Parallelism in Haskell can be expressed using the Eval Monad from Control.Parallel.Strategies, using the rpar and rseq functions (among others). f1 :: [Int] f1 = [1..100000000] f2 :: [Int] f2 = [1..200000000] main = runEval $ do a <- rpar (f1) -- this'll take a while... b <- rpa...

rpar :: Strategy a executes the given strategy (recall: type Strategy a = a -> Eval a) in parallel: import Control.Concurrent import Control.DeepSeq import Control.Parallel.Strategies import Data.List.Ordered main = loop where loop = do putStrLn "Enter a number" ...

We can use rseq :: Strategy a to force an argument to Weak Head Normal Form: f1 :: [Int] f1 = [1..100000000] f2 :: [Int] f2 = [1..200000000] main = runEval $ do a <- rpar (f1) -- this'll take a while... b <- rpar (f2) -- this'll take a while and then some... rseq a return ...

[UIView animateWithDuration:1.0 animations:^{ someView.alpha = 0; otherView.alpha = 1; } completion:^(BOOL finished) { [someView removeFromSuperview]; }]; The carat “^” character defines a block. For example, ^{ … } is a block. More specifically, it is a blo...

Big Data, in its most basic form, can be described as the umbrella term metricized by different aspects of data.

In Rust, there are two main methods to indicate something has gone wrong in a program: A function returning a (potentially custom-defined) Err(E), from the Result<T, E> type and a panic!. Panicking is not an alternative for exceptions, which are commonly found in other languages. In Rust, a p...

Creating arrays explicitly using ArrayNew() Declare an array with the ArrayNew function. Specify the number of dimensions as an argument. ArrayNew(dimension) creates an array of 1–3 dimensions. ColdFusion arrays expand dynamically as data is added. ArrayNew() returns an array. History Intr...

To view all elements in the index change the print options that “sparsifies” the display of the MultiIndex. pd.set_option('display.multi_sparse', False) df.groupby(['A','B']).mean() # Output: # C # A B # a 1 107 # a 2 102 # a 3 115 # b 5 92 # b 8 98 # c 2 87 # c 4 104 #...

The header ctype.h is a part of the standard C library. It provides functions for classifying and converting characters. All of these functions take one parameter, an int that must be either EOF or representable as an unsigned char. The names of the classifying functions are prefixed with 'is'. Ea...
