i trying connect multiple arduino mega boards via serial pins allow communication between boards. want able connect arbitrary amount of arduinos daisy-chaning them , want 1 board master, taking control on actions of other boards. master should determined dynamically boards. aware daisy chaining method introduces delays communication due forwarding of packets, far planning on connection 4 boards @ most. in future might increase maybe 10 boards. boards have separate power source, since connected other hardware has own power source. my idea connect boards in such way, master determined wireing of boards. thought having "serial" port 'to-master' serial port , "serial1" port "to-child" serial port. boards send hello messages on "to-master" serial port , master replies if received such message on "to-child" serial port. if no answer received after seconds, board determines master. i wired boards connecting ground pins, , wirin...

according issue https://github.com/rails/sass-rails/pull/192 sass-rails hasn't support sass 3.3 yet. but seems sass-rails-source-maps has been depending on sass 3.3 since beginning. there way use gem sass-rails ? according readme sass-rails-source-maps , chrome dropped support of source maps files sass older version 3.3. does mean there no way of using sass source maps chrome devtools now? there great new drop in replacement sass-rails, not faster, has option use inline source-maps. just add gemfile #gem 'sass-rails', '~> 5.0' gem 'sassc-rails' and add configuration # config/environments/development.rb config.sass.inline_source_maps = true don't forget restart server, should see working in inspector: you can find repo here: https://github.com/sass/sassc-rails

is possible instruct redis accumulate set of operations , issue "publish all" command publish entire set of operations ( in linear order ) ? so you'd somehow set marker ( startpublish ? ) , cache accumulate operations ( hdel hset ) received point on. finally you'd issue command ( publishall ? ) , redis broadcast commands in linear order received. important note: need perform set-operations programmatically in node.js, via redis sentinel client ( package redis-sentinel-client ). you can queue multiple commands redis using multi , exec redis command. so end this: redis > multi redis > set foo bar redis > set alpha beta redis > exec what array, in same order execute commands. result set @ index 0 of resulting array contain error and/or result of command set foo bar . example multi command can found here: http://redis.io/commands/multi

i reading book douglas crockford, , uses construct of function.method('inherits', function(parent){ this.prototype=new parent(); return this; }); if leave alone meaning of it, can't around syntax. try run in chrome, , uncaught typeerror: undefined not function test3.html:18 (anonymous function) as happens if try ( jsfiddle ) function.method("test", function () { return "test"; }); there seems post says line working, can't make work. why can be? the reason line working in the post refer to because function.prototype has been extended method: function.prototype.method = function (name, func) { this.prototype[name] = func; return this; }; if run above code , run code have, work - or can change .method .prototype[name_here] = , work same. a note on best practices if going extend prototypes in day , age better use object.defineproperty ensure method not enumerable.

i have same graph represented @ 2 different times, g.t0 , g.t1 . g.t1 differs g.t0 having 1 additional edge maintains same vertices. i want compare communities in g.t0 , g.t1 , is, test whether vertices moved different community t0 t1. tried following library(igraph) m <- matrix(c(0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0),nrow=4,ncol=4) g.t0 <- graph.adjacency(m) memb.t0 <- membership(edge.betweenness.community(g.t0)) v(g.t0) # vertex sequence: # [1] 1 2 3 4 memb.t0 # [1] 1 2 2 3 g.t1 <- add.edges(g.t0,c(1,2)) memb.t1 <- membership(edge.betweenness.community(g.t1)) v(g.t1) # vertex sequence: # [1] 1 2 3 4 memb.t1 # [1] 1 1 1 2 but of course problem indexing of communities start 1. in example seems vertices have moved different community, intuitive reading vertex 1 changed community, moving 2 , 3. how approach problem of counting number of vertices changed communities t0 t1? actually not easy question. in general need match communities in 2 graphs, ...
