• Managed Service Accounts (MSA) and Virtual Accounts

  Windows Server 2008 R2 and Windows 7 have two new types of service accounts called Manage Service Accounts (MSA) and Virtual Accounts.  These make long term management of service account users, passwords and SPNs much easier. Consider the environment at OrcsWeb.  As a PCI Compliant hosting company, we need to change all security related passwords every 3 months.  This is a substantial undertaking each time because of hundreds of passwords spread throughout our enterprise.  We...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Right click menu stopped working in firefox

  - by umpirsky

  Right click menu stopped working in firefox as well as address bar auto completion. I have tried removing and installing firefox again from software center, but the problem persist. UPDATE: Hehum, strange. I wanted to restart in safe mode, clicked help menu, and noticed that menu is ubuntu software center menu! Then cllosed software center, and menu was gone. So now right click is working, auto complete is working, but there is no main menu! Probably unity global menu integration problem. Also, there is no firefox in launcher nor alt+tab any more. Any idea? UPDATE: For some reason, it works after computer restart :o

• Purple screen on boot, iMac

  - by Eugene B

  I have just installed Ubuntu 13.10 (special iMac iso found here) on the new iMac (dual boot). Installation of rEFIt was completed successfully, as well as the installation of Ubuntu itself. After the final reboot, rEFIt sees this distributive and allows the choice. When I select "Boot linux from HD", it sends me to grub screen, where I can select Ubuntu. And then it gets stuck on the purple screen (smpboot: Booting Node 0, Processors #1 -- for the recovery mode) with no further action. Does anybody know a solution to this problem? P.S.: I have also tried both 32 and 64-bit pc distributives (occasionally) with the same result.

• adverising servers / advert delivery solutions for C#/Asp.Net

  - by Karl Cassar

  We have a website which we want to show adverts in - However, these are custom adverts uploaded by the webmaster, not the Google adverts, or any adverts the network chooses. Ideally, there would be both options. We were considering developing our own advert-management system, but looking at the big picture, it might be better to consider other alternatives. Website is currently developed in C# / ASP.Net (Web Forms) Are there any recommendations to some open-source delivery networks and/or external hosted advert delivery networks? Personally I've used Google's DFP, however sometimes it is not so easy to get a Google AdSense account approved, especially while developing a new website and it not yet being launched. Not sure if this is the best place to ask this kind of question!

• How can I create a solid business case for upgrading our programmers to 256 GB SSD and 16 GB of RAM?

  - by Alex. S.

  We have an environment based on Microsoft stack (VS2010, SQL Server, etc), and I firmly believe that we could improve productivity a little bit, having more RAM and a faster secondary SSD. What data do you advice to gather so I can solidify my request in such a way the advantages can be unbiasedly demonstrated? Currently we have only 6GB of RAM and slower HD drives, and at home I have a 128 GB SSD in my desktop and 16 GB of RAM (I also think is the max amount of memory supported by our workstations, if we could go bigger then better), so I can feel the difference and it's real. I also want to add that we are in an industry with plenty of money, so the issue actually is how to get a budget approval from management and spend it wisely to increase productivity.

• How to reset settings when Unity won't finish booting?

  - by Emre

  I have a new 12.04 installation and I messed things up after trying to move /home to an NTFS partition, which I later learned was a bad idea. I removed references to the NTFS partition on fstab and created new users on the ext4 / partition. Now I can't get Unity to start up properly for any user. I get the GUI with only three Launch icons (none of which are clickable) and no bar at the top. The keyboard seems to the nonfunctional after I enter my credentials. The interesting thing is that I can boot when I go through recovery mode and select resume. I wonder whether I am creating the new users properly. What is the correct protocol for doing so in order to ensure that they can run Unity?

• How can I disable Hibernate completely?

  - by Lekensteyn

  I have seen the answer on How to disable hibernating?, but I have no such file. Possibly because that suggestion was written for Ubuntu, not Kubuntu (KDE, not Gnome). I do not have a swap on my encrypted SSD, my system freezes (cannot even change Caps Lock) if I accidentally press the "Hibernate" button at "Energy management". My keyboard has a Hibernate button (Fn + F4) next to the volume control buttons and every time I press the wrong key, the system will freeze after. So, what is the correct way to disable it? If there is no solution, a work-around is welcome too.

• Resetting Google's data for the website

  - by Giorgi

  I own a domain which I was using for experimenting with different platforms and content management systems. I really did not care about seo while I was building the website so I guess my website has quite a 'bad reputation' for Google search. My website is almost finished and I am planning to launch it soon but would like to tell Google to forget everything it nows about it and start everything over. What's the correct way for doing it? I found Requesting reconsideration of site but I'm not sure if that's the best way to do it. Any advice?

