• "Unmet Dependencies" problem when trying apt-get install

  - by GChorn

  Anytime I try to install python packages using the command: sudo apt-get install python-package I get the following output: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: linux-headers-generic : Depends: linux-headers-3.2.0-36-generic but it is not going to be installed linux-headers-generic-pae : Depends: linux-headers-3.2.0-36-generic-pae but it is not going to be installed linux-image-generic : Depends: linux-image-3.2.0-36-generic but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). This seems to have started when these same three packages showed up in Ubuntu's Update Manager and kicked an error when I tried to install them there. Based on the suggestion in the output above, I tried running: sudo apt-get -f install But this only gave me several instances of the following error: dpkg: error processing /var/cache/apt/archives/linux-image-3.2.0-36-generic_3.2.0-36.57_i386.deb (--unpack): unable to create `/lib/modules/3.2.0-36-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko.dpkg-new' (while processing `./lib/modules/3.2.0-36-generic/kernel/drivers/net/wireless/ath/carl9170/carl9170.ko'): No space left on device Now maybe I'm way off-base here, but I'm wondering if the error could be coming from the "No space left on device" part? The thing is, I'm running Ubuntu as a VirtualBox VM but I've got it set to dynamically increase its virtual hard drive space as needed, so why am I still getting this error? Here's my output when I use dh -f: Filesystem Size Used Avail Use% Mounted on /dev/sda1 6.9G 5.7G 869M 88% / udev 494M 4.0K 494M 1% /dev tmpfs 201M 784K 200M 1% /run none 5.0M 0 5.0M 0% /run/lock none 501M 76K 501M 1% /run/shm VB_Shared_Folder 466G 271G 195G 59% /media/sf_VB_Shared_Folder When I perform sudo apt-get -f install and the system says, After this operation, 192 MB of additional disk space will be used. Does that mean 192 MB of my virtual machine's current memory, or 192 MB on top of the rest of my free space? As I said, my machine normally dynamically allocates additional memory from the host machine, so I don't see why there would be memory restrictions at all...

• How do I install Kodos in 12.10?

  - by Brutus

  In previous Ubuntu version I used Kodos extensively. But the package has been dropped in 12.10. It's a neat regular expression testing tool. It's hard to find an alternative that is not Windows only (or Air, or uses action script which bails on more complicated RegEx, or works in Wine - well kinda, but not really..., etc.). So I tried to install Kodos from source, which seems to work (download sourceball and setup.py) but it won't run because of missing PyQT dependencies (that I can't manage to fulfill with anything install-able trough standard packages). I then tried to install PyQT manually (which seems to require manual install of SIP and QT too) and instead of pip I have to use configure.py and qmake. It throws error after error at me. I tried to overcome one after another for over an hour but no luck. It even managed to break Calibre and Music Brains Picard. So I purged all the stuff, reinstalled python-sipand python-qt4 from the standard packages and gave up. Has anyone managed to get Kodos running on 12.10? Or any hints on how to do it?

• Alternatives to PHP [closed]

  - by kaz

  We are starting a project, which goal is to create new frontend interface to our product. Old version was created in PHP, very poorly written. We are choosing the language and frameworks that we want to use in new version. Requirements: New interface will be communicating with API. Application will not have it's own database. We don't have a big team, 3 max programmers for entire project. The main programmers are PHP veterans and knows some other technologies (Rails, C, C++, some Java) but not in professional level. But overall they are good and experienced programmers. So: We want to find a good alternative to PHP. I like Rails very much, but whole ActiveRecord model will be useless, when using application API. Java needs a lot of configuration and someone who is expert in Java to properly run this project. Also, in Java there are a lot of big and complicated enterprise frameworks - not very good for 2-3 programmers team. Python - I don't know Python and don't know good and experienced programmers who knows PY - but it's not so complicated and big as Java and maybe in long period it's good alternative for PHP. What are your thoughts?

