own version of Benefits extract. You can start with the data model query underlying the benefits extract.

  • Comparing a saved movement with other movement with Kinect

    - by Ewerton
    I need to develop an application where a user (physiotherapist) will perform a movement in front of the Kinect, I'll write the data movement in the database and then the patient will try to imitate this motion. The system will calculate the similarity between the movement recorded and executed. My first idea is, during recording (each 5 second, by example), to store the position (x, y, z) of the points and then compare them in the execution time(by patient). I know that this approach is too simple, because I imagine that in people of different sizes the skeleton is recognized differently, so the comparison is not reliable. My question is about the best way to compare a saved motion with a movement executed (on the fly). PS: Sorry by my English.

  • Ubuntu 12.10 Skype cannot use Web Cam Microphone

    - by f.cipriani
    This is making me crazy. After upgrading to Ubuntu 12.10, Skype 4.1.0.20 cannot use my Logitech Web Cam microphone anymore, it keeps using the front panel microphone. I can record correctly from the web cam microphone using the sound recorder the web cam microphone is selected in the sound settings I have tried using pavucontrol I have even shut down pulseaudio and set the web cam microphone device in the skype options manually No matter what, Skype will keep recording using the front panel microphone. Everything was working fine with Ubuntu 12.04 before I upgraded to 12.10. Update: the webcam icon is grayed during calls, even tough everything looks ok in the video options . This makes me think skype has some problems in fully recognizing my web cam.
