• Regain Sudo rights after removing from admin group

  - by berkes

  Hello, I accidentally removed myself from the admin group when editing the user. Now I can no longer use sudo. The error says: ber is not in the sudoers file. This incident will be reported. I booted up in rescue mode, but, when going into root prompt, it asks me for the root password. I don't have one, and providing with my own (first and only ubuntu-user) password, it won't allow entrance. My harddisk is encrypted, but only the /home/user part, not the entire disk, afaik. What can I do?

• Ubuntu partitions on Dell XPS13

  - by Francois

  I bought a Dell XPS13 with ubuntu 12.04 pre-installed. I want to reformat and repartition the machine but as I'm far from being a linux guru, I'm afraid to erase something important that could have been preinstalled by Dell. On the disk, there are 3 partitions: /dev/sda1 - Ext4 Linux bootable 248GB - witch is the system+user partition I guess, /dev/sda2 - Extended (?) of 8GB - What is this partion about? /dev/sda5 - Linux Swap of 8GB - whitch is for RAM and need to be reconduct (why only 1xRAM and not 2?) Do I have to care about /dev/sda2 ? According to you can I reformat to create a partition for /home whitout losing anything important (except user data of course) ? Thank you for your help

• How can I get Ubuntu 12.04 to boot on a Gigabyte 990Fx MB (efi problem?)

  - by Jeffrey

  I am trying to install Ubuntu 12.04 on a home made system with a gigabyte 990Fxa MB. I can make it through the install process. It does not boot. Windows 7 does boot on the same machine. Suse 11.4 boots on the same machine. Suse 12.4 does not boot. I think there may be an issue with the EFI / GPT system. I know very little about these systems. I really expected the machine to boot. What can I do to get the system to boot? Please direct me to a path to trouble shoot this problem. thanks Jeffrey

• Finally found a replacement for my.live.com&hellip;

  - by eddraper

  As I had alluded to before, the transition of http://my.live.com/ to http://my.msn.com/ caused me serious grief. I've been an RSS addict for many, many years and I found the my.live.com UI to be the ultimate RSS reader and gateway to the web. It had been my home page for a long time.  My.msn has a LONG way to go before it matches the elegance and performance of my.live. The site I ended up going with is http://www.netvibes.com/ .   It’s the closest thing I could find that could do four column tiles with a reasonable amount of information density .  I’d still prefer a lot less “chrome” and better use of space, but it’s as close as I’m going to get… One feature I really do like about netvibes, is the pagination feature.  The built in feed reader is also quite nice… All-in-all, I’d recommend netvibes…

• Avoiding duplicate bug reports

  - by Jaakko Seppälä

  I use Linux and other open source software in my home. As I'm not a professional coder, I usually report bugs to developers as my skills are not enough to solve problems on my own. What kind of things you want me to check before I send a bug report? I mean, once I thought I found a bug in Gedit and I couldn't find similar bug in Bugzilla. But after I sent the report, some developer said that the bug is already in Bugzilla as the bug was in GTK+, not in Gedit. Sometimes it might be hard for an amateur to guess whether some previously known bug would solve the issue I found.

• Lost the Hard Drive Icon from the Launcher

  - by Elbe

  I unlocked the C Drive icon connected to the Launcher. Once I moved it onto the desktop, it disappeared. In attempting to create an new icon, I was asked to create a mount point. The mount point directory then showed 2 links rather than the normal 1. I trolled the web for solutions, but I did not find one that addressed any of the stated issues. I attempted to find a solution to reconstruct the hard drives that were found during the install and listed in the Launcher but was unsuccessful in doing so. In summary, I would like to restore the /media directory to the original install which listed the drives correctly and have the drive icons appear in the Launcher as they did at the time of the installation of Ubuntu. I found where all the other icons in the Launcher located in the home Desktop directory but could not find anything that listed the hard drives or the floppy. Ubuntu 12.10 is installed and all the latest updates have been applied.

• How Fiber Optic Cables Are Made and Laid Across the Sea [Science]

  - by Jason Fitzpatrick

  We don’t know about you but yesterday’s video about how fiber optic cables work just made us more curious. Check out how the cables are made and laid across the sea. In the above video we see how fiber optic strands are manufactured, including how the draw tower mentioned in yesterday’s video works. Once the strands are manufactured, where do they go and how are they used? In the video below we see Alcatel-Lucent’s Ile de Sein, one of the largest and most powerful cable laying ships in the world. Check out the video to see cable storage wells that look like small stadiums. Finding out how the cables are made and what kind of planning and machinery it takes to lay them across the ocean is just as interesting as how they work.

• Removing an element not currently in a list: ValueError?

  - by Izkata

  This is something that's bothered me for a while, and I can't figure out why anyone would ever want the language to act like this: In [1]: foo = [1, 2, 3] In [2]: foo.remove(2) ; foo # okay Out[2]: [1, 3] In [3]: foo.remove(4) ; foo # not okay? --------------------------------------------------------------------------- ValueError Traceback (most recent call last) /home/izkata/<ipython console> in <module>() ValueError: list.remove(x): x not in list If the value is already not in the list, then I'd expect a silent success. Goal already achieved. Is there any real reason this was done this way? It forces awkward code that should be much shorter: for item in items_to_remove: try: thingamabob.remove(item) except ValueError: pass Instead of simply: for item in items_to_remove: thingamabob.remove(item) As an aside, no, I can't just use set(thingamabob).difference(items_to_remove) because I do have to retain both order and duplicates.

