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.

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...
Why does this loop produce “warning: iteration 3u invokes undefined behavior” and output more than 4
...e have an infinite loop.
He explains this is very similar to the infamous Linux kernel null pointer check removal where in seeing this code:
struct foo *s = ...;
int x = s->f;
if (!s) return ERROR;
gcc inferred that since s was deferenced in s->f; and since dereferencing a null pointer is...
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 ...
Why should I use core.autocrlf=true in Git?
...r "strong recommendation" will cause problems. Try running a bash, perl or python script with the shebang ending with \r\n and you'll see.
