we using finagle stack , taught of adding zipkin tracing our micro-services. i able see our tracing happening parent finishes before child. i have opened issue here: https://github.com/openzipkin/docker-zipkin/issues/100 any appreciated. i recording wrong annotation i.e client instead of server. just simple change did trick. trace.traceservice("function1","test") sample working zipkin example: https://gist.github.com/akhilj876/3e38757c28d43924f296dd2d147c0bd9#file-zipkintracing_example-l34

given polygon s , point p lies outside s, imagine ant can follow straight line towards or away p. for shapes (fig. 1), there choice of p such ant can move unobstructed in @ least 1 of 2 possibilities: towards (t) p, or away (a) it. condition corresponds ray cast p intersecting perimeter of s 0 or 2 times. however, same shape (fig. 2) there may points lead blocked (b) regions, ant bump polygon whichever direction tries move in. yet other shapes (fig. 3) there may no choice of p leads no blocked regions. having blocked regions corresponds rays cast p intersect perimeter of s more 2 times. is there algorithm determines whether p exists satisfies condition given polygon s? if such points exist, can determine region contains them? find concave corners of polygon obstacle. each corner, extend 2 edges infinitely. sector between these 2 rays, , (as nico schertler pointed out) point-reflected region of sector, define point must obstacle not hide corner form point's rays

i kind of confused , know (not ambiguous or opinionated) roles of these programming languages when creating ionic mobile application 1: ionic 2: angularjs 3: c# 4: asp.net mvc how role contribute on creating ionic application. if have built app else did use , why? ionic framework hybrid mobile development, framework7 , has nothing back-end , server languages c# or architectural pattern mvc framework.ionic build on html5, css , javascript , angularjs, of them used design , front end purposes. but u can use c# , mvc backend, example can create webapi communicate front end.

i have mean stack project scaffolded using basic npm command. @ moment, bootstrap included using cdn: link(rel='stylesheet', href='https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css') my question how can add bootstrap using npm project works same cdn inclusion. in particular, when run npm install bootstrap a boostrap directory created within node_modules. however, if try include bootstrap.css directory, breaks glyphicon fonts. advise on how it? p.s. pose same question regarding angularjs itself. you can use browser package manager i.e bower bower offers generic, unopinionated solution problem of front-end package management, while exposing package dependency model via api can consumed more opinionated build stack. there no system wide dependencies, no dependencies shared between different apps, , dependency tree flat. if want more knowledge better , reliable read link also. why not npm the main difference between npm ,

lets have simple python code this: num1 = input() num2 = input() res = sum(num1,num2) as per requirements, should able convert above code(that got input user) in such way, should able supply inputs predefined file. how ? , once add code, above works. if add input below "num3=input()", should raise error eoferror: eof when reading line. how raise error ? num1 = input() num2 = input() num3 = input() res = sum(num1,num2) please let me know questions. well far know there's no way tell pythons input function read stdin. without rewriting code use file objects, redirect file stdin. send eof @ end of file , raise error you're expecting. for example run: python script.py < file.in or if have shebang on first line of file , you've made executable: ./script.py < file.in this assuming you're running linux based or posix shell.
