• Unstable wireless connection on Ubuntu only (router config problem?)

  - by crunch

  so I'm using Ubuntu 14.04 and I could connect to all Wi-Fi's that I've tried and it worked fine... Except for this router that I have at home. This connection seems to be unstable, it just randomly disconnects and reconnects. On the same machine I have Ubuntu 13.10 (same problem) and Windows 8 (no problem). Also there are no Wi-Fi problems when I connect with my Android phone. So I figured it must be some config issue. I tried tweaking some settings/restoring default on the router but I don't really know what I'm doing so, unsurprisingly, it didn't fix the problem.

• I Can't update 12.04 to 12.10 ERROR:"gpg: WARNING: This key is not certified with a trusted signature!"

  - by jason328

  I'm trying to update to 12.10 from a 12.04 machine. When I ran the code sudo do-release-upgrade -d in my terminal and verified my password it checked for a new upgrade. I was then returned with this: gpg: Good signature from "Ubuntu Archive Automatic Signing Key <[email protected]>" gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.` There of course is more but it looks like it may or may not be showing private information with it. What's causing this and how do I fix this.

• How do you configure mupen64plus controls?

  - by user99426

  I installed mupen64plus from the repositories using Synaptic. I like the emulator (for the most part, a couple of graphics glitches on TLOZ Ocarina of Time), especially its performance on my old machine, but I cannot figure out how to configure the controls for myself. I tried looking at Google Code's guide here but I can't find the file I need to edit and the link with the key ids isn't working, so even if I could find the file I wouldn't be able to change anything. So what I need is a resource with the key ids and where to find the file I need to edit. I am running Ubuntu 12.10 32-bit. 2GB RAM, Intel CORE 2 DUO @ 2.00GHz

• Managed servers getting down regularly by Node Manager. WAD?

  - by csoto

  Recently I have been working on a service request where several instances were running, and several technologies were being used, including SOA, BAM, BPEL and others. At a first glance, this may seem to be a Node Manager problem. But on this situation, the problem was at JMS - Persistent Store level. Node Manager can automatically restart Managed Servers that have the "failed" health state, or have shut down unexpectedly due to a system crash or reboot. As a matter of fact, from the provided log files it was clear that the instance was becoming unhealthy because of a persist6ent Store problem. So finally, the problem here was not with Node Manager as it was working as designed, and the restart was being caused by the Persistent Store. After this Persistent Store problem was fixed, everuthing went fine. This particular issue that I worked was on an Exalogic machine, but note that this may happen on any hardware running Weblogic.

• Bluetooth Audio and SoftPhone Audio Input/Output

  - by o7th Web Design

  I have a Voip Softphone software that I would like to start using on my Ubuntu 14.04 box. Here's the thing. My system sound right now goes through my HDMI to my speaker system so I can play music all day ;-) I have a bluetooth headset connected to the machine as well. What I am wondering is if there is a way to: Auto-mute the music when a call comes in Auto-switch the sound devices when a call comes in, from my hdmi sound device, to my headset Auto-switch back when the call ends, and auto-un-mute the music Or even just an auto-switch to the headset? I can always pause the music ;)

• Install/Downgrade kernel to v3.5.5 on Ubuntu 13.04

  - by Villi Magg

  I've been looking around the internet for a solution to downgrade the kernel from 3.8 to 3.5.5 since I've got the AMD/Ati Radeon Mobility HD 5600 graphic card on my machine. This video card in unfortunately not supported by the 3.8 kernel. And then when I've downgraded the kernel I need to install a version 12.* of the AMD Catalyst driver. There is too much in stake to wipe out the current installation of the OS and install an older OS. So I would like to avoid doing that to the ends of the world. Hope someone can help me with this one? Kind regards! Villi Magg.

