Lambda expressions are similar to anonymous functions in other languages.
Lambda expressions are open formulas which also specify variables which are to be bound. Evaluation (finding the value of a function call) is then achieved by substituting the bound variables in the lambda expression's body, ...
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
[TimeStamp] attribute can be applied to only one byte array property in a given Entity class. Entity Framework will create a non-nullable timestamp column in the database table for that property. Entity Framework will automatically use this TimeStamp column in concurrency check.

Function scope is the special scope for labels. This is due to their unusual property. A label is visible through the entire function it is defined and one can jump (using instruction gotolabel) to it from any point in the same function. While not useful, the following example illustrate the point:

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 is sometimes required for a process to concurrently write and read the same "data".
The ReadWriteLock interface, and its ReentrantReadWriteLock implementation allows for an access pattern that can be described as follow :
There can be any number of concurrent readers of the data. If...

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.
