i want visualize embedding r^2 r^2. have overlaid scatter plots of original data , transformed data. want join dots stars corresponding same color line can see how each point gets transformed. idea how in r. reproducible example of overlaid scatter plot given below. set.seed(18) m<-cbind(a=runif(10),b=runif(10)) n<-cbind(d=rnorm(10),e=rnorm(10)) plot(n[,1],n[,2],col=rainbow(10),pch=20,xlab="x",ylab="y") points(m[,1],m[,2],col=rainbow(10), pch=8) one way segments segments(n[,1], n[,2], m[,1], m[,2], col = rainbow(10))

i new programmer in prolog , tried program says: make predicate penta(x) , x list , returns true when in x there 5 consecutive elements : first element sum between first , second. third element difference between 5th , 4th example: x = [ ... 5, 7, 12, 18, 30, ... ] . so did this: penta(x) :- \+length(x,0), //here verify if lists contains less 5 elements gives false. \+length(x,1), \+length(x,2), \+length(x,3), \+length(x,4), (a, b, c, d, e | x), c + b, c d - e, penta(x). this not compile doesn't work yet. tell me what's wrong if like. thank much. in prolog, write predicates not functions . predicate defines rule succeed or fail on sets of instantiated variables. want predicate, penta(x) succeeds if x list contains 5 consecutive elements meeting criteria. start top. either 5 consecutive elements meet criteria @ head of list, or later in list. % succeed if first 5 elements meets criteria penta([a, b, c, d, e |_]) :- ... % goes here succeed? %

i need compare 2 dates/time stamps , see if within 10 minutes of each other in sql. if within 10 minutes of each other, not want data output in. if outside of 10 minutes, output data. example: if event 1 occurs on saturday 9/10/2017 10:00:00, , event 2 occurs on saturday 9/10/2017 10:00:09, not want data queried. if event 1 occurs on saturday 9/10/2017 10:00:00, , event 2 occurs on saturday 9/10/2017 10:00:11, want data queried.

i trying make client-server connection server containing 1 service 1 characteristic contains 1 descriptor. i've made service, characteristic , descriptor have same uuid , when try write on descriptor/characteristic (in android app) pop-up appears tells me , bluetooth has shut down becouse of problem (not known). there condition uuid's have distinct ? the "uu" of uuid means "universally unique". uuid describing type of data, though, can have 2 characteristics same uuid if both providing same sort of data. (ex 2 thermometers) think descriptors supposed have uuid's dictated standard (so know they're descriptors). so, service, characteristic, , descriptor should have different uuid's.

when use facebook graph api explorer , send post request page_id/subscribed_apps?access_token=access_token all ok, page appears in subscribed pages webhook. but when use fb node.js api , send request like: fb.api( /${fbselectedpage}/subscribed_apps, 'post', {"access_token": ${selectedpagetoken}}, function(response) { console.log(response); } ); page not appear in subscribed pages webhook section. same postman. works graph api explorer. does know solution? p.s. real subscribe many pages 1 app , webhook events them?

i develop chrome extension compatible firefox/edge/opera. the extension rely on rest api accessible on web. during web development, prefer pointing development endpoint not affect production tenant , affect development instance , database. my question quite simple, make similar pseudo-code: if (extension.downloaded_from_store == true) endpoint = "https://api-dev.example.com" else // extension has been installed local directory endpoint = "https://api-prod.example.com" do have idea how such thing (preferably background.js page) ? if solution can compatible browsers, perfect ! most google chrome extensions on store have permanent extension id. if packaged extension uses same extension id each update can hardcode id , check inside first if. i recommend reading more packaging chrome extensions here. specifically this part.

is possible use placement-new change type of polymorphic object? if not, in standard prohibits it? consider code: #include <new> struct animal { animal(); virtual ~animal(); virtual void breathe(); void kill(); void *data; }; struct dead: animal { void breathe() override; }; void animal::kill() { this->~animal(); new(this) dead; } is calling "kill" ever legal? update: comments not address (il)legality according standard of programming technique shown here of changing type of object explicit call destructor , applying placement-new new object compatible. because there interest in why this, can mention use case led me question, although not relevant question asking. imagine have polymorphic type hierarchy several virtual methods. during lifetime of object, things happen can modeled in code object changing type. there many legal ways program this, example, keeping object pointer, smart or not, , swapping in copy of o

i have been reading blockchain , ethereum, cannot seem head around couple of concepts. first, in blockchain newly created transaction stored ? if blockchain has been on going time, , lets on block x right now. if deploy contract today, , gets executed, transaction details reside on every block after block x or on block x + 1 ? , transaction details details on block, or block contain every transaction happened within time period ? again, of prior blocks transactions written subsequent blocks ? happens if more 1 transaction gets executed same contract, written 2 different blocks or within same block ? second, when designing contract have seen restricted 2 parties enter it, , other people use contract new instance of contract has created, understanding correct ? or should 1 contract designed in way uses , 1 instance of ever created ? where in blockchain newly created transaction stored ? in blocks each node stores. will transaction details reside on every block

none of value members of tuple2 class appear when search them. examples: _2 , invert , swap are classes intentionally left out when doing scaladoc search? browser playing tricks on me? i guess intentional; tuple2 inherits _2 product2 (which show in search results), perhaps designers of search interface thought overly redundant search output include separate result every subtype. you can click on product2 , "known subclasses" find out tuple2 inherits method.

i have binary file can deserialized text representation along supporting image files. can use smudge , clean conversion 1 file many, , again? eg: the binary file: demo.bin would deserialize to: demo.txt (important able diffs on file) demo.picture1.bmp demo.picture2.gif the short answer "no". longer answer more complicated: sure, can write such files work-tree want. cannot make them wind in index , though, definition untracked files. try overwrite existing index files fraught peril. (both old style filter-driver , new-style filter-as-process expected / assumed (by git) work on 1 specified path @ time. using process method, perhaps delay touching index until filter terminated, before git assumes done whatever doing—whether requires smudging or cleaning.)

while i'm debugging, value of ex comes 0. i can't modify or read listbox values on different form. have 2 forms here. how can resolve this? form1 eski = new form1(); form2 yeni = new form2(); listbox array = new listbox(); int ex = eski.listbox5.items.count; (int ix = 0; ix <= ex; ix++) { array.items.add(eski.listbox5.items[ix]); } the problem on code one: form1 eski = new form1(); you initializing new form , code not call opened form1 running on application. you need replace , instead: var eski = application.openforms.oftype<form1>().singleordefault(); with that, can access controls want.
