i trying run sample code book build watchos: develop , design. following segment of code returns 2 errors: @ibaction func buttontapped(){ if animating { spinnerimage.stopanimating() animating = false animatewithduration(0.2, animations: updatebuttontostopped()) } else { spinnerimage.startanimating() animating = true animatewithduration(0.2, animations: updatebuttontogoing()) } } both errors occur in calls animatewithduration() , indicate there type conflict. ideas of how can fix this? in hurry? instead of calling animatewithduration so: animatewithduration(0.2, animations: updatebuttontostopped()) you'd give updatebuttontostopped function parameter so: animatewithduration(0.2, animations: updatebuttontostopped) notice () after updatebuttontostopped gone. and same goes updatebuttontogoing of course :) why? if @ documentation animatewithduration

i'm working on inherited codebase uses posix message queues pass data between processes. because of nature of mq , messages have passed in form of bytes , numbytes passed along when messages reconstructed, there's lot of ugly static_cast<pvoid> -ing. question is there interprocess message passing interface in linux maintains datatype of content? or there better way of doing this?

i'm trying create hypermedia api in rails. i'd serialize payloads active_model_serializers using json_api adapter. doesn't seem trivial serialize links conditionaly. it's kind of blog application users can follow other users. when serialize user resource, usera, want have link rel :follow if current_user not following usera , link rel :unfollow if current_user following usera. seems extremely trivial use case when creating hypermedia api. know if there's way of doing active_model_serializers? i wrote (and include in serializers): def self.link(rel, &block) serializer = self super user = scope next unless serializer.can?(user, rel, @object) instance_eval(&block) end end # , in serializer (just usual): link :self api_user_path(object.id) end it work. don't feel right. , wouldn't surprised if future changes active_model_serializers screw things me. if else looking solution here did.

is there way prevent changes (i.e., lock or hide) calculated columns or scripts in spotfire file (.dxp). we trying deploy template / file built in spotfire , our team use , prevent accidental changes while continue work on updates etc... any appreciated! there couple of ways can go this. scripting can remove scripting licenses users of dxp. wouldn't prevent calculated column changes. best method, in opinion, duplication , versioning. deploy live template public folder , keep backup in folder have access. then, edit copy of template version control number template2_2.dxp. when ready deploy it, overwrite live version. have of live version, need backup newest one. it's basic easy method , ensures don't leave room mistakes or on limit users removing licenses.

i'm new scala, , i'm working through scala impatient cay horstmann. going until got comprehension, , came against cryptic passage (section 2.6, advanced loops , comprehensions): [start quote] the generated collection compatible first generator. for (c <- "hello"; <- 0 1) yield (c + i).tochar // yields "hieflmlmop" (i <- 0 1; c <- "hello") yield (c + i).tochar // yields vector('h', 'e', 'l', 'l', 'o', 'i', 'f', 'm', 'm', 'p') [end quote] indeed, running in repl, see result of first code snippet has type string, , second code snippet has type scala.collection.immutable.indexedseq[char]. why types differ? think understand second line of code, don't understand why first line doesn't have type scala.collection.immutable.indexedseq[char]. magic happening string rather vector? author mean "compatible first generator"?

just tried write program simulates simple system online game. idea behind is, let program calculate efficient set of items possible stat efficiency set. clarify bit more: you've got 8 item slots , 74 different items, can't use item twice, , doesn't matter item in slot. i'am not yet trying calculate 1 set of stats, i'am stuck way earlier! so problem number of possibilities (74^8) before filtering , (74 choose 8) after filtering. program starts lagging when try head(permu' 2). since know haskell supposed work infinite lists, how work list of 899 trillion entries? know takes lot of capacity pc that's why here ask: how treat big list in haskell can work it? the function simplified looks this: quicksort :: (ord a) => [a] -> [a] quicksort [] = [] quicksort [a] = [a] quicksort (x:xs) = (quicksort [y | y <- xs, y <= x]) ++ [x] ++ (quicksort [z | z <- xs , z > x]) eliminatedouble [] = [] eliminatedouble (x:xs) = if x `elem` xs eliminate

i wondering if can tell me if problem worth consider or how can fix if needed. we have web service written in java built using spring boot , running on amazon aws. used our other products , services internally. though endpoint public, there authentication prevents public access. one of our api accepts json parameter post method. our qe pointed out our api not detect extraneous data following json data. example, assuming our api expects data like: { "name": "john doe", "email": "john.doe@example.com" } our api not complain if following data given: { "name": "john doe", "email": "john.doe@example.com" } hello, i’m ignored! our api ignores extraneous portion completely. use jackson deserialize json string. looked jackson , spring documentation not able find out how can detected. so, question is: security threat? if so, how can fixed? thanks, masa i digged jackson source c

the case: var s = '{"a": 2}'; var d = json.parse(s); // d = object {a: 2} it ok. the similar case not parse string, however. why? var s = "{'a': 2}"; var d= json.parse(s) // uncaught syntaxerror: unexpected token ' in json @ position 1 expected result - parsed object in first case. should have worked because ' , " interchangeable in javascript. according standard , need double quotes denotes string, key is.

the code below compiles correctly on clang 3.8.1-1 on archlinux. is clang bug? gcc issue correct warning/error on this. template <class t> struct bugreproducer{ using size_type = typename t::size_type; int bug1(size_type count); int bug2(size_type count) const; static int bug3(size_type count); }; template <class t> int bugreproducer<t>::bug1(size_type const count){ // bug. must not allowed count = 5; // return use result... return count; } template <class t> int bugreproducer<t>::bug2(size_type const count) const{ // same const method count = 5; return count; } template <class t> int bugreproducer<t>::bug3(size_type const count){ // same static method count = 5; return count; } struct dummyvector{ using size_type = int; }; int main(){ using bugrepr = bugreproducer<dummyvector>; bugrepr reproducer; auto = reproducer.bug1(1); auto b = repr

my jupyter/ipython notebook executes functions in external .py. i need set breakpoints within these functions, inspect variables, single step, etc. it isn't practical use combination of print statements , throwing exceptions early-exit cell. i need kind of workflow. is possible hook third-party editor/ide view .py , somehow connect python runtime jupyter/ipython using? so if set breakpoint in external .py using ide , execute cell in notebook encounters said breakpoint, can continue navigate manually within ide. edit: i've found https://pypi.python.org/pypi/ipdb https://www.quora.com/what-are-your-favorite-tricks-for-ipython-notebook edit https://www.youtube.com/watch?v=jb2hhoahvce <-- video getting close i'm after, can't quite see how put together. video demonstrates spyder ide ipython prompt... wonder if maybe can run notebook through prompt , debug it. edit: looks though pycharm i'm after: https://www.jetbrains.com/help/pycharm/2016.1/tut

i want create uitableview cell , multiline input field (textview). height of textview or cell should increase automatically user enter text. hi there: has been bugging me day i've put think has cracked it. i'm assuming know how put basic tableview together. you need add uitextview each row, and, crucially, make tableviewcontroller delegate each uitextview. alongside array of string values each of rows, need have array of heights (cgfloats) each row. crucial aspect assign each textview numerical tag equal indexpath.row cell allows keep track of textview dealing with. start out array of identical values, idea update array needed when text gets big existing frame, demonstrate below. i implemented following 2 delegate functions bespoke function update layout required: func updatelayout(fortextview: uitextview) -> void { guard fortextview.tag < self.data.count else { return } // make sure we're not going try , access value not exist self.data[fo
