• Getting wireless to work on Ubuntu 11.10 (on a mac machine)

  - by yayu

  I have a 2008 white 13.3 inch macbook that now solely runs ubuntu. However, I cannot get wifi or cable to work on it. Regarding the cable, it atleast tries to connect but eventually disconnects from the wired network. Here is the output for lspci (pastebin) I tried installing b43-fwcutter and firmware-b43 but get errors. (I loaded them from a thumb drive and tried sudo dpkg -i). I cannot understand these instructions from the documentation, as I cannot locate the pool directory. b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under ../pool/main/p/patch/ or both in the official repositories online. Note: In some versions (10.04 and 11.04 at least) there is not a /pool/main/p/patch/ If this file is missing then you don't need it. In this case you only need to install /pool/main/b/b43-fwcutter by following the instructions below.

• Is C++11 Uniform Initialization a replacement for the old style syntax?

  - by Robert Dailey

  I understand that C++11's uniform initialization solves some syntactical ambiguity in the language, but in a lot of Bjarne Stroustrup's presentations (particularly those during the GoingNative 2012 talks), his examples primarily use this syntax now whenever he is constructing objects. Is it recommended now to use uniform initialization in all cases? What should the general approach be for this new feature as far as coding style goes and general usage? What are some reasons to not use it? Note that in my mind I'm thinking primarily of object construction as my use case, but if there are other scenarios to consider please let me know.

• Openjdk-7-jdk some commands not recognized?

  - by function

  I installed openjdk-7-jdk using apt-get install. However, when I type 'javac', the terminal says, 'bash: /usr/bin/javac: No such file or directory'. I think the link is broken, but how can I fix it? Note: I installed openjdk-7-jdk before, but then I removed openjdk and installed sun-java. Now I deleted sun-jdk and want to go back to openjdk, but javac is not recognized. I'm using Ubuntu 11.10. Edit: Recognized: java; Not Recognized: javac, javadoc, appletviewer, ...

  Hotmail financé par la publicité ciblée ? L'idée ferait son chemin mais sur un modèle différent de celui de G-mail Tim O'Brien, un cadre de Microsoft, vient de participer à une conférence sur les sujets du Cloud et des SaaS (Software as a service), la bien nommée SaaSCon 2010 de Santa Clara, en Californie. A cette occasion, O'Brien a tenu à rappeler que garder et protéger les données de tous les utilisateurs de Hotmail, une des messageries les plus populaires au monde, sur les serveurs de Microsoft était un défi quotidien et sans cesse renouvelé. Il note par ailleurs que le degré de confiance entre les utilisateurs de services hébergés de type Cloud (et donc de Hotmail) et ...

• How do I get Chromium to show PDFs using Evince?

  - by potofcoffee

  Is there any way to get Chromium to use a mozpluggerrc/evince combination to show PDFs embedded into its own window? Right now, Chromium is just downloading PDFs. I can open them in an external evince window by clicking on the downloaded file. I am using Chrome 18.0.1025.168 under Ubuntu 12.04 (amd64). Here's the pdf section of my /etc/mozpluggerrc.d/62-documents.conf: application/pdf:pdf:PDF file application/x-pdf:pdf:PDF file text/pdf:pdf:PDF file text/x-pdf:pdf:PDF file repeat noisy swallow(evince) fill needs_xembed: evince "$file" mozpluggerrc does show up in about:plugins. BTW, this works just fine in Firefox. Note: I am not looking for hints on how to use Google Chrome's PDF plugin in Chromium.

• How do global cancel/exit commands work in bash?

  - by SecurityGate

  As I have done multiple times before, I've written bash scripts, and just general commands that go nowhere. They just blink the little command line cursor at me for infinity until I control+C the command. When I do cancel the command, what exactly is going on when I do this? Am I somehow stopping and killing the current PID I'm working on? Does it jump to a different run-level and execute something to terminate the command? On a slightly different note, I've never been able to figure out how to set up something like this in a script or program I've worked on. Since I mostly program in Ruby, can I setup something like a certain key press stops the program? Every time I've looked into doing something similar, I always end up getting hung up when it comes to user input, whether that is a loop waiting for a condition, or something like this: def Break() user_break = gets.strip end def Main() Function1() Break() Function2() Break() [...] end It seems and is incredibly bulky, and definitely isn't easily scaled up or down.

• Closing lid does not suspend laptop

  - by fgysin

  I'm on a Lenovo T400 laptop. In the past I had suspend problems on every second version of Ubuntu (at least it feels like it), but in 11.04 it was working perfectly. Now, after the upgrade to 11.10 closing the laptop lid does no longer initialize suspension. When I choose 'Suspend' from the shutdown menu it works perfectly, so this does not seem to be an issue with suspend itself. The options in System Settings>Power are of course set to suspend in case of closing the lid (both for battery and AC poer). Note: I have no idea if this is of any importance, but I'm running the gnome-session-fallback stuff, as I just hate the Unity desgin.

