What are the main uses of yield(), and how does it differ from join() and interrupt()?
... in a bidimensional array filled with 0s and 1s. An "island" is a group of cells that are adjacent to eachother either vertically or horizontally:
1 0 0 0
1 1 0 0
0 0 0 1
0 0 1 1
0 0 1 1
Here we have two islands of 1s: top-left and bottom-right.
A simple solution is to make a first pass over the...

Functional programming - is immutability expensive? [closed]
...this implementation continually requests memory from the heap for the cons cells of the list and potentially scatters memory all over the place. As a result, this algorithm has a very poor cache locality. I don’t know whether smart allocators in modern functional programming languages can mitigate...
Is Python strongly typed?
...d similar kinds of hackery; on some platforms, double-word floats and cons cells were the same type, and you could just pass one to a function expecting the other and it would "work".
Most languages today aren't quite as weak as C and Lisp were, but many of them are still somewhat leaky. For exampl...
Multithreading: What is the point of more threads than cores?
...ere writing code to perform matrix multiplication, creating one thread per cell in the output matrix might be excessive, whereas one thread per row or per n rows in the output matrix might reduce the overhead cost of creating, pausing, and resuming threads.
This is also why branch prediction is imp...
How does LMAX's disruptor pattern work?
...ntries also means adjacent entries (very likely) locate in adjacent memory cells, and because readers read entries sequentially, this is important to utilize CPU caches.
And lots of efforts to avoid lock, CAS, even memory barrier (e.g. use a non-volatile sequence variable if there's only one writer...
