If you are quite happy with WebForms today, then maybe ASP.NET MVC isn't for you.

Quicksort has a better average case complexity but in some applications it is the wrong choice. Quicksort is vulnerable to denial of service attacks. If an attacker can choose the input to be sorted, he can easily construct a set that takes the worst case time complexity of o(n^2).

Use of composition instead of inheritance tends to be the way around this. This actually also helps a lot with testability, so it's good practice in general.

Have you considered using an EXE maker? For example, you can code in Python and use [py2exe](http://www.py2exe.org) to create a standalone EXE that runs anywhere (it actually packages Python into the exe, so you don't have to install the runtime). |

Writing complicated regular expressions for such jobs is a bad idea IMO. It's better to combine several simple queries. For example, first search for "\r\n\r\n" to find the start of the body, then run the simple regex over the body. |
I'm not sure of the syntax of C# regular expressions but you should have a way to anchor to the beginning of the string (not the beginning of the line such as ^). I'll call that "\A" in my example:

Yes, you can do a baseless merge, but only from the command line (tf.exe).

This behavior is caused by the different interpretations of the box model. The correct box model states that the width applies only to the content and padding and margin add on to it. So therefore your are getting 100% plus a 20px right and left padding equaling 100%+40px as the total width. The original IE box mode... |
The brackets can be used when column names are reserved words.
If you are programatically generating the SQL statement from a collection of column names you don't control, then you can avoid problems by always using the brackets. |
Column names can contain characters and reserved words that will confuse the query execution engine, so placing brackets around them at all times prevents this from happening. Easier than checking for an issue and then dealing with it, I guess. |
You can also define search groups with ld:
ld -r foo.o -( a.a b.a c.a -)
Will iterate through a.a, b.a, and c.a until no new unresolved symbols can be satisfied by any object in the group.

ld -r -o foo.o --whole-archive bar.a

I believe it adds them there for consistency... they're only required when you have a space or special character in the column name, but it's cleaner to just include them all the time when the IDE generates SQL. |

I believe that the fundamental reason that Java doesn't support multiple inheritance is the same as C#; all objects are ultimately derived from Object and it's having multiple paths to the same base class is ambiguous for the compiler. Ambiguous == Bad, so the compiler doesn't allow it.

Use whatever works for you. These are all easiest to set up if you already have a fairly normalized database (ie, good definition of primary keys and foreign keys). However, if you've got data that doesn't easily normalize, the Entity Framework is more flexible than LINQ to SQL, but it does take more work to configure. |
