• Partner case - ISE (Germany) - IDS brings light into Investment Controlling with Exadata

  - by Javier Puerta

  (Original post in German: IDS bringt mit Exadata Licht ins Investmentcontrolling) "The amount of data that IDS GmbH (Analysis and Reporting Services) has to cope with daily, is enormous: at the subsidiary of Allianz SE all the services are around Investment Controlling.The company needed an extensible data warehouse solution in which all the data could be merged together, harmonized and enriched. Finally IDS decided for Exadata to be as optimal solution, specifically the Oracle Exadata Database Machine. The implementation was carried out jointly with the Oracle Platinum Partner ISE, who took over the technical and advisory support part and will be IDS´ preffered consultant in any further Exadata development. See how Exadata is used and why this investment has paid off for IDS, by watching watching the following video (in German)"

• transfer Thunderbird (17) Profile on Win7 to Ubuntu 12.04

  - by William Curran

  I want to transfer Thunderbird Profile on Win7 to thunderbird (17) Ubuntu 12.04. I already copied the profile folder from Windows to Ubuntu and modified progile.ini on the ubuntu machine to include [Profile] Name=Bill IsRelative=1 Path=(the name of the transfered profile folder) I think the problem is that the Win. TB profile content (files and folder structure) look VERY different that the that of the unbuntu TB profile's that was created on installation. The Ubuntu install is new where as the Win TB has undergone many updates. Seems the system for profile storage has changed drastically. I tried to start TB in safe mode but could't get the path correct to start TB in the terminal with the -safe-mode switch. What can I do? Bill

• Ubuntu 12.04 intermittently fails to wake up from sleep

  - by stacksia

  When I put my Ubuntu 12.04 machine into sleep, sometimes on waking up, it fails, logs me out, and takes me back to login screen. When I log back in, it tells me some unexpected error happened, but it fails to let me report the bug. This has started to happen recently, but I don't know what triggered it. uname -a Linux [name] 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The issue seems similar to Xorg intermittently restarts after suspend. But in my case I am not sure if it is a Xorg issue. I looked at xorg logs, but didn't notice anything indicating an error. I know I am not providing a lot of info, but I am not sure where (e.g. which log files) I should seek for more info.

  - by Matheus

  I'm having a trouble when trying to install Skype on my Ubuntu 12.04.1 x64. My notebook have compatible hardware with Ubuntu. My previous OS installed on this machine was the Ubuntu 12.04 x64 and Skype was working great, but I got a formatation and I installed the New ubuntu 12.04.1.

Something like i have the skype-bin package missing (or broken). I can't find it on Software center. I tried to install it by downloading a deb package with the skype-bin package but it ask for a lot another packages! I tried install the .deb package from the official Skype site, but I got the same error! Any Help? Sorry about my bad English, I'm Brazilian

• VS2010 changes your ASP.NET Version on setup projects to 4 - regardless

  - by blomqvist

  When converting your projects to VS2010 you get the question to migrate them to .net4. But even if you do not do that VS set the ASP.NET version to 4 for setup projects. And then when you try to install your application on a machine that does not have .NET 4 installed you will get the error message: “Could not open key: Software\Microsoft\ASP.NET\4.0.30128.0. Verify that you have sufficient access to that key, or contact your support personnel” What you need to do is to change the ASP.NET version back to 2.0 if that is what you want to use. You do that in the properties of the setup project.

• No analog audio in 13.10

  - by danepowell

  I've installed 13.10 on a machine that was previously running Windows 8, and audio output isn't working out of the box. It worked fine in Windows, and the speakers work fine when hooked up to a laptop, so it must an incompatibility between Ubuntu and the motherboard. If I go to sound settings, "Built-in Audio" is selected (SPDIF is also available). This is an Intel Z77 motherboard with an integrated Creative CA0132 sound chipset. I've tried booting a live image of 13.10 (to check for a corrupt install), and the same problem exists. If I boot a live image of 13.04, the only audio output listed in sound settings is a "dummy" card. I've already tried basic troubleshooting steps, such as removing pulseaudio config directories, force-restarting alsa, and making sure the speakers aren't muted in the alsa mixer. At this point, I'm totally stumped :(

• Languages and tools that are "portable" (work well from a USB storage drive) [closed]

  - by CodexArcanum

  I'm a huge fan of running programs from my portable hard drive: it means I always have my favorite tools no matter what computer I'm on. Sadly, development tools seem to be hard to get portable at times. I recently realized that the "portable" version of MinGW I was using off my USB drive was actually interfering with a locally installed version of MinGW, so sometimes even the tools you think are portable, aren't. So what are the best portable development tools that you've used? What runs well on a portable media, leaves the host machine clean, and generally makes moving around easier for you?

• VirtualBox VERR_ACCESS_DENIED for Ubuntu 11.10

  - by kaspnord

  I installed Ubuntu 11.10 on VBox. The VBox settings I use have been tried and proven for countless other installs I have done in the past. Those are still up and running. On my latest install of Ubuntu 11.10 on Vbox, things were working well in the initially - I installed Guest Additions and everything was fine. All of a sudden (I was just moving my mouse), I get an accessed denied error that freezes my entire Ubuntu environment. I close the virtual machine and restart it, but now I keep getting this error message: Any help would be greatly appreciated.