• Problems after installing Ubuntu LiveUSB on my 2nd HD

  - by user113106

  I decided to create a Ubuntu USB installer using the Universal USB Installer, selecting a Ubuntu 12.10 ISO. I selected my D: drive, my NON-windows7 carrying drive as install. After this I Re-booted my system and my PC began to Run the Ubuntu Boot-startscreen every time I power up the machine, giving errors like this: Root=Unknown I used my girlfriend's laptop to create, on the exact same way, a real! USB Ubuntu installer. Booting from that USB, picking the option Run Ubuntu from this USB I get the following error: http://postimage.org/image/63qkv98c1/ Let's try installing it from that USB to a Hard-Disk: http://postimage.org/image/usqbwymfx/ As I said: I do not have the Option to pick my Boot-section, at this very moment I can only access to the Ubuntu installation and nothing else. I've read about 90% of other Questions that could've been related, but I could not find a solution. BTW I'm running a Acer Aspire 2Quadcore 4gb DDR 2 Ati Radeon HD, 64bit and I've set my Bios OS-usage from Windows to "Others"

• How do I change local display resolution via SSH?

  - by krumble1

  I have a machine running Ubuntu Server 12.04 LTS and I'm having problems with the local monitor. The Dell flat panel I'm using only displays this message while the computer running: "Cannot Display This Video Mode" and then the information: "Optimum resolution 1280x1024 60Hz". I'm fairly new to using an operating system wholly via command line but I'm learning fast. :) I can access the server fine via SSH so using it is not a problem. However, for where it is positioned at the moment, it would be much more convenient to use the computer locally. I'm just wondering how to change the local screen resolution via SSH to something usable by my monitor. Thanks for your time! BTW: I have also tried switching displays and I still have the same problem. Also BTW: I tried putting in the xrandr command and all I get back is: Can't open display

• dpkg --set-selections from 11.10 on 12.04LTS

  - by Vixxo

  I have to move a server to a different DC in a different country. The server is currently running 11.10, but the new fresh installed OS will be 12.04. The hardware of both is completely different. In order to install the same packages that the server currently uses, I am thinking of exporting all packages to a list and then run this list on the new machine. I will after that proceed with transferring the configuration files for the LAMP stack. My question is if this will work, or if there will be a problem because of the differences in the versions of the OS? What is the correct way to do it? PS. I have no access to KVM to reload the OS as an image, so this would not be an option.

• Can exim be configured to send all emails externally?

  - by Tom Brossman

  How do I configure exim4 to route all emails via a third-party SMTP server when the sender's domain, recipient's domain, and server hostname all match? I followed this great answer and have exim4 sending emails to addresses at other domains tested and working from an Ubuntu server. My only issue is that emails where both the sender and recipient share the same domain as the server hostname, they never leave the server (and this is the expected behavior). For example, sending from [email protected] -- [email protected] works fine, but sending from [email protected] -- [email protected] just routes the mail locally to /var/mail/account2, without passing through the third-party SMTP server. I'm using Google Apps at my own domain and want to send emails from [email protected] to [email protected] from a machine with the hostname example.com. I want to route them through Google's SMTP server so I see them in my other email clients. Is this possible? Very similar questions (but for postfix) here and here.

• Why are PPA's designed for only latest version?

  - by user210108

  Why are PPA's set to only retain the latest version of the software? I ask because I just installed Blender 2.69 and it constantly crashes on me; I then decided to just install 2.68a but found that it is IMPOSSIBLE to install an older version of software using the Ubuntu software center. I turned to possibly seeing if the PPA retained an older version but have found most PPA's remove older versions as they are designed to only offer the latest. How does this sound like a good idea? What if, for example, someone releases a version of their software that constantly crashes and the user wishes to get an older version but because the way PPA's are designed they cannot. Sounds familiar... To add insult to injury, I was easily able to role back Internet Explorer to version 9 on a machine at work today; that is just sad.

• Why is Prolog associated with Natural Language Processing?

  - by kyphos

  I have recently started learning about NLP with python, and NLP seems to be based mostly on statistics/machine-learning. What does a logic programming language bring to the table with respect to NLP? Is the declarative nature of prolog used to define grammars? Is it used to define associations between words? That is, somehow mine logical relationships between words (this I imagine would be pretty hard to do)? Any examples of what prolog uniquely brings to NLP would be highly appreciated.