• Social Network ( Help) [on hold]

  - by brunocascio

  I am in a great "problem" so to speak , and I need opinions to decide. The problem is to create a social network without knowing the number of users who use it (but if thinking if they were sufficient ) . The question is which language and framework to use .... I do not mind having to learn new technologies and / or languages ??. I am among PHP ( Laravel - Symfony - other? ) Ruby ( Ruby on Rails 4? ) Javascript ( Ember , express, locomotive , other? ) Python ( Django ) Java ( Grails , Play, other?) I have experience in both PHP and frameworks. In Symfony developed part of it, but I got tired having to do a thousand configurations for all . I know very little about Ruby , but I saw very easy . I do not know are saying the performance. Javascript costs me to get used to their paradigm , and do not know if at all sure to cover everything with Javascript. Django and python ( very poor knowledge ) Java , experience in data structure and android , but not web . Regarding the / s databases: In my head I have to MongoDB and costs change of opinion by another database with respect to documentation and EASE performance . But .......... frameworks have no support at all clear . I also thought of mixing technologies for using a tecnlogía backend and the frontend other. As I read in the new social network Origo . They use Symfony for REST and javascript for the frontend . ( Backbone , Underscore and RequireJS ) What do you recommend me ?

• Hosting Mercurial on IIS7

  - by Lasse V. Karlsen

  Note, this might perhaps be best suited on serverfault.com, but since it is about hosting a programmer source code repository, I am not entirely sure. I'm posting here first, trusting that it'll be migrated if necessary. I'm attempting to host clones of my Mercurial repositories on my own server (I have the main repo somewhere else), and I'm attempting to set up Mercurial under IIS. I followed the guide here, but I get an error message. Solved: See bottom of this question for details. The error message is: mercurial.error.RepoError: repository /path/to/repo/or/config not found Here's what I did. I installed Mercurial 1.5.2 I created c:\inetpub\hg I downloaded the hg source as per the instructions of the webpage, and copied the hgweb.cgi file into c:\inetpub\hg (note, the webpage says hgwebdir.cgi, but this particular file does not exist, hgweb.cgi does, however, can this be the source of the problem?) I added a hgweb.config, with the following contents: [paths] repo1 = C:/hg/** [web] style = monoblue I created c:\hg, created a sub-directory test, and created a repository inside it I installed python 2.6.5, latest 2.6 version from the website (the webpage mentions I need to install the correct version or I'll get a specific error message, since I don't get an error message that looks remotely like the one mentioned, I assume that 2.6.5 is not the problem) I added a new virtual host hg.vkarlsen.no, pointing it to c:\inetpub\hg For this host, I added a script mapping under the Handler Mappings section, mapping *.cgi to c:\python26\python.exe -u %s %s as per the instructions on the website. I then tested it by navigating to http://hg.vkarlsen.no/hgweb.cgi, but I get an error message. To make it easier to test, I dropped to a command prompt, navigated to c:\inetpub\hg, and executed the following command (error message is part of the text below): C:\inetpub\hg>c:\python26\python.exe -u hgweb.cgi Traceback (most recent call last): File "hgweb.cgi", line 16, in <module> application = hgweb(config) File "mercurial\hgweb\__init__.pyc", line 12, in hgweb File "mercurial\hgweb\hgweb_mod.pyc", line 30, in __init__ File "mercurial\hg.pyc", line 82, in repository File "mercurial\localrepo.pyc", line 2221, in instance File "mercurial\localrepo.pyc", line 62, in __init__ mercurial.error.RepoError: repository /path/to/repo/or/config not found Does anyone know what I need to look at in order to fix this? Edit: Ok, I think I managed to get one step closer to the solution, but I'm still stumped. I realized the .cgi file is a python script file, and not something compile, so I opened it for editing, and these lines was sitting in it: # Path to repo or hgweb config to serve (see 'hg help hgweb') config = "/path/to/repo/or/config" So this was my source for the specific error message. If I change the line to this: config = "c:\\hg\\test" Then I can navigate the empty repository through the Mercurial web interface. However, I want to host multiple repositories, and seeing as the line says that I can also link to a hgweb config file, I tried this: config = "c:\\inetpub\\hg\\hgweb.config" But then I get the following error message: mercurial.error.Abort: c:\inetpub\hg\hgweb.config: not a Mercurial bundle file Exception ImportError: 'No module named shutil' in <bound method bundlerepository.__del__ of <mercurial.bundlerepo.bundlerepository object at 0x0260A110>> ignored Nothing I've tried for the config variable seems to work: config = "hgweb.config" config = "c:\\hg\\hgweb.config" various other variations I don't remember. So, still stumped, pointers anyone? Solved: I ended up having to edit the hgweb.cgi file: from: from mercurial.hgweb import hgweb, wsgicgi application = hgweb(config) to: from mercurial.hgweb import hgweb, hgwebdir, wsgicgi application = hgwebdir(config) Note the added hgwebdir parts there. Here's my hgweb.config file, located in the same directory as hgweb.cgi file: [collections] C:/hg/ = C:/hg/ [web] style = gitweb This now serves my repositories successfully. Hopefully this question will give others some information if they're stumped as I was.