• Effective template system

  - by Alex

  I'm building a content management system, and need advice on which theming structure should I adopt. A few options (This is not a complete list): Wordpress style: the controller decides what template to load based on the user request, like: home page / article archive / single article page etc. each of these templates are unrelated to other templates, and must exist within the theme the theme developer decides if (s)he want to use inner-templates (like "sidebar", "sidebar item"), and includes them manually where (s)he thinks are needed. Drupal style: the controller gives control to the theme developer only to inner-templates; if they don't exist it falls back internally to some default templates (I find this very restrictive) Funky style: the controller only loads a "index.php" template and provides the theme developer conditional tags, which he can use to include inner-templates if (s)he wants. Among these styles, or others what style of template system allows for fast development and a more concise design and implementation.

• Fails to boot after upgrade, stuck on winbind package

  - by Praetorian

  I started the upgrade from 11.04 to 11.10 last night. Once it got the installing packages part I left the computer unattended the rest of the night. When I checked it this morning the screen was blank and I couldn't get it to turn on. So I cycled power, and now I get the "Ubuntu 11.10" screen with the dots underneath, but then it gets to a blank screen and nothing more. I can get to the command line in recovery mode; here's a list of the things I've tried so far sudo apt-get update - the very first repository it checked sat at 0% for a long time (network cable is plugged in), so I cancelled with Ctrl+C Thought it might be a problem with display drivers, so I tried sudo apt-get install nvidia-glx - this gave me an error saying dpkg has been interrupted, manually run sudo dpkg --configure -a sudo dpkg --configure -a this installed / updated a bunch of stuff but got stuck at Starting Winbind daemon winbind Restarted and tried sudo dpkg --configure -a again but it gets stuck at same Windbind step What else can I do to fix this problem?

• Changes to File Store Provider in UCM PS3

  - by Kevin Smith

  In the recent PS3 release of UCM (11.1.1.4.0) there are some significant changes to the File Store Provider (FSP) configuration. For new PS3 installs (not upgrades from PS2) the FSP default storage rule includes a dispersion rule that will change the web-layout and vault paths by adding dispersion directories to the paths to limit the number of files in the vault and web-layout directories. What that means is that if you install a new PS3 UCM instance and migrate content in from a previous version of UCM the web URL will change. That is a critical problem for web sites and just general document management. See below for some details on the FSP configuration in PS3 and how you can change the default behavior. use the link below to read the rest of this post where I describe the issue in detaill and provide instructions for how to modify a PS3 instance to use the old format for the web-layout path.

• How do I turn on wireless adapter on HP Envy dv6 7200 under Ubuntu (any version)?

  - by Dave B.

  I have a new HP Envy dv6 7200 with dual boot Windows 8 / Ubuntu 12.04. In windows, the F12 key in Windows activates the "airplane mode" switch which enables/disables both on-board (mini PCIe) and USB wireless adapters. In Ubuntu, however, the wireless adapter is turned off by default and cannot be turned back on via the F12 key (or any other combination of F12 and Ctrl, Fn, Shift, etc.). Let me explain the "fixes" I've seen in various forums and explain what did or did not happen. These are listed in no particular order. (Spoiler alert: wireless is still broke). Solution 1? Use HP's "Wireless Assistant" utility to permanently activate the wireless card in Windows, then boot into Ubuntu to happily find it working. Unfortunately, this utility works in Windows 7 but not Windows 8. On the other hand, hardware drivers from HP are only available for Windows 8 for this model. Catch 22 (I could not find a comparable utility for Windows 8). Solution 2? Use a USB wireless adapter to sidestep the on-board device. I purchased such a device from thinkpenguin.com to be sure that it would be Linux-friendly. However, the wireless switch enables / disables all wireless devices including USB. So, there's my $50 donation to the nice folks at thinkpenguin.com, but still no solution. Solution 3? Following the Think Penguin folk's suggestion, modify the mini PCI express adapter following instructions here: http://www.notebookforums.com/t/225429/broken-wireless-hardware-switch-fix Tempting, but I then violate the terms of my warranty mere days after opening the box. This might be a good solution for an older machine that you want to get your geek on with, but not for a new box. Solution 4? rfkill unblock all No effect whatsoever. ubuntu@ubuntu-hp-evny:~$ rfkill unblock all ubuntu@ubuntu-hp-evny:~$ rfkill list all 0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Solution 5? Re-install drivers. Done and done. Ubuntu recognizes the device - perhaps even without re-installing the drivers? - but cannot turn it on. How do I know this? In the Network Manager drop-down menu, the wireless option is blacked out and a message reads something like: "wireless network is disabled by a hardware switch". Solution 6? Identify a physical switch on the laptop and flip it. There is no such switch on this machine. In fact, walking through Best Buy yesterday, I checked and not a single new laptop PC had a physical switch on it. All of the wireless switches are either the F2 or F12 key ... I wonder if askubuntu will not be plagued by this exact issue in the near future?