• What's the best way to add some particle or laser effects to an already animated character?

  - by Scott

  I just purchased some rigged and animated robot characters from 3drt for a game I'm making in unity. I would like to be able to add some weapon effects to the characters. For example, I would like for the robots to be able to shot lasers out of the hands at enemies. I have know idea where to even start with this task as I'm more of a programmer than a graphics guy. Can some experienced developers / designers please point me in a good direction? Thanks. Note: As of right now I have maya and blender installed on my computer.

• How do you start modding a game without an editor?

  - by Protector one

  I often come across very impressive mods for PC games that don't have an official editor, other development tools or its source code publicly available. (Take this amazing Multiplayer mod for Just Cause 2, for example.) How do you go about creating mods for such games? I'm not talking about replacing the odd texture or 3D model—that sort of thing seems fairly easy given tools to pry them out of game files and put them back in—but more along the lines of adding game behavior. (Tweaking settings files also doesn't count.) Note that I'm not asking "how to create a mod", I just want to know where to start or where to go to learn.

• .NET serait le framework le plus populaire devant GWT, d'après une étude remise en cause par le créa

  .NET serait le framework le plus populaire Devant GWT, d'après une étude remise en cause par le créateur de Rails Evans Data vient de publier un classements des principaux frameworks utilisés par les développeur. Baptisée « Users' Choice Survey on Frameworks » l'étude souligne que la facilité d'utilisation est visiblement un facteur prépondérant pour les programmeurs. Arrivé premier des réponses de plus de 400 développeurs, .NET de Microsoft devance le Google's App Engine et le Google Web Toolkit. A l'autre bout du classement, Rails serait très mal noté.

• Assembly as a First Programming Language?

  - by Anto

  How good of an idea do you think it would be to teach people Assembly (some variant) as a first programming language? It would take a lot more effort than learning for instance Java or Python, but one would have good understanding of the machine more or less from "programming day one" (compared to many higher level languages, at least). What do you think? Is it a realistic idea, at least to those who are ready to make the extra effort? Advantages and disadvantages? Note: I'm no teacher, just curious

• How do I set the root password so I can use su instead of sudo?

  - by Zignd

  Warning: Directly logging in as root is like playing with fire, because one little typo is enough to lose critical data or make your system unbootable. Note that desktop environments will also function incorrectly if you login to them as root. See these questions for the reasons behind why sudo is preferred and why root-login is disabled by default: What are the benefits of sudo over su? Why is there no option to login as root? Instead of letting you set a password for root during install Ubuntu set it to * for no password and disables the actual account login, however even with this being said you can still use root in ubuntu by sudo. So how to set a root password on Ubuntu?

• VirtualBox Port Forward

  - by john.graves(at)oracle.com

  A great new feature in VirtualBox 4.0 is the ability to use NAT networking and forward ports without needing to use ssh -L/-R tricks.  This is great for booting multiple VM domains simultaneously.  It is possible to have several instances which map back to the host machine and different ports on localhost:* automatically forward to the correct VM.  This avoids the hassle of setting up dns entries or static IP addresses.In this example, I'm mapping the host ports 3xxxx to the VM's well known server ports.Note: It is important to setup the Frontend HTTP host/port to avoid incorrect URL rewriting.You may also need to setup an http channel to deal with local traffic which uses the network address 10.0.2.15Happy VMing.

• How do I get to the maintenace shell?

  - by Narida

  I'm asking this because initially, my problem was this (power failure during installation, so I typed the following instructions in the maintenance shell: sudo mount -o remount,rw / sudo dpkg --configure a sudo mount -o remount,ro / sudo sync sudo reboot The first three lines worked, afterwards, my computer (a Dell Inspiron 530) got stalled for several hours, so I unplugged it. When I turned it on, the log in screen appeared, and after I try to write my password, it leads me back to the log screen. I must note that when I typed the first three lines during the maintenance shell mode, it said that the errors which were encountered during processing were: initscripts bluez gnome-bluetooth So, what do I have to do in order to get back to the maintenance shell so I can type code again? And, what code do I have to write in order to restore my computer? Thank you for your attention.

• Running projects from NTFS partition on Ubuntu

  - by the_hamster

  I'm dual booting Windows 7/Ubuntu 12.04. I want to run C++/Java projects from a NTFS partition, where I keep generally all my files and projects. I fiddled with the fstab. One time I removed 'noexec', the other I changed it to 'exec'. After that,each time, I remounted the partition and it still didn't work. I tried using sudo mount -o remount,exec /media/mypartition It didn't work either. There was a somewhat similar question already, but it didn't have the proper answer for me or I didn't know how to make it work(note: I am a total newbie with Ubuntu and Linux in general).

