Assume we have an array of objects of length N (all objects have
the same set of fields).

And we have an array of length N
of the same type values, which represent certain object's field (e.g.
array of numbers representing IDs).

Now we want to sort
the array of objects by the field which is represented in the 2nd
array and in the same order as in the 2nd array.

example, here are 2 arrays (as in description) and expected

A = [ {id: 1, color: "red"}, {id: 2, color:
"green"}, {id: 3, color: "blue"} ]
B = [ "green", "blue",
sortByColorByExample(A, B) ==
[ {id: 2,

Given a single .net codebase for a piece of software (let's use C#
for argument's sake), and I want to break this software down into
different editions based on functionality (like a basic edition and an
advanced edition), what is the best way to go about this?


Would I have to factor this into my software architecture?

I am new to code igniter and MVC PHP, I have created a basic login
system with online resources and it works, I am now trying to improve
it to learn ...

my model:


$query =

if($query->num_rows == 1){
return true;

function get_admininfo(){


I do this a lot: [M-%] to query-replace,
then hit [y] a few times, then I'm past the area where
I'm changing things so I hit [q] to be done.


Then I'd like to get the cursor back to where I was, so here's
where it gets awkward. I [C-_] to undo the
last replace, then move the cursor on character, then
undo again to redo the last replace. Now the cursor's up
where I've been editing, but there has to be a better way.


(I'm happy to get back to either where I started the replace, or
where the last replace happened.)

How to efficiently program in Emacs ESS-mode the key

Just like the MacOS version of R utilizes.

The AppleScript standard suite has a command that will print from
an application, allowing for the specifying of certain options and
printing without displaying a dialog box. For example:

/>tell application "Safari"
print document 1 with
properties {copies:3} without print dialog
end tell />

However, there appears to be a bug in the current
version of Safari that prevents this from happening like it's supposed
to.1 When specifying without print dialog, a sheet pops
up in the window that should display progress in processing the print
job, but instead of doing so it just hangs with a nondescriptive

I have removed the PrimaryKey from my table, refreshed the EDMX,
and now I am getting this error message when doing

Unable to update the EntitySet 'Results'
because it has a DefiningQuery and no element exists in the element
to support the current operation.

1 - I dont
want PrimaryKey in my table. The table is just a bag of values, no PK
is required.
2 - I read another post where someone suggested to
remove DefiningQuery element from EF generated EDMX. It is not
working, and I avoid manual changes to automatically generated

Any idea how I can avoid this error, and not define
PK in my

I want to modify one DB which was developed with EF 4.1 (Code
First). I upgraded the project into EF 4.3 and follow this steps: />http://blogs.msdn.com/b/adonet/archive/2012/02/09/ef-4-3-automatic-migrations-walkthrough.aspx


Everything is going well, but when I want to test on current DB
(EF 4.1 Code First), Update-Database raise this error:

Cannot scaffold the next migration because the target database
created with a version of Code First earlier than EF 4.3
and does not
contain the migrations history table. To start
using migrations
against this database, ensure the current

I have build a very very simple database schema as

TicketId (PK)
AreaId (FK) />SeverityId (FK)
AssigneeId (FK)
**Areas**: />AreaId(PK)
SeverityId(PK) />SeverityName

I create the Entity Model and in
the TicketController I am trying to retrieve and Json the data inside
the Tickets table.

I can't seem to find how to eager load multiple child child
collections in EF. So I can do:


.Include(b => b.ChildCollection

peer? collection, The below does not work

.Include(b =>
.Select(cc =>
.Select(cc =>