• Paraview 3.98.1 takes too long to launch

  - by Alejo

  I have been used Ubuntu 12.10 with paraview 3.14.1 to run and visualise CFD simulations (OpenFoam and Eilmer3) and the experience has been really good up to date. When I wanted to try Ubuntu 13.01, I realised paraview 3.98.1 was the version to be installed in this distribution when running sudo apt-get install paraview. I noticed it takes way too long to launch, not to mention that paraFoam always produces an error so paraFoam -bulitin has to be used instead. Does anyone know the reason why paraview 3.98.1 takes so long to load?, is it because the new version has more feautures or Ubuntu 13.04 simply can't handle it smoother? My machine is a Thinkpad W530 with 16GB RAM 1600MHz and intel i7-3720QM. I am running Ubuntu under VMware player set-up with 4GB RAM, 2 cores and Automatic vitualization. Thanks.

• ASP.NET: Including JavaScript libraries conditionally from CDN

  - by DigiMortal

  When developing cloud applications it is still useful to build them so they can run also on local machine without network connection. One thing you use from CDN when in cloud and from app folder when not connected are common JavaScript libraries. In this posting I will show you how to add support for local and CDN script stores to your ASP.NET MVC web application. Our solution is simple. We will add new configuration setting to our web.config file (including cloud transform file of it) and new property to our web application. In master page where scripts are included we will include scripts from CDN conditionally. There is nothing complex, all changes we make are simple ones. 1. Adding new property to web application Although I am using ASP.NET MVC web application these modifications work also very well with ASP.NET Forms. Open Global.asax and add new static property to your application class. public static bool UseCdn {     get     {         var valueString = ConfigurationManager.AppSettings["useCdn"];         bool useCdn;           bool.TryParse(valueString, out useCdn);         return useCdn;     } } If you want less round-trips to configuration data you can keep some nullable boolean in your application class scope and load CDN setting first time it is asked. 2. Adding new configuration setting to web.config By default my application uses local scripts. Although my application runs on cloud I can do a lot of stuff without staging environment in cloud. So by default I don’t have costs on traffic when including scripts from application folders. <appSettings>   <add key="UseCdn" value="false" /> </appSettings> You can also set UseCdn value to true and change it to false when you are not connected to network. 3. Modifying web.config cloud transform I have special configuration for my solution that I use when deploying my web application to cloud. This configuration is called Cloud and transform for this configuration is located in web.cloud.config. To make application using CDN when deployed to cloud we need the following transform. <appSettings>   <add key="UseCdn"        value="true"        xdt:Transform="SetAttributes"        xdt:Locator="Match(key)" /> </appSettings> Now when you publish your application to cloud it uses CDN by default. 4. Including scripts in master pages The last thing we need to change is our master page. My solution is simple. I check if I have to include scripts from CDN and if it is true then I include scripts from there. Otherwise my scripts will be included from application folder. @if (MyWeb.MvcApplication.UseCdn) {     <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.4.min.js" type="text/javascript"></script> } else {     <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> } Although here is only one script shown you can add all your scripts that are also available in some CDN in this if-else block. You are free to include scripts from different CDN services if you need. Conclusion As we saw it was very easy to modify our application to make it use CDN for JavaScript libraries in cloud and local scripts when run on local machine. We made only small changes to our application code, configuration and master pages to get different script sources supported. Our application is now more independent from external sources when we are working on it.

• When profiling a function for time use, what information is desirable?

  - by AaronMcSmooth

  I'm writing a program similar to Python's timeit module. The idea is to time a function by executing it anywhere from 10 to 100,000 times depending on how long it takes and then report results. I've read that the most important number is the minimum execution time because this is the number that best reflects how fast the machine can run the code in question in the absence of other programs competing for processor time and memory. This argument makes sense to me. Would you be happy with this? Would you want to know the average time or the standard deviation? Is there some other measure that you consider more important?

• Best practice to identify and kill hanging process, when system hangs and reacts slowly on user input?

