• Interviewing consultants

  - by SkyOrg

  I've interviewed a number of candidates for salaried positions. I was recently informed that we are hiring a consultant for a few months to help us develop a native iPhone application. We are a .NET shop and none of us have any experience with iPhone development. I've also heard rumors that we are planning to hire more consultants in the future to help develop on other various platforms. How should I interview these consultants, considering that I have no experience with this type of development? Without regards to platform specific questions, what are the things I need to keep in mind when interviewing consultants? Normally when I interview candidates, I'll ask questions that I know the answer to. I would never ask a candidate something that I don't know how to answer. Since this is a different situation, what do I need to ask in order to make sure they are subject matter experts in their respective fields? Is it appropriate to ask specific questions that we'll need to eventually solve during the interview?

If this is the wrong place to ask, can you tell me where I could ask this question?

• How to install Radeon 3670 HD graphics drivers for Ubuntu 10.04 64 bit with OpenGL 2.0 support?

  - by Daniel

  I've been having trouble with getting graphics drivers to work that support OpenGL 2.0. I've had some luck with the Ubuntu drivers, however these only support OpenGL 1.3. I thought I would document the methods that I have tried both to see if anyone else has ideas, and to save time for people with a similar problem. System details: Ubuntu 10.04 (Lucid) 64 bit Kernel Linux 2.6.32-44-generic GNOME 2.30.2 ATI Mobility Radeon HD 3670 Attempted Methods The methods I have tried are: 1. Installing Proprietary Drivers using the "Hardware Drivers" (Jockey) GUI This GUI offers an "ATI/AMD proprietary FGLRX graphics driver" however any attempts to install it result in a "Sorry, installation of this driver failed" error. The log file is here. There is an Ask Ubuntu question that covers this scenario, and notes that there is a known bug with Jockey. 2. Installing the Proprietary Drivers manually The answer to the question above linked to this wiki page, which gives instructions for installing Catalyst 12.6. This supported hardware list states that the 3670 is not supported in 12.6, and 12.4 must be used. This is somewhat confusing, as AMD's website suggests that the 12.6 driver should be installed for the 3670. There have been user reports that R600 (the GPU inside the 3670 card) doesn't work with 12.6, so I'm sticking with 12.4. I'm following these instructions to install the proprietary drivers on Lucid. I downloaded the 12.4 driver from the AMD website. Building the package worked fine, generating the fglrx, fglrx-dev, fglrx-amdcccle, and fglrx-modaliases deb packages successfully. However, when I try to install these using dpkg it gives me these errors. The make log referenced in the error is here. Ask Ubuntu References What is the correct way to install ATI Catalyst Video Drivers? Cannot install ATI/AMD FGLRX restricted graphic drivers Is my ATI graphics card supported in Ubuntu?

• Cannot connect Ubunto to Windows pc either direction

  - by Frank A

  New to ubuntu and really struggling with this. I want to connect to my old windows XP Pc on our home network. Searching for solutions gets complicated as at one level you are told use Connect to Server. I set to Windows Share, type in server IP address.. ... I get "Failed to retrieve share list from server" Demo on Youtube worked with no problem. Other advice in ask ubuntu is you need to install samba. Did that but nothing seems to happen when I try and run it other than it asking for admin password. (How do you tell what is running on Ubuntu?) So I try the other direction Windows XP to Ubuntu. I made the ubuntu directory within home frank shared and tried various combination such as \ipaddress\home\frank but just "The folder you entered does not appear to be valid. Please choose another." My entire data only drive is shared in Windows and no problems accessing that from other Win XP boxes on our network There are no alerts in Windows firewall, Ubuntu Firestarter did block but changed that to allowed... or so I thought. In firestarter I had set up Inbound traffic policy 192.168.1.1/24. And since then it has added the ip address of the win pc twice. So, I am in a state of confusion not knowing whedre to turn next so thought Ask Ubuntu :)

• Restart problem after installing graphical card driver

  - by Tim

  My laptop is Lenovo T400, running Ubuntu 10.10. My problem: I just run jockey-gtk and installed ATI/AMD proprietary FGLRX graphics driver. But after reboot, there is a short period of graphical "Ubuntu" and then instead of starting X-window it completely changed to command line to ask me to login. Even after login and then issuing xinit, it still failed to start X. To solve this problem: I followed this post, where one person suggested to you can simply write sudo apt-get remove fglrx This worked for me. If it doesn't work, then try sudo apt-get remove xorg-driver-fglrx and restart. I actually don't need the driver anyway, so I issued the first command after login under command line. But after reboot, the situation is even worse, and there is now even no command-line interface to ask me login, instead the screen is completely blank with just some ambient light in the background and Ubuntu is hanging there probably forever. So I have no chance to try the second command the person suggested. I was wondering what I can do now to solve my problem? Thanks and regards!

