i'm working through rxjskoans , i'm seeing recurring pattern of feeding in array of results, subscriber pushes new values onto: var rx = require('rx'), subject = rx.subject var result = []; var s1 = new subject(); s1.subscribe(result.push.bind(result)); s1.onnext('foo'); result; // ['foo'] this impure function; result array mutated subscribe. i've seen small-scale projects on github make stab @ using immutable.js, none actively maintained. im wondering if there's widely-adopted immutable implementation pattern, , if not, why? i wouldn't call pattern, since can pass through stream can pass in immutable data structure: const stream$ = rx.subject.create(); stream$ .map(data => data.set('a', data.get('a') + 1)) .subscribe(data => console.log(data)); stream$.next(immutable.map({ a:1 })); stream$.next(immutable.map({ a:2 })); <script src="https://npmcdn.com/@reactivex/...

i want list of string based in 2 lists lstjobs , lstpraudits. want planid common in both list. here code- list<string> result=reviewmodel.lstjobs.select(x=>x.planid.contains(reviewmodel.lstpraudits.slect(y=>y.planid).tolist())); what doing wrong here. code giving error message. use enumerable.intersect : list<string> result = reviewmodel.lstjobs.select(x=> x.planid) .intersect(reviewmodel.lstpraudits.select(y=> y.planid)) .tolist(); what doing wrong here your approach wrong because x.planid.contains search substrings , passing list method. it's wrong approach anyway because don't want compare substrings.

why command perl -e "print qq/a\n/ =~ /$/" print 1 ? as far know, perl considers $ position both before \n position @ end of whole string in multi-line mode, default (no modifier applied). the match operator returns 1 true value because pattern matched. print outputs value. the $ anchor, specific sort of zero-width assertion. matches condition in pattern consumes no text. since have nothing else in pattern, /$/ matches target string including empty string. return true. the $ end-of-line anchor, documented in perlre . $ allows vestigial newline @ end, both of these can match: "a" =~ /a$/ "a\n" =~ /a$/ without /m regex modifier, end of line end of string. but, modifier can match before newline in string: "a\n" =~ /a$b/m you might behavior if don't see attached particular match operator since people can set default match flags: use re '/m'; # applies in lexical scope over-enthusiastic fans o...

say, want make alarm clock app on android progressive web app. like native alarm app, should notified @ selected time without active web page. at first, considered using push api. of course push message cannot arrived while offline. , push message arrival time cannot accurate enough alarm clock. is possible notified @ time without network connection? what you're describing functionality that's more closely tied periodic background sync , rather push notifications, in push notifications require network connection. periodic background sync has advantage of being network-independent. (periodic background sync proposal right now, , hasn't been implemented in browsers.) but , unfortunately use case, periodic background sync explicitly not designed events need triggered @ precise time, needed make alarm clock useful. that's explicitly called out in proposal: what periodic sync not periodic sync not exact alarm api. scheduling granularity in ...

i'm trying put course notes pdf, , having trouble getting unicode characters display properly. using xelatex latex engine necessary document rendered @ (using default engine results in error due unrecognized characters), however, first unicode character (uppercase delta) displayed properly. for example, when using rmarkdown render() function render following .rmd file: --- output: pdf_document: latex_engine: xelatex --- - works - Δ - doesn't work - ⌘ the resulting pdf shows first unicode character (uppercase delta), , not later 1 (looped square). i know there different character subsets make full utf-8 character encoding, seems perhaps more basic subsets supported. just certain, checked encoding of file using iconv -f utf-8 your_file -o /dev/null [ 1 ], , indeed appear valid utf-8 document. finally, document renders fine html using default options, issue specific pdf output. any ideas how second character render pdf? system information linu...
