VBA is compiled in run-time, which has a huge negative impact on it's performance, everything built-in will be faster, try to use them. As an example I'm comparing SUM and COUNTIF functions, but you can use if for anything you can solve with WorkSheetFunctions. A first attempt for those would be t...

This example shows how to mock out a function call that is irrelevant to our unit test, and then use the defer statement to re-assign the mocked function call back to its original function. var validate = validateDTD // ParseXML parses b for XML elements and values, and returns them as a map of ...

So here, I have removed the for loops, and made a timeout by adding a second case to the select that returns after 3 seconds.

Subroutine arguments in Perl are passed by reference, unless they are in the signature. This means that the members of the @_ array inside the sub are just aliases to the actual arguments. In the following example, $text in the main program is left modified after the subroutine call because $_[0] in...

It's both designer and developer friendly by sticking to PHP's principles and adding functionality useful for templating environments. The key-features are... ...

Lazy evaluation means Haskell will evaluate only list items whose values are needed. The basic recursive definition is: f (0) <- 0 f (1) <- 1 f (n) <- f (n-1) + f (n-2) If evaluated directly, it will be very slow. But, imagine we have a list that records all the results, fibs ...

The R-Logo is a multilayer raster file (red, green, blue) library(raster) r <- stack("C:/Program Files/R/R-3.2.3/doc/html/logo.jpg") plot(r) The individual layers of the RasterStack object can be adressed by [[. plot(r[[1]])

Selection sort selects the minimum element, repeatedly, until the list is empty. import Data.List (minimum, delete) ssort :: Ord t => [t] -> [t] ssort [] = [] ssort xs = let { x = minimum xs } in x : ssort (delete x xs)

Consider the case of creating a nested list structure by multiplying: li = [[]] * 3 print(li) # Out: [[], [], []] At first glance we would think we have a list of containing 3 different nested lists. Let's try to append 1 to the first one: li[0].append(1) print(li) # Out: [[1], [1], [1]] ...
