  • Stream audio to mobile device

    - by blackn1ght
    I'd like to stream the audio from Ubuntu 10.10 to my HTC Desire HD (Android 2.2). I've seen solutions so far for streaming from audio players, but I'd like to stream any audio output from the PC to my phone. My use case is for watching TV/Films in VLC or online (BBC iPlayer) in bed, without having to use my surround sound system which is likely to wake up my house mates. I'm not just talking about music from Banshee, but any audio that the system makes. I was thinking that PulseAudio is pretty powerful, is it possible to route audio through that to a mobile device? Can it be done through bluetooth? Cheers in advance!

  • What can a Service do on Windows?

    - by Akemi Iwaya
    If you open up Task Manager or Process Explorer on your system, you will see many services running. But how much of an impact can a service have on your system, especially if it is ‘corrupted’ by malware? Today’s SuperUser Q&A post has the answers to a curious reader’s questions. Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Forivin wants to know how much impact a service can have on a Windows system, especially if it is ‘corrupted’ by malware: What kind malware/spyware could someone put into a service that does not have its own process on Windows? I mean services that use svchost.exe for example, like this: Could a service spy on my keyboard input? Take screenshots? Send and/or receive data over the internet? Infect other processes or files? Delete files? Kill processes? How much impact could a service have on a Windows installation? Are there any limits to what a malware ‘corrupted’ service could do? The Answer SuperUser contributor Keltari has the answer for us: What is a service? A service is an application, no more, no less. The advantage is that a service can run without a user session. This allows things like databases, backups, the ability to login, etc. to run when needed and without a user logged in. What is svchost? According to Microsoft: “svchost.exe is a generic host process name for services that run from dynamic-link libraries”. Could we have that in English please? Some time ago, Microsoft started moving all of the functionality from internal Windows services into .dll files instead of .exe files. From a programming perspective, this makes more sense for reusability…but the problem is that you can not launch a .dll file directly from Windows, it has to be loaded up from a running executable (exe). Thus the svchost.exe process was born. So, essentially a service which uses svchost is just calling a .dll and can do pretty much anything with the right credentials and/or permissions. If I remember correctly, there are viruses and other malware that do hide behind the svchost process, or name the executable svchost.exe to avoid detection. Have something to add to the explanation? Sound off in the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.

  • Rebooting problem

    - by Vinoth
    After restarting my ubuntu PC, I am getting a dialog window showing "Your system is running in low graphics mode" and after clicking on 'OK', I was prompted with three options 1. Run in low graphics mode for just one session 2. Reconfigure graphics 3. Troubleshoot the error 4. Exit to console login When I troubleshoot the error, its showing the black screen with following lines which I remember: we do not own /var/log/pm-powersave.log ....................................... couldn't write bytes: Broken pipe ....................................... ....................................... Starting System V runlevel compatibility got strucked at this point. Actually before restarting, I have changed the owner for all the files under the directory "/var/log" and "/var/lib". Is there any relation with the above issue. Please help me out to resolve the issue. Its urgent.

  • How to fix 'grub error file not found' when installing 12.04?

    - by Tomasz Grabowski
    i'm trying to install Ubuntu. I don't know if it is important, but i'm trying to install it on external HDD. In the end i have external bootable HDD which only displays: error: file not found grub recovery> From the beginning: I've downloaded ubuntu-12.04-desktop-i386.iso I've used LiLi USB Creator (LinuxLive) to create bootable pendrive from that image I've bootet from it, it works I've clicked "Try ubuntu", it works too. I've used GParted to look over drivers (disks) My primary embedded disk is seen as /dev/sda My attached external disk as /dev/sdb My PenDrive as /dev/sdc I've created partitions on /dev/sdb Fist partition for system (over 200GiB) Second was there already (it's xsf, and i don't want to touch it :P) Third is extended partition, with 1 locital partiton (10GiB) for swap I've started installation i've choose "somethin else" in ... i belive secound screeb then is selected /dev/sdb as boot disk for first partiton of /dev/sdb i set i want ext3 file system, i've check "formattin" checkbox, and mount path set to "/" firs logical partiton set as swap partition After installation finished, i restarted my computer. When i boot from my primary disc it's work ok, my previous operating system - vista - works ok. When i set my BIOS to boot from my external disc, i only get that message: error: file not found grub recovery> I've try to reinstall it, but didn't help... In desperation, i've try to read a bit about that "grub recovery" command-line and experiment a bit... I'm not sure if this has had any point, or if it give you some information (notice, that i don't know what i'm doing :P ) when i've type command: insmod (hd1,1)/boot/grub/linux.mod i've get message: unknown filesystem the same with: insmod (hd1,msdos1)/boot/grub/linux.mod the same with: insmod ext3 but i get no message after command: insmod ext2 ... notice that i really don't know what this command exactly do, but than i thought that maybe if i reinstall ubuntu with ext2 filesystem, it will work. I've done that, but symptoms are the same. I've go back to that Live version of ubuntu, filesystem and basics directories seems to be present on /dev/sdb1 ... i'm completely unfamiliar with GRUB. I'm also don't know which wersion of GRUB it is, i hope there is only one version on ubuntu-12.04-desktop-i386.iso Any help? Thax

