Visual Studio 2010 IntelliSense doesn't select a default value - it just marks it
...
@Tomas. Of course you do - all of the solutions above rely on that. Imagine if that didn't happen. You start typing the name of a variable, which in the first few letters could match several variables with similar names but different types, and ALL th...
Cannot set content-type to 'application/json' in jQuery.ajax
...S header is used to find out if the request from the originating domain is allowed. Using fiddler, I added the following to the response headers from my server.
Access-Control-Allow-Origin: *

Git stash twice
...
You can get a list of all stashes with
git stash list
which will show you something like
stash@{0}: WIP on dev: 1f6f8bb Commit message A
stash@{1}: WIP on master: 50cf63b Commit message B
If you made two stashes, then just call git stash pop...
Haskell: Lists, Arrays, Vectors, Sequences
...stant , aka purely functional, which is very nice. Haskell lists aren't really "lists" because they are coinductive (other languages call these streams) so things like
ones :: [Integer]
ones = 1:ones
twos = map (+1) ones
tenTwos = take 10 twos
work wonderfully. Infinite data structures rock.

Is there a way to make text unselectable on an HTML page? [duplicate]
...e. Likewise, I believe, with the querySelector API which I'm guessing typically hooks into the CSS/xpath selector engines directly. This may change over time as browsers find perf tweaks but I would definitely keep this in mind when supporting IE<=8, maybe <=9.

...
Convert to item pairs and check for containment.
all(item in superset.items() for item in subset.items())
Optimization is left as an exercise for the reader.

What is the point of Lookup?
... via that key in an efficient manner (rather than just iterating over them all, which is what GroupBy lets you do).
For example, you could take a load of .NET types and build a lookup by namespace... then get to all the types in a particular namespace very easily:
using System;
using System.Collec...
C# short/long/int literal format?
... // uint
var ul = 1UL; // ulong
var l = 1L; // long
I think that's all... there are no literal specifiers for short/ushort/byte/sbyte

Why do we need Abstract factory design pattern?
...
All of these examples describe the Factory Method Pattern, because all of them return a single product interface. None of these is an Abstract Factory Pattern, because none of them produce a family of related product interfac...
Why is lazy evaluation useful?
...epending on the sequence of conditional expressions, only a subset may actually be used. In a language like C, all three values would be computed anyway; but in Haskell, only the necessary values are computed.
It also allows for cool stuff like infinite lists. I can't have an infinite list in a lan...
