  • USB Audio Device Loopback Through Speakers

    - by matto1990
    I have a USB turntable which when plugged in to my ubuntu 10.10 machine appears in the audio settings as an input device (USB PnP Audio Device Analog Stereo) like a microphone. What I'd like to be able to do it to have the sound for that audio device played back through the audio output (speaker or whatever). I'm not too worried if there's a slight delay between the audio coming in and it being played out through the speakers. As far as I'm aware this is refereed to as software loopback. I can achieve exactly what I want if I open Audacity, enable software loopback and press record. Obvious this isn't ideal as I don't really want it recording what I'm playing all the time. I know this is possible because of the Audacity example however I'd like to know if there's a way to do it without it recording. I've search around for a while for a piece of software that does this, however I couldn't get anything even close. Any help would be greatly appreciated.

  • JavaOne 2012 LAD Session: The Future of JVM Performance Tuning

    - by Ricardo Ferreira
    Hi folks. This year, together with the Oracle Open World Latin America, happened another edition of the JavaOne Latin America, the more important event of Java for the developers community. I would like to share with you the slides that I've used in my session. The session was "The Future of JVM Performance Tuning" and the idea was to share some knowledge about JVM enhancements that Oracle implemented in Hotspot about performance, specially those ones related with GC ("Garbage Collection") and SDP ("Sockets Direct Protocol"). I hope you enjoy the content :)

  • Where can I find accessible bug/issue databases with complete revision history

    - by namenlos
    I'm performing some research and analysis on bug/issue tracking databases and more specifically on how programmers and teams of programmers actually interact with them. What I'm looking for involves understanding how those databases change over time. So what I don't need for example: is a database of all the bugs of some open source project as the bugs exist today. What I do need is a complete set of revision history for every issue/bug in the database. This would enable me to pick a specific datetime and say here were the list of all the issues/bugs that existed at that moment in time. Anyway know of some publicly accessible issue/bug databases that expose this revision data? Ideally, the revision would look something like this (shown for a single bug, with two revisions) ISSUEID PRI SEV ASSIGNEDTO MODIFIEDON VALIDUNTIL 1 2 2 mel apr-1-2010:5pm apr-1-2010:6pm 1 2 3 steve apr-1-2010:6pm NULL

  • My computer will no longer suspend or shut off when I close the lid

    - by dave
    This is somewhat annoying. I have an old laptop and the screen on it is shot, so now I have an old monitor hooked up and it works fine. Before the upgrade I had it set so that when i closed the lid on the laptop everything would shutdown or suspend, when I lift the lid, everything would come back. Now, however, when i close the lid nothing happens, when i open the lid the screen flashes black and comes back. I have it set so that it should suspend when i close the lid. It's confusing...

  • How can I map the docky anchor button so that it will launch the unity dash?

    - by user76179
    Example of a Docky Dock I have the Docky dock on my desktop. It has an anchor logo button (as seen on the left side image of the link above) that brings up the Docky settings. I want to map it so that it opens my dash instead. I believe I can do this through gconf and by setting the docky button to either my super key or the necessary path required to open the dash function (but I do not know this path or how to code a button to a keyboard key). How can I map the docky anchor button so that it will launch the unity dash (as similar to when you simply tap the super key)?

  • Chicago Architects Group &ndash; Document Generation Architectures

    - by Tim Murphy
    Thank you to everyone who came out to the Chicago Architects Group presentation last night.  It seemed like the weather has a way of keeping a large portion of the people who registered from making the meeting.  There was some lively networking going on before and after the meeting.  I enjoyed the questions that people had during the presentation.  It helped to bring out some of the challenges with dealing with the OOXML and ODF standards from an architecture perspective. I have posted the Slides and Code.  Feel free to contact me with any questions. For those of you who missed the presentation I will be giving a similar one at the Lake County .NET Users Group on June 24th. The next CAG presentation will be July 20th.  The presentation will be Architecting A BI Installation by David Leininger.  Look for the registration to open in the next day or so. del.icio.us Tags: Chicago architects Group,OOXML,ODF,BI,LCNUG,slides,code

  • Microsoft BUILD 2013 Day 1&ndash;Keynote

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/microsoft-build-2013-day-1ndashkeynote.aspx This one is going to be a little long because the keynote was jam-packed so bare with me. The keynote for the first day of BUILD 2013 was kicked off by Steve Balmer.  He made it very clear that Microsoft’s focus is on accelerating its time to market with products and product updates.  His quote was that “Rapid release” is the new norm.  He continued by showing off several new Lumias that have been buzzing around the internet for a while and announce that Sprint will now be carrying the HTC 8XT and Samsung ATIV. Balmer is known for repeating words or phrase for affect.  This time it was “Rapid release, rapid release” and “Touch, touch, touch, touch, touch, …”.  This was fun, but even more fun was when he announce that all attendees would receive an Acer Iconia 8” tablet. SCORE! The next subject Balmer focused on is new apps.  The three new ones were Flipboard, Facebook and NFL Fantasy Football.  I liked the first two because these are ones that people coming from other platforms are missing.  The NFL app is great just because it targets a demographic that can be fanatical.  If these types of apps keep coming than the missing app argument goes away. While many Negative Nancy’s are describing Windows 8.1 as Windows 180 Steve Balmer chose to call it a “refined blend” as in a coffee that has been improved with a new mix.  This includes more multi-tasking options and leveraging Bing straight throughout the entire ecosystem. He ended this first section by explaining that this will also bring more Bing development opportunities to the community. Steve Balmer was followed by Julie Larson-Green who spent her time on stage selling us on Windows 8 all over again from my point of view.  Something that I would not have thought was needed until I had listened to some other attendees who had a number of concerns and complaints.  She showed a number of new gestures that will come with Windows 8.1, and while they were cool I was left wondering if they really improved the experience.  I guess only time will tell. I did like the fact that it the UI implementation to bring up “All Apps” now mirrors that of Windows Phone.  The consistency is a big step forward that I hope to see continue.  The cool factor went up from there as she swiped content from a desktop (mega-tablet) to the XBox One.  This seamless experience I believe is what is really needed for any future platform to be relevant. I was much more enthused by the presentation of Antoine Leblond who humbled us by letting us know that there are 5k new API.  How that can be or how anyone would ever use all of them is another question.  His announcement was that the Visual Studio 2013 preview would be available today along with the Windows 8.1 bits.  One of the features of VS2013 that he demonstrated is the power consumption profiler.  With battery life being a key factor with consumer consumption devices this is a welcome addition. He didn’t limit his presentation to VS2013 features though.  He showed how the Store has been redesigned to enable better search and discoverability of apps and how Win 8.1 can perform multiple screen scales depending on the resolution of the device automatically.  The last feature he demoed was the real time video streaming API which he made sure we understood by attaching a Surface to a little robot.  Oh, but there was one more thing.  Antoine and Julie announce that all attendees would also be getting Surface Pros.  BONUS! How much more could there be?  Gurdeep Singh Pall was about to pile on.  He introduced us to Bing as a platform (BaaP?).  He said if they (Microsoft) could do something with and API that is good 3rd party developers can do something that is dynamite and showed us some of the tools they had produced.  These included natural user interface improvements such as voice commands that looked to put Siri to shame.  Add to that 3D, OCR and translation capabilities and the future looks to be full of opportunities. Balmer then came out to show us one last thing.  Project Spark is a game design environment that will be available for Windows 8.1, XBox 360 and XBox One.  All I can say is that if my kids get their hands on this they are going to be able to learn some of what dad does in a much more enjoyable way. At the end of it all I was both exhausted and energized by what I saw.  What could they have possibly left for the day 2 keynote?  I hear it will feature Scott Hanselman.  If that is right we are in for a treat.  See you there. del.icio.us Tags: BUILD 2013,Windows 8.1,Winodws Phone,XAML,Keynote,Bing,Visual Studio 2013,Project Spark

  • How to remove tearing in videos with Nvidia driver?