  • Interviewing someone for general unix skills

    - by Christophe Vanfleteren
    How would you test a developer that claims to have *nix shell experience (just to be clear, we don't want to test if someone can develop on *nix, only that they know their way around the command line). I was thinking about making them solve a problem of getting information out of log files, which would involve some basics like cat, grep, cut, ... combined with piping. What other basic knowledge would you ask for? Once again, this isn't for interviewing someone who will develop for *nix systems, and also not for *nix system admins, but just for regular developers that sometimes need to do some work on a *nix system.

  • SQLAuthority News – Download Whitepaper – SQL Server Analysis Services to Hive

    - by pinaldave
    The SQL Server Analysis Service is a very interesting subject and I always have enjoyed learning about it. You can read my earlier article over here. Big Data is my new interest and I have been exploring it recently. During this weekend this blog post caught my attention and I enjoyed reading it. Big Data is the next big thing. The growth is predicted to be 60% per year till 2016. There is no single solution to the growing need of the big data available in the market right now as well there is no one solution in the business intelligence eco-system available as well. However, the need of the solution is ever increasing. I am personally Klout user. You can see my Klout profile over. I do understand what Klout is trying to achieve – a single place to measure the influence of the person. However, it works a bit mysteriously. There are plenty of social media available currently in the internet world. The biggest problem all the social media faces is that everybody opens an account but hardly people logs back in. To overcome this issue and have returned visitors Klout has come up with the system where visitors can give 5/10 K+ to other users in a particular area. Looking at all the activities Klout is doing it is indeed big consumer of the Big Data as well it is early adopter of the big data and Hadoop based system.  Klout has to 1 trillion rows of data to be analyzed as well have nearly thousand terabyte warehouse. Hive the language used for Big Data supports Ad-Hoc Queries using HiveQL there are always better solutions. The alternate solution would be using SQL Server Analysis Services (SSAS) along with HiveQL. As there is no direct method to achieve there are few common workarounds already in place. A new ODBC driver from Klout has broken through the limitation and SQL Server Relation Engine can be used as an intermediate stage before SSAS. In this white paper the same solutions have been discussed in the depth. The white paper discusses following important concepts. The Klout Big Data solution Big Data Analytics based on Analysis Services Hadoop/Hive and Analysis Services integration Limitations of direct connectivity Pass-through queries to linked servers Best practices and lessons learned This white paper discussed all the important concepts which have enabled Klout to go go to the next level with all the offerings as well helped efficiency by offering a few out of the box solutions. I personally enjoy reading this white paper and I encourage all of you to do so.

  • Would you use UML if it kept stakeholders from requesting changes frequently?

    - by Huperniketes
    As much as programmers hate to document their code/system and draw UML (especially, Sequencing, Activity and State machine diagrams) or other diagramming notation, would you agree to do it if it kept managers from requesting a "minor change" every couple of weeks? IOW, would you put together visual models to document the system if it helped you demonstrate to managers what the effect of changes are and why it takes so long to implement them? (Edited to help programmers understand what type of answer I'm looking for.) 2nd edit: Restating my question again, "Would you be willing to use some diagramming notation, against your better nature as a programmer, if it helped you manage change requests?" This question isn't asking if there might be something wrong with the process. It's a given that there's something wrong with the process. Would you be willing to do more work to improve it?

  • How can I refactor client side functionality to create a product line-like generic design?

