Add a new user to the permissions list. Enter "IIS AppPool\AppPoolName" on the local machine". Replace "AppPoolName" with the name of your application pool.

• Check your Embed Interop Types flag when doing Visual Studio extensibility work

  - by Daniel Cazzulino

  In case you didn’t notice, VS2010 adds a new property to assembly references in the properties window: Embed Interop Types: This property was introduced as a way to overcome the pain of deploying Primary Interop Assemblies. Read that blog post, it will help understand why you DON’T need it when doing VS extensibility (VSX) work. It's generally advisable when doing VSX development NOT to use Embed Interop Types, which is a feature intended mostly for office PIA scenarios where the PIA assemblies are HUGE and had to be shipped with your app. This is NEVER the case with VSX authoring. All interop assemblies you reference (EnvDTE, VS.Shell, etc.) are ALWAYS already there in the users' machine, and you NEVER need to distribute them. So embedding those types only increases your assembly size without a single benefit to you (the extension developer/author).... Read full article

• How do I list installed software with the installed size?

  - by Lewis Goddard

  I would like to have a list the installed software on my machine, with the disk space consumed by them alongside. I would prefer to be able to order by largest/smallest, but that is not a necessity. I am the sort of person who will install software to try it, and never clean up after myself. As a result, my 7GB (Windows and my Data are on separate partitions, as well as a swap area) Ubuntu 11.04 partition is suffering, and has started regularly showing warning messages. I have cleaned my browser cache, as well as everything under Package Cleaner in Ubuntu Tweak, and am left with 149.81 MB off free space.

• 12.04 - Connecting Acer X203H monitor to new Dell XPS 15z laptop

  - by Lucy Dixon

  I have installed the latest version of Ubuntu (12.04) on my boyfriend's new Dell XPS 15z laptop. He uses a Microsoft wireless keyboard and mouse, and an Acer X203H monitor with his set-up. No problems with the keyboard or mouse, or with connecting the HP printer, but we just can't get the laptop to talk to the Acer monitor. With his old setup he used a VGA cable to connect machine & monitor. New laptop has no VGA port, but we've bought a VGA to HDMI adaptor to connect to the laptop. Have tried using Fn F2 to change the display from laptop to monitor, but it doesn't see the monitor at all. HELP! Is there a driver I can install from somewhere? Or how can I tell Ubuntu to look for the monitor on another port? Completely in the dark, and about to get in trouble!! Thanks

• Submitting Java Code with Junit unit test

  - by LivingThing

  I have mostly work on simple java programs and compiled and run it with eclipse on Windows. So, i have no experience of using command prompt for compiling Java projects and do not have much info about what actually happens beneath the play button in Eclipse. Now i have to submit a Java application which will have basic operation on XML. My project also will have (JUnit) Unit Test. My question is related to submission of this Project. Which files would be necessary to submit the code. So, it executes properly? Does chosing eclipse as an IDE or junit as a unit testing framweork produces any dependenices i.e the executor of the program should have eclipse/libraries to execute the program on his machine?

  I have Ubuntu 10 as the guest OS on a Windows 7 machine. I have been trying to setup shares through VirtualBox, but nothing is working.

  I have Virtualbox 4.1.2_ubuntur3859 installed on an Ubuntu 11.10 host, running a guest ubuntu server 10.04 with xfce4 and xorg installed with no-install-recommends. I have installed guest additions, but the maximum resolution in the display settings is 800x600. I have read related questions: How to change resolution of the VirtualBox (Ubuntu guest and host)? Higher screen resolution in VirtualBox? upgrading VirtualBox 3.2.10 breaks my guest Ubuntu screen resolution Ubuntu as guest OS (with Vista host) stuck at 800x600 resolution but none contain the solution to my issue.

• How to run Ubuntu fully in initramfs?

  - by miernik

  I have a machine with 10 GB of RAM, and I would like to run Ubuntu on it (Debian also OK if its easier), fully in RAM in such a way: I boot from a compressed image on an USB flash disk, that is uncompressed into RAM, and then I can remove the disk from the USB slot, and use the system only with RAM, without any permanent disk. Whenever I make any changes that I want permanent, I would put the flash disk back into the USB slot (possibly not the same one as I used initially to boot, as I would like to keep many versions of the boot flash disk), and run some command that would save the current state into a compressed image on the disk. How can I set this up?

• Laptops or Notebooks in a meeting? [closed]

  - by greengit

  Is taking the laptop to the meeting a good idea? Of course, the project leader needs to have one -- but the programmers -- especially those who only need to get straight instructions on what to do next on the project -- do they need to take laptops? I feel it takes longer to save notes in a software -- and it's lot easier to just jot down "things to do" in a simple note book. That way you can keep up with the discussion and not lose track of what someone else is saying by spending too much time entering text in the machine.