• To use Dart, the Java programmer has to work with 2 languages? [closed]

  - by Sridhar-Sarnobat

  When deciding on a technology to use for web apps, it's become a difficult choice between GWT and Dart and I am looking for guidance in deciding. GWT is a java programmer's dream because they don't have to learn a new language or have to worry about a separate IDE or extra plugin etc. GWT was sold using this value proposition - one didn't need to program in Javascript. But are Google making a U-turn and saying "go through the hassle of learning a new language" afterall? Or is it intended for there to be a Java to Dart compiler so that Java developers do not have to learn a new language? (this is not a rant, so I don't know why you are down-voting the question) Note: "the syntax is very similar" is not a justification. You could say why bother with GWT and just work with Java + Javascript directly.

• Problems with the colors on my screen. How can I check if it's a hardware problem?

  - by Ingo Gerth

  On my EEE PC netbook some colors are not displayed properly. Specifically, dark gradients such as in the window title do not look very smooth, but rather look like a sequence of a couple of different colors. This is especially visible when opening a menu, for example the "File" menu in Firefox. As you know this one is black, and it looks terrible on my screen. It is not just black, but the colors look really graded and far from a smooth gradient or anything. Now I am wondering: Is this a hardware or software issue? And how can I check this? If it should be a fixable problem I think it would be worth another question. Note that I am using Natty. If my problem description is not good enough I can try to take a photo.

• Moving OVD from Test to Production

  - by mark.wilcox

  Customer asked support "How to move a test OVD server to production". There is a couple of ways to do this. One way is to clone the environment: http://download.oracle.com/docs/cd/E15523_01/core.1111/e10105/testprod.htm#CH... Another way - which is particularly useful if you want to push configuration from a parent OVD server to children in a cluster: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10046/basic_server_set... Note if you use the second option and you have any data in a Local Store Adapter - you may also need to use the oidcmprec tool to synchronize that data: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10029/replic_mng_mon.h...

• Gnome question> Nautilus only starts as root user

  - by user7978

  Hello. I am running Ubuntu 10.04 62-bit. When I attempt to start Nautilus from the command line, it does not appear -- although a PID is generated. As root/sudo, I can start Nautilus fine. One note: I run e16 as the windows manager, so I do not use Nautilus to draw my desktop. However, even under this configuration, Nautilus used to run fine as a "regular" user. The permissions for Nautilus are the same as the other packages in /usr/bin. I believe this is a Gnome issue, but I'm fumbling at this point.

• Application to organize / manage installed networks

  - by vicmp3

  I was wondering if there is a Application where you can organize networks. I mean if you have installed some networks you have to note every pc's name, his ip-address and so on. Is there a Application where you can manage it? I saw the monitoring tools but that is not exactly what I'm looking for. Maybe I didnt explain me well, after all my englis his not so good :) For example if I install many different networks I write in a book how I configured them. I write pc-name ip-address ip-gateway ip-broadcast and so on for each network. It will be great if I can do it in a program to organize it well, and for example it gives me a node view of the network.

  So what I wanted to do. comperes(7zip) and split 600MB folder into 199MB parts but sadly when I tried to do this task with archive manager it gave me an error, but I know that if I use terminal it will work.

• What is an effective way to organize tasks for a new project?

  - by Dulan

  Is there a practical solution to organizing the initial tasks for a new project? To elaborate, imagine the features/stories/goals are laid out for a project. How might one go about organizing those into sane tasks for the first few versions? The scenario I typically have in mind has the features listed as a high-level reference for what the end user-experience should involve. The tasks for constructing such features are then broken down into chunks (such as "create interface for X component"). Such a task is not necessarily "tied" to only that feature and may be useful when building subsequent features. Is breaking features down into small, code-able solutions valid? Or should they be slightly removed from any specific implementation? I do not expect that there is one "right" answer to this question, but I am looking for a fairly pragmatic and unobtrusive approach. As a note, I'm looking for solutions that are independent of any tools or "systems" used for managing the tasks themselves.

• Nautilus menubar behind top panel ubuntu 11.10

  - by pst007x

  The nautilus menubar appears behind the top taskbar, I have tried to uninstall appmenu-gtk3 and restart nautilus as suggested but no joy. There is a duplicate but it is closed with no proper solution, disabling nautilus is not a solution! Thanks all Note: Not resolvable, it is a bug, wait for an official fix! A fresh install corrected the problem. The only work around is to disable Nautilus as your desktop manager. I suggest the easiest way is to use gnome-tweak-tool found in the repos. Thanks all
