seems simple user's timeline tweets , exclude replies , retweets, or without count&page params in user_timeline.json looks impossible first (non reply, non retweet) tweet of user tweet not in first place in api response. for example @gmail has last tweet 30.8.2017, first 7 pages each having max 200 results full of replies , retweets, need filtered out. when using paging params, not, doc says - these unwanted records filtered after applying paging params: "using exclude_replies count parameter mean receive up-to count tweets — because count parameter retrieves many tweets before filtering out retweets , replies." so there other way (besides stream api, , search limited 7 days given @gmail tweet won't returned wel) iterating through result pages until first (non reply, non retweet) tweet met?

so ran weird.. i'm using 7-1 pattern css needs. unfamiliar can read here: https://sass-guidelin.es/ i have _variables.scss file have css variables declared. question can access these variables in other .scss files without using import statement in particular file. can explain why? edit: guess have main.scss file scss watching importing other files. time css attempting transpiled variables available in other files? i'm gonna assume you've got 1 master import file, like: @import 'variables' @import 'base' @import 'some_component' @import 'some_other_component' the reason variables available other stylesheets imports cascade. so, import variables , imported after in same scope variables (as they've been imported). this can blessing , curse, variables define outside of block scope in of other stylesheets become globally available stylesheets imported after one. because of this, it's considered best practice impo

i trying understand how manage redux state in react-native app. in particular, trying work out happens when app minimized or device turned off. with knowledge can work out best how persist state, , prepare illegal states may arise redux state being reset. is fair assumption make if redux state reset, entire app restart (and therefore initialization of redux store called again?). is fair assumption make if redux state reset, entire app restart this assumption not true, inverse is. redux state can reset during runtime if there code via reset action or otherwise. however if app shut down, , code re-runs loaded default redux state. asyncstorage (in native) / localstorage web, used in conjunction redux in order persist state across app crashes / browser sessions. you can set asyncstorage strategy redux-persist middleware (or write own)

"completes" means task coroutine has finished. in case want use async sleep can computer other tasks while sleep-task running, makes

i have big database in firebase. in opinion it's wrong structured. trying snapshot of reference, takes time processing results. however, don't need retrieve data. don't need deepers items don't know how can superficials. so structure this: clients { 1234 { name: 'paul', last_name: 'mcartney', city: 'liverpool', account_movements: { item1: { ... } } } 1234 { ... } 1236 { ... } } let's supose need clientes data except account_movements . because talking big database suggest restructure database little bit. frank says, when trying read node, entire node. means every time add listener specific reference, downloading entire information of object. note, there no way in can download subset of properties of each node , that's why need denormalize database. because important rule in firebase have database flatten possible, suggest account_movement

i've been developing javascript few years , don't understand fuss promises @ all. it seems change: api(function(result){ api2(function(result2){ api3(function(result3){ // work }); }); }); which use library async anyway, like: api().then(function(result){ api2().then(function(result2){ api3().then(function(result3){ // work }); }); }); which more code , less readable. didn't gain here, it's not magically 'flat' either. not mention having convert things promises. so, what's big fuss promises here? promises not callbacks. promise represents future result of asynchronous operation . of course, writing them way do, little benefit. if write them way meant used, can write asynchronous code in way resembles synchronous code , more easy follow: api().then(function(result){ return api2(); }).then(function(result2){ return api3(); }).then(function(resu

i have data frame (called coors) contains vector of x coordinates , vector of y coordinates. i have data frame (called pickedpoint) contains specified (x,y) pairs of interest. the goal associate each coors point nearest pickedpoint. want use euclidean norm (l-2) . if @ possible please tidyverse methods. coor = data.frame(row = rep(1:96, each = 72), col = rep(1:72, times = 96)) pickedpoint = data.frame(pprow = sample(96,10), ppcol = sample(72,10)) there thread similar posted in python: how find closest (x, y) position (x,y) position in list? i have included benchmark answers far: microbenchmark(cpak(), latemail(),jul(), times=10l) unit: milliseconds expr min lq mean median uq max neval cpak() 37.83691 38.60585 43.66030 39.86094 44.9592 62.784 10 latemail() 4275.10 4536.783 4674.966 4712.938 4855.860 5045.069 10 jul() 37.38809 39.87625

i not able understand, why prefer mailbox on queue inter process communication (eg: communication between driver , scoreboard)? a mailbox built-in class around queue uses semaphores control access ends of queue. mailbox has fifo element ordering whereas can access head, tail, or middle elements of queue. you typically use mailbox when there multiple threads reading , writing data , need atomic test-and-set operation of semaphore know when mailbox full or empty. if have 1 process reading , writing queue, there no need use mailbox. if there more 1 thread, mailbox convenient class use. in uvm, use tlm fifo wrapper around mailbox. tlm connections provide isolating interface don't have know on other side of port. see https://verificationacademy.com/sessions/how-tlm-works

this question has answer here: what's simplest way print java array? 23 answers public static void main(string[] args) { list<integer> numbers1 = arrays.aslist(1,2,3); list<integer> numbers2 = arrays.aslist(3,4); list<int[]> intpairs = numbers1.stream() .flatmap(i -> numbers2.stream() .filter(j -> (i+j)%3 == 0) .map(j -> new int[]{i,j})) .collect(collectors.tolist()); intpairs.stream().foreach(system.out::println); } for above code, getting output as: [i@214c265e [i@448139f0 but expectation [(2, 4), (3, 3)] . could please guide me achieve this? you can change mapping part list instead of using int[] : .... .map(j -> arrays.aslist(i,j))) .... and output following: [2, 4] [3, 3] here complete example: public static voi

im totally new programming, picked c manual learn on own. dont want use array im trying practice getchar(). want able output error message if user enters other digit or alphabet. trying practice c library function isalpha() , isdigit(). wrote far, output not quite right. input 1 : "hello" expected output : "valid output" input 2 : "hello5" expected output : "valid output" input 3 : "hello!" expected output : "invalid output" but program returns "valid input" 3 inputs above please newbie try learn. appreciate it. #include <stdio.h> #include <ctype.h> int main () { char ch; int len; int valid; printf("enter word: "); for(length = 0; (ch = getchar()) != '\n'; len++) { if(isalpha(ch) || isdigit(ch)) { valid = 1; } else { valid = 0; } } printf("

i still puzzled basic question not yet find answer: if create in c# edm (using database first approach) - there best practices in number of tables choose? select whole db/all tables - flexible possible later? i.e. you'd work off 1 "complete model" in application. or try restrict/limit tables absolutely need in model? or generate multiple models different tables? are there (serious) performance worries, if have tables in model, later not actively addressing? thank input in advance. it depends on specific situation, consider problem, whether need data or not?? working in web environment or using local application? if connect on web better grab data once, if tables heavy , not need of them, why should that?? load need,

all, have question on networking between 2 nics on same machine under linux. suppose both nics different ip addresses , can communicate outsides. when sending data ip address of nic 1 of nic 2, data sent outside network , forwarded nic2, or sent receiver directly inside kernel, without going outsides. opinion if 2 ip addresses belong different subnets, data sent router first. if 2 ips off same subnet? bother send data first to, example, switch, , looped nic2, or kernel recognize destination on same node , transfers receiver without going through physical wire? thank much! i don't think it's case 2 nics on same subnet can "see" each other @ all, unless routing table set can. i have 2 network adapters in test box, addresses in same subnet. if try use "ping -i {interface}" ip number, no response if 1 interface other. is, fails if specify 1 interface, , ip number other interface. way can packets 1 interface other use ips take traf
