parallel processing - Anonymous Functions Dont Work inside parfor loops in matlab? -

-

i'm not sure if found matlab bug or doing wrong, seems calling anonymous functions inside parfor loop slow down (even slower serial performance)

is correct?

see code:

tic; parfor i=1:6, min(randn(10000000,1)); end; toc tic; i=1:6, min(randn(10000000,1)); end; toc

parallel elapsed time 0.510345 seconds.

serial elapsed time 0.932137 seconds.

same thing except using anon function:

q = @(x) min(randn(10000000,1)); tic; parfor i=1:6, q([]); end; toc   %parelel tic; i=1:6, q([]); end; toc     %serial

parallel elapsed time 4.208346 seconds.

serial elapsed time 0.933594 seconds.

node.js - Why do I get "SOCKS connection failed. Connection not allowed by ruleset" for some .onion sites? -

i'm experimenting node , socks5-https-client . reason, tor hidden service ( .onion ) sites return connection error. for example, connecting duckduckgo ( 3g2upl4pq6kufc4m.onion ) works , returns html. however, connecting pirate bay ( uj3wazyk5u4hnvtk.onion ) or torch ( xmh57jrzrnw6insl.onion ) returns... error: socks connection failed. connection not allowed ruleset. what error mean? how can avoid it? here's code reproduce it: var shttps = require('socks5-https-client'); shttps.get({ hostname: '3g2upl4pq6kufc4m.onion', path: '', sockshost: '127.0.0.1', socksport: 9150, rejectunauthorized: false }, function(res) { res.setencoding('utf8'); res.on('readable', function() { console.log(res.read()); // log response console. }); }); the error seems caused 0x02 value in field 2 of server response. in summary the servers you're failing access don't support ...