    - by Nupul
    Assume the following situation similar to that of Stack Overflow: I have a system with a front-end that can perform various manipulations on the data (by sending messages to REST back-end): Posting Editing and deleting Adding labels and tags Now in the first version we created it well modularized but the need as of now for 'evolving' the system similar to Stack Overflow. My question is how best to separate the commonality and how to incorporate the variability with respect to the following: Commonality: The above 'functionalities' and sending/receiving the data from the server Look and feel (also a variability as explained below) HTTP verbs associated with the above actions Variability: The RESTful URLs where the requests are sent The text/style of the UI (the commonality is analogous to Stack Overflow - the functionality of upvotes, posting a question remains the same, but the words, the icons, the look and feel is still different across sites) I think this is entirely a client-side code organization/refactoring issue. I'm heavily using jQuery, javascript and backbone for front-end development. My question is how best should I isolate the same to be able to create multiple such aspects to the tool we are currently working on?

  • EPM Architecture: Foundation

    - by Marc Schumacher
    This post is the first of a series that is going to describe the EPM System architecture per component. During the following weeks a couple of follow up posts will describe each component. If applicable, the component will have its standard port next to its name in brackets. EPM Foundation is Java based and consists of two web applications, Shared Services and Workspace. Both applications are accessed by browser through Oracle HTTP Server (OHS) or Internet Information Services (IIS). Communication to the backend database is done by JDBC. The file system to store Lifecycle Management (LCM) artifacts can be either local or remote (e.g. NFS, network share). For authentication purposes, the EPM Product Suite can connect to external directories or databases. Interaction with other EPM Suite components like product specific Lifecycle Management connectors or Reporting and Analysis Web happens through HTTP protocol. The next post will cover Reporting and Analysis.

  • New channels for Exadata 11.2.3.1.1

    - by Rene Kundersma
    With the release of Exadata 11.2.3.1.0 back in April 2012 Oracle has deprecated the minimal pack for the Exadata Database Servers (compute nodes). From that release the Linux Database Server updates will be done using ULN and YUM. For the 11.2.3.1.0 release the ULN exadata_dbserver_11.2.3.1.0_x86_64_base channel was made available and Exadata operators could subscribe their system to it via linux.oracle.com. With the new 11.2.3.1.1 release two additional channels are added: a 'latest' channel (exadata_dbserver_11.2_x86_64_latest) a 'patch' channel (exadata_dbserver_11.2_x86_64_patch) The patch channel has the new or updated packages updated in 11.2.3.1.1 from the base channel. The latest channel has all the packages from 11.2.3.1.0 base and patch channels combined.  From here there are three possible situations a Database Server can be in before it can be updated to 11.2.3.1.1: Database Server is on Exadata release < 11.2.3.1.0 Database Server is patched to 11.2.3.1.0 Database Server is freshly imaged to 11.2.3.1.0 In order to bring a Database Server to 11.2.3.1.1 for all three cases the same approach for updating can be used (using YUM), but there are some minor differences: For Database Servers on a release < 11.2.3.1.0 the following high-level steps need to be performed: Subscribe to el5_x86_64_addons, ol5_x86_64_latest and  exadata_dbserver_11.2_x86_64_latest Create local repository Point Database Server to the local repository* install the update * during this process a one-time action needs to be done (details in the README) For Database Servers patched to 11.2.3.1.0: Subscribe to patch channel  exadata_dbserver_11.2_x86_64_patch Create local repository Point Database Server to the local repository Update the system For Database Servers freshly imaged to 11.2.3.1.0: Subscribe to patch channel  exadata_dbserver_11.2_x86_64_patch Create local  repository Point Database Server to the local repository Update the system The difference between 'situation 2' (Database Server is patched to 11.2.3.1.0) and 'situation 3' (Database Server is freshly imaged to 11.2.3.1.0) is that in situation 2 the existing Exadata-computenode.repo file needs to be edited while in situation 3 this file is not existing  and needs to be created or copied. Another difference is that you will end up with more OFA packages installed in situation 2. This is because none are removed during the updating process.  The YUM update functionality with the new channels is a great enhancements to the Database Server update procedure. As usual, the updates can be done in a rolling fashion so no database service downtime is required.  For detailed and up-to-date instructions always see the patch README's 1466459.1 patch 13998727 888828.1 Rene Kundersma

  • No sound from internal speaker but headphones OK

    The problem: The system won't play sound on the internal speaker of the laptop, but only on the headphone.

