  • Unable to login following permission changes in device manager (11.10 + Gnome)

    - by Symanuk
    (Running Gnome 3 on Ubuntu 11.10) Everything working well (at least a couple of months), until recently when I changed the permissions through the device manager on the sda1 /2/ 3 drives, thinking it would save all the switching I seem to have to do between users in order to see / use files I previously copied across from an external drive. Now when I boot up the Ubuntu splash screen loads indefinitely, and if I go in through the GRUB / recover option, i'm getting a load of negative permission messages back (regardless of using the fsck or remount options) Either way = unusable machine (Laptop Dell Inspiron n5050), and no way through to login. I'm looking for: (1) a way back in so any help greatfully received (answers need to be pretty basic as i'm a novice), and (2) if i'm to learn anything, a decent thread on setting permissions within Ubuntu / Gnome 3. I'm new to both Ubuntu & Linux, so please be gentle!! Cheers

  • After installing ubuntu 12.04 my internet connection has completely disappeared

    - by Tony
    On my PC after installing Ubuntu 12.04 my networks are completely gone. Inside the terminal, after typing in nm-tool I get the following: The program nm-tool is currently not installed. You can install by typing: sudo apt-get install network-manager After I type that in then my password I get this: Reading package lists... Done Building dependency tree Reading state information...

  • What significant progress have we made in Rapid Application Development?

    - by Frank Computer
    Since the introduction of OOPL's and event-driven programming, I feel like developing an application has become harder and more tedious, when it should have been the other way around! We should have development tools which can generate prototype apps which can be quickly and easily customized into sophisticated applications, even by novice users! We really need new ideas in this area of software development and I would like to know of any good ideas. If we can't really find them, then we should ask "Where did we miss the boat?.. Why?.. and What should we be doing?"

  • Is it safe to configure "Shutdown" on "When laptop lid is closed" ?

    - by Takkat
    To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?

  • How much should I rely on Visual Studio's Auto Generated Code?

    - by Ant
    So I'm reading up on ASP.NET with VB.NET and I want to start making my own, professionally built website using ASP. I'm wondering though; I'm still using the basics so I'm really just a novice, but how much should I rely on Visual Studio to create my elements? Should I make my own text boxes and have my own login routine, or should I just use ASP's login features? I know eventually you have to use your own classes and such which is where the real coding comes in, but I'm not sure how relaible, flexible and secure the pre-wrote elements are? Any help would be greatly appreciated.

  • Update installed on netbook.. now sidebar icons have disappeared! :oS

    - by Lolly Collier
    hope someone can help. I am not extremely computer literate and my brother installed Ubuntu on my Acer net book when my windows crashed irretrievably . I recently (day before yesterday) had a box come up saying an update (i think it was 10 or 11 .something) i followed the instructions to download and install it and now, all my side bar icons have disappeared. I happened upon an Internet connection by chance and have no idea whatsoever how to get them back. This is quite probably a really stupid question and a really easy fix but as i said earlier, i am pretty much a novice, very far from a computer expert! Thanx in advance :o)

  • How are Programming Languages Designed?

    - by RectangleTangle
    After doing a bit of programming, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves are written. I mean this in both senses. Such as how it was literally written (ie, what language the language was written in). As well as various features like white spacing (Python) or object orientation (C++ and Python). Where would one start learning how to write a language? What are some of the fundamentals of language design, things that would make it a "complete" language?

  • GRUB install error

    - by Rohit
    Whenever I try to install Ubuntu, I get a fatal error that reads: 'Executing'grub-install /dev/sda' failed. This is a fatal error.' Its the same as this, but my graphics appear to be running fine. Also, I'm a complete novice at this and really need simple instructions to understand what I'm doing. I've tried booting from a LiveCD and a USB stick. I don't want to dual boot it because its an old computer that I erased XP and plan on only using Linux on it. When I used a USB stick and set the persistent file storage high, I was able to run it, but only as long as the flash drive was plugged in.

  • I'm a beginner Java programmer but I want to be useful

    - by user105418
    Programming has always interested me, but after learning some of the basics of Java(I'm talking high school level), I don't really know what to do from there. I want to be able to apply what I learned in some way, whether it be a volunteer project or something, but I probably don't know enough programming. Is it possible for a novice Java programmer to be useful in some way whatsoever. I want to do this because I feel like I could learn more about programming by helping people in theirs, but I'm not sure if I'm even able to this though. Does anyone have any suggestions on how I can contribute to other people's project in some way or how to apply it in some way?

  • mouse and mousepad not working properly

    - by snake
    Ubuntu 12.04 LTS Samsung Q35 The mouse pad has stopped working, only the buttons work. The external mouse is also behaving very oddly, the mouse pointer works, but the button is not working properly, it has to be pressed many times or held down to select anything, and when anything that I select behaves as though the mouse is being clicked all the screen, settings will keep changing, the page will scroll, sliders will move up and down, tabs will toggle etc, so everything is unusable with the mouse, cannot even use the browser as it keeps scrolling the page up and down. I have tested the mouse on another computer, and it works fine. Please bear in mind that I am also a complete Linux novice, I installed Ubuntu on an old laptop for my kids, that is the limit of my experience.

  • No internet - please help?

    - by All
    I just got Ubuntu and I am really really really a linux novice. I can't get the wireless to work? I played around with it until I saw it says "wireless firmware missing" - Hardware address 00:14:A5:6A:17:C2. On my laptop there is a button that looks like a little antenae that means the wireless is on. The funny thing is that this button does not seem to do anything right now - the light is not lit up and does not light up. Any thoughts you have on getting this going are appreciated!

  • Where can I hire a trustworthy professional PHP programmer?

