Stack vs heap allocation of structs in Go, and how they relate to garbage collection
...variables live on the stack and allocated memory lives on the heap and and Python-style stack-based-programming where the only thing that lives on the stack are references/pointers to objects on the heap.
...
ByteBuffer.allocate() vs. ByteBuffer.allocateDirect()
... Indeed. Like, when need to do IO in Scala/Java and call embedded Python / native libs with large in memory data for algorithmic processing or feed data directly to a GPU in Tensorflow.

Why always ./configure; make; make install; as 3 separate steps?
...t means ./configure, make and make install. But another one can use SCons, Python related setup or something different.
As you see splitting each state makes things much easier for maintaining and deployment, especially for package maintainers and distros.

Is recursion ever faster than looping?
...ou wrote 'language-agnostic', so I'll give some examples.
In Java, C, and Python, recursion is fairly expensive compared to iteration (in general) because it requires the allocation of a new stack frame. In some C compilers, one can use a compiler flag to eliminate this overhead, which transforms ...
What is “callback hell” and how and why does RX solve it?
...ions can vary and include: async, generators, coroutines, and callcc.
In Python we can implement that previous loop example with something along the lines of:
def myLoop():
for i in range(10):
doSomething(i)
yield
myGen = myLoop()
This is not the full code but the idea is t...
Loop through an array in JavaScript
...tional programming technique that's also available in other languages like Python and Haskell.
[1,2,3,4].map( function(item) {
alert(item);
})
The general syntax is:
array.map(func)
In general func would take one parameter, which is an item of the array. But in the case of JavaScript, it ...

What is the difference between native code, machine code and assembly code?
...ow.
Strictly speaking, most dynamically-typed languages — such as Perl, Python, PHP and Ruby — are also managed code. However, they are not commonly described as such, which shows that managed code is actually somewhat of a marketing term for the really big, serious, commercial programming envi...
Why do people use Heroku when AWS is present? What distinguishes Heroku from AWS? [closed]
