• Installing Ubuntu 13.10 'Saucy Salamander' on L75D-A7280 hangs on a black screen

  - by Riven

  Trying to get Ubuntu 13.10 to work and it will not. Seen that somebody is having a similar problem, some things failing then it just hangs on a black screen (after pressing F1 to see what it's doing). My system is a Toshiba Satellite L75D-A7280, and I have tried two different files that I had downloaded from Ubuntu.com with no luck. My laptop came with Windows 8 and following the dual-boot directions Ubuntu 12.04 was installed and worked perfect, except for completely obliterating Windows 8 and voiding my warranty, meaning neither Toshiba nor the retail center I bought my system from can help me legally, besides giving advice... nor can I return it to get a non-UEFI based system. I really need to figure this out, I am a student and need my laptop working properly with any OS I put on it. Will continue searching for any information I can find.

• Video playback not working in Ubuntu 11.10

  - by Dave M G

  (Ubuntu 11.10, Gnome Classic with Compiz, Nvidia graphics card) This problem occurs with every and all video, whether it's a Youtube video in Firefox, an AVI file in movie player, or any other video. Video simply does not work. When I start any kind of video, the image halts after a second or two. The sound, however, continues. Before it seemed that if I delete all the files in ~/.gstreamer-0.10/, then reboot, the video will play. However this is no longer the case. Manipulating files in that directory does nothing to help the situation. I am now no longer sure this is a gstreamer issue or something else. I am open to any and all possibilities. How can I get video playback to run smoothly on my machine?

• Installing SQL Server 2012 on Windows 2012 Server

This is by no means exhaustive. My goal in writing this is to help you get a default instance of SQL Server 2012 up and running. I do not cover setting up the Hyper-V virtual machine.

• Final steps in installing Matlab2012 on Ubuntu 12.04

  - by Mattia

  I have a problem with the MATLAB 2012 installation. After having installed it using alt+f2 and having used gksudo nautilus I have installed MATLAB in the correct folder which is: /usr/local/MATLAB/R2012a Then I inserted the license and the window told "activation complete" or something like that. This made me happy, but only for a while because as soon as I try to search for Matlab within the applications I cannot find it and neither if I try to run matlab into terminal it says: command not found Can someone help me!? Tanks in advance!

• GPG Workflow in 11.04

  - by Ross Bearman

  At work we handle the transfer of small bits of sensitive data with GPG, usually posted on a secure internal website. Until Firefox 4 was released, we used FireGPG for inline decryption; however the IPC libraries that it relied upon were no longer present in FF4, making it unusable and it will no longer install in FF5. Currently I'm manually pasting the GPG blocks into a text file, then using the Nautilus context-menu plugin or the command line to decrypt the contents of the file. When we're handling large amount of these small files throughout the day this starts to become a real chore. I've looked around but can't seem to find much information on useful GPG clients in Ubuntu. A client that allowed me to paste in a GPG block and instantly decrypt it, and also paste in plaintext and easily encrypt it for multiple recipients would be ideal. So my question is does this exist? I can't seem to find anything about this with obvious searches on Google, so hopefully someone here can help, or offer an alternative workflow.

• Sudden crash with gnome and unity

  - by cent89

  I've a Toshiba Satellite Pro U400 with Ubuntu 11.10. Very often when I'm working on the pc reboots itself, or close all programs and return to the login screen. This is very annoying, often I lose my job I'm doing, sometimes I make bad figures while projecting slides or movies in public. What happens is that with Unity 3 with Gnome, so I do not depend on these. I also checked the log files but with little success because I can not interpret them the best. Can you help me solve this serious problem? thanks. Roberto

• How to Get Vim to do Filename Completion Even When You are Root

  - by user12608033

  From the Obscure Unix Admin Tip of the Day section... If you occasionally edit files as root (I never do, I always use pfexec, wink wink), then you may have noticed that the vim (Vi Improved) editor that normally does filename completion via the <Tab> key now gives you something like: :e /etc/mo^I when you try to open up /etc/motd with a little less typing So, there are at least three solutions to this: Use <Ctrl>-E instead of <Tab> Use the "-N" flag when you start Vim :set wildchar=<Tab> (Enter those 5 characters, not an actual Tab) The reason for this? It seems that when you are root, Vim sets it's "compatible" flag, which makes it behave more like its ancestor vi. In turn this makes Vim set 'wildchar' to <Ctrl>-E. For more info, read the section you get when you enter :help cmdline-completion

