I must be doing something wrong, when installing it was very similar to these instructions
SQL Server has produced some excellent High Availability options, but I was looking for an option that would allow me to access my secondary database without it being read-only or in restoring mode. I need the ability to see transactions occur and query the secondary database.

In my quest to understand closures in the context of JS, I find myself asking why do you even need to use closures? What's so great about having an inner function be able to access the parent function's variables even after the parent function returns? I'm not even sure I asked that question correctly because I don't understand how to use them.
Can someone give a real world example in JS where a closure is more beneficial vs. the alternative, whatever that may be?

I have some DVD video discs that I am intending to sell. I would like to get information such as region, language, subtitles.
Some of the discs are in another language which I cannot read, and some are from small publishers and do not have such information on the disc or the boxes.
What methods can I use to access this information? Please list command line options, as well as common GUI based tools (eg VLC player).
In order to succeed in today's economy, organizations need to engage with information across all channels to ensure customers, partners and employees have access to the right information in the context of the business process in which they are engaged.

I have been looking at F# for a while now and seem a few really interesting samples and snippets on howto’s. This has been great to see the basic outline of the language and the possibilities, however a nagging question in the back of my mind has been what does an F# project look like? How do I code group code in F# so that it can be modularized and brought in and out of a project easily? My Expert F# book has an entire chapter (7) dedicated to this and after browsing the other chapters of the book I decided that this topic was something I really wanted to know more about now! Because of my C# background I keep trying to think in F# of objects. So to try and get a clearer idea of how to do things the F# way I am first going to take a very simplified C# example and try to “translate” it. using System;
namespace ConsoleApplication1
{
namespace ExampleOfEncapsulationInCSharp
{
class Program
{
static void EncapsulatedVariableInAMethod()
{
int count = 10;
Console.WriteLine(count);
}
static void Main(string[] args)
{
EncapsulatedVariableInAMethod();
Console.ReadLine();
}
}
}
}
From the above example the count integer is encapsulated within EncapsulatedVariableInAMethod method. You couldn’t access the count variable from outside the scope of its parent method but have full access to it within the method.
Lets look at my F# equivalent…
open System
let EncapsulatedVariableInAMethod =
let count = 10
Console.WriteLine(count)
()
EncapsulatedVariableInAMethod
Console.ReadLine()
Now, when I first attempted to write the F# code I got stuck… I didn’t have the Console.WriteLine calls but had the following…
open System
let EncapsulatedVariableInAMethod =
let count = 10
EncapsulatedVariableInAMethod
Console.ReadLine()
The compiler didn’t like the let before the count = 10. This is because every F# expression must evaluate to a value. If I did not want to make the Console call, I would still need to evaluate the expression to something – and for this reason the Unit Type is provided. I could have done something like….
open System
let EncapsulatedVariableInAMethod =
let count = 10
()
EncapsulatedVariableInAMethod
Console.ReadLine()
Which the compiler would be happy with…
I've just installed Banshee on Ubuntu 10.04 LTS, and manually imported 2 CDs. I needed to manually insert the track information as I haven't figured out how to access an online database. When I try to play track 17 from CD1, it always plays track 17 from CD2. The metadata should have been enough to differentiate between these tracks. How do I manually alter what is recorded in Banshee's database?

After following the instructions at: https://help.ubuntu.com/community/LiveCDCustomizationFromScratch; I installed xorg, gdm, and gnome. For some reason when I try to run it on both of my computers and qemu, it freezes up. Sadly I cant access a console to view all my logs, but I do have a dump of the boot process. I can also add and remove packages by ch-rooting into the compressed file-system.

From my understanding creating an application that runs on multiple architectures requires virtualization, and virtualization reduces performance since it creates a layer of abstraction.
With Windows 8 supporting both Intel and ARM architectures should we expect slower performance with a WinRT app versus a .Net app running on an Intel device?
Also, will WinRT support database connectivity and active directory access?
In the browser tools, say in debugging (any browser will do, but IE9 preferred) how can I access things like html5 canvas and modify individual pixels by typing commands from prompt ?
I know, it is possible to accomplish in miriad normal ways with preparing the markup and loading the page, but what is the shortest path ? The browser is running with some content, then I hit F12-Console- what exactly should I type to cause a canvas to change ? Thank you
I installed a WAMP package on a Windows 7 machine and everything ( Apache, php, mySql, phpMyAdmin) appear to have installed correctly.
However when I try to access localhost or phpMyAdmin via the browser, I get "Server Not Found". I've tried using localhost, 127.0.0.1 in the browser.
I've checked the httpd file it says "Listen 80". C:\Windows\System32\drivers\etc\hosts says "127.0.0.1 localhost"
Apache log file doen't show any errors.
Suggestions appreciated.
A different question of mine had to do with encapsulating member data structures inside classes. In order to understand this question better please read that question and look at the approach discussed.
One of the guys who answered that question said that the approach is good, but if I understood him correctly - he said that there should be a class existing just for the purpose of wrapping the collection, instead of an ordinary class offering a number of public methods just to access the member collection.
For example, instead of this:
class SomeClass{
// downright exposing the concrete collection.
Things[] someCollection;
// other stuff omitted
Thing[] getCollection(){return someCollection;}
}
Or this:
class SomeClass{
// encapsulating the collection, but inflating the class' public interface.
Thing[] someCollection;
// class functionality omitted.
public Thing getThing(int index){
return someCollection[index];
}
public int getSize(){
return someCollection.length;
}
public void setThing(int index, Thing thing){
someCollection[index] = thing;
}
public void removeThing(int index){
someCollection[index] = null;
}
}
We'll have this:
// encapsulating the collection - in a different class, dedicated to this.
class SomeClass{
CollectionWrapper someCollection;
CollectionWrapper getCollection(){return someCollection;}
}
class CollectionWrapper{
Thing[] someCollection;
public Thing getThing(int index){
return someCollection[index];
}
public int getSize(){
return someCollection.length;
}
public void setThing(int index, Thing thing){
someCollection[index] = thing;
}
public void removeThing(int index){
someCollection[index] = null;
}
}
This way, the inner data structure in SomeClass can change without affecting client code, and without forcing SomeClass to offer a lot of public methods just to access the inner collection. CollectionWrapper does this instead.
E.g. if the collection changes from an array to a List, the internal implementation of CollectionWrapper changes, but client code stays the same.
Also, the CollectionWrapper can hide certain things from the client code - from example, it can disallow mutation to the collection by not having the methods setThing and removeThing.
This approach to decoupling client code from the concrete data structure seems IMHO pretty good.
Is this approach common? What are it's downfalls? Is this used in practice?

I took 50 gigs of space and partitioned it off in windows. I then removed rights from any user with access to the computer as it is part of a domain. I'm not pc literate enough to know exactly which options to select in order to install ubuntu into the partition. I do not know which selections to make for the otions that are shown on the partition window during the installation process. If anyone could inform me how to correctly do this it would be much appreciated