• I'm stuck on User Defined Session destop environment

  - by Dan

  I just installed Ubuntu for the first time dual boot so I get to choose Ubuntu or windows. I then changed the setting where is doesn't ask for my password when booting up. I then installed Edubuntu desktop package. I then hit system and logged out that way i could be at the loggin screen that also lets you select the desktop environment. Edubuntu was not there but User defined session was so i clicked that thinking that might be Edubuntu and logged in. Now im totally stuck. Only walpaper on the screen as i realize now that is normal for user defined session but there is no log out button to change desktop environments now and since I set it to not ask for password at boot up there is no option to change it at start up. If i hit ctrl+alt+del it only lets you shutdown, restart, suspend, or hybernate.... no logg out. I have hit every key on the keybourd hoping something will pop up. I thought this must be a simple noob mistake that there must be endless artiles about this so did searches on google and forums and was shocked to find nothing about this. My next step unless someone can help is to uninstall and reinstall.

• Interaction between two Clouds

  - by user7969

  I have setup the Cloud-A with 1 - [CLC+CC] and 2 - [NC] computers. I have another Cloud-B with same configuration. [using the Ubuntu Enterprise Cloud] Both of them working fine individually, in the same LAN. Now if I want to add the NC of Cloud-A to CC of Cloud-B, [in case the resources of Cloud-B are exhausted] how can I make it possible ? I guess this calls for the interoperability stuff... Could you please explain what happens exactly when we ask for instance, the direct interaction happens between the client and NC or it goes through the CLC and CC ? What I want to say is, say there are multiple cloud providers. A user is subscribed to any one of them, say Cloud-A for IaaS. As the requirements are dynamic, all the resources of Cloud-A may get exhausted. There may be another Cloud-B which can provide the services but that Cloud-A can't ask the client to go for Cloud-B. So if it is possible to have some co-ordination between this two providers to share resources mutually, making client fully unaware of whats going on in the background....? Please reply.. I am sorry if I'm doing mistake anywhere... Thanks in advance :)

• I want to be able to use the unity menu with Citrix full screen

  - by porec

  I use Citrix Reciever at work, with both XenApp and XenDesktop. Many times at the same time. Since the unity Menu stil apeirs on the top anyway, I'd like to be able to use it. Now I can see it, but it doesn't work.. I have to either tab me out, (double clicking the ALT first)opening another program first, or move the mouse to the left, opening another program from the unity menu from the left, BEFORE I can use the menu on the top.. (my menu on the left side is in autohide mode, so I actually like it :)) For example. I use spotify for lisening to music, it apeirs on the top menu, but it doesn't react when it click it.. I have to move the mouse to the left, open another program, then move to the top an ask it to show spofity. If I open spofify from the left menu, it hangs.. (since its hidden, and I have to ask it to be open, not reopen the hole program..) Or If I want to lock the screen, I have to open another program, (i.ex. nixnote) before I can lock it) since the unity menu is "on the top" anyways, I don't see the problem that it should be able to control such things..

• How do I daemonify my daemon?

  - by jonobacon

  As part of the Ubuntu Accomplishments system I have a daemon that runs as well as a client that connects to it. The daemon is written in Python (using Twisted) and provides a dbus service and a means of processing requests from the clients. Right now the daemon is just a program I run before I run the client and it sets up the dbus service and provides an API that can be used by the clients. I want to transform this into something that can be installed and run as a system service for the user's session (e.g. starting on boot) and providing a means to start and stop it etc. The problem is, I am not sure what I need to do to properly daemonify it so it can run as this service. I wanted to ask if others can provide some guidance. Some things I need to ask: How can I treat it as a service that is run for the current user service (not a system service right now)? How do I ensure I can start, stop, and restart this session service? When packaging this, how do I ensure that it installs it as a service for the user's session and is started on login etc? In responding, if you can point me to specific examples or solutions I need to implement, that would be helpful. :-) Thanks! Jono

• OSX: Why does an uninstalled program ask for inbound connections on login? How do I fix this?