• Facebook likes reset after moving to HTTPS (URL manually set in script, though)

  - by aarondicks

  Hi fellow Facebook developers. I've got a question regarding the Facebook like button. We worked on a piece recently that embeds a number of social share buttons (please see the source code below or here on Harvey Water Softeners' website) When the piece was released, it was on HTTP, and received over 2k likes (the URL 'slug' hasn't changed at all). The site was recently migrated to permanent-on HTTPS, and the like data has been reset, and we've been left with 50 new, recent likes. If you see in the source code, the URL is set explicitly to like the HTTP version, which I believe to be correct. Can anyone help me work out what's happened here? Here's the HTML bit of the like button: <div class="fb-like" data-href="http://www.harveywatersofteners.co.uk/history-interior-design" data-layout="box_count" data-action="like" data-show-faces="false" data-share="false"></div> Thanks in advance Aaron

• java developer who wants to raise skill level for better career growth [closed]

  - by Rahul Shivsharan

  I have an experience in Java language and in JEE related Framework for about 5 years. In these 5 years i have worked on Core java, Spring, Hibernate, JPA, Struts 1. Now just to be prepared for the near future, i am thinking to learn some new programming language or some new technology, this will help me out to be a more elligible employee. So my question to you is, which new technology or language should i learn, my target is for next 3 years. So just in case if Java fades out (thought it won't) than i can jump on to this newly learned stuff. Where should i start from ? Should i learn some other language in JVM like Scala, Clojure, Groovy, JRuby ? Or should i learn some altogether different language like Python or Erlang, Perl ? Or new technology which is related to NoSQL, like MongoDB, Hadoop, CouchDB. Or learn few current happening things in market like RoR, Node.js, LessCss or Sass, Coffee Script ? Can anybody give me some hint,

• Where do the responsibilities of build tools end and those of CI tools start?

  - by BrandonV

  In the delivery of software, and within the sense of the deployment pipeline, where do the responsibilities of build tools, like Maven, end, and the responsibilities of CI start? As a rough example of a problem that arises; should build tools have any responsibility to the configuration and execution of acceptance tests when they are further down the pipeline than actually building the artifact? I'd like an answer that addresses in the sense of deployment lifecycle phases rather than in specifics, like my example. Although examples would help bolster the answer.

• Alot of Pirated Material on Someone's Website - What Can Be Done?

  - by The Russian Shop

  Hi, We've developed our website for over 10 years. Recently a website in China has begun to pirate our images and product descriptions (they are showing "new" March offerings). Nearly all of the items they "offer" are ours. Their whois leads to an outfit in France which by chance also hosts a website for Steroids, and both the Steroid and the pirate site share an 800 phone number (coincidence??). The pirate site lists "their" products as being available in mass quantities, though very often the actual product is one-of-a-kind. The images they've stolen appear in google searches alongside our own!! Clicking on any product at the pirate site leads to nowhere. Calls to the 800 number lead to a recorded answer. No reply to our emails (funny if they would have!) Any suggestions on what to do? Much obliged for any help. https://www.collectiblereview.com (the pirates) http://www.anabolic-store.com (steroids)

• Ubuntu not booting properly

  - by user86998

  I just bought an Asus EeePC with Ubuntu 12.04 installed on it. After turning it on and performing the updates it didn't boot properly and showed a screen saying it was working on low graphics mode, but I wasn't able to get to the GUI. After some searching, I tried renaming xorg.conf.failsafe to xorg.conf using the mv command. After rebooting I got to the Ubuntu GUI but it was stuck to a 800x600 resolution, track pad not working and not detecting my Wi-Fi. After rebooting again it goes straight to console tty1. I'm completely new to Ubuntu and Linux. If some one can give help? I think the best would probably be to reinstall it from scratch, but I don't know how.

• Maya and Game Engines (i.e. Environment Testing)

  - by DiscreteGenius

  What does it mean if I'm designing an environment and I want to test it in the game engine, to see what its like to "run" [or fly] around my environment? I heard an instructor say that exact thing in a Maya training video and I'd like to know more about "How Game Engines and Maya are related to each other." He stated this would be done to see how things look in "size" (e.g. I assume he meant: 'How big is the cathedral, bridge, wall, building, etc.'). I've tried to research such information but it's too complicated, and detailed. I just want a simplistic response to my query. Thanks to everyone willing to help and not criticize my question.

