let's have 2 infinite observables can emit values @ moment. combine create observable<processfileevent> . observable<integer> selectedfileid= ... observable<mouseclick> buttonclick = ... observable<processfileevent> `processfileevent` = observable.combinelatest(selectedfileid, buttonclick, (s,b) -> { //create processfileevent here }); the problem want processfileevent emit when buttonclick emits something, not selectedfileid . it's not behavior user expects when file id inputted , kicks off processfileevent . how combine emit when buttonclick emits? use .distinctuntilchanged() on mouseclick object. way you'll events when mouseclick changes. create class contains both fileid , mouseclick : static class filemouseclick { final int fileid; final mouseclick mouseclick; filemouseclick(int fileid, mouseclick mouseclick) { this.fileid = fileid; this.mouseclick = mouseclick; } } then obs...

can use collection splitter split hashmap resulting in messages identified key , containing value in payload? example, have map<string, list<object>> , , process each list differently based on key. if possible, i'm assuming list mapped payload, how key mapped resulting message? message header? you split on entry set of hash map. i.e use following split expression #[maymap.entryset()] please see javadoc method understand how key , value each entry.

i need return validation check (boolean) if number has no more 6 number of digits , no more 2 decimal places. for example: 1 = valid 10 = valid 111111 = valid 111111.11 = valid 1111111.11 = invalid 1.111 = invalid looking through stack overflow can find answers input automatically rounded (not want) or decimal places have equal 2 decimal places (not @ 2). obviously, need function valid(n) { return no_more_than_six_digits(n) && no_more_than_two_decimal_places(n); } so how define these functions? function no_more_than_six_digits (n) { return n < 1e7; } function no_more_than_two_decimal_places(n) { return math.floor(n * 100) === n * 100; }

i have ekevent occurs every 4 hours, , want create single recurring event. unfortunately available frequencies in ekrecurrencerule class daily, weekly, monthly, , yearly. how can set hourly frequency ekrecurrencerule object ? unfortunately there no way make hourly events using ekrecurrencerule objects, can still write method same. func createhourlyrecurringevent(eventtitle: string, startdate: nsdate, enddate: nsdate, endreccurencedate: nsdate, allday : bool, recurrencesecondsinterval: double, alarms: [ekalarm]? , traveltime: int?) { var eventstartdate = startdate var eventenddate = enddate while eventstartdate.earlierdate(endreccurencedate) != endreccurencedate { let event = ekevent(eventstore: self.eventstore) event.title = eventtitle event.startdate = eventstartdate event.enddate = eventenddate event.allday = allday event.alarms = alarms event.calendar = eventstore.defaultcalendarf...

i'm new angular world , have been using angular-fullstack generator + yeoman build out project. i'm using sublime (not webstorm) , have been trying figure out how set project can debug mocha tests terminal, hitting wall. here's default things.spec.js that's generated 'yo angular-fullstack' debugger statement added in. var should = require('should'); var app = require('../../app'); var request = require('supertest'); describe('get /api/things', function() { it('should respond json array', function(done) { request(app) .get('/api/things') .expect(200) .expect('content-type', /json/) .end(function(err, res) { debugger; if (err) return done(err); res.body.should.be.instanceof(array); done(); }); }); }); by combining advice grunt-mocha-test documentation , so answer , i've upd...

i have tcpdumps (.pcap) files of captured packets millions of packets. need group network packets tcp streams. example: let consider following packets no => source_ip, destination_ip,source_port,destination_port 1 => ip1, ip2, s1, s2 2 => ip1, ip3, s3, s4 3 => ip2,ip1, s2, s1 4 => ip3,ip1, s4,s3 now in above example of 4 packets, packets 1,3 , 2,4 packets of same stream. i.e need resolve following packets [[1,3],[2,4]]. my approach: since (ip1, ip2, s1, s2) , (ip2, ip1, s2, s1) indicates same stream decided hash both of them , name forward_hash , reverse hash denote packets of same stream flowing in opposite directions. i use index array keep track of packets during replacing , sorting. after final sorting, starting , ending of same hashes extracted , used against index array packet indices represent stream keys forward_hash of each packets, count number of packets, packet_ids id of each packet corresponding each of hash thrust::device_vect...