  • Is Java's ElementCollection Considered a Bad Practice?

    - by SoulBeaver
    From my understanding, an ElementCollection has no primary key, is embedded with the class, and cannot be queried. This sounds pretty hefty, but it allows me the comfort of writing an enum class which also helps with internationalization (using the enum key for lookup in my ResourceBundle). Example: We have a user on a media site and he can choose in which format he downloads the files @Entity @Table(name = "user") public class User { /* snip other fields */ @Enumerated @ElementCollection( targetClass = DownloadFilePreference.class, fetch = FetchType.EAGER ) @CollectionTable(name = "download_file_preference", joinColumns = @JoinColumn(name = "user_id") ) @Column(name = "name") private Set<DownloadFilePreference> downloadFilePreferences = new HashSet<>(); } public enum DownloadFilePreference { MP3, WAV, AIF, OGG; } This seems pretty great to me, and I suppose it comes down to "it depends on your use case", but I also know that I'm quite frankly only an initiate when it comes to Database design. Some best practices suggest to never have a class without a primary key- even in this case? It also doesn't seem very extensible- should I use this and gamble on the chance I will never need to query on the FilePreferences?

  • LDoms and Maintenance Mode

    - by Owen Allen
     I got a few questions about how maintenance mode works with LDoms. "I have a Control Domain that I need to do maintenance on. What does being put in maintenance mode actually do for a Control Domain?" Maintenance mode is what you use when you're going to be shutting a system down, or otherwise tinkering with it, and you don't want Ops Center to generate incidents and notification of incidents. Maintenance mode stops new incidents from being generated, but it doesn't stop polling, or monitoring, the system and it doesn't prevent alerts. "What does maintenance mode do with the guests on a Control Domain?" If you have auto recovery set and the Control Domain is a member of a server pool of eligible systems, putting the Control Domain in maintenance mode automatically migrates guests to an available Control Domain.  When a Control Domain is in maintenance mode, it is not eligible to receive guests and the placement policies for guest creation and for automatic recovery won't select this server as a possible destination. If there isn't a server pool or there aren't any eligible systems in the pool, the guests are shut down. You can select a logical domain from the Assets section to view the Dashboard for the virtual machine and the Automatic Recovery status, either Enabled or Disabled. To change the status, click the action in the Actions pane. "If I have to do maintenance on a system and I do not want to initiate auto-recovery, what do I have to do so that I can manually bring down the Control Domain (and all its Guest domains)?" Use the Disable Automatic Recovery action. "If I put a Control Domain into maintenance mode, does that also put the OS into maintenance mode?" No, just the Control Domain server. You have to put the OS into maintenance mode separately. "Also, is there an easy way to see what assets are in maintenance mode? Can we put assets into, or take them out of, maintenance mode on some sort of group level?" You can create a user-defined group that will automatically include assets in maintenance mode. The docs here explain how to set up these groups. You'll use a group rule that looks like this:

    Upgraded to 11.04, from 10.10 system would only come up in terminal mode, but it told me that an additional upgrade was available and did I want to do that. Foolishly thinking that might fix the problem, I said yes. This time it did not make it all the way through the upgrade, when I came back to the computer over an hour later, the screen was filled with an error message "could not open display", had to reboot. Went to recovery mode on reboot to install nvidia module, when I rebooted system came up fine, but without carrying over my personal folders, I have the home folder, but no personal named folder in it. Came to Ubuntu One, but gives error message; File Sync error. (org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked Is the a way around this in order to restore my files? I know my files existed on Ubuntu one as of a few months ago.

  • How do you put a database online?

    - by Dezrik
    I have a very beginner question regarding web development. I've had some experience with JSP, Hibernate, and MAMP to create a simple system for tracking inventory and sales. But this was all done locally on one computer. This time, I want to create a system that could be accessible online. It's to help my mother track her business wherever she goes. So there would be similar aspects like tracking inventory and sales. I understand that you have to have a server in which to host all the files in. But I don't understand how you can access your database online. Or what sorts of applications or products should be used. Currently the host of my database is localhost. How do put it online such that you can still do CRUD operations? Are there any guides to do this?