• What are the Open Source alternatives to WPF/XAML?

  - by Evan Plaice

  If we've learned anything from HTML/CSS it's that, declarative languages (like XML) work best to describe User Interfaces because: It's easy to build code preprocessors that can template the code effectively. The code is in a well defined well structured (ideally) format so it's easy to parse. The technology to effectively parse or crawl an XML based source file already exists. The UIs scripted code becomes much simpler and easier to understand. It simple enough that designers are able to design the interface themselves. Programmers suck at creating UIs so it should be made easy enough for designers. I recently took a look at the meat of a WPF application (ie. the XAML) and it looks surprisingly familiar to the declarative language style used in HTML. It's apparent to me that the current state of desktop UI development is largely fractionalized, otherwise there wouldn't be so much duplicated effort in the domain of graphical user interface design (IE. GTK, XUL, Qt, Winforms, WPF, etc). There are 45 GUI platforms for Python alone It's seems reasonable to me that there should be a general purpose, open source, standardized, platform independent, markup language for designing desktop GUIs. Much like what the W3C made HTML/CSS into. WPF, or more specifically XAML seems like a pretty likely step in the right direction. Now that the 'browser wars' are over should we look forward to a future of 'desktop gui wars?' Note: This topic is relatively subjective in the attempt to be 'future-thinking.' I think that desktop GUI development in its current state sucks ((really)hard) and, even though WPF is still in it's infancy, it presents a likely solution to the problem. Update: Thanks a lot for the info, keep it comin'. Here's are the options I've gathered from the comments and answers. GladeXML Editor: Glade Interface Designer OS Platforms: All GUI Platform: GTK+ Languages: C (libglade), C++, C# (Glade#), Python, Ada, Pike, Perl, PHP, Eiffel, Ruby XRC (XML Resource) Editors: wxGlade, XRCed, wxDesigner, DialogBlocks (non-free) OS Platforms: All GUI Platform: wxWidgets Languages: C++, Python (wxPython), Perl (wxPerl), .NET (wx.NET) XML based formats that are either not free, not cross-platform, or language specific XUL Editor: Any basic text editor OS Platforms: Any OS running a browser that supports XUL GUI Platform: Gecko Engine? Languages: C++, Python, Ruby as plugin languages not base languages Note: I'm not sure if XUL deserves mentioning in this list because it's less of a desktop GUI language and more of a make-webapps-run-on-the-desktop language. Plus, it requires a browser to run. IE, it's 'DHTML for the desktop.' CookSwing Editor: Eclipse via WindowBuilder, NetBeans 5.0 (non-free) via Swing GUI Builder aka Matisse OS Platforms: All GUI Platform: Java Languages: Java only XAML (Moonlight) Editor: MonoDevelop OS Platforms: Linux and other Unix/X11 based OSes only GUI Platforms: GTK+ Languages: .NET Note: XAML is not a pure Open Source format because Microsoft controls its terms of use including the right to change the terms at any time. Moonlight can not legally be made to run on Windows or Mac. In addition, the only platform that is exempt from legal action is Novell. See this for a full description of what I mean.