• SOA Suite 11g: Unable to start domain (Error occurred during initialization of VM)

  - by Chris Tomkins

  If you have recently installed SOA Suite, created a domain and then tried to start it only to find it fails with the error: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. the solution is to edit the file <domain home>\bin\setSOADomainEnv.cmd/sh (depending on your platform) and modify the line: set DEFAULT_MEM_ARGS=-Xms512m -Xmx1024m to something like: set DEFAULT_MEM_ARGS=-Xms512m -Xmx768m Save the file and then try to start your domain again. Everything should now work at least it does on the Dell Latitude 630 laptop with 4Gb RAM that I have. Technorati Tags: soa suite,11g,java,troubleshooting,problems,domain

• How to partition my hard drive for Ubuntu use?

  - by Damir

  Till now I was windows user. From now on I want to use only Linux. I have 500Gb HDD. How do I partition it properly? I read that there is no right or wrong way, but still, I am confused. I did something and I have primary partition mounted on / (160Gb) which I believe is a OS and 350Gb extended partition of which I have 4Gb of swap and 346Gb mounted on /home. I got used to C:\ and D:\ partitioning, but I don't see file system in that way. I am lost. Where is what? How can I make C:\ partition for OS and D:\ for apps, movies, music, photos. Or what I want is Windows way and I have to get used to Linux way?

• Ubuntu won't boot and it is stuck on the loading screen

  - by Jordan March

  I had just installed it as dual boot 2 days ago, and everything was fine. I was installing some programs (i think it was Play On Linux) and I don't think the install was 100% done when the battery died. Since then it won't boot into Ubuntu; it just stays at the loading screen. I did make separate partitions for boot root home and swap. Can anyone help me get it back and running again? Even if I have to reinstall it. I just don't want to go back through getting all those apps. I'm running Ubuntu 12.10 64bit on a Acer Aspire 5750 core i3 cpu 4gb ram

• Mount encrypted volumes from command line?

  - by cha

  If I have an encrypted external disk (or an internal disk that is not in fstab), I see an entry for it in Nautilus -- with an entry like "X GB Encrypted Volume". I can click on this volume, and am prompted for a password to decrypt and mount the device. But how do I do this from the command line? This wiki page, and other docs I can find, only refer to GUI methods of decrypting the device; but this won't do in the context of headless servers or SSH logins. Is there a simple way to get devices to mount to automatic locations in "/media" just like they would with the GUI? (I'm not asking about encrypted home directories -- I'm aware of ecryptfs-mount-private. This question is about additional encrypted volumes.)

• Is it possible to sync two computers without storing the files on a server?

  - by William

  I have a family member currently using Windows live mesh to sync a relatively large amount of files between computers. It is way over the Ubuntu One 5 GB limit and the Live Mesh 2 GB limit. However, Live Mesh gives him the options of syncing all the data he wants without storing it on Microsoft's servers. Does Ubuntu One have an equivalent option, performing just the sync computer-to-computer and not computer-to-server and server-to-computer? Do you have other recommendations? It does not necessarily have to be Ubuntu One, but I need it to be cross platform, working across Windows and Ubuntu. We also have computers outside of uour home network we need to sync to. This is one of the few things keeping him from switching to Ubuntu, and I'd be very grateful for any help.

• How should a new programmers behave at their first job? [on hold]

  - by Dimension

  What are programmers expected to know at their first job and how old will they typically be? I'm not going to school so I'm not around other programmers, therefore I have no idea what kind of programmers they are when they first get hired. I just want to get an idea what the median programmer's knowledge looks like. Will they already have had experience with version control? Are they writing good maintainable code? And what are they expected to do do? I'm programming my own software at home and because of the complexities of it and how new I am to programming I'm sometimes throwing all the code out and starting again with a better design. Aren't new programmers going to write terribly structured software for their employer, or is someone else going to be making the decisions on how everything is laid out?

• Locate a user's bashrc file

  - by Starkers

  Really confused. Upon running cat etc/passwd I have found this: postgres:x:117:126:PostgreSQL administrator,,,:/var/lib/postgresql:/bin/bash meaning I have a postgres user, right? I want to change the bashrc environment file of this user to make commands available to it. /var/lib/postgresql doesn't contain a bashrc file, and /bin/bash doesn't contain it either, so I don't really know what's going on. All I know is a created postgres using the useradd command, so why do I have some weird user with no home directory? So confused :(

• Is there an alternative to k3dsurf in 12.10?

  - by Sean Fitzpatrick

  I've just upgraded to Quantal Quetzal on my home computer and discovered that the program K3dSurf has been removed from the repositories. (Presumably since it doesn't seem to be in active development and still depends on qt3 libraries.) Does anyone know of a similar program (user-friendly and versatile) for drawing 3D surfaces? This has been a mission-critical program for me when teaching multivariable calculus, so I won't be able to upgrade at work unless I can find a replacement. (Yes, I could install directly from the program's website, but dealing with obsolete libraries sounds like a giant headache.)
