You can limit the number of rows to be returned by using the maxrows attribute.

Structures in Rust are defined using the struct keyword. The most common form of structure consists of a set of named fields:
struct Foo {
my_bool: bool,
my_num: isize,
my_string: String,
}
The above declares a struct with three fields: my_bool, my_num, and my_string, of the type...
Structures can be made generic over one or more type parameters. These types are given enclosed in <> when referring to the type:
struct Gen<T> {
x: T,
z: isize,
}
// ...
let _: Gen<bool> = Gen{x: true, z: 1};
let _: Gen<isize> = Gen{x: 42, z: 2};
let _: Gen...

In Haskell, all functions are considered curried: that is, all functions in Haskell take just one argument.
Let's take the function div:
div :: Int -> Int -> Int
If we call this function with 6 and 2 we unsurprisingly get 3:
Prelude> div 6 2
3
However, this doesn't quite behave in...
You cam amend the time of a commit using
git commit --amend --date="Thu Jul 28 11:30 2016 -0400"
or even
git commit --amend --date="now"
If you make a commit as the wrong author, you can change it, and then amend
git config user.name "Full Name"
git config user.email "[email protected]"
git commit --amend --reset-author
Android Studio's Live templates can offer quite a few shortcuts for quick logging.
To use Live templates, all you need to do is to start typing the template name, and hit TAB or enter to insert the statement.
Examples:
logi → turns into → android.util.Log.i(TAG, "$METHOD_NAME$: $content$&q...
Caffe can run on multiple cores. One way is to enable multithreading with Caffe to use OpenBLAS instead of the default ATLAS. To do so, you can follow these three steps:
sudo apt-get install -y libopenblas-dev
Before compiling Caffe, edit Makefile.config, replace BLAS := atlas by BLAS := open

Because the WHERE clause is evaluated before GROUP BY, you cannot use WHERE to pare down results of the grouping (typically an aggregate function, such as COUNT(*)). To meet this need, the HAVING clause can be used.
For example, using the following data:
DECLARE @orders TABLE(OrderID INT, Name NVA...
It can be difficult to test functions with poor asymptotic complexity using quickcheck as the random inputs are not usually size bounded. By adding an upper bound on the size of the input we can still test these expensive functions.

We can create a Map from a list of tuples like this:
Map.fromList [("Alex", 31), ("Bob", 22)]
A Map can also be constructed with a single value:
> Map.singleton "Alex" 31
fromList [("Alex",31)]
There is also the empty function.
empty :: Map k a
