LINQ Orderby Descending Query
...
I think this first failed because you are ordering value which is null. If Delivery is a foreign key associated table then you should include this table first, example below:

UnicodeDecodeError, invalid continuation byte
...
In binary, 0xE9 looks like 1110 1001. If you read about UTF-8 on Wikipedia, you’ll see that such a byte must be followed by two of the form 10xx xxxx. So, for example:
>>> b'\xe9\x80\x80'.decode('utf-8')
u'\u9000'
But that’s just the mechanical ca...
AngularJS - wait for multiple resource queries to complete
...
The solution from Ben Lesh is the best but it's not complete. If you need to handle error conditions--and, yes, you do--then you must use the catch method on the promise API like this:

Decorators with parameters?
...
The syntax for decorators with arguments is a bit different - the decorator with arguments should return a function that will take a function and return another function. So it should really return a normal decorator. A bit confusing, right? What I mean is:
