python - Is there a difference between TCP and UNIX socket? -


for tcp socket, many client connect , send data , close. unix socket, if client close socket, server side close. it?

but in opinion, tcp has stop state....

this python unix socket code:

sock_file = "%s_%d.sock" % (sock_name, port) sock = socket.socket(socket.af_unix, socket.sock_stream) sock.bind(sock_file) sock.listen(1)

taken serverfault (what's difference between unix socket , tcp/ip socket):

a unix socket inter-process communication mechanism allows bidirectional data exchange between processes running on same machine.

ip sockets (especially tcp/ip sockets) mechanism allowing communication between processes on network. in cases, can use tcp/ip sockets talk processes running on same computer (by using loopback interface).

unix domain sockets know they’re executing on same system, can avoid checks , operations (like routing); makes them faster , lighter ip sockets. if plan communicate processes on same host, better option ip sockets.

unix domain sockets subject file system permissions, while tcp sockets can controlled on packet filter level.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