• "BAD idea" warning when trying to recover Grub, after Windows removed it

  - by Shazzner

  Tried sudo grub-install on sda1 but it complained about being a BAD IDEA. I had to install windows for a work related issue so I used a separate disk (I had used it for ubuntu on this computer, but bought a bigger disk so installed ubuntu on that and left the old one in in case I needed an old file). Windows installed fine but overwrote Grub. So if I choose the Ubuntu disk to boot first in BIOS I get a blank screen. I googled and followed this advice: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows However, when I get down to this section: sudo grub-install --root-directory=/media/0d104aff-ec8c-44c8-b811-92b993823444 /dev/sda1 I get this: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea… --recheck does nothing. Any ideas?

• 12.04 x64 Server Login Failure

  - by ThoughtCoder

  After some serious GRUB issues after routine kernel updates, forcing a grub-reinstall via chroot and some single-user mode maintenance, I now cannot login to my server (except via single-user mode) When attempting to SSH to the server my connection is reset immediately after entering username - no password prompt is presented. I've plugged in my monitor and keyboard to the headless server and when trying to login I receive: login: "PAM Failure, aborting: Critical error - immediate abort" immediately after entering my username - again, no password prompt is displayed. I am able to gain access via kernel recovery mode and login as root through single-user mode with networking. I've attempted a dpkg reconfigure believing I may have had some incomplete/borked packages, but to no avail. Looking through /etc/pam.d/login doesn't seem to lead me in any obvious directions and I'm afraid I'm out of ideas. Googling doesn't help me much, one guy reinstalled (really don't want to do this) and the rest I could find were old Gentoo related bugs. Any tips?

• How can I set up private, per-user sections on Joomla?

  - by Michael Paulukonis

  For this weekend's GiveCamp project, my team has been tasked with adding some functionality to an existing Joomla-powered website for a non-profit. A certain type of user will login, and have access to a personal area where they can upload files, check for messages, see tasks that have been assigned, etc. Each user would have their own area. They would not be creating pages, and their information would only be visible to themselves (or a site-administrator, of course. No sort of weird HIPAA privacy involved). None of us have worked with Joomla before, but we'd like to help this non-profit. We're not sure if we're searching using the wrong terms, or if we're just not finding it. Is such a solution possible in Joomla? And/or are we better off building some standalone solution that interfaces with the same mySQL database as Joomla?

• i accidentally disabled my ubuntu profile

  - by Mack

  I was trying to upgrade my 2nd computer's hard drive, and in the process, I un-admin'd and disabled my account. I'm using the guest account right now. I've tried everything that ask ubuntu has to offer (or at least after 5 hours of searching, trying, and failing) i.e., creating a new account (didn't allow me to do it), usermod, passwd, anything involving sudo, hell, I can't even get into recovery mode with the left shift thing... I really want to get into my account. Please help me.

• Cannot resume from hibernate (s2disk)

  - by hwjp

  I seem to be able to hibernate OK using s2disk, but when I switch the laptop back on, it seems to hang half-way through the "resuming" menu. The splash screen looks healthy, it seems to be trying to resume from the correct disk, but it hangs about half-way through, with three little pips. One great help would be - where can I find the logs, and how do I get more verbose ones? There is some info in /var/log/pm-suspend.log, but that all seems fine, just lots of hibernate: success messages... How do I switch on more verbose logging in s2disk? And what about the resume process, where are the logs for that, and how can I make them more detailed? Background: the standard Ubuntu hibernate wouldn't work, so I've install uswusp and its associated tools - s2disk etc. That initially made things worse, but a fair amount of fiddling with its config, my swap size and so on seem to have got it at least seemingly successfully suspending...

• The #OOW Party May Over...

  - by user462779

  ...but there's no reason why we can't look forward to the next one! It's going to take all week for me to catch up on last week's neglected email, sort through the freshly-collected business cards, and generally make sense of the mad dash that is Oracle OpenWorld. So I've been playing this amazing video (produced by Lozano Productions) to remind me of the last business/IT conference marathon I survived: Collaborate 2012. It was an amazing event where we officially launched the new design of Profit and enjoyed a drink with some of our closest friends--Oracle partners, customers, and peers. Many thanks to those who came out to celebrate and who continue to help make Profit a success. It was a great time that resulted in a lot of great new work and new relationships. So I'm taking a time out to remember that the hard work is worth it. See you in Denver next year!