• CPU fan kicks in to full gear when i try to install ubuntu 12.10 or LTS

  Whenever I try to install (DUAL BOOT WITH WINDOWS 7) both versions of Ubuntu desktop on my PC the CPU fan starts spinning so fast that I couldn't even go through the installation for fear of my CPU exploding. In windows 7, the temp reaches 25-30 idle and 30-45 under full load. I tried installing through Wubi and by burning it to USB drive. Both wield the same results. I would appreciate any help.

• Helping install mrcwa and solve problems with f2py in Ubuntu 14.04 LTS

  - by user288160

  I am sorry if this is the wrong section but I am starting to get desperate, please someone help me... I need to install the program mrcwa-20080820 (sourceforge.net/projects/mrcwa/) because a summer project that I am involved.

• Best Practices For Database Consolidation On Exadata - New Whitepapers

  - by Javier Puerta

   Best Practices For Database Consolidation On Exadata Database Machine (Nov. 2011) Consolidation can minimize idle resources, maximize efficiency, and lower costs when you host multiple schemas, applications or databases on a target system. Consolidation is a core enabler for deploying Oracle database on public and private clouds.This paper provides the Exadata Database Machine (Exadata) consolidation best practices to setup and manage systems and applications for maximum stability and availability:Download here Oracle Exadata Database Machine Consolidation: Segregating Databases and Roles (Sep. 2011) This paper is focused on the aspects of segregating databases from each other in a platform consolidation environment on an Oracle Exadata Database Machine. Platform consolidation is the consolidation of multiple databases on to a single Oracle Exadata Database Machine. When multiple databases are consolidated on a single Database Machine, it may be necessary to isolate certain database components or functions in order to meet business requirements and provide best practices for a secure consolidation. In this paper we outline the use of Oracle Exadata database-scoped security to securely separate database management and provide a detailed case study that illustrates the best practices.

• Fan always spinning on Maverick

  - by jb

  I use Dell Studio 1555, after update to maverick my fan started spinning full speed allways. I use xserver-xorg-video-ati/radeon drivers because fglrx messes with my desktop resolution when connecting external screen. Processor is mostly idle. U use some desktop effects. On the same configuration on Lucid my fan worked slower. It eats lots of battery time :( Bug filed: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/675156 Any insights how to solve/debug it or work around it?

• Notebook MSI GT640 - noisy fan - Ubuntu 11.10 x64

  - by pablo

  I have all time this issue when using Ubuntus, the fan (fans?) runs most off the time and between 60%~100% even in idle which is weird. The GPU temperatures are mostly around 80 degrees and I don't think it's right :( I always use Jupiter with power saving preset and add the line in linux default like this: quiet splash pcie_aspm=force i915.i915_enable_rc6=1 So it helps a little (fan just doesn't run all the time 100%...) What else can I do? The notebook spec is: Core i7-720 (8 threads) NVIDIA GTS250M So it's rather one of the first, not so silent and cold notebooks;), with Core i7 family and without optimus technology (as nvidia GPU is the only graphic card built-in) but anyway I don't have theese strange hot times in Windows 7.

  I am trying to print to a samba printer via CUPS. I have configured the printer allright, but there seems to be a problem with authentication. The error message I get is Session setup failed: NT_STATUS_LOGON_FAILURE The GUI also tells me: Idle - Tree connect failed (NT_STATUS_ACCESS_DENIED) It used to work with previous versions of CUPS (1.4.3 and 1.4.6) under Ubuntu 11.04 I am doing this on a clean install of Ubuntu 12.04, CUPS version 1.5.3.

• "sudo cd ..." one-liner?

  - by j-g-faustus

  Occasionally I want to cd into a directory where my user does not have permission, so I resort to sudo. The obvious command sudo cd somedir doesn't work: $ sudo mkdir test $ sudo chmod go-rxw test $ ls -l drwx------ 2 root root [...snip...] test $ cd test -bash: cd: test: Permission denied $ sudo cd test sudo: cd: command not found Using sudo su works: $ sudo su # cd test Is it possible to make this into a one-liner? (Not a big deal, just idle curiosity :) The variations I tried didn't work: $ sudo "cd test" sudo: cd: command not found $ sudo -i cd test -bash: line 0: cd: test: No such file or directory $ sudo -s cd test The last one doesn't give an error, but it cd's within a new shell that exits by the end of the line, so it doesn't actually take me anywhere. Can someone enlighten me as to why this happens? Why is sudo cd not found, when for example sudo ls ... works fine?

