Is there a software-engineering methodology for functional programming? [closed]
... captured as higher-order functions. For example, the Visitor pattern is known in the functional world as a "fold" (or if you are a pointy-headed theorist, a "catamorphism"). In functional languages, data types are mostly trees or tuples, and every tree type has a natural catamorphism associated w...
Color in git-log
... Shahar (upvoted), git 1.8.3 offers one more option:
git log –format now sports a %C(auto) token that tells Git to use color when resolving %d (decoration), %h (short commit object name), etc. for terminal output.
This Atlassian blog post comments that this feature is part of several others ...
Is it safe to ignore the possibility of SHA collisions in practice?
... crashes on Earth within the next second, obliterating civilization-as-we-know-it, and killing off a few billion people? It can be argued that any unlucky event with a probability lower than that is not actually very important.
If we have a "perfect" hash function with output size n, and we have p ...
How to use Git properly with Xcode?
...Cocoa PList file, which is older, and defined a lot earlier than JSON, and now deprecated by Apple. (but they are still using it in some places) The mention about the file in the book is completely wrong. I removed down vote because you mentioned it explicitly.

Memory footprint of Haskell data types
...ords, and a Due takes 3.
The Int type is defined as
data Int = I# Int#
now, Int# takes one word, so Int takes 2 in total. Most unboxed types take one word, the exceptions being Int64#, Word64#, and Double# (on a 32-bit machine) which take 2. GHC actually has a cache of small values of type Int...
Async/await vs BackgroundWorker
...an use async/await with, BackgroundWorker is creating the thread for you.
Now, you could use TPL instead:
var synchronizationContext = TaskScheduler.FromCurrentSynchronizationContext();
Task.Factory.StartNew(() =>

int i = 0;

Why use Gradle instead of Ant or Maven? [closed]
...ations of Ant and Maven.
In my experience Ant is often write-only (yes I know it is possible to write beautifully modular, elegant builds, but the fact is most people don't). For any non-trivial projects it becomes mind-bending, and takes great care to ensure that complex builds are truly portable....
Is there a difference between copy initialization and direct initialization?
...hy does it output that result?
Direct initialization
It first doesn't know anything about conversion. It will just try to call a constructor. In this case, the following constructor is available and is an exact match:
B(A const&)
There is no conversion, much less a user defined conversio...
Can I pass an array as arguments to a method with variable arguments in Java?
...rraycopy(arr, 0, arr, 1, N);
arr[0] = firstElement;
return arr;
}
Now you can do the following:
String[] myArgs = { "A", "B", "C" };
System.out.println(ezFormat(append(myArgs, "Z")));
// prints "[ A ][ B ][ C ][ Z ]"
System.out.println(ezFormat(prepend(myArgs, "Z")));
