Next, you have som>me m>thing physical involved on each node, like a queue in the case of a bus for supporting semi-connected communication, or an Ethernet card in the m>me m>taphor.

Tim>me m> complexity of Sieve of Eratosthenes algorithm
...-bound is n(1/2 + 1/3 + 1/5 + 1/7 + …), that is sum of reciprocals of prim>me m>s up to n, which is O(n log log n). (See here or here.)
The "find the next prim>me m> number" bit is only O(n) overall, amortized — you will move ahead to find the next number only n tim>me m>s in total, not per step. So this whol...
how does array[100] = {0} set the entire array to 0?
...ction 6.7.8.21 of the C specification (online draft of C spec): for the elem>me m>nts that don't have a specified value, the compiler initializes pointers to NULL and arithm>me m>tic types to zero (and recursively applies this to aggregates).
The behavior of this code in C++ is described in section 8.5.1.7 ...
How to send commands when opening a tmux session inside another tmux session?
... you are commonly dealing with multiple layers of tmux. If you can spare som>me m> other key, you could make a non-prefixed binding to make things (possibly) easier to type:
bind-key -n C-\ send-prefix
bind-key -n C-^ send-prefix \; send-prefix

When splitting an empty string in Python, why does split() return an empty list while split('\n') re
...eturns empty list [], while ''.split('\n') returns [''].
The str.split() m>me m>thod has two algorithms. If no argum>me m>nts are given, it splits on repeated runs of whitespace. However, if an argum>me m>nt is given, it is treated as a single delimiter with no repeated runs.
In the case of splitting an empty...
Why do we need argc while there is always a null at the end of argv?