• Setting up fastcgi on an Ubunutu server (socket file permissions issue)

  - by gray alien

  I am trying to set up mod_fcgid on my server. Part of the requirement is that Apache needs to create a socket file for mod_fcgid. I specified the folder for Apache to write the socket data to: /var/run/apache2/fcgid I then specified this file in my fcgid.conf file as follows: SocketPath /var/run/apache2/fcgid/sock I then changed the owner of the folder to www-data (the apache user) and gave the owner full permissions to the folder and its contents. I was able to run my test fcgi app then. When I rebooted the machine, y fastcgi app no longer worked. After some investigation, I found that ownership of /var/run/apache2/fcgid has been reset to root, and with permission reset to 700 I have the following questions: Is there something specific about the /var/run folder? why is the permissions being reset after a reboot? Should I move my socket file to another location (in case root automatically takes ownership of contents in this folder for security reasons?) I am running Ubuntu 10.0.4 LTS 64 bit

• Google Chrome Browser does not display the images from Local network or local host? [migrated]

  - by Arjang

  While developing and testing a site on local network I have noticed that while IE/FireFox would display the images coming from URL's like "http:\mypc" or "http:\localhost" or ip adress on the netwrok , google chrome on Galaxy, Windows Machine, or google Android will not display the images. After having burned too many hours trying various CSS, image src tag, html document description tricks, I have given up. During my search I found (and lost) the link to chrome forums regarding this issue that seemed to say it is just so by users. Anyone has any more information on weather it is possible to view images on local host/computer name on netwrok or ip adress?

• disable password prompt on user switch?

  - by matthewn

  I've got 11.10 on a desktop machine with two users. Both users have "Password" set to "Not asked on login" in Users Settings. At startup, either user can log in without a password. But once both users are logged in, it takes a password to switch between users. In previous Ubuntus, you could override this by setting /desktop/gnome/lockdown/disable_lock_screen to True in gconf-editor. That is ignored in the Gnome 3 / Unity era. Does anyone know a way to disable the password prompt when switching between users in Oneiric?

• Cannot boot: "No init found. Try passing init=bootarg"

  - by glutz

  After losing power, my machine rebooted to this error: “error: no init found. Try passing init=bootarg” Per similar threads on this site and others, I've tried booting from a CD and selecting "Try Ubuntu". Then open a terminal and typing: sudo fsck-y /dev/sda1. The response is: Device or resource busy while trying to open /dev/sda1. Filesystem mounted or opened exclusively by another program? This is on Ubuntu 10.10. Any ideas on what I can try next?

• What is the preferred/recommend way of running two version of ubuntu side by side

  - by GreyGeek

  I am running 14.04, but I need to run some corporate software/scripts that have been specifically designed for 12.04. I am aware of virtual box/vmware for full virtualization but I am looking for something more lightweight (on my windows machine both come at a significant cost in battery life) closer to os virtualization level. Ideally, I would like something like windows 7/8 compatibility mode: the ability to run a program as if I were on 12.04. Does Ubuntu/Linux have such mechanism? What is the preferred way of running programs/scripts designed for an older version of Ubuntu?

• How to replace avconv with (the real) ffmpeg and have it work right?

  - by u2n

  Anyone know how to install the real, current ffmpeg (not the older version by avconv that comes w/ Ubuntu) without having the problems mentioned here? Reasons: Everything works (or so many have written), Use the new syntax, and After some research -- and without getting into the controversy -- I simply believe the packagers made a mistake going with avconv. This is a fix. Apparently this isn't as easy as it should be due to versioning conflicts, and that avconv and ffmpeg can't coexist on the same machine (noted in the above post). Though at least one guide mentions installing ffmpeg locally (~) to achieve coexistence. My release is Precise 12.04.3 LTS, but it appears this would apply to newer ones also.

• Ubuntu 12.04 with Intel 82845g/gl graphics card

  - by user209461

  I have an old machine with the intel card in the title installed. I'd really need to install Ubuntu 12.04 on it, but that's not just possible since the intel drivers don't work properly. So no video acceleration, no window decorations, and lots of other issues. I do know it's an obsolete unsupported card (see Which version of Ubuntu will work out of the box on Intel 82845G Board?) but I think I read somewhere that there had been progress as of late with the latest intel drivers. My question is: is there anything I can currently do to make this card work or should I just give up on the idea and turn to lighter DE like LXDE or XFCE? Thanks

• What would be topic for research in on edge of multiple processors / computers programming?

  - by Kabumbus

  I mean what is not already there? What can be developed in fiew month and give a breakthrue/ start a new leap in science of f multiple computers programming? What i see is already there MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging LAN / wire and other infrastractural cabels for connecting Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

• Your favorite LiveCD

  - by sova

  Perhaps this is a question better suited for linux.se but since I have servers on all environments I was wondering what your favorite LiveCD is. Wiki defines this, for those unfamiliar, as a CD or DVD containing a bootable computer operating system. Live CDs are unique in that they have the ability to run a complete, modern operating system on a computer lacking mutable secondary storage, such as a hard disk drive. Live USB flash drives are similar to live CDs, but often have the added functionality of automatically and transparently writing changes back to their bootable medium. I tend to stick with Knoppix, and today I have to register the machine on the network before I can get any of my utilities running via IP. Any suggestions?

  Tried to install WUBI through Google Chrome on my Vista machine. Got through the usual warning about running new software, selected "continue" and waited for a prompt about where to install WUBI. Never got one...waited about 30 minutes (computer still running fine)...decided to reboot and try again. OOOOOPS. Was not able to reboot Vista. Ouch. When I run a Vista recovery CD it tells me there is an "X:" drive on what used to be my C: drive and it cannot find a Vista install to recover. Anyone seen this ? It is making me very happy... THANKS!!!!!!!!!!!!