    - by Daimon
    I'm using ubuntu 11.10 as my HTPC OS on ION board. Tearing was always a big problem but this guide (http://www.omgubuntu.co.uk/2010/01/how-to-fix-video-tearing-in-videos-nvidia-ubuntu/) used to solve it in previous versions. I mean it used to because it doesn't solve it anymore. I tried making same changes (although compiz config is little different and same options are in different panels) but with no success. I also tried to manually set resolution and refresh rate of HDTV in nvidia settings - no changes at all. I know that open source drivers would solve a problem but it's not an option because I need VDPAU acceleration. I've also read that completely disabling of Composite solves the problem - can't do that because compizconfig-settings-manager crashes on attempt.

  • Standard -server to server- and -browser to server- authentication method

    - by jeruki
    I have server with some resources; until now all these resources were requested through a browser by a human user, and the authentication was made with an username/password method, that generates a cookie with a token (to have the session open for some time). Right now the system requires that other servers make GET requests to this resource server but they have to authenticate to get them. We have been using a list of authorized IPs but having two authentication methods makes the code more complex. My questions are: Is there any standard method or pattern to authenticate human users and servers using the same code? If there is not, are the methods I'm using now the right ones or is there a better / more standard way to accomplish what I need? Thanks in advance for any suggestion.

  • apt-get install does not work. Gives the same error every time E: Unable to locate package

    - by SAMEER
    There is an issue, for every package that I try to install. I am using VMWare Player 3.16 & I have installed Ubuntu 12.04. The error is: E:Unable to locate package (PACKAGE NAME) Also, another problem is that there are some configuration errors. So I have to use the CLI rather than the GUI. Now if this is a network error, I'm not sure as to how to open the setting from the command prompt. Even if I get to the GUI, it might not work, as the shortcuts are not available.

  • Ubuntu 12.10 automatic logout

    - by anthony
    I just had a new desktop constructed and installed ubuntu 12.10 which was successful for the most part but every time I open up some applications like thunderbird I get automatically logged out and all my windows are closed. System error messages also come up from time to time. Also I'm not sure if this helps but if I select the "Use system title bar and borders" in chromium I will also get logged out and from that point won't be able to use it without getting logged out in the future. If I click on particular links as well. If anyone has any tips on how I can isolate and fix the problem I would greatly appreciate it.

  • Is there a preferred way to set up a virtual Ubuntu server on a desktop?

    - by Keith Groben
    I love Ubuntu, and as I am searching the internet, I am finding that some questions I have have not been answered yet. One of them is if there is a preferred way to set up a virtual server. I look through the Ubuntu Software Center, but found nothing from the search "Virtual Server" I then searched the internet and found lots of posts to trouble-shoot VMWare virtual servers. So, like a good researcher I looked in the Software center for VMWare. Sure enough I found "user agent" and "view open client". I didn't get sufficient info from the software center. And searching the website only left me scratching my head. I want to install Ubuntu Server Edition. I already have a server, but am cautious "trying out" things on it. So a virtual server sounds like what I need.

  • Forcing Nautilus to use Kerberos (Active Directory) authentication

    - by user14146
    Is there a way to get Nautilus or any other file manager that runs on Ubuntu 11.04 to use Kerberos for authentication? I'm using Likewise Open to join machines to the domain, and I can't type in passwords for every user on every computer that needs to mount a network share. I've been able to get Kerberos working with the command line smbclient, but oddly Kerberos does not seem to be Nautilus-integrated. I also checked the SSH config file, and it looks like you can enable GSSAPIAuthentication, but it only works for Kerberos v2, not the current version, which I think is v5.

The system has kernel support for UDF installed, I can mount above ISO (mount -o loop) and see its content read only. Any idea how to fix it? Using other than isomaster tool is also an option.
