• 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?

• How do I run Microsoft Explorer 8 plus on Ubuntu?

  - by user169487

  First off, you should know I'm a Ubuntu newbie who has become passionate since my strangely low-priced Dell computer showed up with Ubuntu loaded on it and it could do almost everything I need from a computer. But now I've got a problem. I know, it's like asking how to use a cassette player on your computer, but in South Korea EVERY website is made to work with exclusively on MS Explorer PLUS Active X, which Microsoft finally killed with 9. Hence, I have to use 8, as there are some Korean sites I need to access for searching, banking, etc. So I see that the way to go is to load PlayOnLinux, but then I it tells me to delete these. Do I really have to do that? Should I just hit "Install Anyway"? Or would that be just asking for trouble?

• 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

• 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?

• Don’t Like New Google Search Interface? Switch To Old Interface

  - by Gopinath

  Google recently adopted a new user interface layout for it’s search engine. The new layout is very different to classic one, it provides many options on the left side to choose for enhanced search operations. Even though many users like this new interface, there are few who are more comfortable with the classic interface. If you are one among those who wanted to switch back to classic interface, you can access it by using the following http://www.google.com/webhp?hl=all Join us on Facebook to read all our stories right inside your Facebook news feed.

• My Herokuapp is inaccessible from custom domain name

  - by picardo

  I have a Heroku app that is located at myapp.herokuapp.com. I have mapped a domain name to this app, using the A properties. I followed the instructions on Heroku's website to the letter, and it worked for a few days. Now when I try to access the site from the custom domain, it's timing out! On Chrome, I am getting "Oops! Google Chrome could not find that page!" message. I tried pinging the name as well, but I got this error: ping: cannot resolve yourhostname.org: Unknown host The app itself is working and I don't see any error messages from Heroku. Or from new Relic. What's going on here? Also tried running host and this was the error message: ;; connection timed out; no servers could be reached

• Ubuntu 12.10 and Gnome-Shell : can't see nor launch apps except with Alt + F2

  - by Ratoune2008

  I've installed Ubuntu 12.10 and Gnome-Shell 3.6. Everything worked fine till the moment I've began to customize the main menu (apps wich appears in Dash and so on). I don't know wether I've done something wrong or if there is a bug : suddenly, the Dash became empty. My favourite docks too, except the "Show apps" button. When I activate it, there is only an empty dash, no apps showed. The only way I can access an app is using the "Alt+F2" shortcut. I've tried to restart gnome-shell (Alt-F2 / r) but nothing has changed... A logout and a reboot have not changed ... Do you know how to repair the gnome-shell ? Thanks for your help...

• USB internet not accessible

  - by Eric

  I'm brand new to ubuntu and linux. We access internet from a usb stick issued by a local telephone company. When I plug the stick into the computer, I see the device listed under internet connections as a mobile broadband device but it is grayed out and inaccessible. I tried to create a new mobile broadband connection but my country (Gabon) is not listed and we have no payment plans per se (we pay from a pre-paid card system).. Any clues as to how I can get the system to recognize the internet connection? Thanks for any help...

The final section deals with advanced topics including a thoroughly practical intruction to windows services. There are copious coding examples and useful tips. Many chapters begin with a quick problem solver solution reference. In short "Introducing Visual C# 2010" in the words of the sub title, is an excellent start to your C# journey with an expert by your side leading by example.

• How to enable a symlink in this case

  - by Bragboy

  I cannot categorize this question under ubuntu since it has nothing to do with it. But I know people here can definitely answer this. I login to one of my deployment boxes using SSH (no ubuntu here). I am working in a tool called TeamCity which uses a folder called ".BuildServer" under home directory of the user. This folder may grow in size as the application runs but the current user is only given a limited amount of space. But the good thing this I got a folder access outside /home/deploy (deploy being the user here) folder. I now want to link this .BuildServer inside the /home/deploy directory to the other folder where I got permission for (meaning all the files should be re-routed to that directory) Hope my question was clear, please help.

• Ubuntu 12.04 External HD Issues

  - by Anthie Georgiadi

  I am experiencing one more problem with my Ubuntu 12.04... I have an External HD (500GB) which is NTFS formatted. I connected this HD on my Ubuntu 12.04 and copied some files. When I connected the HD on a Windows 7 machine I could find the folders (the were visible) but I wasn't able to copy/cut/delete them. However when I opened the folders I could handle the material (mp3s) in them. Does anybody know how can I fix this? How can I fully access and modify folders copied from Ubuntu via a Windows machine? Thanks in advance!