  - by CT

  I uninstalled an application using AppZapper called PdaNet. It is a tethering application for my phone. Now every time I login, I am asked if I would like to allow inboud connections from PdaNet by the firewall. A search for PdaNet with spotlight does not return any results. PdaNet creates its own Ethernet in network preferences. This hung around after uninstall. I deleted it but it did not make a difference. Any ideas? Mac OS X 10.6.4

• CodeDOM: Adding DebuggerStepThroughAttribute to property

  - by Dont Ask

  I know how to add a DebuggerStepThroughAttribute to a method or a constructor, usually you add it to the CustomAttributes collection of a code member. But I don't see a way to do this for the setter and getter of a C# property, because neither of them provides this collection where you add the attributes. Does anyone have a clue?

• Change UIView alpha value

  - by Ask

  I'm trying to create an UIView and change its alpha property to simulate backlight change. Here is my code if (TransparentView == nil) { TransparentView = [[UIView alloc] initWithFrame:self.view.bounds]; TransparentView.backgroundColor = [UIColor whiteColor]; self.view = TransparentView; } start=start+appDelegate.OnOffTime; TransparentView.alpha = 0.2; float step = 1.0 / ( appDelegate.OnOffTime * 100); for (float f = 0; f < 1; f=f+step) { TransparentView.alpha = (CGFloat)(1 - f); [NSThread sleepForTimeInterval:0.01]; } Both TransparentView.alpha = 0.2 and TransparentView.alpha = (CGFloat)(1 - f) do change TransparentView.alpha, but only TransparentView.alpha = 0.2 changes real device "brightness'. What am I doing wrong?

• Can we call methods of non-static classes without an object in Java?

  - by ask

  In Java, the wrapper class Integer has the static method parseInt() which is used like this: Integer.parseInt(). I thought only methods of static classes could be called like this (ie. Class.doMethod()). All non-static classes need objects to be instantiated to use their methods. I checked the API, and apparently Integer is declared as public final Integer - not static. Someone please help me understand this.

• Set up two IP addresses with one gateway?

  - by Ahmed

  I would like to ask if it is possible to set up two static IPs from same subnet through one gateway? and How if it is? What I am interested in is described here Routing for multiple uplinks/providers, but in my case I have two IP addresses from one provider, both are on same subnet and off course I have internet access on both. I have two NICs, but I don't mind to go with one if that makes it possible. Any thought is appreciated!

• How to enable Moonlight?

  - by Ivan

  Even after I've installed all the Mono packages, I am still asked to install Silverlight when I visit Silverlight-enabled web pages. Even after I agreed to do this and installed the Moonlight Firefox extension from http://go-mono.com/moonlight/, nothing changed - Silverlight applets still don't work and ask to install Silverlight (directing to http://go-mono.com/moonlight/). How do I finally install it? The situation is the same in Ubuntu 10.10 and Xubuntu 11.04.

• How do you set up a ubuntu server so that it can recieve and run code remotely

  - by deadjaguars

  I've gotten my hands on two older (i.e. ~2 years old) department towers that I came across when setting up our new workstations that I want to turn into servers that people can run code on remotely. The code would mostly consist of Python (2 and 3) and Java. Being able to run those is a must, but other languages would be nice. I thought here would be a good as place as any to ask where I would start.

• Is there a difference between installing an application via Ubuntu Software Center or a terminal?

  - by gabriel

  I would like to ask a very basic question but I have never thought about it before. Well, when someone installs an application from terminal, he has to add the repository first, right? On the other side, when someone installs an application from the Ubuntu Software Center, is the repository then added automatically? I am asking those questions to figure out this: When I run update and then upgrade, will this application be upgraded or not? Is the result same in two options?

• Slow internet connection with mobile broadband

  I'm using a Huawei 156g USB stick to connect to the internet.

I'm not behind a proxy. please help, I just searched around ask Ubuntu and nothing matched my problem :-(

• Trouble with Wubi and dual boot install

  - by noam

  Is there a difference between wubi install and doing an install of Ubuntu alongside windows7? I ask because I used wubi, but I'm having trouble with certain things like being unable to change my brightness settings and I'm wondering if installing from a usb drive would change anything. Also, I've tried to do a usb drive install, but it doesn't give me the option to install alongside, it only shows the "Replace Windows 7" and "something else" options. Is this because I already did a wubi install?