  - by NES

  Recently when I tried to open a video with VLC, my system slowed down, the open applications webbrowser, VLC and filemanager and others didn't react any longer. The mouse just reacted still very slowly. On a windows machine i would press a keycombi CTRL-ALT-DEL to open the taskmanager, search the process which caused the hang and kill it. Since i'm fairly new with the use of linux i haven't figured out the best practice for solve such a situation in Ubuntu. Which quick and effective way would you recommend to identify the hanging process and close it, when the system already reacts very slowly on user input?

• If a company is using ubuntu on its servers/dektops, does it have to pay?

  - by rsjethani

  a friend of my friend has started a small firm and given me the responsibility to erect all the IT infrastructure required? I'm basically a windows guy that too on the developer side. But recently I fell in love with Linux n dared to dream about becoming a Linux admin and play with Linux, virtualization, cloud etc. So, first I'll be running a pilot project of creating mail/ftp/web servers required on a Linux based server. And Ubuntu is the ideal choice for a Linux beginner right? my question is simple: if a commercial organization is using Ubuntu for it's day to day desktop and server(mail,ftp etc) uses but has technicians which can provide support internally then do the organization needs to pay for Ubuntu? If yes then could you please suggest a Debian based distro on the lines of CentOS. Also can I use the Ubuntu 12.04 LTS 64 bit desktop version instead of the no gui server version for the server machine(gui can be helpful for a windows guy like me) thanks.

• What is the point in using real time?

  - by bobobobo

  I understand that using real time frame elapses (which should vary between 16-17ms on average) are provided by a lot of frameworks. GetTimeElapsedSinceLastFrame, and it gives you the wall clock time. But should we use this information in basic physics simulation? It looks to me to be a bad idea. Say there is a slight lag on the machine, for whatever reason (say a virus scanner starts up). The calculations all jump, and there is no need for this. Why not use a virtual second and ignore wall clock time? For gameplay on the level of Commander Keen, shouldn't you always use the virtual second and not real-time? (Besides stopwatch timing for race games) I don't see a need to use real time and not a fixed 16ms time step.

• 12.10 sound resumes only after Suspend

  - by user70716

  I installed the 12.10 yesterday and like 12.04 there was no sound, I have an ACER 4830 TG. I noticed that the HDMI output is working fine, but Speaker or Headphone isn't working. So I did the following: sudo add-apt-repository ppa:ubuntu-audio-dev sudo apt-get update sudo apt-get dist-upgrade and still couldn't get the sound. Then I found the temp fix for this issue which is to Suspend the machine completely and resume. However, after restart the same thing happens. Is there a solution to this issue?

• 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.

• How to hide process arguments from other users?

  - by poolie

  A while ago, I used to use the grsecurity kernel patches, which had an option to hide process arguments from other non-root users. Basically this just made /proc/*/cmdline be mode 0600, and ps handles that properly by showing that the process exists but not its arguments. This is kind of nice if someone on a multiuser machine is running say vi christmas-presents.txt, to use the canonical example. Is there any supported way to do this in Ubuntu, other than by installing a new kernel? (I'm familiar with the technique that lets individual programs alter their argv, but most programs don't do that and anyhow it is racy. This stackoverflow user seems to be asking the same question, but actually just seems very confused.)

• Google web search shows dateCreated instead of dateModified metadata

  - by LonelyPixel

  So today I discovered that the pages from my website are listed with an unexpected date value. I specify the schema.org properties dateCreated and dateModified for most of my content pages. I'd expect that search results show me when a page was last updated, to get a sense of the currency of the page. But it's showing the date of first publishing which may be years ago. That's a bit unsatisfying but I don't want to misuse the metadata because Google probably reads it wrong. Some search terms for you to try it out: "gitrevisiontool"; "easyxml"; "multiselecttreeview" (look for the results on dev.unclassified.de; the human- and machine-readable dates come at the end of the page) Does anybody know more about what's wrong here? Or does it work as designed? (What a stupid design that would be.)
