• Secure Yourself by Using Two-Step Verification on These 16 Web Services

  - by Chris Hoffman

  Two-factor authentication, also known as 2-step verification, provides additional security for your online accounts. Even if someone discovers your password, they’ll need a special one-time code to log in after you enable two-factor authentication on these services. Notably absent from this list are banks and other financial institutions. It’s a shame that you can use two-factor authentication to protect your in-game currency in an MMORPG, but not the real money in your bank account.

• Why does a bash-zenity script has that title on Unity Panel and that icon on Unity Launcher?

  - by Sadi

  I have this small bash script which helps use Infinality font rendering options via a more user-friendly Zenity window.

• how to set owner and permission to a cryptsetup made device?

  - by Antoine Rodriguez

  I have an encrypted loopback volume. I need to mount and umount manually the volume so I use cryptsetup luksOpen and cryptsetup luksClose . However, When I invoke this command it pops up the /dev/mapper device under all the sessions under gnome/xfce/kde/unity ... And then it let the user to mount (with password), expulse and unmount the volume. It's quite annoying in a multi user server (you are working on your files and the volume is being unmounted). How can I define ownership and permission on the device ? I've tried chown and chmod approach witch gives nothing. Cryptsetup doesn't have any options that let you do that. crypttab auto mount the filesystem on boot witch is unwanted (only manual mount)

  - by anthonypliu

  I was planning on logging a lot of different stuff in my production environment, things like when a user: Logs In, Logs Off Change Profile Edit Account settings Change password ... etc Is this a good practice to do on a production enviornment? Also what is a good way to log all this. I am currently using the following code block to log to: public void LogMessageToFile(string msg) { System.IO.StreamWriter sw = System.IO.File.AppendText( GetTempPath() + @"MyLogFile.txt"); try { string logLine = System.String.Format( "{0:G}: {1}.", System.DateTime.Now, msg); sw.WriteLine(logLine); } finally { sw.Close(); } } Will this be ok for production? My application is very new so im not expecting millions of users right away or anything, looking for the best practices to keeping track of actions on a website or if its even best practice to.

• Xubuntu dual monitor broke display

  - by Arman yaraee

  After I used Settings Display to enable my second monitor, my first display is not working anymore either. So I enabled both, then clicked save configuration since it was working and boom it crashed. Now when I start up, I can see the screen which I type my password but it goes black after that! When I boot into recovery mode it works fine but in Settings Display I don't see HDMI at all to disable it. Is there anyway to restore all display setting to default? (I can Ctrl+ALT+F1 and type commands but xrandr returns no results over there) EDIT I should clarify that system bios is set to laptop display

• Recycle Old Hardware into a Showcase Table

  - by Jason Fitzpatrick

  If you have a plethora of old hardware laying around, especially motherboard and expansion cards, this obsolete-hardware-to-table hack is just the ticket for your office or geek cave. The table’s design is simple. They took a regular coffee table, affixed old mother boards to it and then, over the motherboards and elevated by acrylic standoffs, they put a heavy sheet of acrylic to serve as the table top. You could replicate the design with any sort of old hardware that is interesting to look at: memory modules your company is sending off to be recycled, old digital cameras, mechanisms from peripherals headed for the scrap heap, etc. Hit up the link below to see more photos of the table.

• Self hosted Netvibes alternative [on hold]

  - by Jens

  I am looking for a self-hosted alternative to part of the Netvibes functionality. It should act as feed reader, show my mail inbox, a list of bookmarks and maybe the weather forecast. I wish to move away from Netvibes since I don't care to share my browsing habit, and certainly not my mail password, with another person or company. I am certainly willing to invest some time in setup, maybe up to writing a plugin for a solution that does not fulfill all my requirements. Dou you have suggestions on where to look?

• Black & White screen after resuming from Suspend [Ubuntu 12.04]

  - by Rakatash

  I recently thought of giving Linux a try with Ubuntu 12.04. So far I managed to figure out how to troubleshoot and fix some of my older issues. But i wasnt able to find a problem similar to mine. The issue is, whenever my laptop starts up after suspend, the screen stays black for a short while. then after that comes a black and white 8-bit kinda screen with nothing else. I am not sure if it's an issue with the graphic card or not. because I am able to write my login password and proceed normally if i wait till this screen shows up...after that everything is displayed normally. is there a fix for this?

• IValidatableObject vs Single Responsibility

  - by Boris Yankov

  I like the extnesibility point of MVC, allowing view models to implement IValidatableObject, and add custom validation. I try to keep my Controllers lean, having this code be the only validation logic: if (!ModelState.IsValid) return View(loginViewModel); For example a login view model implements IValidatableObject, gets ILoginValidator object via constructor injection: public interface ILoginValidator { bool UserExists(string email); bool IsLoginValid(string userName, string password); } It seems that Ninject, injecting instances in view models isn't really a common practice, may be even an anti-pattern? Is this a good approach? Is there a better one?

• 8 Ways to Tweak and Configure Sudo on Ubuntu

  - by Chris Hoffman

  Like most things on Linux, the sudo command is very configurable. You can have sudo run specific commands without asking for a password, restrict specific users to only approved commands, log commands run with sudo, and more. The sudo command’s behavior is controlled by the /etc/sudoers file on your system. This command must be edited with the visudo command, which performs syntax-checking to ensure you don’t accidentally break the file. HTG Explains: What Is Windows RT and What Does It Mean To Me?

• Is there a solution for SugarCRM that can map roles or privileges to Active Directory groups?

  - by Cory Larson

  We're presenting SugarCRM as an option to one of our clients, but they want to drive permissions within Sugar by users' AD groups. Current LDAP integration with SugarCRM only does password management. Does anybody know of a plug-in that supports this? I've searched and have not been able to find anything. Has anybody change the LDAP module code within Sugar to accommodate these features? I'd be interested in chatting with you. I apologize if this isn't on the correct site; neither serverfault nor stackoverflow seemed like the correct place. Perhaps webapps? Thanks!

• How to Encrypt Your Home Folder After Installing Ubuntu

  - by Chris Hoffman

  Ubuntu offers to encrypt your home folder during installation. If you decline the encryption and change your mind later, you don’t have to reinstall Ubuntu. You can activate the encryption with a few terminal commands. Ubuntu uses eCryptfs for encryption. When you log in, your home directory is automatically decrypted with your password. While there is a performance penalty to encryption, it can keep private data confidential, particularly on laptops that may be stolen. HTG Explains: What Is RSS and How Can I Benefit From Using It?