• It is possible to hibernate an LXC container?

  - by Jo-Erlend Schinstad

  I know about lxc-freeze and lxc-unfreeze, but as I understand it, these simply pauses the container, similar to sending SIGSTOP and SIGCONT to a process. If I reboot the host, then the containers will cease to exist, right? I would really like a way to save state to persistent storage so that I could resume them at some later time, even the host is rebooted or something like that. I can achieve exactly what I want using VirtualBox by using the "Save machine state" mechanism, but if I could do it with LXC, it would be completely awesome.

• Is Ubuntu workable as a laptop for an IT consultant?

  - by Eric Wilson

  I work as a consultant programmer, typically in large businesses. I use a Windows Laptop, and many of my colleagues use a Mac. My personal preference would be to run Ubuntu if I could have complete control over my development environment. But I will have occasional need for Microsoft specific products, especially IE. My colleagues that use a Mac often run Windows on a virtual machine for these situations. My question is: Is Ubuntu a workable solution for the laptop of an enterprise programmer? For example, is it as easy to run Windows on a VM on Ubuntu as it is on a Mac? Has anyone out there tried this? Is there any particular reason why Ubuntu would not serve as well as a Mac for development in this environment? Note that I am not doing .NET development, so I am typically dealing with Java that is going to be run on an Apache server and used by clients running Windows.

• VirtualBox host: Ubuntu vs. Windows XP

  - by iambriansreed

  In order to lengthen the lifespan of my machine I am replacing the weakest link, the hard drive and installing a new OS. I had planned on using xp pro as my virtualbox host and ubuntu as guest. After messing with ubuntu desktop and server I am really impressed and am thinking of reversing the virtualbox setup; ubuntu host xp guest. I would use XP for Adobe Fireworks, Netflix, and iTunes (maybe) that's pretty much it. Any reason not to do ubuntu host with xp guest? I know the xp vbox will run slower as a guest but really how much slower? It's a desktop. 4gb ram, 500gb disk, Pent D 3.2 ghz

• Ubuntu on AMD based Sony Vaio VPCY B15AG

  - by Gaurav

  Last week I bought a AMD E350 (AMD Fusion platform) based Sony VAIO (VPCYB15AG) having AMD Radeon HD 6310 graphics, I removed Windows that came along with and installed Ubuntu 10.10 (AMD64) using USB drive. During installation my touchpad was not working, I managed through keyboard, but after completing installation & restarting the machine still there was no touchpad support. Also there's no proper graphic card drivers. Even I tried connecting the USB mouse to it but the left key is not working and had to configure the mouse as left-hand to get the left click enabled. I tried searching for any possible solutions for these but found nothing helpful, is there any hope? What should I do to enable i) enable touch pad support ii) get higher resolution 1366x768, etc?

• Is remmina 1.0 in the standard universe repositories?

  - by jackweirdy

  I just noticed that the copy of remmina I have on my machine (Running ubuntu 12.04) is 9.99.1 (This is up to date according to apt). The remmina website says that the most recent version is version 1.0 which uses FreeRDP. I'd like to use FreeRDP instead of rdesktop because of the improved MS RemoteApp support. To cut to the chase, is version 1.0 of remmina in the repos, or do I have to install it manually? (I've had a quick browse but haven't found anything). Added:

• How do I fix skype on x86 11.10 desktop which garbles audio both ways in connection with a Windows user?

  - by keepitsimpleengineer

  Strange phenomena ? I have a friend I connect with and talk to regularly occasionally using video. He runs Windows XP with a Logitech webcam and mike. I run Windows XP with a Logitech webcam and mike, and a laptop with built in webcam and mike running both 11.10 x86 Desktop and Windows XP Home. We gab and ogle fine with these. But when I installed 11.10 x86 with GNOME 3.2 dual boot on the same machine with the Logitech webcam and mike, whenever I try to ogle and gab the audio is total garbled. When I make a test call to skype or call somebody on a landline or cell - there's no problem. In summary, everything works except for when running 11.10 x86 GNOME 3.2 connected to his Windows XP. Stumped on this end.

• Can't connect VPN/add new VPN connection on 12.04 when using NX

  - by dbotamous

  I remote control my Ubuntu box using NX. I am trying to create a new VPN connection. I click on Configure VPN ? Add ? OpenVPN ? Create then I get a "Editing VPN connection 1" window but everything is grayed out, and I can't edit it. The only button I can click is Cancel. The reason I bring up NX is because if I plug in a monitor keyboard and mouse, I can create, edit import VPN connections just fine. So I imported all the different VPN connections, everything was fine. I then remoted back into the Ubuntu machine with NX, click on my VPN connection, and get VPN Connection Failed - The VPN CONNECTION failed to start. Not authorized to control networking. I then disconnected and reconnected NX, and now all the VPN connections I had imported are gone. Any ideas?