• Atheros AR8132 Ethernet refuses to connect after suspend

• Power & Sleep Management

  - by Espressofa

  I'm running 12.10 with xmonad. Trying to ensure that the right things happen when I close laptop lid, etc. I see Internet search results for similar issues that mostly point towards gnome-power-manager. I have the package installed, but gnome-power-manager is not in my path anywhere. The behavior I'm looking for is as following: Sleep on lid close Awaken on lid open Turn off screen after 10 idle minutes Most importantly, have better battery life. I'm supposed to be getting 9 hours and I haven't seen the battery life estimate above 2.5 hours yet. Any tips on where to look or how to configure this would be much appreciated.

• Installation stops at a black screen on a Dell XPS 15z

  - by user780610

  This is my first time trying to install a Linux distro, and I'm having a bit of a time with it. I've tried to install Ubuntu on my new Dell XPS 15z using the Wubi Windows installer (on x64 Windows 7 Pro) and I've also tried mounting the ISO to a USB drive as explained on ubuntu.com. Unfortunately, both methods hit the same problem: after some text stuff, the screen turns off. I still have control over things like keyboard brightness, so it's not that the computer's going idle or anything like that. Any ideas?

• Fn keys for Brightness not working on Toshiba Satellite L755

  - by JAMES PARENTE

  I am running Ubuntu 12.04 and I love it! The only problem is the keys for my brightness, F6 and F7, does not work when I am on battery power or AC power. It randomly works after I am idle for a while and log back in. The other weird thing is to see my battery indicator, I need to toggle my touch pad button that is right above the actual pad on and off for it to show up, and then back on so I can use my touch pad, obviously. The only other Fn buttons that work on my laptop is the button to mute (F1) Touch pad on and off (F9) and Fn+3 and Fn+4 for my volume. The only Fn buttons that I care if they work again are my brightness, which again, are F6 and F7. Thanks! James

• How can I lower the CPU temperature?

  - by nmc

  I have installed Ubuntu 12.04 on my EeePC 1015PX and I've noticed that the CPU temperature does not go below 60ºC (70 is usual). Looking at powertop it seems the 2 cores (Atom N570) are idle most of the time. I've installed jupiter (w/ jupiter-eee-support) but it did not help. Edit: Meanwhile I've found out that echo 2 > /sys/devices/platform/eeepc-wmi/cpufv is supposed to turn on Super Hybrid Engine. Though it seems to help a bit (temperature goes down 2-3ºC), the temperatures are still in the 60-70ºc range.

• How to totaly remove blank screen screensaver?

  - by Xamidovic

  I have no screensaver installed but when I watch movies after a while blank screen comes and I have to get up every time and move mouse to continue watching the movie. It really pisses me off. I found this command "gsettings set org.gnome.desktop.screensaver idle-activation-enabled false" which allegedly disables blank screen... I put that command in once, and blank screen keeps doing its crap. I did it again, blank screen still works on its own and would not stop. Did it trice, and nothing. Please someone help me with this, I'm freaking out when trying to watch a decent movie. I'd have to mention that I once had "xscreensaver" installed but I removed it after awhile. Don't know if it has something to do with blank screen still work, maybe some else would know. PLEASE HELP !

• Ubuntu 12.10 "Turn screen off when inactive for: Never" still turns off

  - by Will

  After a fresh install of Ubuntu 12.10, my screen still goes off after about ten minutes. I've been to the Brightness and Lock control panel. The Turn screen off when inactive for: setting is set for Never. I've been through the dconf Editor searching for power, screen, and idle changing parameters. This doesn't seem to have any effect on the display timeout. Here's one more interesting thing, the screen doesn't go off, per se. It just goes black. Meaning, the back lighting is still on, and all the pixels are black. When it goes black, it does a very pleasant quick dim to black. Similarly, it quickly un-dim's after a key press, mouse movement, or mouse click. So, I'm feeling this is more of a software setting the timeout, not a power saving function.
