TowTruck: a service for websites to collaborate in real-time

Posted on by

TowTruck is a service for your website that makes it surprisingly easy to collaborate in real-time.

TowTruck is incredibly easy to set up on your site.  All you need to do is include a couple lines of JavaScript and your site has TowTruck tools enabled.

When a user comes to your site, they’ll be able to activate the TowTruck tool and send a link to a friend to start collaborating on the web site.

TowTruck has collaboration features like cursor-mirroring (allowing you to see your friend’s cursor on the screen in real time), collaboratively editing forms and text, browsing through the site, and both text and real-time voice chat.

Disable the Toggle Completion Mode in Visual Studio

When writing code in Visual Studio, the shortkey Ctrl+Alt+Space toggles the completion mode of IntelliSense in the Text Editor.
The completion mode can be manually changed by going to this menu in VS2012:
EDIT > IntelliSense > Toggle Completion Mode

However the shortkey can be annoying while coding, depending on your keyboard configuration and language.

To disable this shortkey command in Visual Studio 2012 follow these steps:

  • Go to TOOLS
  • Select Options…
  • Go to Environment > Keyboard
  • Below the Show commands containing: type the word completion and hit the TAB-key
  • The filtered listbox should now contain a command called Edit.ToggleCompletionMode
  • Select it and hit the button Remove
  • Click OK to close the Options form

These steps are very similar to Visual Studio 2010.

SharePoint service not working after changing password and installing updates.

These steps will guide you in case you recently changed a password in Active Directory of an account that is used by SharePoint 2010 and you notice that your services are not working anymore.

For example, my search service stopped working:

“The search request was unable to connect to the Search Service.”

  1. Log in to the SharePoint 2010 Central Administration
  2. Under “System Settings” go to “Manage services on server”.
    Here you will find services that have stopped, because the password is wrong.
  3. If you try to start a service it is possible that you will receive a message that it doesn’t work,   because the passwords are different.

It is easy to fix this. Start the SharePoint 2010 Management Shell. Type in this command:

Set-SPManagedAccount -UseExistingPassword

It will ask for your identity (= username) and it will ask for the password of that account.

More information can be found here: http://technet.microsoft.com/en-us/library/ff607617(v=office.14).aspx

If you receive an error similar to

"Set-SPManagedAccount : Microsoft.SharePoint is not supported with version 4. of the Microsoft .Net Runtime. ..."

after entering the command. You might receive this message after installing recent Windows Updates.

  1. Go to the Windows start menu
  2. in the “Search programs and files” textbox from the Windows start menu search for SharePoint
  3. right mouse click on the “SharePoint 2010 Management Shell” and select “Properties”
  4. In the Target input box change this: 
    C:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe -NoExit  " & ' C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\CONFIG\POWERSHELL\Registration\\sharepoint.ps1 ' "

to (add -v 2 or -version 2)

C:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe -v 2 -NoExit  " & ' C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\CONFIG\POWERSHELL\Registration\\sharepoint.ps1 ' "

Now your SharePoint will start with another powershell version.

After changing your password you can go back to the SharePoint 2010 Central Adminitration and start your services with the new password (it is possible that you will have to enter your password again when starting the SharePoint service).

Reactive Extensions (Rx) was added to Codeplex.com:

The project is actively developed by the Microsoft Open Technologies, inc., in collaboration with a community of open source developers.

The Reactive Extensions (Rx) is a library for composing asynchronous and event-based programs using observable sequences and LINQ-style query operators. Using Rx, developersrepresent asynchronous data streams with Observables , query asynchronous data streams usingLINQ operators, and parameterize the concurrency in the asynchronous data streams usingSchedulers. Simply put, Rx = Observables + LINQ + Schedulers.

How to find out if your Linkedin password was found via PowerShell

Posted on by

First you need to download the combo_not.zip file and unpack it.
(for example read the comments on this post: http://tweakers.net/nieuws/82411/wachtwoorden-miljoenen-linkedin-gebruikers-op-straat.html )

Next drop the combo_not.txt file in your C:\ drive: C:\combo_not.txt

Now open PowerShell or PowerShell ISE and run the PowerShell script below:
(don’t forget to change YourPasswordHere):

cd c:\
$pass = "YourPasswordHere"
$sha1 = [System.Security.Cryptography.SHA1]::Create()
$bytes = [System.Text.Encoding]::UTF8.GetBytes($pass)
$hashArray = $sha1.ComputeHash($bytes)
$hashArray | foreach -Begin{$str=''} -Process{$str += "{0:x2}" -f $_} -End{$str}
$str2 = [String]::Concat("00000", $str.Substring(5))
findstr -I $str .\combo_not.txt
findstr -I $str2 .\combo_not.txt

I tested it and didn’t give a result, so that must be a good thing ;-) (let’s hope it is not due to this quick script :-) )

LinkedIn commented on the stolen passwords/hashes. Read it here: http://blog.linkedin.com/2012/06/06/linkedin-member-passwords-compromised/

Update: apprently the first 5 bits need to be set to 0 to do another check if it is hacked
Update2: updated the script
Update3: reply from LinkedIn

Please post a comment if there are any suggestions/mistakes.