• Compelling Reasons For Migrating to Oracle Database 11g

  - by margaret hamburger

  IDC's white paper Maximizing Your Investment in Oracle Application Software: The Case for Migrating to Oracle Database 11g  describes compelling business, operational, and technical reasons for Oracle application customers to upgrade or Oracle Database 11g. In researching this paper, IDC found that the upgrade process is smooth, the latest version offers key benefits over older versions, and the new features and procedures are easy to learn and well worth implementing. The paper highlights users of Oracle applications, such as Oracle's PeopleSoft Enterprise applications, Siebel Customer Relationship Management (CRM) applications, and Oracle E-Business Suite. It includes a review of Oracle Database 11g improvements and new features along with best practices from Oracle users who upgraded to Oracle Database 11g.

• How would I get work as a PHP, MySQL Developer?

  - by Matthew

  I've been working with PHP and MySQL to create various projects that I've been interested in, I can design the user interface, and the back end programming. I've created simple social networking sites, book marking sites, and project management software. So what steps would I take to get a job? Is there a market for PHP, MySQL web developers? Is it possible to take instructions and work from home for someone? How would I accept payment? Should I start a company? or work for someone? I am currently based in South Africa, many of the companies are lacking the innovation that I'm seeking for in a company.

• Ubuntu installer doesn't see internal hard drive on DELL Vostro 3360

  - by valk

  I just received a new DELL Vostro 3360, it has Windows 7 preinstalled. When it comes to the partition window I can't see the hard drive there. I see only /dev/sda or /dev/sdb (either one and in both cases it's a usb drive from which I'm installing). I tried every imaginable BIOS configuration. Tried to change the SATA mode to ATA, DHCI and more. EDIT: I tried to install with standard Ubuntu 12.04 32 bit, and 11.10 64 bit official versions. No luck. I'll appreciate any suggestion.

• How to install Visual Python?

  - by user214152

  I'm a Linux newbie but I'm determined to get my favorite applications on my laptop running Ubuntu 12.04. I just installed Cinnamon. I'm trying to install Visual Python and it requires Python 2.7. I followed the instructions on the VPython site but the Wine application isn't extracting anything from the Python .msi file. From the first line wine start /i python-2.7.5.amd64.msi /qn TARGETDIR=~/Python27 ALLUSERS=1 it says fixme:storage:create_storagefile Storage share mode not implemented. I created that Python27 directory so I know it exists and it's empty. I know Ubuntu already has Python 2.7 so I just tried running the VPython.exe file but it says "This program can only be installed on versions of Windows designed for the following processor architectures: x64." My Toshiba satellite has a 64-bit processor. Could anybody help?

• MTP Won't Work With Newer Ubuntu

  - by spacesword

  I have a Philips GoGear Vibe 4 GB, set to MTP mode, as it's always been. This works fine with older versions of Ubuntu and works fine with Windows, but doesn't work with newer versions of Ubuntu. The version history is like this: 12.04 - works 12.10 - works 13.04 - doesn't work 14.04 - doesn't work Windows 7 - works When you plug the MP3 player in Ubuntu the file manager opens the root of the device, which contains the folder "internal storage". When you click on "internal storage" to open it, the file manager just hangs. And if you try to unmount the MP3 player, that process hangs too, until you just unplug it. In Windows when you click on internal storage, it opens and shows all the files it contains. And in the earlier versions of Ubuntu it just worked. Any ideas? Thanks.

• Vdpau performance in Precise with Unity 3d

  - by bowser

  vdpau seems to be broken in Precise under Unity 3d. CPU usage ranges around 50-70% for 1080p movies while same movies utilizes around 5-10% in Natty with vdpau enabled (under Unity3d) The card is Nvidia G105m. It doesn't seem to be a Nvidia driver problem because in gnome-shell everything works as expected and I have tried different versions of Nvidia drivers (295.20, 295.33, 295.40 and the latest 302.XX from xorg-edgers) The results are all the same, works in Gnome Shell but not in Unity 3d. Disabling syn to vbank works if movie is not in full screen mode, but it doesn't work for full screen. I have searched around and haven't found much info. I am wondering if others are experiencing the same problem and if there are some known work around that I have missed. Unity 3d is otherwise very nice in Precise, but this is a show stopping issue for me (literally). Thanks. I have filed a bug here https://bugs.launchpad.net/unity/+bug/993397
