javascript - Is there a way to detect changes within the same route? -

with iron router, have following route set up: router.route('/:cat', { name: "goods", waiton: function() { session.setdefault('limit', 20) var limit = session.get('limit') || 20 meteor.subscribe('goods', this.params.cat, limit) } }) the idea user can press bunch of buttons change cat (egory), filtering out data remaining on same route. classic stuff. right sets default limit of 20 , user scrolls down, increased. if clicks button change category, doesn't make sense instantly load 100 new items, set limit 20 again. problem is, can't think of way that. removing setdefault use session.set won't work. can think of right logging cat in session , use check if category has been changed, hoping there better way. how using template manage state (instead of sessions , route. for example, using reactivate variable (reactive-var package), , passing category through route template. ...

erlang - Why no need to remember the socket handle in handle_info? -

i confused chapter 4 example of "erlang , otp in action". https://github.com/erlware/erlang-and-otp-in-action-source/blob/master/chapter_04/tcp_rpc/src/tr_server.erl#l92 handle_info(timeout, #state{lsock = lsock} = state) -> {ok, _sock} = gen_tcp:accept(lsock), {noreply, state}. the book said: you don’t need remember socket handle returned accept, because it’s included in each data package. what mean exactly? what's "data package"? why socket handle name prefixed underscore? why no need save somewhere in case of gc? happens behind scene? gen_server behavior seems difficult follow. explain in simple , clear way? when establish connection in erlang tcp sockets, can make socket active or not active. if socket active, every time receive data client, send erlang message format {tcp, socket, data} , tcp tuple id, socket variable have information regarding socket, on local port listening, on interface, , port/ip of peer sendi...
