In Matlab, when is it optimal to use bsxfun?
...sons bsxfun is faster: (1) the calculation happens in compiled code, which means that the actual replication of the array never happens, and (2) bsxfun is one of the multithreaded Matlab functions.
I have run a speed comparison between repmat and bsxfun with R2012b on my decently fast laptop.

How to cherry-pick from a remote branch?
... object xxxxx
that's because you don't have access to that commit. Which means you don't have that repo stored locally. Then:

What do the different readystates in XMLHttpRequest mean, and how can I use them?
...you to read the partial data.
readyState 4 is the only one that holds any meaning.
(*: about the only conceivable use I can think of for checking for readyState 3 is that it signals some form of life at the server end, so you could possibly increase the amount of time you wait for a full response ...
Html.Textbox VS Html.TextboxFor

<input id="Name" name="Name" type="text" />
So what does that mean in terms of use?
Generally two things:
The typed TextBoxFor will generate your input names for you. This is usually just the property name but for properties of complex types can include an underscore such as 'custome...
Add property to anonymous type after creation
...
I assume you mean anonymous types here, e.g. new { Name1=value1, Name2=value2} etc. If so, you're out of luck - anonymous types are normal types in that they're fixed, compiled code. They just happen to be autogenerated.

It means "all documents except those without a name (either non existant or empty array) or with just one name."

LPCSTR, LPCTSTR and LPTSTR
...he first part of your question:
LPCSTR is a pointer to a const string (LP means Long Pointer)
LPCTSTR is a pointer to a const TCHAR string, (TCHAR being either a wide char or char depending on whether UNICODE is defined in your project)
LPTSTR is a pointer to a (non-const) TCHAR string

A python class that acts like dict
...nstead of simply delegating to the instance's __dict__ - which essentially means you're creating two dicts for every instance.

Difference between fold and reduce?
...he first element of the input list as the initial accumulator value.
This means the accumulator and therefore result type must match the list element type, whereas they can differ in fold as the accumulator is provided separately. This is reflected in the types:
List.fold : ('State -> 'T -> ...
What does $NON-NLS-1$ mean?

NON-NLS means Non-National Language Support.
Wikipedia proposes also Non-Native Language Support (NLS) but this last one is not very used.
NLS is about internationalizing your application. Eclipse help to locate hard-coded strings i...