    - by JJ22
    I wrote a php application for my website that really needs to work well and be as secure as possible. I'm a novice php programmer, so while my application seems to work well, there may be inefficiencies or security vulnerabilities. I feel that I should have someone look over my code before making the application publicly available, but I'm hesitant to just post it online because it handles some rather sensitive things. Where can I find a competent, trustworthy, and relatively inexpensive php programmer who would be willing to review a few thousand lies of well-commented easy-to-read php code? Thank you!

  • Can I properly use NS2 on latest Ubuntu 12.04?

    - by Nwe Nwe
    I am a novice user for Ubuntu because I need to work with NS2. NS2 properly work only in Linux, Ubuntu. Now, I wonder if it can properly work on latest version Ubuntu. My current window is Window7. I also want to use Window7. So, which one will be better on parallel booting of Window 7 and Ubuntu or using VMWare on Window7 to install Ubuntu. My RAM is 4G. My processor speed is 1.6G. If I use VMWare, my C drive is only extra 10G. So, does VMWare can work properly in D drive? Please let me know which way is the best for my situation. I hope the advice from anyone. Thanks in advance.

  • Are my Google Analytics ( 2 domains 1 site) duplicated or unique?

    - by MarcDJay
    We have recently built a new website with a new domain to replace an old website, and on the advice of our IT guys and web dev team have pointed both oldaddress.com's & newaddress.com's a records to the new website. Now, they both share the same google analytics code (UA-12345-1) and as such we have two entries in the Google Analytics dashboard. The problem is I'm still fairly novice with GA and as the reports seem VERY similar (~25k pageviews for each domain), are these figures exclusively for that domain? For example: oldaddress.com 25,400 pageviews newaddress.com 25,600 pageviews Does this mean that in total for this website I have 51,000 pageviews. Hope this is clear enough but let me know if anything needs clarifying. Thanks.

  • apache2 doesn't start with location

    - by Geod24
    I have a small domain, which I use only for personal purposes. I'm the main user, and have at most 3-4 users at the same time. I use apache2 with passenger to serve redmine. So I start with an empty apache2: root@xxxxx:/home/# service apache2 start [ ok ] Starting web server: apache2. root@xxxxx:/home/# a2dissite Your choices are: Which site(s) do you want to disable (wildcards ok)? Then enable my site, and restart (not reload) apache2: root@xxxxx:/home/# a2ensite 200-redmine Enabling site 200-redmine. To activate the new configuration, you need to run: service apache2 reload root@xxxxx:/home/# service apache2 restart [FAIL] Restarting web server: apache2 failed! [warn] The apache2 instance did not start within 20 seconds. Please read the log files to discover problems ... (warning). root@xxxxx:/home/# service apache2 restart [FAIL] Restarting web server: apache2 failed! [warn] There are processes named 'apache2' running which do not match your pid file which are left untouched in the name of safety, Please review the situation by hand. ... (warning). root@xxxxx:/home/# pidof apache2 20948 Here's my 200-redmine.conf: PerlLoadModule Apache::Redmine <VirtualHost *:80> ServerName redmine.xxxxx.xxx DocumentRoot /var/www/redmine/public/ ErrorLog ${APACHE_LOG_DIR}/redmine.error.log CustomLog ${APACHE_LOG_DIR}/redmine.access.log common MaxRequestLen 20971520 <Directory "/var/www/redmine/public/"> Options Indexes ExecCGI FollowSymLinks Order allow,deny Allow from all AllowOverride all </Directory> SetEnv GIT_PROJECT_ROOT /opt/git/ SetEnv GIT_HTTP_EXPORT_ALL ScriptAlias /git/ /usr/lib/git-core/git-http-backend/ <Location /git> PerlAuthenHandler Apache::Authn::Redmine::authen_handler PerlAccessHandler Apache::Authn::Redmine::access_handler AuthType Basic Require valid-user AuthName "Redmine Git Repository" RedmineDSN "DBI:mysql:database=redmine;host=localhost:3306" RedmineDbUser "redmine" RedmineDbPass "password" RedmineCacheCredsMax 50 </Location> </VirtualHost> Now if I comment out the ScriptAlias / stuff, it works !

  • What are modern and old compilers written in?

    - by ulum
    As a compiler, other than an interpreter, only needs to translate the input and not run it the performance of itself should be not that problematic as with an interpreter. Therefore, you wouldn't write an interpreter in, let's say Ruby or PHP because it would be far too slow. However, what about compilers? If you would write a compiler in a scripting language maybe even featuring rapid development you could possibly cut the source code and initial development time by halv, at least I think so. To be sure: With scripting language I mean interpreted languages having typical features that make programming faster, easier and more enjoyable for the programmer, usually at least. Examples: PHP, Ruby, Python, maybe JavaScript though that may be an odd choice for a compiler What are compilers normally written in? As I suppose you will respond with something low-level like C, C++ or even Assembler, why? Are there compilers written in scripting languages? What are the (dis)advantages of using low or high level programming languages for compiler writing?

  • What web-development platform should I use considering Time-To-Market?

    - by Jonas
    I have been looking at a few differend platforms for my coming web-development project. I would like to hear what web-development platform is recommended when considering Time-To-Maket. Suppose that I already know the programming language well, but not the web-framework. The OS will be Linux. My requirements and priorities: Time-To-Market RESTful Maintainable code Scales-up (not dog-slow) The one I have looked at but never used are: Java and Play! Framework or GWT Python and Django PHP and Zend Framework Ruby and Ruby on Rails Erlang and Nitrogen and Webmachine Scala and Lift C++ and Wt C# and ASP.NET Mono It's a bonus if the framework has support for making sites for mobile phones.
