Add SSRS (SQL Reporting Services) to an existing SQL Server Clustered Instance
To add a SSRS feature to already installed SQL server cluster it's necessary to bypass checking HasClusteredOrPreparedInstance rule before running setup file otherwise the unstallation will encounter with error during "Installaation Rules" check with some popup message like following:

To avoid above mentioned error it's possible to run setup as following:
SSRS (Reporting Services), Scale Out, Clusters, or NLB, ...
The question around installing Reporting Services as part of a SQL Cluster install with attention to the fact that SSRS is not cluster aware and utilizing NLB if you want to do it (even though it's not recommended) ended up in the following URL which I would like to share here.

How to find out installed features on SQL server instance
The SQL Server Setup Discovery Report helps to view installed features on a local SQL server instance,
Start menu --> All Programs --> Microsoft SQL Server --> Configuration Tools --> SQL Server Installation Center --> Click the "Tools" --> "Installed SQL Server features discovery report"
The command line version would be like the folowing:
setup.exe /ACTION=RUNDISCOVERY /Q
The setup.exe is located somewhere like (for MS SQL Server 2012):
C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\SQLServer2012
The report will be located in log folder under "Setup Bootstrap" in a unique subfolder which will be named as YYYYMMDD_HHmmSS, but the location can be vary depend on installation location:
C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\Log\YYYYMMDD_HHmmSS

SSRS Line Spacing
LineHeight property of Textbox control works just when the report renders in HTML format, to control line spacing in a Multi line textbox which carries a long text who handles auto text wrap up doesn't functions correctly.

JavaScript - Calling function "statements" before definition
function statements get interpreted and will be added to the execution stack before code execution then that's the reason but have attention that it doesn't happen to neither function expressions nor functions which define by Function constructor.
<!DOCTYPE html><html lang="en"><body><script>
// logs 11
console.log(aFunc(1, 2, 3));
function aFunc(x, y, z) {
return x*y + arguments[0]*arguments[1]*arguments[2]
};
// logs "Uncaught TypeError: ..." console.log(iFunc(1, 2, 3)); var iFunc = function (x, y, z) { return x*y + arguments[0]*arguments[1]*arguments[2] };
// logs "Uncaught TypeError: Property 'bFunc' of object [object Object] is not a function" console.log(bFunc(1, 2, 3)) var bFunc = function (x, y, z) { return x*y + arguments[0]*arguments[1]*arguments[2] }; </script></body></html>

Non-primitive [false] Boolean object is actually [true]
A Boolean object with false parameter (not the primitive false value) which generated from the Boolean() constructor, the object value will be true to check you may use it in an "if" condition.
If a value is false, undefined, null, NaN, 0, -0, or an empty string(""), it is false! but any other value in JavaScript will be converted to true if used in a Boolean context.

JavaScript - references to object properties
if the property of an object which you try to access is not available, JavaScript will try searching the prototype chain. At first steps it goes after the constructor function that created the object to check its prototype (e.g., Array.prototype) and if that's not available there it keeps searching up the chain at the constructor behind the initial constructor.
As all those prototype properties are objects, the final step would be Object.prototype because there is no other constructor prototype property upper than Object level to be examined.
Anyway if finally JavaScript can't find the property it would have produced an error stating that the property was undefined.

Javascript console.log for web browsers
Javascript console.log for web browsers
by console.log you may view any output message, other debugging tools or plugins can be utilized too for this purpose which are generally better as they provide rich features for debugging (e.g Firebug, ...).
To open the console window the following keywords work depend on the web browser:
console window

Enable/Disable - SSRS Export Types
SSRS supports exporting to different formats when you view the report through a drop-down list. Report services server configuration file which is available in the following path allows to control the list:
C:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer\rsreportserver.config
Inside the <Render> tag elements, the Extension names have Visible attribute which changing them to true will make the Extension visible in the Export list.
Example:
