network programming - Basic Distributed Counter using Java Sockets -

-
i have java processes(socket programs) running on different servers, on same network , on different networks. these processes have job maintain global counter . client can connect of these processes , issue command increase , decrease or get counter value. global counter should consistent( network partition can occur , can recover it). the solution have thought of far maintain count of increments , decrements on each node nodes. when increment command issued on node, increments own local copy of counts of increments , broadcasts increment , decrement count. nodes receive broadcast take max of received counts , local copy of sender's counts , stores result latest count. when get command issued on node gives difference of sums of increments , decrements. assume take care of cases broadcasts received out of order , other unreliabilities. don't want use persistence layer. is there better way implement this? protocol should use broadcast counts? gossip on udp work?

Python JQUERY like syntax to mimic Unix Shell Pipelines -

i not sure if has been asked before, wondering how can implement "set oriented" syntax in python mimic unix shell pipelines. in particular, how use "plain python functions" can produce, modify, or consume stream of records, , can glued using "." operator. a straightforward example assuming python functions unix programs: in unix can do: ls | egrep '^a' | wc -l to count files in current directory start 'a'. how about: unixtools import * ls().egrep('^a').wc(countlines=true) and implementation of ls generator: @pipeline def ls(): file in glob.glob("*"): yield file i have omitted obvious glue code, make possible connect ls other "commands" of pipeline. @pipeline attempt use decorators convert plain python function member of pipeline protocol. i realise can done using traditional syntax of python, less readable forcing write in reverse, , more error prone
