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...
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.

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

After adding PrimeFaces to your JSF project, you can start using it in your pages using the namespace:
xmlns:p="http://primefaces.org/ui"
or, for PrimeFaces Mobile:
xmlns:p="http://primefaces.org/mobile"
This example should render a spinner:
<html xmlns="http...
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...

Function-like macros are similar to inline functions, these are useful in some cases, such as temporary debug log:
#ifdef DEBUG
# define LOGFILENAME "/tmp/logfile.log"
# define LOG(str) do { \
FILE *fp = fopen(LOGFILENAME, "a"); \

This attribute is applied to the class property. You can use ConcurrencyCheck attribute when you want to use existing columns for concurrency check and not a separate timestamp column for concurrency.

Basically, parfor is recommended in two cases: lots of iterations in your loop (i.e., like 1e10), or if each iteration takes a very long time (e.g., eig(magic(1e4))). In the second case you might want to consider using spmd . The reason parfor is slower than a for loop for short ranges or fast itera...
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
