Add default syntax highlighting for the [dart] tag I just approved several edits from a user adding  to questions with the  tag. Apparently , Google Code Prettify has added support for Dart.  I suggest it's time to follow suit and update the default syntax highlighting associated with the  tag. Adding it manually to every question sounds like way too much work, even if I all I have to do is click the "Approve" button. This is a follow up from this .  I'm using this slightly modified script to enumerate all installed MSI packages:  strComputer = "."  Set objWMIService = GetObject("winmgmts:" &amp; _     "{impersonationLevel=impersonate}!\\" &amp; _     strComputer &amp; _     "\root\cimv2")  Set colSoftware = objWMIService.ExecQuery _     ("SELECT * FROM Win32_Product")     If colSoftware.Count &gt; 0 Then     For Each objSoftware in colSoftware         WScript.Echo objSoftware.Caption &amp; vbtab &amp; _         objSoftware.Version     Next Else     WScript.Echo "Cannot retrieve software from this computer." End If   What is surprising however, is its abysmal performance. Enumerating the 34 installed MSI packages on my XP box takes between 3 and 5 minutes !  By comparison, the Linux box that sits besides is taking 7s to enumerate 1400+ RPMs... sigh  Any clues on this ? Which shell interpreter runs a script with no shebang? Suppose the default shell for my account is zsh but I opened the terminal and fired up bash and executed a script named prac002.sh, which shell interpreter would be used to execute the script, zsh or bash? Consider the following example:  papagolf@Sierra ~/My Files/My Programs/Learning/Shell % sudo cat /etc/passwd | grep papagolf [sudo] password for papagolf:  papagolf:x:1000:1001:Rex,,,:/home/papagolf:/usr/bin/zsh # papagolf's default shell is zsh  papagolf@Sierra ~/My Files/My Programs/Learning/Shell % bash # I fired up bash. (See that '%' prompt in zsh changes to '$' prompt, indicating bash.)  papagolf@Sierra:~/My Files/My Programs/Learning/Shell$ ./prac002.sh  Enter username : Rex Rex # Which interpreter did it just use?   **EDIT : ** Here's the content of the script  papagolf@Sierra ~/My Files/My Programs/Learning/Shell % cat ./prac002.sh  read -p "Enter username : " uname echo $uname Initializing Manipulator value within DialogInput (version 10.1 only) A great Python IDE for Ubuntu What else can you do in the turn you ready an action? Unknown site on Android app When I select the unknown site (i.e. the meta sites) the app crashes.   I have a Samsung Note 5 and version 1.0.89 of the app. A singularity, by the definition I know, is a point in space with infinite of a property such as density.  Density is Mass/Volume.  Since the volume of a singularity is 0, then the density will thus become infinite because Mass/0 = undefined  However, is it possible to have a singularity with a mass of 0? 0/0 is indeterminate, but would it be possible for a singularity to exist even if its mass and volume were zero?

ISP blocking port 25 My ISP has started blocking port 25 so I can not send email through my dedicated server any more.   I have several options:   Send email through the SMTP server provided by my ISP. Any problems with this? Setup mu server so that it receives email on another port instead of port 25     No one else sends email through my server so it should be OK. How do I do this on a Linux server?