• What is Google's repository like?

  - by Ricket

  I heard Google has a giant private (internal) repository of all of their code and their employees have access to it so that when they are developing things they don't have to reinvent the wheel. I'd like to know more about it! Is there anyone here from Google that can describe it in a bit more detail, or do you know a bit more about it? I'm interested in knowing mainly about how it's organized and how they can make it easy for an employee to find something in such a giant codebase as it must be.

• Issue with wired network

  - by Shiju Nambiar

  I have ubuntu 12.10 (downgraded from 13.04 when I faced this issue). I am a newbee and don't know much of technical side like commandline on the terminal. I have a wired internet connection and it was working just fine for last few months since I installed ubuntu. my OS got upgraded to 13.04 and it was still fine. Since last 3 days, network shows connected, connection stays for few seconds and then websites stop loading. Connection shows as connected, but pages don't load. I have to reconnect again to access a website and the connection goes off again in say about 10 to 15 seconds. So I use my internet by connecting and disconnecting every few seconds.

• Segment subdomains with Google Analytics?

  - by andrewpthorp

  So, when a website has multiple subdomains: www.example.com foo.example.com bar.example.com What is the best way to use Google Analytics to segment the data? I would prefer have access to 'All Data', 'Data from foo.example.com', and 'Data from bar.example.com'. I tried setting up 3 different views, and setting a filter on the foo/bar views that says: Include only traffic from the ISP domain that are equal to foo.example.com. However, I am not seeing any data collected into that View. I do, however, see all data in the 'All Data' view, but I can't figure out how to segment the data. I am including the analytics.js in the application.haml layout, which is always loaded in this app. Thanks!

• Law of Demeter in MVC regarding Controller-View communication

  - by Antonio MG

  The scenario: Having a Controller that controls a view composed of complex subviews. Each one of those subviews is a separated class in a separate file. For example, one of those subviews is called ButtonsView, and has a bunch of buttons. The Controller has to access those buttons. Would accessing those buttons like this: controllerMainView.buttonsView.firstButton.state(); be a violation of the LOD? On one hand, it could be yes because the controller is accessing the inner hierarchy of the view. On the other, a Controller should be aware of what happens inside the view and how is composed. Any thoughts?

• Many ui panels needs interaction with same object

  - by user877329

  I am developing a tool for simulating systems like the Gray-Scott model (That is systems where spatial distribution depends on time). The actual model is loaded from a DLL or shared object and the simulation is performed by a Simulation object. There are at least two situations when the simulation needs to be destroyed: The user loads a new model The user changes the size of the domain To make sure nothing goes wrong, the current Model, Simulation, and rendering Thread are all managed by an ApplicationState object. But the two cases above are initiated from two different UI objects. Is it then ok to distribute a reference to the ApplicationState object to all panels that need to access at least one method on the ApplicationState object? Another solution would be to use aggregation so that the panel from which the user chooses model knows the simulation parameter panel. Also, the ApplicationState class seems somewhat clumsy, so I would like to have something else

• VB6 general search form

  - by SilentRage47

  I'm working on an old vb6/access2003 app which is used to handle orders, bills of materials and that sort of things. I'm thinking about creating a form that I call every time the users needs to search for something. This should work like these: Click on the field to complete, let's say name of a buyer Open new form, search for the client and click on it Return the name of the buyer to the previous form (probably the header of the order) So, I would need to pass to the new form something that identify the type of search I have to do (so what access table to open) and return some values. Is my idea correct or there something better? I would like to use only one form for all the searches, now the app works with a lot of msflexgrid for every form.

• How do you hibernate/suspend Ubuntu like Windows or both at the same time?

  - by All Star Geek

  I'm using an ASUS laptop with Windows 7, and I just installed Ubuntu alongside Windows yesterday, using the no-risk option. I noticed, though, that I can't hibernate Ubuntu the way I did with Windows to save time, and, every time I use Ubuntu, I have to shut down to go into Windows, which has a slow boot. Is there any way that I could have Windows and Ubuntu hibernated at the same time so I can access both easily (preferably without having to hit a function key within seconds). When I try to hibernate or suspend Ubuntu with Windows shut down, the screen just turns blue and doesn't shut the computer off like a Windows hibernate or sleep.
